Abstract
Purpose
Hyperthermic intraperitoneal chemotherapy (HIPEC) potentially confers significant survival benefits in the management of ovarian cancer although the long-term data remain scant. We sought to compare the survival rates of advanced stage ovarian cancer patients who were treated with primary induction therapy alone or in conjunction with consolidation HIPEC.
Methods
69 ovarian cancer patients who underwent surgery and completed their primary induction chemotherapy were treated with consolidation carboplatin (AUC 10) based HIPEC and compared to a historical cohort that received surgery and primary chemotherapy alone (n = 69). The demographic and clinical characteristics on which we were primarily focused, included patient age, body mass index, surgery and pathology data, chemotherapy regimen, toxicity, and progression free/overall survival.
Results
The two patient groups' demographic and clinical characteristics were similar (P > 0.05). Progression-free survival was significantly more pronounced in the HIPEC (25.1 months) patients compared to the control group (20 months) (P = 0.024) and there was a decreased risk of disease progression accorded to the patients treated with HIPEC (HR 2.1028; 95% CI 1.2941–3.4167; P = 0.0027). However, we did not discern any HIPEC related overall survival advantages (P = 0.29).
Conclusions
The results from our ovarian cancer study suggest that adjunctive HIPEC proffers a significant progression-free survival advantage and a decreased risk for disease progression. There was, however, no overall survival advantage discerned by the HIPEC group. We also recognize that HIPEC remains controversial, and thus randomized studies evaluating HIPEC compared to standard chemotherapy in the management of ovarian cancer are warranted.
