Multicenter Study Clinical TrialEfficacy and safety of the combination paclitaxel/carboplatin in patients with previously treated advanced ovarian carcinoma: a multicenter French Groupe des Investigateurs Nationaux pour l'Etude des Cancers Ovariens phase II study.
The French Groupe des Investigateurs Nationaux pour l'Etude des Cancers Ovariens (GINECO) conducted a multicenter phase II study of carboplatin and paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) to evaluate the efficacy and side effects of this combination in pretreated advanced ovarian cancer. Patients with progressive ovarian carcinoma during or after platinum-based chemotherapy received paclitaxel 175 mg/m2 intravenously over 3 hours followed by intravenous carboplatin over 30 minutes every 4 weeks. The dose of carboplatin was calculated using a projected area under the concentration-time curve of 5 mg/mL x min. ⋯ Transitory peripheral neuropathy was present in 45% of patients but was severe in only one patient. One early death was observed due to progressive disease and possibly to therapy. The combination of paclitaxel 175 mg/m2 as a 3-hour infusion and carboplatin dosed to an area under the concentration-time curve of 5 is an effective therapy in patients previously treated with platinum-based chemotherapy and may be administered safely to outpatients who relapse after one or two lines of chemotherapy.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialPaclitaxel with carboplatin versus paclitaxel with carboplatin alternating with cisplatin as first-line chemotherapy in advanced epithelial ovarian cancer: preliminary results of a Hellenic Cooperative Oncology Group study.
Ninety previously untreated patients with advanced epithelial ovarian cancer (International Federation of Gynecology and Obstetrics stages IIC, III, and IV) were randomized, after initial cytoreductive surgery, to receive paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) 175 mg/m2 as a 3-hour infusion with either carboplatin at an area under the concentration-time curve of 7 (group A) or carboplatin at an area under the concentration-time curve of 7 on courses 1, 3, and 5, alternating with cisplatin 75 mg/m2 on courses 2, 4, and 6 (group B). Treatment was given every 3 weeks, up to a total of six courses. Sixty-one patients (33 and 28 patients in groups A and B, respectively) had residual disease after the initial cytoreductive surgery. ⋯ Treatment was generally well tolerated. Grade 3 and 4 neutropenia was 20% and 32% for groups A and B, respectively, while grade 3 and 4 thrombocytopenia was 4% and 7%, respectively, with no significant difference between the two groups. In conclusion, both combinations seem very active for the treatment of advanced epithelial ovarian cancer and are associated with acceptable toxicity.

Multicenter Study Clinical TrialDose-escalated paclitaxel in 1-hour infusion with a fixed dose of cisplatin in previously untreated advanced ovarian cancer: a phase II trial of the Spanish Group for Ovarian Cancer.
This phase II trial was planned to study the efficacy and toxicity of a fixed dose of cisplatin plus paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) given over 1 hour with intrapatient dose escalation. Patients with advanced epithelial ovarian cancer (stages IIB-IV); Eastern Cooperative Oncology Group performance status < or = 2; normal renal, liver, and bone marrow function; and evaluable residual disease after debulking surgery were accrued. Paclitaxel was given over 1-hour infusion and dose was escalated from 175 to 200 and 225 mg/m2 if nadir neutrophil counts were > or = 1000/microL, platelets were > or = 100,000/microL, and neurotoxicity was less than grade 2. ⋯ Peripheral neurotoxicity (grade 1, 39.7%; grade 2, 42.6%; and grade 3, 8.8%) was dose-limiting. It is too early to report on time to progression and survival, and these data are not yet available. This combination of cisplatin with escalating doses of paclitaxel is feasible and very active, but the high incidence of peripheral neurotoxicity may limit its use.

Randomized Controlled Trial Multicenter Study Clinical TrialICON 2 and ICON 3 data in previously untreated ovarian cancer: results to date.
The second International Collaborative Ovarian Neoplasm study (ICON 2), was a large, international randomized study of cyclophosphamide/doxorubicin/cisplatin (CAP) versus single-agent carboplatin in patients with previously untreated ovarian cancer. Patients in the CAP arm received 500 mg/m2 cyclophosphamide, 50 mg/m2 doxorubicin, and 50 mg/m2 cisplatin. Carboplatin was dosed to an area under the concentration-time curve of 5. ⋯ In all, 1,070 patients have been entered to date. At the first planned interim analysis, in April 1996 in 434 patients, it was too early to provide efficacy data. The plan was to continue accruing to the trial to a maximum of 2,000 patients, with review in mid-1997, when the events for analysis will be virtually doubled and the data can be interpreted in light of the results of the Intergroup study (European Organization for Research and Treatment of Cancer, the National Cancer Institute of Canada, and the Scottish study) and Gynecologic Oncology Group trial 132.

Multicenter Study Clinical TrialPaclitaxel in platinum-resistant ovarian cancer patients. Argentine Multicenter Taxol Group.
Paclitaxel (Taxol; Bristol-Myers Squibb Company; Princeton, NJ) is an antineoplastic agent that inhibits microtubular function and has shown efficacy in several solid tumors, mainly ovarian tumors, in which 20% to 40% response rates in previously treated patients were observed. We conducted a study to assess survival, response rate, and toxicity associated with paclitaxel treatment in patients with advanced ovarian cancer resistant to platinum therapy. Between September 1994 and November 1996, 38 patients were admitted for study and 37 were evaluable. ⋯ Mild to moderate hematologic toxicity was observed with only one episode of grade 4 neutropenia, without fever. Gastrointestinal toxicity was moderate and peripheral neuropathy was mild, except for two patients who had concomitant pathologies or previous treatment, which might have caused some neuropathy. We concluded that paclitaxel given as a 3-hour infusion was easily administered for ambulatory treatment, with mild to moderate toxicity and promising results based on rate and duration of response as well as survival.
