To determine the effect of preoperative nutrition and multimodal prehabilitation on clinical and functional outcomes in surgical lung cancer patients. We searched MEDLINE, Cochrane Library and CENTRAL, EMBASE, Scopus, and clinical trial registries ( clinicaltrials.gov , International Clinical Trials Registry Platform and Google Scholar) to identify studies involving a preoperative nutrition-based intervention or multimodal prehabilitation (nutrition with exercise) of at least 7 days, in lung cancer patients awaiting surgery. Studies must have reported results on at least one of the following outcomes: functional capacity, pulmonary function, postoperative complications, and length of hospital stay. The quality of included studies was assessed using the Cochrane risk of bias assessment tool for randomized trials and the modified Newcastle-Ottawa scale for non-controlled trials. Five studies were included (1 nutrition-only and 4 multimodal prehabilitation studies). Due to substantial heterogeneity in the interventions across studies, a meta-analysis was not conducted. Findings suggest that multimodal prehabilitation, compared with standard hospital care, is associated with improvements in both functional walking capacity and pulmonary function during the preoperative period; however it does not appear to have an effect on postoperative outcomes. Rather, the finding of significantly lower rates of postoperative complications in the intervention group was unique to the nutrition-only study. Multimodal prehabilitation programs that combine nutrition and exercise may have beneficial effects on various physical function outcomes in patients with lung cancer awaiting surgery. Optimizing preoperative nutrition may have postoperative benefits which remain to be confirmed.

Purpose Multimodal prehabilitation programs (exercise, nutrition, and anxiety reduction) have been shown to be successful for enhancing patients' physical function prior to surgery, although adherence remains a challenge. Given the short pre-operative period, maintaining adherence is critical to maximize program effectiveness. This study was designed to better understand patients' perspectives of prehabilitation and to identify factors related to program adherence.Methods A qualitative descriptive study was conducted based on 52 cancer patients enrolled in a prehabilitation program at the Montreal General Hospital, Montreal, Canada. Data was collected with a structured questionnaire designed to evaluate the program.Results Patients enjoyed their experience in prehabilitation, especially the exercise program and training sessions. The primary motivating factor for participation was to be physically prepared for the surgery. The most challenging exercise component was resistance training, while the most enjoyed was the aerobic training. Approximately 50% of patients were interested in group fitness classes as opposed to supervised individual training sessions for reasons related to social support. The preferred methods for exercise program delivery were home-based and one supervised exercise session per week. The biggest barrier to participation was related to transportation.Conclusions These findings highlight the need to make prehabilitation programs more patient-centered. This is critical when designing more effective therapeutic strategies tailored to meet patients' specific needs while overcoming program non-adherence.

High complication rates following colorectal surgery render many patients unable to fully regain functional capacity, thus seriously compromising quality of life. The aim of this study was to assess whether a 4-week trimodal prehabilitation program (exercise, nutritional supplementation, and counseling on relaxation techniques), implemented during the preoperative period, is sufficient to modify exercise behaviors and improve functional capacity of elderly patients scheduled for colorectal cancer surgery. Patients were assigned to either a prehabilitation (PREHAB; n = 57) or matched time control group (CTRL; n = 59). Over the 4-week period prior to surgery, patients in PREHAB participated in a trimodal prehabilitation program. Patients in CTRL received the same program but only postoperatively. The Community Healthy Activities Model Program for Seniors (CHAMPS) questionnaire was used to measure physical activity levels, while the 6-min walk test (6MWT) was used for assessment of functional walking capacity. Measurements were collected at baseline and at the time of surgery. Over the preoperative period, patients in PREHAB significantly increased the amount of moderate- and vigorous-intensity physical activities that they performed. PREHAB patients also demonstrated a greater improvement in 6MWT compared to CTRL. At the time of surgery, a greater proportion of patients in PREHAB met current physical activity guidelines, as compared to CTRL. These findings highlight the positive effects of a trimodal prehabilitation program on patients’ physical activity levels and functional walking capacity and demonstrate that modifying exercise behaviors and improving physical function within the 4-week preoperative period are an achievable goal.
