Background: The Meta-Analysis of Radiotherapy in squamous cell Carcinomas of Head and neck (MARCH) showed that altered fractionation radiotherapy is associated with improved overall and progression-free survival compared with conventional radiotherapy, with hyperfractionated radiotherapy showing the greatest benefit. This update aims to confirm and explain the superiority of hyperfractionated radiotherapy over other altered fractionation radiotherapy regimens and to assess the benefit of altered fractionation within the context of concomitant chemotherapy with the inclusion of new trials.

Methods: For this updated meta-analysis, we searched bibliography databases, trials registries, and meeting proceedings for published or unpublished randomised trials done between Jan 1, 2009, and July 15, 2015, comparing primary or postoperative conventional fractionation radiotherapy versus altered fractionation radiotherapy (comparison 1) or conventional fractionation radiotherapy plus concomitant chemotherapy versus altered fractionation radiotherapy alone (comparison 2).

Background: The improvement in surgical techniques alongside neoadjuvant chemoradiation enabled more patients with low rectal cancer to have sphincter preservation.

Study Aim: To compare the oncologic and functional outcome in patients with locally advanced low rectal cancer treated by neoadjuvant chemoradiation followed by sphincter saving resection (SSR) against those who underwent abdomino-perineal resection (APR).

Patients And Methods: A total of 111 patients with low rectal cancer were included in the study.
