One Case of Metachronous Dual Primary Tumors

Abstract

This study is to explore the respects of a rare case of metachronous dual primary tumors like clinical characteristics, diagnostic methods, surgical treatment and chemotherapy strategies. The patient's first primary tumor was duodenal ampullary carcinoma at age 65, while the colon cancer was diagnosed 39 months later as the second primary tumor. The patient received treatments as pancreaticoduodenectomy, GS chemotherapy, and right hemicolectomy as well as XELOX chemotherapy. Follow-up of duodenal ampullary carcinoma has been 3 years and colon cancer has been 1 year after surgery. No sign of recurrence or metastasis has been found. The results of this study show that it is feasible to adopt an individualized comprehensive treatment strategy for patients with Metachronous Double Primary Tumors, which can offer a reference for similar cases.
