Prehabilitation is a multi-modal, preoperative optimization program with nutritional optimization and weight loss as core principles, reported to reduce complications after major cancer surgery. Weight-loss-focused prehabilitation may apply to patients with an-above normal BMI with a sufficient preoperative intervention window, such as a period of neoadjuvant chemotherapy. Our study objectives are to compare complication rates between BMI categories and identify an optimum BMI target for patients with an above-normal BMI to aim for during prehabilitation to modify their risk of perioperative morbidity. METHODS: Data were extracted from the Canadian Bladder Cancer Information System (CBCIS), a prospective Canadian registry across 13 academic centers. A retrospective analysis was performed on 589 patients who underwent RC. Peri-operative (≤90 days) complications were classified by type and severity according to Clavien-Dindo classification (CDC), where available. Unconditional Logistic regression analysis was performed to determine the association between BMI and complication risk. RESULTS: The median BMI of the cohort was 27 (IQR 7), with 29% classified as having normal BMI (<25 kg/m2), 38% overweight (25-29), 21% Class I (30-35), and 12% ≥ Class II (>35) obesity. The overall complication rate was 40%. Complication detection was highest in the overweight group. Intra-operative blood loss and length of hospital stay were significantly increased in all above-normal BMI groups. Ileus, wound infection and urine leak were the most commonly detected postoperative complications. On multivariable analysis, overweight BMI was independently associated with any complications (OR 1.96, p=0.004) and urine leak (OR 5.22, p=0.034), ≥ Class II obesity BMI was associated with any complications (OR 3.49, p<0.0001), wound infection (OR 6.31, p<0.0001), fascial dehiscence (OR 5.57, p=0.027) and urine leak (OR 5.69, p=0.044). The Class 1 obesity group was not significantly associated with complications (OR 1.38, p=0.259). CONCLUSIONS: This study demonstrates the feasibility of utilizing a national bladder cancer database to record and evaluate RC complications. Overweight and Class II obesity BMI groups were significantly associated with perioperative morbidity. These groups may benefit from a targeted weight-loss intervention during prehabilitation, where feasible, to reduce risk of perioperative morbidity following RC.
