Key clinical point: A >8-week interval between neoadjuvant chemoradiotherapy (nCRT) and subsequent surgery improved tumor regression grade (TRG) compared with a 6-8-week interval in patients with locally advanced rectal cancer (LARC), while pathological complete response (pCR) and survival outcomes were similar between the groups.
Major finding: The pCR rate (P = .836), 5-year relapse-free survival (P = .569), and 5-year overall survival (P = .956) were not significantly different between the 6-8-week and >8-week groups; however, TRG was significantly better in the >8-week group (P = .004).
Study details: Findings are from a retrospective study including 770 patients with LARC who had undergone total mesorectal excision either 6-8 weeks (n = 502) or >8 weeks (n = 268) after long‐course nCRT.
Disclosures: This study was supported by grants donated to Seoul National University Hospital under the name of Jung‐Ok Hwang. The authors declared no conflicts of interest.
