Sexual dysfunction, informed consent and multimodality therapy for rectal cancer

This study assessed the presurgical and preradiation discussion of the risk of posttherapy sexual dysfunction among patients who underwent potentially curative therapy for rectal cancer. The incidence of sexual dysfunction after treatment for rectal cancer was then determined.

A retrospective review of the medical records of 52 consecutive patients who underwent potentially curative procedures for rectal cancer within 15 cm from the anal verge was performed.

Presurgical discussion of the risk of sexual dysfunction was not documented in the consent in 37 of 52 patients (71%). Among the 5 males who underwent local excision, none reported posttherapy sexual dysfunction. Of the 6 males who were treated by low anterior resection, only 1 had a postoperative complaint of sexual dysfunction. Five of 15 males (33%) treated with abdominoperineal resection (APR) alone reported postprocedure sexual dysfunction, whereas 6 of 8 males (75%) treated with APR and radiation reported dysfunction. Of the entire female cohort, only 1 of the 16 reported sexual dysfunction posttherapy.

A discussion of the risks of posttherapy sexual dysfunction was documented for fewer than one third of the patients. Among males after APR, the use of postoperative radiation showed a trend toward an increase in sexual dysfunction. Surgery and/or radiation therapy did not impact on sexual dysfunction in females.
