From January 2015 to February 2019, 123 patients with stages IIIC-IV ovarian cancer were treated with neoadjuvant chemotherapy (NAC) followed by IDS with optimal cytoreduction. Forty-three patients received IDS with HIPEC and 80 patients had IDS without HIPEC. The median follow-up period was 34.4 months. No differences in baseline characteristics in patients were found between the two groups. The IDS with HIPEC group had fewer median cycles of chemotherapy (P = 0.002) than the IDS group. The IDS with HIPEC group had a higher rate of high surgical complexity score (P = 0.032) and higher rate of complete resection (P = 0.041) compared to the IDS group. The times to start adjuvant chemotherapy were longer in the IDS with HIPEC group compared to the IDS group (P < 0.001). Postoperative grade 3 or 4 complications were similar in the two groups (P = 0.237). Kaplan-Meier analysis showed that HIPEC with the IDS group had better progression-free survival (PFS) (P = 0.010), while there was no difference in overall survival between the two groups (P = 0.142). In the multivariate analysis, HIPEC was significantly associated with better PFS (HR, 0.60; 95% CI, 0.39 - 0.93). The addition of HIPEC to IDS resulted in longer PFS than IDS without HIPEC not affecting the safety profile. Further research is needed to evaluate the true place of HIPEC in the era of targeted treatments.","claims":[{"public_id":"cl_db48d59aef7f464f0dbc773481f2a28d","status":"active","text":"Adding
