How to treat advanced malignant gastric cancer
summary
China is a country with high incidence of gastric cancer, which is also famous in the world, and the number of gastric cancer patients is increasing every year. In China, the incidence of gastric cancer is not only high, but also its mortality rate is quite high. About 170000 patients die of gastric cancer every year, occupying the "dominant" position in the number of malignant deaths. Is it because gastric cancer can't be treated? The answer is no, gastric cancer can be treated, but it is difficult to cure. So how to treat early gastric cancer? How to treat advanced gastric cancer?
How to treat advanced malignant gastric cancer
First: radiotherapy for undifferentiated carcinoma, poorly differentiated carcinoma, tubular adenocarcinoma and papillary adenocarcinoma has certain sensitivity to radiotherapy, and the effect is best for small and shallow tumor foci and no ulcer, which can make the tumor disappear completely. Mucinous adenocarcinoma and signet ring cell carcinoma are not effective to radiotherapy, so they are contraindications. Preoperative radiotherapy for gastric cancer can make more than 60% of the patients have different degrees of primary tumor regression, the resection rate is 5.3% - 20% higher than that of the simple operation group, and the 5-year survival rate can be increased by 11.9%. Intraoperative radiotherapy is recommended for patients with primary tumor resection, lymph node metastasis within two groups, or primary tumor invasion of serosal surface and involvement of pancreas, without peritoneal and liver metastasis. For those who can not be resected during operation, the residual cancer should be marked with silver pods. Postoperative pathology confirmed that the histological type is not mucinous carcinoma or signet ring cell carcinoma. Postoperative supplementary radiotherapy is feasible.
The second is surgical treatment. If there are no obvious signs of metastasis in clinical examination, no serious organic lesions in important organs, and the nutritional status and immune function of the whole body are estimated to be able to tolerate surgery, laparotomy should be performed. Sometimes, even if there are distant metastasis, pyloric obstruction, perforation and other serious complications, but generally can tolerate surgery, palliative surgery should also be given to relieve symptoms and pain. The effect of surgical treatment of gastric cancer is closely related to the early diagnosis, pathological morphology and the choice of surgical scheme. According to the research on the biological behavior of gastric cancer, the prognosis of upper gastric cancer is worse than that of middle and lower gastric cancer, because the patients with middle and lower gastric cancer are more likely to live in groups, while the patients with upper gastric cancer are more likely to die. The size of the tumor has no significant relationship with the prognosis. Because of its unclear margin, it is difficult to determine the extent of surgical resection, and this type of gastric cancer has a wide range of metastases, so it is not easy to remove completely. Therefore, the annual survival rate is low. The perigastric lymph nodes of group type gastric cancer are mostly mild metastasis and located near the cancer focus, so the operation is easy to remove completely, so the prognosis is good. In the past 30 years, the 5-year survival rate of gastric cancer is between 20% and 30%.
Third: Traditional Chinese medicine treatment: Traditional Chinese medicine treatment of tumor often take the blood stasis, soft and hard Sanjie, heat clearing and detoxification, Fuzheng Guben drugs, in the treatment of malignant tumor, especially in the treatment of advanced malignant tumor, the curative effect is remarkable, the advantage of advanced gastric cancer treatment of traditional Chinese medicine is strong integrity, can make up for the lack of surgery, radiotherapy and chemotherapy and other treatment and small side effects, etc.
matters needing attention
Advanced gastric cancer, some patients can not be treated by surgery, can be treated by chemotherapy, traditional Chinese medicine, or combination of traditional Chinese and Western medicine, can reduce the pain of patients, but also produce therapeutic effect. For patients with advanced gastric cancer, the treatment is more difficult. Because they have a greater psychological burden, the fear of advanced cancer often makes them doubt the treatment or produce negative emotions, which has a great impact on the treatment effect and is not conducive to the development of the disease. Therefore, the relatives of patients with advanced gastric cancer during the treatment of patients, to more enlighten the patient's mood, try to make the patient emotional stability, positive and optimistic, good cooperation with the doctor for treatment, to maximize the therapeutic effect.
