Clinical Trial Summary

The proposed pilot study aims at determining the feasibility of a lifestyle intervention including adherence to a personalised dietary regimen combined with regular physical activity in patients newly diagnosed with prostate cancer under androgen deprivation therapy.

Description:

Prostate cancer (PCa) is among the most frequent tumor types and is the second deadliest type of cancer in men.

PCa has a multifactorial aetiology; modifiable environmental factors, including diet and obesity, have been associated with prostate carcinogenesis. Furthermore, patients with PCa are treated with androgen deprivation therapy (ADT), which has negative effects on the cardiovascular system and body composition, particularly on the fat and muscle mass, bone health and psychological wellbeing.

Data in the current literature suggests that a lifestyle intervention e.g. with targeted and supervised exercise therapy or a dietary intervention with a prudent dietary patternmay positively influence the quality of life and the course of the disease of patients under ADT. However, conclusive data is missing.

The proposed pilot study aims at determining the feasibility and the effect of a lifestyle intervention including adherence to a personalised dietary regimen combined with regular physical activity in patients newly diagnosed with PCa under ADT.
