Study information

Scientific title

Acronym

BRCT (Berlin Rectal Cancer Trial)

Study hypothesis

Standard treatment for locally advanced cancer of the rectum is pre-operative short-course radiotherapy or combined neoadjuvant radiochemotherapy with 5-fluorouracil (5-FU) plus post-operative chemotherapy with 5-FU. Similar long-term survival, local control and late morbidity have been reported for both these methods in non-comparative studies. In addition to other ongoing comparative trials we include a larger number of patients for adequate power and we avoid the adjuvant treatment bias by mandatory adjuvant chemotherapy in both groups. It is our hypothesis that the rate of local recurrence after five years is 12% in pre-operative short-course radiotherapy and 7% in combined radiochemotherapy.

Ethics approval

Approved by the Ethics Committee of the Charité and the responsible authorities. Certified and recommended by the German Gancer Society ("Gütesiegel A") on the 29th September 2003 (ref: AA3/03/38; EudraCT-number: 2004-001606-27).
