A three-year programme after curative treatment is expected to improve disease-free survival through insulin and IGF reduction, lower inflammation and immune surveillance. Level-1 evidence now exists, so implementation is the barrier: reimbursement, workforce and adherence. The test is CHALLENGE-design trials in TNBC and prostate cancer with health-economic analysis and digital delivery arms. Being tested at scale, it addresses the bottlenecks Cachexia, toxicity and the limits of the patient and Survivorship and late effects are neglected.","asOf":"2026-09-04","links":[{"label":"CHALLENGE: structured exercise after adjuvant chemotherapy for colon cancer (NEJM 2025)","url":"https://doi.org/10.1056/NEJMoa2502760"}],"tags":[],"related":[],"cancers":["colorectal","tnbc","prostate"],"sections":[],"technologies":["exercise-oncology"],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"hypothesis":"A 3-year structured exercise programme after curative treatment improves iDFS in TNBC (and other cancers) with effect sizes comparable to some adjuvant drugs.","rationale":"Mechanisms include insulin/IGF reduction, inflammation, and immune surveillance; effect size in CHALLENGE (DFS HR 0.72) rivals drugs.","test":"Run CHALLENGE-design trials in TNBC and prostate cancer with health-economic analysis and digital delivery arms.","maturity":"being-tested-at-scale"},"route":"/ideas/idea-exercise-as-adjuvant/","neighbours":{"cancer":[{"id":"colorectal","kind":"cancer","name":"Colorectal cancer","route":"/cancers/colorectal/"},{"id":"prostate","kind":"cancer","name":"Prostate cancer","route":"/cancers/prostate/"},{"id":"tnbc","kind":"cancer","name":"Triple-negative breast cancer (TNBC)","route":"/cancers/tnbc/"}],"technology":[{"id":"exercise-oncology","kind":"technology","name":"Exercise & lifestyle oncology","route":"/technologies/exercise-oncology/"},{"id":"structured-exercise-survivorship","kind":"technology","name":"Structured exercise programmes after curative treatment","route":"/technologies/structured-exercise-survivorship/"},{"id":"exercise-prescription-after-cancer","kind":"technology","name":"The exercise prescription after cancer: the dose the guidelines state","route":"/technologies/exercise-prescription-after-cancer/"}],"idea":[{"id":"idea-fund-cachexia-programme","kind":"idea","name":"A dedicated programme for cachexia and treatment toxicity research","route":"/ideas/idea-fund-cachexia-programme/"},{"id":"idea-nl-exercise-dose-finding","kind":"idea","name":"A dose-finding trial for exercise after cancer","route":"/ideas/idea-nl-exercise-dose-finding/"},{"id":"idea-fund-survivorship-endowment-levy","kind":"idea","name":"A survivorship research endowment funded by a levy on curative therapy prices","route":"/ideas/idea-fund-survivorship-endowment-levy/"},{"id":"idea-bio2-gdf15-plus-exercise","kind":"idea","name":"Combine the new anti-wasting antibody with exercise and protein","route":"/ideas/idea-bio2-gdf15-plus-exercise/"},{"id":"idea-bio2-prehabilitation-standard","kind":"idea","name":"Four weeks of training and nutrition before major cancer surgery, as standard","route":"/ideas/idea-bio2-prehabilitation-standard/"},{"id":"idea-acc-prehabilitation-older-surgery","kind":"idea","name":"Multimodal prehabilitation for older patients before major cancer surgery","route":"/ideas/idea-acc-prehabilitation-older-surgery/"},{"id":"idea-bio2-exercise-reimbursement","kind":"idea","name":"Pay for supervised exercise the way we pay for drugs","route":"/ideas/idea-bio2-exercise-reimbursement/"},{"id":"idea-prostate-other-cause-mortality-as-a-reported-service-outcome","kind":"idea","name":"Report death from other causes as an outcome of the prostate cancer service, split by deprivation and ethnicity","route":"/ideas/idea-prostate-other-cause-mortality-as-a-reported-service-outcome/"},{"id":"idea-bio2-protein-plus-training-during-io","kind":"idea","name":"Test protein and resistance training during immunotherapy","route":"/ideas/idea-bio2-protein-plus-training-during-io/"},{"id":"idea-acc-cognitive-rehabilitation-after-chemotherapy","kind":"idea","name":"Trials of structured cognitive rehabilitation for cancer-related cognitive impairment","route":"/ideas/idea-acc-cognitive-rehabilitation-after-chemotherapy/"}],"bottleneck":[{"id":"b-cachexia-supportive","kind":"bottleneck","name":"Cachexia, toxicity and the limits of the patient","route":"/bottlenecks/b-cachexia-supportive/"},{"id":"b-survivorship","kind":"bottleneck","name":"Survivorship and late effects are neglected","route":"/bottlenecks/b-survivorship/"}],"paper":[{"id":"paper-challenge-exercise-nejm-2025","kind":"paper","name":"CHALLENGE: a structured exercise programme after chemotherapy improves survival in colon cancer","route":"/key-papers/paper-challenge-exercise-nejm-2025/"}],"trial":[{"id":"challenge","kind":"trial","name":"CHALLENGE (CCTG CO.21)","route":"/trials/challenge/"}],"roadmap":[{"id":"nutrition-lifestyle-roadmap","kind":"roadmap","name":"Diet, exercise and lifestyle roadmap: causes established → interventions that disappointed → exercise proven as treatment","route":"/roadmaps/nutrition-lifestyle-roadmap/"}]}}
