🚨⭐ #ESMO26 | GU 肿瘤学——第 1 日重点
@urologysummit
GU 肿瘤学的精彩开幕日——涵盖围手术期免疫治疗、ctDNA、靶向治疗及下一代疗法。
对我来说,最核心的信息是?
更多治疗并不自动意味着更好的治疗。
🟠 1️⃣ KEYNOTE-866 | 4735O
围手术期 pembrolizumab + gemcitabine/cisplatin 未在适合使用 cisplatin 的 MIBC 患者中显著改善 EFS。
📊 EFS HR 0.88 (95% CI 0.71–1.10), p=0.1366
pCR:44.4% vs 35.8%
💡 更高的病理学缓解率并未转化为显著的 EFS 获益。
🟠 2️⃣ ENERGIZE | 4736O
围手术期 nivolumab + 化疗同样未达到共同主要终点。
📊 EFS HR 0.94, p=0.6697
pCR:39.1% vs 29.6%
这再次提醒我们,缓解终点必须结合持久性结局来解读。
🟠 3️⃣ KEYNOTE-905 / KEYNOTE-B15 | 4733O / 4734O
在 KEYNOTE-905 的探索性分析中,EV + pembrolizumab 相较于单纯手术更具优势:
✅ OS HR 0.48
✅ pCR:EV + pembrolizumab 组为 58.8%,pembrolizumab 单独治疗组为 25.3%,单纯手术组为 10.3%
在 KEYNOTE-B15 中:
🧬 ctDNA 清除率:EV+pembro 组为 82.1%,GC 组为 66.7%
ctDNA 阳性与较差的 EFS 相关。
用于风险分层很有前景——但 ctDNA 指导的治疗仍需前瞻性验证。
🟠 4️⃣ TROPHY-U-01 Cohort 7 | 4742O
SG + EV + zimberelimab 用于未经治疗的转移性尿路上皮癌:
✅ ORR 81%
✅ 中位 PFS 19.3 个月
✅ 中位 DoR 16.7 个月
⚠️ 非常有前景,但属于 Ib 期、仅纳入 21 例患者,且毒性明显。
🔵 5️⃣ CAPItello-281 | LBA56
在 PTEN 缺陷型新发 mHSPC 中:
capivasertib + abiraterone 对比安慰剂 + abiraterone
✅ 中位 OS 57.4 vs 46.5 个月
HR 0.82 (95% CI 0.68–0.99)
但未达到预设的显著性阈值。
这是一个令人鼓舞的生存信号——尚不能确认正式的 OS 获益。
🔵 6️⃣ 前列腺癌的下一个前沿领域
☢️ PSMA 靶向放射配体疗法
🧬 AR 降解剂与 RIPTACs
💊 下一代 ADCs
🔬 T 细胞衔接器与精准免疫治疗
当前的挑战是将生物学活性转化为持久获益、可控的毒性以及更精准的患者选择。
⭐ 我的观点
今天最突出的三条原则:
✅ 生存及预防转移的终点至关重要
✅ 生物标志物必须从预后判断价值转向指导治疗
✅ 新型联合治疗必须同时在疗效和毒性方面证明其合理性
GU 肿瘤学的未来并非一味强化治疗,而是进行更智能、以生物学为基础的治疗选择。
🎯 正确的策略。正确的患者。正确的时机。

Perioperative pembrolizumab (pembro) or placebo (pbo) + neoadjuvant cisplatin (cis) and gemcitabine (gem) in participants (pts) with muscle-invasive bladder cancer (MIBC): the double-blind, phase 3 KEYNOTE-866 study
https://esmocongress.esmo.org🚨⭐ #ESMO26 | GU ONCOLOGY — DAY 1 HIGHLIGHTS @OncoAlert 🟠🔵 From perioperative immunotherapy to molecular precision and next-generation treatments. A remarkable opening day in GU oncology, with important lessons for both #BladderCancer and #ProstateCancer. Here are our key scientific takeaways 👇 🟠 1️⃣ KEYNOTE-866 Abstract 4735O ❌ Perioperative pembrolizumab + gemcitabine/cisplatin failed to significantly improve EFS in cisplatin-eligible MIBC. 📊 EFS HR 0.88 (95% CI 0.71–1.10) p=0.1366 pCR: 44.4% vs 35.8% 💡 Higher pathological response did not translate into a statistically significant EFS benefit. 🟠 2️⃣ ENERGIZE Abstract 4736O ❌ Perioperative nivolumab + chemotherapy also failed to meet its co-primary endpoints. 📊 EFS HR 0.94; p=0.6697 pCR: 39.1% vs 29.6% 🔬 These findings reinforce the need to interpret response endpoints alongside durable clinical outcomes. 🟠 3️⃣ KEYNOTE-905 & KEYNOTE-B15 | 4733O / 4734O ✅ The exploratory three-arm KEYNOTE-905 analysis favored EV + pembrolizumab over surgery alone. 📊 OS HR 0.48 pCR: 58.8% vs 25.3% with pembrolizumab alone and 10.3% with surgery alone. 🧬 KEYNOTE-B15: ctDNA clearance with EV + pembrolizumab vs gemcitabine/cisplatin: ✅ 82.1% vs 66.7% ctDNA positivity was associated with poorer EFS. 📌 Molecular monitoring offers exciting opportunities for risk stratification, but ctDNA-guided treatment decisions still require prospective validation. 🟠 4️⃣ TROPHY-U-01 COHORT 7 4742O 💊 SG + EV + zimberelimab in untreated metastatic urothelial cancer. ✅ ORR: 81% ✅ Median PFS: 19.3 months ✅ Median DoR: 16.7 months ⚠️ Phase Ib, only 21 patients, with substantial toxicity. Promising—but not yet practice-changing. 🔵 5️⃣ CAPItello-281 LBA56 Updated overall survival in PTEN-deficient de novo mHSPC. 📊 Capivasertib + abiraterone vs placebo + abiraterone: ✅ Median OS: 57.4 vs 46.5 months HR 0.82 (95% CI 0.68–0.99) ⚠️ The prespecified statistical significance threshold was not met. An encouraging survival signal, but not a formally established OS benefit. 🔵 6️⃣ THE NEXT FRONTIER IN PROSTATE CANCER Today's educational sessions highlighted major advances in: ☢️ PSMA-targeted radioligand therapy 🧬 AR degraders and RIPTACs 💊 Next-generation ADCs 🔬 T-cell engagers and precision immunotherapy The key challenge is moving from promising biological activity toward durable clinical benefit, acceptable toxicity and better patient selection. ⭐ POINT OF VIEW More treatment does not always mean better outcomes. And an impressive response rate does not automatically establish a new standard of care. Today's data reinforce three essential principles: ✅ Robust survival endpoints matter. ✅ Biomarkers must move from prognostic value to validated therapeutic guidance. ✅ Novel combinations require careful assessment of efficacy, toxicity and clinical applicability. 💡 The future of GU oncology is not simply treatment intensification—it is smarter, biologically informed treatment selection. 🎯 The right strategy. The right patient. The right time. Outstanding scientific discussions throughout Day 1! @gbanna74 @ravikanesvaran @nataliagandur @neerajaiims @Sebastiano_Buti @CinziaConted @dralishadamani @amg120395 @PGrivasMDPhD @koshkin85 @MicheleMaffezz @ParamMariappan @dmukherji @VanitaNoronha @montypa @DanieleRaggi83 @PasRescigno @jteoh_hk @alison_tree @DrYukselUrun @yekeduz_emre @AgrawalTrush @ONCOassist @VuMedi @ProstateUK @OncologyNT @OncJournal #GUOncology #BladderCancer #ProstateCancer #mCRPC #MIBC #PrecisionOncology在 X 查看被引用的帖子
