A simple blood test that detects tumor cells circulating in the blood shows promise as a new way to predict high or low risk of a breast cancer relapse. This is according to data presented today at the 40th annual San Antonio Breast Cancer Symposium. A proof-of-concept study by the ECOG-ACRIN Cancer Research Group (ECOG-ACRIN) measured the prevalence of circulating tumor cells (CTCs) in blood samples from patients cancer-free five years or more after diagnosis, then associated CTC presence with a later recurrence. "Late recurrence five or more years after surgery accounts for at least one-half of recurrences of breast cancer, and there are no tests that identify who is at highest risk. We found that in women who were cancer-free five years after diagnosis, about 5 percent had a positive CTC test," said lead researcher Joseph A. Sparano, MD, vice chair of the ECOG-ACRIN Cancer Research Group, Philadelphia, and associate director for clinical research at Montefiore Medical Center, Albert
