The treatment effect of advanced cancer itself is not good, and if there is extensive spread, most of the survival time is not long, maybe three months to six months or a little longer, but more than one year or two years is still rare. Of course, it also depends on the treatment. In some cases, the spread of cancer is controlled after treatment, and the primary lesion is not widely developed, so the treatment effect may be better and the survival time may be longer. Generally, local radiotherapy, systemic chemotherapy and targeted therapy are needed, like advanced inoperable gastric cancer and malignant tumors in the combined esophagus and stomach, which can be treated with the targeted drug Apatinib, which can significantly prolong survival if it works. There are clinical reports of patients surviving more than three or five years, but it is not easy to determine exactly how long they can live, and we can only see while treating them.
