Abstract Oncogene amplification and tumor suppressor deletion can drive tumor initiation, progression and treatment resistance. Detection at diagnosis often signals poor prognosis, but it can also enable opportunities for treatment with highly effective targeted therapies. Predicting the likelihood that a patient will acquire these driver alterations in the future using a genomic test represents an opportunity to realize the benefits of interventions earlier, potentially with preventative intent. Here, we present a forecasting framework that takes as input a DNA copy number profile and predicts whether the tumor will acquire an oncogene amplification or tumor suppressor deletion in the future. This framework leverages mutation rate estimates from the input tumor, alongside gene-specific selection coefficients derived from a large cohort of 7,880 tumors. We demonstrate feasibility using 7,042 single-time-point samples and longitudinally collected tumor pairs from 44 prostate and 100 lung cancers, identifying tumors that went on to acquire amplifications at a later time point with an average AUC of 0.87. We show potential clinical utility by forecasting poor prognosis in low-grade gliomas via CDK4/PDGFRA amplification or CDKN2A deletion, and osimertinib resistance in lung cancers via MET amplification. This study serves as a proof-of-concept for a new class of biomarker, wherein selective pressures and mutation-generating processes can be harnessed to anticipate future genomic alterations.

Hernando et al. (Fri,) conducted a observational in Cancer (Prostate, Lung, Glioma) (n=15,066). Forecasting framework using DNA copy number profile was evaluated on Prediction of future oncogene amplification or tumor suppressor deletion (AUC 0.87). A forecasting framework using DNA copy number profiles predicted future oncogene amplifications and tumor suppressor deletions with an average AUC of 0.87.
