Abstract
Background Less is known about the sexual life and information seeking of Chinese patients with prostate cancer (PCa) after androgen deprivation therapy (ADT) treatment. Aim To identify the experiences of sex and information needs among Chinese patients with PCa after ADT treatment. Methods This qualitative study included 15 Chinese patients with PCa in urology inpatient wards, selected via a purposive sampling method. Semistructured interviews were conducted face-to-face or by telephone regarding sexual experiences and information needs after ADT treatment. Outcomes Themes and subthemes were assessed among patients with PCa. Results Two themes and 5 subthemes emerged from the interview data. The first theme was "altered sexual life and attitude" with 3 subthemes: (1) undesirable sexual function and altered sexuality, (2) sexual attitudes and sociocultural cognition, and (3) behavior adjustment and intimacy. The second theme was "scarce information sources" with 2 subthemes: (1) uncertainty and lack of information support and (2) barriers to access sexual information. Clinical Implications The present findings suggest that the following may help patients with PCa manage treatment and develop appropriate sexual attitudes: a tailored sexual health education program, well-equipped consultations rooms, and information delivery innovations. Strengths and Limitations Strengths of this study included adding unique evidence among patients with PCa within an Asian context to reveal the understudied topic of sexual health and information needs after ADT treatment. This study was limited in being representative of all Chinese patients with PCa, with different marital statuses, treatment therapies, sexual orientations, and barriers of information seeking. Conclusion Sexual life and attitude among patients with PCa were affected by their sociocultural cognition and ADT treatment, and most patients received insufficient information and sexual health education from health care providers.

Health-Related Quality of Life Assessment in Prostate Cancer Patient Undergoing Androgen Deprivation Therapy: Real-World Experience in the READT Study. World J Mens Health 2024; 42:449-459. [PMID: 37853536 PMCID: PMC10949021 DOI: 10.5534/wjmh.230042] [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: 02/24/2023] [Revised: 05/22/2023] [Accepted: 06/08/2023] [Indexed: 10/20/2023] Open
Abstract
PURPOSE To investigate the effect of androgen deprivation therapy (ADT) on health-related quality of life (HRQOL) in Asian men with all stages of prostate cancer. MATERIALS AND METHODS READT (real-life evaluation of the effect of ADT in prostate cancer patients in Asia) was a multi-center, prospective observational study involving six sites across four Asian populations. We enrolled eligible prostate cancer patients, who opted for ADT alone or in combination without prior neoadjuvant or adjuvant ADT within 12 months. The EuroQoL-5 dimensions, 5 level scale (EQ-5D-5L) utility index scores and visual analog scale (VAS) were evaluated at baseline, month 6 and month 12. RESULTS A total of 504 patients were recruited into READT between September 2016 and May 2020 with 52.9% diagnosed with metastatic prostate cancer. The EQ-5D-5L was evaluable in 442/504 (87.7%) of patients. Overall baseline EQ-5D-5L utility index score was 0.924 (interquartile range [IQR] 0.876-1.000). We observed a statistically significant difference in baseline EQ-5D-5L utility index score among different populations with a median EQ-5D-5L utility index score of 1 for Taiwan & Hong Kong, 0.897 for China and 0.838 for Malaysia. Similar trend was observed throughout multiple treatment time-points. Stage IV prostate cancer were significantly associated with a lower baseline EQ-5D-5L utility index score compared to stage I-III prostate cancer, producing a median disutility value of -0.080. Participants had a high median VAS (80, IQR 70-90), indicating good overall health on average during ADT initiation. CONCLUSIONS The study highlights the differences in health state utility index scores among various Asian prostate cancer patients receiving ADT at real-world setting. Our findings will be informative and useful in cost-effectiveness evaluation and policy decision making.

Prostate cancer management in Southeast Asian countries: a survey of clinical practice patterns. Ther Adv Med Oncol 2024; 16:17588359231216582. [PMID: 38249332 PMCID: PMC10798109 DOI: 10.1177/17588359231216582] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Accepted: 07/19/2023] [Indexed: 01/23/2024] Open
Abstract
Background Prostate cancer (PC) has a serious public health impact, and its incidence is rising due to the aging population. There is limited evidence and consensus to guide the management of PC in Southeast Asia (SEA). We present real-world data on clinical practice patterns in SEA for advanced PC care. Method A paper-based survey was used to identify clinical practice patterns and obtain consensus among the panelists. The survey included the demographics of the panelists, the use of clinical guidelines, and clinical practice patterns in the management of advanced PC in SEA. Results Most panelists (81%) voted prostate-specific antigen (PSA) as the most effective test for early PC diagnosis and risk stratification. Nearly 44% of panelists agreed that prostate-specific membrane antigen positron emission tomography-computed tomography imaging for PC diagnostic and staging information aids local and systemic therapy decisions. The majority of the panel preferred abiraterone acetate (67%) or docetaxel (44%) as first-line therapy for symptomatic mCRPC patients. Abiraterone acetate (50%) is preferred over docetaxel as a first-line treatment in metastatic castration-sensitive prostate cancer patients with high-volume disease. However, the panel did not support the use of abiraterone acetate in non-metastatic castration-resistant prostate cancer (nmCRPC) patients. Apalutamide (75%) is the preferred treatment option for patients with nmCRPC. The cost and availability of modern treatments and technologies are important factors influencing therapeutic decisions. All panelists supported the use of generic versions of approved therapies. Conclusion The survey results reflect real-world management of advanced PC in a SEA country. These findings could be used to guide local clinical practices and highlight the financial challenges of modern healthcare.

Novel hormonal therapies in the management of advanced prostate cancer: extrapolating Asian findings to Southeast Asia. BMC Urol 2023; 23:4. [PMID: 36609251 PMCID: PMC9824980 DOI: 10.1186/s12894-022-01156-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2022] [Accepted: 12/02/2022] [Indexed: 01/09/2023] Open
Abstract
There is a paucity of information on the use of novel hormonal agents in Southeast Asian patients. We reviewed the clinical roles of novel hormonal therapy (NHT), namely abiraterone acetate (AA), enzalutamide, apalutamide and darolutamide, in the management of advanced prostate cancer, and data on its use in Asian patients, in order to extrapolate these findings to the Southeast Asian patient population. There are some differences in the molecular features between the NHTs, which influenced their respective permeabilities through the blood-brain barrier. The Asian sub-analyses of the landmark studies of each NHT were limited. The primary endpoints of the Asian sub-analyses generally reflect the efficacy outcomes of the respective landmark study. Hypertension, fatigue, musculoskeletal disorders, rash, and hot flushes were among the common toxicities observed in Asian patients. Real-world data on AA in the Asian setting is favourable, but data is limited for enzalutamide, apalutamide and darolutamide. Based on the sub-analyses and real-world data, the efficacy and safety of NHTs in the Asian patients showed a similar trend to the respective landmark studies. The lack of clinical trials in the Southeast Asian region hampers the ability to make a robust conclusion on any specific efficacy or safety differences that may be present; clinicians must assume that the broader Asian sub-analyses and real-world data reflects Southeast Asian patients' outcomes.

Abstract
All aspects of prostate cancer evolution are closely related to androgen levels and the status of the androgen receptor (AR). Almost all treatments target androgen metabolism pathways and AR, from castration-sensitive prostate cancer (CSPC) to castration-resistant prostate cancer (CRPC). Alterations in androgen metabolism and its response are one of the main reasons for prostate cancer drug resistance. In this review, we will introduce androgen metabolism, including how the androgen was synthesized, consumed, and responded to in healthy people and prostate cancer patients, and discuss how these alterations in androgen metabolism contribute to the resistance to anti-androgen therapy.

Abstract
The most recent version of the European Society for Medical Oncology (ESMO) Clinical Practice Guidelines for the diagnosis, treatment and follow-up of prostate cancer was published in 2020. It was therefore decided, by both the ESMO and the Singapore Society of Oncology (SSO), to convene a special, virtual guidelines meeting in November 2021 to adapt the ESMO 2020 guidelines to take into account the differences associated with the treatment of prostate cancer in Asia. These guidelines represent the consensus opinions reached by experts in the treatment of patients with prostate cancer representing the oncological societies of China (CSCO), India (ISMPO), Japan (JSMO), Korea (KSMO), Malaysia (MOS), Singapore (SSO) and Taiwan (TOS). The voting was based on scientific evidence and was independent of the current treatment practices and drug access restrictions in the different Asian countries. The latter were discussed when appropriate. The aim is to provide guidance for the optimisation and harmonisation of the management of patients with prostate cancer across the different regions of Asia.

The slope associated with nadir prostate-specific antigen is prognostically significant in men with hormone-sensitive prostate cancer after primary androgen deprivation therapy. Cancer Med 2022; 11:3251-3259. [PMID: 35307955 PMCID: PMC9468434 DOI: 10.1002/cam4.4685] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Revised: 03/04/2022] [Accepted: 03/08/2022] [Indexed: 11/11/2022] Open
Abstract
BACKGROUND Prognostic indicators based on the initial prostate-specific antigen (PSA) levels, nadir PSA, and time to PSA nadir were calculated to evaluate prognosis after primary androgen deprivation therapy (PADT), as these have been reported in very few studies. We attempted to evaluate the prognostic role of the slope associated with nadir PSA in patients treated with PADT. METHODS A total of 107 patients who were treated with PADT from 2015 to 2019 were reviewed. The Kaplan-Meier method and Cox regression model were used to analyze the prognostic significance of the slope associated with nadir PSA in predicting progression-free survival (PFS) and overall survival (OS). RESULTS After PADT, the median follow-up duration was 40.1 months; 66 patients (61.7%) had disease progression, and 33 patients (30.8%) died. In the univariate analysis, T stage, N stage, nadir PSA, time to PSA nadir, nadir PSA declining slope (nPSA-DS), nadir PSA percentage declining slope (nPSA-PDS), and nadir PSA line slope (nPSA-LS) were significant predictors for PFS and OS. The multivariate analysis showed that a higher nPSA-DS (> - 0.74) and lower PSA nadir (≤0.16 ng/ml) were independent predictors for prolonged survival. The significance of nPSA-DS and nPSA was supported by the analysis of nPSA-DS and nPSA as time-dependent covariates. The combined analyses demonstrated that patients with a higher nPSA-DS and lower PSA nadir had the best PFS and OS. CONCLUSIONS The slope associated with the nadir PSA of nPSA-DS was a significant independent predictor for patients treated with PADT. Nadir PSA and nPSA-DS have a synergistic effect on prognosis.

Abstract
Prostate cancer is the third most common cancer in Malaysia with the lifetime risk of 1 in 117 men. Here, we initiated a longitudinal Malaysia Prostate Cancer (M‐CaP) Study to investigate the clinical and tumour characteristics, treatment patterns as well as disease outcomes of multi‐ethnic Asian men at real‐world setting. The M‐CaP database consisted of 1839 new patients with prostate cancer diagnosed between 2016 and 2018 from nine public urology referral centres across Malaysia. Basic demographic and clinical parameters, tumour characteristics, primary treatment, follow‐up and vital status data were retrieved prospectively from the hospital‐based patients’ case notes or electronic medical records. Primary endpoints were overall survival (OS) and biochemical progression‐free survival (bPFS). The median age at diagnosis of M‐CaP patients was 70 years (interquartile range, IQR 65–75). Majority of patients were Chinese (831, 45.2%), followed by Malays (704, 38.3%), Indians (124, 6.7%) and other races (181, 9.8%). The median follow‐up for all patients was 23.5 months (IQR 15.9–33.6). Although 58.1% presented with late‐stage cancer, we observed ethnic and geographic disparities in late‐stage prostate cancer diagnosis. Curative radiotherapy and primary androgen deprivation therapy were the most common treatment for stage III and stage IV diseases, respectively. The median OS and bPFS of stage IV patients were 40.1 months and 19.2 months (95% CI 17.6–20.8), respectively. Late stage at presentation remains a challenge in multi‐ethnic Asian men. Early detection is imperative to improve treatment outcome and survival of patients with prostate cancer.

Abstract
The number of newly diagnosed prostate cancer cases varies across Asia, with higher mortality-to-incidence ratio reported in developing nations. Androgen deprivation therapy (ADT), alone or in combination, remains the mainstay of first-line treatment for advanced prostate cancer. Key findings of extensive research and randomized controlled trials have shaped current clinical practice and influenced clinical guideline recommendations. We describe here the recent trend of ADT in newly diagnosed prostate cancer for Asia focusing on Japan (high-income country) and Malaysia (middle-income country) based on the Asian Prostate Cancer (A-CaP) Study. The combination of radiotherapy and ADT or ADT alone was common in patients with intermediate-to-high risk localized and locally advanced disease. For metastatic prostate cancer, maximum androgen blockade (gonadotrophin-releasing hormone [GnRH] agonist/antagonist plus antiandrogen) was prevalent among the Japanese patients while primary ADT alone with GnRH agonist/antagonist was widely practiced in the Malaysian cohort. Upfront combined therapy (ADT plus docetaxel or androgen receptor pathway inhibitor) has significantly improved the outcomes of patients with metastatic castration-naïve prostate cancer. Its application, however, remains low in our cohorts due to patients' financial capacity and national health insurance coverage. Early detection remains the cornerstone in prostate cancer control to improve treatment outcome and patient survival.
