How long an elderly person can live with leukemia is closely related to the type of leukemia they have, the treatment they take, and their condition, as they can have many types of leukemia, including acute leukemia, chronic granulocytic leukemia, and chronic lymphocytic leukemia, all of which have different clinical characteristics and significantly different patient survival periods. If an elderly person has acute leukemia, the survival period for the elderly is often no more than about 2-3 years because the elderly patient cannot tolerate conventional doses of chemotherapy and can only be given small doses of chemotherapy or symptomatic treatment. If an elderly person has chronic lymphocytic leukemia, which is the most common type of leukemia in elderly patients, some elderly patients can survive for about 5-10 years even if they are not given any treatment and only have regular clinical observation. Some elderly people who have chronic granulocytic leukemia can also survive for about 5-10 years by taking drugs such as Gleevec. Therefore, when an elderly person has leukemia, it depends on the type of leukemia and then according to different treatments, so that you can roughly project the survival period of an elderly person after getting leukemia.
