摘要: Objective: An increasing number of patients with locally advanced gastric carcinomas (GC) are being treated with preoperative chemotherapy before surgery. Background: Histopathological tumor regression may have an important prognostic impact in addition to the UICC-TNM classification system. Methods: We evaluated the histopathological tumor regression in 480 surgical resection specimens of GC after neoadjuvant cisplatin-based chemotherapy, using an established system encompassing three tumor regression grades …
