Prospective evaluation of quality of life of patients receiving either abdominoperineal resection or sphincter-preserving procedure for rectal cancer.

BACKGROUND: Study results on quality of life (QoL) between patients receiving an anterior resection (AR) or abdominoperineal resection (APR) for rectal cancer vary greatly. A main reason is grounded in unequal methodology. The aims of this study were to assess differences in perceived QoL over time among patients treated with AR or APR with a recommended study design and methodology.
METHODS: In a prospective study, the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire C30 and a tumor-specific module were administered to patients with rectal cancer before surgery, at discharge, and 3, 6, and 12 months after the operation. Comparisons were made between patients receiving an AR and those receiving an APR.
RESULTS: Two hundred forty-nine patients were included; 46 patients received an APR and 203 an AR. QoL data were available for 212 patients, of which 112 were female and 100 male. No differences in the distribution of age, sex, or tumor stage were observed between groups. EORTC function scales showed no significant differences, including body image scales, between patients receiving an AR and those receiving an APR. In symptom scores, AR patients had more difficulty with diarrhea and constipation, whereas patients with APR experienced more impaired sexuality and pain in the anoperineal region. At discharge, patients receiving an AR were more confident about their future.
CONCLUSIONS: QoL in patients receiving an AR and those receiving an APR is not different. Although patients with APR experience more impaired sexuality, patients receiving an AR experience decreases in QoL because of impaired bowel function.
