Cheng YK, Qin QY, Huang XY, et al. - In this cohort study from a phase III, randomized controlled trial, surgery was done in 60 individuals following an interval of ≤ 7 weeks and in 97 people following an interval of > 7 weeks in order to assess the impact of the interval between chemoradiotherapy (CRT) and surgery on radiation proctitis, the pathologic response, and postoperative morbidity. This study found that a more prolonged period following CRT could be correlated with a greater rate of radiation proctitis and more extended operation time. Moreover, it did not raise the rate of pathologic complete remission.
