New Study Shows Doxorubicin Plus Paclitaxel Followed by Weekly Paclitaxel as Adjuvant Therapy for High Risk Breast Cancer Warranted in Place of Doxorubicin Plus Cyclophosphamide Followed by Paclitaxel

22 US Oncology Affiliated Physicians Participate in ASCO Proceedings

HOUSTON, June 4 (HSMN NewsFeed) -- A leading cancer researcher affiliated with the US Oncology Research Network presented findings from a randomized, multicenter phase III trial that compared the disease-free survival (DFS) obtained with two regimens of adjuvant therapy for patients with high-risk breast cancer.


The study results were given in an oral presentation by Dr. David Loesch of Central Indiana Cancer Centers, at the 43rd Annual Meeting of the American Society of Clinical Oncology (ASCO) held June 2-5, 2007 in Chicago. Dr. Loesch is the lead investigator and a member of US Oncology's breast cancer research committee.

The study, titled "A randomized, multicenter phase III trial comparing doxorubicin plus cyclophosphamide followed by paclitaxel or doxorubicin plus paclitaxel followed by weekly paclitaxel as adjuvant therapy for high risk breast cancer" (abstract number 517) was conducted among women with local, operable, confirmed stage I-III adenocarcinoma, who had primary surgery, with no residual tumor.

The research found that Therapy Arm 2 (AT-->T) (doxorubicin 50 mg/m2 plus paclitaxel 200 mg/m2 repeated every three weeks for four cycles-->paclitaxel 80 mg/m2 weekly x12) AT+WP can be considered equal to AC-->T as a standard treatment in the community. It has more peripheral neuropathy than AC-->T; but the neuropathy is reversible. In a repeat analysis of the triple negative subgroup, AP-->WP was superior to AC-->T in overall survival (OS).

In addition, 22 physicians and researchers affiliated with US Oncology participated in oral and poster presentations, moderated panels and published studies at this year's ASCO conference in Chicago. The researchers presented findings on a variety of disease states including lung, gastrointestinal, genitourinary, gynecologic, breast and melanoma.
