Screening of cancer patients for predisposing germline alterations may yield valuable decision support for risk-reducing interventions and surveillance. The presence of specific pathogenic germline variants (e.g. in BRCA1/2) can also have strong implications when it comes to drug response. However, the growing amount of knowledge regarding cancer-predisposing genes and their potential impact on prognosis and treatment is dispersed across multiple databases and online resources. Interpretation of raw variant sets from genetic testing of cancer patients can thus be a significant challenge. The Cancer Predisposition Sequencing Reporter (CPSR) was developed to meet this need. CPSR integrates data from a number of gene and variant databases, and produces interactive and clinically oriented sequencing reports for each cancer case. The tool is open-source and publicly available through its GitHub page.
“The implementation of cancer precision medicine requires a careful understanding of both acquired tumor variants and inherited variants in each cancer patient. CPSR constitutes in this regard a highly valuable complement to our other decision-support tool for somatic aberrations, the Personal Cancer Genome Reporter (PCGR)”, says Sigve Nakken, researcher at Oslo University Hospital, and lead author of the paper.
