Significance of androgen-deprivation therapy for intermediate- and high-risk prostate cancer treated with high-dose radiotherapy: A literature review. Int J Urol 2024; 31:1068-1079. [PMID: 39021064 DOI: 10.1111/iju.15535] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [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.

Abstract
This fourth edition of the Japanese Clinical Practice Guidelines for Prostate Cancer 2023 is compiled. It was revised under the leadership of the Japanese Urological Association, with members selected from multiple academic societies and related organizations (Japan Radiological Society, Japanese Society for Radiation Oncology, the Department of EBM and guidelines, Japan Council for Quality Health Care (Minds), Japanese Society of Pathology, and the patient group (NPO Prostate Cancer Patients Association)), in accordance with the Minds Manual for Guideline Development (2020 ver. 3.0). The most important feature of this revision is the adoption of systematic reviews (SRs) in determining recommendations for 14 clinical questions (CQs). Qualitative SRs for these questions were conducted, and the final recommendations were made based on the results through the votes of 24 members of the guideline development group. Five algorithms based on these results were also created. Contents not covered by the SRs, which are considered textbook material, have been described in the general statement. In the general statement, a literature search for 14 areas was conducted; then, based on the general statement and CQs of the Japanese Clinical Practice Guidelines for Prostate Cancer 2016, the findings revealed after the 2016 guidelines were mainly described. This article provides an overview of these guidelines.

Accrual and statistical power failure in published adjuvant phase III oncology trials: a comprehensive analysis from 2013 to 2023. ESMO Open 2024; 9:103603. [PMID: 38925083 PMCID: PMC11255358 DOI: 10.1016/j.esmoop.2024.103603] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2024] [Revised: 05/19/2024] [Accepted: 05/20/2024] [Indexed: 06/28/2024] Open
Abstract
BACKGROUND In a competitive landscape with many ongoing adjuvant randomised controlled trials (RCTs), the prevalence of trials that failed to recruit their targeted sample size and were inadequately powered is unclear. The aims of the study are (i) to determine the percentage of trials with accrual and statistical power failure and (ii) to evaluate their potential impact on the drug development process. MATERIALS AND METHODS A systematic review was carried out to identify adjuvant phase III oncology RCTs reported between 2013 and 2023 across all solid tumours. No restrictions were applied regarding the type of intervention or journal of publication. The percentage of trials with accrual failure and power failure was estimated as well as their association with the efficacy endpoints. Logistic regression models were used to estimate the odds ratio (OR) and its 95% confidence interval (CI). RESULTS A total of 282 RCTs met the inclusion criteria with a median sample size of 661 patients and a median accrual period of 4.3 years. Most of these studies were superiority trials (83.0%). Accrual failure was observed in 22.0% of the studies, finishing recruitment without achieving the targeted sample size. Overall, 39.7% of the studies experienced power failure, having less power than specified in the protocol at the date of the read-out. Among superiority RCTs evaluating intermediate survival endpoints, only 31.1% presented statistically significant results. Trials with power failure were less likely to present statistically significant results (37.9% versus 21.9%, P = 0.04). The association was consistent across all cancer types. In the subset of non-inferiority trials, 35.0% formally demonstrated non-inferiority of the experimental arm. CONCLUSIONS Nearly 40% of adjuvant phase III RCTs experienced power failure, and the reduction in power significantly impacted the final study results. There is a need for procedural refinements in the design and implementation of future adjuvant RCTs to mitigate these fallacies.

Neoadjuvant versus Concurrent Androgen Deprivation Therapy in Localized Prostate Cancer Treated with Radiotherapy: A Systematic Review of the Literature. Cancers (Basel) 2023; 15:3363. [PMID: 37444473 DOI: 10.3390/cancers15133363] [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: 05/26/2023] [Revised: 06/21/2023] [Accepted: 06/23/2023] [Indexed: 07/15/2023] Open
Abstract
BACKGROUND There is an ongoing debate on the optimal sequencing of androgen deprivation therapy (ADT) and radiotherapy (RT) in patients with localized prostate cancer (PCa). Recent data favors concurrent ADT and RT over the neoadjuvant approach. METHODS We conducted a systematic review in PubMed, EMBASE, and Cochrane Databases assessing the combination and optimal sequencing of ADT and RT for Intermediate-Risk (IR) and High-Risk (HR) PCa. FINDINGS Twenty randomized control trials, one abstract, one individual patient data meta-analysis, and two retrospective studies were selected. HR PCa patients had improved survival outcomes with RT and ADT, particularly when a long-course Neoadjuvant-Concurrent-Adjuvant ADT was used. This benefit was seen in IR PCa when adding short-course ADT, although less consistently. The best available evidence indicates that concurrent over neoadjuvant sequencing is associated with better metastases-free survival at 15 years. Although most patients had IR PCa, HR participants may have been undertreated with short-course ADT and the absence of pelvic RT. Conversely, retrospective data suggests a survival benefit when using the neoadjuvant approach in HR PCa patients. INTERPRETATION The available literature supports concurrent ADT and RT initiation for IR PCa. Neoadjuvant-concurrent-adjuvant sequencing should remain the standard approach for HR PCa and is an option for IR PCa.

Clinical significance of IDC-P as predictive factor after intensity-modulated radiation therapy. Cancer Sci 2022; 113:2425-2433. [PMID: 35514196 PMCID: PMC9277254 DOI: 10.1111/cas.15392] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2022] [Revised: 04/20/2022] [Accepted: 04/30/2022] [Indexed: 11/30/2022] Open
Abstract
The clinical significance of intraductal carcinoma of the prostate (IDC‐P) in men with nonmetastatic prostate cancer (PCa) treated with high‐dose external‐beam radiation therapy remains unclear. The aim of this study was to evaluate the impact of IDC‐P in men who received intensity‐modulated radiation therapy (IMRT) for nonmetastatic PCa. All patients with high‐risk (H‐R) and very high–risk (VH‐R) PCa who received IMRT between September 2000 and December 2013 at our institution were analyzed retrospectively. We re‐reviewed biopsy cores for the presence of IDC‐P. Treatment consisted of IMRT (median: 78 Gy at 2 Gy per fraction) plus 6‐month neoadjuvant hormonal therapy (HT). In total, 154 consecutive patients with H‐R and VH‐R PCa were analyzed. Intraductal carcinoma of the prostate was present in 27.9% (n = 43). The median follow‐up period was 8.4 years. The 10‐year PCa‐specific survival, biochemical failure (BF), clinical failure, and castration‐resistant PCa rates were 90.0%, 47.8%, 27.5%, and 24.5% in patients with IDC‐P, and 96.6%, 32.6%, 10.8%, and 7.0% in those without IDC‐P, respectively (p = 0.12, 0.04, 0.0031, and 0.012, respectively). In multivariable analysis, IDC‐P was not identified as an independent predictive factor for BF (p = 0.26). The presence of IDC‐P was correlated with a significantly higher incidence of disease progression in men with H‐R and VH‐R PCa who received IMRT, although it was not identified as an independent predictive factor for BF. Further investigations are needed to determine the significance of IDC‐P as an independent predictive factor for survival outcomes.

Abstract
The problems with anticancer therapy are resistance and toxicity. From 3000 Cisplatin derivatives tested as antitumor agents, most of them have been rejected, due to toxicity. The aim of current study is the comparison of therapeutic combinations of the currently applied in clinical practice: Cisplatin, Carboplatin, Oxaliplatin, Nedaplatin, Lobaplatin, Heptaplatin, and Satraplatin. The literature data show that the strategies for the development of platinum anticancer agents and bypassing of resistance to Cisplatin derivatives and their toxicity are: combination therapy, Pt IV prodrugs, the targeted nanocarriers. The very important strategy for the improvement of the antitumor effect against different cancers is synergistic combination of Cisplatin derivatives with: (1) anticancer agents-Fluorouracil, Gemcitabine, Cytarabine, Fludarabine, Pemetrexed, Ifosfamide, Irinotecan, Topotecan, Etoposide, Amrubicin, Doxorubicin, Epirubicin, Vinorelbine, Docetaxel, Paclitaxel, Nab-Paclitaxel; (2) modulators of resistant mechanisms; (3) signaling protein inhibitors-Erlotinib; Bortezomib; Everolimus; (4) and immunotherapeutic drugs-Atezolizumab, Avelumab, Bevacizumab, Cemiplimab, Cetuximab, Durvalumab, Erlotinib, Imatinib, Necitumumab, Nimotuzumab, Nivolumab, Onartuzumab, Panitumumab, Pembrolizumab, Rilotumumab, Trastuzumab, Tremelimumab, and Sintilimab. An important approach for overcoming the drug resistance and reduction of toxicity of Cisplatin derivatives is the application of nanocarriers (polymers and liposomes), which provide improved targeted delivery, increased intracellular penetration, selective accumulation in tumor tissue, and enhanced therapeutic efficacy. The advantages of combination therapy are maximum removal of tumor cells in different phases; prevention of resistance; inhibition of the adaptation of tumor cells and their mutations; and reduction of toxicity.

The effectiveness of high-dose-rate brachytherapy with external beam radiotherapy for clinically locally advanced and node-positive prostate cancer: long-term results of a retrospective study. Int J Clin Oncol 2021; 26:2310-2317. [PMID: 34494172 DOI: 10.1007/s10147-021-02023-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2021] [Accepted: 08/24/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND No standard treatment exists for locally advanced prostate cancer (PC). This study evaluated the long-term treatment outcomes and toxicity in patients with clinically locally advanced and/or lymph node (LN)-positive PC who underwent high-dose-rate brachytherapy (HDR-BT) with external beam radiotherapy (EBRT). METHODS The treatment outcomes and toxicities of 152 patients with PC who underwent HDR-BT with EBRT and had at least 2 years of observation were examined. The treatment dose was 19- and 13-Gy HDR-BT in two and single fractions, respectively, both combined with external irradiation of 46 Gy in 23 fractions. Long-term androgen deprivation therapy (ADT) for patients harboring very high-risk tumors was used in combination. RESULTS The median observation period was 59.7 (24.4-182.1) months. The 5-year prostate cancer-specific and recurrence-free (RFS) survival rates were 99.0% and 91.8%, respectively, with only two PC mortalities. When 5-year RFS was examined for each parameter, RFS was significantly lower in pre-radiotherapy (pre-RT) prostate-specific antigen (PSA) > 0.5 ng/mL (77.1%; p = 0.008), and presence of LN metastasis (68.1%; p = 0.017). Multivariable analysis demonstrated that pre-RT PSA (HR, 4.68; 95% CI, 1.39-15.67; p = 0.012) and presence of LN metastasis (HR, 4.70; 95% CI, 1.24-17.74; p = 0.022) were independent recurrence predictors. The 5-year cumulative incidence rate of grade ≥ 2 toxicities in genitourinary and gastrointestinal tracts were 15.4% and 1.3%, respectively. CONCLUSIONS HDR-BT combined with EBRT and long-term ADT shows promising disease control and tolerant toxicities for clinically locally advanced and LN-positive PC.

Abstract
Background We evaluated patient‐reported outcomes (PRO) during neoadjuvant androgen deprivation therapy (ADT) plus external beam radiation therapy (EBRT) followed by either adjuvant continuous ADT (CADT) or intermittent ADT (IADT) for patients with locally advanced prostate cancer (Pca). Methods A multicenter, randomized phase III trial enrolled 303 patients with locally advanced Pca. The patients were treated with 6 months (M) of ADT followed by 72 Gy of EBRT, and were randomly assigned to CADT or IADT after 14 M. The PROs were evaluated at sic points: baseline, 6 M, 8 M, 14 M, 20 M, and 38 M using FACT‐P questionnaires and EPIC urinary, bowel, and sexual bother subscales. Results The FACT‐P total scores were significantly better (p < 0.05) in IADT versus CADT at 20 M (121.6 vs.115.4) and at 38 M (119.9 vs. 115.2). The physical well‐being scores (PWB) were significantly better (p < 0.05) in IADT versus CADT at 38 M (25.4 vs. 24.0). The functional scores were significantly better in IADT than those in CADT at 14 M (20.2 vs18.7, p < 0.05) and at 20 M (21.0 vs.18.9, p < 0.05). Conclusion The PRO was significantly favorable in IADT on FACT‐P total score at 20 M and 38 M, PWB and functional scores at 38 M.
