Key clinical findings from the IMPROVE-UK quality improvement projects: an overview

Introduction Survival from ovarian cancer in the UK is poor compared with international comparators. The Ovarian Cancer Audit Feasibility Pilot demonstrated variation in 1-year and 5-year survival across the UK as well as significant variation in treatment rates. In 2020, IMPROVE-UK was established as the first major programme to address inequalities in ovarian cancer management and survival across the UK, to develop a legacy of best practice sharing across the country and to establish and evaluate quality improvement projects that could drive care at scale. Methods Following a competitive process, seven quality improvement projects were funded to address inequalities in care and identify strategies to improve and equalise survival rates for all women with ovarian cancer in the UK, to address health inequalities from geography, age or ethnicity. Results Projects addressed the secondary care diagnostic pathway, genomic testing, prehabilitation and improving treatment-related decision-making, particularly decisions for surgery. All seven projects at least partial achieved their aims with numerous areas across all projects identified where processes could be refined and incorporated into standard care to improve outcomes of women diagnosed with ovarian cancer. Dissemination of information regarding best practice has been undertaken. Conclusion IMPROVE-UK was the first programme of its kind addressing significant inequalities of care in women with ovarian cancer. We demonstrate systematic quality improvement projects in ovarian cancer targeting various aspects of the treatment journey. Scaling up the results of the improve UK pilots is likely to improve survival in the UK and potentially internationally.

Neo-adjuvant chemotherapy does not reduce surgical complexity nor the accuracy of intra-operative visual assessment of disease in advanced ovarian cancer

Compare the surgical complexity and histological accuracy of visual inspection of disease in patients undergoing primary debulking (PDS) versus delayed debulking surgery (DDS) following neo-adjuvant chemotherapy (NACT) for advanced ovarian cancer (AOC). All patients undergoing PDS or DDS for stage III / IV AOC at a UK cancer centre between January 2014-October 2021 were included. Retrospective data was collected accessing an electronic gynaecological oncology database, operation and histology records. Comparative frequencies of surgical procedures performed were calculated for primary versus delayed cohorts; and correlation between intra-operative suspicion of disease and specimen histology at PDS and DDS compared. N=232. PDS was performed in 45.3% and DDS in 54.7% of patients; achieving complete cytoreduction in 77.2%. Appendicectomy, pelvic and para-aortic nodal dissection were undertaken significantly more often at primary surgery; whilst right diaphragm stripping, pelvic peritonectomy, splenectomy and cholecystectomy were more likely following NACT. We found no variation in bowel resection rates between cohorts. For the majority of specimens, there was no difference in correlation between intra-operative suspicion of disease and final histopathology - with a significantly lower positive predictive value for visual assessment demonstrated only for liver capsule and pelvic peritoneum at DDS. NACT does not appear to reduce the complexity of surgery, including rates of bowel resection; nor accuracy of intra-operative visual assessment of disease. We therefore caution against both deferring to NACT to facilitate less radical delayed debulking; and any presumption that macroscopically abnormal tissue at DDS may represent inert post-NACT 'burn-out', mitigating indication for excision. We instead suggest reservation of the neo-adjuvant pathway for patients with poor PS and radiologically-confirmed surgical stopping points; and advocate equivalent and maximal cytoreductive effort to remove all visibly abnormal tissue in both the upfront and delayed surgical settings.

Poor anaerobic threshold and VO2 max recorded during cardiopulmonary exercise testing (CPET) prior to cytoreductive surgery in advanced (stage 3/4) ovarian cancer (AOC) is associated with suboptimal cytoreduction but does not preclude maximum effort cytoreduction

This study assessed Cardiopulmonary Exercise Testing (CPET) in predicting oncological outcomes, post-operative recovery and complications in advanced ovarian cancer (AOC) cytoreductive surgery. We reviewed all patients who had CPET prior to AOC cytoreductive surgery with evidence of upper abdominal disease on preoperative imaging at the University Hospitals of Derby and Burton (UHDB) between August 2016 and July 2019. Patients were stratified by AT and maximum VO
