Using Machine Learning to Predict TP53 Mutation Status and Aggressiveness of Prostate Cancer from Routine Histology...

Despite years of progress, we still lack reliable tools to predict the aggressiveness of tumors, including in the case of prostate cancer. Biomarkers have been developed, but they often suffer from poor accuracy if used alone due to tumor heterogeneity. Nevertheless, some mutations, notably TP53 mutations, are highly correlated with progression. In their work in this issue of Cancer Research, Pizurica and colleagues implemented a machine learning-based model applied to routine histology and trained with prior information on TP53 mutation status. Their model output provides a quantitative prediction of TP53 mutation status while having a strong correlation with aggressiveness, showing promise as a prognostic in silico biomarker.
