Efficacy and toxicities of gemcitabine and cisplatin combined with endostar in advanced thymoma and thymic carcinoma: GP + endostar in advanced thymic tumors

Background Thymoma and thymic carcinoma are rare thymic epithelial tumors. We investigated the efficacy of first‐line gemcitabine and cisplatin (GP) chemotherapy versus gemcitabine and cisplatin chemotherapy combined with the anti‐angiogenic drug endostar (GP + E) in advanced thymoma and thymic carcinoma.
