Selected Research

Efficacy of imatinib in aggressive fibromatosis

Aggressive fibromatoses are rare clonal neoplastic proliferations that can be aggressive despite surgery and/or radiation therapy. In this article, published in Clinical Cancer Research (2010;16:4884-4891), Dr. Priebat and colleagues report the outcomes of patients treated with imatinib in phase 2 of the Sarcoma Alliance for Research through Collaboration (SARC) Trial.

Monitoring of cardiac toxicity caused by doxorubicin

Doxorubicin is commonly used to treat solid tumors, such as breast, sarcoma, gynecologic and hematological malignancies. However, use of this drug is limited because of its effects on the heart. In this article, published in Clinical Nuclear Medicine (2009;34:762-767), Dr. Priebat and colleagues present an overview on the use of gated cardiac blood pool studies to assess the cardiac effects of doxorubicin.
