Sphincter-saving surgery versus abdominoperineal resection in low rectal cancer following neoadjuvant treatment with propensity score analysis

Sphincter-saving operation is the treatment of choice in patients with lower rectal cancer, although abdominoperineal resection (APR) is necessary in some cases for adequate oncological outcomes. This study compared the oncologic outcomes of patients with low rectal cancer undergoing APR and intersphincteric resection (ISR) after neoadjuvant chemoradiotherapy (nCRT).We compared 104 patients who underwent ISR for lower rectal cancer between 2008...
