San Francisco—Two proteins linked to tumor invasion and metastasis can help identify women with breast cancer whose risk of recurrence is low enough that they may want to consider forgoing chemotherapy, according to new research presented here at the American Society of Clinical Oncology (ASCO) annual meeting.

The researchers say that these findings, along with new data from a prospective clinical trial, are convincing enough to recommend routine testing for the two proteins to help determine treatment strategy, particularly for breast cancer patients whose axillary lymph nodes show no sign of cancer cells.
