Community-based prehabilitation in older patients and high-risk patients undergoing colorectal cancer surgery

Abstract

IntroductionPrehabilitation before colorectal cancer (CRC) surgery is promising to prevent complications and to enhance recovery, especially in patients aged 70 or older or in patients with an American Society of Anaesthesiologist (ASA) physical classification score 3–4, for whom surgery is associated with higher postoperative complications and long-lasting adverse effects on functional performance. Materials and methodsA cohort study was conducted in a large teaching hospital in Alkmaar, the Netherlands. Fifty CRC patients (≥70 years or ASA 3–4) underwent multimodal prehabilitation between September 2020 and July 2021. The reference group comprised 50 patients (≥70 years or ASA 3–4) from a historical cohort receiving CRC surgery without prehabilitation (March 2020–August 2020). The primary outcome was 90-day postoperative complication rate. Secondary outcomes were length of stay, 90-day readmission and mortality rates and functional outcome in the prehabilitation group. ResultsOne patient in the prehabilitation group decided not to undergo surgery. Of the remaining 49 patients, 48 (98.0 %) received prehabilitation for at least 3 weeks. Of these patients, 32.7 % developed postoperative complications, compared to 58 % in the reference group (p = 0.015), and none were readmitted, in contrast to 6 reference group patients (12.0 %, p = 0.012). Length of stay and mortality did not differ significantly. Six weeks postoperatively, all functional outcomes in the prehabilitation group were significantly higher than at baseline. ConclusionsPrehabilitation reduced postoperative complications and improved short-term functional outcomes in older and high-risk patients receiving CRC surgery. Further research should investigate the maintenance of long-term enhanced lifestyle and the effects of tailor-made programs.
