A1 García Sabrido, José Luis AB AimCytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (CRS + HIPEC) has been proposed as treatment for advanced epithelial ovarian carcinoma (EOC). No consensus exists on when to administer CRS + HIPEC during the natural history of the disease, namely, as upfront therapy, at first recurrence, or at second or subsequent recurrence.Patients and methodsWe analyzed a series of patients with advanced EOC collected prospectively in an institution with a peritoneal malignant disease treatment program. Patients were treated with CRS + HIPEC upfront, at first recurrence, and at second or subsequent recurrence.ResultsWe treated 42 patients: 15 upfront, 19 at first recurrence, and 8 at second or subsequent recurrence. Cytoreduction was complete (CC0) in 75% of cases; residual disease was <2.5 mm (CC1) in 25%. Severe morbidity (CTCAE v.3.0, grade 3–4) was 26%, and hospital mortality was 7%. After a median follow-up of 24 months, median overall survival was 77.8 months for patients treated upfront, 62.8 months for patients treated at first recurrence, and 35.7 months for patients treated at second or subsequent recurrence. Disease-free survival was 21.1 months, 18 months, and 5.7 months, respectively. Overall survival in the upfront and first recurrence groups was similar, and statistically significant differences with the second recurrence group were identified (p < 0.03).ConclusionsTreatment of advanced EOC using CRS + HIPEC is promising in terms of overall survival and disease-free survival when administered as upfront and at first recurrence therapy. These results warrant further evaluation in a randomized trial.
