Opis
Sarcopenia, decrease lean body mass (LBM) is the well-known parameter which negatively related to physical activity, morbidity and patients survival. Aging and decreased blood androgen level are well known risk factors of sarcopenia in male population.
Androgen deprivation therapy (ADT) is commonly performed in advanced or recurred prostate cancer patient and lead to accelerating decreasing blood androgen level. The previous studies defined the sarcopenia after ADT by calculated the (muscle component area) / (total body area) on computed tomography (CT) scan. However, CT scan is not recommended for routine follow up examination of ADT patients thus this measurement of sarcopenia has limitation on clinical usage.
This study using Inbody 320 for measure body composition. Inbody 320 based on multi-frequency Bioelectrical Impedance Analysis(BIA) method that calculated specific body component by differences in impedance indexes of fat, muscle and extracellular body fluid. Inbody measurement show precision accuracy and safety on body composition measurement, thus it frequently used in studies of obesity, nutrition and sports fields.
We calculating the total skeletal muscle mass (SMM), skeletal muscle index(SMI), relative skeletal muscle mass index (RASM), fat body mass (FBM), body mass index (BMI), body fat percentage, body water content, and edema value by Inbody 320 in the patients who treated by ADT in prostate cancer patients. Enrolled patients check the body composition parameters at the baseline (before ADT) and after ADT 3,6,12,18,24 months.
We prospectively measuring the 2 years changes of body composition and sarcopenia after ADT treatment. Patients characteristics (Age, underlying disease), Prostate cancer status (PSA level, Gleason grade group, initial treatment), ADT methods characters (timing, type) and oncological outcome (Recurrence, Metastasis, Castration resistance) were measuring in the cohort population.
Post hoc analysis were performed in the timing (initial, salvage or adjuvant) or type (LHRH agonist, Antiandrogen or surgical castration) of ADT for development of sarcopenia. Sub-arm analysis were performed for assessing that effect of presence of sarcopenia on oncological outcome and functional outcomes after ADT.

| Cohort: ADT patients All enrolled patient data entered in single group cohort. All patient who started androgen deprivation therapy for prostate cancer can included this cohort by following inclusion and exclusion criteria. We do not planned any intervention on this cohort. We measuring changes of body composition by Inbody 320 in the planned follow-up period.
We planned sub-group analysis for timing of intervention (Intervention 1) , ADT type(Intervention 2), LHRH agonist type(Intervention 3), patients age(Intervention 4), initial PSA level (Intervention 5) and Gleason Grade Group (Intervention 6). | Diagnostic Test: Cohort: ADT patients Total Skeletal muscle mass (SMM), Skeletal muscle index (SMI), Relative Skeletal muscle mass index (RASM), Fat body mass (FBM), Body mass index (BMI), Body fat percentage, Body water content, Edema Value were calculated by Inbody 320 |
