Mediterranean-style dietary pattern improves cancer-related fatigue and quality of life in men with prostate cancer treated with androgen deprivation therapy: A pilot randomised control trial

Cancer-related fatigue (CRF) is a prevalent and persistent symptom from androgen deprivation therapy (ADT) in prostate cancer. The Mediterranean-style dietary pattern (MED-diet) offers a plausible mechanism to mitigate CRF through reducing inflammation and improving body composition. This study aimed to evaluate the effects of a 12-week MED-diet, compared to usual care, on CRF and quality of life in men with prostate cancer treated with ADT..

..The MED-diet improved CRF (FACIT-F) at 8-weeks [+4.8 (0.0, 9.8); P = 0.05] and 12-weeks [+7.2 (2.2, 12.0); P = 0.005], quality of life (FACIT-G) at 12-weeks [+9.2 (2.7, 15.8); P = 0.006], reduced total body mass at 8-weeks [−2.51 kg (−4.25, −0.78); P = 0.005] and 12-weeks [-2.97 kg (−4.71, −1.25); P = 0.001], lean mass at 8-weeks [−1.50 kg (−2.91, −0.10); P = 0.036], and IL-8 at 8-weeks [-0.18 ng/ml (−0.34, −0.02); P = 0.029] compared to usual care. The MED-diet demonstrated zero adverse events, 91% study completion, 100% attendance, and 81% adherence to the MEDAS.

Conclusion
The MED-diet is safe and feasible, and has the potential to improve CRF and quality of life in overweight men treated with ADT compared to usual care. Further exploration of the MED-diet is warranted in a larger powered sample size to consolidate these findings.
