Exploring global barriers to optimal ovarian cancer care: thematic analysis.

OBJECTIVE: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

Mismatch repair status and surgical approach in apparent early-stage endometrial cancer.

OBJECTIVE: To test the hypothesis that mismatch repair (MMR) status (as an accurate surrogate marker for microsatellite stability) modifies the effect of surgical approach on oncological outcome for apparent early-stage endometrial cancer. METHODS: Observational data from a large prospective population study on endometrial cancer were analyzed using target trial methodology and doubly robust methods, including propensity score matching and adjusted regression analyses. Laparoscopy was compared with laparotomy, stratified by MMR status on outcomes of recurrence and site, and recurrence-free, overall, and disease-specific survival. RESULTS: After matching, there were 400 patients for analysis, with 200 in each treatment group. The mean age was 62 years and mean body mass index was 32 kg/m2. Most patients had early-stage disease (stage I n=362 (90%)) and endometrioid histology (n=363 (91%)). Adjuvant pelvic radiation was administered to 11%, adjuvant vaginal brachytherapy to 13% and adjuvant chemotherapy to 5% of patients. Five-year recurrence-free survival did not differ significantly between modes of surgery across the cohort (p=0.7) or within MMR strata (MMR-proficient p=0.9, MMR-deficient p=0.6). Similarly, there was no significant difference in overall or disease-specific survival by mode of surgery across the cohort or within MMR strata. There was no significant difference in the HR for recurrence for those treated with laparoscopy stratified by MMR status (MMR-proficient HR=0.99 (95% CI 0.28 to 3.58); MMR-deficient HR=0.83 (95% CI 0.24 to 2.87)), even when restricted to endometrioid subtype. CONCLUSION: In this study, there was no evidence of a difference in survival outcomes according to mode of surgery and MMR status.

Exploring international differences in ovarian cancer care: a survey report on global patterns of care, current practices, and barriers.

OBJECTIVE: Although global disparities in survival rates for patients with ovarian cancer have been described, variation in care has not been assessed globally. This study aimed to evaluate global ovarian cancer care and barriers to care. METHODS: A survey was developed by international ovarian cancer specialists and was distributed through networks and organizational partners of the International Gynecologic Cancer Society, the Society of Gynecologic Oncology, and the European Society of Gynecological Oncology. Respondents received questions about care organization. Outcomes were stratified by World Bank Income category and analyzed using descriptive statistics and logistic regressions. RESULTS: A total of 1059 responses were received from 115 countries. Respondents were gynecological cancer surgeons (83%, n=887), obstetricians/gynecologists (8%, n=80), and other specialists (9%, n=92). Income category breakdown was as follows: high-income countries (46%), upper-middle-income countries (29%), and lower-middle/low-income countries (25%). Variation in care organization was observed across income categories. Respondents from lower-middle/low-income countries reported significantly less frequently that extensive resections were routinely performed during cytoreductive surgery. Furthermore, these countries had significantly fewer regional networks, cancer registries, quality registries, and patient advocacy groups. However, there is also scope for improvement in these components in upper-middle/high-income countries. The main barriers to optimal care for the entire group were patient co-morbidities, advanced presentation, and social factors (travel distance, support systems). High-income respondents stated that the main barriers were lack of surgical time/staff and patient preferences. Middle/low-income respondents additionally experienced treatment costs and lack of access to radiology/pathology/genetic services as main barriers. Lack of access to systemic agents was reported by one-third of lower-middle/low-income respondents. CONCLUSIONS: The current survey report highlights global disparities in the organization of ovarian cancer care. The main barriers to optimal care are experienced across all income categories, while additional barriers are specific to income levels. Taking action is crucial to improve global care and strive towards diminishing survival disparities and closing the care gap.

Attributable factors for the rising cesarean delivery rate over 3 decades: an observational cohort study.

BACKGROUND: Cesarean delivery rates continue to rise globally, the reasons for which are incompletely understood. OBJECTIVE: We aimed to characterize the attributable factors for the increasing cesarean delivery rates over a 30-year period within our health network. STUDY DESIGN: This was a planned observational cohort study across 2 hospitals (a large tertiary referral hospital and a metropolitan hospital) in Sydney, Australia using data from a previously published study. The following 2 time periods were compared: 1989-99 and 2009-16, between which the cesarean delivery rate increased from 19% to 30%. The participants were all women who had a cesarean delivery after 24 weeks' gestational age. The data were analyzed using multiple imputation and robust Poisson regression to calculate the differences in the adjusted and unadjusted relative risk of cesarean delivery and estimate the changes in the cesarean delivery rate attributable to maternal and clinical factors. The primary outcome was cesarean delivery. RESULTS: After 576 exclusions, 102,589 births were included in the analysis. Fifty-six percent of the increase in the rate of cesarean delivery was attributed to changes in the distribution of the maternal age, body mass index, and parity and to a history of previous cesarean delivery. An additional 10% of the increase was attributed to changes in the obstetrical management of the following high-risk pregnancies: multiple gestation, malpresentation (mainly breech), and preterm singleton birth. When prelabor cesarean deliveries for maternal choice, suspected fetal compromise, previous pregnancy issues, and suspected large fetus were excluded, 78% of the increase was attributed to either maternal factors or changes in the obstetrical management of these high-risk pregnancies. CONCLUSION: Most of the steep rise in the cesarean delivery rate from 19% to 30% was attributed to changes in the maternal demographic and clinical factors. This observation is relevant to developing preventative strategies that account for nulliparity, age, body mass index, and management of high-risk pregnancies.

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.

BACKGROUND: The 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). AIM: To examine the change in incidence and associated risk factors for a negative LEEP with introduction of primary HPV screening. MATERIALS AND METHODS: A 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. RESULTS: There 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. CONCLUSIONS: Primary 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.

BACKGROUND: Australian 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. AIMS: To 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 METHODS: We 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. RESULTS: We 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. CONCLUSIONS: There 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.

Endometrial adenocarcinoma arising in a pelvic implant following uterine morcellation: A case report.

We report a unique case of a 60-year-old woman developing endometrial cancer in a uterine deposit 18 years after she had undergone laparoscopic subtotal hysterectomy with morcellation for benign pathology. She had used unopposed estrogen as menopausal hormone therapy. She presented with a pelvic mass that was causing pressure symptoms. On imaging, the mass had an enhancing vascular nodular component and appeared to abut normal ovaries and the residual cervix. She proceeded to laparotomy, where a 12 cm pelvic mass was found morbidly adherent to the bladder anteriorly and to the cervical stump. The pelvic mass was excised, and trachelectomy and bilateral salpingo-oophorectomy were performed. Adjacent to this mass was a separate, 5 cm adnexal mass, which was also excised. Histopathology of the smaller pelvic mass was consistent with endometrial adenocarcinoma grade 1, arising in complex endometrial hyperplasia with atypia surrounded by myometrium consistent with a uterine implant. This case highlights the need for consideration and discussion of possible risks of subtotal hysterectomy and morcellation of the uterus for benign disease. Furthermore, given the results in this patient, the use of unopposed estrogen in such patients is discouraged due to possible effects on any residual endometrium still present.

Cesarean delivery: Trend in indications over three decades within a major city hospital network.

INTRODUCTION: The cesarean delivery rate has been increasing globally in recent decades. The reasons for this are complex and subject to ongoing debate. Investigation of the indications for cesarean delivery and how these have changed over an extended period of time could provide insight into the reasons for changing obstetric practice. Our objective was to explore contributing factors to the increasing rate of cesarean delivery by examining the incidence of and indications for cesarean delivery over the past three decades at our institutions. MATERIAL AND METHODS: We conducted a retrospective observational study of all cesarean deliveries, from 24 weeks' gestational age onwards, within an inner-city hospital network in Sydney, Australia, between August 1989 and December 2016. The primary outcome measures were the rates of and indications for emergency and planned cesarean delivery. We also examined our data within the Robson 10-Group Classification system. RESULTS: There were 147 722 births over the study period, with 37 309 cesarean deliveries for an overall rate of 25.3%. The rate of cesarean delivery increased from 18.7% in 1989-1994 (8.7% emergency, 10% planned) to 30.4% in 2010-2016 (11.4% emergency, 19% planned). Emergency cesarean delivery for slow progress increased from 3.4% to 5.5% of all births (a relative increase of 62%) and other emergency cesareans mainly performed for suspected intrapartum fetal compromise increased from 5.2% to 5.6% (a relative increase of 8%). Previous uterine surgery (predominantly cesarean section) was the largest contributor to the increase in planned procedures from 3.8% to 9.0% of all births, and 29% of all cesarean deliveries. Primary cesarean delivery for planned antenatal fetal indications, previous pregnancy problems, multiple gestation and maternal choice all increased substantially in combined rate from 0.7% to 4.9%. Cesarean rates in Robson groups 6, 7 and 8 (term breech and multiple gestations) increased most over time. CONCLUSIONS: The increased rate of cesarean delivery is mainly attributable to a greater number of procedures performed for slow progress in labor, breech presentation or repeat cesarean section.

Intraoperative Frozen Section of Ovarian Tumors: A 6-Year Review of Performance and Potential Pitfalls in an Australian Tertiary Referral Center.

OBJECTIVES: Intraoperative frozen section (IFS) offers a rapid test to guide the extent of surgery, which is essential for optimal treatment of ovarian cancer. This study evaluated the diagnostic performance and influence of IFS in the surgical management of ovarian tumors. METHODS: A retrospective review was conducted of IFS of adnexal lesions from 2008 to 2013, with diagnoses classified as benign, borderline, or malignant. The diagnostic performance of IFS was calculated, with a focus on primary epithelial tumors. In discordant cases, it was determined whether the results of the IFS influenced the nature of the primary surgery. RESULTS: There were 277 consecutive cases over the study period. The overall sensitivity for diagnosing malignant disease was 75.9% and the specificity was 100%. With a benign IFS result, there was a 6.25% (9/144) chance that the final diagnosis would be malignant, and a 7.6% (11/144) chance that the final diagnosis would be borderline, resulting in the potential for understaging. The predictive values for benign, borderline, and malignant IFS results were 86.1%, 66.6%, and 100%, respectively. For a borderline IFS result, there was a 33.3% chance that the final diagnosis would be malignant disease, and this was higher in older patients (53.3%). There were no instances of overdiagnosis in this series. Of 37 cases underdiagnosed, 19 received incomplete primary staging surgery guided by the IFS, and most of these were mucinous tumors. CONCLUSIONS: Intraoperative frozen section is most valuable for its high specificity in diagnosing malignancy. It should be interpreted with caution in borderline tumors, particularly in older patients and in mucinous tumors. Overdiagnosis did not occur in this series; however, in younger patients, the limitations of IFS must be considered before surgery that would result in loss of fertility.

Managing Caesarean Scar Pregnancy in low Resource Settings: 2 Case Reports and a Description of Transrectal Ultrasound guided Surgical Approach (TRUGA).

Caesarean scar pregnancy (CSP) occurs when an embryo implants in a previous caesarean section scar. It has a reported incidence of 1 in 1800. Various surgical and medical techniques have been described in case reports for the management of CSP. These techniques are usually undertaken in tertiary level units with significant resource availability. In this paper, we present a new clinical perspective for the management of CSP in low resource settings and describe the steps involved in a transrectal ultrasound guided approach with dilatation of uterine cervix and subsequent evacuation of uterine contents (TRUGA with D&C).
