PERSONALIZED TREATMENT OF CANCER: THE CONTRIBUTION OF GENOMICS

Thanks to technical advances, it is now possible to study the entire genome of a tumor to select the most appropriate treatment in the management of the patient.

The research contributes to the development of a growing number of antitumor drugs particularly promising targeted therapies. These treatments are highly effective in their specificity of action: they act, in effect, on cells that have precise molecular characteristics associated with their malignant nature. Therefore, these new drugs are only effective in patients whose tumor carries specific abnormalities. Their administration thus requires genetic characterization of tumor cells to destroy.

A strategy to obtain maximum information on tumors is genomic sequencing. This strategy is to decipher the entire genetic makeup of tumor cells in order to catalog all the flaws that entail. By comparing the resulting catalog to the arsenal of available targeted therapies, doctors can more easily choose the most appropriate treatment in the management of patients.
Personalized Cancer Treatment

This approach has remained utopian sequence an entire genome was indeed a work far too long and as well costly for it to be done in order to choose an anti-tumor therapy. However, today the situation is different: an American team has indeed demonstrated that it is possible to analyze the genetic makeup of a tumor in three to four weeks, for approximately $ 3,809. This period is consistent with the initiation of treatment, and the cost is not significantly higher than other methods currently used to characterize tumors.

It remains a problem to solve: in their pilot study of four patients, U.S. researchers have identified genetic defects that can be targeted by drugs currently being evaluated. However, patients have benefited from these treatments: testing clinics being focused on the use of these drugs in cancers other than those they developed.

Thus, the use of sequencing to facilitate personalized treatment can be considered without a change in the implementation of clinical trials to evaluate the effectiveness of new targeted therapies.

Stomach Cancer Causes

Stomach Cancer Causes

Even though the precise cause of Crohn's disease is tranquil unidentified, an arrangement of ecological factors and genetic predisposition seem to be the cause of disease. Genetic risk factors have been fully elucidated, making it the first Crohn's disease, genetic diseases, complex, whose origin was understood. The relative risk of contracting disease, which is a mutation of one gene, the risks are in fact very low (about 1:200). Generally speaking, the genetic data suggest that the immune system in patients with congenital disorder Crohn's disease and the direct evaluation of the patient's immune function confirms this. This disease is seen as innate immunity, is "Chronic inflammation caused by adaptive immunity trying to compensate for decreased function of the innate immune system.

Genetics

Some studies indicate that Crohn's disease may have a genetic cause. People who have a brother or sister withthe disease, has thirty times more possible to develop than the wide-ranging population.

Mutations inthe CARD 15 gene (as well recognized as NOD2 gene) are associated with Crohn's disease. In previous studies had only two genes were associated with Crohn's disease, but scientists believe that genes play a role in more than thirty in the disease, either directly or indirectly through intermediary variables as the cause. Abnormalities of the XBP1 gene have only just been found that the causal factors of inflammatory bowel disease.

Environmental factors


Because of its prevalence in highly industrialized areas of the world, it is believed that the diet may be one of the causes of disease. Positive correlation between the incidence of disease and amplified ingestion of milk protein, animal protein and a higher proportion of omega6 polyunsaturated fatty acids and omega3. It was rather found a negative correlation of this disease in an increase in consumption of vegetable protein and no correlation with fish protein. The smoke turned out to be an important factor in increasing the risk of recurrence is active. The introduction of hormonal contraception in the United States in 1960 is associated with a dramatic increase in the incidence of Crohn's disease. Although a causal relationship has not been demonstrated in the fact that he still regards these drugs affect the digestive system in a similar way as with smoking. Numerous scientific studies have postulated a "isotretinoin as a possible cause of Crohn's disease in some individuals.

The immune system


Abnormalities in the immune system have often been considered because of Crohn's disease. Many believe that disease is an autoimmune disease caused by an abnormal response to cytokines lymphocytes. The gene, which more recent studies of closely related ATG16L1 with Crohn's disease, which may cause "autophagy and can hinder the body's ability to attack invasive bacteria.

Unlike prevalent suggests that Crohn's disease is a disorder of autoimmune T cells, some studies suggest that results from a deterioration of the innate immune system. Immunodeficiency virus, which has been shown that it is (at least partially) to reduce the secretion of cytokines by macrophages, is believed to be due to an inflammatory reaction, especially in the large intestine where the bacteria is very high.

GI symptoms
Endoscopy image of colon showing serpiginous ulcer, easily seen in Crohn's disease. Many people with Crohn's disease symptoms years before the diagnosis. Usually the onset is between 15 and 30 years, but can occur at any age. Due to the nature of "irregular" gastrointestinal disease and depth of tissue involvement can be the initial symptoms are more unstable than typical ulcerative colitis. People with Crohn's disease flare of chronic recurrent symptoms and blame the remission period.

Abdominal pain can be the first symptom of Crohn's disease. A "often accompanied by diarrhea, especially in those who underwent surgery. Diarrhea may be more or less bloody. The nature of the diarrhea in Crohn's disease depends on the part of the small intestine and colon involved. Ileiti usually leads to large volumes of watery stool. Colitis can result in less stool volume, but with a higher frequency. Fecal consistency may range from solid to weak. In severe cases, an individual more than 20 days and bowel discharge need to wake up at night to defecate. Blood in stool is less frequent in Crohn's disease compared with ulcerative colitis, but may be discovered in connection with Crohn's colitis. Intestinal draining blood are usually transient and may be bright red or dark. In severe colitis, Crohn's disease, it may be heavy bleeding. Bloating and swelling can be added to intestinal problems.
colon issues symptoms

Symptoms caused by stenosis are also common intestinal Crohn's disease. Abdominal pain is often acute in areas that narrowing of the intestine. In the context of severe stenosis, vomiting and nausea may indicate the beginning of small bowel obstruction. Although the correlation is higher in relation to ulcerative colitis, Crohn's disease may also be associated with primary sclerosing cholangitis, a type of inflammation of the bile ducts.

Problems in the perianal area may be important in Crohn's disease. Itching or pain around the "anus may indicate inflammation, fistulization or abscess around. Perianal skin tags are common. Faecal incontinence may accompany diseases of perianal Crohn's disease. At the opposite end of the digestive tract may be affected by non-healing wounds mouth (aphthous ulcers). Rarely the esophagus and stomach may be involved in disease. If disabled, can cause symptoms such as difficulty in swallowing (dysphagia), upper abdominal pain and vomiting.

Systemic symptoms

Crohn's disease, as well as many other chronic inflammatory diseases, can cause a number of systemic symptoms. In children, growth failure is common. Many of them are diagnosed with the disease due to their inability to maintain proper growth. Up to 30% of children with this disease with growth retardation. Fever may be present, even more to 38.5 ˚ C is rare, if there are no complications such as abscess. Elderly, Crohn's disease manifest as weight loss is usually related to decreased food intake, because patients with symptoms of intestinal Crohn's disease often feel better when not eating. People with this disease in a large part of the small intestine may also have malabsorption of carbohydrates or fats, which can further exacerbate weight loss.

Nutritional deficiency due to reduced intake of anorexia and self-imposed determines steatorrhea, megaloblastic or microcytic anemia, hypoprotidemia, edema, bone demineralization, dehydration and hypokalemia.

Chrons Disease Extraintestinal

In addition to systemic and gastrointestinal involvement of Crohn's disease can also affect many other organs. Inflammation of the eye, known as uveitis, can cause severe pain, especially when the eye is exposed to light (photophobia). Inflammation may also involve the white of the eye (sclera), a condition called episcleritis. Both episcleritis uveitis, which can lead to blindness if left untreated.

Crohn's disease is associated with the type of rheumatologic disease known as seronegative spondyloarthropathy. It is characterized by inflammation of one or more joints (arthritis) or muscle insertions (enthesitis). Arthritis can affect larger joints such as knees or shoulders, or may include only the small joints of hands and feet. Arthritis can also involve the spine, leading to ankylosing spondylitis if the entire structure is, or simply sacroiliitis if only the lower spine is involved. Symptoms of arthritis include pain, warmth, swelling, stiffness and loss of joint mobility or function.

Crohn's disease may also affect the skin, blood and endocrine system. Type of skin exposure, "erythema nodosum, shown as red nodules which usually appear on the shins. Erythema nodosum is due to inflammation of the subcutaneous base, and is characterized by septal panniculitis. Another skin lesion, pyoderma gangrenosum, is typically characterized by painful ulcerating node. Crohn's disease also increases the risk of blood clots, swelling and pain in the legs, and can be a symptom of deep vein thrombosis, while difficulty breathing may be due to pulmonary embolism. "Hemolytic anemia is an autoimmune disease in which the immune system attacks the red blood cells, which is common Crohn's disease and can cause fatigue, pallor, and other symptoms common in "anemia. Clubs, deformities at the ends of the fingers may be due to illness. Finally, Crohn's disease causes of osteoporosis and bone loss. People with osteoporosis are at increased risk of bone fractures .

Crohn's disease can cause complications, neurological (as reported in 15% of patients). The most common are seizures, stroke, myopathy, peripheral neuropathy, headache and depression.

Influence of disease may also suffer from granulomatous cheilitis and other forms of orofacial granulomatosis.

Chrons Disease Complication

Crohn's disease can lead to several complications in the intestines, including obstruction, development of fistulae and abscesses. Generally the block valve, or adhesions which narrow the lumen, blocking the passage of intestinal contents. Fistulae may develop between two loops bowel, between bowel and bladder, between the intestine and vagina, and between the intestine and skin. Abscesses may occur in the abdomen or in the perianal area.

Crohn's disease also increases the risk of cancer in the area of ​​inflammation. For example, people with Crohn's disease involving the small bowel are at increased risk of colon cancer. Likewise, people with Crohn's colitis have a relative risk of 5.6 for developing colon cancer. Screening for colorectal cancer with colonoscopy is designed for those with Crohn's colitis for at least eight years.

Individuals with Crohn's disease are at risk of malnutrition for many reasons, including reduced food intake and absorption. The risk increases after small bowel resection. These individuals may require oral supplements to increase their calorie intake, or in severe cases, parenteral nutrition, total (TPN). Most people with moderate to severe Crohn's disease turn to for help dietitian in nutrition.

Crohn's disease can be problematic during pregnancy and some medications can cause side effects on the fetus or mother. Consultation with the obstetrician and gastroenterologist about Crohn's disease and all medicines, it can be assumed, it may take preventive measures. In some cases, during pregnancy may lead to remission of the disease. Some drugs can affect sperm count, or information, may adversely affect fertility in men.

Other complications of the disease may be "infected Iris and" anorexia.

Crohn s Disease Cancer

Crohn's disease or Crohn's disease or IBD (inflammatory bowel disease) or also known as regional enteritis, is a disease chronic inflammatory bowel that can affect any part of the gastrointestinal tract , from mouth to  anus , causing a wide range of symptoms. It mainly causes abdominal pain , diarrhea (which may also be bloody if the inflammation is important), vomiting or weight loss , but it can moreover cause complication external the gastrointestinal tract just like skin rashes , rheumatoid arthritis , eye inflammation, fatigue and poor concentration.

Crohn's disease is believed to be an autoimmune disease where the immune system attacks the gastrointestinal tract causing inflammation, but is classified as a type of inflammatory bowel disease. There is evidence of a susceptibility gene for the disease and this leads us to consider individuals with sick brothers among individuals at high risk. Males and females are equally affected. Cigarette smokers have two times more likely to develop Crohn's disease than non-smokers. Crohn's disease affects between 400,000 and 600,000 people in North America. The prevalence estimated for Northern Europe ranges from 27 to 48 per 100,000 inhabitants. Crohn's disease tends to at hand at the outset in the teens and twenties, with another peak incidence between fifty and seventy years, even though the disease can come about at in the least age.
crohn s disease and cancer

There is no cure pharmaceutical or surgical known for Crohn's disease. The treatment options are limited to symptom control, maintenance of remission and relapse prevention.

The disease is named subsequent to American gastroenterologist BurrillBernard Crohn , which, in 1932 , along with 2 colleagues, described a sequence of patients with inflammation of ileus terminal, the area most affected by the disease. For this reason, the disease has also been called regional ileitis or regional enteritis.

How to Overcome Obesity and Cancer


In 2001, experts concluded that colon cancer, breast (postmenopausal), endometrium, kidney, and esophagus, associated with obesity. Obesity and low physical activity causes approximately 25 to 30% of major cancers such as colon cancer, breast (postmenopausal), endometrium, kidney and esophagus cancer.

Research conducted in the United States in patients over 16 years and non-Smokers, clearly shows that bboth men and women are more obese at baseline (with the examination-IMT), have a higher risk of suffering from cancer. In this study, an increased risk of cancers such as kidney and uterine cancer in women and liver cancer in men is surprising. Results from another study claimed that obesity is the cause of the 2nd cancer after smoking in the United States.

In the world, the increasing incidence of obesity and smoking is reduced, so that it is estimated that obesity 1 next decade will be the first risk factor for cancer in the United States. The results of this study were presented by the American Institute for Cancer Research and the World Cancer Research Fund International, with the theme: Food, Nutrition, Physical Activity, and the Prevention of Cancer: A Global Perspective. Now the estimated two thirds of the population in America is overweight.

Worldwide, the incidence of cancer is increasing faster than population growth. Although it has been known that obesity increases the incidence of cancer, but the quantity and cancer risks where the risk is increased still need further evaluation. The American Institute for Cancer Research and the World Cancer Research Fund International has gathered its members to evaluate the risk of cancer.

The data discussed is the data from 7000 study have been published. This all relates to food that you input into your stomach. daripda that naturopathy and natural organic food is believed to overcome them, because it heals the body from foods rather than drugs! visit info here
