Abstract: | Purpose: The American Cancer Society (ACS) Guidelines on Nutrition and Physical Activity for Cancer Survivors recommend avoiding obesity, engaging in regular physical activity, following a healthy diet, and limiting alcohol intake. This study aimed to assess the association between adherence to these guidelines and all-cause mortality, cardiovascular disease mortality (CVDM), and prostate cancer-specific mortality (PCSM) among prostate cancer patients and to explore whether the association varies by tumor aggressiveness. Methods: Data from 4,232 prostate cancer patients in the Cancer Prevention Study-II Nutrition Cohort were analyzed. Adherence to ACS guidelines was scored (0-8), with higher scores indicating greater adherence. Multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for mortality were calculated using Cox proportional hazards regression models. Results: Higher ACS guideline score was associated with lower risk of all-cause mortality (HR for score 6-8 vs. 0-3: 0.77; 95% CI, 0.69 to 0.85), CVDM (HR: 0.75; 95% CI, 0.63 to 0.91), and PCSM (HR: 0.79; 95% CI, 0.60 to 1.03). Among patients with non-aggressive tumors, higher adherence was associated with significantly lower all-cause mortality (HR: 0.78; 95% CI, 0.70 to 0.87) and CVDM (HR: 0.79; 95% CI, 0.65 to 0.98) but not PCSM. A higher score was associated with lower all-cause mortality (HR: 0.75; 95% CI, 0.58 to 0.95) but not CVDM or PCSM among men with aggressive tumors. Conclusion: Adherence to ACS guidelines was associated with lower all-cause mortality and CVDM in prostate cancer patients, particularly those with non-aggressive tumors. These findings emphasize the potential benefit of post-diagnosis lifestyle modifications. |
