Stomach cancer is a malignant tumor that occurs in the stomach tissues. Most tumors are formed from the inner layer (stomach lining), which normally produces mucus and gastric juice. These tumors are called adenocarcinomas, and they account for about 90% of all gastric malignancies.
Stomach cancer overview
Stomach cancer can occur in various parts of the organ – in part of the junction of the esophagus and stomach, in the fundus of the stomach, in its body, and in its outlet. Depending on the location of the tumor, different symptoms occur.
A tumor in the stomach can interfere with digestion, i.e. prevent food from passing into the lower parts of the digestive tract. A cancerous tumor growing into the wall of the stomach can spread to other organs – to grow into the colon and pancreas. When a tumor is located near the esophagus, it can disrupt the passage of food into the stomach. As a result of all this, weight loss occurs followed by physical exhaustion. The tumor can spread through the lymphatic and blood vessels to other organs (liver, lungs, brain, bones, etc.).
Causes
The leading oncologists around the world are looking for the answer to the question of what causes stomach cancer. The reliable causes of malignant neoplasms of the stomach development have not been identified yet. However, to date, the conditions that are connected with the development of cancer cells in the gastric mucosa are well studied.
As with other malignant neoplasms, there is no one specific cause or predisposing medical factor that leads to the development of stomach cancer.
Nutrition is of great importance. Excessive consumption of starchy foods, poor with fresh vegetables and fruits diet, a lack of animal protein and an excess of animal fats contribute to the development of the disease. A negative role is played by alcohol abuse, smoking, irregular eating, improper chewing of food.
Undoubtedly, the presence of chronic stomach diseases plays an important role. With the chronic inflammatory process in the gastric mucosa (chronic gastritis), in the presence of gastroduodenal reflux, when the contents of the duodenum and bile are thrown back into the stomach, the background for the growth of malignant tumors is created. Often polyps transform into stomach cancer. Therefore, timely treatment of these diseases is of high importance in the prevention of stomach cancer.
Symptoms
Stomach cancer has no significant symptoms at its early stages. Signs of stomach cancer may be mistaken for other diseases, such as gastritis. Usually an exacerbation of gastritis leads few people to a doctor’s office. Unpleasant sensations are removed with available medicines and patients hope that the health condition will improve. If the patient notices that he is getting tired quickly, has lost weight, and is constantly experiencing discomfort in the stomach, the patient should consult an oncologist.
The manifestations of advanced stomach cancer depend on the location of the tumor. If it is located in the upper section, where the esophagus enters the stomach, then dysphagia (difficulty swallowing) appears. If the tumor is located in the lower part of the stomach, vomiting with the food that has just been eaten can occur. Also, severe heartburn and abdominal pain that does not go away become constant.
Even if it seems that "it hurts slightly", or "you have to be patient, and it will go away", do not take risks. If you experience the following symptoms, immediately consult a doctor:
- Fatigue
- Severe unintentional weight loss
- Constant discomfort in the stomach and abdomen
- Difficulty swallowing food
- Constant abdominal pain
- Frequent vomiting
- Constant severe heartburn
Diagnostics
A patient with suspected stomach cancer should undergo diagnostic tests, both laboratory and instrumental ones.
The EGD is an endoscopic procedure that is usually prescribed for the diagnosis of gastric oncology. To examine the insides of the organ, the doctor uses a flexible tube with a high-resolution video camera. The video is displayed on the screen in real-time. If during the examination the doctor sees pathological changes in the walls of the stomach, then he takes samples of suspicious tissues for further laboratory analysis.
In addition to the endoscopic examination, radiography with a contrast agent, laparoscopic diagnostics, and various types of tomography are used to confirm the diagnosis. Computed tomography and MRI for stomach cancer allow specialists to receive a comprehensive picture of the disease development and to detect metastases. During positron emission computed tomography (PET CT) the doctor receives information about cancer cells at the molecular level.
Based on the research results obtained, the team of the oncologists elaborates the further tactics of treating the patient.
Treatment
The main and practically the only method of radical treatment of stomach cancer is surgery. However, despite the improvement of surgical techniques, the prognosis of surgery in patients with advanced stomach cancer remains unsatisfactory. As shown by the multivariate analysis in surgical oncology among patients operated on for stomach cancer, independent risk factors for cancer recurrence are an undifferentiated tumor type and affection of the serous membrane of the stomach that is inefficiently treated with surgery.
In the last 15 years, interest in the effectiveness of intraperitoneal administration of chemotherapy drugs for stomach cancer treatment has increased. As a result, the use of hyperthermic intraperitoneal chemotherapy HIPEC has become widespread.
Hyperthermic intraperitoneal chemotherapy (HIPEC) aims to affect macro- and microscopic metastases, as well as free tumor cells in the peritoneal fluid. Hyperthermic intraperitoneal chemotherapy (HIPEC) is indicated not only for palliative surgery procedures, but also for all cases of detection of tumor cells inside the abdominal cavity. A number of specialists in surgical oncology expand the indications, considering it suitable for the treatment of stomach cancer with affection of the serous membrane of the stomach.
The HIPEC procedure can be divided into intraoperative and postoperative one. Hyperthermic intraperitoneal chemotherapy (HIPEC) was initially used in the form of a single injection of a chemotherapy drug into the abdominal cavity at the final stage of the surgery. Then intraperitoneal administration of chemotherapy drugs began to be used in the postoperative period, in the form of multi-day courses. Now, many specialists in surgical oncology consider the administration of drugs during surgery in combination with hyperthermia the most effective method of stomach cancer treatment. For a longer and more uniform flow of chemotherapy drugs into the abdominal cavity, special anticancer drugs have been created for HIPEC.
Currently, HIPEC is rarely performed with a single drug. The advantage of polychemotherapy is confirmed by different studies in surgical oncology. Patients who were operated for stomach cancer with further administration of the heated chemotherapy drugs have shown the best survival rates.
In surgical oncology, some doctors practice the combination of HIPEC and systemic chemotherapy for stomach cancer treatment. Among patients who had metastatic lesions of the peritoneum, a significant improvement in survival was noted in the case of combining HIPEC and systemic chemotherapy.
A surgical oncology practice indicates low toxicity of HIPEC along with the possibility of obtaining a positive effect of treatment of stomach cancer patients with its help. Some studies show the relatively long survival of stomach cancer patients who were treated with HIPEC.
