The maximum number of years a patient can live with plasma cell tumor is mainly related to the treatment and individual patient factors, which should be analyzed on a case-by-case basis and should not be generalized. Plasma cell tumor is a slow progressing tumor, and the tumor cells are relatively inert and responsive to treatment. If the patient is in good health, the survival time is longer with active treatment after early detection, generally more than 5-10 years, but the maximum survival time varies from person to person. In addition, plasmacytoma is a malignant tumor that is not clinically curable and requires long-term medication to control the tumor. If patients have a poor prognosis, serious complications can occur and survival time is usually 1-3 months. Therefore, patients with plasmacytoma should go to regular hospital medical oncology department in time, and professional doctors should formulate rationalized treatment plan according to patients’ specific conditions in order to prolong survival time.
