Background Malignant ascites, a complication often seen in patients with ovarian cancer (OC), is difficult to treat, but hyperthermic intraperitoneal chemotherapy (HIPEC) has a good efficacy.
Objective The aim of this study was to assess the efficacy of cytoreductive surgery (CRS) combined with HIPEC for controlling malignant ascites from OC.
Materials and Methods From December 2009 until December 2014, 53 patients with OC and malignant ascites were treated with CRS and HIPEC. Patients in good health condition were treated with CRS followed by HIPEC (CRS + HIPEC), and patients in poor health condition were treated initially with B-mode ultrasound-guided HIPEC followed by delayed CRS upon improvement of their health condition (HIPEC + delayed CRS). Resolution of ascites, complete CRS, overall survival, and disease-free survival were analyzed.
Results All patients showed ascites regression. The total objective remission rate was 100%, even for patients in the poor condition group before CRS. Complete CRS was successful in 30 (88.23%) of 34 patients in the good condition group, and 17 (89.47%) of 19 patients in the poor condition group (P > 0.05). Median disease-free survival and median overall survival were 21 and 39 months in the good condition group, and 22 and 38 months in the poor condition group, respectively (P > 0.05).
Conclusions Hyperthermic intraperitoneal chemotherapy is effective at controlling ascites in patients with OC, even for patients in poor condition before CRS, or when complete CRS is not feasible. Furthermore, the regression of ascites appears not to be dependent on complete resection.
