Comparison of efficacy for postoperative chemotherapy and concurrent radiochemotherapy in patients with IIIA-pN2 non-small cell lung cancer: an early closed randomized controlled trial.

Objective: The efficacy of postoperative concurrent radiochemotherapy (POCRT) on IIIA-pN2 non-small cell lung cancer (NSCLC) is still unclear. The aim of this randomized controlled trial was to compare POCRT with postoperative chemotherapy (POCT) alone in terms of survival and relapse patterns.

Methods: Patients with completely resected IIIA-pN2 NSCLC were randomized into POCRT or POCT groups.

A randomized, controlled, multicenter study comparing intensity-modulated radiotherapy plus concurrent chemotherapy with chemotherapy alone in gastric cancer patients with D2 resection.

Background And Purpose: The role of postoperative chemoradiotherapy in the treatment of patients with gastric cancer with D2 lymph node curative dissection is not well established. In this study, we compared postoperative intensity-modulated radiotherapy plus chemotherapy (IMRT-C) with chemotherapy-only in this patient population.

Materials And Methods: We randomly assigned patients with D2 lymph node dissection in gastric cancer to IMRT-C or chemotherapy-only groups.
