Objectives

Narrative objectives1

Hormone therapy (ADT) for prostate cancer rapidly reduces testosterone to castration levels, which may result in the incidence of lifestyle-related diseases such as obesity, dyslipidemia, and increased insulin resistance. Furthermore, ADT can lead to a significant reduction in muscle strength and bone mineral density, and then worsening the quality of life (QOL) among prostate cancer patients by increased risk of sarcopenia, falls, and fractures. Therefore, when ADT is administered for prostate cancer patients, it is important to prevent these serious conditions by improving diet and lifestyle habits, and appropriate exercise therapy.
The present study assesses an efficacy of a non-invasive and feasible exercise program in daily life on prevention of muscle weakness caused by ADT among
locally advanced prostate patients undergoing radical radiation therapy combined with hormone therapy (approximately 2 years of combined hormone therapy and radiation therapy) and the metastatic prostate cancer patients with ADT. This is a prospective observational study.

Assessment

Primary outcomes

Changes in systemic muscle mass, Lower limb muscle mass, and grip power (items associated with sarcopenia) 3, 6, 9. 12, 18, 24, 30, and 36 months after initiation of ADT.

Key secondary outcomes

The following items before and after the start of treatment:
1. Height, weight, BMI, body fat percentage, and waist circumference
2. Locomotor syndrome test
3. Short Physical Performance Battery
4. Clinical Frailty Scale
5. Bone mineral content (evaluated at the femoral neck)
6. Skeletal muscle index at L3 level on CT (L3-SMI)

Interventions/Control_1

All participants are asked to perform physical exercise in their daily lives.
Physical excercise is performed as a home program. A home program includes excercises recommended by the Ministry of Health, Labor and Welfare and the Japan Orthopedic Association, as following;1.Walking of 8000 steps a day, three times per week, 2.Diary locomotor-training. All subjects were asked to keep a diary about how well they were able to perform these exercises.
Based on a diary and data of smart band, all participants are divided into three groups as following; patients who performed a lot of exercise therapy (80% or more), ones who performed it to a certain extent (40-80%), and the group who performed it very little (less than 40%). All data are compared in these three groups. Short-term efficacy (6 months) and long-term efficacy (36 months) of physical exercise are assessed.
