Randomized Controlled Trial Multicenter Study Clinical TrialCarboplatin plus paclitaxel as first-line chemotherapy in previously untreated advanced ovarian cancer. German AGO Study Group Ovarian Cancer. Arbeitsgemeinschaft Gynäkologische Onkologie.
Since publication of the results of the Gynecologic Oncology Group (GOG) III study, the combination of cisplatin and paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) has been adopted widely as the new standard for treating advanced ovarian cancer. Further attempts to optimize first-line chemotherapy with platinum and taxanes include substituting carboplatin for cisplatin, individualizing the carboplatin dose by calculating it according to the area under the concentration-time curve, and reducing the length of the paclitaxel infusion. Attempts to optimize platinum/paclitaxel combinations have led to the initiation of several small phase I/II trials evaluating the carboplatin/paclitaxel combination. ⋯ Retrospective comparison with the GOG results reveals no significant difference in response rates between patients in the cisplatin/paclitaxel arm of GOG III and those in the AGO study: the GOG study reported a 73% response rate, compared with a preliminary 75% response rate in the AGO study, resulting in a relative risk of 1.03 (95% confidence interval, 0.83 to 1.27). Overall, this interim analysis did not reveal any reason to terminate this study early. Accrual is ongoing and is expected to be completed in 1997.

Comparative Study Clinical TrialPaclitaxel by either 1-hour or 24-hour infusion in combination with carboplatin in advanced non-small cell lung cancer: preliminary results comparing sequential phase II trials.
Our group previously described the activity of carboplatin plus paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) (given as a 24-hour infusion) in 51 patients with advanced non-small cell lung cancer. To facilitate outpatient administration, the regimen was modified to infuse paclitaxel over 1 hour. Between February 1995 and August 1996, 63 patients with advanced non-small cell lung cancer were accrued by the Vanderbilt Cancer Center and its affiliate network. ⋯ Likewise, the incidence of grade 1 to 3 arthralgia/myalgia was greater among patients receiving 1-hour infusion of paclitaxel (3.5% v 28%). Although not randomized, these data suggest that survival may be comparable whether paclitaxel is given by short or prolonged infusion in advanced non-small cell lung cancer. Toxicity profiles differ, however, with greater myelosuppression following 24-hour paclitaxel, but a higher incidence of neurotoxicity and arthralgia/myalgia with the 1-hour infusion.

Randomized Controlled Trial Clinical TrialInduction paclitaxel and carboplatin followed by concurrent chemoradiotherapy in patients with unresectable, locally advanced non-small cell lung carcinoma: report of Fox Chase Cancer Center study 94-001.
The paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ)/carboplatin combination has demonstrated promising activity in patients with incurable non-small cell lung cancer (NSCLC). Our exploratory study is designed to evaluate the efficacy of this combination as induction therapy in patients with locally advanced NSCLC, to determine the maximally tolerated doses of paclitaxel and carboplatin administered every 3 weeks during radical thoracic radiation after induction treatment, and to determine the efficacy of granulocyte colony-stimulating factor (G-CSF) priming before induction treatment, followed by conventional G-CSF, compared with conventional G-CSF alone. Eligibility stipulated Karnofsky performance status > or =70%, < or =5% weight loss, and stages IIIB or bulky IIIA NSCLC. ⋯ Induction paclitaxel/carboplatin therapy is active and well tolerated by patients with locally advanced NSCLC. The maximum tolerated doses of paclitaxel and carboplatin during concurrent thoracic radiation and the role of G-CSF priming are not yet established. Severity of esophagitis corresponds to the extent of esophagus irradiated during concurrent thoracic radiotherapy and chemotherapy.

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.

Clinical TrialPaclitaxel (3-hour infusion) followed by carboplatin (24 hours after paclitaxel): a phase II study in advanced non-small cell lung cancer.
This phase II study was performed to investigate the efficacy of a 3-hour 225 mg/m2 paclitaxel infusion (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) followed 24 hours later by a 30-minute infusion of carboplatin (dosed to an area under the concentration-time curve of 6) in patients with stage IIIA, IIIB, or IV non-small cell lung cancer. Patients received chemotherapy and were monitored for toxicity, response, quality of life, and survival. Paclitaxel and carboplatin pharmacokinetics were also determined with the first cycle of chemotherapy. ⋯ Physical and emotional well-being improved in 57%, functional well-being in 43%, and social/family well-being in 14% of patients. Pharmacokinetic data are being analyzed by limited sampling technique to predict the paclitaxel area under the concentration-time curve. This unique schedule of paclitaxel and carboplatin is well tolerated and active, and is associated with improvements in various aspects of quality of life.
