The survival period after chemotherapy for tumors should be judged comprehensively according to the patient’s specific situation, which is related to the pathological stage of the tumor, the treatment mode, and the patient’s condition after receiving the treatment. Early stage patients can even reach the level of cure through chemotherapy. The survival rate of 5 years is higher for intermediate stage patients, and the survival time of late stage patients can also be prolonged to a certain extent after active treatment.1. Early stage patients: For patients with early detection, such as choriocarcinoma, germ cell tumors, and some tumors that are more sensitive to chemotherapy, such as spermatocellular carcinoma and choriocarcinoma, the survival time can be 10-15 years or even longer with active treatment after clear indications for chemotherapy. If the level of cure can be achieved, life expectancy may not be affected; 2. Intermediate stage patients: For intermediate stage patients, after active chemotherapy may control the deterioration of tumor development and improve patients’ quality of life, survival time can generally reach more than 5 years; 3. Advanced stage patients: For advanced stage patients, with less differentiated tumor and greater metastasis, chemotherapy and other means can be used to try to relieve patients’ symptoms, and when the effect is better Survival time can be about 3 years. However, for patients with advanced liver cancer and pancreatic cancer, the effect is not obvious after treatment, and the survival period may only be a few months. For patients with advanced cancer, the main purpose of treatment is to control the tumor and prolong the survival period, so the process should take into account the tumor and patient tolerance, so that patients can obtain a high quality of life and prolong their survival time as much as possible. For tumor prevention is better than cure, one should develop good living habits, regular medical checkups, try to achieve early detection, early diagnosis and early treatment to avoid serious deterioration, which will affect patients’ life as well as survival quality.
