New Study Reports Improved Patient Outcomes for Breast Cancer Patients
Date:2/18/2009

VALENCIA, Calif., Feb. 18 /PRNewswire/ -- A new clinical study published this month in The Breast Journal (Vol. 15, No. 1) reports that high-quality patient outcomes for breast-conserving surgery can be achieved in the community hospital setting. This is one of the few and the most recent studies of its kind and is particularly relevant given that nearly two-thirds of all breast cancer patients in the United States are treated at community centers.

The study tracked 185 cases from 1997-2003 at Henry Mayo Newhall Memorial Hospital, located in the Southern California suburb of Valencia. The patients underwent a lumpectomy typically with a 5mm margin, as opposed to the 1-2mm margin performed in surgeries at most institutions. The study includes five-year follow-up data that shows a local recurrence rate of 2 percent as compared to the national norm of 4-9 percent.

"This study basically suggests a resetting of the bar on how to do lumpectomies and what patients can expect if it is done this way," said Henry Mayo's Breast Center Medical Director Gregory Senofsky, M.D. "Our findings are hard to ignore."

According to Barbara Florentine, M.D., medical director of the department of pathology at Henry Mayo and lead author of the study, the first objective of the study was to evaluate the factors known to influence outcomes. "These include tumor and patient characteristics, completeness of local surgical tumor excision, and adjuvant radiation therapy and/or chemotherapy/hormonal treatment," she says. "The second objective was to evaluate the percentage of cases in which the initial breast-conserving surgery did not achieve adequate surgical oncological results (5mm margins) and the number and type of subsequent surgeries that were required to achieve this goal."

Of the 185 cases tracked in this study, 87 percent had successful breast-conserving surgery. A single surgery was deemed sufficient to a
