Baumann2, Cécile Weiß1, Hartmut Bertz1, Gabriel Seifert3, Hannes Neeff3,4 and Christine Greil1  \nAbstract  \nBackground Perioperative morbidity in gastrointestinal (GI) cancers is closely associated with reduced physical fitness and impaired nutritional status. While prehabilitation has been shown to improve outcomes in patients with colorectal cancer (CRC), it is not yet standard of care and remains underexplored in other GI malignancies. This study evaluates the feasibility, safety, and preliminary effectiveness of a supervised moderate-to-high intensity exercise program combined with nutritional counseling in a cohort of GI cancer patients scheduled for surgery.  \nMethods In a prospective, two-arm, controlled trial, patients scheduled for GI cancer surgery were assigned to aprehabilitation program (2–3 sessions/week ≥ 3 weeks, endurance and resistance training with nutritional counseling) or usual care. Primary endpoints were feasibility (eligibility, recruitment, acceptance, retention, adherence) and safety (adverse events) . Secondary endpoint was quality of life (QoL; EORTC QLQ-C30 global score, SF-36 physical and mental health component scores, PCS, MCS), assessed at baseline (t0), presurgery (t1), hospital discharge (t2), and 12-week follow-up (t3) .  \nResults Among the 400 patients assessed for eligibility, 36% met the eligibility criteria. Of those approached, 41% consented to participate, resulting in an overall recruitment rate of 27%(n = 38) . Of the recruited patients, 84% completed the study (n = 32; prehabilitation = 17; usual care = 15; mean age 63.5 years, range 38—85; ICD-10 C15-C26) . Participants attended 95% of the planned sessions (8 .1 ± 3 . 6) within a mean of 30 days (SD ± 16) and completed 59% at the target intensity. Nutritional counseling was provided to 94% of the patients. No intervention-related serious adverse events occurred. A modest improvement in PCS was observed in the prehabilitation group at t1 (+ 4.25 points), although this finding reached statistical significance only in the one-tailed analysis. No between-group differences were observed for global QoL or MCS.  \nConclusion Multimodal prehabilitation combining supervised moderate-to-high intensity exercise with nutritional counseling is feasible and safe in a real-world GI cancer population.
