Gastric cancer is divided into 4 clinical stages according to the depth of primary tumor infiltration into the stomach wall, lymph node metastasis and distant metastasis, which are the three bases. Usually, T4 stage gastric cancer indicates that cancer cells have metastasized, and the survival rate of 5 years at this time does not exceed 20-30%. If metastasis occurs but can be treated surgically, it is recommended that timely surgical treatment should be performed to control the aggravation of the disease, which can improve the survival rate after surgery. However, after surgery, chemotherapy should be continued on a regular basis. It is recommended to choose the combination of chemotherapy and traditional Chinese medicine because chemotherapy will bring certain pain to patients, and the toxic side effects of chemotherapy drugs can be reduced through traditional Chinese medicine treatment, thus relieving patients’ pain. For the survival rate of T4 gastric cancer, besides the surgical treatment, it is also related to one’s own resistance and whether one can combine with other physical diseases, for example, older people may also combine with cardiovascular diseases such as hypertension and hyperlipidemia, and their survival rate will be greatly reduced. However, for younger tumor patients under 30 years old, their tumors are more malignant and their survival time will be reduced.
