First-line Intraperitoneal Cisplatin and Etoposide Chemotherapy for Ovarian Cancer

This exploratory trial is to compare the efficacy of sequential chemotherapy, intraperitoneal chemotherapy followed by intravenous chemotherapy, versus intravenous chemotherapy alone in the first-line therapy for ovarian cancer.

Inclusion criteria

• Age ≥18 years to ≤ 75 years.
• Epithelial ovarian cancer with pathology confirmed stage IIIc or IV, expect for lymph node metastasis alone
• Optimal cytoreductive surgery, including hysterectomy, bilateral salpinges-oophorectomy, omentectomy, and resection of all metastatic lesions, with a residual disease no more than 1cm
• Available to receive intraperitoneal chemotherapy 5-10 days postoperative, or no more than postoperative 14 days for those with bowel resection.
• ECOG performance 0-2.
• No more than 3 cycles of chemotherapy prior to surgery.
• Laboratory testing within 7 days of registration: hematopoietic: absolute neutrophil count greater than 1,500/mm3; Platelet count greater than 100,000/mm3. Hepatic: bilirubin less than 1.25 times upper limit of normal (ULN); Bilirubin < 2.0, SGPT less than 2 times ULN. Renal: creatinine less than 1.6 mg/dL, OR creatinine clearance greater than 40 mL/min.
• Comply with intraperitoneal chemotherapy and follow-up.
• Written informed consent.

Exclusion criteria

• Low-malignant potential ovarian tumor.
• Laboratory testing insufficiency. Hemoglobin < 10 g/dL. Renal insufficiency with serum creatinine > 1.6.
• Bone marrow dysfunction: absolute neutrophil count less than 1,500/mm3; Platelet count less than 80,000/mm3.
• Active infection.
• Clinically significant gastrointestinal abnormalities.
• Active coronary artery disease, cerebrovascular disease, restrictive or obstructive pulmonary disease, or congestive heart failure.
• Other condition that could interfere with provision of informed consent, compliance to study procedures, or follow-up.
• Prior invasive malignancies within the last 5 years showing activity of disease.
