Abstract
Implications for Practice Circulating tumor cells (CTC)-based risk stratification may have a role for future treatment strategies, as it enables the selection of subgroups with differential response potential. Machine learning [...]
Despite the strong prognostic stratification of circulating tumor cells (CTCs) enumeration in metastatic breast cancer (MBC), current clinical trials usually do not include a baseline CTCs in their design. This study aimed to generate a classifier for CTCs prognostic simulation in existing datasets for hypothesis generation in patients with MBC. A K-nearest neighbor machine learning algorithm was trained on a pooled dataset comprising 2436 individual MBC patients from the European Pooled Analysis Consortium and the MD Anderson Cancer Center to identify patients likely to have CTCs [greater than or equal to] 5/7 mL blood ([StageI.sup.Vaggressive] vs [StageIV.sup.indolent]). The model had a 65.1% accuracy and its prognostic impact resulted in a hazard ratio (HR) of 1.89 ([Simulated.sup.aggressive] vs [Simulated.sup.indolent] P Key words: clinical trial model; machine learning; liquid biopsy; biomarker; K-nearest neighbor.
