Randomized Controlled Trial Clinical TrialPaclitaxel (175 mg/m2) plus carboplatin versus paclitaxel (225 mg/m2) plus carboplatin in non-small cell lung cancer: a randomized study.
A recent phase II study by our group documented a response rate of 27% with the combination paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) 175 mg/m2 plus carboplatin dosed to a target area under the concentration-time curve of 7 in patients with advanced non-small cell lung cancer. In an effort to evaluate the dose-response relationship of paclitaxel with quality of life, we initiated a phase III prospective trial. Patients with inoperable non-small cell lung cancer were randomized into two groups. ⋯ There were no drug-related deaths. It is too early to draw definite conclusions regarding response and survival, but regarding toxicity, it seems that paclitaxel 225 mg/m2 plus carboplatin dosed to an area under the concentration-time curve of 6 is well tolerated without the use of growth factors. Although the results are premature, quality of life does not seem to be affected by the increased paclitaxel dose.

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.

Multicenter Study Clinical TrialDocetaxel (Taxotere) and gemcitabine in the treatment of non-small cell lung cancer: preliminary results.
A phase II study was performed to investigate the tolerance and efficacy of the combination of docetaxel (Taxotere; Rhône-Poulenc Rorer, Antony, France) and gemcitabine in chemotherapy-naive patients with advanced non-small cell lung cancer (NSCLC). To date, 24 patients (five with stage IIIB and 19 with stage IV NSCLC) have been treated according to the protocol: gemcitabine 900 mg/m2 was administered on days 1 and 8 as a 30-minute infusion and docetaxel 100 mg/m2 was administered on day 8 as a 1-hour infusion after appropriate premedication. Granulocyte colony-stimulating factor 150 microg/m2 subcutaneously was given on days 9 to 15. ⋯ The median delivered dose was 600 mg/m2/wk and 33 mg/m2/wk for gemcitabine and docetaxel, respectively. These preliminary data suggest that the docetaxel/gemcitabine combination has significant antitumor activity and is well tolerated in chemotherapy-naive patients with NSCLC. The study is ongoing.

Clinical TrialPreliminary results of a phase II study of paclitaxel and cisplatin in patients with non-small cell lung cancer.
Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) and cisplatin are cytotoxic drugs active against non-small cell lung cancer (NSCLC) that possess additive cytotoxicity in animal tumors. Paclitaxel and cisplatin are active in patients with advanced NSCLC when given on a 3-weekly schedule. In an attempt to increase activity, we designed a phase II study with a biweekly schedule. ⋯ Median response duration was 31 weeks (range, 9 to 85 weeks). The biweekly schedule of paclitaxel plus cisplatin has noteworthy activity in patients with NSCLC. A relatively large fraction of patients required either dose reduction and/or treatment delay, but World Health Organization grade 3 or 4 toxicity was rare, apart from the neutropenia that caused only a few septicemic episodes.

Randomized Controlled Trial Clinical TrialThe role of docetaxel (Taxotere) as a single agent or in combination before local treatment of non-small cell lung cancer.
Neoadjuvant therapy in the treatment of stage IIIa/b non-small cell lung cancer (NSCLC) has the potential to reduce tumor size in patients whose tumors were previously inoperable. This report describes the design and status of an ongoing randomized, phase III study of docetaxel (Taxotere; Rhône-Poulenc Rorer, Antony, France) as neoadjuvant treatment in patients with stage IIIa/b NSCLC, as well as of two phase II studies of combination neoadjuvant therapies. A phase III, multicenter, international, randomized trial is in progress which compares docetaxel with no neoadjuvant chemotherapy in patients with histologically confirmed, previously untreated NSCLC with stage IIIa N2(T0-3) or T3 (N0-1) disease or stage IIIb disease that can be treated radically. ⋯ The primary objective of the study is to determine the response rate after chemotherapy. The results of both studies should be available by late 1997. The ultimate hope is that there is potential for neoadjuvant chemotherapy to provide a significant benefit for patients with advanced NSCLC.
