Summary
Brief summary (as posted)
Background Neoadjuvant chemoradiotherapy (NCRT) and total mesorectal excision are standard treatments for patients with locally advanced rectal cancer. These sphincter-saving operations may be accompanied by a series of functional disorders. Prospective studies dynamically evaluating the different roles of surgery and NCRT on anorectal function are lacking. Methods/design The study is a prospective, observational, controlled, multicentre study. After screening for eligibility and obtaining informed consent, a total of 402 rectal cancer patients aged from 18 to 75 years old undergoing sphincter preservation treatments at The Sixth Affiliated Hospital, Sun Yat-sen University and Nanfang Hospital, Southern Medical University are included in the trial. The primary outcome measure is the average resting pressure of anal sphincter. The secondary outcome measures are maximum anal sphincter contraction pressure and Wexner continence score. Evaluations will be carried out at the following stages: baseline (T1), after radiotherapy or chemotherapy (before surgery, T2), after surgery (before closing the temporary stoma, T3), and at follow-up visits (every 3 to 6 months, T4, T5……). Follow-up for each patient will be at least 2 years. Discussion We expect the program to provide more information on therapeutical options and strategies to reduce anorectal dysfunction of rectal cancer patients who have been undergone sphincter preservation treatments.
