Show moreObjectiveTextbook outcome (TO) is a composite outcome measure used in surgical oncology to compare hospital outcomes using multiple quality indicators. This study aimed to develop TO as an outcome measure to assess healthcare quality for patients undergoing cytoreductive surgery (CRS) for advanced-stage ovarian cancer.MethodsThis population-based study included all CRS for FIGO IIIC-IVB primary ovarian cancer registered in the Netherlands between 2017 and 2020. The primary outcome was TO, defined as a complete CRS, combined with the absence of 30-day mortality, severe complications, and prolonged length of admission (≥ten days). Delayed start of adjuvant chemotherapy (≥six weeks) was not included in TO because of missing data. Logistic regressions were used to assess the association of case-mix factors with TO. Hospital variation was displayed using funnel plots.ResultsA total of 1909 CRS were included, of which 1434 were interval CRS and 475 were primary CRS. TO was achieved in 54% of the interval CRS cohort and 47% of the primary CRS cohort. Macroscopic residual disease after CRS was the most important factor for not achieving TO. Age ≥ 70 was associated with lower TO rates in multivariable logistic regressions. TO rates ranged from 40% to 69% between hospitals in the interval CRS cohort and 22% to 100% in the primary CRS cohort. In both analyses, one hospital had significantly lower TO rates (different hospitals). Case-mix adjustment significantly affected TO rates in the primary CRS analysis.ConclusionsTO is a suitable composite outcome measure to detect hospital variation in healthcare quality for patients with advanced-stage ovarian cancer undergoing CRS. Case-mix adjustment improves the accuracy of the hospital comparison. Show less

Show moreBackgroundThe most important goal for survival benefit of advanced stage ovarian cancer is to surgically remove all visible tumour, because complete cytoreductive surgery (CCS) has been shown to be associated with prolonged survival.In a remarkable number of women, CCS is very challenging. Especially in women with many small metastases on the peritoneum and intestinal surface, conventional CCS with electrosurgery is not able to be complete in removing safely all visible tumour.In this randomized controlled trail (RCT) we investigate whether the use of the PlasmaJet Surgical Device increases the rate of CCS, and whether this indeed leads to a longer progression free and overall survival.The main research question is: does the use of the PlasmaJet Surgical Device in surgery for advanced stage ovarian cancer result in an increased number of complete cytoreductive surgeries when compared with conventional surgical techniques. Secondary study objectives are: 30-day morbidity, duration of surgery, blood loss, length of hospitalisation, Quality of Life, disease-free survival, overall survival, percentage colostomy, cost-effectiveness.MethodsThe study design is a multicentre single-blinded superiority RCT in two university and nine non-university hospitals in The Netherlands. Three hundred and thirty women undergoing cytoreductive surgery for advanced stage ovarian carcinoma (FIGO Stage IIIB-IV) will be randomized into two arms: use of the PlasmaJet (intervention group) versus the use of standard surgical instruments combined with electrocoagulation (control group). The primary outcome is the rate of complete cytoreductive surgery in both groups.Secondary study objectives are: 30-day morbidity, duration of surgery, blood loss, length of hospitalisation, Quality of Life, disease-free survival, overall survival, percentage colostomy, cost-effectiveness. Quality of life will be evaluated using validated questionnaires at baseline, at 1 and 6months after surgery and at 1, 2, 3 and 4years after surgery.DiscussionWe hypothesize the additional value of the use of the PlasmaJet in CCS for advanced stage epithelial ovarian cancer. More knowledge about efficacy, side effects, recurrence rates, cost effectiveness and pathology findings after using the PlasmaJet Device is advocated. This RCT may aid in this void.Trial registrationDutch Trial Register NTR6624.
