The negative effect of triple-negative breast cancer on outcome after breast-conserving therapy.

Purpose: To evaluate disease failure patterns and overall survival (OS) of women with triple-negative (TN) breast cancer who underwent breast-conserving therapy (BCT) and to understand the relationship of TN tumors with other prognostic factors.

Patients And Methods: The Surveillance, Epidemiology, and End Results (SEER) registry identified 562 women diagnosed and/or treated with unilateral invasive breast cancer during 2003-2004 at three Emory hospitals. After medical record review, 193 eligible women, with all tumor types, received BCT.

Unraveling the Mystery of Erythropoietin-Stimulating Agents in Cancer Promotion.

Erythropoietin-stimulating agents (ESA) are approved for use in treating chemotherapy-induced anemia in patients with nonmyeloid malignancies. However, recent clinical trials have shown evidence of inferior overall survival and/or locoregional control of tumors in patients receiving ESAs. Given these concerning data, current studies are focused on elucidating the biological mechanisms by which ESAs may contribute to cancer promotion.
