Introduction: Although the benefits of post-operative rehabilitation in cancer surgery are well established, the role of prehabilitation is less defined. Oesophagogastric cancers present a unique opportunity to study the impact of prehabilitation during the neoadjuvant window, whether with chemotherapy or chemoradiotherapy (NCT) in patients who are frequently nutritionally depleted. This trial examines the impact of a community-based exercise program on patient fitness during and after the neoadjuvant window.
Methods: A pragmatic, randomized controlled multi-centre trial was undertaken in three centres. Inclusion criteria were patients aged ≥ 18 years planned for NCT and esophagectomy or gastrectomy. Participants were randomized 1:1 to an exercise prehabilitation group (EX) or to usual care (UC). The primary endpoint was cardiorespiratory fitness between baseline and pre-surgery timepoint using the 6-min walk test. Secondary endpoints included hand dynamometer, 10-sec sit to stand, activity behaviour, body mass index, semi-structured interviews, questionnaires assessing quality of life, surgical fear, general self-efficacy and mastery.
Results: Between March 2019 and December 2020, 71 participants were recruited: EX (n=36) or UC (n=35). From baseline to pre-surgery, the difference-in-difference for EX showed a significant improvement in 6MWT of 50.7m (P=0.05) compared to UC [mean (SD): 522.1m (+/-104.3) to 582.1m (+/-108) vs. 497.5m (+/-106.3) to 506.0 m (+/-140.4). There was no statistically significant DID for secondary outcome measures.
Conclusions: This community exercise prehabilitation program significantly improves physical fitness for surgery, is feasible and provides a standardized framework for prescription of exercise in esophagogastric cancer patients undergoing NCT.
