在刚刚落幕的第61届美国临床肿瘤学会(ASCO)年会上,全球肿瘤治疗领域再次迎来振奋人心的消息。多项针对乳腺癌、肺癌和血液肿瘤的最新临床研究数据重磅发布,这些突破性进展不仅为患者带来了新的治疗选择,更彰显了医学界在抗击癌症道路上的坚定承诺。
乳腺癌治疗新突破:伊那利塞显著延长PIK3CA突变患者生存期
对于内分泌耐药、PIK3CA突变且HR+/HER2-的局部晚期或转移性乳腺癌患者而言,一线治疗方案的突破至关重要。III期INAVO120研究的最新数据显示,伊那利塞(inavolisib)联合哌柏西利(palbociclib)和氟维司群(fulvestrant)的治疗组合,将患者的中位总生存期(OS)延长至34个月,相较于安慰剂联合对照组的27个月,显著延长了7个月。这意味着携带PIK3CA突变的HR阳性、HER2阴性晚期乳腺癌患者的死亡风险降低了30%以上。
PIK3CA突变在HR阳性晚期乳腺癌中普遍存在,约占40%,且常预示着不良预后。除了INAVO120研究,伊那利塞(Itovebi™)目前还在多项III期临床试验(INAVO121, INAVO122, INAVO123)中进行评估,旨在探索其在不同联合治疗方案下,为更多PIK3CA突变乳腺癌患者带来靶向治疗的益处。这些研究的积极进展,为乳腺癌患者带来了新的希望,也为乳腺癌靶向药的研发指明了方向。
广泛期小细胞肺癌:阿替利珠单抗联合鲁比替康带来生存获益
小细胞肺癌(SCLC)是一种侵袭性极强、预后较差的肺癌类型,尤其是广泛期小细胞肺癌(ES-SCLC),治疗选择相对有限。III期IMforte研究的积极结果显示,阿替利珠单抗(Tecentriq)联合鲁比替康(Lurbinectedin)作为广泛期小细胞肺癌一线维持治疗方案,取得了显著的生存获益。该方案将疾病进展或死亡风险降低了46%,死亡风险降低了27%。
这是首个在广泛期小细胞肺癌一线维持治疗中,同时证实无进展生存期(PFS)和总生存期(OS)均取得临床意义改善的III期研究。这一突破性发现,为ES-SCLC患者提供了急需的有效治疗选择,也为肺癌治疗领域注入了新的活力。对于寻求抗癌药代购或了解仿制药信息的患者,关注此类最新临床研究进展至关重要。
复发或难治性淋巴瘤:格罗菲妥单抗方案展现巨大潜力
弥漫性大B细胞淋巴瘤(DLBCL)是一种侵袭性淋巴瘤,对于不适合移植的复发或难治性(R/R DLBCL)患者,有效的治疗方案尤为紧迫。III期STARGLO研究的两年随访更新数据证实,格罗菲妥单抗(Glofitamab)联合吉西他滨(Gemcitabine)和奥沙利铂(Oxaliplatin)的Glofit-GemOx方案,可显著延长患者的总生存期。目前中位OS尚未达到,疾病死亡风险降低了40%。
更令人鼓舞的是,在Glofit-GemOx方案治疗结束时获得完全缓解的患者中,82%未发生疾病进展,且完全缓解率高达58.5%,患者可持续获得完全缓解状态。作为一种亟需的、固定疗程、“即用型”TCE疗法,Glofit-GemOx方案在治疗侵袭性、危及生命的复发或初始治疗失败的DLBCL方面展现出巨大潜力,为淋巴瘤新药的研发和应用带来了新的曙光。
