Pre-operative hyperfractionated concurrent radiochemotherapy for locally advanced rectal cancers: a phase II clinical study

摘要

Objective:The study was prospectively designed as a single-arm, single-institution prospective trial of pre-operative concomitant hyperfractionated radiotherapy (HART) with co-administration of chemotherapy based on 5-fluorouracil (5FU) in patients with T2/N+ or T3/any N resectable mid-low primary rectal cancer. The aim of the study was to assess the safety and efficacy of accelerated HART with concurrent 5FU-based chemotherapy in patients with locally advanced rectal cancer.
