Summary

Ovarian cancer is among the top five primary causes of cancer-related mortality in women. Most ovarian malignant tumours originate from epithelial cells The majority of patients typically have advanced-stage tumours at diagnosis. When complete surgery with no macroscopic visible disease is not feasible due to both the spread of the disease and the patient's general condition, neoadjuvant chemotherapy (NACT) of 3 cycles followed by interval cytoreductive surgery (ICS) or final cytoreductive surgery (FCS) after 6 cycles of NACT followed or not by adjuvant chemotherapy can be offered, with similar overall survival. In our centre, due to logistics, disease, or patient factors, many patients may receive more than 3 cycles of NACT before ICS. Therefore, this randomized controlled trial aims to evaluate the survival benefit of different timings of ICS after 3 or 6 cycles of NACT in patients not eligible for upfront cytoreductive surgery (UCS).

Interventions

Type	Name	Description
PROCEDURE	Delayed interval cytoreductive surgery (DICS)	patients will receive six courses of intravenous carboplatin and paclitaxel every 3 weeks, followed by delayed interval cytoreductive surgery (DICS) within 6 weeks of the last cycle of chemotherapy. After DICS, patients will be assessed for the need or not for further adjuvant chemotherapy. chemotherapy regimen: * Paclitaxel at 175 mg/m² + carboplatin area under the curve (AUC) 5-6 every 3 weeks. * Paclitaxel at 60 mg/m² (days 1, 8, and 15), and carboplatin AUC 2 (days 1, 8, and 15) every 3 weeks. * Paclitaxel at dense dose 80 mg/m² (days 1, 8, and 15) and carboplatin AUC 5-6 (day 1) every 3 weeks.
PROCEDURE	Early interval cytoreductive surgery (EICS)	patients will receive three courses of intravenous carboplatin and paclitaxel every 3 weeks, followed by early interval cytoreductive surgery (EICS) within 6 weeks of the last cycle of chemotherapy. After EICS, patients will receive adjuvant three courses of intravenous carboplatin and paclitaxel every 3 weeks, then will be assessed for the need or not for further adjuvant chemotherapy. chemotherapy regimen: * Paclitaxel at 175 mg/m² + carboplatin area under the curve (AUC) 5-6 every 3 weeks. * Paclitaxel at 60 mg/m² (days 1, 8, and 15), and carboplatin AUC 2 (days 1, 8, and 15) every 3 weeks. * Paclitaxel at dense dose 80 mg/m² (days 1, 8, and 15) and carboplatin AUC 5-6 (day 1) every 3 weeks.
