The RAPIDO trial-Reduction in disease-related treatment failure does not translate into improved overall survival: a mystery solved!

The initial publication of the RAPIDO trial resulted in widespread adoption of short-course radiotherapy and consolidation chemotherapy in locally advanced rectal cancer. The impressive reduction in disease-related treatment failure did not, however, translate into any overall survival benefit. The recent update of the RAPIDO trial with its 5-year results provides much insight into the actual effect that this approach has on patient outcomes and the detriment in local control leads to the question as to whether this approach can still be considered as standard of care in high-risk rectal cancer.
