Despite the results of the National Surgical Adjuvant Breast and Bowel Project B-17, there continues to be debate regarding the most appropriate treatment for patients with ductal carcinoma in situ (DCIS) of the breast. Numerous clinical, pathologic, and laboratory factors can aid clinicians and patients wrestling with the difficult
Dr. Fowble's well-written review concludes that, in certain subgroups of patients with breast cancer (ie, patients with primary tumors larger than 5 cm, four or more positive axillary lymph nodes, or tumor involvement of the pectoralis fascia),
CHICAGO-Medical contraindications to breast-preserving cancer surgery occur in a minority of patients with early-stage breast cancer when accepted clinical guidelines are appropriately applied, results from a series of more than 400 patients suggest.
SAN FRANCISCO-A new analysis based on SEER data shows a very low probability of fatal breast cancer among women with DCIS for up to 10 years after diagnosis and treatment. Further, the data suggest that women with DCIS are, overall, healthier than the general population, Virginia L. Ernster, PhD, reported at a poster session of the San Antonio Breast Cancer Symposium.
HEIDELBERG, Germany-Evaluation of bone marrow for breast cancer cells proved superior to axillary lymph node dissection in predicting subsequent metastases in a German study of more than 1,000 patients, Ingo J. Diel, MD, said at a general session of the San Antonio Breast Cancer Symposium.
SAN ANTONIO-Most breast cancer patients vastly overestimate the benefits of adjuvant chemotherapy, believing that it reduces their risk of recurrence by as much as 77%, Laura Siminoff, PhD, reported at a general session of the San Antonio Breast Cancer Symposium.
VIENNA--The fourth-generation aromatase inhibitor letrozole has become the first drug of its class to outperform megestrol acetate as a second-line hormonal therapy for postmenopausal women with metastatic breast cancer who relapsed or progressed during tamoxifen (Nolvadex) therapy.
SAN ANTONIO-Is adjuvant radiotherapy necessary for all breast cancer patients undergoing breast-conserving therapy? Prospective, randomized studies from the NSABP indicate that it is, Norman Wolmark, MD, said in a minisymposium held in conjunction with the San Antonio Breast Cancer meeting.
Within the last 25 years, laboratory research on estrogen receptors and the development of the antiestrogen tamoxifen has dramatically refined and expanded the role of hormonal therapy in the treatment of breast cancer. An assessment of antiestrogens and their role in breast cancer therapy clinical practice was the focus of a roundtable symposium entitled "Antiestrogens: Past, Present, and Future," held in July 1996. The articles compiled in this supplement detail the discussions at the meeting of significant issues related to antiestrogen therapy, including patient selection, duration of treatment, secondary effects, and development of new antiestrogenic compounds.
ATLANTA-A study of more than 400,000 postmenopausal women has found no increased risk of fatal breast cancer with use of estrogen replacement therapy (ERT). In fact, women who reported ever having used estrogen actually had a 16% decreased risk of dying of breast cancer, Dawn Willis, PhD, MPH, reported for the American Cancer Society (ACS) at a general session of the San Antonio Breast Cancer Symposium.
PALM SPRINGS, Calif--Three major randomized trials comparing the antiestrogens toremifene (Fareston) and tamoxifen (Nolvadex) in patients with advanced breast cancer showed no significant differences in efficacy or side effects profiles, Richard Gams, MD, of Ohio State University, said at the symposium.
NEW YORK-Paclitaxel (Taxol) given as a weekly one-hour infusion has significant activity in metastatic breast cancer and is well tolerated at a dose of 100 mg/m²/wk or less, researchers from Memorial Sloan-Kettering Cancer Center reported at a poster session of the San Antonio Breast Cancer Symposium.
A group of French scientists concluded that oral vinorelbine (Navelbine) administered at a weekly dose of 80 mg/m² is well tolerated by patients with advanced breast cancer. While intravenous vinorelbine has previously proven to be highly effective
SAN ANTONIO-At almost three years' median follow-up, disease-free survival is 81% among a group of 42 women with resected breast cancer and four or more positive nodes who received dose-dense sequential chemotherapy using doxorubicin, paclitaxel (Taxol), and cyclophosphamide, Clifford A. Hudis, MD, said in his poster presentation.
ROME, Italy-The combination of paclitaxel (Taxol), fluorouracil (5-FU), and leucovorin, with G-CSF support, in pretreated patients with advanced breast cancer had a good toxicity profile and an encouraging response rate in a study from the Regina Elena Cancer Institute, Rome.
SAN ANTONIO--Two poster presentations at the San Antonio Breast Cancer Symposium suggest that breast tumors are more aggressive in African-American women than in Caucasian women.
DUARTE, Calif-Researchers at the City of Hope National Medical Center are in the process of updating their high-dose chemotherapy regimens for high-risk breast cancer patients to include paclitaxel (Taxol), George Somlo, MD, said in a poster presentation at the San Antonio Breast Cancer Symposium.
NOTTINGHAM, UK-Stable disease appears to be a clinically relevant category for judging the effectiveness of hormonal therapy in metastatic breast cancer, John Robertson, MD, said in his poster presentation of a study from the Department of Surgery, City Hospital, Nottingham.
NASHVILLE-In 1996, delivery difficulties were the major barrier to breast cancer gene therapy, Jeffrey T. Holt, MD, said at a plenary session of the San Antonio Breast Cancer Symposium.
SAN ANTONIO--Bisphosphon-ates are indicated in patients with established bone metastases from breast cancer or myeloma, to reduce skeletal complications, Alexander H.G. Paterson, MD, said at a minisymposium held in conjunction with the San Antonio Breast Cancer Symposium.
BOULOGNE, France-An oral formulation of vinorelbine (Navelbine) demonstrated encouraging antitumor activity and proved to be well tolerated in a phase I study of patients with advanced breast cancer, French physicians reported in a poster presentation.
ST. LOUIS-In a study of 31 breast cancer patients with chronic lymphedema who had failed other treatment methods, 27 showed significant improvement with use of the Reid Sleeve, a custom-designed pattern of soft polymer ridges that apply varying degrees of pressure, Diane Radford, MD, of Washington University, said in a poster presentation.
SAN ANTONIO-Although paclitaxel (Taxol) is still being evaluated as a single agent in advanced breast cancer, to determine optimal dosing and schedule, it is also being studied for use in combination with other cytotoxic agents, as adjuvant therapy in early-stage disease, and as part of high-dose chemotherapy regimens used with stem cell transplant.
SAN ANTONIO-Routine use of radiation therapy after breast-conserving surgery is a cost-effective strategy for improving outcome in breast cancer, a computerized decision-analysis study suggest.
The National Cancer Act of 1971 was established when then President Nixon declared the "war on cancer." Since that time, no magic bullet has been discovered, and it is apparent that we have not been victors in the war against the nation's second leading killer. Overall cancer rates have continued to rise, with only a slight decrease in mortality from breast and other cancers. Nevertheless, remarkable progress has been made in the cure of childhood cancers, Hodgkin's disease, and testicular cancer.[1,2]
