[Cancer of the breast].
Breast cancer remains a key concern for oncologists. The possibility of tamoxifen treatment to prevent breast cancer in high-risk women was one of the central topics discussed for the 1992 ASCO edition. The rationale for the studies being developed in the US and Europe rests on experimental data and results of adjuvant hormone therapy trials. Decreased risks of cancer in the opposite breast, of cardiovascular disease, and of osteoporosis are effects that make tamoxifen extremely attractive for breast cancer prevention trials in postmenopausal women. In premenopausal women, however, preventive tamoxifen should be viewed with special caution because increased incidence of second cancers have been reported, although with dosages higher than those suggested for preventive therapy, and also because of difficulties with defining familial forms. The value of anthracyclines for adjuvant therapy has been demonstrated by several studies. Furthermore, a dose-response relationship has been reported with anthracyclines used as adjuvant therapy or in metastatic disease. New dose-limiting toxic effects, including thrombocytopenia and mucitis, develop when dosages are increased, with concomitant rG-CSF therapy. In patients with metastases, taxol seems to be a promising drug. Ongoing phase I trials seek to determine the optimal dosage and administration modalities for the taxol-doxorubicin combination.
