RESUMO

We report a case of a 32-year-old gravida 1 para 0 with a copper intrauterine device in place and a newly diagnosed pregnancy at 5 weeks gestation. Serum human chorionic gonadotropin (hCG) was 23,940 mIU/mL and transvaginal ultrasound demonstrated a presumed right adnexal ectopic pregnancy with fetal cardiac activity. Upon laparoscopic entry, a 3 cm vascular mass consistent with ectopic pregnancy was noted densely adherent to the cecum, adjacent to the ileocecal junction. Given difficult tissue plane dissection and bleeding, a 4 cm mini-laparotomy was made and the mass was bluntly dissected away from the bowel implantation site. The bowel was oversewn. The patient's postoperative course was uncomplicated.

RESUMO

OBJECTIVES/PURPOSE: The reproducibility and sensitivity of image-based colposcopy is low, but agreement on lesion presence and location remains to be explored. Here, we investigate the interobserver agreement on lesions on colposcopic images by evaluating and comparing marked lesions on digitized colposcopic images between colposcopists. METHODS: Five colposcopists reviewed images from 268 colposcopic examinations. Cases were selected based on histologic diagnosis, i.e., normal/cervical intraepithelial neoplasia (CIN)1 ( n = 50), CIN2 ( n = 50), CIN3 ( n = 100), adenocarcinoma in situ ( n = 53), and cancer ( n = 15). We obtained digitized time-series images every 7-10 seconds from before acetic acid application to 2 minutes after application. Colposcopists were instructed to digitally annotate all areas with acetowhitening or suspect of lesions. To estimate the agreement on lesion presence and location, we assessed the proportion of images with annotations and the proportion of images with overlapping annotated area by at least 4 (4+) colposcopists, respectively. RESULTS: We included images from 241 examinations (1 image from each) with adequate annotations. The proportion with a least 1 lesion annotated by 4+ colposcopists increased by severity of histologic diagnosis. Among the CIN3 cases, 84% had at least 1 lesion annotated by 4+ colposcopists, whereas 54% of normal/CIN1 cases had a lesion annotated. Notably, the proportion was 70% for adenocarcinoma in situ and 71% for cancer. Regarding lesion location, there was no linear association with severity of histologic diagnosis. CONCLUSION: Despite that 80% of the CIN2 and CIN3 cases were annotated by 4+ colposcopists, we did not find increasing agreement on lesion location with histology severity. This underlines the subjective nature of colposcopy.

RESUMO

BACKGROUND: The comparative long-term survival of first-line biologics for UC and reasons for drug discontinuation are poorly understood. We sought to compare the long-term drug survival related to non-response (NR) and adverse effects (AEs) for vedolizumab, adalimumab, and infliximab among biologic-naïve patients with UC. METHODS: This was a retrospective cohort study of adult biologic-naïve patients with moderate-to-severe UC initiating vedolizumab, adalimumab, or infliximab 6/1/14-12/31/20 at a large academic medical center. The primary outcome was time to biologic discontinuation for primary or secondary NR (including colectomy). The secondary outcome was time to biologic discontinuation due to AEs. Inverse probability of treatment-weighted (IPTW) Cox regression was used to perform three pair-wise comparisons of drug survival. RESULTS: The cohort included 805 patients with UC who initiated vedolizumab (n = 195), adalimumab (n = 278), or infliximab (n = 332). The adjusted hazard of biologic discontinuation for NR was significantly lower for vedolizumab vs adalimumab (HR 0.51, 95% CI 0.34-0.75), similar for vedolizumab vs infliximab (HR 1.32, 95% CI 0.79-2.18), and greater for adalimumab vs infliximab (HR 2.07, 95% CI 1.51-2.86). The adjusted hazard of discontinuation for AEs was significantly lower for vedolizumab vs adalimumab (HR 0.25, 95% CI 0.09-0.64), lower for vedolizumab vs infliximab (HR 0.21, 95% CI 0.10-0.46), and similar for adalimumab vs infliximab (HR 0.85, 95% CI 0.53-1.35). CONCLUSIONS: There was greater survival of vedolizumab compared to adalimumab for clinical response and greater survival of vedolizumab compared to both adalimumab and infliximab for AEs. These long-term data support the use of vedolizumab as a first-line biologic over adalimumab for biologic-naïve patients with UC.

RESUMO

OBJECTIVE: Anemia is prevalent in patients with gynecologic cancers and is associated with increased peri-operative morbidity. We aimed to characterize risk factors for pre-operative anemia and describe outcomes among patients undergoing surgery by a gynecologic oncologist to identify potential areas for impactful intervention. METHODS: We analyzed major surgical cases performed by a gynecologic oncologist in the National Surgical Quality Improvement Program (NSQIP) database from 2014 to 2019. Anemia was defined as hematocrit <36%. Demographic characteristics and peri-operative variables for patients with and without anemia were compared using bivariable tests. Odds of peri-operative complications in patients stratified by pre-operative anemia were calculated using logistic regression models. RESULTS: Among 60 017 patients undergoing surgery by a gynecologic oncologist, 23.1% had pre-operative anemia. Women with ovarian cancer had the highest rate of pre-operative anemia at 39.7%. Patients with advanced-stage cancer had a higher risk of anemia than early-stage disease (42.0% vs 16.3%, p≤0.001). In a logistic regression model adjusting for potential demographic, cancer-related, and surgical confounders, patients with pre-operative anemia had increased odds of infectious complications (odds ratio (OR) 1.16, 95% CI 1.07 to 1.26), thromboembolic complications (OR 1.39, 95% CI 1.15 to 1.68), and blood transfusion (OR 5.78, 95% CI 5.34 to 6.26). CONCLUSIONS: There is a high rate of anemia in patients undergoing surgery by a gynecologic oncologist, particularly those with ovarian cancer and/or advanced malignancy. Pre-operative anemia is associated with increased odds of peri-operative complications. Interventions designed to screen for and treat anemia in this population have the potential for significant impact on surgical outcomes.

RESUMO

OBJECTIVES: Individuals treated for cervical intraepithelial neoplasia grade 2 or worse (CIN2+) are at long-term risk of persistent or recurrent disease despite treatment. This committee opinion aims to summarize and provide evidence-based recommendations for adjuvant human papillomavirus (HPV) vaccination based on available, published literature. METHODS: A task force from the ASCCP Practice Committee reviewed current Centers for Disease Control and Prevention (CDC) guidelines and previously published literature about the role of adjuvant HPV vaccination in previously unvaccinated individuals undergoing treatment for CIN2+ and other HPV-related diseases. RESULTS: Current CDC guidelines recommend routine or catch-up HPV vaccination for individuals aged 9 to 26 years, and shared decision making regarding vaccination for individuals aged 27 to 45 years. Multiple published studies suggest a possible benefit for adjuvant HPV vaccination in previously unvaccinated individuals undergoing treatment for CIN2+. CONCLUSIONS: The American Society for Colposcopy and Cervical Pathology recommends adherence to current CDC recommendations for vaccination of individuals aged 9 to 26 years and consideration of the possible benefit of adjuvant HPV vaccination during shared decision making for previously unvaccinated individuals aged 27 to 45 years who are undergoing treatment for CIN2+.

RESUMO

Ustekinumab has been shown to be effective for the treatment of ulcerative colitis (UC); however, >40% of patients have suboptimal clinical response after induction and maintenance dosing every 8 weeks.1,2 The best management approach for these patients is unclear. Many undergo empiric dose intensification to every 4 weeks or every 6 weeks, a nonstandardized decision because of limited data supporting therapeutic drug monitoring of ustekinumab.3 In Crohn's disease, approximately 50% of patients undergo ustekinumab dose intensification, which seems to be effective based on prior work from our group and others.4-8 However, similar data in UC are lacking. In this real-world multicenter cohort study, we sought to identify predictors and outcomes of ustekinumab dose intensification in UC.

RESUMO

OBJECTIVE: Colposcopy is an important part of cervical screening/management programs. Colposcopic appearance is often classified, for teaching and telemedicine, based on static images that do not reveal the dynamics of acetowhitening. We compared the accuracy and reproducibility of colposcopic impression based on a single image at one minute after application of acetic acid versus a time-series of 17 sequential images over two minutes. METHODS: Approximately 5000 colposcopic examinations conducted with the DYSIS colposcopic system were divided into 10 random sets, each assigned to a separate expert colposcopist. Colposcopists first classified single two-dimensional images at one minute and then a time-series of 17 sequential images as 'normal,' 'indeterminate,' 'high grade,' or 'cancer'. Ratings were compared to histologic diagnoses. Additionally, 5 colposcopists reviewed a subset of 200 single images and 200 time series to estimate intra- and inter-rater reliability. RESULTS: Of 4640 patients with adequate images, only 24.4% were correctly categorized by single image visual assessment (11% of 64 cancers; 31% of 605 CIN3; 22.4% of 558 CIN2; 23.9% of 3412 < CIN2). Individual colposcopist accuracy was low; Youden indices (sensitivity plus specificity minus one) ranged from 0.07 to 0.24. Use of the time-series increased the proportion of images classified as normal, regardless of histology. Intra-rater reliability was substantial (weighted kappa = 0.64); inter-rater reliability was fair ( weighted kappa = 0.26). CONCLUSION: Substantial variation exists in visual assessment of colposcopic images, even when a 17-image time series showing the two-minute process of acetowhitening is presented. We are currently evaluating whether deep-learning image evaluation can assist classification.

RESUMO

Patients with inflammatory bowel disease (IBD) develop coronavirus disease 2019 (COVID-19) at similar rates as the general population, and there was initial concern regarding potential for severe illness.1-4 Vaccinations were authorized for emergency use in the United States in December 2020 and aim to halt the spread of COVID-19. However, there are concerns that people will be hesitant to receive the vaccine for a variety of reasons including insufficient data in certain populations including those with IBD. We surveyed patients with IBD to identify potential concerns regarding COVID-19 vaccination.

RESUMO

BACKGROUND & AIMS: Clostridioides difficile infection (CDI) harms a large proportion of patients with cirrhosis. Fecal microbiota transplantation (FMT) is recommended for recurrent CDI, but its effects in patients with cirrhosis have not been established. We performed a multicenter observational study to evaluate the efficacy and safety of FMT for CDI in patients with cirrhosis. METHODS: We performed a retrospective study of 63 adults with cirrhosis (median model for end-stage liver disease score, 14.5; 24 patients with decompensated cirrhosis) who underwent FMT for CDI from January 2012 through November 2018 at 8 academic centers in the United States, Canada, and Italy. We collected data on patient demographics and characteristics of cirrhosis, CDI, and FMT from medical records and compared differences among patients with different severities of cirrhosis, and FMT successes vs failures at the 8-week follow-up evaluation. We also obtained data on adverse events (AEs) and severe AEs within 12 weeks of FMT. RESULTS: Patients underwent FMT for recurrent CDI (55 of 63; 87.3%), severe CDI (6 of 63; 9.5%), or fulminant CDI (2 of 63; 3.2%) primarily via colonoscopy (59 of 63; 93.7%) as outpatients (47 of 63; 76.8%). FMT success was achieved for 54 patients (85.7%). Among FMT failures, a higher proportion used non-CDI antibiotics at the time of FMT (44.4% vs 5.6%; P < .001), had Child-Pugh scores of B or C (100% vs 37.7%; P < .001), used probiotics (77.8% vs 24.1%; P = .003), had pseudomembranes (22.2% vs 0; P = .018), and underwent FMT as inpatients (45.5% vs 19%; P = .039), compared with FMT successes. In multivariable analysis, use of non-CDI antibiotics at the time of FMT (odds ratio, 17.43; 95% CI, 2.00-152.03; P = .01) and use of probiotics (odds ratio, 11.9; 95% CI, 1.81-78.3; P = .01) were associated with a greater risk of FMT failure. FMT-related AEs occurred in 33.3% of patients (21 of 63)-most were self-limited abdominal cramps or diarrhea. There were only 5 severe AEs that possibly were related to FMT; none involved infection or death. CONCLUSIONS: In a retrospective study, we found FMT to be safe and effective for the treatment of CDI in patients with cirrhosis.

RESUMO

Venous thromboembolism (VTE) is a common cause of morbidity and mortality in women with gynecologic malignancies. This practice statement provides clinical data and overall quality of evidence regarding the use of direct oral anticoagulants (DOACs) in this patient population. Specifically, it reviews patient selection, safety measures, and nuances of perioperative use of these medications. The scope of this document is limited to DOAC use in gynecologic oncology rather than a broad discussion of VTE prophylaxis and management in general. The following recommendations and examination of extant data are based on DOAC trials conducted primarily in mixed populations with different cancer subtypes. Many of these trials include few, or no, women with gynecologic cancer. However, because there is very limited data in gynecologic cancer-specific populations, the results of these studies represent the best available evidence to support treatment recommendations in our patients. The members of the Society of Gynecologic Oncology (SGO) Clinical Practice Committee believe that the results of these studies may be extrapolated, with caution, to VTE treatment and prophylaxis for patients with gynecologic cancer.

RESUMO

ABSTRACT: The American Cancer Society (ACS) released updated cervical cancer screening guidelines in 2020 that endorse a shift in practice to primary human papillomavirus (HPV) screening in people with a cervix, beginning at ages of 25-65 years. When access to US Food and Drug Administration-approved primary HPV testing is not available, the ACS offers cotesting or cytology as acceptable alternative strategies but suggests that these testing modalities may be excluded from future iterations of the guidelines. The ASCCP recognizes the benefits and risks of primary HPV cervical cancer screening while acknowledging the barriers to widespread adoption, including implementation issues, the impact of limited HPV vaccination in the United States, and inclusion of populations who may not be well represented on primary HPV screening trials, such as underrepresented minorities. The ASCCP endorses the 2018 US Preventive Services Task Force Recommendation Statement and supports the ACS cervical cancer screening guidelines. Most importantly, the ASCCP endorses any cervical cancer screening for secondary prevention of cervical cancer and recommends interventions that improve screening for those who are underscreened or unscreened.

RESUMO

We examined whether automated visual evaluation (AVE), a deep learning computer application for cervical cancer screening, can be used on cervix images taken by a contemporary smartphone camera. A large number of cervix images acquired by the commercial MobileODT EVA system were filtered for acceptable visual quality and then 7587 filtered images from 3221 women were annotated by a group of gynecologic oncologists (so the gold standard is an expert impression, not histopathology). We tested and analyzed on multiple random splits of the images using two deep learning, object detection networks. For all the receiver operating characteristics curves, the area under the curve values for the discrimination of the most likely precancer cases from least likely cases (most likely controls) were above 0.90. These results showed that AVE can classify cervix images with confidence scores that are strongly associated with expert evaluations of severity for the same images. The results on a small subset of images that have histopathologic diagnoses further supported the capability of AVE for predicting cervical precancer. We examined the associations of AVE severity score with gynecologic oncologist impression at all regions where we had a sufficient number of cases and controls, and the influence of a woman's age. The method was found generally resilient to regional variation in the appearance of the cervix. This work suggests that using AVE on smartphones could be a useful adjunct to health-worker visual assessment with acetic acid, a cervical cancer screening method commonly used in low- and middle-resource settings.

RESUMO

GOALS: We investigated the long-term efficacy and safety of fecal microbiota transplant (FMT) for the treatment of recurrent Clostridioides difficile infection (rCDI). BACKGROUND: FMT has emerged as a promising therapy for patients with rCDI unresponsive to standard medical therapy, though long-term efficacy and safety data are scarce. MATERIALS AND METHODS: A multicenter retrospective study was performed on patients treated with FMT for rCDI with ≥6 months of clinical follow-up post-FMT. Patients were contacted to document sustained efficacy, potential adverse events, and antibiotic exposure. The electronic medical record was reviewed to confirm patient-reported outcomes and obtain additional data. The primary outcome was sustained cure, as defined by the absence of Clostridioides difficile infection (CDI) at any timepoint after FMT. RESULTS: Of 528 patients treated, 207 were successfully contacted. The mean follow-up post-FMT was 34 (range: 6 to 84) months. One hundred fifty-seven patients (75.8%) reported sustained cure at the time of follow-up. One hundred patients (48%) reported the use of antibiotics for non-CDI indications post-FMT, of whom 11 (11%) had experienced CDI post-FMT. Fifty-two of the original 528 patients (9.8%) treated with FMT had died at the time of follow-up contact; none were felt attributable to the procedure. New medical conditions or diagnoses post-FMT were reported in 105 patients (50.5%). Fifteen reported improvement post-FMT in previously diagnosed medical conditions. CONCLUSIONS: In this largest and longest study to date on efficacy and safety after FMT for treatment of rCDI, we found that the majority of patients experienced long-term cure. Although a number of new conditions developed post-FMT, there was no clustering of diseases associated with dysbiosis.

RESUMO

BACKGROUND: Recurrent Clostridioides difficile infection (CDI) is a major public health threat. While clinical prediction tools exist, they do not incorporate the newest Infectious Diseases Society of America guidelines. METHODS: This was a prospective longitudinal study of patients experiencing their first episode of uncomplicated CDI. Patients were followed from diagnosis through 8 weeks post-completion of their anti-CDI therapy to assess recurrence. Stool was collected at diagnosis and weekly for 8 weeks following treatment. Recurrence was defined as diarrhea as well as a positive stool test by toxin EIA (EIA) for C. difficile. Fisher's exact test for binary variables and Student's t test for continuous variables were performed. Cox regression was performed to assess for predictors of CDI recurrence. RESULTS: Seventy-five patients were enrolled between August 1, 2015, and September 1, 2018. Mean age 58.1 years ± 15.5, 69.3% female, 74.7% were white, 11.3% had baseline irritable bowel syndrome, and 54.7% were actively using PPIs. Over the 8-week follow-up period, 22 patients developed a confirmed CDI recurrence. Univariate predictors of recurrence included treatment with metronidazole (40.9% vs 15.1%, p = 0.03), initially diagnosis by EIA (77.3% vs 43.4%, p = 0.007) and platelet count (206 ± 72.1 vs 270.9 ± 114.8, p = 0.03). A Cox regression model revealed primary diagnosis by EIA (HR 3.39, 95% CI 1.23, 9.31, p = 0.018) and treatment with metronidazole (HR 3.27 95% CI 1.31-8.19, p = 0.01) remain predictors for CDI recurrence. CONCLUSION: In a large prospective longitudinal cohort of uncomplicated CDI patients, treatment with metronidazole and diagnosis via EIA were the most robust predictors of CDI recurrence.

RESUMO

OBJECTIVE: To examine the association between ovarian conservation and oncologic outcome in surgically-treated young women with early-stage, low-grade endometrial cancer. METHODS: This multicenter retrospective study examined women aged <50 with stage I grade 1-2 endometrioid endometrial cancer who underwent primary surgery with hysterectomy from 2000 to 2014 (US cohort n = 1196, and Japan cohort n = 495). Recurrence patterns, survival, and the presence of a metachronous secondary malignancy were assessed based on ovarian conservation versus oophorectomy. RESULTS: During the study period, the ovarian conservation rate significantly increased in the US cohort from 5.4% to 16.4% (P = 0.020) whereas the rate was unchanged in the Japan cohort (6.3-8.7%, P = 0.787). In the US cohort, ovarian conservation was not associated with disease-free survival (hazard ratio [HR] 0.829, 95% confidence interval [CI] 0.188-3.663, P = 0.805), overall survival (HR not estimated, P = 0.981), or metachronous secondary malignancy (HR 1.787, 95% CI 0.603-5.295, P = 0.295). In the Japan cohort, ovarian conservation was associated with decreased disease-free survival (HR 5.214, 95% CI 1.557-17.464, P = 0.007) and an increased risk of a metachronous secondary malignancy, particularly ovarian cancer (HR 7.119, 95% CI 1.349-37.554, P = 0.021), but was not associated with overall survival (HR not estimated, P = 0.987). Ovarian recurrence or metachronous secondary ovarian cancer occurred after a median time of 5.9 years, and all cases were salvaged. CONCLUSION: Our study suggests that adoption of ovarian conservation in young women with early-stage low-grade endometrial cancer varies by population. Ovarian conservation for young women with early-stage, low-grade endometrial cancer may be potentially associated with increased risks of ovarian recurrence or metachronous secondary ovarian cancer in certain populations; nevertheless, ovarian conservation did not negatively impact overall survival.

RESUMO

BACKGROUND AND OBJECTIVES: To examine association of lympho-vascular space invasion (LVSI) with clinico-pathological factors and to evaluate survival of women with low-grade serous ovarian carcinoma containing areas of LVSI. METHODS: This is a multicenter retrospective study examining consecutive cases of surgically treated stage I-IV low-grade serous ovarian carcinoma (n = 178). Archived histopathology slides for the ovarian tumors were reviewed, and LVSI was scored as present or absent. LVSI status was correlated to clinico-pathological findings and survival outcome. RESULTS: LVSI was seen in 79 cases (44.4%, 95% confidence interval [CI] 37.1-51.7). LVSI was associated with increased risk of omental metastasis (87.0% vs 64.9%, odds ratio [OR] 3.62, P = 0.001), high pelvic lymph node ratio (median 12.9% vs 0%, P = 0.012), and malignant ascites (49.3% vs 32.6%, OR 2.01, P = 0.035). On multivariable analysis, controlling for age, stage, and cytoreductive status, presence of LVSI in the ovarian tumor remained an independent predictor for decreased progression-free survival (5-year rates 21.0% vs 35.7%, adjusted-hazard ratio 1.57, 95%CI 1.06-2.34, P = 0.026). LVSI was significantly associated with increased risk of recurrence in lymph nodes (OR 2.62, 95%CI 1.08-6.35, P = 0.047). CONCLUSION: LVSI in the ovarian tumor is associated with adverse clinico-pathological characteristics and decreased progression-free survival in women with low-grade serous ovarian carcinoma.

RESUMO

OBJECTIVE: This study aimed to identify the hormonal receptor status in uterine adenosarcoma (AS) and uterine AS with sarcomatous overgrowth (AS + SO), including those with high-grade histologic features (nuclear pleomorphism, atypical mitoses, necrosis), with or without heterologous elements. Estrogen receptor (ER) status, including estrogen receptor α (ERα), estrogen receptor ß (ERß), and G protein-coupled estrogen receptor (GPER), and progesterone receptor (PgR) status were examined. METHODS: From August 2001 to November 2013, 11 patients with histologic diagnosis of uterine AS were identified. Tumor tissue sections were stained for ERα, ERß, GPER, and PgR and examined both for percentage of overall cells stained and for intensity of staining. Descriptive statistics were calculated using clinicopathologic data abstracted from the medical record. RESULTS: Eight cases of AS and 3 cases of AS with high-grade features were identified. Seven of 8 tumor samples of AS showed strong or moderate intensity immunostaining for ERα; all AS + SO tumor samples showed minimal to no immunoreactivity for ERα. There was a significant decrease in ERα H scores in high-grade tumors when compared with AS (P = 0.01). Lower PgR H scores were observed in high-grade tumors compared with those in AS (P = 0.04). Estrogen receptor ß immunostaining was variable, and GPER immunostaining was absent in the majority of tumor samples. CONCLUSIONS: Higher expression of ERα and PgR was observed in AS when compared with those with AS + SO and high-grade features. Both tumor subtypes showed similar levels of ERß and GPER expression, although significant differences in ERß and GPER expression were not detected. In contrast to our previous findings in uterine carcinosarcoma, ERs ERß and GPER do not seem to play a significant role in AS in this study.

RESUMO

OBJECTIVE: Synchronous endometrial and ovarian cancer with endometrioid histology at two cancer sites typically presents with early-stage disease and is thought to have a good prognosis. We examined the survival of women with early-stage endometrioid endometrial cancer who had synchronous early-stage endometrioid ovarian cancer. METHODS: This is a retrospective case-control study examining the Surveillance, Epidemiology, and End Result Program between 1973 and 2013. Survival of women with stage I endometrioid endometrial cancer with stage I endometrioid ovarian cancer (n=839) were compared to women with stage I endometrioid endometrial cancer without synchronous ovarian cancer (n=123,692) after propensity score matching. RESULTS: Women with synchronous stage I endometrioid ovarian cancer were more likely to be diagnosed recently, be younger, have stage IA disease, grade 1 tumors, to have undergone lymphadenectomy, and were less likely to receive radiotherapy compared to those without synchronous ovarian cancer (all, P<0.001). In a propensity score matched model, the presence of synchronous ovarian cancer was not associated with endometrial cancer-specific survival (10-year rates 96.0% versus 95.3%, P=0.97) or overall survival (85.6% versus 87.2%, P=0.10). Among tumors with concordant grades at the two cancer sites, survival was similar regardless of presence of synchronous ovarian tumors (grade 1 tumors, 10-year rate for overall survival, 88.2% versus 89.1%, P=0.40; and grade 2 tumors, 84.0% versus 85.8%, P=0.78). CONCLUSION: Women with stage I endometrioid endometrial cancer with synchronous stage I endometrioid ovarian cancer have a survival outcome similar to those with stage I endometrioid endometrial cancer without synchronous ovarian cancer.

RESUMO

INTRODUCTION: Cervical cytology remains a critical screening tool for cervical cancer. While various factors can influence cytology quality, the effect of lubricant type used during specimen collection has been previously studied with inconclusive results. This study aimed to evaluate the impact of surgical lubricant on cervical cytology results and elucidate risk factors associated with unsatisfactory results. We hypothesized that switching from a carbomer-containing lubricant to a noncarbomer, water-soluble lubricant would improve specimen adequacy in cervical cytology. MATERIALS AND METHODS: A retrospective chart review was performed examining patient cytologic results from January to December 2017 at a single academic institution. After historical rates of unsatisfactory cytology were higher than acceptable standards, the practice changed lubricant formulation from a carbomer containing lubricant to a noncarbomer, water soluble lubricant. Demographic data and treatment characteristics were collected for eligible patients. Matched analysis was performed to examine factors associated with an unsatisfactory cytology result. RESULTS: After the change in lubricant, there was a significant decline in the rates of unsatisfactory cytology from 9.6% to 5.7%, P = 0.01. This decline was also observed when patients were matched based on menopausal status, personal history of gynecologic malignancy, pregnancy status, and cytology specimen type (10.0% to 4.8%, P = 0.001). CONCLUSIONS: Change in lubricant from a carbomer containing to noncarbomer, water soluble product was associated with a statistically significant decline in the rates of unsatisfactory cytology. Although prior data have had mixed results as to the etiology of unsatisfactory cytology, we feel that this directly contributed to the high rates observed at our institution.

RESUMO

Background: The HPV-automated visual evaluation (PAVE) Study is an extensive, multinational initiative designed to advance cervical cancer prevention in resource-constrained regions. Cervical cancer disproportionally affects regions with limited access to preventive measures. PAVE aims to assess a novel screening-triage-treatment strategy integrating self-sampled HPV testing, deep-learning-based automated visual evaluation (AVE), and targeted therapies. Methods: Phase 1 efficacy involves screening up to 100,000 women aged 25-49 across nine countries, using self-collected vaginal samples for hierarchical HPV evaluation: HPV16, else HPV18/45, else HPV31/33/35/52/58, else HPV39/51/56/59/68 else negative. HPV-positive individuals undergo further evaluation, including pelvic exams, cervical imaging, and biopsies. AVE algorithms analyze images, assigning risk scores for precancer, validated against histologic high-grade precancer. Phase 1, however, does not integrate AVE results into patient management, contrasting them with local standard care.Phase 2 effectiveness focuses on deploying AVE software and HPV genotype data in real-time clinical decision-making, evaluating feasibility, acceptability, cost-effectiveness, and health communication of the PAVE strategy in practice. Results: Currently, sites have commenced fieldwork, and conclusive results are pending. Conclusions: The study aspires to validate a screen-triage-treat protocol utilizing innovative biomarkers to deliver an accurate, feasible, and cost-effective strategy for cervical cancer prevention in resource-limited areas. Should the study validate PAVE, its broader implementation could be recommended, potentially expanding cervical cancer prevention worldwide. Funding: The consortial sites are responsible for their own study costs. Research equipment and supplies, and the NCI-affiliated staff are funded by the National Cancer Institute Intramural Research Program including supplemental funding from the Cancer Cures Moonshot Initiative. No commercial support was obtained. Brian Befano was supported by NCI/ NIH under Grant T32CA09168.
