RESUMEN
OBJECTIVES: Opportunistic salpingectomy (OS) is the removal of fallopian tubes during another pelvic surgery for the purpose of ovarian cancer prevention. Herein, we describe the rates of OS at the time of hysterectomy and tubal sterilization between 2017 and 2020. METHODS: This study uses the Canadian Institute of Health Information's Discharge Abstract Database and National Ambulatory Care Reporting System for all Canadian provinces and territories except for Quebec between the fiscal years 2017 and 2020. A descriptive analysis on all people aged 15 years and older who had hysterectomies or tubal sterilizations was conducted to determine the proportion of hysterectomies that included bilateral salpingectomy (OS) and the proportion of tubal sterilizations that were OS compared to tubal ligation. RESULTS: There were 174 006 people included in the study. The proportion of hysterectomies that included OS increased from 31.7% in 2017 to 39.9% by 2020. With respect to tubal sterilizations, rates of OS increased from 26.3% of all tubal sterilizations in 2017 to 42.5% in 2020. British Columbia remained the jurisdiction with the highest rates of OS, but rates increased significantly in many jurisdictions, particularly at the time of tubal sterilization. CONCLUSION: The rates of OS have continued to increase in all Canadian jurisdictions following the official Society of Obstetricians and Gynaecologists of Canada recommendation to consider OS in 2015. Assuming that all tubal ligations could have been OS and 75% of hysterectomies with ovarian conservation could have included OS, our data indicate 76 932 missed opportunities for ovarian cancer prevention.
RESUMEN
BACKGROUND: Opportunistic salpingectomy (OS) is the removal of fallopian tubes during hysterectomy for benign indications or instead of tubal ligation, for the purpose of preventing ovarian cancer. We determined rates of OS at the time of hysterectomy and tubal sterilization and examined how they changed over the study period. METHODS: Using data from the Canadian Institute for Health Information's Discharge Abstract Database and National Ambulatory Care Reporting System for all Canadian provinces and territories (except Quebec) between the fiscal years 2011 and 2016, we conducted a descriptive analysis of all patients aged 15 years or older who underwent hysterectomy or tubal sterilization. We excluded those with diagnostic codes for any gynecologic cancer and those who underwent unilateral salpingectomy. We examined the proportion who had OS during their hysterectomy and compared the proportion of tubal sterilizations that were OS with the proportion that were tubal ligations. RESULTS: A total of 318 528 participants were included in the study (mean age 42.5 yr). The proportion of hysterectomies that included OS increased from 15.4% in 2011 to 35.5% by 2016. With respect to tubal sterilization, the rate of OS increased from 6.5% of all tubal sterilizations in 2011 to 22.0% in 2016. There was considerable variation across jurisdictions in 2016, with British Columbia having the highest rates (53.2% of all hysterectomies and 74.0% of tubal sterilizations involved OS). INTERPRETATION: The rates of OS increased between 2011 and 2016, but there was considerable variation across the included jurisdictions. Our study indicates room for rates of OS to increase across many of the included jurisdictions.

Importance: Opportunistic salpingectomy (OS), which is the removal of fallopian tubes during hysterectomy or instead of tubal ligation without removal of ovaries, is recommended to prevent ovarian cancer, particularly serous ovarian cancer. However, the effectiveness of OS is still undetermined. Objective: To examine observed vs expected rates of ovarian cancer among individuals who have undergone OS. Design, Setting, and Participants: This is a population-based, retrospective cohort study of all individuals in British Columbia, Canada, who underwent OS or a control surgery (hysterectomy alone or tubal ligation) between 2008 and 2017, with follow-up until December 31, 2017. Those with any gynecological cancer diagnosed before or within 6 months of their procedure were excluded. Data analysis was performed from April to August 2021. Exposures: Removal of both fallopian tubes at the time of hysterectomy or instead of tubal ligation while leaving ovaries intact. Main Outcomes and Measures: An ovarian cancer diagnosis listed in the British Columbia Cancer Registry. Age-specific rates of epithelial and serous ovarian cancer in the control group were combined with the specific follow-up time in the OS group to calculate expected numbers (and 95% CIs) of ovarian cancers in the OS group. These were compared with observed numbers. Age-adjusted expected and observed numbers of breast and colorectal cancers were also examined in the OS group. Results: There were 25â¯889 individuals who underwent OS (mean [SD] age, 40.2 [7.1] years; median [IQR] follow-up, 3.2 [1.6-5.1] years) and 32â¯080 who underwent hysterectomy alone or tubal ligation (mean [SD] age, 38.2 [7.9] years; median [IQR] follow-up, 7.3 [4.6-8.7] years). There were no serous ovarian cancers in the OS group and 5 or fewer epithelial ovarian cancers. The age-adjusted expected number was 5.27 (95% CI, 1.78-19.29) serous cancers and 8.68 (95% CI, 3.36-26.58) epithelial ovarian cancers. Age-adjusted expected vs observed numbers of breast cancers (22.1 expected vs 23 observed) and colorectal cancers (9.35 expected vs 8 observed) were not significantly different. Conclusions and Relevance: In this cohort study, the OS group had significantly fewer serous and epithelial ovarian cancers than were expected according to the rate at which they arose in the control group. These findings suggest that OS is associated with reduced ovarian cancer risk.

Since 2008, girls in British Columbia (BC), Canada, have been offered HPV vaccination through a school-based, publicly funded immunization program. The oldest birth cohort eligible for the vaccination program was born in 1994 and uptake is on average 63%. To evaluate the impact of the HPV vaccine in BC, ecological trends in cervical intraepithelial neoplasia (CIN) rates were assessed in young women before and after the implementation of the HPV vaccination program. Information on all Pap smears and histopathological abnormalities, in calendar years 2004-2017 in women 16-28 years of age in BC were obtained from the population-based BC Cancer Cervix Screening Program database. Rates of CIN 2 and 3 were calculated as the number of cases divided by the number of cytology specimens for that period. Rate ratios (RR) were calculated by negative binomial piecewise regression. Age-centered incidence rates of CIN 2 and 3 in BC declined significantly among women 16-23 years of age after HPV vaccine introduction compared to before vaccine introduction. The overall reduction postvaccination for CIN2 and 3 in women 16-23 years was respectively 62% (95% CI 54-68%) and 65% (95% CI 58-71%). Age-specific rates for CIN2 significantly declined for those 18-22 years of age and for those 19, 20 and 23 years of age for CIN3. Among women 24-28 years of age no decline in CIN2 and 3 rate over time was observed. The observed reduction in CIN 2 and 3 rates since the introduction of the school-based HPV vaccine program might illustrate the population impact of the BC provincial school-based HPV vaccination program.

BACKGROUND: The fallopian tube may often be the site of origin for the most common and lethal form of ovarian cancer, high-grade serous ovarian cancer. As a result, many colleges of obstetrics and gynecology, which include the American College of Obstetricians and Gynecologists, are recommending surgical removal of the fallopian tube (bilateral salpingectomy) at the time of other gynecologic surgeries (particularly hysterectomy and tubal sterilization) in women at general population risk for ovarian cancer, collectively referred to as opportunistic salpingectomy. Previous research has illustrated no increased risk of complications after opportunistic salpingectomy. However, most studies that have examined potential hormonal consequences of opportunistic salpingectomy have had limited follow-up time and have focused on surrogate hormonal markers. OBJECTIVE: We examine whether there are differences in physician visits for menopause and filling a prescription for hormone replacement therapy among women who undergo opportunistic salpingectomy in the population of British Columbia, Canada. STUDY DESIGN: We identified all women who were ≤50 years old in British Columbia who underwent opportunistic salpingectomy from 2008-2014. We compared women who underwent opportunistic salpingectomy at hysterectomy with women who underwent hysterectomy alone and women who underwent opportunistic salpingectomy for sterilization with women who underwent tubal ligation. We used Cox Proportional hazards models to model time to physician visits for menopause and for filling a prescription for hormone replacement therapy. We calculated adjusted hazards ratios for these outcomes and adjusted for other gynecologic conditions, surgical approach, and patient age. We performed an age-stratified analysis (<40, 40-44, 45-49 years) and conducted a sensitivity analysis that included only women with ≥5 years of follow up. RESULTS: We included 41,413 women in the study. There were 6861 women who underwent hysterectomy alone, 6500 who underwent hysterectomy with opportunistic salpingectomy, 4479 who underwent hysterectomy with bilateral salpingo-oophorectomy, 18,621 who underwent tubal ligation, and 4952 who underwent opportunistic salpingectomy for sterilization. In women who underwent opportunistic salpingectomy, there was no difference in time to the first physician visit related to menopause for both women who underwent hysterectomy with opportunistic salpingectomy (adjusted hazard ratio, 0.98; 95% confidence interval, 0.88-1.09) and women who underwent opportunistic salpingectomy for sterilization (adjusted hazard ratio, 0.92; 95% confidence interval, 0.77-1.10). There was also no difference in time to filling a prescription for hormone replacement therapy for women who underwent hysterectomy with opportunistic salpingectomy or opportunistic salpingectomy for sterilization (adjusted hazard ratio, 0.82; 95% confidence interval, 0.72-0.92; and adjusted hazard ratio, 1.00; 95% confidence interval, 0.89-1.12; respectively). In contrast, we report significantly increase hazards for time to physician visit for menopause (adjusted hazard ratio, 1.95; 95% confidence interval, 1.78, 2.13) and filling a prescription for hormone replacement therapy (adjusted hazard ratio, 3.80; 95% confidence interval, 3.45, 4.18) among women who underwent hysterectomy with bilateral salpingo-oophorectomy. There were no increased hazards for physician visits for menopause or initiation of hormone replacement therapy among women who underwent opportunistic salpingectomy in any of the age-stratified analyses, nor among women with at least 5 years of follow up. CONCLUSION: Our results reveal no indication of an earlier age of onset of menopause among the population of women who underwent hysterectomy with opportunistic salpingectomy and opportunistic salpingectomy for sterilization as measured by physician visits for menopause and initiation of hormone replacement therapy. Our findings are reassuring, given that earlier age at menopause is associated with increased mortality rates, particularly from cardiovascular disease.

OBJECTIVES: The primary obkective was to determine the prevalence of (a) a positive anal cancer screen and (b) histological anal high-grade squamous intraepithelial lesion (HSIL) in women undergoing surveillance for previously diagnosed and treated human papillomavirus (HPV)-associated vulvar HSIL. The secondary objective was to determine the patients' acceptability of the screen. MATERIALS AND METHODS: This is a single-institution, cross-sectional pilot study. Women, aged 30 to 80 years, with a history of biopsy-proven vulvar HSIL were invited to undergo screening for anal cancer. Positive screen characterized by abnormalities in any of the following: anal high-risk HPV (HR-HPV); anal cytology; and digital anorectal examination. All women with an abnormal screen were referred for high-resolution anoscopy. All women completed a postscreen questionnaire. RESULTS: Fifty-seven patients were recruited. The median (interquartile range) age was 61.5 (51.0-68.0) years. The prevalence of a positive screen was 56.1% (95% CI = 43.3%-68.2%). Of the 32 screen-positive patients, 12 had both abnormal cytology and HR-HPV, 3 had positive HR-HPV alone, and 17 had abnormal cytology alone. Of the 29 patients with a positive screen who went on to anoscopy, the prevalence of anal HSIL was 33.3% (95% CI = 19.2%-51.2%). The prevalence of anal HSIL among all of those who had screening (N = 57) was 18.2% (95% CI = 10.2%-30.3%). The examination was well tolerated with 100% of patients, indicating that they would have the screening again. CONCLUSIONS: Women with vulvar HSIL have an increased risk of developing anal HSIL. Larger studies are needed to define optimal screening protocols as well as algorithms for management in high-risk populations.

A fiber-based endoscopic imaging system combining narrowband red-green-blue (RGB) reflectance with optical coherence tomography (OCT) and autofluorescence imaging (AFI) has been developed. The system uses a submillimeter diameter rotary-pullback double-clad fiber imaging catheter for sample illumination and detection. The imaging capabilities of each modality are presented and demonstrated with images of a multicolored card, fingerprints, and tongue mucosa. Broadband imaging, which was done to compare with narrowband sources, revealed better contrast but worse color consistency compared with narrowband RGB reflectance. The measured resolution of the endoscopic system is 25 µm in both the rotary direction and the pullback direction. OCT can be performed simultaneously with either narrowband RGB reflectance imaging or AFI.

BACKGROUND: Recent evidence has suggested that the fallopian tube may often be the site of origin for the most common and lethal form of ovarian cancer. As a result, many Colleges of Obstetrics and Gynecology, including the American College of Obstetricians and Gynecology, are recommending surgical removal of the fallopian tube (bilateral salpingectomy) at the time of other gynecologic surgeries (particularly hysterectomy and tubal sterilization) in women at general population risk for ovarian cancer, collectively referred to as opportunistic salpingectomy. OBJECTIVE: Previous research with the use of hospital data has indicated good perioperative safety of opportunistic salpingectomy, but no data on minor complications have been presented. Herein, we examine whether women who undergo opportunistic salpingectomy are at increased risk of minor complications after surgery. STUDY DESIGN: We identified all women in British Columbia who underwent opportunistic salpingectomy between 2008 and 2014 and examined all physician visits in the 2 weeks after discharge from the hospital. We compared women who underwent opportunistic salpingectomy at hysterectomy with women who underwent hysterectomy alone and women who underwent opportunistic salpingectomy for sterilization with women who underwent tubal ligation. We examined visits for surgical infection, surgical complication, orders for laboratory tests, and orders for imaging (x-ray, ultrasound scan, or computed tomography scan) and whether women who underwent opportunistic salpingectomy were more likely to fill a prescription for an antibiotic or analgesic in the 2 weeks after discharge from the hospital. We calculated adjusted odds ratios for these outcomes, adjusting for other gynecologic conditions, surgical approach, and patient age. RESULTS: We included 49,275 women who had undergone a hysterectomy alone, a hysterectomy with opportunistic salpingectomy, a hysterectomy with bilateral salpingo-oophorectomy, a tubal ligation, or an opportunistic salpingectomy for sterilization. In women who had undergone opportunistic salpingectomy, there was no increased risk for physician visits for surgical infection, surgical complication, ordering a laboratory test, or ordering imaging in the 2 weeks after discharge. There was no increased risk of filling a prescription for an antibiotic. However, women who underwent opportunistic salpingectomy were at approximately 20% increased odds of filling a prescription for an analgesic in the 2 weeks after discharge from the hospital (adjusted odds ratio, 1.23; 95% confidence interval, 1.15-1.32 for hysterectomy with opportunistic salpingectomy; adjusted odds ratio, 1.21; 95% confidence interval, 1.14-1.29 for opportunistic salpingectomy for sterilization). CONCLUSION: We report no differences in minor complications between women who undergo opportunistic salpingectomy and women who undergo hysterectomy alone or tubal ligation, except for a slightly increased likelihood of filling a prescription for analgesic medication in the immediate 2 weeks after discharge.

OBJECTIVE: The aim of the study was to determine regression rates of cervical intraepithelial neoplasia (CIN) 2 and 3 in women younger than 24 years, followed conservatively for up to 24 months. MATERIALS AND METHODS: This is a retrospective chart review of colposcopy patients in clinic database based on the following: (1) younger than 24 years at first visit; (2) first visit January 1, 2010, to May 31, 2013, and at least 1 follow-up visit after diagnosis; (3) histologic diagnosis of CIN2+; and (4) optimal conservative management (observation for up to 24 months or to 24 years, whichever occurred first). Patient information and clinical/pathologic data were extracted from charts to examine patient characteristics and treatment outcomes, CIN2+ regression rates, median times to regression for CIN2 versus CIN3 (Kaplan-Meier survival analysis), and predictors of regression (multivariate logistic regression analysis). RESULTS: A total of 154 women met criteria. The most severe histological diagnoses were CIN2 in 99 (64.3%), CIN3 in 51 (33.1%), and adenocarcinoma in situ in 4 (2.6%). Adenocarcinoma in situ was immediately treated. In follow-up, CIN2 regressed to CIN1 or negative in 74 women (74.7%)-median time to regression, 10.8 months. Cervical intraepithelial neoplasia 3 regressed in 11 women (21.6%)-median time to regression not reached (last follow-up censored at 52.7 months). Cervical intraepithelial neoplasia 2 on biopsy, low grade referral Pap, and younger age predicted regression. Overall, 49 women (31.8%) were treated. CONCLUSIONS: Conservative management should continue to be recommended to young women with CIN2. Rigorous retention mechanisms are required to ensure that these women return for follow-up.

OBJECTIVE: The aim of the study was to explore the factors that contributed to the adoption of opportunistic salpingectomies (removal of fallopian at the time of hysterectomy or in lieu of tubal ligation) by gynecologic surgeons in British Columbia (where a knowledge translation initiative took place) and in Ontario (a comparator where no knowledge translation initiative took place). We aimed to understand why the knowledge translation initiative undertaken by OVCARE in British Columbia resulted in such a dramatic uptake in opportunistic salpingectomy. METHODS: We undertook a qualitative evaluation of clinicians' decisions about whether or not they should adopt the practice of opportunistic salpingectomy based on interviews with gynecologic surgeons in British Columbia and Ontario (n = 28). The analysis draws from the Consolidated Framework for Implementation Research. RESULTS: Regional cohesion combined with practice change information exposure and thought leader support were important in explaining differences in adoption levels between participants. The British Columbian knowledge translation campaign was successful because provincial thought leaders exposed gynecologic surgeons to recommendations through multiple sources within a highly socially cohesive environment wherein clinicians felt pressure to adopt the recommendations. In both provinces, high adopters often believed that the workload and surgical risk associated with the adoption was low and the potential benefit-because of limited ovarian cancer detection and treatment options-was high. CONCLUSION: This research points to the important role that local professional networks can play in encouraging clinicians to change their practice by creating a cohesive regional environment where clinicians are repeatedly exposed to important information and supported in their practice change by local thought leaders.

BACKGROUND: Identifying female carriers of BRCA1 and BRCA2 mutations is imperative for prevention of ovarian cancer and breast cancer. There are five major histologic subtypes of ovarian cancer and high grade serous cancer (the most common) is reported in 75-100% of BRCA1 and BRCA2 mutation carriers. We examined histology-based referral to the Hereditary Cancer Program following an educational prevention campaign recommending BRCA1 and BRCA2 mutation screening for all high-grade serous cancer patients. METHODS: We conducted a population-based retrospective study in the province of British Columbia, Canada that included all patients visiting the Hereditary Cancer Program for genetic counselling for BRCA1 and BRCA2 mutation between 2001 and 2014. We examined the difference in rates of BRCA1 and BRCA2 testing between serous cancer patients and endometrioid and clear cell cancer patients using a differences in differences analysis. We also calculated the mean number of family members tested for every BRCA1 and BRCA2 identified ovarian cancer patient before and after the educational campaign. RESULTS: There were 5712 women tested for a BRCA1 and BRCA2 mutation at the HCP between 2001 and 2014, 887 of which had previously received a diagnosis of ovarian cancer. By 2013, 43% of serous cancer patients were being tested for BRCA1 and BRCA2 mutations compared with 20% of endometrioid and clear cell patients (p < 0.001). The mean number of family members tested for each BRCA1 and BRCA2 positive ovarian cancer patient increased after the educational campaign from 2.54 to 3.27 (p = 0.071), and the number of family members identified as BRCA positive also increased significantly. CONCLUSIONS: Recommendations for histology-based referral significantly increased the likelihood of serous cancer patients being tested for BRCA mutations. There was also an increase in the number of carrier tests performed for each BRCA1 and BRCA2 index ovarian cancer patient.

Differentiated vulvar intrapeithelial neoplasia (dVIN) is an human papillomavirus (HPV)-independent precursor of squamous cell carcinoma (SCC), and the aim of this study was to better characterize its natural history. Cases of dVIN were identified from the pathology archives. Outcomes of patients with dVIN only, without associated invasive SCC, were compared with a cohort of patients with high-grade squamous intraepithelial lesion [HSIL(VIN3)]. Eighteen patients diagnosed with dVIN with adjacent invasive SCC (SCC/dVIN) and 7 patients with dVIN only, without invasive carcinoma, were identified. Mean age in both cohorts was 75 yr. All lesions but 1 were unifocal. In 35% of SCC/dVIN cases the surgical resection margins were positive for SCC, with 75% and 60% having margins positive for dVIN in the SCC/dVIN and dVIN-only cohorts, respectively. In total, 23/25 women with dVIN only or dVIN/SCC, for whom there was follow-up information, experienced either progression to or recurrence of invasive SCC, respectively, at a median of 1.1 yr, including all but 1 case of dVIN only, where the median time of progression to invasive SCC was 1.9 yr. A total of 22/25 women died of disease with a median overall survival of 3.4 yr. The outcome (i.e. progression to invasive carcinoma) of patients with dVIN only was significantly worse than that of a comparison group of 18 patients with HSIL(VIN3) (progression-free survival log-rank, P<0.001; disease-specific survival, P=0.04; overall survival, P=0.01). Six of 7 patients with dVIN only developed invasive carcinoma on follow-up, compared with 0 of 18 patients with HSIL(VIN3). The diagnosis of dVIN indicates the presence of a high-risk human papillomavirus-negative precursor of invasive SCC. These patients are likely to progress to invasive carcinoma over a relatively short period, at which point their prognosis is guarded.

AIMS: Vulvar squamous cell carcinoma (VSCC) can be subdivided by human papillomavirus (HPV) status into two clinicopathological entities. Studies on the prognostic significance of HPV in VSCC are discordant. METHODS AND RESULTS: We performed a retrospective analysis of overall survival (OS), disease-specific survival (DSS) and progression-free survival (PFS) in 217 patients with VSCC. Cases were extracted from an era of more aggressive en-bloc radical dissections (1985-95) and more localized radical surgery through separate vulvar and groin excisions (1996-2005). p16 immunohistochemistry was used as a surrogate for HPV status. HPV status could be determined in 197 tumours, 118 HPV-independent and 79 HPV-associated tumours. Patients with HPV-associated tumours were younger (mean 58.8 versus 71.6 years for HPV-independent tumours, P < 0.0001) and more likely to have prior abnormal cervical cytology (41.1 versus 5.6% for HPV-independent tumours, P < 0.0001). In univariable analysis, patients with HPV-associated tumours had superior PFS [hazard ratio (HR): 0.37, 95% confidence interval (CI): 0.18-0.70], DSS (HR: 0.19, 95% CI: 0.08-0.41) and OS (HR: 0.35, 95% CI: 0.21-0.59). This was driven by worse outcomes (PFS, DSS and OS) for patients with HPV-independent tumours compared with HPV-associated tumours who underwent surgery after 1995. After adjusting for age and stage in multivariable analysis, patients with HPV-associated tumours showed superior PFS (HR: 0.25, 95% CI: 0.07-0.77) and DSS (HR: 0.21, 95% CI: 0.04-0.78). CONCLUSIONS: VSCC can be stratified into two prognostically different diseases based on p16 immunostaining. HPV status was associated only with prognosis in the cohort that underwent surgery after 1995, suggesting that more conservative surgery may have led to worse outcomes for patients with HPV-independent tumours.

Sexual health is an integral component of quality of life for cancer survivors, and is often negatively impacted by treatment. Geographic limitations often prohibit survivors from accessing sexual health programs designed to address their needs. This study examined the efficacy of an online, 12-week psychoeducational program, which included elements of mindfulness meditation, for sexual difficulties in survivors of colorectal or gynecologic cancer. Complete pre- and postintervention data were available for 46 women (mean age 55.0, SD 9.6) and 15 men (mean age 59.7, SD 6.8). Women experienced significant improvements in sex-related distress (p < .001), sexual function (p < .001 and p < .01), and mood (p < .001); these results were maintained at six months follow-up. Men's improvement in desire was not significant (p = .06), whereas intercourse satisfaction was (p < .05) immediately after the program, but not at follow-up. In order to more fully explore women's experiences, interviews were carried out with six participants and analyzed using narrative inquiry. Women shared a feeling of renewed hope for regaining their sex lives, and expressed that they would have valued an interactive component to the program. These findings suggest that an online, unidirectional psychoeducational program is feasible, and may be effective for women survivors of gynecologic and colorectal cancer, but further work is needed to ensure that online interventions address the sexual health needs of male survivors.

BACKGROUND: Ovarian cancer is the leading cause of death due to gynecologic malignancy and the fifth most common cause of cancer deaths in developed countries. Recent evidence has indicated that the most common and lethal form of ovarian cancer originates in the distal fallopian tube, and recommendations for surgical removal of the fallopian tube (bilateral salpingectomy) at the time of other gynecologic surgeries (particularly hysterectomy and tubal sterilization) have been made, most recently by the American Congress of Obstetricians and Gynecologists. OBJECTIVE: We sought to assess the uptake and perioperative safety of bilateral salpingectomy at the time of hysterectomy and tubal sterilization in the United States and to examine the factors associated with increased likelihood of bilateral salpingectomy. STUDY DESIGN: The Nationwide Inpatient Sample was used to identify all girls and women 15 years or older without gynecologic cancer who underwent inpatient hysterectomy or tubal sterilization, with and without bilateral salpingectomy, from 2008 through 2013. Weighted estimates of national rates of these procedures were calculated and the number of procedures performed estimated. Safety was assessed by examining rates of blood transfusions, perioperative complications, postprocedural infection, and fever, and adjusted odds ratios were calculated comparing hysterectomy with salpingectomy with hysterectomy alone. RESULTS: We included 425,180 girls and women who underwent inpatient hysterectomy from 2008 through 2013 representing a national cohort of 2,036,449 (95% confidence interval, 1,959,374-2,113,525) girls and women. There was an increase in the uptake of hysterectomy with bilateral salpingectomy of 371% across the study period, with 7.7% of all hysterectomies including bilateral salpingectomy in 2013 (15.8% among girls and women retaining their ovaries). There were only 1195 salpingectomies for sterilization, thus no further comparisons were possible. In the girls and women who had hysterectomy with bilateral salpingectomy, there was no increased risk for blood transfusion (adjusted odds ratio, 0.95; 95% confidence interval, 0.86-1.05) postoperative complications (adjusted odds ratio, 0.97; 95% confidence interval, 0.88-1.07), postoperative infections (adjusted odds ratio, 1.26; 95% confidence interval, 0.90-1.78), or fevers (adjusted odds ratio, 1.33; 95% confidence interval, 1.00-1.77) compared with women undergoing hysterectomy alone. Younger age, private for-profit hospital setting, larger hospital size, and indication for hysterectomy were all associated with increased likelihood of getting a hysterectomy with bilateral salpingectomy in women retaining their ovaries. CONCLUSION: Our results suggest that hysterectomy with bilateral salpingectomy is significantly increasing in the United States and is not associated with increased risks of postoperative complications.

Current diagnostic capabilities and limitations of fluorescence endomicroscopy in the cervix are assessed by qualitative and quantitative image analysis. Four cervical tissue types are investigated: normal columnar epithelium, normal and precancerous squamous epithelium, and stromal tissue. This study focuses on the perceived variability within and the subtle differences between the four tissue groups in the context of endomicroscopic in vivo pathology. Conclusions are drawn on the general ability to distinguish and diagnose tissue types, on the need for imaging depth control to enhance differentiation, and on the possible risks for diagnostic misinterpretations.

A fiber optic imaging approach is presented using structured illumination for quantification of almost pure epithelial backscattering. We employ multiple spatially modulated projection patterns and camera-based reflectance capture to image depth-dependent epithelial scattering. The potential diagnostic value of our approach is investigated on cervical ex vivo tissue specimens. Our study indicates a strong backscattering increase in the upper part of the cervical epithelium caused by dysplastic microstructural changes. Quantization of relative depth-dependent backscattering is confirmed as a potentially useful diagnostic feature for detection of precancerous lesions in cervical squamous epithelium.

BACKGROUND: Cervical cancer remains a major health problem, especially in developing countries. Colposcopic examination is used to detect high-grade lesions in patients with a history of abnormal pap smears. New technologies are needed to improve the sensitivity and specificity of this technique. We propose to test the potential of fluorescence confocal microscopy to identify high-grade lesions. METHODS: We examined the quantification of ex vivo confocal fluorescence microscopy to differentiate among normal cervical tissue, low-grade Cervical Intraepithelial Neoplasia (CIN), and high-grade CIN. We sought to (1) quantify nuclear morphology and tissue architecture features by analyzing images of cervical biopsies; and (2) determine the accuracy of high-grade CIN detection via confocal microscopy relative to the accuracy of detection by colposcopic impression. Forty-six biopsies obtained from colposcopically normal and abnormal cervical sites were evaluated. Confocal images were acquired at different depths from the epithelial surface and histological images were analyzed using in-house software. RESULTS: The features calculated from the confocal images compared well with those features obtained from the histological images and histopathological reviews of the specimens (obtained by a gynecologic pathologist). The correlations between two of these features (the nuclear-cytoplasmic ratio and the average of three nearest Delaunay-neighbors distance) and the grade of dysplasia were higher than that of colposcopic impression. The sensitivity of detecting high-grade dysplasia by analysing images collected at the surface of the epithelium, and at 15 and 30 µm below the epithelial surface were respectively 100, 100, and 92 %. CONCLUSIONS: Quantitative analysis of confocal fluorescence images showed its capacity for discriminating high-grade CIN lesions vs. low-grade CIN lesions and normal tissues, at different depth of imaging. This approach could be used to help clinicians identify high-grade CIN in clinical settings.

OBJECTIVE: The Royal College of Physicians and Surgeons of Canada requires that residents demonstrate competence in health advocacy (HA). We sought to develop and implement a national educational module for obstetrics and gynaecology residents to address the role of HA. This pilot program was centred on cervical cancer prevention, which lends itself to applying the principles of advocacy. METHODS: An educational module was developed and disseminated to all obstetrics and gynaecology residency programs in Canada. The module describes options for HA involving cervical dysplasia screening, such as an outreach clinic or a forum for public/student education, which were to be implemented during Cervical Cancer Awareness Week. The measures of success were the number of programs implementing the curriculum, number of residents who participated, diversity of projects implemented, individuals (patients or learners) reached by the program, and the overall experience of the trainees. RESULTS: Three programs implemented the curriculum in 2011, one in 2012, and seven in 2013. After three years, the module has involved seven of 16 medical schools, over 100 residents, and thousands of women either directly or indirectly. Additionally, attributes of HA experienced by the residents were identified: teamwork, leadership, increased systems knowledge, increased social capital within the community, creativity, innovation, and adaptability. CONCLUSION: We have demonstrated that an educational module can be implemented nationally, helping our residents fulfill their HA requirements. Other specialties could use this module in building HA into their own programs.
Objectif : Le Collège royal des médecins et chirurgiens du Canada exige que les résidents fassent preuve de compétence dans le rôle de promoteur de la santé (PS ou promotion de la santé). Nous avons cherché à élaborer et à mettre en Åuvre, à l'intention des résidents en obstétrique-gynécologie, un module pédagogique national traitant de ce rôle de PS. Ce programme pilote était centré sur la prévention du cancer du col utérin, soit un sujet se prêtant bien à l'application des principes de la promotion de la santé. Méthodes : Un module pédagogique a été élaboré et transmis à tous les programmes de résidence en obstétrique-gynécologie au Canada. Ce module décrit les options de PS mettant en jeu le dépistage de la dysplasie cervicale (telles qu'une clinique visant l'élargissement de la population desservie ou un forum d'éducation visant le public / la population étudiante) qui devaient être mises en Åuvre au cours de la Semaine de sensibilisation au cancer du col de l'utérus. La réussite a été mesurée en fonction du nombre de programmes mettant en Åuvre le curriculum, du nombre de résidents y ayant participé, de la diversité des projets mis en Åuvre, de la nature des personnes (patientes ou apprenants) atteintes par le programme et de l'expérience globale des stagiaires. Résultats : Trois programmes ont mis en Åuvre le curriculum en 2011, un programme l'a fait en 2012 et sept l'ont fait en 2013. Après trois ans, le module s'est attiré la participation directe ou indirecte de sept des 16 facultés de médecine, de plus de 100 résidents et de milliers de femmes. De plus, les attributs de la PS vécus par les résidents ont été identifiés : travail d'équipe, leadership, connaissances accrues au sujet des systèmes, capital social accru au sein de la communauté, créativité, innovation et adaptabilité. Conclusion : Nous avons démontré qu'un module pédagogique, visant à aider nos résidents à répondre à leurs exigences en matière de PS, peut être mis en Åuvre à l'échelle nationale. D'autres spécialités pourraient utiliser ce module pour incorporer la PS dans leurs programmes respectifs.
