LOS ANGELES-Surgical margin width offers a reasonable prognostic surrogate for the more complicated multiparameter Van Nuys Prognostic Index to predict breast cancer recurrence after treatment for ductal carcinoma in situ (DCIS), but the index still provides superior accuracy, Melvin J.

EDMONTON, Canada-In what Jean-Marc Nabholtz, MD, calls “the first trials challenging tamoxifen as the primary drug of choice in postmenopausal women with advanced breast cancer,” anastrozole (Arimidex, a nonsteroidal aromatase inhibitor) proved as effective as tamoxifen (Nolvadex). Dr. Nabholtz, of the University of Alberta, Edmonton, Canada, reported the results at the San Antonio Breast Cancer Symposium.

GREENVILLE, NC-Patient age and surgeon experience appear to play the biggest role in failure of sentinel lymph node biopsy for detection of breast cancer, according to a large multicenter clinical trial presented at the San Antonio Symposium.

ROCHESTER, Minn-Preliminary results from an ongoing Mayo Clinic study show that fluoxetine (Prozac) reduced the incidence of hot flashes in breast cancer survivors by more than 50%, Charles L. Loprinzi, MD, said at the San Antonio Breast Cancer Symposium.

NEW YORK-In patients with ductal carcinoma in situ (DCIS), the identification of positive sentinel lymph nodes (SLNs) is unlikely to be clinically significant, David Brenin, MD, of Columbia-Presbyterian Medical Center, said at the San Antonio Breast Cancer Symposium.

SAN ANTONIO-Treatment with FEC (fluorouracil, epirubicine, cyclophosphamide) to a dose optimized for each patient produced an overall response rate of 82% in a group of 39 Swedish patients with metastatic breast cancer, Dr. H. Lindman and colleagues, of Uppsala University and the Karolinska Institute, reported at the 22nd Annual San Antonio Breast Cancer Symposium.

A substance extracted from licorice root, Licochalcone-A, has been shown to have antitumor activity in acute leukemia, breast, and prostate cancer cell lines by lowering the amount of bcl-2, a drug-resistant protein. Excess amounts of this

The first oral aromatase inactivator for the treatment of postmenopausal women with advanced breast cancer whose tumors have stopped responding to tamoxifen (Nolvadex) therapy is now available in the United States. Pharmacia & Upjohn

Outpatient bone marrow transplant (BMT) strategies, as reviewed by Dix and Geller, have evolved for various reasons—from social to medical. If high-dose approaches are to become a viable treatment for common cancers, such as breast cancer, the refinement of transplants to a “kinder and gentler” approach is essential.

SAN ANTONIO-Estrogen suppression using goserelin (Zoladex) increased the relapse-free interval in premenopausal women with early stage breast cancer, compared with no goserelin, according to an interim analysis of the ZIPP (Zoladex in Premenopausal Patients) trial. Michael Baum, MD, of the Cancer Research Campaign, London, presented the results at the San Antonio Breast Cancer Symposium.

WASHINGTON-An Institute of Medicine (IOM) committee has launched an assessment of technologies for the early detection of breast cancer that will include an examination of the policies and economic factors that delay or prevent their adoption. The year-long effort is part of a 5-year project undertaken by the IOM, an arm of the National Academy of Sciences.

NEW YORK-Studies leading up to FDA approval last year of a new aromatase inactivator, exemestane tablets (Aromasin, Pharmacia & Upjohn), were reviewed at the Chemotherapy Foundation Symposium XVII.

CHICAGO-A new ultrasound technology that amasses as much as nine times more information than conventional ultrasound provides greater detail in characterizing breast lesions and also allows real-time tracking of the entire path of the breast biopsy needle, Jacques Souquet, PhD, senior vice president and chief technology officer at ATL Ultrasound (Bothell, Washington), said in an interview with ONI.

Patients with one of the most common and curable forms of breast cancer may be undergoing radiation therapy unnecessarily, according to a University of Southern California (USC) study published in the May 13, 1999, issue of The New England Journal of Medicine.

Lee Breast Center at the USC/Norris Comprehensive Cancer Center, examined ductal carcinoma in situ (DCIS).

Newman, MD, assistant professor of surgery at M.D. Anderson’s Nellie B. Connally Breast Center, said at a Komen Foundation press briefing on clinical trials. The explanation for these variations is unclear at this point, she said.

BUFFALO, NY-Breast cancer offers a paradigm for cancer prevention issues. It has been shown that lower exposure to estrogen results in a lower risk of breast cancer. However, a decrease in overall estrogen may pose health risks for women such as increased risk for heart disease. Thus, patients and physicians must evaluate all options available, said Richard M. Elledge, MD, medical director of the Breast Care Center at Baylor College of Medicine-The Methodist Hospital, Houston.

Komen Breast Cancer Foundation are opening this year in Italy, Greece, and Argentina, and one probably will open in Germany next year,”said Susan Braun, president and CEO.
