Androgen deprivation therapy (ADT) plays a central role in the management of men with locally advanced, recurrent, and metastatic prostate cancer. Because most men diagnosed with prostate cancer will die of something other than their cancer, treatment-related adverse effects are highly relevant to their long-term health. Benefits of ADT in each clinical setting must be weighed against ADT-related adverse effects. ADT is detrimental to several metabolic end points and to bone health. ADT has been prospectively shown to cause decreased lean muscle mass, increased fat mass, weight gain, increased cholesterol and triglycerides, insulin resistance, and loss of bone mineral density. In population-based analyses it has been associated with an increased incidence of diabetes, clinical fractures, and cardiovascular disease. Data-driven recommendations for managing these adverse effects are needed. Currently the authors advocate the use of adapted practice guidelines developed to prevent diabetes, fractures, and coronary heart disease in the general population.

Introduction. Androgen deprivation, used to treat prostate cancer, leads to metabolic disorders, including glucose metabolism disorders. The timing of development and the characteristics of these changes have not been sufficiently studied. The expansion of the possibilities for assessing glycemia makes it possible to obtain changes in glucose.Objective. To study the dynamics of the effect of long-term androgen-deprivation therapy with gonadotropin-releasing hormone agonists (GnRH agonists) on the parameters of glucose metabolism and ambulatory glucose profile in patients with locally advanced prostate cancer (La PCa).Materials and methods. The study included 99 patients with La PCa receiving androgendeprivation therapy (ADT) with (GnRH agonists) for at least 12 months. The study of fasting plasma glucose (FPG) and glycated hemoglobin (HbA1c) levels was performed at baseline, after 3, 6 and 12 months of ADT, and constant self-monitoring of glycemia was recommended using portable glucometers. Flash glucose monitoring systems (FreeStyle Libre) were installed in ten patients with a detected increase in glycemia on the background of ADT, allowing them to obtain data on the ambulatory glucose profile (AGP).Results and discussion. Long-term ADT in patients with La PCa, regardless of baseline age, BMI, WC, was accompanied by an early, progressive deterioration in parameters of glucose metabolism. The proportion of patients with prediabetic FPG values after 12 months becames 66% according ADA criteria. We found that 12-month ADT changes the AGP: an increase area under the curve and postprandial glycemic levels, an increase in blood glucose variability with an increase in the CONGA index to 6.817 (p < 0.001).Conclusion. ADT by GnRH agonists in patients with La PCa is accompanied by a predisposition to early disorders of glucose metabolism with a high risk of rapid development of prediabetes regardless of baseline age, BMI, and WC. The AGP of patients is characterized by an increase in the total glycemic load, and glycemic variability.

38 Background: Androgen deprivation therapy (ADT) is a cornerstone of advanced prostate cancer (PCa) treatment, however several side-effects are associated with its long-term use. Notably, loss of bone mineral density (BMD) is accelerated which increases fracture risk. Guidelines recommend BMD testing when initiating ADT to properly assess baseline fracture risk. The objective was to examine the proportion of BMD testing in men initiating long-term ADT in Quebec. Methods: The cohort consists of men extracted from Quebec public healthcare insurance administrative databases who were diagnosed with PCa from 2001-2012 and treated by ADT for at least one continuous year. The primary study outcome was the receipt of baseline BMD testing (defined as a BMD test identified in the period from 6 months prior to and up to 12 months after ADT initiation). Multivariable generalized linear mixed with a logit link was performed to identify variables associated with baseline BMD testing accounting for physician clustering. Results: We identified 7,069 patients, of which 887 (12.6%) underwent baseline BMD testing. Baseline BMD testing varied by year of ADT initiation, from 7.7% in 2001-2003 to 12.3% in 2013-2012. Following multivariable analyses, later years of ADT initiation (2004-2006, 2007-2009, 2010-2012, 2013-2015) remained associated with higher odds of baseline BMD testing compared to the earlier years (2001-2003) (ORs ranging from 1.43-1.88; p < 0.001). Conversely, age > 80 (OR 0.73; 95% CI 0.57-0.94; p = 0.001), greater Charlson comorbidity score (OR 0.51; 95%CI 0.34-0.75; p = 0.001), and rural residence (OR 0.60; 95%CI 0.48-0.75; p < 0.001) were associated with lower odds of baseline BMD testing. Conclusions: In our study population, rates of baseline BMD testing in men initiating ADT are low, although the rates increased over the course of the study period. Potential gaps identified in baseline BMD testing include older, more comorbid patients, and rural residence. Additional efforts emphasizing the importance of BMD testing in PCa guidelines may be needed.

Background:Androgen deprivation therapy (ADT), by inducing severe hypogonadism, leads to a loss of bone mineral density (BMD) and an increased risk of fragility fractures after 6 months of treatment in men with prostate cancer1. However, its effect on bone quality has not been described.Objectives:To evaluate the changes on bone microarchitecture (bone quality) assessed by TBS (trabecular Bone Score) in male patients with prostate cancer after one year of treatment with ADT.Methods:All patients diagnosed with prostate cancer candidates for long-term ADT admitted to Urology department of Hospital Universitari Parc Tauli (reference population of 450,000 inhabitants) between April 2017 and December 2019 were included. Patients who received chemotherapy, previous hormonal therapy or specific treatment for osteoporosis in the last year or those who had a very impaired functional capacity (Barthel index <30) were excluded.Demographic, clinical and analytical data (testosterone, calcium, phosphorous, alkaline phosphatase, 25-hidroxyvitamin D, PTH) were collected in all patients. A bone densitometry (GE-Lunar Prodigy) including the measurement of lumbar spine TBS (L1-L4) using Medimaps Software was performed at baseline and at 12 months of treatment with ADT.Results:78 patients were included. Mean age 77,9±8,3 years. The median Gleason score was 7,88±1,05. 3 patients had previous fragility fracture (one sacral fracture, one fibula and one multiple vertebral fracture). Baseline analytical values in patients were the following: testosterone11,6±74,9 nmol/L.; 25-hidroxyvitamin D 20,8±10,4 ng/ml; PTH 51,8±23,0 pg/ml; CTX 0,58±0,66. The daily calcium intake was 573±207 mg/day.According to BMD, 17 patients (21,8%) had osteoporosis before starting ADT, with the following average T-score values: lumbar spine +0,15±1,85, femoral neck -1,75±1,00, and total hip -1,19±1,16. Mean baseline TBS value of the entire cohort was 1,279±0,122. 30,5% of the patients showed very degraded microarchitecture (TBS<1,230), 28,8% had partially degraded microarchitecture (TBS 1,230-1,310) and in 40,7% showed normal microarchitecture (TBS >1,310).After one year of ADT treatment, TBS mildly worsened in this cohort, with a median value of 1,256±0,131 (p = NS). However up to 43% of patients reached highly degraded microarchitecture, 27% partially degraded and only 29,5% had a normal TBS (p = NS).Conclusion:Most patients with prostate cancer have an altered bone quality before starting ADT. After 12 months of treatment, the percentage of patients with highly degraded bone microarchitecture increases, although not significantly. More studies are needed to confirm this trend and to evaluate if these patients present more long-term fractures.References:[1]Lee R, et al.
