Better quality of life and reduced fecal incontinence in rectal cancer patients with the watch-and-wait follow-up strategy.

INTRODUCTION

The watch-and-wait (WW) strategy is an alternative to anterior resection in patients with rectal cancer (RC) that have had a complete clinical response to neoadjuvant treatment. Few reports describe the quality of life and functional anorectal disorders (FADs) in that population.

AIM: To analyze and compare the FADs and quality of life in patients with locally advanced adenocarcinoma of the rectum treated with neoadjuvant therapy, divided into two different strategy groups: group 1 (G1), WW; and group 2 (G2), anterior resection.

MATERIALS AND

METHODS

Thirty patients (G1: n = 20 and G2: n = 10) that had finished neoadjuvant therapy at least 12 months prior were included. Mean patient age was 59.5 years (range: 41-79) and 15 of the patients were men. The FADs were evaluated through: a) clinical history, b) 21-day bowel diary, c) Jorge and Wexner fecal incontinence scale, d) anorectal manometry (ARM), and fecal incontinence quality of life scale (FIQL).

RESULTS

Bowel diary: fecal incontinence (40%) and urge to defecate (45%) in G1 vs. fecal incontinence (60%) and urge to defecate (30%) in G2, with no significant differences (p = NS). Fecal incontinence scale: fecal incontinence in G1 was significantly less severe than that in G2 (median 6.5 points vs. 13 points [p = 0.0142]). ARM: no differences between the two groups. Quality of life: significantly different between the two groups (FIQL/G1: 3.7 vs. FIQL/G2: 2.8; p < 0.03).

CONCLUSIONS

The WW follow-up strategy in patients with locally advanced rectal cancer was associated with better quality of life and reduced fecal incontinence.
