INTRODUCTION: Hyperthermic intraperitoneal chemotherapy (HIPEC) is increasingly being used in patients with stage III ovarian cancer undergoing interval cytoreductive surgery (CRS). It is uncertain whether routine postoperative admission to a critical care setting after CRS-HIPEC is necessary. This study aims to estimate the incidence of patients requiring critical care, and to create a prediction model to identify patients who may forego admission to a critical care setting. METHODS: We analyzed 154 patients with primary ovarian cancer undergoing interval CRS-HIPEC at two Dutch centers between 2007 and 2021. Patients were routinely admitted to a critical care setting for 12-24 h. Patients that received critical support as defined by pre-specified definitions were retrospectively identified. Logistic regression analysis with backward selection was used to predict the need for critical care and the model was validated using bootstrapping. RESULTS: Thirty-eight percent of patients received postoperative critical care, consisting mainly of hemodynamic interventions. Independent predictors of critical care were blood loss, norepinephrine dose during surgery, and age (bootstrapped AUC = 0.76). Using a probability cut-off of 20%, one-third of patients are defined as low-risk for requiring critical care, with a negative predictive value of 0.88. CONCLUSIONS: The majority of patients,primarily undergoing low to intermediate complexity surgeries, did not receive critical care interventions after CRS-HIPEC. Selective admission to a critical care setting may be warranted and its feasibility and safety needs to be evaluated prospectively. Our prediction model can help identify patients in whom admission to a critical care setting may be omitted. Hospital costs and burden on critical care units will benefit from patient selection.

OBJECTIVE: The OVHIPEC-1 trial (Phase III randomised clinical trial for stage III ovarian carcinoma randomising between interval cytoreductive surgery with or without hyperthermic intraperitoneal chemotherapy) showed improved survival when interval cytoreductive surgery (CRS) was combined with hyperthermic intraperitoneal chemotherapy in patients with stage III epithelial ovarian cancer (EOC). The authors compared the control arm of the trial with a real-world population treated in the Netherlands during the same period to explore generalizability of the trial results. METHODS: For this nationwide comparative cohort study, all patients with EOC undergoing interval CRS between 2007 and 2016 were identified from the Netherlands Cancer Registry if they fulfilled the eligibility criteria of OVHIPEC-1 (n = 1376). Patient and treatment characteristics, and overall survival (OS) were compared between trial and real-world populations. RESULTS: Age, comorbidity, BRCA status, histologic subtype, and residual disease were similar in trial and real-world patients. Trial patients had a better performance status, higher socioeconomic status, and underwent bowel surgery more often. In a real-world setting, patients more often received more than six cycles. The difference in OS between the trial and the real-world populations was not statistically significant (unadjusted hazard ratio, 1.09 [95% confidence interval, 0.87-1.37]; P = 0.44). CONCLUSION: Despite differences in patient characteristics, OS of patients treated in the control arm of OVHIPEC-1 was similar to patients treated outside the trial. The trial population accurately represents real-world patients with stage III EOC undergoing interval CRS in terms of outcome.

BACKGROUND: The value of hyperthermic intraperitoneal chemotherapy (HIPEC) at the time of cytoreductive surgery (CRS) for epithelial ovarian cancer (EOC) is controversial and its use remains experimental in most national and international guidelines. We wished to systematically evaluate all available evidence. METHODS: A comprehensive review of data from MEDLINE, EMBASE, and Cochrane Library databases was conducted from the first report on HIPEC in EOC till April 3, 2022. Progression-free survival (PFS) and overall survival (OS) were compared between the HIPEC and control groups. This meta-analysis was registered with PROSPERO (CRD42021265810). RESULTS: Fifteen studies (10 case-control studies and 5 randomized controlled trials [RCTs]) were included in the present meta-analysis. Based on the time interval between the last systemic chemotherapy exposure and timing of CRS +/- HIPEC, all studies and patients' cohorts we classified into recent (<6 months; n = 9 studies/patients cohorts) and non-recent (≥6 months, n = 8 studies/patients cohorts) chemotherapy exposure groups. In the recent chemotherapy exposure group, HIPEC was associated with improvement of both PFS (HR, 0.585; 95% CI, 0.422-0.811) and OS (HR, 0.519; 95% CI, 0.346-0.777). On the contrary, in the non-recent chemotherapy exposure group, HIPEC failed to significantly affect PFS (HR, 1.037; 95% CI, 0.684-1.571) or OS (HR, 0.932; 95% CI, 0.607-1.430). Consistent results were observed in subsequent sensitivity analyses. CONCLUSION: Our present meta-analysis demonstrates that the value of HIPEC at CRS for EOC appears to depend on the timing of the last systemic chemotherapy exposure. Future trials are awaited to define the role of HIPEC in EOC.

The long-term survival of advanced-stage ovarian cancer patients remains poor, despite extensive cytoreductive surgery, chemotherapy, and the recent addition of poly (ADP-ribose) polymerase inhibitors (PARPi). Hyperthermic intraperitoneal chemotherapy (HIPEC) has shown survival benefit by specifically targeting peritoneal metastases, the primary site of disease recurrence. Different aspects of how HIPEC exerts its effect remain poorly understood. Improved understanding of the effects of hyperthermia on ovarian cancer cells, the synergy of hyperthermia with intraperitoneal chemotherapy, and the pharmacological and pharmacokinetic properties of intraperitoneally administered cisplatin may help identify ways to optimize the efficacy of HIPEC. This review provides an overview of these translational and pharmacological principles of HIPEC and aims to expose knowledge gaps that may direct further research to optimize the HIPEC procedure and ultimately improve survival for women with advanced ovarian cancer.

Patients with advanced epithelial ovarian cancer have a high incidence of peritoneal disease recurrence despite maximal efforts to surgically remove all visible tumor plus intravenous chemotherapy. The administration of intraperitoneal chemotherapy that specifically targets the peritoneal surface has been investigated in previous trials, but questions about the design of these studies has prevented this treatment from being widely adopted in clinical practice. Hyperthermic intraperitoneal chemotherapy (HIPEC) is a single intraoperative approach that also targets the peritoneal surface. A randomized phase 3 trial showed significant benefit in recurrence-free and overall survival when HIPEC was added to interval cytoreductive surgery (CRS) in patients who were not eligible for primary surgery because of the extent of their disease (OVHIPEC trial; NCT00426257). The trial showed no important differences in toxicity or patient-reported outcomes between the study groups. The extent of surgery and the number of bowel resections were also similar between the 2 study groups, and the effect of HIPEC was homogeneous across the levels of predefined and post hoc subgroups. Nevertheless, the design and the results of the OVHIPEC trial were critically assessed, and this resembles the reluctance to adopt the positive results of the earlier intraperitoneal chemotherapy studies. This overview discusses the design and results of the OVHIPEC trial. The evidence that is currently available points to a clinically relevant and cost-effective benefit of HIPEC added to interval CRS for patients with stage III ovarian cancer who are not eligible for primary surgery. Ongoing collaborative research will provide further evidence regarding the role of HIPEC in ovarian cancer.

BACKGROUND: Treatment of newly diagnosed advanced-stage ovarian cancer typically involves cytoreductive surgery and systemic chemotherapy. We conducted a trial to investigate whether the addition of hyperthermic intraperitoneal chemotherapy (HIPEC) to interval cytoreductive surgery would improve outcomes among patients who were receiving neoadjuvant chemotherapy for stage III epithelial ovarian cancer. METHODS: In a multicenter, open-label, phase 3 trial, we randomly assigned 245 patients who had at least stable disease after three cycles of carboplatin (area under the curve of 5 to 6 mg per milliliter per minute) and paclitaxel (175 mg per square meter of body-surface area) to undergo interval cytoreductive surgery either with or without administration of HIPEC with cisplatin (100 mg per square meter). Randomization was performed at the time of surgery in cases in which surgery that would result in no visible disease (complete cytoreduction) or surgery after which one or more residual tumors measuring 10 mm or less in diameter remain (optimal cytoreduction) was deemed to be feasible. Three additional cycles of carboplatin and paclitaxel were administered postoperatively. The primary end point was recurrence-free survival. Overall survival and the side-effect profile were key secondary end points. RESULTS: In the intention-to-treat analysis, events of disease recurrence or death occurred in 110 of the 123 patients (89%) who underwent cytoreductive surgery without HIPEC (surgery group) and in 99 of the 122 patients (81%) who underwent cytoreductive surgery with HIPEC (surgery-plus-HIPEC group) (hazard ratio for disease recurrence or death, 0.66; 95% confidence interval [CI], 0.50 to 0.87; P=0.003). The median recurrence-free survival was 10.7 months in the surgery group and 14.2 months in the surgery-plus-HIPEC group. At a median follow-up of 4.7 years, 76 patients (62%) in the surgery group and 61 patients (50%) in the surgery-plus-HIPEC group had died (hazard ratio, 0.67; 95% CI, 0.48 to 0.94; P=0.02). The median overall survival was 33.9 months in the surgery group and 45.7 months in the surgery-plus-HIPEC group. The percentage of patients who had adverse events of grade 3 or 4 was similar in the two groups (25% in the surgery group and 27% in the surgery-plus-HIPEC group, P=0.76). CONCLUSIONS: Among patients with stage III epithelial ovarian cancer, the addition of HIPEC to interval cytoreductive surgery resulted in longer recurrence-free survival and overall survival than surgery alone and did not result in higher rates of side effects.

BACKGROUND: Improvement in treatment for patients with recurrent ovarian cancer is needed. Standard therapy in patients with platinum-sensitive recurrent ovarian cancer consists of platinum-based chemotherapy. Median overall survival is reported between 18 and 35 months. Currently, the role of surgery in recurrent ovarian cancer is not clear. In selective patients a survival benefit up to 62 months is reported for patients undergoing complete secondary cytoreductive surgery. Whether cytoreductive surgery in recurrent platinum-sensitive ovarian cancer is beneficial remains questionable due to the lack of level I-II evidence. METHODS/DESIGN: Multicentre randomized controlled trial, including all nine gynecologic oncologic centres in the Netherlands and their affiliated hospitals. Eligible patients are women, with first recurrence of FIGO stage Ic-IV platinum-sensitive epithelial ovarian cancer, primary peritoneal cancer or fallopian tube cancer, who meet the inclusion criteria. Participants are randomized between the standard treatment consisting of at least six cycles of intravenous platinum based chemotherapy and the experimental treatment which consists of secondary cytoreductive surgery followed by at least six cycles of intravenous platinum based chemotherapy. Primary outcome measure is progression free survival. In total 230 patients will be randomized. Data will be analysed according to intention to treat. DISCUSSION: Where the role of cytoreductive surgery is widely accepted in the initial treatment of ovarian cancer, its value in recurrent platinum-sensitive epithelial ovarian cancer has not been established so far. A better understanding of the benefits and patients selection criteria for secondary cytoreductive surgery has to be obtained. Therefore the 4th ovarian cancer consensus conference in 2010 stated that randomized controlled phase 3 trials evaluating the role of surgery in platinum-sensitive recurrent epithelial ovarian cancer are urgently needed. We present a recently started multicentre randomized controlled trial that will investigate the role of secondary cytoreductive surgery followed by chemotherapy will improve progression free survival in selected patients with first recurrence of platinum-sensitive epithelial ovarian cancer.
