RESULTS: Of 2572 patients undergoing rectal cancer surgery in 277 participating centres across 44 countries, 673 (26.2%) underwent chemoradiotherapy and surgery. (lu.se)

INTRODUCTION: The mainstay of management for locally advanced rectal cancer is chemoradiotherapy followed by surgical resection. (lu.se)
BACKGROUND: Preoperative radiotherapy (PRT) has become part of standard practice offered to improve treatment outcomes in patients with rectal cancer. (mcmaster.ca)
OBJECTIVES: To determine if PRT improves outcome for patients with localized resectable rectal cancer and how it compared with other adjuvant or neoadjuvant strategies. (mcmaster.ca)
SEARCH STRATEGY: A computerized search was performed December 2006 on MEDLINE (from 1966 to December 2006) and the Cochrane Central Register of Controlled Trials (CENTRAL), conference proceedings, using MeSH and textwords where appropriate to identify randomized trials in PRT and rectal cancer.

Reacting to the findings, Pamela Kunz, MD, leader of the Gastrointestinal Cancers Program at Yale Cancer Center, New Haven, Connecticut, commented: "What's important here is that radiation can be safely omitted in many patients with clinically advanced rectal cancer - this is really 'less is more. (medscape.com)
Marijnen also pointed out that the definition of "locally advanced" in rectal cancer varies by region, and that in Europe many of the patients in the current trial would be defined as early and intermediate stage, and so would not qualify for neoadjuvant therapy. (medscape.com)
