Background:
To investigate outcomes and morbidity of patients undergoing secondary cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in recurrent ovarian cancer.
Materials And Methods:
Between April 2014 and January 2019, a total of 51 recurrent ovarian cancer patients receiving secondary CRS and HIPEC were retrospectively reviewed.
Results:
Among the 51 patients, median peritoneal cancer index score was 13 (range 3-34), and completeness of cytoreduction (CC) score of 0/1 was achieved in 41 patients (78.8%). Regimen of HIPEC included cisplatin and paclitaxel in 39 (75%) cases. The median follow-up duration of survivors was 20.2 months. Sixteen (30.8%) patients remained free of recurrence after HIPEC. The median progression-free survival (PFS) and overall survival (OS) were 11.8 months and 34.5 months respectively. Multivariate analysis showed previous chemotherapy <2 lines (HR 0.24, 0.11-0.52; p = 0.001), chemotherapy-free interval ≥6 months (HR 0.19, 0.09-0.37; p < 0.001) and CA125 < 35 U/mL before HIPEC (HR 0.133, 0.021-0.0832; p = 0.031) were good prognostic factors for PFS. CC0/1 was not significant in multivariate analysis. The most common grade 3/4 toxicity was anemia (17.3%), pleural effusion (11.5%) and renal insufficiency (5.7%). Patients with age ≥50, peritoneal carcinomatosis index (PCI) ≥ 11, operation time ≥10 h and diaphragm surgery had significantly higher incidence of pleural effusion.
Conclusions:
The current study showed adding HIPEC to secondary CRS might prolong PFS especially in patients with previous chemotherapy <2 lines, chemotherapy-free interval ≥6 months and CA125 < 35 U/mL before HIPEC.
