Abstract
AIM
To ascertain the degree of adherence to the guideline recommendation on pre-operative RT/ChT for stage-II and -III patients in Catalonian public hospitals, and its impact on local recurrence among rectal cancer patients.
METHODS
Data were derived from a multicentre retrospective cohort study of patients who underwent curative-intent surgery for primary rectal cancer at Catalonian public hospitals in 2005 and 2007.
RESULTS
The study covered 1229 patients with TNM stage-II or -III primary rectal cancer. Of these patients, 54.5% underwent pre-operative RT/ChT; 14.9% underwent post-operative RT (± chemotherapy); and 30.6% did not undergo any RT. The crude local recurrence rate at 2years was 4.1% and the crude distant recurrence rate at 2years was 6.5%. The results of the univariate analyses showed a local-recurrence hazard ratio of 1.84 for the group of patients that received no RT versus the group that received pre-operative RT/ChT (p<0.01).
CONCLUSIONS
This is the first population-based study in Catalonia to support the use of pre-operative RT/ChT in rectal cancer patients because, in line with the results of population-based studies reported from other countries, its application, compared to non-application of RT, was found to lead to a clear reduction in the probability of local recurrence.
