Clear cell renal cell carcinoma (CCRCC) is an aggressive form of cancer and a paradigmatic example of intratumor heterogeneity (ITH). The hawk-dove game is a mathematical tool designed to analyze competition in biological systems. Using this game, the study reported here analyzes the early phase of CCRCC development, comparing clonal fitness in homogeneous (linear evolutionary) and highly heterogeneous (branching evolutionary) models. Fitness in the analysis is a measure of tumor aggressiveness. The results show that the fittest clone in a heterogeneous environment is fitter than the clone in a homogeneous context in the early phases of tumor evolution. Early and late periods of tumor evolution in CCRCC are also compared. The study shows the convergence of mathematical, histological, and genomics studies with respect to clonal aggressiveness in different periods of the natural history of CCRCC. Such convergence highlights the importance of multidisciplinary approaches for obtaining a better understanding of the intricacies of cancer.
透明细胞肾细胞癌是一种侵袭性癌症,也是肿瘤内异质性的典型范例。鹰鸽博弈是一种用于分析生物系统竞争关系的数学工具。本研究运用该博弈理论,通过比较同质性(线性进化)与高度异质性(分支进化)模型中的克隆适应度,分析了透明细胞肾细胞癌的早期发展阶段。本分析中的适应度是衡量肿瘤侵袭性的指标。研究结果显示,在肿瘤进化早期阶段,异质环境中最具适应性的克隆比同质环境中的克隆具有更强的适应性。研究还比较了透明细胞肾细胞癌早期与晚期的肿瘤进化过程。该研究展示了数学、组织学和基因组学在透明细胞肾细胞癌自然史不同时期克隆侵袭性研究中的交叉验证。这种多学科研究的趋同性凸显了采用跨学科方法对于深入理解癌症复杂机制的重要性。
