Front Oncol 2024; 14:1345322. [PMID: 38357197 PMCID: PMC10864500 DOI: 10.3389/fonc.2024.1345322] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Accepted: 01/15/2024] [Indexed: 02/16/2024] Open
Abstract
Background Androgen deprivation therapy (ADT) is the foundational treatment for metastatic prostate cancer (PCa). Androgen receptor (AR) axis-targeted therapies are a new standard of care for advanced PCa. Although these agents have significantly improved patient survival, the suppression of testosterone is associated with an increased risk of cardiometabolic syndrome. This highlights the urgency of multidisciplinary efforts to address the cardiometabolic risk of anticancer treatment in men with PCa. Methods Two professional organizations invited five urologists, five clinical oncologists, and two cardiologists to form a consensus panel. They reviewed the relevant literature obtained by searching PubMed for the publication period from April 2013 to April 2023, to address three discussion areas: (i) baseline assessment and screening for risk factors in PCa patients before the initiation of ADT and AR axis-targeted therapies; (ii) follow-up and management of cardiometabolic complications; and (iii) selection of ADT agents among high-risk patients. The panel convened four meetings to discuss and draft consensus statements using a modified Delphi method. Each drafted statement was anonymously voted on by every panelist. Results The panel reached a consensus on 18 statements based on recent evidence and expert insights. Conclusion These consensus statements serve as a practical recommendation for clinicians in Hong Kong, and possibly the Asia-Pacific region, in the management of cardiometabolic toxicities of ADT or AR axis-targeted therapies in men with PCa.

Abstract
PURPOSE To assess whether androgens play a role in explaining the sex related differences in the incidence of colorectal cancer (CRC). METHODS A nationwide matched cohort study was conducted employing the Prostate Cancer data Base Sweden (PCBaSe) 4.0 during the study period 2006-2016. Prostate cancer (PC) patients receiving androgen deprivation therapy (ADT) were treated as exposed. Prostate cancer-free men from the general population were randomly selected and matched to the index case by birth year and county of residence, forming the unexposed group. All were followed until a diagnosis of CRC, death, emigration, or end of the study period. The risk of CRC among ADT exposed PC patients compared to unexposed cancer-free men was calculated using a flexible parametric survival model and expressed as hazard ratios (HRs) with 95% confidence intervals (CIs). RESULTS There was an increased risk of CRC among ADT exposed PC patients compared to unexposed cancer-free men (HR 1.27 [95% CI 1.15-1.41]), in particular an increased risk of adenocarcinoma of the colon (HR 1.33 [95% CI 1.17-1.51]) and more specifically an increased risk of adenocarcinoma of the distal colon (HR 1.53 [95% CI 1.26-1.85]). Examination of latency effects yielded significantly decreased HRs over time for CRC (p = 0.049 for trend). CONCLUSIONS This population-based study found an increased risk of CRC among PC patients exposed to ADT, specifically adenocarcinoma of the distal colon, which indicates an increased association between ADT (PC + ADT) and CRC but not a positive dose-response trend questioning a true causal effect.

Adverse metabolic consequences of androgen deprivation therapy (ADT) on Asian patients with prostate cancer: Primary results from the real-life experience of ADT in Asia (READT) study. Prostate 2023; 83:801-808. [PMID: 36938957 DOI: 10.1002/pros.24519] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2022] [Revised: 02/10/2023] [Accepted: 03/02/2023] [Indexed: 03/21/2023]
Abstract
BACKGROUND Androgen deprivation therapy (ADT) use in prostate cancer (PCa) has seen a rising trend. We investigated the relationship between ADT and adverse changes in metabolic parameters in an Asian population. METHODS This is an international prospective multicenter single-arm cohort yielded from the real-life experience of ADT in Asia (READT) registry. Consecutive ADT-naïve patients diagnosed of PCa and started on ADT were prospectively recruited from 2016 and analyzed. Baseline patient characteristics, PCa disease status, and metabolic parameters were documented. Patients were followed up at 6-month interval for up to 5 years. Metabolic parameters including body weight, lipid profiles, and glycemic profiles were recorded and analyzed. RESULTS 589 patients were eligible for analysis. ADT was associated with adverse glycemic profiles, being notable at 6 months upon ADT initiation and persisted beyond 1 year. Comparing to baseline, fasting glucose level and hemoglobin A1c level increased by 4.8% (p < 0.001) and 2.7% (p < 0.001), respectively. Triglycerides level was also elevated by 16.1% at 6th month and by 20.6% at 12th month compared to baseline (p < 0.001). Mean body weight was 1.09 kg above baseline at 18th month (p < 0.001). CONCLUSION ADT was associated with adverse metabolic parameters in terms of glycemic profiles, lipid profiles, and body weight in the Asian population. These changes developed early in the treatment and can persist beyond the first year. Regular monitoring of the biochemical profiles during treatment is paramount in safeguarding the patients' metabolic health.

Abstract
BACKGROUND Androgen deprivation therapy (ADT), a backbone treatment for advanced prostate cancer (PC), is known to have a variety of metabolic side effects. We conducted an updated meta-analysis to quantify the metabolic risks of ADT. MATERIALS AND METHODS We searched PubMed, Web of Science, and Scopus in May of 2022 for studies investigating the risk of metabolic syndrome (MetS), diabetes, and hypertension from ADT in PC patients using keywords. Only full-length studies with a control group of PC patients not on ADT were included. All results compatible with each outcome domain in each included study were sought. For included studies, relative risk (RR) was pooled using a random effects model and a trim-fill approach was used to adjust for publication bias. RESULTS 1,846 records were screened, of which 19 were found suitable for data extraction. Five studies, including 891 patients, were evaluated for MetS as an outcome, with the random effects model showing a pooled RR of 1.60 ([95% Confidence Interval (CI), 1.06-2.42]; P=0.03) for patients on ADT while twelve studies, including 336,330 patients, examined diabetes as an outcome, and the random effects model showed a RR of 1.43 ([95% CI, 1.28-1.59]; P< 0.01). After adjustment for publication bias, ADT was associated with a 25% increased risk for diabetes but was not associated with MetS. 4 studies, including 7,051 patients, examined hypertension as an outcome, and the random effects model showed a RR of 1.30 ([95% CI, 1.08-1.55]; P=0.18) in ADT patients. CONCLUSION In patients with PC, ADT was not associated with MetS and the association with diabetes was not as strong as previously reported. Our novel meta-analysis of hypertension showed that ADT increased the risk of hypertension by 30%. These results should be understood in the context of collaborating care between a patient's oncologist and primary care provider to optimize care.

Abstract
PURPOSE Androgen deprivation therapy (ADT) use in prostate cancer (PCa) has seen a rising trend. We are looking into the relationship between ADT and development of metabolic diseases in Chinese patients. METHODS This is a prospective multi-centre cohort yielded from the READT database (Real-life experience of ADT in Asia), in which patients diagnosed of PCa and offered ADT were prospectively recruited since 2016. Chinese patients recruited from Hong Kong were selected and compared to another cohort of newly diagnosed PCa patients in Hong Kong (HK-Cap database), which was collected prospectively and retrieved retrospectively for this study. Patient outcomes are followed through for 2 years. We compared between the groups the new diagnoses of hypertension, diabetes and hyper-lipidaemia, as well as the initiation of related medication for these conditions. Baseline characteristics including pre-treatment comorbidities, medications and tumour characteristics are documented. RESULTS 151 patients receiving ADT (from READT database) and 447 patients not receiving ADT (from HK-Cap database) were analysed. ADT is related to higher risks of developing any of concerned medical co-morbidities (23.8% vs 13.0*, p = 0.001) and new-onset DM (16.6% vs 4.4%, p < 0.001). Initiation of new medications is also more common in ADT patients. New anti-hypertensives (37.8% vs 12.5%, p < 0.001), oral hypoglycemic agents (12.6% vs 4.9%, p = 0.001), insulin (4.0% vs 0.05%, p = 0.001) and statin (23.7% vs 12.8%, p = 0.023) are more commonly added in ADT cohort. CONCLUSION Chinese receiving ADT are exposed to increased risks of new-onset hypertension, diabetes and hyper-lipidaemia, and a higher likelihood of stepping up pharmaceutical control for pre-existing comorbidities. This highlights physicians' role to monitor metabolic profiles in at-risk men upon offering ADT.

Abstract
INTRODUCTION Androgen deprivation therapy (ADT) is a key treatment modality in the management of prostate cancer (PCa), especially for patients with metastatic disease. Increasing evidences suggest that patients who received ADT have increased incidence of diabetes, myocardial infarction, stroke, and even mortality. It is important to understand the pathophysiological mechanisms on how ADT increases cardiovascular risk and induces cardiovascular events, which would provide important information for potential implementation of preventive measures. METHODS Twenty-six 12-week-old male SD rats were divided into four groups for different types of ADTs including: the bilateral orchidectomy group (Orx), LHRH agonist group (leuprolide), LHRH antagonist group (degarelix), and control group. After treated with drug or adjuvant injection every 3 weeks for 24 weeks, all rats were sacrificed and total blood were collected. Aorta, renal arteries, and kidney were preserved for functional assay, immunohistochemistry, western blot, and quantitative reverse-transcription polymerase chain reaction. RESULTS In vascular reactivity assays, aorta, intrarenal, and coronary arteries of all three ADT groups showed endothelial dysfunction. AT1R and related molecules at protein and messenger RNA (mRNA) level were tested, and AT1R pathway was shown to be activated and played a role in endothelial dysfunction. Both ACE and AT1R mRNA levels were doubled in the aorta in the leuprolide group while Orx and degarelix groups showed upregulation of AT1R in the kidney tissues. By immunohistochemistry, our result showed higher expression of AT1R in the intrarenal arteries of leuprolide and degarelix groups. The role of reactive oxygen species in endothelial dysfunction was confirmed by DHE fluorescence, nitrotyrosine overexpression, and upregulation of NOX2 in the different ADT treatment groups. CONCLUSION ADT causes endothelial dysfunction in male rats. GnRH receptor agonist compared to GnRH receptor antagonist, showed more impairment of endothelial function in the aorta and intrarenal arteries. Such change might be associated with upregulation and activation of AngII-AT1R-NOX2 induced oxidative stress in the vasculature. These results help to explain the different cardiovascular risks and outcomes related to different modalities of ADT treatment.

Abstract
OBJECTIVES We aimed to investigate whether the risk of diabetes mellitus (DM) is heightened in patients with prostate cancer receiving injection therapy. METHODS Men diagnosed with prostate cancer between 2000 and 2012 were included in the case cohort, and men without prostate cancer were included as controls. Each patient with prostate cancer was matched with a control patient with the same index year, demographic variables and comorbidities, and comparisons were made using propensity score matching. The hazard ratio of DM was estimated using the Cox proportional hazards model. RESULTS This cohort study consisted of 1213 patients with prostate cancer and 1213 control patients. The risk of DM in patients with prostate cancer was 1.60 times (95% CI = 1.12, 2.27) that of patients without prostate cancer. Compared with the controls, the hazard ratios of DM for patients with prostate cancer not receiving oral hormone therapy, patients with prostate cancer receiving oral hormone therapy, and patients with prostate cancer not receiving injection hormone therapy were 1.65 (95% CI = 1.01, 2.70), 1.57 (95% CI = 1.07, 2.70), and 1.94 (95% CI = 1.34, 2.81), respectively. The risk of DM in patients who received injection hormone therapy was 0.45 times (95% CI = 0.25, 0.82) that of patients who did not receive injection hormone therapy. CONCLUSION Patients with prostate cancer had an increased risk of DM compared with patients without prostate cancer. Patients with prostate cancer who received injection therapy had a lower risk of DM compared with those who did not.

A cross-sectional study on gut microbiota in prostate cancer patients with prostatectomy or androgen deprivation therapy. Prostate Cancer Prostatic Dis 2021; 24:1063-1072. [PMID: 33850270 DOI: 10.1038/s41391-021-00360-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2020] [Revised: 02/25/2021] [Accepted: 03/23/2021] [Indexed: 12/15/2022]
Abstract
BACKGROUND Androgen deprivation therapy (ADT), either by medical or surgical castration, is the backbone for standard treatment of locally advanced or metastatic prostate cancer, yet it is also associated with various metabolic and cardiovascular complications. Recent evidence have shown that obesity, insulin resistance, or metabolic disturbances can be associated with changes in the gut microbiome, while animal studies also show that castration is associated with changes in the gut microbiome. This study aims to investigate whether the fecal microbiota in prostate cancer patients who had undergone prostatectomy or ADT are different, and explore changes in phylogeny and pathways that may lead to side effects from ADT. METHODS A total of 86 prostate cancer patients (56 patients on ADT and 30 patients with prostatectomy) were recruited. The fecal microbiota was analyzed by the 16S rRNA gene for alpha- and beta-diversities by QIIME2, as well as the predicted metabolic pathways by Phylogenetic Investigation of Communities by Reconstruction of Unobserved States 2. RESULTS The alpha-diversity was significantly lower in the ADT group. The beta-diversity was significantly different between the groups, in which Ruminococcus gnavus and Bacteroides spp were having higher relative abundance in the ADT group, whereas Lachnospira and Roseburia were reduced. The Firmicutes-to-Bacteroidetes ratio is noted to be lower in the ADT group as well. The functional pathway prediction showed that the biosynthesis of lipopolysaccharide (endotoxin) and propanoate was enriched in the ADT as well as the energy cycle pathways. This study is limited by the cross-sectional design and the clinical heterogeneity. CONCLUSIONS There is a significant difference in gut microbiome between prostate cancer patients on ADT and prostatectomy. We theorize that this difference may contribute to the development of metabolic complications from ADT. Further longitudinal studies are awaited.

Abstract
BACKGROUND Despite improved survival rates, cancer survivors are experiencing worse health outcomes with complications of treatment, such as type 2 diabetes mellitus (T2D), that may deteriorate survivorship. The purpose of this review was to provide a comprehensive review of T2D incidence following cancer diagnosis. METHODS The study included: (1) cohort studies, (2) cancer diagnosis by a doctor, (3) incidence of T2D after diagnosis of cancer, and (4) adult patients over 18 years. Studies that focused on patients who had T2D as a preexisting condition at cancer diagnosis were excluded. RESULTS Of a total of 16 studies, overall incidence of T2D ranged from 5.4% to 55.3%. The highest T2D incidence rate was observed in colorectal patients with cancer (53%). While results in prostate patients with cancer were mixed, patients who underwent androgen deprivation therapy (ADT) had a significantly higher incidence of new-onset T2D (12.8%, p = 0.01). Patients treated with chemotherapy within 1-5 years of initial diagnosis of colorectal cancer were at approximately 30% higher risk of T2D. One study found that 48% of T2D was preventable with optimal management during the process of patient care. CONCLUSION Blood glucose management may allow physicians to intervene early and improve outcomes among patients with cancer.

Comparative study of surgical orchidectomy and medical castration in treatment efficacy, adverse effects and cost based on a large prospective metastatic prostate cancer registry. Urol Oncol 2020; 38:682.e1-682.e9. [PMID: 32475745 DOI: 10.1016/j.urolonc.2020.05.005] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2019] [Revised: 04/26/2020] [Accepted: 05/04/2020] [Indexed: 10/24/2022]
Abstract
INTRODUCTION Androgen deprivation therapy (ADT) remains the mainstay of treatment for metastatic prostate cancer (mPCa) but is associated with significant morbidities. Comparisons of medical castration (MC) and surgical orchidectomy (SO) have yielded varied results. We aimed to evaluate the oncological outcomes, adverse effect (AE) profiles and costs of MC and SO in patients with mPCa. METHODS AND MATERIALS We reviewed 523 patients who presented with de novo mPCa from a prospectively maintained prostate cancer database over 15 years (2001-2015). All patients received ADT (either MC or SO) within 3 months of diagnosis. The data were analyzed with chi-square, binary and logistics regression models. RESULTS One hundred and fifty one (28.9%) patients received SO while 372 (71.1%) patients had MC. The median age of presentation was 73 [67 -79] years old. The median prostate-specific antigen (PSA) was 280ng/ml [82.4-958]. Three hundred and thirty one patients (66.3%) had high volume bone metastasis and 57 patients (10.9%) had visceral metastasis. Clinical demographics and clinicopathological were similar across both groups. Similar oncological outcomes were observed in both groups. The proportion of PSA response (PSA <1ng/ml) was 65.6% for SO and 67.2% for MC (P = 0.212). Both therapies achieve >95% of effective androgen suppression (testosterone <50ng/dL). Time to castrate-resistance was similar (18 vs 16 months, P = 0.097), with comparative overall survival (42 vs. 38.5 months, P = 0.058) and prostate cancer mortality (80.1 vs. 75.9%, P = 0.328). Similarly, no difference was observed for the 4 AE profiles between SO and MC respectively; change in Haemoglobin (-0.75 vs. -1.0g/dL, P = 0.302), newly diagnosed Diabetes mellitus (4.6 vs. 2.9%, P = 0.281), control measured by HbA1c (0.2 vs. 0.25%, P = 0.769), coronary artery disease events (9.9 vs. 12.9%, P = 0.376) and skeletal-related fractures (9.3 vs. 7.3%, P = 0.476). After adjusting for varying governmental subsidies and inflation rates, the median cost of SO was $5275, compared to MC of $9185.80. CONCLUSION Both SO and MC have similar oncological outcomes and AE profiles. However, SO remains a much more cost-effective form of ADT for the long-term treatment of mPCa patients.

A lifestyle intervention of weight loss via a low-carbohydrate diet plus walking to reduce metabolic disturbances caused by androgen deprivation therapy among prostate cancer patients: carbohydrate and prostate study 1 (CAPS1) randomized controlled trial. Prostate Cancer Prostatic Dis 2019; 22:428-437. [PMID: 30664736 DOI: 10.1038/s41391-019-0126-5] [Citation(s) in RCA: 37] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2018] [Revised: 12/23/2018] [Accepted: 01/06/2019] [Indexed: 01/26/2023]
Abstract
PURPOSE The objective of this study was to test a low-carbohydrate diet (LCD) plus walking to reduce androgen deprivation therapy (ADT)-induced metabolic disturbances. MATERIALS AND METHODS This randomized multi-center trial of prostate cancer (PCa) patients initiating ADT was designed to compare an LCD (≤20g carbohydrate/day) plus walking (≥30 min for ≥5 days/week) intervention vs. control advised to maintain usual diet and exercise patterns. Primary outcome was change in insulin resistance by homeostatic model assessment at 6 months. To detect 20% reduction in insulin resistance, 100 men were required. The study was stopped early after randomizing 42 men due to slow accrual. Secondary outcomes included weight, body composition, lipids, and prostate-specific antigen (PSA). Changes from baseline were compared between arms using rank-sum tests. RESULTS At 6 months, LCD/walking reduced insulin resistance by 4% vs. 36% increase in control (p = 0.13). At 3 months, vs. control, LCD/walking arm significantly lost weight (7.8kg; p<0.001), improved insulin resistance (↑36%; p = 0.015), hemoglobin A1c (↓3.3%; p = 0.01), high-density lipoprotein (HDL) (↑13%; p = 0.004), and triglyceride (↓37%; p = 0.036). At 6 months, weight loss (10.6kg; p<0.001) and HDL (↑27%; p = 0.003) remained significant. LCD/walking preserved total body bone mineral count (p = 0.025), reduced fat mass (p = 0.002), lean mass (p = 0.036), and percent body fat (p = 0.004). There were no differences in PSA. Limitations include the effect of LCD, weight loss vs. walking instruction are indistinguishable, and small sample size. CONCLUSIONS In an underpowered study, LCD/walking did not improve insulin sensitivity at 6 months. Given most secondary outcomes were improved at 3 months with some remaining improved at 6 months and a secondary analysis showed that LCD/walking reduced insulin resistance over the study, supporting future larger studies of LCD/walking intervention to reduce ADT-induced disturbances.

Abstract
BACKGROUND Prostate cancer has the highest incidence of any type of cancer in Germany; an estimated 67 000 new diagnoses of prostate cancer will be made in 2016. In the current German S3 guideline for the treatment of prostate cancer, radiotherapy-sometimes in combination with androgen deprivation therapy (ADT)-is one of the two recommended options for treatment with curative intent (the other is radical prostatectomy). There have been many publications on this subject, yet it is still often unclear in routine practice how ADT should be administered, and for how long. METHODS This review is based on publications retrieved by a selective literature search, with special attention to controlled trials. RESULTS For low risk patients, radiotherapy without ADT is indicated (evidence level 1). Patients with localized prostate cancer and an intermediate risk benefit from radiotherapy combined with a four-to-six-month course of ADT. In this situation, a higher radiation dose might be an effective substitute for ADT (evidence level 1-2). For patients at high risk, radiotherapy combined with long-term hormonal treatment is the standard therapy, as it significantly improves all oncological end points (evidence level 1). For example, in the largest randomized and controlled trial, this form of treatment reduced cancer-specific mortality from 19% to 9% . Higher radiation doses of 66-74 Gy and longer ADT can improve local control at the cost of increased urethral toxicity. CONCLUSION Androgen deprivation combined with external beam radiotherapy is a curative standard option for patients with prostate cancer who are at high risk of recurrence. The modern radiotherapeutic techniques that are now available, such as intensity-modulated radiotherapy, enable a further improvement of the risk/benefit ratio.

Abstract
Prostate cancer (PCa) and type two diabetes mellitus (T2DM) are both increasing prevalent conditions and often occur concurrently. However, the relationship between the two is more complex than just two prevalent conditions co-existing. This review systematically explores the literature around the interplay between the two conditions. It covers the impact of pre-existing T2DM on PCa incidence, grade and stage, as well as exploring the impact of T2DM on PCa outcomes and mortality and the interaction between T2DM and PCa treatments.

Abstract
The past decade has brought increased awareness of the potential adverse effects of androgen deprivation therapy (ADT) in men with prostate cancer. Arguably the most important and controversial of these is the increased risk of cardiovascular morbidity and mortality. Although multiple observational studies have shown that men treated with ADT are at increased risk of developing atherosclerotic cardiovascular disease, our understanding of the biological mechanisms that might underlie this phenomenon is still evolving. In this review, we discuss some of the mechanisms that have been proposed to date, including ADT-induced metabolic changes that promote the development and progression of atherosclerotic plaques as well as direct local effects of hormonal factors on plaque growth, rupture and thrombosis.

Abstract
We investigated the fracture risk after androgen deprivation therapy (ADT) for prostate cancer in the Chinese population. All Chinese prostate cancer patients who were treated primarily by radical prostatectomy or radiotherapy, with or without further ADT, from year 2000 to 2009 were reviewed. We compared the fracture risk in patients who were given ADT (ADT group) with those who were not given any ADT (non-ADT group). Potential risk factors including age, diabetes mellitus, hypertension, hyperlipidemia, ischemic heart disease and performance status were reviewed. The fracture risk was analyzed with Kaplan-Meier and multivariate Cox regression analyses. Our cohort consisted of 200 patients in the non-ADT group and 252 patients in the ADT group. The ADT group was shown to have higher fracture risk (p = 0.036) upon Kaplan-Meier analysis. Upon multivariate Cox regression analyses, diabetes mellitus (HR 4.39, 95% CI 1.08-17.83, p = 0.039), poor performance status (HR 3.14, 95% CI 1.24-8.00, p = 0.016) and the use of ADT (HR 4.89, 95% CI 1.03-23.17, p = 0.045) were associated with increased fracture risk. In conclusion, the fracture risk should be considered while deciding on ADT in Chinese men, especially in diabetic patients with poor performance status.
