Diagnostic tool Oncotype DX associated with reduction in chemotherapy rates post-surgery in younger women with breast cancer — ScienceDaily

Mariana Chavez Mac Gregor, M.D., assistant professor, health services research and breast medical oncology, will present the findings at a poster session of the 2014 San Antonio Breast Cancer Symposium. Oncotype DX is a 21-gene assay used to help estimate the likelihood of recurrence in women with early-stage breast cancer and, thus, determine those who may or may not benefit from adjuvant chemotherapy. The National Comprehensive Cancer Network includes its use for women with lymph node-negative, hormone receptor (HR)-positive and HER2-negative disease. …

Deep sequencing of breast cancer tumors predict outcomes after single dose of therapy

Results showed that through deep genome sequencing, a reduction in the most commonly mutated genes in breast cancer could be observed after just one dose of preoperative therapy. Deep sequencing is a process that involves sequencing the same region multiple times to identify mutations within tumors that have an importance in cancer evolution. These new findings were presented during the 2013 San Antonio Breast Cancer Symposium. "Genomics is the new frontier of cancer research, and this study shows that we may be able to accurately determine what treatment methods will and will not be effective for individual patients after just one dose of medicine," said Lyndsay Harris, MD, study investigator and Director, Breast Cancer Program, UH Seidman Cancer Center and Professor of Medicine at Case Western Reserve University School of Medicine. …
