精确医学的一个目标是识别单个肿瘤中的突变,以设计有针对性的治疗方法。这份报告详细介绍了使用基因组测试来选择埃洛替尼和雷帕霉素的靶向治疗方案,以治疗对标准治疗无效的儿童间变性少突胶质细胞瘤,实现了33个月的持续有效。对总蛋白和磷酸化蛋白异构体的免疫组织化学分析显示,异常信号与检测到的突变一致,同时揭示了在整个病程中多个肿瘤细胞亚群中每个细胞激活信号通路的异质性。这个案例突出了可能与设计未来靶向治疗相关的分子特征。
One goal of precision medicine is to identify mutations within individual tumors to design targeted treatment approaches. This report details the use of genomic testing to select a targeted therapy regimen of erlotinib and rapamycin for a pediatric anaplastic oligodendroglioma refractory to standard treatment, achieving a 33-month sustained response. Immunohistochemical analysis of total and phosphorylated protein isoforms showed abnormal signaling consistent with detected mutations, while revealing heterogeneity in per-cell activation of signaling pathways in multiple subpopulations of tumor cells throughout the course of disease. This case highlights molecular features that may be relevant to designing future targeted treatments.
