Significance of androgen-deprivation therapy for intermediate- and high-risk prostate cancer treated with high-dose radiotherapy: A literature review. Int J Urol 2024. [PMID: 39021064 DOI: 10.1111/iju.15535] [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: 05/29/2024] [Accepted: 07/02/2024] [Indexed: 07/20/2024]
Abstract
The real-world benefits of adding androgen-deprivation therapy (ADT) and its optimal duration when combined with current standard high-dose radiation therapy (RT) remain unknown. We aimed to assess the efficacy of and toxicities associated with ADT in the setting of combination with high-dose RT for intermediate-risk (IR) and high-risk (HR) prostate cancer (PCa). This article is a modified and detailed version of the commentary on Clinical Question 8 described in the Japanese Clinical Practice Guidelines for Prostate Cancer (ver. 2023). A qualitative systematic review was performed according to the Minds Guide. All relevant published studies between September 2010 and August 2020, which assessed the outcomes of IR or HR PCa treated with high-dose RT, were screened using two databases (PubMed and ICHUSHI). A total of 41 studies were included in this systematic review, mostly consisting of retrospective studies (N = 34). The evidence basically supports the benefit of adding ADT to high-dose RT to improve tumor control. Regarding IR populations, many studies suggested the existence of a subgroup for which adding ADT had no impact on either overall survival or the BF-free duration. On the other hand, regarding HR populations, several studies suggested the positive impact of adding ADT for ≥1 year on overall survival. Adding ADT increases not only the risk of sexual dysfunction but also that of cardiovascular toxicities or bone fracture. Although the benefit of adding ADT was basically suggested for both IR and HR populations, further investigations are warranted to identify subgroups of patients for whom ADT has no benefit, as well as the appropriate duration of ADT for those who do derive benefit.

Risks of metabolic diseases and androgen deprivation therapy for prostate cancer in a Chinese population: a prospective multi-centre cohort study. Int Urol Nephrol 2022; 54:993-1000. [PMID: 35217907 DOI: 10.1007/s11255-022-03151-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2022] [Accepted: 02/06/2022] [Indexed: 10/19/2022]
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.

Favorable prognosis of patients who received adjuvant androgen deprivation therapy after radiotherapy achieving undetectable levels of prostate-specific antigen in high- or very high-risk prostate cancer. PLoS One 2021; 16:e0248461. [PMID: 33711055 PMCID: PMC7954315 DOI: 10.1371/journal.pone.0248461] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2020] [Accepted: 02/27/2021] [Indexed: 11/17/2022] Open
Abstract
Introduction To determine the prognostic significance of long-term adjuvant androgen deprivation therapy (A-ADT) over 1 year in achieving undetectable levels of prostate-specific antigen (PSA) less than 0.001 ng/mL in prostate cancer patients with high- or very high-risk prostate cancer who underwent radiotherapy (RT). Materials and methods A total of 197 patients with prostate cancer received RT, with a follow-up of ≥12 months. Biochemical failure was defined as PSA ≥nadir + 2 ng/mL after RT. We analyzed clinical outcomes, including survival, failure patterns, and prognostic factors affecting outcomes. Results Biochemical failure-free survival (BCFFS), clinical failure-free survival, distant metastasis-free survival, cancer-specific survival, and overall survival (OS) rates at 5 years were 91.1%, 95.4%, 96.9%, 99.5%, and 89.1%, respectively. Administration of long-term A-ADT significantly predicted favorable BCFFS (p = 0.027) and OS (p < 0.001) in multivariate analysis. Nadir PSA ≤0.001 ng/mL was an independent prognostic factor for BCFFS (p = 0.006) and OS (p = 0.021). The use of long-term A-ADT significantly affected nadir PSA ≤0.001 ng/mL (p < 0.001). The patients with A-ADT for 1 year or longer had better BCFFS or OS than those for less than 1 year or those without A-ADT (p < 0.001). The best prognosis was demonstrated in patients treated with long-term A-ADT and nadir PSA ≤0.001 ng/mL in BCFFS (p < 0.001). Conclusion The addition of long-term A-ADT over 1 year to RT demonstrated good treatment outcomes in patients with locally advanced prostate cancer. Achieving a nadir PSA value ≤0.001 ng/mL using combination therapy with RT and A-ADT is a powerful clinical predictor of treatment outcomes.

Should We Reconsider the Necessity of a Refinement of Prostate Cancer Risk Classification and Radiotherapy Treatment Strategy? Experiences from a Retrospective Analysis of Data from a Single Institution. J Clin Med 2020; 10:jcm10010110. [PMID: 33396923 PMCID: PMC7795563 DOI: 10.3390/jcm10010110] [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: 12/02/2020] [Revised: 12/20/2020] [Accepted: 12/26/2020] [Indexed: 12/03/2022] Open
Abstract
Background: Radiation therapy has undergone significant technical development in the past decade. However, the complex therapy of intermediate-risk patients with organ-confined prostate carcinoma still poses many questions. Our retrospective study investigated the impact of selected components of the treatment process including radiotherapy, hormone deprivation, risk classification, and patients’ response to therapy. Methods: The impact of delivered dose, planning accuracy, duration of hormone deprivation, risk classification, and the time to reach prostate-specific antigen (PSA) nadir state were analyzed among ninety-nine individuals afflicted with organ-confined disease. Progression was defined as a radiological or biochemical relapse within five years from radiotherapy treatment. Results: We found that 58.3% of the progressive population consisted of intermediate-risk patients. The progression rate in the intermediate group was higher (21.9%) than in the high-risk population (12.1%). Dividing the intermediate group, according to the International Society of Urological Pathology (ISUP) recommendations, resulted in the non-favorable subgroup having the highest rate of progression (33.3%) and depicting the lowest percentage of progression-free survival (66.7%). Conclusion: Extended pelvic irradiation on the regional lymph nodes may be necessary for the ISUP Grade 3 subgroup, similarly to the high-risk treatment. Therapy optimization regarding the intermediate-risk population based on the ISUP subgrouping suggestions is highly recommended in the treatment of organ-confined prostate cancer.

Abstract
OBJECTIVES To explore the four Rs of radiobiology (Repair, Reoxygenation, Reassortment, and Repopulation) as a means to understand the effects of ionising radiation on biological tissue and subsequently as the basis for conventional fractionated treatment schedules. These radiobiological principles will form a rationale for combined regimens in prostate cancer treatment involving androgen deprivation therapy and radiation therapy and the associated toxicities of this approach will be discussed. DATA SOURCES Electronic databases including CINAHL, MEDLINE, Scopus, professional websites, books and grey literature were searched using Google Scholar. CONCLUSION It is important for nurses to understand the four Rs of radiobiology to grasp the effects of ionising radiation on biological tissue as the basis for conventional fractionated treatment schedules in prostate cancer. Men can experience a sequalae of physical and psychological side effects of treatment that can negatively impact quality of life. IMPLICATIONS FOR NURSING PRACTICE Men can experience a range of unmet supportive care needs particularly related to informational, sexual, and psychological needs. For men affected by prostate cancer opting for radiation therapy (+/-) androgen deprivation therapy, nurses should ask targeted questions based on the Common Terminology Criteria for Adverse Events related to urinary and bowel function, potency and fatigue, and sexual health. We also recommend the use of holistic needs assessments to tailor self-management care plans. Evidence-based self-management advice should be provided in response to each man's unique needs.
