Background: Hyperthermic intraperitoneal chemotherapy (HIPEC) in combination with interval cytoreductive surgery increases the overall survival of epithelial ovarian cancer (EOC) patients with advanced disease. Despite its proven benefits, the mechanism by which HIPEC extends overall survival remains unknown and current strategies to optimize HIPEC are therefore limited. A major challenge is the lack of a robust and streamlined model to investigate the mechanisms underlying HIPEC efficacy. Objective: To introduce a novel murine model that can be used to enhance our understanding of HIPEC therapy. Method: ID8-luc, an EOC mouse cell line, is inoculated into immunocompetent C57BL/6J mice intraperitoneally. Once tumor is detected by In Vivo Imaging System (IVIS), cisplatin (5 mg/kg) is injected intraperitoneally and superficial hyperthermia of 40C is applied to the animals abdomen and pelvis using an FDA-approved hyperthermia unit (BSD500) for 20 minutes. To validate the model, four treatment conditions were tested: cisplatin and hyperthermia, cisplatin and normothermia, vehicle and hyperthermia, and vehicle and normothermia. Tumor growth was assessed over the course of treatment using IVIS optical spectrum. Results: Tumor growth in mice treated with hyperthermic cisplatin was significantly suppressed compared to mice treated with normothermic cisplatin (p < 0.05). No significant differences in tumor growth were observed in the hyperthermic vehicle and normothermic vehicle groups. Conclusions: We developed an innovative noninvasive mouse model of HIPEC. Similar to patients with advanced ovarian cancer who are treated with HIPEC at the time of interval cytoreductive surgery, our model demonstrates that hyperthermia enhances the inhibitory effect of cisplatin on intraperitoneal tumor growth. Development of this murine model provides an opportunity to elucidate the mechanisms underlying HIPEC and offer an opportunity to test adjunct treatments in a pre-clinical setting to enhance the utility of HIPEC.

The first experience of cytoreductive surgery technology and intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC) usage in the practice of Irkutsk Regional Cancer Center. All subjects were divided into 2 groups: the group of clinical comparison - the patients after suboptimal cytoreduction (53 persons), and the main group - the patients after optimal or complete debulking operation and hyperthermic intraperitoneal chemotherapy in some cases (32 persons). The subjects had ovarian cancer. The indispensable prerequisite of picking was confirmed carcinomatous peritoneal spread, resectable process, overall status. The primary analysis assay included time factors such as preoperation period, operation time, postoperative bed-days, in plus, complications and their character in postoperative period. In the article there are statistics of disease-free and overall survival in all groups and full consistent outline of the intraoperative hyperthermic chemotherapy method. The research has prospective character, observation continued. Expected results will be significant difference of disease-free and overall survival in the groups of interest.

BackgroundThe addition of hyperthermic intraperitoneal chemotherapy (HIPEC) to interval cytoreductive surgery improves recurrence-free and overall survival in patients with FIGO stage III ovarian cancer who are ineligible for primary cytoreductive surgery. The effect of HIPEC remains undetermined in patients who are candidates for primary cytoreductive surgery.Primary objectiveThe primary objective is to evaluate the effect of HIPEC on overall survival in patients with FIGO stage III epithelial ovarian cancer who are treated with primary cytoreductive surgery resulting in no residual disease, or residual disease up to 2.5 mm in maximum dimension.Study hypothesisWe hypothesize that the addition of HIPEC to primary cytoreductive surgery improves overall survival in patients with primary FIGO stage III epithelial ovarian cancer.Trial designThis international, randomized, open-label, phase III trial will enroll 538 patients with newly diagnosed FIGO stage III epithelial ovarian cancer. Following complete or near-complete (residual disease ≤2.5 mm) primary cytoreduction, patients are randomly allocated (1:1) to receive HIPEC or no HIPEC. All patients will receive six courses of platinum-paclitaxel chemotherapy, and maintenance PARP-inhibitor or bevacizumab according to current guidelines.Major eligibility criteriaPatients with FIGO stage III primary epithelial ovarian, fallopian tube, or primary peritoneal cancer are eligible after complete or near-complete primary cytoreductive surgery. Patients with resectable umbilical, spleen, or local bowel lesions may be included. Enlarged extra-abdominal lymph nodes should be negative on FDG-PET or fine-needle aspiration/biopsy.Primary endpointThe primary endpoint is overall survival.Sample sizeTo detect a HR of 0.67 in favor of HIPEC, 200 overall survival events are required. With an expected accrual period of 60 months and 12 months additional follow-up, 538 patients need to be randomized.Estimated dates for completing accrual and presenting resultsThe OVHIPEC-2 trial started in January 2020 and primary analyses are anticipated in 2026.Trial registrationClinicalTrials.gov:NCT03772028
