RESUMEN
AIM: To evaluate the effect of secondary cytoreductive surgery (SeCRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) in recurrent epithelial ovarian cancer patients. METHODS: This retrospective study analyzed a prospective database. We collected information of 389 patients who were diagnosed with recurrent epithelial ovarian cancer. All patients underwent SeCRS with or without HIPEC. Overall survival and progression-free survival (PFS) were used to evaluate the treatment effectiveness. RESULTS: Of the 389 patients collected, 123 underwent primary or interval cytoreductive surgery at initial treatment and SeCRS at recurrence (Group A), 130 underwent primary or interval cytoreductive surgery at initial and SeCRS plus HIPEC at recurrence (Group B), and 136 underwent primary or interval cytoreductive surgery plus HIPEC at initial and SeCRS plus HIPEC at recurrence (Group C). The median overall survival for Groups A, B, and C were 49.1 months (95% confidence interval [CI]: 47.6-50.5), 56.0 months (95% CI: 54.2-57.7), and 64.4 months (95% CI: 63.1-65.6), respectively. The median PFS for Groups A, B, and C were 13.1 months (95% CI: 12.6-13.5), 15.0 months (95% CI: 14.2-15.7), and 16.8 months (95% CI: 16.1-17.4), respectively. There were no significant difference in incidence and grade of adverse events among groups. CONCLUSIONS: This study suggested that SeCRS plus HIPEC followed by chemotherapy resulted in longer overall survival and PFS than only SeCRS followed by chemotherapy in patients with recurrent ovarian cancer, especially in patients who were treated with repeat HIPEC.

OBJECTIVE: To evaluate the effect of secondary cytoreductive surgery (SeCRS) followed by platinum-based chemotherapy (PBC) and olaparib tablets as maintenance therapy in patients with BRCA mutated recurrent epithelial ovarian cancer. METHODS: This was a retrospective study of a prospective database. We collected information on 623 patients diagnosed with BRCA mutated recurrent epithelial ovarian cancer, all of whom underwent SeCRS followed by PBC in combination with or without olaparib. Overall survival and progression-free survival were measured to evaluate treatment effectiveness. RESULTS: Of the 623 patients recruited, 240 underwent SeCRS plus hyperthermic intraperitoneal chemotherapy followed by PBC and olaparib maintenance therapy (Group A), 248 underwent SeCRS followed by PBC and olaparib maintenance therapy (Group B), and 135 underwent SeCRS followed by PBC only upon recurrence (Group C). The median progression-free survival for Group A was significantly longer than that for Group B (32.5 vs. 24.2 months, P<0.001), and Group B was significantly longer than Group C (24.2 vs. 15.1 months, P<0.001). The median overall survival for Groups A was significantly longer than that for Group B (71.4 vs. 63.5 months, P<0.001), and Group B was significantly longer than Group C (63.5 vs. 47.5 months, P<0.001). CONCLUSIONS: This study suggested that SeCRS followed by PBC and olaparib maintenance therapy resulted in longer overall survival and progression-free survival than SeCRS followed by PBC only in patients with BRCA mutated recurrent ovarian cancer, especially in patients treated with SeCRS plus hyperthermic intraperitoneal chemotherapy.
