Stomach cancer is a malignant tumor that develops from the mucous membrane. Included in the list of the most common malignant neoplasms. In the TARRGET clinic, you can undergo diagnosis and treatment of stomach cancer using modern methods.
Stomach cancer types
In 90% of cases, adenocarcinoma is diagnosed, which develops from the glandular tissue lining the organ from the inside. Other types of stomach cancer are found much less frequently:
neuroendocrine tumors, etc.
A separate category should include diffuse stomach cancer, which is inherited. Infiltrative cancer affects the organ in different places, therefore it differs in that it does not have a clear localization.
Stages of stomach cancer
Depending on the degree of tissue damage and the spread of malignant cells, stomach cancer is divided into several stages:
Stage 1. It is characterized by a tumor that does not spread deeper than the submucosa.
Stage 2. The malignant neoplasm grows deeper and affects more lymph nodes.
Stage 3. It differs in that the tumor grows into the visceral peritoneum and adjacent organs.
Stage 4 stomach cancer. Separated metastases appear in the bones, ovaries, lungs, and other internal organs and tissues.
The main symptoms
At an early stage, the pathology may be asymptomatic. It can only be found by chance during gastroscopy. The first signs of stomach cancer are more like gastritis or peptic ulcer disease. The patient is usually worried about the following symptoms:
discomfort that increases after eating;
feeling of heaviness;
vomiting and nausea.
Stomach cancer pain usually occurs at a later stage. In addition, there is significant weight loss, lack of appetite and signs of intoxication – weakness, headaches, fatigue.
The most informative diagnostic method is considered to be gastroscopy and biopsy for stomach cancer (taking biological material for histological and cytological examination). If histology has confirmed the malignant origin of the tumor, the doctor prescribes a comprehensive study to determine the degree of damage to the tissues of the stomach and other organs.
Many patients are interested in whether stomach cancer is visible on ultrasound? The ultrasound method allows you to determine the boundaries of the tumor. On ultrasound, pathological cells are clearly visible, therefore this method can also be used to detect metastases in other organs.
The main treatment is surgery. Depending on the stage of the cancer, partial resection or gastrectomy (complete removal of the stomach) may be done. If the tumor is inoperable, palliative operations are performed:
gastric bypass surgery;
gastrostomy (gastrostomy is used for obstruction of the stomach and intestines).
In addition to surgery, treatment includes chemotherapy and radiation therapy. The drugs and radiation doses are selected individually for each patient. Symptomatic therapy and diet are also selected.
Complications and projections
The main complication of a tumor is its ability to metastasize. Malignant cells invade neighboring organs and spread along with the bloodstream throughout the body. Dangerous complications include gastric bleeding. Vomiting blood or black feces are obvious signs.
Our patients are interested in whether stomach cancer is curable. In the early stages, the pathology can be completely cured, but the main problem is that the tumor is usually found in the later stages.
Five-year survival rate for gastric cancer, depending on the degree of spread of metastases and the prescribed treatment, ranges from 12% to 30%. It is difficult to say how long stage 3-4 cancer lives, since it depends on where the tumor is located, whether it is possible to carry out surgery and other factors.
