A Randomized Controlled Trial Evaluating the Feasibility and Preliminary Efficacy of Pressurized Intraperitoneal Aerosol Chemotherapy (PIPAC) in Advanced Epithelial Ovarian Cancer

Inclusion criteria

• Patients with high-grade serous adenocarcinoma (HGSOC) with FIGO stage IIIC-IVA.
• Age between 18 and 70.
• Patients were evaluated with Fagotti score and MD Anderson score. MD Anderson score was consistent with Fagotti score ≥ 8, which was evaluated as high tumor load, because the initial curative resection could not achieve R0 resection and NACT was selected; or patients could not tolerate the initial surgery due to severe complications and NACT was selected.
• Normal renal function (blood creatinine: 58-96 μmol/L).
• No bone marrow suppression (HBG ≥ 110 g/L, white blood cell count ≥ 4.0×109/L, neutropenia Granulocyte count greater than or equal to 2.0x109/L and platelet count greater than or equal to 100x109/L).
• Normal liver function (bilirubin 3.4-22.2 μmol/L, ALT 7-40 U/L, AST 13-35 U/L, AST/ALT≤ 1.5）。
• World Health Organization Performance status score (WHO score) 0-2 points.

Exclusion criteria

• 1) Patients with other malignancies or have received any form of chemotherapy, radiotherapy and targeted therapy for this disease in other hospitals.

• Diagnose complete intestinal obstruction. 3) Subjects who rely entirely on parenteral nutrition. 4) Subjects with decompensated ascites; 5) Subjects with severe abdominal infection (peritonitis); 6) Subjects with extensive adhesions in the abdominal cavity; 7) Subjects who underwent tumor debulking surgery and gastrointestinal resection reconstruction simultaneously; 8) Subjects with portal vein thrombosis; 9) Patients with severe or uncontrolled medical conditions and infections (including atrial fibrillation, angina pectoris, heart Functional insufficiency, ejection fraction less than 50%, difficult to control hypertension, etc.); 10) Allergy to chemotherapy drugs in the past; 11) Patients with serious cardiopulmonary, liver and kidney, blood system or mental illness and drug abuse; 12) Expected life is less than 12 weeks. 13) Patients who have participated or are currently participating in other clinical trials within 3 months; 14）Other conditions that the researchers judged the patient to be unsuitable for inclusion.
