Survival time of liver cancer wasting can not be determined. Survival time is mostly related to tumor staging, physical condition and treatment methods. 1. Tumor staging: Early liver cancer patients who receive radical surgery have better prognosis and the 5-year survival rate can reach 40% to 70%. The survival time of advanced liver cancer is only half a year to one and a half years. 2. Physical condition: those who are in good physical condition will have longer survival time, while those who are in poor physical condition or accompanied by other basic diseases, such as coronary heart disease, chronic obstructive pulmonary disease, etc., will have relatively shorter survival time. 3. Treatment: Liver cancer is not sensitive to chemotherapy and radiotherapy, and surgical treatment is the most important means for long-term survival, including hepatectomy and liver transplantation. At present, targeted therapy and immunotherapy have better efficacy on liver cancer, including sorafenib, lenvatinib, atilizumab, etc., which can prolong the survival period of patients to a certain extent. Liver cancer patients need to pay attention to reasonable diet and nutrition. After remission by treatment, they should follow up and observe in time, and can receive timely treatment for early detection of recurrence and metastasis, which can improve the prognosis.
