A recently granted patent (Publication Number: US11929148B2) outlines a method for determining the cancer class of a subject by analyzing cell-free DNA molecules in a biological sample. The process involves extracting these molecules, removing those longer than a specified threshold length, sequencing the sample, identifying relative copy numbers at various genomic locations, and applying this data to a machine learning model trained to determine the cancer class based on genomic information.

The method detailed in the patent covers a range of cancer-related classifications, including the presence of cancer, cancer stage, type, and prognosis. By utilizing a machine learning model trained with labeled data, the approach aims to provide accurate cancer classification based on genomic information obtained from the biological sample. The patent also specifies the use of a specific threshold length for DNA molecules, the number of sequence reads required, and the application of methylation state data in the analysis process. Additionally, the method emphasizes the importance of confidence levels in determining the cancer class, comparing the results obtained through this approach with those from traditional genetic information analysis methods.
