I. Determine whether adjuvant chemotherapy with a platinum-containing regimen (e.g., carboplatin or CAP: cyclophosphamide/doxorubicin/cisplatin) prolongs survival in patients with early stage ovarian cancer compared to those receiving no adjuvant treatment.
Histologically confirmed invasive ovarian cancer of epithelial origin All tumor resected prior to randomization Uncertain whether immediate chemotherapy is required
Biologic therapy: Not specified Chemotherapy: No prior chemotherapy Endocrine therapy: Not specified Radiotherapy: No prior radiotherapy Surgery: Minimum recommended surgical procedures (when possible): Thorough surgical staging Total hysterectomy/bilateral salpingo-oophorectomy Omentectomy, as follows: Total supracolonic omentectomy if omentum involved Removal of distal 2 cm or infracolonic omentectomy in the absence of macroscopic disease
Age: Any age Performance status: Sufficient to receive chemotherapy Hematopoietic: Not specified Hepatic: Not specified Renal: Not specified Other: No prior malignancy except nonmelanomatous skin cancer No clear contraindication to chemotherapy
A maximum of 2,000 patients will be randomized.
Randomized study. Patients are randomized to Arm I or II; treatment should begin within 6 weeks of surgery. Regimens listed in Arm I are recommended, but other platinum-containing regimens are allowed provided the doses at a minimum meet those listed below. Arm I: Single-agent Chemotherapy or 3-Drug Combination Chemotherapy. Carboplatin, CBDCA, NSC-241240; or CAP: Cyclophosphamide, CTX, NSC-26271; Doxorubicin, DOX, NSC-123127; Cisplatin, CDDP, NSC-119875. Arm II: Observation. No adjuvant therapy.Published Results

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol.
