Research progress of prognostic evaluation in thymoma

Thymoma is the most common primary malignant tumor which occurs in the anterior mediastinum. The incidence of thymoma is relatively low with scarce large sample and multicenter studies available on the prognostic factors of these patients, and the related indexes for evaluating the prognosis are still under investigation. Looking for possible predictive indicators for prognosis evaluation, we can grasp the initiative of diagnosis, seize the opportunity of treatment, and intervene in the poor prognostic factors, thereby improving the prognosis of patients.
