Lung cancer results from abnormal growth of cells in the lining of the lungs, leading to the growth of a malignant tumour.

There are two different types of lung cancer – small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) – which differ in terms of how they grow and spread to other parts of the body and how they’re treated.

 

Causes:

The development of lung cancer is strongly associated with cigarette smoking – approximately 90% of lung cancers are attributable to tobacco use. Pipe and cigar smoking can also cause lung cancer, but the risk is not as high as with cigarette smoking. Tobacco smoke contains more than 4,000 chemical compounds, many of which are cancer-causing (carcinogens).

Passive smoking, i.e. the inhalation of tobacco smoke by non-smokers who live or work with smokers, is also an established risk factor for the development of lung cancer.

Although the majority of lung cancers are linked to tobacco smoking, not all smokers go on to develop lung cancer suggesting that genetic susceptibility (i.e. family history) may play a role in the development of lung cancer.

Other causes of lung cancer include air pollution (from vehicles, industry, and power generation) and inhalation of asbestos fibres (usually in the workplace).

Signs, symptoms, and diagnosis :

Symptoms of lung cancer are varied and warning signs are not always obvious. Up to 25% of people who get lung cancer display no symptoms. In people who do display symptoms, they include the following:

• Persistent cough and hoarseness
• Shortness of breath, wheezing, and chest pain
• Blood-streaked sputum
• Chest pain
• Frequent episodes of bronchitis or pneumonia
• Weight loss, weakness, and fatigue.

A wide range of diagnostic tests and procedures are used to diagnose lung cancer, including taking a patient history, physical examination, blood tests, chest x-rays, computerized tomography (CT) and positron emission tomography (PET) scans, bone scans, bronchoscopy, cytological studies of sputum, bronchial washings, and fine needle biopsy. Many of these procedures are also used to determine the stage of the cancer.

Staging of lung cancer:

The stage of a lung cancer refers to the extent to which the cancer has spread to other parts of the body. Staging helps to determine how the cancer should be treated. Lung cancer can spread to any organ in the body but the liver, brain, and bones are the most common sites. The two types of lung cancer are staged differently. A simplified overview of staging is as follows:

NSCLC
Stage I: cancer that is confined to the lung
Stage II: cancer that is confined to the chest
Stage III: cancer that is confined to the chest but with larger and more aggressive tumours than at stage II
Stage VI: cancer that has spread to other parts of the body.

SCLC
Limited-stage: cancer confined to the area of the chest
Extensive-stage: cancer that has spread to other parts of the body.

Treatment :

Treatment for cancer involves a combination of surgery to remove cancer cells, and chemotherapy and radiation therapy to kill cancer cells. Lung cancer is incurable unless complete surgical removal of the tumour cells can be achieved.

Surgery is the most effective treatment for lung cancer but only about 20% of lung cancers are suitable for surgery i.e. Stage I and II NSCLC and cancer that has not spread beyond the lung.

Radiation therapy may be used for both NSCLC and SCLC and is a good option for people are not suitable for surgery or who refuse surgery.

Chemotherapy is used for both NSCLC and SCLC. Chemotherapy drugs may be given alone or in combination with surgery or radiation therapy. Chemotherapy is the treatment of first choice for SCLC since it has usually spread extensively in the body by the time it has been diagnosed.

Also used in the treatment of lung cancer are targeted therapies. These are drugs (gefitinib and erlotinib) or antibodies (cetuximab, bevacizumab) that block the growth and spread of cancer by interfering with specific molecules involved in tumour growth and progression. They are used in some patients with NSCLC that does not respond to standard chemotherapy.

Prevention :

The most effective measure that can be taken to prevent the development of lung cancer is to stop smoking. Reducing exposure to passive smoking is also an effective method of prevention.

Adenocarcinoma

Adenocarcinoma is a type of cancer that forms in mucus-secreting glands throughout the body. It can occur in many different places in the body, and is most prevalent in the following cancer types:

• Lung cancer: Non-small cell lung cancer accounts for 80 percent of lung cancers, and adenocarcinoma is the most common type.
• Prostate cancer: Cancer that forms in the prostate gland is typically an adenocarcinoma, which makes up 99 percent of all prostate cancers.
• Pancreatic cancer: Exocrine pancreatic cancer tumors are called adenocarcinomas. They form in the pancreas ducts.
• Esophageal cancer: Cancer that forms in the glandular cells of the esophagus is known as adenocarcinoma. This is the most common type of esophageal cancer.
• Colorectal cancer: Cancer that develops in the intestinal gland cells that line the inside of the colon and/or rectum is an adenocarcinoma. It makes up 95 percent of colon and rectal cancers.

Adenocarcinoma can also develop elsewhere in the body.

Diagnosing adenocarcinoma

Diagnostic tests vary according to where the cancer is located. When diagnosing adenocarcinoma, the following tests may be performed:

• Biopsy: The removal of a sample of abnormal tissue in the body. Once the tissue is removed, a pathologist can examine it under a microscope to determine whether cancer is present. If cancer is present, a biopsy can determine whether the cancer originated at the biopsied site or in another part of the body.
• Computerized tomography (CT) scan: An X-ray procedure that uses a computer to take detailed, three-dimensional pictures of abnormal tissue in the body. CT scans are also performed during treatment to check the effectiveness of current treatment.
• Magnetic resonance imaging (MRI): Uses radiofrequency waves to create detailed cross-sectional images of different parts of the body.

Adenocarcinoma treatment & therapy options

Treatment for adenocarcinoma varies depending on where it grows in the body, but may include:

• Surgery: Adenocarcinoma is often treated with surgical removal of cancerous glandular tissue, as well as some surrounding tissue. Minimally invasive surgical treatment methods can help to reduce healing time and minimize the risk of infection after surgery.
• Radiation therapy: This adenocarcinoma treatment option is typically used in combination with surgery and/or chemotherapy. Advanced radiation therapies make use of image guidance before and during treatment to target adenocarcinoma tumors, while sparing healthy tissues and surrounding organs.
• Chemotherapy: Chemotherapy treats adenocarcinoma with drugs that destroy cancer cells, either throughout the whole body, or in a specific area. In some cases, chemotherapy may be used in combination with other forms of adenocarcinoma treatment, such as radiation therapy or surgery.

The liver weighs about 3 pounds and is the largest solid organ in the body. It performs many important functions, such as:

Manufacturing blood proteins that aid in clotting, oxygen transport, and immune system function,
Storing excess nutrients and returning some of the nutrients to the bloodstream,
Manufacturing bile, a substance needed to help digest food,
Helping the body store sugar (glucose) in the form of glycogen,
Ridding the body of harmful substances in the bloodstream, including drugs and alcohol,
Breaking down saturated fat and producing cholesterol.
Cirrhosis is a slowly progressing disease in which healthy liver tissue is replaced with scar tissue, eventually, preventing the liver from functioning properly. The scar tissue blocks the flow of blood through the liver and slows the processing of nutrients, hormones, drugs, and naturally produced toxins. It also slows the production of proteins and other substances made by the liver.

According to the National Institutes of Health, cirrhosis is the 12th leading cause of death by disease.

What Causes Cirrhosis of the Liver?

Hepatitis C, fatty liver, and alcohol abuse are the most common causes of cirrhosis of the liver in the U.S., but anything that damages the liver can cause cirrhosis, including:

Fatty liver associated with obesity and diabetes
Chronic viral infections of the liver (hepatitis types B, C, and D; Hepatitis D is extremely rare)
Blockage of the bile duct, which carries bile formed in the liver to the intestines, where it helps in the digestion of fats; in babies, this can be caused by biliary atresia in which bile ducts are absent or damaged, causing bile to back up in the liver. In adults, bile ducts may become inflamed, blocked, or scarred, due to another liver disease called primary biliary cirrhosis.
Repeated bouts of heart failure with fluid backing up into the liver Certain inherited diseases such as:

Cystic fibrosis, Glycogen storage diseases, in which the body is unable to process glycogen, a form of sugar that is converted to glucose and serves as a source of energy for the body. Alpha 1 antitrypsin deficiency, an absence of a specific enzyme in the liver. Diseases caused by abnormal liver function, such as hemochromatosis, a condition in which excessive iron is absorbed and deposited into the liver and other organs, and Wilson’s disease, caused by the abnormal storage of copper in the liver. Although less likely, other causes of cirrhosis include reactions to prescription drugs, prolonged exposure to environmental toxins, or parasitic infections.

Do People Who Drink A Lot of Alcohol Always Get Cirrhosis of the Liver?

Most people who drink large amounts of alcohol harm their livers in some way, but not all of these people get cirrhosis of the liver. Women who are heavy drinkers are at higher risk than men. People who have hepatitis B or hepatitis C are more likely to suffer liver damage from alcohol.

What Are the Symptoms of Cirrhosis of the Liver?
The symptoms of cirrhosis of the liver vary with the stage of the illness. In the beginning stages, there may not be any symptoms. As the disease worsens, symptoms may include:

1.Loss of appetite
2.Lack of energy (fatigue), which may be debilitating
3.Weight loss or sudden weight gain
4. Bruises
5. Yellowing of skin or the whites of eyes (jaundice)
6. Itchy skin
7. Fluid retention (edema) and swelling in the ankles, legs, and abdomen (often an early sign)
8. A brownish or orange tint to the urine
9. Light colored stools
10.Confusion, disorientation, personality changes
11. Blood in the stool
12. Fever

How Is Cirrhosis of the Liver Diagnosed?
Cirrhosis of the liver is diagnosed through several methods:

Physical exam. During a physical exam, your doctor can observe changes in how your liver feels or how large it is (a cirrhotic liver is bumpy and irregular instead of smooth).
Blood tests. If your doctor suspects cirrhosis, you will be given blood tests to find out if liver disease is present.
Other tests. In some cases, other tests that take pictures of the liver are performed, such as a computerized tomography (CT scan), ultrasound, or another specialized procedure called a radioisotope liver/spleen scan.
Biopsy. Your doctor may decide to confirm the diagnosis by taking a sample of tissue (biopsy) from the liver.
Surgery. In some cases, cirrhosis is diagnosed during surgery when the doctor is able to see the entire liver. The liver also can be inspected through a laparoscope, a viewing device that is inserted through a tiny incision in the abdomen.

What Complications Are Caused by Cirrhosis of the Liver?

Complications associated with cirrhosis of the liver include:

Variceal bleeding. Variceal bleeding is caused by portal hypertension, which is an increase in the pressure within the portal vein (the large vessel that carries blood from the digestive organs to the liver). This increase in pressure is caused by a blockage of blood flow through the liver as a result of cirrhosis. Increased pressure in the portal vein causes other veins in the body to enlarge (varices), such as those in the esophagus and stomach, to bypass the blockage. These varices become fragile and can bleed easily, causing severe hemorrhaging and fluid in the abdomen.
Confused thinking and other mental changes (hepatic encephalopathy). Hepatic encephalopathy most often occurs when cirrhosis has been present for a long time. Toxins produced in our intestines are normally detoxified by the liver, but once cirrhosis occurs, the liver cannot detoxify as well. Toxins get into the bloodstream and can cause confusion, changes in behavior, and even coma.

Other serious complications of cirrhosis of the liver include:

1. Kidney failure
2. Reduced oxygen in the blood
3. Diabetes
4. Changes in blood counts
5. Increased risk of infections
6. Excessive bleeding and bruising
7. Breast enlargement in men
8. Premature menopause
9. Loss of muscle mass
Most of these complications can initially be treated with medicines or dietary changes. Once treatment for these complications becomes ineffective, a liver transplant is considered. Almost all of the complications can be cured by liver transplantation; however, in many circumstances, careful management can reduce the harmful effects of cirrhosis and delay or even prevent the need for a liver transplant.

What Is the Treatment for Cirrhosis of the Liver?
Although there is no cure for cirrhosis of the liver, there are treatments available that can stop or delay its progress, minimize the damage to liver cells, and reduce complications.

The treatment used depends on the cause of cirrhosis of the liver.

For cirrhosis caused by alcohol abuse, the person must stop drinking alcohol to halt the progression of cirrhosis.
If a person has hepatitis, the doctor may prescribe steroids or antiviral drugs to reduce liver cell injury.
For people with cirrhosis caused by autoimmune diseases, Wilson’s disease, or hemochromatosis, the treatment varies. Medications may be given to control the symptoms of cirrhosis. Edema (fluid retention) and ascites (fluid in the abdomen) are treated, in part, by reducing salt in the diet. Drugs called diuretics are used to remove excess fluid and to prevent edema from recurring. Diet and drug therapies can help improve the altered mental function that cirrhosis can cause. Laxatives such as lactulose may be given to help absorb toxins and speed their removal from the intestines.

Liver transplantation may be needed for some people with severe cirrhosis.

How Can I Prevent Cirrhosis of the Liver?

There are several ways to reduce your risk of developing cirrhosis of the liver:

Don’t abuse alcohol. If you do drink alcohol, limit how much you drink and how often. Remember, it’s not only the heavy drinker who gets cirrhosis. If you drink more than 2 drinks a day, you are increasing your risk. A drink is a 5-oz glass of wine, a 12-oz can of beer, or a 1 1/2-oz portion of hard liquor.
Avoid high-risk sexual behavior such as unprotected sexual contact with multiple partners.
Be careful around synthetic chemicals, such as cleaning products and pesticides. If you come into contact with chemicals often, wear protective clothing and a facemask.
Get vaccinated against hepatitis B.
Eat a well-balanced, low-fat diet high in fruits and vegetables and take vitamins.
Maintain a healthy weight, because excess body fat can cause fatty liver, which may lead to liver disease.

Lumpectomy is a surgical procedure that involves removing a suspected malignant (cancerous) tumor, or lump, and a small portion of the surrounding tissue from a woman’s breast. This tissue is then tested to determine if it contains cancerous cells. A number of lymph nodes may also be removed to test them for cancerous cells (sentinel lymph node biopsy or axillary dissection). If cancerous cells are discovered in the tissue sample or nodes, additional surgery or treatment may be necessary. Women who undergo a lumpectomy normally receive radiation therapy (RT) for about six weeks following the procedure to kill any cancer cells that may have been missed with the removal of the tumor. Lumpectomy is also referred to as partial mastectomy, wedge resection, breast conserving therapy, wide excision biopsy, tylectomy, segmental excision, and quadrantectomy.

A few decades ago, the standard surgical procedure to treat breast cancer was radical mastectomy, which involves the complete removal of the breast, muscles from the chest wall and all the lymph nodes in the armpit. Lumpectomy replaced radical mastectomy as the preferred surgical treatment because lumpectomy is designed to leave the natural appearance and cosmetic quality of the breast mostly intact while removing the malignancy. In addition, studies have shown that lumpectomy with radiation treatment is as effective as mastectomy in treating breast cancer.

The size and location of the lump determine how much of the breast is removed during a lumpectomy. A quadrantectomy, for example, involves removing a quarter of the breast. Before surgery, a woman should discuss with her doctor how much of the breast will be involved so that she can know what to expect.

The size of the cancer in relation to the size of the breast is the main factor that a woman’s doctor considers to determine if a lumpectomy is an appropriate treatment. Additionally, some of the features of the cancer (if it is confined to one area of the breast and does not involve the skin or chest wall) help the doctor determine if lumpectomy is appropriate. Most women who are diagnosed with breast cancer, especially those who are diagnosed early, are considered good candidates for lumpectomy. However, under some circumstances, lumpectomy is not a recommended surgery for some women. These factors include the following:

• Multiple cancers in separate locations of the same breast: This means that the potentially malignant tissue cannot all be removed from a single location, meaning that the breast may become drastically disfigured as a result of lumpectomy.
• Prior lumpectomy with radiation: Women who have had a lumpectomy with radiation therapy to remove cancer cannot have more radiation; therefore, they usually need a mastectomy if they experience cancer again in the same breast.
• Extensive cancer: Since a lumpectomy removes a specific area with malignancy, this surgery option would be inappropriate if the cancer has spread to other locations.
• Problematic tumors: A tumor that is rapidly growing or has attached itself to a nearby structure, such as the chest wall or skin, may require surgery that is more extensive to remove the tumor.
• Pregnancy: Radiation therapy, which usually follows the lumpectomy, can damage the woman’s fetus.
• Large tumors: Lumpectomy to remove a tumor that is larger than 5cm in diameter may drastically disfigure the breast. However, in some cases, the size of the tumor may be able to be reduced with chemotherapy, or endocrine therapy, to a size that is more manageable with lumpectomy. Small breasts, especially those that contain large lumps, may also be drastically disfigured after lumpectomy.
• Preexisting conditions that make radiation treatment more risky than usual: Radiation treatment may scar or damage connective tissue in women with collagen vascular diseases, such as scleroderma or lupus erythematosus.
• Prior radiation to the chest area, for instance, to treat Hodgkin’s disease.

Some women may prefer the idea of a mastectomy to lumpectomy in order to feel more confident that they will not develop breast cancer again. Other women may not feel comfortable with radiation therapy or be able to commit to a series of radiation treatments, which may involve an unacceptable time commitment or extensive travel. In most situations, though, women can safely choose between lumpectomy and mastectomy.

 

Endoscopic Retrograde Cholangiopancreatography (ERCP):

ERCP enables the physician to diagnose problems in the gallbladder, bile ducts, and pancreas. The liver is a large organ that makes a liquid called bile that helps with digestion. The gallbladder is a small, pear-shaped organ that stores bile until it is needed for digestion. The bile ducts are tubes that carry bile from the liver to the gallbladder and small intestine. These ducts are called the biliary tree. The pancreas is a large gland that produces chemicals that help with digestion and also secretes hormones such as insulin.

Applications

ERCP is primarily used as a therapeutic procedure for treatment of diseases of

• Bile duct

  • extraction of bile duct stones by balloon/basket (balloon/basket extraction)
  • by crushing large bile stones and retrieving them (mechanical lithotripsy)
  • relieving jaundice due to bile duct narrowing by dilating passage with balloon (balloon dilation)
  • treatment of bile duct infection (cholangitis) by draining pus by cutting open bile duct opening (biliary sphincterotomy) and placing stents /catheter in bile duct for free drainage of bile into duodenum ( plastic stent/ENBD placement)
  • stopping leakage of bile in bile duct injuries as a result of trauma and surgery
  • metallic stent placement for relief of itcing and jaundice in bile duct, pancreatic, gallbladder cancers (metallic stent placement)

• Pancreas

  • relief of pain in chronic pancreatitis
  • by removal of pancreatic duct stones
  • dilating the narrowed pancreatic duct
  • placing of stents to facilitate drainage of infected fluid collection in pancreatitis (Pseudocyst drainage)

How is ERCP performed?

ERCP combines the use of X-rays and an endoscope, which is a long, flexible, lighted tube. Through the endoscope, the physician can see the inside of the stomach and duodenum, and inject dyes into the ducts in the biliary tree and pancreas so they can be seen on X-rays.

For the procedure, you will lie on your left side on an examining table in an X-ray room. You will be given medication to help numb the back of your throat and a sedative to help you relax during the examination. You will swallow the endoscope, and the physician will then guide the scope through your oesophagus, stomach, and duodenum until it reaches the spot where the ducts of the biliary tree and pancreas open into the duodenum. At this time, you will be turned to lie flat on your stomach, and the physician will pass a small plastic tube through the scope. Through the tube, the physician will inject a dye into the ducts to make them show up clearly on X-rays. X-rays are taken as soon as the dye is injected.

Radiation therapy uses high-energy radiation to kill cancer cells by damaging their DNA directly or create charged particles (free radicals) within the cells that can in turn damage the DNA. X-rays, gamma rays, and charged particles are types of radiation used for cancer treatment. The radiation used for cancer treatment may come from a machine outside the body (external radiotherapy), or it may come from radioactive material placed in the body near Tumour cells (brachytherapy) or injected into the bloodstream (I131 for thyroid cancers). A patient may receive radiation therapy before, during, or after surgery, depending on the type of cancer being treated. The type of radiation therapy may vary of the size of the Tumour, and location of the Tumour.

Intensity Modulated Radiotherapy uses hundreds of tiny radiation beam-shaping devices, called collimators, to deliver a single dose of radiation and modulating different doses to different areas of the Tumour. Intensity guided Radiotherapy using repeat imaging CT and PET scans to reduce dose to normal tissues and enhance dose to specific areas of Tumour. Stereotactic radiosurgery (SRS) can deliver one or more high doses of radiation to a small Tumour by using accurate image-guided Tumour targeting and patient positioning systems. Therefore, a high dose of radiation can be given without excess damage to normal tissue. Electron beams are also used to irradiate superficial tumors such as on skin while protons beams are shown to have fewer side effects than normal photons in treating deeper tissues. Hyperthermia has also been used in conjunction with radiation to improve the treatment outcomes in several cancers.

What is liver cancer ?
Liver cancer is the uncontrolled growth and spread of unhealthy cells in the liver. Cancer that starts in the liver is primary liver cancer. Cancer that spreads to the liver from another organ (such as bowel or breast) is known as secondary or metastatic liver cancer.

What is the difference between liver tumor and liver cancer ? 
Any mass or nodule in the liver is known as a liver tumor. Liver tumors can be non-cancerous (benign) or cancerous (malignant). The most common type of cancer that originates in the liver is hepatocellular carcinoma (HCC).

What are the causes of primary liver cancer ?
There is no one cause of primary liver cancer. Several factors increase a person’s likelihood of developing liver cancer. Some risk factors for liver cancer include:
Viral hepatitis – Hepatitis B virus (HBV) and Hepatitis C virus (HCV) infections are an important cause for the development of liver cancer. It is estimated that about 5-10 percent of people with HBV or HCV will develop liver cancer.

• Cirrhosis is a progressive disorder that leads to scarring of the liver. Cirrhosis is the end result of all forms of long standing liver damage. Cirrhosis is caused by Hepatitis B, Hepatitis C, alcohol abuse, fatty liver and certain genetic disorders.  5-10 percent of patients with cirrhosis will develop liver cancer.
• Toxins such as Arsenic – Drinking water (usually well water) contaminated with arsenic also increase risk for developing liver cancer. Obesity may increase the risk of liver cancer.
• Diabetes can increase the risk of liver cancer, especially in those who drink alcohol heavily or have chronic viral hepatitis B or C infection.

What are the symptoms of liver cancer ?
Liver cancer usually has no obvious symptoms, and people at risk should be followed regularly to detect cancer at an early stage. The following symptoms might be caused by liver cancer:
Unexplained weight loss
Anorexia (persistent lack of appetite)
Early satiety (feeling very full after a small meal)
Persistent abdominal pain
Increasing abdominal girth (swelling of the “stomach” area) with or without breathing difficulty
Sudden jaundice (yellowness of the skin and eyes)
Sudden deterioration in the overall condition of a patient with cirrhosis
Liver enlargement or a mass that can be felt in the area of the liver

What tests will I have to detect liver cancer ?
If liver cancer is suspected, the doctor will conduct a physical examination and order special tests. Further tests may include alpha-fetoprotein (AFP) blood test, ultrasound scan, computed tomography (CT), magnetic resonance imaging (MRI), angiography, laparoscopy and biopsy. It is important to detect liver cancers early because small cancers in a patient who has minimal symptoms can be treated effectively.

What is liver cancer screening ?
Liver cancer screening is the best way to detect liver cancer early in its course. It is performed to detect small cancers that do not produce any symptoms. Small cancers can be treated more effectively. Patients who have a liver disease that puts them at a high risk of developing liver cancer (such as hepatitis B, any form of cirrhosis) should undergo periodic screening tests. It usually involves a blood test to look for a cancer marker (alpha-feto-protein) and an ultrasound scan of the liver to look for actual cancer. You must understand that screening tests are not 100 percent accurate and your doctor may advise you additional tests if he suspects that you may have a liver cancer.

How is liver cancer treated ?
Liver cancer treatment depends on:
The liver’s condition
The size, location, and number of tumors
If the cancer has spread outside the liver
The person’s age and overall health

Different ways of treating liver cancer are:
Surgery: If the cancer has been found early and the rest of the liver is healthy, doctors may perform surgery to remove the tumor from the liver.
Cryosurgery: Cryosurgery uses a metal probe to freeze and destroy cancer cells.
Radiofrequency Ablation: Radio frequency ablation uses a special probe to destroy cancer cells with heat using special needle. The procedure is performed under ultrasound or laparoscopic guidance.
Chemotherapy or chemoembolization: Chemotherapy uses anti-cancer drugs to destroy cancer cells. In some cases, the chemotherapy can be directly injected into the liver tumor.
Radiation Therapy: Radiation therapy uses radiation (high-energy x-rays) to destroy cancer cells.
Oral chemotherapy drugs : Sorafenib is an oral medication for use in advanced cases of liver cancer.

Can a liver transplant be done for liver cancer ?
Surgery is the most effective therapy for most types of liver cancer, but doctors will usually combine different methods to treat the cancer most effectively. When surgery to remove the cancer itself cannot be performed, your doctor may suggest a liver transplantation in which the cancer along with the entire liver is replaced thus curing the patient.

Pancreatitis

Pancreatitis is serious disease in which there is a swelling in pancreas. The pancreas is a large gland behind the stomach and close to the duodenum. The function of pancreas is to secrete digestive enzymes into the small intestine through a tube called the pancreatic duct. These enzymes help digest fats, proteins, and carbohydrates in food. The pancreas also releases the hormones insulin and glucagon into the bloodstream. These hormones help the body use the glucose it takes from food for energy. Pancreatic disease occurs when the digestive enzymes are activated and begin attacking the pancreas. In very severe cases, pancreatitis can result in bleeding into the gland itself; serious tissue damage, infection and fluid collections may occur. Severe pancreatitis can result in damage to other very important organs such as the heart, lung and kidneys. In approximately 70% of the cases, pancreatitis occurs when person consumes excessive, alcohol for longer period of time. It may happen due to metabolic disorders. It’s rare that patients have chronic pancreatitis that tends to run in families (hereditary pancreatitis). Alcohol damages the pancreas but patient may not show symptoms for many years. It occurs suddenly and patient show severe pancreatitis symptoms, including severe pain and loss of pancreatic function, resulting in digestion and blood sugar abnormalities.
There are two types of pancreatitis. The first category is acute pancreatitis which occurs suddenly and may result in critical complications. According medical data, the majority of patients get well completely from this type of pancreatitis. Chronic pancreatitis is usually the result of longstanding harm to the pancreas from alcohol intake. In chronic pancreatitis, patient complains severe pain and there is loss of pancreatic function.

Causes:

Acute pancreatitis is more common in men than women. Chronic pancreatitis may be due to metabolic, hereditary, or simply the causes are unidentified. Pregnancy can also cause ancreatitis, but in some cases the development of pancreatitis is most likely just a reflection of the hyper triglyceridemia which often occurs in pregnant women. Pancreas divisum, a common congenital deformity of the pancreas may cause some cases of frequent pancreatitis. Gallstones in the gallbladder which is another organ in the abdomen may be a cause of pancreatitis because a gallstone can block the pancreatic duct, trapping digestive juices inside the pancreas. Pancreatitis due to gallstones occurs most often in women who are above 50 years. Other causes are usually due to medications and very rarely, infections, trauma or surgery of the abdomen. Types of trauma can cause acute pancreatitis in rare cases. Trauma can be postoperative trauma (due to surgery), hyperlipidemia (or excessive amounts of fat and fatty substances in the blood), hypercalcemia (or an abnormally large amount of calcium in the blood), Ductal obstruction, Infectious Agents. Other causes, including Tropical pancreatitis, hereditary pancreatitis, hyperparathyroidism, cystic Fibrosis, pancreas Divisum.

Symptoms:

Pancreatitis patient complains pain in the upper abdomen that may last for a few days. The pain may be severe and may become constant just in the abdomen or it may reach to the back and other areas. It may be sudden and severe or start as a mild pain that gets worse when food is eaten. Acute pancreatitis may be a symptom of gallstone disease. The relation between gallstones and acute pancreatitis is the anatomical union of the ducts that drain the gallbladder and pancreas, called the ampulla or major papilla of the duodenum. In mild cases, a person is having problem in eating for 3 or 4 days and he has to receive fluids and pain relievers through an intravenous line. The pain occurs more often and lasts longer. Patient loses weight as the time passes and show symptoms of diabetes, including increased thirst, appetite, urination, fatigue, and weight loss. General symptoms of chronic pancreatitis include Pain, malabsorption of food leading to weight loss or diarrhea, diabetes, nausea, vomiting, fever and increased heart rate.
Patients must seek medical advice when they have intense, persistent abdominal pain, consult doctor to determine whether it is a symptom of pancreatitis or some other medical condition is the cause. It’s important to diagnose pancreatitis early in order to avoid severe and permanent damage to pancreas.

Complications:

Numerous complications may develop in severe cases of acute pancreatitis. A damaged pancreas may become infected with bacteria that spread from the small intestine into the pancreas. Signs of infection include fever, an elevated white blood cell count and, in severe cases, organ failure. Pancreatic infections can be deadly without thorough treatment, including drainage or surgery to remove the infected tissue. Sometimes doctor perform multiple operations. Another complication is pseudocysts. These are collections of pancreatic fluid and sometimes tissue debris that form within pancreas or in an obstructed duct. If the cyst is small, no particular care may be needed, but large, infected or bleeding pseudocysts need instant treatment. Abscess is a collection of pus in or near pancreas that may develop after the inception of acute pancreatitis. Treatment involves drainage of the abscess by catheter or surgery. There may be respiratory failure. Chemical changes in patient’s body can affect his lung function, causing the level of oxygen in blood to fall to severely low levels. Shock usually occurs when blood pressure is very low so that patient’s organs can not carry out their normal functions. Severe shock can cause death within minutes if treatment is not given immediately. Chronic pancreatitis can lead to bleeding because constant inflammation and damage to the blood vessels surrounding the pancreas cause potentially fatal bleeding. Patient may be drug addict. It is due to medical treatments for severe pancreatic pain is not always effectual. Pancreatic cancer. Long-term inflammation of the pancreas increases your risk of pancreatic cancer, one of the most serious of all malignancies.

Diagnosis:

Physicians diagnose pancreatitis by checking the blood for levels of digestive enzymes such as amylase and lipase helps. If the level of these two enzymes is high in the blood then it is diagnosed as acute pancreatitis. As the patient recovers, the digestive enzyme levels will decrease to normal. Chronic pancreatitis generally is assumed when the patient has symptoms and risk factors such as heavy alcohol intake. Diagnosis can be complicated. Doctors use new techniques, including pancreatic function tests and x-ray imaging of the pancreas gland with a CT scan or retrograde pancreatography (ERCP) to diagnose it.

Treatment:

Treatment plan for acute pancreatitis is supportive management in the hospital. Generally, patients are given intravenous fluids and pain medication. Medical records, represent that approximately 20 percent of patients, the pancreatitis can be severe. The patient may need to be admitted in the intensive care unit because of damage that has occurred to other important organs such as the heart, lungs or kidneys. In some severe cases, surgery is done to remove permanently damaged parts of the gland. Chronic pancreatitis can be very difficult to treat. Medical doctors try to alleviate pain and improve nutritional and metabolic problems that result from pancreatic function loss. Patients are generally given pancreatic enzymes and insulin to supplement as it is not being secreted or released by the pancreas. In some instances, obstruction of the pancreatic duct would need a surgical drainage procedure.

Prevention:

It is a fact that pancreatitis occurs all of sudden and can not be prevented but patients can some precautions to reduce risk. They must not consume excessive alcohol. Smoking is also risk factor for this disease. Excessive fat intake must be avoided. Eating a high-fat diet can raise blood-fat levels and increase risk of gallstones which can lead to pancreatitis. A healthy diet comprises fresh fruits and vegetables, whole grains, and lean protein, and limits fats, especially saturated fats such as butter. Person must have to develop good habits and modify Lifestyle to avoid this disease. Chronic pancreatitis may have bad consequences such as pain and malabsorption of certain nutrients. It is better to avoid alcohol. Person must eat meals at short intervals. fat intake should be limited in diet. It will help reduce weight and oily stools that result from a lack of pancreatic enzymes. Diet should be rich in carbohydrates. Carbohydrates provide energy to help fight tiredness. Person must obtain most of daily calories from complex carbohydrates found in grains, vegetables and legumes. If he has diabetes, he must consult a dietitian. Dietician can make appropriate diet plan. It is always recommended to drink plenty of liquids.

Patients of pancreatitis may suffer from cause emotional stress. In order to deal with such problems, person must maintain normal daily activities as best he can. He must be in touch with friends and family and continue to do activities that he enjoys. It is to understand that physical health can impact directly on mental health. Denial, anger and frustration are common with chronic illnesses. In this crisis period, person must seek help of professionals such as therapists or behavioral psychologists. They can provide good advice to resolve emotional problems. They can also educate patient how to develop coping skills which include relaxation techniques that may help patient to live better life. If patient is suffering from a chronic illness, he is at greater risk of depression. At this time, it is better for patient to discuss with family, friends and doctor to come out with depression. These strategies will help to fight with disease and patient will relax.

 

 

Signs and symptoms of ovarian cancer:

Ovarian cancer may cause several signs and symptoms. Women are more likely to have symptoms if the disease has spread beyond the ovaries, but even early- stage ovarian cancer can cause them. The most common symptoms include:
a.Bloating
b.Pelvic or abdominal pain
c.Trouble eating or feeling full quickly
d.Urinary symptoms such as urgency (always feeling like you have to go) or frequency (having to go often)

These symptoms are also commonly caused by benign (non-cancerous) diseases and by cancers of other organs. When they are caused by ovarian cancer, they tend to be persistent and represent a change from normal− for example, they occur more often or are more severe. If a woman has these symptoms more than 12 times a month, she should see her doctor, preferably a gynecologist.

Others symptoms of ovarian cancer can include:

1. Fatigue
2. Upset stomach
3. Back pain
4. Pain during sex
5. Constipation
6. Menstrual changes
7. Abdominal swelling with weight loss.

However, these symptoms are more likely to be caused by other conditions, and most of them occur just about as often in women who don’t have ovarian cancer.

Treatments for Ovarian Cancer:

a. Surgery for ovarian cancer

Surgery is the main treatment for most ovarian cancers. How much surgery you have depends on how far your cancer has spread and on your general health. For women of childbearing age who have certain kinds of tumors and whose cancer is in the earliest stage, it may be possible to treat the disease without removing both ovaries and the uterus.

For epithelial ovarian cancer, surgery has 2 main goals:ovarian-cancer-staging and debulking (this is discussed in detail further on). It’s important that this surgery is done by someone who’s experienced in ovarian cancer surgery.

Experts recommend that patients see a gynecologic oncologist for surgery. Gynecologic oncologists are specialists who have training and experience in treating, staging, and debulking ovarian cancer. If your cancer isn’t properly staged and debulked, you may need to have more surgery later. It has been shown that gynecologic oncologists are more likely than general surgeons and gynecologists to stage and debulk ovarian cancer optimally (see below).

For other types of ovarian cancer (germ cell tumors and stromal tumors), the main goal of surgery is to remove the cancer.

Staging epithelial ovarian cancer

Surgery for ovarian cancer has 2 main goals. The first goal is to the cancer − to see how far the cancer has spread from the ovary. Usually this means removing the uterus (this operation is called a hysterectomy), along with both ovaries and fallopian tubes (this is called a bilateral salpingo-oophorectomy or BSO). In addition, the omentum is also removed (an omentectomy). The omentum is a layer of fatty tissue that covers the abdominal contents like an apron, and ovarian cancer sometimes spreads to this tissue. Some lymph nodes in the pelvis and abdomen are biopsied (taken out to see if the cancer has spread from the ovary).

If there is fluid in the pelvis or abdominal cavity, it will also be removed for analysis. The surgeon may “wash” the abdominal cavity with salt water (saline) and send that fluid for analysis. He or she may also remove tissue samples from different areas inside the abdomen and pelvis. All the tissue and fluid samples taken during the operation are sent to a lab to be examined for cancer cells. ovarian-cancer-staging is very important because ovarian cancers at different stages are treated differently. If the staging isn’t done correctly, the doctor may not be able to decide on the best treatment.

Debulking epithelial ovarian cancer

The other important goal of surgery is to remove as much of the tumor as possible − this is called debulking.Debulking is very important in any patient with ovarian cancer that has already spread widely throughout the abdomen at the time of surgery. The aim of debulking surgery is to leave behind no tumors larger than 1 cm. This is calledoptimally debulked. Patients whose tumors have been optimally debulked, have a better outlook than those left with larger tumors after surgery (called sub-optimally debulked).

Sometimes the surgeon will need to remove a piece of colon to debulk the cancer properly. In some cases, a piece of colon is removed and then the 2 ends that remain are sewn back together. In other cases, though, the ends can’t be sewn back together right away. Instead, the top end of the colon is attached to an opening (stoma) in the skin of the abdomen to allow body wastes to get out. This is known as a colostomy. Most often, this is only temporary, and the ends of the colon can be reattached later in another operation.

Debulking surgery might also mean removing a piece of the bladder. If this occurs, a catheter (to empty the bladder) will be placed during surgery. This will be left in place until the bladder recovers enough to be able to empty on its own. Then, the catheter can be removed.

Debulking may also require removing the spleen and/or the gallbladder, as well as part of the stomach, liver, and/or pancreas.

If both ovaries and/or the uterus are removed, you will not be able to become pregnant. It also means that you will go into menopause if you haven’t done so already. Most women will stay in the hospital for 3 to 7 days after the operation and can resume their usual activities within 4 to 6 weeks.

Surgery for ovarian germ cell tumors and ovarian stromal tumors

Most ovarian germ cell tumors are treated with a hysterectomy and bilateral salpingo-oophorectomy. If the cancer is in only one ovary and the patient still wants to be able to have children, only the ovary containing the cancer and the fallopian tube on the same side are removed (leaving behind the other ovary and fallopian tube and the uterus).

Ovarian stromal tumors are often confined to just one ovary, so surgery may just remove that ovary. If the cancer has spread, more tissue may need to be removed. This could mean a hysterectomy and bilateral salpingo-oophorectomy and even debulking surgery.

b. Chemotherapy for ovarian cancer

The General Medicine deals with the prevention, diagnosis and non-surgical treatment of various diseases. It serves as the first point of contact whenever a patient visits the hospital. A general physician conducts a physical examination of the patient and then recommends necessary tests and diagnostic procedures. The results of these tests, the general physical examination and symptoms are then correlated to arrive at a final diagnosis. Depending on the final diagnosis, the general physician gives the necessary treatment (usually medication) to the patient or refers to a specialty department for further treatment.

The department of general medicine provides treatment for the following:

1. All types of fevers
2. Infections affecting different organs of the body
3. All metabolic diseases and endocrine diseases such as diabetes, thyroid, cholesterol, obesity.
4. Blood pressure
5. Tummy aches, infections like vomiting, diarrhea and jaundice
6. Infectious diseases
7. Respiratory diseases like asthma, allergies, lung infection, cough, sinusitis, pneumonia & TB
8. Disease of the joints and limbs, backache
9. Problems like headache, muscular weakness, epilepsy.

There are many different factors that can affect the fertility of both women and men. Even if you are not currently trying for a baby you may be wondering, or have concerns about your fertility health. There are various screening tests that can be done to evaluate fertility for both women and men
