Impact of Interval between Neoadjuvant Chemoradiotherapy and TME for Locally Advanced Rectal Cancer on Pathologic Response and Oncologic Outcome

摘要

Background The interval between neoadjuvant chemoradiotherapy and surgery for rectal cancer has arbitrarily been set at 6–8 weeks. However, tumor regression is variable. This study aimed to evaluate whether the interval between neoadjuvant therapy and surgery had an impact on pathologic response and on surgical and oncologic outcome.
