ASCO 2021: 肝细胞癌重磅研究研究(第一期)

1,中国肝细胞癌(HCC)患者辅助治疗决策的影响因素

本研究旨在了解中国肝细胞癌(HCC)切除术后辅助治疗的患者决策因素。

该研究使用调查问卷(https://pro.wenjuan.com/t/jUZFU)对过去2年在中国27家医院接受HCC手术切除的患者进行了调查。问卷结果通过电话或网络收集反馈。

该问卷调查涵盖三个方面:辅助治疗的决策、治疗方案的选择和复发风险对接受辅助治疗意愿的影响,并对其从1(无影响)到7(高影响)进行评分。平均得分为67分的因素被认为是有影响的,分数≤5分的因素被认为不会产生影响。本研究得到了中山医院伦理委员会的批准,患者提供了知情同意书。

结果显示,总共收集了2220份有效答卷,2183名患者来自中山医院,37名来自其他26家医院,75%的受访者为男性,50-70岁的患者占比为60%50%患者家庭月收入≤5000元人民币(约740美元)。在受访者中,62%接受过辅助治疗,56%接受了系统治疗(化疗、酪氨酸激酶抑制剂、免疫治疗和中药),27%接受了经动脉化疗栓塞(TACE)加系统治疗,17%单独接受了TACE治疗。

大多数受访者(75%)认为医生是使用辅助治疗和选择治疗方案的决策者。在没有接受辅助治疗的38%的受访者中,90%的受访者表示医生建议不给予辅助治疗。当患者是决策者时,影响使用辅助治疗和选择治疗方案的因素从影响最多到最少排列依次为:疗效(预防肿瘤复发)、报销情况、治疗副作用和费用成本。患者接受辅助治疗的意愿受到预测复发风险的影响,在估计2年复发风险>10%>30%的受访者中,分别有40%56%的人认为他们应该接受辅助治疗。

因此,大多数患者接受了辅助治疗,其中最常见的是全身治疗和TACE接受切除术的患者强烈希望通过辅助治疗减少术后复发。医生意见被认为是治疗决策中最重要的因素,其次是经济因素。当患者是决策者时,最具影响力的因素是治疗效果,其次是报销情况。

2,什么时候是最佳时机?lenvatinib联合 TACE 治疗不可切除的肝细胞癌:中国真实世界证据的回顾性分析

TACElenvatinib被证明可以延长不可切除的HCC患者的总生存期,两者的联合同样可改善临床疗效,并在真实世界中得到了广泛使用。然而,在TACE基础上加用lenvatinb的最佳时机仍不清楚。该研究旨在评估两种联合策略治疗不可切除的肝细胞癌的疗效和安全性。

研究人员收纳了来自201811月到20206月,79名患者接受了TACElenvatinib联合治疗,随访超过2个月,并被分为早期联合治疗组(在第一次TACE之前或后加用lenvatinib)和晚期联合治疗组(在至少两次TACE手术后加用lenvatinib)。根据RECIST1.1标准评估肿瘤反应和无进展生存期(PFS,从使用lenvatinib的第一天到病情进展或死亡的时间),在基线和每2个月后进行肝功能评估。

结果显示,最终共收纳48名不可切除 HCC患者,所有患者的中位随访时间为9.35.3-14.3)个月。两组患者的基线特征相似。早期联合组(n=22)和晚期联合组(n=26)的平均年龄分别为65±9.7岁和61±11.6岁;BCLC CHCC59%54%p=0.89);Child-Pugh A比例为81.8%77%p=0.73)。客观缓解率(ORR)(18.2% vs 26.9%P=0.51)和疾病控制率(90.9% vs 92.3%P=1.00)没有显著差异。早期联合治疗组的中位PFS明显长于晚期联合治疗组(14.5个月 vs 8.9个月;P=0.048)。两组的安全状况相似。3/4级不良事件分别为3例(13.6%)和2例(7.7%)(P=0.65)。

因此,该研究是迄今为止首个关于lenvatinibTACE联合治疗不可切除HCC患者时机的真实世界数据。对于具有较长mPFS的患者来说,早期联合治疗策略可能是一个更好的选择。

3OPTIMIS研究:肝细胞癌经动脉化疗栓塞 (TACE) 后肝功能恶化情况

TACE通常用于不可切除的HCC患者,适当的选择可获得最佳疗效。然而,对于TACE的不适合性和难治性,目前还没有全球公认的共识。先前回顾性研究表明,在难治性或失败后继续进行TACE是有害的,并可能导致患者因肝功能恶化而不符合进一步治疗的要求。在该OPTIMIS探索分析中,评估了首次TACE后的基线肝脏特征评估了肝功能恶化的发生率。

OPTIMIS研究中,共招募了1670HCC患者,最终共有977名患者接受TACE治疗。肝功能恶化被定义为与基线相比,CTCAE 分级恶化,这些参数包括天冬氨酸氨基转移酶(AST)、丙氨酸氨基转移酶(ALT)、总胆红素、白蛋白和凝血酶标准化比率(INR)。

结果显示,BCLC C期与B期的患者中,肝脏恶化的发生率更高。超过7级标准的患者与7级以内的患者肝脏恶化的发生率分别为49% vs 43%。在基线时,不适合做TACE的患者与被符合条件的患者肝脏恶化的发生率分别为53% vs 44%

在真实世界的环境中,HCC患者在TACE后观察到肝功能参数的恶化。因此,适当地选择TACE和保护肝功能对于优化TACE和后续治疗的益处非常重要。
