[Application value of colonoscopic assessment in "watch and wait" strategy for mid-lower rectal cancer after neoadjuvant chemoradiotherapy].
Objective: To investigate the value of colonoscopic assessment in "watch and wait" strategy for mid-lower rectal cancer after neoadjuvant chemoradiotherapy (nCRT). Methods: A single-center retrospective case series study was performed. Database of mid-lower rectal cancer patients at Department of Gastrointestinal Oncology, Peking University Cancer Hospital & Institute from March 2011 to June 2017 was retrieved. ⋯ Meanwhile lateral developmental tumor of ascending colon in 1 case and of sigmoid in a case was found by colonoscopy and confirmed as HIN by postoperative pathology. Besides, 4 cases developed colonic multiple adenoma and all underwent endoscopic resection. Conclusion: Colonoscopy examination plays an important role in both initial assessment and regrowth monitoring during watch and wait strategy after nCRT treatment.
