• Overall survival as measured by Kaplan Meier every 3 months for 2 years, every 6 months for 3 years, and then annually [ Designated as safety issue: No ]
  

• Progression-free survival as measured by Kaplan Meier and RECIST every 3 months for 2 years, every 6 months for 3 years, and then annually [ Designated as safety issue: No ]
  
• Health-related quality of life as measured by Quality of Life Questionnaire-C30 after courses 1, 3 and 6, then at 6 and 12 months [ Designated as safety issue: No ]
  
• Toxicity as measured by NCIC Common Toxicity Criteria v2.0 within 4 weeks of surgery [ Designated as safety issue: Yes ]
  

OBJECTIVES:

• Compare the overall survival and progression-free survival in patients with stage IIIC or IV ovarian epithelial, peritoneal, or fallopian tube carcinoma treated with neoadjuvant chemotherapy followed by interval debulking surgery versus upfront cytoreductive surgery followed by chemotherapy with or without interval debulking surgery.
• Compare the quality of life of patients treated with these regimens.
• Compare the different treatment complications in patients treated with these regimens.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to participating center, method of biopsy, stage, largest tumor size before surgery, and intent to also randomize on EORTC-55012. Patients are randomized to one of two treatment arms.

• Arm I: Patients undergo upfront maximal cytoreductive surgery followed by cisplatin or carboplatin IV every 3 weeks for 3 courses. Patients with non-optimal primary debulking may undergo interval debulking surgery at the physician's discretion. All patients then receive an additional 3 courses of the same regimen of chemotherapy.
• Arm II: Patients receive chemotherapy as in arm I. Patients with stable or responding disease undergo interval debulking surgery followed by an additional 3 courses of the same regimen of chemotherapy.

Second-look surgery is allowed for both arms if clinically indicated.

Quality of life (QOL) is assessed prior to treatment, after the third and sixth course of chemotherapy, and at 6 and 12 months after study. Patients who are also randomized on EORTC-55012 follow the QOL assessment schedule for EORTC-55012 only.

Patients are followed every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 704 patients will be accrued for this study within 4 years.
