Generally speaking, liver cancer patients undergoing liver replacement surgery have different conditions, and the length of survival period varies, the most important thing depends on the degree of liver disease before liver replacement. However, it also depends on the patient’s age, physical condition, whether he has other chronic diseases, whether he has bad living habits and eating habits, alcohol consumption, overeating, psychological state and other factors. The effect of liver transplantation is not too good if it is done in the middle and late stages of liver cancer, because in this period, patients may have metastasis, so it is not very meaningful to replace the liver.
