Inclusion criteria

1. Be age 65 or over. 2. Be diagnosed with stage I-III Cancer. 3. Have completed curative intent treatment ≤10 years prior to screening. (Patients on endocrine therapies are allowed to enroll.) 4. Have a Fried's Frailty Score (FFS) of ≥ 2. 5. Able to provide informed consent, or have consent given by patient-designated health care proxy per institutional policies and University of Rochester Cancer Control guidelines.

Exclusion criteria

Study subjects must not: 1. Have chemotherapy planned for the during of the study. 2. Have abnormal liver function tests (ALT, AST and bilirubin ≥3 times institutional upper limit of normal) per most recent available lab test (within 3 months of screening). 3. Have uncontrolled or unmanaged liver disease. 4. Consume more than 6 cups of green tea per day. 5. Have known allergies to caffeine. 6. Be diagnosed with a major psychiatric illness requiring hospitalization within the last year. 7. Be diagnosed with dementia. 8. Cannot provide informed consent due to lack of decision making capacity (as determined by the patient's oncologist) and has no patient-designated health care proxy per institutional policies and University of Rochester Cancer Control URCC guidelines.

Participant flow

Recruitment details

Patients were recruited from clinical sites within Wilmot Cancer Institute between April 2021 and March 2023. Eligible patients were aged 65 or older, diagnosed with Stage I-III solid cancer, completed curative intent treatment 10 years or less before being screened, and had a Fried's Frailty Score (FFS ≥ 2); assessed by measuring grip strength, weight loss, physical activity, fatigue, and a 4-meter walk test. The first participant was consented on April 28, 2021, and randomized on May 6, 2021.

Pre-assignment details

Sixty four (64) potentially eligible participants were approached and 24 participants were consented. Of the 24 consented subjects: 5 screen failed (participant was consented but didn't fully meet eligibility criteria e.g. meet frailty cut off or liver toxicity screen); 4 screen withdrew (participant was consented but withdrew from the study before the baseline visit for randomization), and 1 was lost to follow up. Fourteen (14) participants were randomized to the treatment groups.
