Abstract
Computer implemented methods and computer systems are provided for estimating cancer cell fractions indicating proportions of cancer cells carrying one or more mutations of interest using one or more nucleic acid samples from a subject. The methods and systems provided herein implement processes that use a variational Bayesian mixture model to cluster initial cancer cell fractions and obtain the one or more final cancer cell fractions, the initial cancer cell fractions accounting for cancer purity and copy numbers. The disclosed methods and systems improve accuracy, validity, and reliability of tests for cancer clonality, and save time, materials, cost, and computer resources required for the tests, which can help design more affective cancer treatments.
