摘要

Abstract Aim The aim was to determine whether the addition of additional cycles of chemotherapy during the ‘wait period’ following neoadjuvant chemoradiotherapy for rectal cancer improves the pathological complete response ( pCR ) rate. Method Rectal cancer patients were randomly allocated either to a standard 10?week wait period before surgery (standard chemoradiotherapy, SCRT ) or to receive three cycles of fluorouracil based chemotherapy following chemoradiotherapy during a similar 10?week wait (extended chemoradiotherapy, XCRT ). The primary end‐point was pCR as determined by blinded pathological assessment. Results Forty‐nine patients were randomized ( SCRT n? = ? 24, XCRT n? = ? 25). pCR occurred in 10 patients overall but there was no significant difference in pCR between the groups ( SCRT n? = ? 6, XCRT n? = ? 4, P? = ? 0.49). Conclusion The addition of three cycles of 5‐fluorouracil/leucovorin in a 10?week wait period after conventional chemoradiotherapy seems to result in similar pCR rates in patients with locally advanced rectal cancer based on this small randomized trial.
