title: A clinicopathological analysis of 22 cases of multiple malignant tumors.
abstract: To get a better understanding of the location, pathophysiology, etiology and prognosis of multiple malignant tumors (MPMT), we evaluated the medical records of 22 patients with MPMT. Our results suggested that radiotherapy and chemotherapy might play an important role in the pathogenesis of MPMT and follow-up is important in detecting a secondary primary malignant tumor (PMT) at an early stage. Surgical removal of tumors is the first-choice therapy for MPMT.
