在过去的30年里,肺癌患者的生存率几乎没有提高。需要新的癌症反应评估基准,以具有成本效益和及时的方式测试治疗药物。从最近的工作中,很明显,原发性肺癌是非常复杂的结构,不仅含有癌细胞,而且还含有纤维化和炎症细胞以及坏死组织。对原发性肺癌的三维结构的更深入了解正在出现,这是第一次对这种生物量在医学成像数据中的表现方式进行评估。只有通过更好地了解肺癌生物量,我们才能定义合理的早期反应措施,包括特定的细胞反应,如癌细胞死亡或生长抑制。在这样做的过程中,我们可以定义响应指标,这将缩短新药发现时间并降低成本,从而可以评估更多具有治疗潜力的药物。
The survival rate for lung cancer patients has barely improved over the past 30 years. New evaluation benchmarks for cancer response are needed to test therapy agents in a cost-effective and timely manner. From recent work, it is evident that primary lung cancers are very complex structures containing not only cancerous cells but also fibrotic and inflammatory cells and necrotic tissue. A greater understanding of the three-dimensional structure of primary lung cancer is emerging, allowing for the first time an appreciation of how this biomass is represented in medical imaging data. It is only through a greater understanding of the lung cancer biomass that we can define rational and early-response measures, including specific cellular responses such as cancer cell death or growth inhibition. In doing so, we can define response metrics that will shorten new drug discovery times and reduce costs, allowing for the evaluation of many more agents with therapeutic potential.
