Stomach cancer - dangerous malignant disease with localization in the gastric mucosa. It takes 2-3 third place on the prevalence of cancer among others. Most gastric cancer is usually found only malignant tumors of the lungs and chest.
The factors that trigger cancer of the stomach, are quite diverse. Here and in the wrong diet, and alcohol abuse, and smoking and infectious factor and a combined negative impact of the environment.
The symptoms of stomach cancer are diagnosed most often in people over the age of 50 years. For the diagnosis of the first signs of stomach cancer are very important annual preventive screening examinations. Only early detection of the symptoms of stomach cancer and early treatment gives the most optimistic forecast of stomach cancer, until the complete healing.
The symptoms of stomach cancer
In the early stages of stomach cancer the disease does not manifest itself, so its detection is possible only during a routine baseline medical examination. As a rule, the office of the gastroenterologist had patients come with complaints about certain health and clear symptoms of stomach cancer or other diseases of the digestive tract.
The first signs of stomach cancer, and expressed little haphazard. The patient often takes them for worsening of other chronic diseases, or seasonal malaise. In the worst case, at the first sign of stomach cancer - discomfort or pain, "the stomach" - the patient for a few more months to self-medicate with folk remedies. Although this time it is crucial to achieve the best results in the treatment of gastric cancer.
With the growth of the tumor to other signs of stomach cancer added aching pain on an empty stomach. Various drugs to reduce the acidity helps for a short time to facilitate the patient's condition, so the first signs of gastric cancer patients are often mistaken for gastritis or peptic ulcer disease beginning.
Common symptoms of stomach cancer are also reduced appetite and weight loss. Patients may be selective in the food disgusted to certain foods, such as meat or milk. At a late stage stomach cancer disease can manifest vomiting dark color and loose stools dark color. The symptoms of stomach cancer indicate internal bleeding, so the patient needs immediate hospitalization.
When the tumor in the upper part of the body a sign of gastric cancer is difficulty swallowing. When the total defeat of the stomach tumor and metastasis of the stomach wall are maloelastichnymi, and the patient quickly becomes saturated and feels a constant heaviness in the abdomen. The signs of stomach cancer at this stage of the disease also include exhaustion, vomiting and cause systemic obstruction of the stomach, yellowing of the skin, increasing the abdomen (ascites) and seal lymph nodes.
In the classification of gastric cancer using multiple attributes: the cellular structure of the tumor, the type of its growth, shape, size and prevalence of metastases in the human body. Accurate staging of gastric cancer allows you to assign adequate treatment of the disease and as objectively as possible to make a prediction.
Diagnosis zero stage stomach cancer rarely set. When a malignant tumor has its minimum size and is located in the surface layers of the gastric mucosa. 1-4 stage of gastric cancer are characterized by a deep tumor invasion into the wall of the body and the spread of metastasis to nearby lymph nodes and distant organs and. The best prognosis of gastric cancer with persistent treatment in 90% of cases in the first stage of gastric cancer.
Probability of complete cure or remission of the disease depends not only on the stage of gastric cancer, but also on its shape. Considered the most aggressive form of undifferentiated tumors. They are characterized by a high growth rate, rapid metastasis and consequently the worst prognosis. High-grade tumors distinguishes slow growth and low expression of metastasis.
Diagnosis of gastric cancer
The early diagnosis of gastric cancer blood test is applied to specific tumor markers CA 19-19, and CA 72-4. A precancerous condition of the patient with early symptoms of stomach cancer can also be detected during endoscopy with marker dyes.
In the later stages of stomach cancer are additionally used biopsy with further study to pick up the material, X-ray, computed tomography, magnetic resonance imaging, as well as laparoscopic diagnosis.
Treatment for stomach cancer
Treatment of gastric cancer based on three main methods: surgery, chemotherapy and radiation. The radicality of an operation depends on the stage of gastric cancer. Surgical treatment of gastric cancer is not carried out only in the presence of inoperable tumors and multiple complications due to extensive metastasis. In this case, the patient is assigned to preoperative, so-called non-adjuvanted chemotherapy. After reaching the size of the tumor resectable patients are referred for surgical treatment of gastric cancer.
When surgical treatment of gastric cancer are different types of resections: subtotal proximal or digistalnaya removing ¾ part of the stomach with fatty tissue and lymph nodes, or gastrectomy with complete removal of the stomach and adjacent areas of the intestine and esophagus. Palliative treatment for inoperable stomach cancer tumors is designed to temporarily improve the condition of the patient and eliminate obstruction of the digestive tract.
Treatment of gastric cancer in the postoperative phase complements Chemotherapy. For the prevention of recurrence of the disease, it applies even if the tumor mass was removed completely. If extensive metastasis of gastric cancer and lymph node chemotherapy significantly reduces the rate of disease progression, destroying most of the cells of tumor tissue.
Beam radiation in the treatment of gastric cancer is rarely used due to the low efficiency of the method in this type of tumor and a large number of complications.
