The proven safety profile and antitumor activity of paclitaxel (Taxol) in the treatment of metastatic breast cancer led investigators at Memorial Sloan-Kettering Cancer Center (MSKCC) to further examine the agent's potential in the treatment of advanced breast cancer. Efficacy and tolerability studies of paclitaxel as single-agent therapy were undertaken, along with parallel investigations of quality-of-life parameters. The studies examined the effects of 96-hour infusion schedules of paclitaxel and are currently assessing the feasibility of a weekly 1-hour infusion schedule. Researchers at MSKCC also compared the results of a variety of two- and three-drug paclitaxel-containing regimens to determine possible synergism and better define safety profiles. They examined the combination of paclitaxel and edatrexate, as well as a promising combination of paclitaxel and a monoclonal antibody directed at growth factor receptors. The latter ongoing trial will include both laboratory studies that examine possible cellular mechanisms for the combination's observed synergy and a clinical trial that combines paclitaxel with a monoclonal antibody directed against the epidermal growth factor. In conclusion, the investigators discuss the optimal integration of paclitaxel into doxorubicin/cyclophosphamide (Cytoxan, Neosar)-based adjuvant therapy for node-positive stage II-III resectable breast cancer.
