Statement by the Kommission OVAR of the AGO Study Group on the Use of HIPEC (Hyperthermic Intraperitoneal Chemotherapy) to Treat Primary and Recurrent Ovarian Cancer.

ABSTRACT: HIPEC is offered to patients with ovarian, fallopian tube or primary peritoneal cancer at some hospitals. Altogether, there is still no evidence that HIPEC leads to an improvement of prognosis in any gynecologic tumor, neither in primary therapy nor in treatment of relapse. The available data indicate an increased complication rate which might negatively impact the benefit-risk balance of this procedure. In addition, standard treatment with proven efficacy might be withheld due to application of unproven methods. The use of HIPEC outside of well designed, prospective and controlled clinical trials is therefore disregarded.

Project description:IntroductionOvarian cancer is the most lethal gynecologic malignancy. Although treatment with hyperthermic intraperitoneal chemotherapy (HIPEC) has shown promising results, its role remains elusive. The aim of this study was to assess the comprehensive randomized evidence for the use versus non-use of HIPEC in primary and recurrent ovarian cancer.Materials and methodsThe Medline, Embase and Cochrane databases, as well as the European Society for Medical Oncology (ESMO) and American Society of Clinical Oncology (ASCO) conference abstracts of the last 5 years, were scrutinized in January 2022 for randomized, controlled trials that studied the use of HIPEC in ovarian cancer. Overall survival (OS), disease-free survival (DFS) and progression-free survival, as well as post-operative morbidity were the outcomes of interest. This study was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guideline.ResultsSix randomized, controlled trials that randomized 737 patients were included in our analysis; of these, four studies (519 patients) were in primary and two (218 patients) in recurrent settings. In primary ovarian cancer, the combination of HIPEC with interval cytoreductive surgery (CRS) and neoadjuvant chemotherapy significantly improved the 5-year OS [393 patients, risk ratio (RR) = 0.77; 95% confidence interval (CI) 0.67-0.90; P value = 0.001] and DFS (hazard ratio = 0.60; 95% CI 0.41-0.87; P value = 0.008) compared with standard treatment alone. In the absence of neoadjuvant chemotherapy, the use of HIPEC + CRS was not associated with any survival advantage (126 patients, 4-year OS, RR = 0.93; 95% CI 0.57-1.53; P value = 0.781), but the sample size was smaller in this subset. Use of HIPEC in recurrent ovarian cancer did not provide any survival advantage (5-year OS: 218 patients, RR = 0.85; 95% CI 0.45-1.62; P value = 0.626). The risk for grade ≥3 adverse events was similar between HIPEC and no HIPEC (RR = 1.08; 95% CI 0.98-1.18; P value = 0.109).ConclusionsIn primary ovarian cancer the combination of HIPEC with interval CRS and neoadjuvant chemotherapy is a safe option that significantly improved 5-year OS and DFS. Its use in other settings should continue to be considered investigational.
