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.

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 Clinical TrialPaclitaxel (175 mg/m2 over 3 hours) with cisplatin or carboplatin in previously untreated ovarian cancer: an interim analysis.
The side effects of cisplatin (75 mg/m2) in combination with paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) (175 mg/m2 over 3 hours) are expected to be more severe and frequent than those of carboplatin (area under the concentration-time curve of 5) in combination with the same dose of paclitaxel, but the combinations are expected to be equally effective. A disadvantage of the cisplatin-based regimen is that patients need to be admitted to the hospital. The carboplatin regimen can be administered to outpatients. ⋯ An interim analysis for toxicity was performed in 145 patients shortly after study closure. We observed a difference in the incidence of nausea, vomiting, and neurotoxicity favoring the women treated with the carboplatin regimen, but this regimen caused more myelotoxicity. Maturation of the study is awaited before survival data can be analyzed and final conclusions can be drawn.

Carboplatin plus paclitaxel in the treatment of gynecologic malignancies: the Cleveland Clinic experience.
To examine the toxicity profile and antineoplastic activity of carboplatin (area under the concentration-time curve of 4 to 7.5) plus 3-hour infusional paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) (135 or 175 mg/m2) in women with advanced gynecologic malignancies, we retrospectively reviewed the experience of the Gynecologic Cancer Program at The Cleveland Clinic with this combination chemotherapy regimen. To date, 92 patients (median age, 67 years) have received a total of 460 courses (median number per patient, six) of this two-drug combination. The initial paclitaxel dose was 175 mg/m2 and the carboplatin area under the concentration-time curve was > or = 5 in 72% and 73% of patients, respectively. ⋯ Twelve patients (13%) experienced at least one episode of paclitaxel-associated hypersensitivity, but all were able to continue with the treatment program. Of the 62 patients with ovarian cancer or primary peritoneal carcinoma with carbohydrate antigen-125 levels > or = 60 U/mL before the initiation of chemotherapy, 74% exhibited a > or = 90% decline in the tumor marker following treatment. We conclude that the combination of carboplatin and 3-hour infusional paclitaxel can be administered in the outpatient setting with a highly acceptable toxicity profile and with major activity in patients with ovarian cancer and primary carcinoma of the peritoneum.

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.
