Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialA three-arm trial of vinorelbine (Navelbine) plus cisplatin, vindesine plus cisplatin, and single-agent vinorelbine in the treatment of non-small cell lung cancer: an expanded analysis.
Phase II studies have demonstrated that vinorelbine (Navelbine; Burroughs Wellcome Co, Research Triangle Park, NC; Pierre Fabre Médicament, Paris, France) alone or in combination with cisplatin has promising activity against non-small cell lung cancer (NSCLC). On the basis of these preliminary trials, a phase III study was designed to compare intravenous vinorelbine (30 mg/m2 weekly) plus cisplatin (120 mg/m2 on day 1 and day 29 and then every 6 weeks) with vindesine (3 mg/m2 weekly for 6 weeks and then every 2 weeks) plus cisplatin, and to evaluate whether the best of these regimens afforded a survival benefit compared with intravenous vinorelbine alone, an outpatient regimen. This report presents an expanded analysis of data from this previously published study. ⋯ The major difference in survival between the two cisplatin-containing regimens occurred in patients with metastatic (stage IV) NSCLC. The incidence of granulocytopenia was significantly higher in the vinorelbine plus cisplatin arm compared with the other two treatment groups, but neurotoxicity was significantly more frequent in the vindesine plus cisplatin group. The results of this study indicate that the combination of vinorelbine plus cisplatin is a viable treatment option for patients with NSCLC and may provide advantages compared with other commonly used regimens.

Multicenter Study Clinical TrialPreliminary results of two dose-finding studies of paclitaxel (Taxol) and carboplatin in non-small cell lung and ovarian cancers: a European Cancer Centre effort.
Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) given as a 24-hour infusion, and carboplatin have activity in advanced non-small cell lung cancer (NSCLC) and ovarian cancer. Two dose-finding studies were initiated to identify the optimal doses for the paclitaxel/carboplatin combination when paclitaxel is given in a 3-hour infusion. The fact that the pharmacologic interaction between paclitaxel and cisplatin increases the toxicity of paclitaxel when cisplatin is given before it also prompted an investigation of the influence of drug sequence on toxicity and pharmacokinetics in the NSCLC trial. ⋯ No difference in toxicity has been observed thus far between the two drug sequences in the NSCLC study. Both studies are still accruing patients as the maximum tolerated doses of paclitaxel in combination with carboplatin have not yet been reached (carboplatin 300 mg/m2 with paclitaxel 175 mg/m2 in the NSCLC study; carboplatin 400 mg/m2 with paclitaxel 150 mg/m2 in the ovarian cancer study). An investigation of maximum tolerated doses with granulocyte colony-stimulating factor support is planned thereafter.

Randomized Controlled Trial Clinical TrialA phase II study of cisplatin, 5-fluorouracil, and leucovorin augmented by vinorelbine (Navelbine) for advanced non-small cell lung cancer: rationale and study design.
In a randomized phase II study by the Cancer and Leukemia Group B, the cisplatin/5-fluorouracil/leucovorin (PFL) combination produced a 29% response rate in advanced, unresectable non-small cell lung cancer. Vinorelbine (Navelbine; Burroughs Wellcome, Co, Research Triangle Park, NC; Pierre Fabre Médicament, Paris, France), a semisynthetic vinca alkaloid, has also demonstrated single-agent activity in this disease. Therefore, a phase I-II study was designed to investigate the addition of vinorelbine in escalating doses to the PFL combination. ⋯ It was concluded that this dose level was not feasible. During a preliminary analysis, one complete response and three partial responses were observed in 16 patients evaluated; one of these patients had a pathologic complete remission. This early analysis indicates activity for the regimen.

Clinical Trial Controlled Clinical TrialHigh-dose ifosfamide/carboplatin/etoposide: maximum tolerable doses, toxicities, and hematopoietic recovery after autologous stem cell reinfusion.
We treated 115 patients in a phase I/II dose-escalation study of ifosfamide/carboplatin/etoposide (ICE) followed by autologous stem cell rescue. Patients treated had a variety of diagnoses, including breast cancer (high-risk stage II disease with eight or more positive nodes, stage III disease, and responsive metastatic disease), non-Hodgkin's lymphoma, Hodgkin's disease, acute leukemia in first remission, and various solid tumors that were responsive to induction therapy. Patients received autologous bone marrow stem cells or peripheral blood stem cells primed by one of several methods. ⋯ Neutrophil recovery times varied based on the source of stem cells used, with the earliest engraftment times seen for patients receiving peripheral blood stem cells primed with cyclophosphamide and granulocyte colony-stimulating factor. Platelet recovery times were not statistically different for any of the subsets. In conclusion, the maximum tolerated dose of ICE has been defined, and the source of stem cells and the use of hematopoietic growth factors influence hematopoietic recovery.

Clinical TrialCarboplatin and radiotherapy in the treatment of head and neck cancer: six years' experience.
Between 1987 and 1991, 103 patients with advanced head and neck carcinoma were treated with radiochemotherapy plus carboplatin. Tumors were located in the oral cavity in 33 patients, the oropharynx in eight, and the hypopharynx in seven. Four patients had a tumor of the epipharynx and three, tumor of the larynx. ⋯ Patients with advanced head and neck carcinomas are either randomized for conventional radiotherapy plus carboplatin or hyperfractionated accelerated irradiation plus carboplatin. As of July 1994, 178 patients have been entered in the study. Results will be evaluated after the study is completed.
