Blood Test Could Predict When Melanomas Will Come Back

A new blood test could show whether melanomas are likely to return in patients who are clinically free of the disease, according to a study in the Journal of Clinical Oncology. Cancer cells that break off tumors can enter blood vessels; this test identifies three tumor cell biomarkers in blood. The researchers periodically tested blood samples of 322 patients and found those with up to one cancer biomarker were more likely to be melanoma-free compared to those with two or more cancer biomarkers (73% vs 59%). This test could show which patients would benefit from aggressive treatments.
