- Brief Summary
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).
- Detailed 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.

- Primary Outcome Measures
Name Time Method PD9 9 months Proportion of patients with disease progression or death occurring within 9 months of IDS plus HIPEC
- Secondary Outcome Measures
Name Time Method Assessment of quality of life (QLQ-C30/EORTC) Baseline (i.e., at the time of hospital admission for IDS plus HIPEC); after CRS/HIPEC (i.e., at the time of restarting the systemic chemotherapy); after protocol (i.e., at 3-6 weeks after the last syst Assessment of quality of life according to the QLQ-C30/EORTC scales.
Disease-free Survival (DFS) 24 months We defined DFS for patients without no gross residual disease as the time from IDS plus HIPEC to disease progression.
Postoperative 30-day mortality rate 30 days Mortality rates up to 30-day after surgery
Postoperative complication rates 30 days Complications rates up to 30-day after surgery
Overall survival (OS) 24 months We defined OS as the time from starting the NACT to death.
Progression-free Survival (PFS) 24 months We defined PFS as the time from starting the NACT to disease progression.
