Effects of Planned Stoma Before Neoadjuvant Chemoradiation in Patients With Endoscopically Obstructing Colorectal Cancer

PurposeIn order to investigate whether colorectal cancer (CRC) patients with endoscopic obstruction benefited from a planned stoma before neoadjuvant chemoradiation (nCRT).MethodsPatients who were diagnosed with CRC with endoscopic obstruction at a single clinical center from January 2017 to April 2022 were retrospectively collected. Baseline characteristics and short-term and long-term outcomes were compared between the stoma group and the no stoma group. Statistical analysis was performed using SPSS (version 22.0) software.ResultsA total of 51 CRC patients with endoscopic obstruction were included in this study. Eleven (21.6%) patients received a planned stoma before nCRT, and 40 (78.4%) patients were treated with immediate nCRT. The mean time from diagnosis to nCRT was 30.6 days for the stoma group and 11.9 days for the no stoma group. There was a significant delay in the initiation of nCRT in the stoma group (<i>P</i> < 0.05). In terms of complications, there was a statistical difference between the stoma group and the no stoma group (<i>P</i> < 0.05). Planned stoma before nCRT did not affect survival for patients with endoscopically obstructing CRC (<i>P</i> > 0.05).ConclusionA planned stoma caused delay in nCRT; the no stoma group was more likely to develop perforation or obstruction of the tumor during nCRT. A comprehensive assessment might be needed to determine whether a planned stoma was necessary in CRC patients with endoscopic obstruction.
