The national investment that was made in oncology research with the passage of the National Cancer Act in 1971 is now coming to fruition. Nowhere is this more apparent than in the exciting prospects for genetically informed precision medicine as applied to the treatment of children with cancer. The wealth of information gleaned from intensive genetic analyses and NexGen sequencing studies has identified a number of viable targets in leukemias and solid tumors. Our rapidly evolving understanding of the enzymatic controls that regulate chromatin dynamics during normal differentiation of stem cells and their mutation or dysregulation in tumor cells is leading to a new library of therapeutically tractable tumor targets. The recent identification of germline variants associated with toxicity and/or response to therapy has further enhanced our ability to deliver individualized treatments for pediatric cancer patients. Our challenge today is to determine how best to use genomic data and integrate it into evolving clinical protocols to provide more efficacious therapies and a better quality of life for children with cancer.
1971 年《国家癌症法案》通过后,国家在肿瘤学研究上的投入现在开始取得成果。在将遗传信息应用于儿童癌症治疗的精准医学这一令人兴奋的前景上,这一点表现得最为明显。从密集的基因分析和下一代测序研究中收集到的大量信息,已经确定了白血病和实体瘤中一些可行的治疗靶点。我们对调控干细胞正常分化过程中染色质动态的酶控制的理解迅速发展,以及这些酶在肿瘤细胞中的突变或失调,正在导致一系列具有治疗潜力的肿瘤靶标。最近发现与毒性和/或对治疗反应相关的种系变异,进一步增强了我们为儿科癌症患者提供个体化治疗的能力。我们今天的挑战是确定如何最好地利用基因组数据,并将其整合到不断发展的临床方案中,为癌症患儿提供更有效的治疗方法和更高的生活质量。
