Weekly topical treatment with imiquimod is effective in promoting regression of cervical high-grade squamous intraepithelial lesions.

BACKGROUND: Advances in radiotherapy (RT) have led to improved oncologic outcomes for women with gynecologic cancers; however, the long-term effects and survivorship implications need further evaluation. The purpose of this study was to determine the incidence of pelvic fractures and changes in bone mineral density (BMD) after pelvic RT. METHODS: Two hundred thirty-nine women who had pelvic RT for cervical, endometrial, or vaginal cancer between 2008 and 2015 were prospectively studied. BMD scans and biomarkers of bone turnover were obtained at the baseline and 3 months, 1 year, and 2 years after RT. Imaging studies were assessed for pelvic fractures for up to 5 years. Patients with osteopenia, osteoporosis, or pelvic fractures at any point were referred to the endocrinology service for evaluation and treatment. RESULTS: The median age at diagnosis was 51 years; 132 patients (56%) were menopausal. The primary diagnoses were cervical (63.6%), endometrial (30.5%), and vaginal cancer (5.9%). Sixteen patients (7.8%; 95% confidence interval, 4.5%-12.4%) had pelvic fractures with actuarial rates of 3.6%, 12.7%, and 15.7% at 1, 2, and 3 years, respectively. Fractures were associated with baseline osteoporosis (P < .001), higher baseline bone-specific alkaline phosphatase (P < .001), and older age (P = .007). The proportion of patients with osteopenia/osteoporosis increased from 50% at the baseline to 58%, 59%, and 70% at 3 months, 1 year, and 2 years, respectively. CONCLUSIONS: A high proportion of women had significant decreases in BMD after pelvic RT, with 7.8% diagnosed with a pelvic fracture. BMD screening and pharmacologic intervention should be strongly considered for these high-risk women.

Background: To estimate the prevalence of anal dysplasia in women with high-grade dysplasia or carcinoma of the cervix, vagina or vulva. Methods:In this cross-sectional study, participants underwent anal cytology, anal HPV testing with Cervista HPV16/18 and high-resolution anoscopy (HRA). Patients with HSIL (high-grade squamous cell intraepithelial lesion) or greater on anal cytology or anal biopsy were referred to a colorectal surgery specialist for further evaluation.Results: Seventy-five women were enrolled in the study, including 47 with cervical (cervix group), 10 with vaginal (vagina group), 15 with vulvar (vulva group), 1 with cervical and vaginal, and 2 with vulvar and vaginal disease. The median age in the cervix group (40 years (range 26-69)) was substantially younger than in the vagina (60 years (38-69)) and the vulva (59 years (36-75)) groups. Anal HSIL based on composite endpoints of the most severe cytology or histology result was diagnosed in 6 patients (8.0%). Anal cytology revealed HSIL in 2 (2.7%), atypical squamous cells of undetermined significance (ASCUS) in 12 (16.0%), low-grade squamous cell intraepithelial lesion (LSIL) in 2 (2.7%), and was normal in 59 (78.7%) patients. Anal HPV16/18 test was positive in 15 (20.0%), negative in 48 (64.0%) and insufficient in 12 (16.0%) patients. Of the 6 women with high-grade anal dysplasia, three (50%) had a positive anal HPV16/18 test. No case of anal cancer was observed. Conclusion:Our results suggest that the prevalence of anal HSIL is elevated among women with HPV-related lower genital tract dysplasia or cancer. To further support the inclusion of this highrisk group into screening guidelines for anal dysplasia, further studies are necessary to determine what screening strategy is suited to this population.

We conducted a prospective evaluation of the diagnostic performance of high-resolution microendoscopy (HRME) to detect cervical intraepithelial neoplasia (CIN) in women with abnormal screening tests. Study participants underwent colposcopy, HRME and cervical biopsy. The prospective diagnostic performance of HRME using an automated morphologic image analysis algorithm was compared to that of colposcopy using histopathologic detection of CIN as the gold standard. To assess the potential to further improve performance of HRME image analysis, we also conducted a retrospective analysis assessing performance of a multi-task convolutional neural network to segment and classify HRME images. One thousand four hundred eighty-six subjects completed the study; 435 (29%) subjects had CIN Grade 2 or more severe (CIN2+) diagnosis. HRME with morphologic image analysis for detection of CIN Grade 3 or more severe diagnoses (CIN3+) was similarly sensitive (95.6% vs 96.2%, P = .81) and specific (56.6% vs 58.7%, P = .18) as colposcopy. HRME with morphologic image analysis for detection of CIN2+ was slightly less sensitive (91.7% vs 95.6%, P < .01) and specific (59.7% vs 63.4%, P = .02) than colposcopy. Images from 870 subjects were used to train a multi-task convolutional neural network-based algorithm and images from the remaining 616 were used to validate its performance. There were no significant differences in the sensitivity and specificity of HRME with neural network analysis vs colposcopy for detection of CIN2+ or CIN3+.Using a neural network-based algorithm, HRME has comparable sensitivity and specificity to colposcopy for detection of CIN2+. HRME could provide a low-cost, point-of-care alternative to colposcopy and biopsy in the prevention of cervical cancer.
