《自然-医学》:精准治疗改善高危儿童肿瘤患者预后生存
研究纳入了前384名连续入组了ZERO儿童癌症精准医疗临床试验的高危肿瘤患儿,其中160名患儿为新发、184名初次复发、40名多次复发,入组时中位年龄为10.9岁(包括14名患有儿童肿瘤的成人),3年的总体生存率为34%(图1a)。根据此前报道过的可干预分子靶点,MTB采用五级来确立建议的证据等级,并且只有在药物存在年龄别药物安全数据、在澳大利亚可以通过注册的适应症、临床试验、同情给药、超药品说明书外使用等途径获得药物的情况下才会推荐PGT。

原文摘要(Abstract)
Recent research showed that precision medicine can identify new treatment strategies for patients with childhood cancers. However, it is unclear which patients will benefit most from precision-guided treatment (PGT). Here we report consecutive data from 384 patients with high-risk pediatric cancer (with an expected cure rate of less than 30%) who had at least 18 months of follow-up on the ZERO Childhood Cancer Precision Medicine Program PRecISion Medicine for Children with Cancer (PRISM) trial. A total of 256 (67%) patients received PGT recommendations and 110 (29%) received a recommended treatment. PGT resulted in a 36% objective response rate and improved 2-year progression-free survival compared with standard of care (26% versus 12%; P = 0.049) or targeted agents not guided by molecular findings (26% versus 5.2%; P = 0.003). PGT based on tier 1 evidence, PGT targeting fusions or commenced before disease progression had the greatest clinical benefit. Our data show that PGT informed by comprehensive molecular profiling significantly improves outcomes for children with high-risk cancers. ClinicalTrials.gov registration: NCT03336931.
