ReviewHigh-dose therapy with carboplatin and paclitaxel in non-small cell lung cancer.
Non-small cell lung cancer (NSCLC) remains the leading cause of cancer deaths in the United States. The combination of more active agents like vinorelbine and paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) with cisplatin has led to improved survival for patients with advanced metastatic disease. The ability to escalate the dose of cisplatin-based regimens is limited by nonhematologic toxicities and is especially difficult in the population of patients with advanced NSCLC. ⋯ Depending on response to induction therapy, patients then receive surgical resection, thoracic radiation therapy, or both. This phase II trial will examine clinical and pathologic responses and the toxicity of this high-dose regimen in patients with locally advanced NSCLC. Ultimately, phase III trials will be needed to establish the role of this approach in NSCLC.

ReviewDocetaxel in combination chemotherapy for metastatic breast cancer.
Due to its novel mechanism of action, docetaxel has significant in vitro activity against a variety of solid tumors, including breast cancer. In phase II clinical trials, docetaxel 100 mg/m2 every 3 weeks has shown substantial single-agent activity in patients with both previously untreated and heavily pretreated metastatic breast cancer. As single-agent chemotherapy is rarely curative in this setting, docetaxel has been combined with other anticancer agents with proven efficacy against breast cancer (doxorubicin, vinorelbine, fluorouracil, cyclophosphamide, cisplatin, and doxorubicin plus cyclophosphamide) in an attempt to increase efficacy and prolong patient survival. ⋯ Combination studies with fluorouracil, cisplatin, and cyclophosphamide, and a study of sequential administration with doxorubicin + cyclophosphamide, are ongoing. Interim results indicate that these docetaxel-based combinations have acceptable safety profiles and encouraging levels of antitumor activity. The full results of these studies will help to elucidate the potential contribution of docetaxel-based combination chemotherapy to the management of metastatic breast cancer.

ReviewDefining the role of paclitaxel in lung cancer: summary of recent studies and implications for future directions.
Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) was first reported to have activity in advanced non-small cell lung cancer (NSCLC) in 1993 and in advanced small cell lung cancer (SCLC) in 1995. Since these original reports, single-agent activity has been confirmed in both NSCLC and SCLC. In NSCLC, the 20% to 25% response rate and median survival times (approximately 40 weeks) are superior to previously reported single-agent therapy. ⋯ Similarly, paclitaxel and carboplatin combinations produce high response rates when given before surgery for operable patients, and the results of randomized trials are needed to confirm the value of this approach. Paclitaxel-based combinations in advanced SCLC can be administered safely and provide high response rates and relatively long survival times. Randomized trials comparing these combinations to older etoposide/cisplatin combinations are in progress.

ReviewFuture perspectives of docetaxel (Taxotere) in front-line therapy.
The recognition that early breast cancer is a systemic disease has led to the development of multimodal treatments incorporating adjuvant hormonal and chemotherapies. Adjuvant strategies have improved the outcome of treatment for early breast cancer, but 50% of women still relapse and develop overt metastatic disease, which is largely incurable. In the search for more effective chemotherapies, the taxoid, docetaxel (Taxotere; Rhône-Poulenc Rorer, Antony, France), has demonstrated high single-agent activity against metastatic breast cancer, including visceral metastases, and is now in phase III trials of combination adjuvant and front-line therapies. ⋯ The high single-agent activity of docetaxel makes it an excellent candidate for treatments such as induction regimens before high-dose chemotherapy and adjuvant therapies. Short-term treatment regimens such as these should also avoid the cumulative toxicities of docetaxel. It is important that new drugs, such as docetaxel, which have shown promising activity against metastatic disease and could have a significant impact on the natural history of early breast cancer, are investigated as front-line treatments.

Multicenter Study Clinical TrialPaclitaxel (1-hour infusion) plus carboplatin in the treatment of advanced non-small cell lung cancer: results of a multicenter phase II trial.
This study was performed to determine the activity and toxicity of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) given by 1-hour infusion plus carboplatin in the treatment of patients with advanced non-small cell lung cancer when used in a multicenter, community-based setting. The study population included 100 chemotherapy-naive patientswith stage IIIB or IV non-small cell lung cancer, Karnofsky performance status 70 to 100, measurable disease, and adequate kidney, liver, and bone marrow function. All patients received paclitaxel 225 mg/m2 intravenously by 1-hour infusion followed immediately by carboplatin at a targeted area under the concentration-time curve of 6.0 (Calvert formula). ⋯ One patient died as a result of treatment due to sepsis. This large, multicenter, community-based phase II trial demonstrates the efficacy of paclitaxel/carboplatin combination chemotherapy in advanced non-small cell lung cancer. This regimen is relatively well tolerated and when paclitaxel is given by 1-hour infusion, this treatment is easily administered in the outpatient setting.
