For years, treatment decisions in breast cancer have largely depended on genetic changes identified in tumor tissue, typically obtained through invasive biopsies. Though, the limitations of tissue sampling and the dynamic nature of cancer have presented notable challenges. Circulating tumor DNA (ctDNA), released into the bloodstream by tumor cells, offers a promising option.

This innovative analysis allows for continuous monitoring and comprehensive genetic profiling, offering clinicians new opportunities to track cancer’s evolution and response to treatment without the need for repeated invasive procedures. The recent study delves into the clinical implications of ctDNA analysis in patients with advanced or metastatic breast cancer, evaluating the prevalence of genetic mutations, factors influencing ctDNA testing, and its impact on clinical decision-making.

Key Findings of the Study

The study involved 49 patients with advanced or metastatic breast cancer who underwent ctDNA analysis using the Guardant360 CDX test, which is approved by the American Food and Medicine Management (FDA). The results revealed that a striking 76% of patients had at least one somatic mutation. The most frequently altered genes were TP53 (29%), PIK3CA (24%), FGFR1 (20%), and ATM (16%).

Further analysis revealed mutations in BRCA1 and BRCA2 in 6% and 8% of patients, respectively, while 12% of patients exhibited ESR1 mutations. Thes findings underscore the potential of ctDNA as a valuable biomarker, particularly for patients with hormone receptor-positive and HER2-negative breast cancer.

The study also demonstrated that ctDNA testing influenced treatment decisions in 35% of cases, making patients eligible for therapies such as Alpelisib, Elacestrant, and Capivitsertib. The high level of agreement between ctDNA results and those obtained from FFPE tissue samples further reinforces the reliability of this non-invasive testing method.
