Objectives

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.

Entry Criteria

Disease Characteristics:


Histologically confirmed invasive ovarian cancer of epithelial origin

All tumor resected prior to randomization

Uncertain whether immediate chemotherapy is required


Prior/Concurrent Therapy:


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


Patient Characteristics:


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


Expected Enrollment

A maximum of 2,000 patients will be randomized.

Outline

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.

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.
