Abstract
Breast cancer is a highly heterogeneous and dynamic disease, exhibiting unique somatic alterations that lead to disease recurrence and resistance. Tumor biopsy and conventional imaging approaches are not able to provide sufficient information regarding the early detection of recurrence and real time monitoring through tracking sensitive or resistance mechanisms to treatment. Circulating tumor DNA (ctDNA) analysis has emerged as an attractive noninvasive methodology to detect cancer-specific genetic aberrations in plasma including DNA mutations and DNA methylation patterns. Numerous studies have reported on the potential of ctDNA analysis in the management of early and advanced stages of breast cancer. Advances in high-throughput technologies, especially next generation sequencing and PCR-based assays, were highly important for the successful application of ctDNA analysis. However, before being integrated into clinical practice, ctDNA analysis needs to be standardized and validated through the performance of multicenter prospective and well-designed clinical studies. This review is focused on the clinical utility of ctDNA analysis, especially at the DNA mutation and methylation level, in breast cancer patients, incorporating the latest advances in technological approaches and involving key studies in the early and metastatic setting. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group
