No significant differences were detected in recurrence free survival between women who received chemotherapy and those who did not among women with triple negative breast cancer (TNBC) or within any other breast cancer subtypes, in a study of 437 women diagnosed with T1a/T1b N0 breast cancer with a median follow-up of 6.2 years. Other details of the study include:
• Chemotherapy was administered more often to younger women, and to women with high grade, HER2+ or TN breast cancers.
• Recurrence free survival did not different significantly between TNBC and ER+ breast cancer (HR, 0.33).
