HIPEC in Ovarian Cancer: When and to Whom? | LitMetric

Objective: To evaluate the optimal candidates for hyperthermic intraperitoneal chemotherapy (HIPEC) and cytoreductive surgery (CRS) in ovarian cancer.

Study Design: Descriptive study. Place and Duration of the Study: Health Sciences University, Dr. Abdurrahman Yurtasian Ankara Oncology Training and Research Hospital, Ankara, Turkey, between 2013 and 2021.

Methodology: Ovarian cancer patients who underwent HIPEC and CRS for peritoneal involvement were included in this study. Thermosolutions were prepared as a closed system by using HT 2000 hyperthermic perfusion device. Then, cisplatin was applied at 100 mg/m2 at 42-42.5 °C for 60 minutes after CRS.

Results: A total of 47 patients were enrolled. The median age was 54 years (27-80) at the time of diagnosis. Forty (85.1%) patients had high grade serous carcinoma and 22 (46.7%) patients had clinical stage 3C disease. The median peritoneal cancer index (PCI) was 13 (3-24) in the whole population. HIPEC was applied as first-line treatment in 25 (51%) patients. Eleven (23.4%) patients had HIPEC in the post-neoadjuvant interval whereas 10 (21.3%) patients had it in platinum sensitive relapse. Median progression free survival (PFS) was 31(95% CI:11-50), 33 (95% CI:1-67), and 18 (95% CI:8-27) months in the primary, post-neoadjuvant interval, and platinum-sensitive relapse HIPEC groups, respectively. The patients with lower PCI (PCI<13) had significantly better OS than others with higher PCI (PCI>13, 145 months versus 42 months, p=0.034).

Conclusion: HIPEC with CRS should be considered in selected serous carcinoma patients with peritoneal involvement, especially for the patients with primary ovarian cancer with lower PCI (PCI<13).

Key Words: Ovarian cancer, HIPEC, Peritoneal cancer index.
