About

This is an open-label, multicenter, single-arm, feasibility phase 2 trial on safety and efficacy of short-course regimen of intra-operative Hyperthermic Intraperitoneal Chemotherapy (HIPEC) at the time of fast-track interval debulking surgery (IDS) following neoadjuvant chemotherapy (NACT) for high tumor burden epithelial ovarian cancer (EOC).

Full description

This study was initially designed to explore the safety and efficacy of short-course HIPEC in terms of median progression-free survival (PFS) as the primary outcome. However, due to slow accrual, the design was subsequently amended to explore the primary outcome measure of PD9 (i.e.: proportion of patients with disease progression or death occurring within 9 months of IDS plus HIPEC). The hypothesis was the short-course HIPEC could decrease PD9 with low rates of morbidity and mortality. In these settings, we explore a comprehensive treatment approach involving fast-track advanced cytoreductive surgery (CRS) plus short-course HIPEC at the time of IDS following NACT for high tumor burden patients with stage III-IV ovarian cancer. Advanced CRS was performed with standard peritonectomy procedures and visceral resections directed towards complete elimination of tumors from the abdominopelvic cavity, and fast-track recovery strategies were also applied to improve patient outcomes. HIPEC was performed according to the closed-abdomen technique using CDDP (25 mg/L of perfusate/m2, total limit of 240mg) or CDDP plus Doxorubicin (15mg/L) for 30 minutes, with an intra-abdominal target temperature of 41-43°C. Perfusate (2L/m2, ranging from 4L to 6L) was circulated using an extracorporeal circulation device (Performer HT; RAND, Medolla, Italy) at a flow rate of 700 ml/min. Systemic chemotherapy included the standard combination of carboplatin and paclitaxel as neo-adjuvant plus adjuvant regimens.
