Exploring global barriers to optimal ovarian cancer care: thematic analysis

To explore the barriers to ovarian cancer care, as reported in the open ended responses of a global expert opinion survey, highlighting areas for improvement in global ovarian cancer care. Potential solutions to overcome these barriers are proposed. Data from the expert opinion survey, designed to assess the organization of ovarian cancer care worldwide, were analyzed. The survey was distributed across a global network of physicians. We examined free text, open ended responses concerning the barriers to ovarian cancer care. A qualitative thematic analysis was conducted to identify, analyze, and report meaningful patterns within the data. A total of 1059 physicians from 115 countries completed the survey, with 438 physicians from 93 countries commenting on the barriers to ovarian cancer care. Thematic analysis gave five major themes, regardless of income category or location: societal factors, inadequate resources in hospital, economic barriers, organization of the specialty, and need for early detection. Suggested solutions include accessible resource stratified guidelines, multidisciplinary teamwork, public education, and development of gynecological oncology training pathways internationally. This analysis provides an international perspective on the main barriers to optimal ovarian cancer care. The themes derived from our analysis highlight key target areas to focus efforts to reduce inequalities in global care. Future regional analysis involving local representatives will enable country specific recommendations to improve the quality of care and ultimately to work towards closing the care gap.

The impact of primary human papillomavirus screening on negative loop excision histology following biopsy‐proven high‐grade cervical intra‐epithelial lesions: A review from a large tertiary colposcopy unit

BackgroundThe renewed National Cervical Screening Program incorporating primary human papillomavirus (HPV) screening was implemented in Australia in December 2017. In a previous study conducted in the UK, primary HPV screening was found to be associated with a 25% reduction in the incidence of negative histology following loop electrosurgery excision procedure (LEEP).AimTo examine the change in incidence and associated risk factors for a negative LEEP with introduction of primary HPV screening.Materials and MethodsA retrospective review of the records of all patients undergoing a LEEP excision for biopsy‐proven high‐grade cervical intra‐epithelial lesions between 1 January 2014 and 30 June 2019 in a specialised centre.ResultsThere were 1123 patients who underwent a LEEP included in the analysis. The incidence of a negative LEEP specimen was 7.5% (59/784) and 5.3% (18/339) in the pre‐ and post‐HPV screening cohort. More patients in the post‐HPV screening group had low‐grade cytology on referral (P < 0.001), smaller cervical lesions on colposcopy (P = 0.012) and longer biopsy to treatment interval (P = 0.020). Primary HPV screening was associated with a significant reduction in the incidence of a negative LEEP specimen in a propensity matched cohort (11.2% to 5.1%, P = 0.006) and a 41% (P = 0.045) decreased relative risk of a negative LEEP on multivariate analysis.ConclusionsPrimary HPV screening results in a lower incidence of negative LEEP histology, despite a longer biopsy to treatment wait time and higher proportion of low‐grade cytology at triage.

Follow‐up after treatment of high‐grade cervical dysplasia: The utility of six‐month colposcopy and cytology and routine 12‐month colposcopy

BackgroundAustralian Cervical Screening Program guidelines no longer recommend colposcopy and cytology at six months following treatment of cervical intraepithelial neoplasia (CIN2/3) and a co‐test of cure can be performed at 12 months without colposcopy.AimsTo determine the usefulness of six‐month colposcopy and cytology and routine colposcopy with co‐testing at 12 months in detecting persistent or recurrent disease in patients treated for CIN2/3.Materials and MethodsWe conducted a review of all patients with histologically proven CIN2/3 who underwent a cervical excisional procedure between March 2012 and March 2017 in one specialised centre.ResultsWe examined 1215 cases and 750 remained after exclusions for analysis. At six months (722 cases, 96.2%) seven of 42 (16.7%) patients with high‐grade cytology had a high‐grade colposcopy and 24 of 42 (57.1%) had a normal colposcopy. Persistent CIN2/3 was diagnosed in 12 cases (1.7%) and only 1/3 had a high‐grade colposcopy. Cytology was more useful than colposcopy in detecting persistent disease. At 12 months (638 cases, 85%) routine colposcopy at the time of co‐testing had a high false positive rate with all high‐grade changes negative on biopsy and co‐test. Recurrent CIN2/3 was diagnosed in five cases, and four had normal colposcopy at co‐testing.ConclusionsThere may be a delay in detection of persistent/recurrent CIN2/3 in a small number of cases without six‐month colposcopy and cytology; however, it is not likely to negatively impact overall clinical outcome. Co‐testing at 12 months following treatment of CIN2/3 without colposcopy is safe and routine colposcopy at collection of the co‐test can be omitted.
