Scientists from the University of California have discovered theoretically targetable mutations in a breast cancer patient , using whole genome sequencing . The researchers were able to isolate and study the 61-year - old patient 's liquid contents at early stages of her treatment , using only five different tumor cells at a time , due to the prohibitive cost of larger batches . The patient is suffering from ER - positive / HER2-negative metastatic breast cancer . The group 's findings were published in the cancer Research journal .
Scientists from the University of California have discovered theoretically targetable mutations in a breast cancer patient, using whole genome sequencing. The team were able to isolate and study the 61-year-old patient's liquid biopsies at two stages of her treatment, using only five circulating tumor cells at a time, due to the prohibitive cost of larger batches. The patient is suffering from ER-positive/HER2-negative metastatic breast cancer. The group's findings were published in the Cancer Research journal.
