Purpose: The addition of androgen receptor pathway inhibitors (ARPIs) to androgen deprivation therapy (ADT), with or without docetaxel (Doc), is currently recommended for metastatic, hormone-sensitive prostate cancer (mHSPC). Recently, the ARANOTE trial evaluated the efficacy and safety of Darolutamide + ADT in this setting. We aimed to update a network meta-analysis (NMA) of these combination therapies.Methods: We conducted a systematic search for RCTs on systemic therapies for mHSPC using MEDLINE, Embase, and the Web of Science Core Collection in September 2024. An NMA utilizing random-effects models was performed to compare progression-free survival (PFS), overall survival (OS), and adverse event (AE) incidence (PROSPERO: CRD42024591458).Results: A total of 12 RCTs (n = 11,954) were included in our NMAs. Triplet therapies were associated with significant improvements in PFS compared to ARPI-based doublet therapies (hazard ratio [HR]: 0.74; 95% confidence interval [CI]: 0.59–0.93;p= 0.01), but the difference did not reach the conventional levels of statistical significance for OS (HR: 0.82; 95% CI: 0.67–1.01;p= 0.059). In a subset analysis, compared to ARPI-based doublet therapies, triplet therapies showed a significant improvement in PFS in patients with high-volume disease (HR: 0.64; 95% CI: 0.47–0.88;p< 0.01), whereas no significant improvement was observed in those with low-volume disease (HR: 0.86; 95% CI: 0.45–1.67;p= 0.7). No significant difference in grade ≥ 3 AEs was observed between triplet therapies and ARPI-based doublet therapies. The main limitations include patient heterogeneity and limited follow-up in some studies.Conclusions: Triplet therapies can improve the oncologic outcomes of patients with mHSPC compared to ARPI-based doublet therapies, without significantly increasing severe AEs. These findings warrant further confirmation in a head-to-head trial powered for overall survival.
目的:目前推荐在雄激素剥夺疗法(ADT)基础上联合雄激素受体通路抑制剂(ARPI),无论是否加用多西他赛(Doc),用于治疗转移性激素敏感性前列腺癌(mHSPC)。近期,ARANOTE试验评估了达罗他胺联合ADT在该背景下的疗效与安全性。本研究旨在更新关于这些联合疗法的网络荟萃分析(NMA)。 方法:我们于2024年9月系统检索了MEDLINE、Embase和Web of Science核心合集数据库中关于mHSPC全身治疗的随机对照试验。采用随机效应模型进行NMA,以比较无进展生存期(PFS)、总生存期(OS)和不良事件(AE)发生率(PROSPERO注册号:CRD42024591458)。 结果:我们的NMA共纳入12项随机对照试验(n = 11,954)。与基于ARPI的双联疗法相比,三联疗法与PFS的显著改善相关(风险比[HR]:0.74;95%置信区间[CI]:0.59–0.93;p = 0.01),但在OS方面的差异未达到传统统计学显著性水平(HR:0.82;95% CI:0.67–1.01;p = 0.059)。在亚组分析中,与基于ARPI的双联疗法相比,三联疗法在高瘤负荷患者中显示出PFS的显著改善(HR:0.64;95% CI:0.47–0.88;p < 0.01),而在低瘤负荷患者中未观察到显著改善(HR:0.86;95% CI:0.45–1.67;p = 0.7)。三联疗法与基于ARPI的双联疗法在≥3级AE发生率方面未观察到显著差异。主要局限性包括患者异质性以及部分研究的随访时间有限。 结论:与基于ARPI的双联疗法相比,三联疗法可改善mHSPC患者的肿瘤学结局,且未显著增加严重AE。这些发现有待在以后以总生存期为终点的头对头试验中进一步验证。
