Abstract
Background
Ovarian cancer has the highest mortality among gynecologic malignancies. Despite cytoreductive surgery (CRS) and systemic therapy, peritoneal recurrence remains common. Hyperthermic intraperitoneal chemotherapy (HIPEC) delivers heated chemotherapy directly to the peritoneal cavity, enhancing local cytotoxicity and offering a potential therapeutic strategy.
Methods
We searched PubMed, Embase, and Cochrane for randomized controlled trials (RCTs) comparing CRS plus HIPEC versus CRS alone. Hazard ratios (HR), odds ratios (OR), and mean differences (MD) were pooled using Review Manager 5.4. Heterogeneity was assessed using I2 statistics. Primary outcomes were overall survival (OS) and progression-free survival (PFS); secondary outcomes included operative time, Grade 3–5 adverse events, time to adjuvant chemotherapy, and hospital length of stay (LOS). Subgroup analyses were performed for primary vs. recurrent cancer, neoadjuvant chemotherapy (NACT) vs. no NACT, HIPEC duration (60 vs. 90 min), and high-grade serous vs. other histologies.
Results
Eight RCTs (1259 patients) were included; 636 (50.52%) received CRS with HIPEC. HIPEC significantly improved OS (HR 0.79; 95% CI 0.67–0.94; p = 0.006; I2 = 9%), especially in primary ovarian cancer (HR 0.75; 95% CI 0.60–0.94; p = 0.01; I2 = 0%). No OS benefit was observed in recurrent disease (HR 0.87; 95% CI 0.63–1.19; p = 0.38; I2 = 39%). PFS showed no overall difference (HR 0.86; p = 0.30). HIPEC increased operative time (MD 127.75 min; p < 0.00001), LOS (MD 1.49 days; p = 0.03), and Grade 3–5 adverse events (OR 1.50; p = 0.03).
Conclusions
In ovarian cancer, HIPEC significantly improved OS, especially in primary disease and following NACT. However, increased morbidity was observed. Further studies should refine patient selection and optimize protocols.
