Impact of histopathology on the outcome of D1/D2 gastrectomies with R0 resection.

Aims: The primary objective of this study was to clarify the influence of histotype on the outcome of D1/D2 gastrectomized patients with pathologically proven R0 resection. The secondary objective was to demonstrate overall survival (OS), disease-free survival (DFS), and locoregional recurrence rates following standard curative surgery.

Patients And Methods: All patients had either pure signet-ring cell carcinoma (SRCC)/poorly differentiated adenocarcinoma (PDC) or moderately differentiated adenocarcinoma (MDC) of the stomach, preoperative radiologic evidence of locoregional disease, and no history of neoadjuvant therapy.

Longitudinal surveillance of mid- and distal rectum cancer in a subset of patients with specific histology.

Objective: A prospective study in 82 consecutive patients with mid- and distal rectal adenocarcinomas having specific histology and tumor stage was conducted to asses impact of curative surgery.

Methods: Patients with moderately differentiated adenocarcinoma (MDAC) with or without mucinous differentiation underwent curative resection. Forty patients were in Stage B1-B2 and 42 patients were in Stage C1-C2.
