Abstract Purpose. American Indian/Alaska Native (AI/AN) people have the worst cancer survival rates of any US racial group, are underrepresented in clinical trials and research, and have never been recruited for participation in any published prehabilitation (prehab) intervention conducted prior to cancer surgery. Description of Procedure. We are collaborating with tribal partners to design the first prehab translational clinical trial for AI patients diagnosed with obesity-related cancer, to be implemented prior to surgical resection of the tumor. Program components have been developed with community input through semi-structured interviews and guidance from the sponsoring tribal health facility, the San Carlos Apache Healthcare Corporation. Patients preparing for cancer surgery will engage in a 3-week multimodal intervention that entails home-based exercise, supervised fitness sessions, promotion of anti-inflammatory foods, and health education materials adapted for and by community members. Serum and tissue biomarkers, as well as lifestyle behavioral measures, will be compared pre and post intervention to assess responsiveness. In respect of tribal sovereignty, the experimental procedure includes protocol refinement and approval by the tribal health facility’s IRB and tribal council. Summary of Data. Our qualitative data reveal AI cancer survivors from the partnering tribal community have high interest in prehab and attest they would have participated if offered (100%). Their consensus feedback fashioned the specifics of the prehab translational clinical trial: 30 minutes daily walking, 60 minutes supervised resistance training twice weekly, 2 ounces walnut consumption daily, nutrition counseling, transportation assistance, and education/encouragement from staff and peers. Biospecimen sampling can be a sensitive topic for AI audiences, which we addressed early and found 75% of the interviewed survivors agreed to biospecimen collection without stipulation; this increased to 100% support once the rationale for biospecimens was explained. Conclusions: Published prehab studies in other populations administered for 3-5 weeks between diagnosis and surgery have shown improvements in functional capacity, attenuation of surgery-induced losses, alterations of inflammatory biomarkers, and patient safety. Our community-informed prehab translational clinical trial for AI patients is the first of its kind, and anticipated to demonstrate feasibility, patient acceptability, behavioral changes in lifestyle, and the potential to modulate inflammatory biomarkers.
