Abstract

PURPOSE: Adjuvant use of Neutral Argon Plasma (PlasmaJet Surgical Device) during cytoreductive surgery (CRS) for advanced-stage epithelial ovarian cancer improves surgical outcomes. The aim of this study is to examine the costs of adjuvant use of the PlasmaJet during surgery compared with conventional CRS in advanced-stage epithelial ovarian cancer. MATERIALS AND METHODS: The patients were randomly assigned to surgery with or without the PlasmaJet. Analysis of the intra- and extramural health care costs was performed. Costs were divided into three categories: costs of the diagnostic phase (T1), inpatient care up to discharge including costs of surgery (T2), and outpatient care including chemotherapy until 6 weeks after the last cycle of chemotherapy (T3). RESULTS: Overall, 327 patients underwent CRS (surgery with PlasmaJet: n = 157; conventional surgery: n = 170). The mean total health costs were significantly higher for CRS with adjuvant use of PlasmaJet compared with conventional CRS (€19,414 v €18,165, P = .017). Costs are divided into costs of the diagnostic phase (€2,034 v €1,974, P = .890), costs of inpatient care (€10,956 v €9,556, P = .003), and costs of outpatient care (€6,417 v €6,628, P = .147). CONCLUSION: Mean total health care costs of the use of PlasmaJet in CRS were significantly higher than those for conventional CRS. This difference is fully explained by the additional surgery costs of the use of PlasmaJet. However, surgery with the use of the PlasmaJet leads to a significantly higher percentage of complete CRS and a halving of stomas. A cost-effectiveness analysis will be performed once survival data are available (funded by ZonMw, Trial Register NL62035.078.17).
