The exact survival time of invasive thymoma is uncertain and is generally closely correlated with the patient’s clinical stage. Early-stage patients generally have a longer survival period, with a five-year survival rate that can reach about 80%, while late-stage patients have a shorter survival period, in some cases only a few months. Thymoma is a common tumor lesion in the mediastinum, and the survival time of patients with clinically aggressive thymoma is generally closely related to the patient’s stage, and the earlier the stage, the longer the patient’s survival time. Studies have confirmed that the five-year survival rate of early-stage invasive thymoma patients who can undergo radical surgery can reach about 80%, and cured patients can survive for a longer period of time. In contrast, late-stage patients who are not able to undergo radical surgery have their survival significantly shortened to a few months.
