Title
Adjuvant radiotherapy for rectal cancer: a systematic overview of 8,507 patients from 22 randomised trials.
Authors
Colorectal Cancer Collaborative Group
Abstract
At least 28 randomised, controlled trials have compared outcomes of surgery for rectal cancer combined with preoperative or postoperative radiotherapy with those of surgery alone. We have done a collaborative meta-analysis of these results to give a more balanced view of the total evidence and to increase statistical precision.
