RESUMO
OBJECTIVE: Around 70% of vaginal cancers and 40-50% of vulvar cancers are attributable to human papillomavirus (HPV). Globally the burden of these diseases is estimated to grow due to the increasing HPV prevalence and rapidly aging global population. We aimed to examine if HPV screening for cervical cancer has an additional beneficial effect in preventing vaginal and vulvar cancers. To assess this, we used long-term follow-up data from the Finnish randomized HPV screening trial. METHODS: Between 2003 and 2008, over 236,000 women were individually randomized (1:1) to primary HPV or cytology screening in Southern Finland. We followed this cohort up to the year 2020. To compare the study arms, we calculated site-specific and pooled incidence rate ratios (IRRs) and mortality rate ratios (MRRs) for vaginal and vulvar cancers using Poisson regression. RESULTS: During 3,5 million person-years of follow-up, the IRR for vaginal cancer in the HPV arm compared to the cytology arm was 0.40 (95% CI 0.17-0.88) and the corresponding MRR was 0.74 (95% 0.21-2.24). The corresponding IRR for vulvar cancer was 0.73 (95% 0.50-1.08) and the MRR was 0.64 (95% 0.23-1.62). The pooled IRR was 0.67 (95% 0.47 ̶ 0.95) and MRR 0.67 (95% 0.31 ̶ 1.37). CONCLUSION: We found lower incidence of vaginal cancers with HPV screening compared to cytology screening. To validate our results, we recommend analyzing data on vaginal and vulvar cancers also from other HPV screening studies.

To summarize the distribution of types of human papillomavirus (HPV) associated with HPV-related diseases and investigate the potential causes of high prevalence of HPV 52 and 58 by summarizing the prevalence of lineages, sub-lineages, and mutations among Chinese women. We searched PubMed, EMBASE, CNKI, and WanFang from January, 2012 to June, 2023 to identify all the eligible studies. We excluded patients who had received HPV vaccinations. Data were summarized in tables and cloud/rain maps. A total of 102 studies reporting HPV distribution and 15 studies reporting HPV52/HPV58 variants were extracted. Among Chinese women, the top five prevalent HPV types associated with cervical cancer (CC) were HPV16, 18, 58, 52, and 33. In patients with vaginal cancers and precancerous lesions, the most common HPV types were 16 and 52 followed by 58. For women with condyloma acuminatum (CA), the most common HPV types were 11 and 6. In Chinese women with HPV infection, lineage B was the most prominently identified for HPV52, and lineage A was the most common for HPV58. In addition to HPV types 16, which is prevalent worldwide, our findings revealed the unique high prevalence of HPV 52/58 among Chinese women with HPV-related diseases. HPV 52 variants were predominantly biased toward lineage B and sub-lineage B2, and HPV 58 variants were strongly biased toward lineage A and sub-lineage A1. Further investigations on the association between the high prevalent lineage and sub-lineage in HPV 52/58 and the risk of cancer risk are needed. Our findings underscore the importance of vaccination with the nine-valent HPV vaccine in China.

PURPOSE: This study aimed to explore the clinical characteristics and risk factors associated with cervical intraepithelial neoplasia (CIN) when coexisting with vaginal intraepithelial neoplasia (VAIN). METHODS: We analyzed the clinical data of 212 patients diagnosed with CIN, including 50 patients with concurrent VAIN. The groups were compared to identify distinct clinical features and independent risk factors for the co-occurrence of CIN and VAIN, using logistic regression analysis. RESULTS: Patients with both CIN and VAIN had a median age of 57, significantly older than the 41-year median age of patients with CIN only (P < 0.05). A higher prevalence of HPV infection (98.0%) was observed in the CIN and VAIN group, with a notable rate of multiple HPV infections (67.3%) compared to the CIN-only group (P < 0.05). Educational levels were significantly lower in the combined CIN and VAIN group (P < 0.05). HPV16, 33, and 52 were identified as significant types for single and multiple infections. Multivariate analysis confirmed age as an independent risk factor for CIN with VAIN (P < 0.05). VAIN3 patients were more likely to exhibit HSIL and ASC-H, whereas VAIN1 cases tended to correspond with ASCUS and LSIL diagnoses. CONCLUSION: The co-occurrence of CIN and VAIN is significantly influenced by patient age and educational level. The findings advocate for more diligent vaginal examination during colposcopy in older patients, particularly those with multiple HPV infections and cytological abnormalities, to enhance the early detection of vaginal lesions and prevent missed diagnoses and treatments. Additionally, the high prevalence of HPV infection, especially with certain types, underscores the importance of HPV monitoring in this patient population.

Human papillomavirus (HPV) proteins may elicit antibody responses in the process toward HPV-related malignancy. However, HPV seroepidemiology in noncervical HPV-related cancers remains poorly understood, particularly in populations with a high prevalence of human immunodeficiency virus (HIV). Using a glutathione S-transferase-based multiplex serology assay, antibodies against E6, E7 and L1 proteins of HPV16 and HPV18 were measured in sera of 535 cases of noncervical HPV-related cancers (anal (n = 104), vulval (n = 211), vaginal (n = 49), penile (n = 37) and oropharyngeal (n = 134)) and 6651 non-infection-related cancer controls, from the Johannesburg Cancer Study that recruited Black South African with newly diagnosed cancer between 1995 and 2016. Logistic and Poisson regression models were used to calculate adjusted odds ratios (aOR) and prevalence ratios (aPR) and 95% confidence intervals (CI) in cases versus controls. HPV16 E6 was more strongly associated with noncervical HPV-related cancers than HPV16 L1 or E7, or HPV18 proteins: anal (females (HPV16 E6 aOR = 11.50;95%CI:6.0-22.2), males (aOR = 10.12;95%CI:4.9-20.8), vulval (aOR = 11.69;95%CI:7.9-17.2), vaginal (aOR = 10.26;95%CI:5.0-21), penile (aOR = 18.95;95%CI:8.9-40), and oropharyngeal (females (aOR = 8.95;95%CI:2.9-27.5), males (aOR = 3.49;95%CI:1.8-7.0)) cancers. HPV16-E6 seropositivity ranged from 24.0% to 35.1% in anal, vulval, vaginal and penile cancer but was significantly lower (11.2%) in oropharyngeal cancer. After adjustment for HIV, prevalence of which increased from 22.2% in 1995-2005 to 54.1% in 2010-2016, HPV16 E6 seropositivity increased by period of diagnosis (aPR for 2010-2016 vs. 1995-2006 = 1.84;95%CI:1.1-3.0). Assuming HPV16 E6 seroprevalence reflects HPV attributable fraction, the proportion of certain noncervical-HPV-related cancers caused by HPV is increasing over time in South Africa. This is expected to be driven by the increasing influence of HIV.

High-risk human papillomavirus (hrHPV) is the cause of virtually all cervical cancers, most vaginal and anal cancers, and some vulvar cancer cases. With HPV testing becoming the primary screening method for cervical cancer, understanding the link between cervical hrHPV infection and the risk of other anogenital cancers is crucial. We assessed the risk of vulvar, vaginal and anal cancer and precancer (VIN2+, VaIN2+ and AIN2+) in a prospective cohort study including 455,349 women who underwent cervical hrHPV testing in Denmark from 2005 to 2020. We employed Cox proportional hazard models, adjusting for age, calendar year and HPV vaccination status, and estimated hazard ratios (HRs) and 95% confidence intervals (CI). We used the Aalen Johansen estimator to calculate the absolute risks of VIN2+, VaIN2+ and AIN2+. In total, 15% of the women were hrHPV positive at baseline. A positive cervical hrHPV test was associated with increased incidence of vulvar, vaginal and anal squamous cell carcinoma (SCC). Five-year risk estimates of VIN2+, VaIN2+ and AIN2+ among hrHPV-positive women (0.45%, 0.14% and 0.12%) were higher than among hrHPV-negative women (0.14%, 0.01% and 0.05%). Particularly high risk was observed among the hrHPV-positive women of the oldest age, with a history of anogenital precancer and those not HPV vaccinated. In conclusion, our study confirms the association between cervical hrHPV infection and non-cervical anogenital precancers and cancers. Currently, no established risk threshold or guidelines for follow-up. As HPV testing becomes the primary method for cervical cancer screening, future data will help define high-risk groups and acceptable risk thresholds.

BACKGROUND: To date, few studies on the factors related to vaginal intraepithelial neoplasia (VaIN) have been published. In this study, we aimed to analyze the features of VaIN and identify underlying risk factors. METHODS: Patients with VaIN or vaginitis histologically confirmed at the Industrial Street Branch of Chengdu Women's and Children's Central Hospital from July 2020 to December 2021 were included. We statistically analyzed their baseline clinical characteristics, human papillomavirus (HPV) infection status, cytology results, and pathology results. Categorical indicators were analyzed using the chi-square test or Fisher's exact test, as appropriate. Differences were considered to be statistically different with p < 0.05. RESULTS: A total of 62 patients with VaIN (mean age: 39.06 ± 11.66 years) and 32 with vaginitis (mean age: 41.13 ± 13.43 years) were included. Synchronous cervical intraepithelial neoplasia (CIN) was histologically identified in 46 (74.2%) patients with VaIN and 7 (21.9%) with vaginitis (p < 0.001). Low-grade squamous intraepithelial lesions (LSILs) and atypical squamous cells of undetermined significance (ASC-US) were the most frequent cytological abnormalities in both groups. Patients with VaIN only (62.5%) were more likely to be negative for intraepithelial lesion or malignancy than patients with synchronous CIN (32.6%; p = 0.036). No statistically significant difference in HPV infection was noted between patients with VaIN and those with vaginitis (p = 0.439). The most prevalent HPV genotype in patients with VaIN or vaginitis was HPV16, whereas both HPV58 and HPV16 were the most common in patients with concurrent CIN. CONCLUSIONS: Attention should be paid to HPV16- and HPV58-positive patients with cytological abnormalities such as ASC-US and LSILs (especially with synchronous CIN) to avoid misdiagnosis or underdiagnosis and to facilitate early interventions for VaIN.

OBJECTIVES: We aimed to evaluate the risk of cervical and vaginal clear cell adenocarcinoma (CCA) in women, aged 50 years or more, exposed in utero to diethylstilbestrol (DES) and contribute to a reevaluation of the recommendations for cervical and vaginal cancer and pre-cancer screening for these women. METHODS: We carried out a retrospective review for patients received in a cancer institute. Two cohorts were consecutively studied, the first from 1970 to 2003 and the second from 2004 to 2021, and then linked. RESULTS: During the first period, we observed 61 CCA cases, with a mean age at diagnosis of 23 years (7-42), 36 (59%) following DES exposure in utero. During the second period, we found 27 cases, with one case of DES exposure (4%) for a women diagnosed at the age of 40 years. The mean age of the second cohort was 38 years (14-79). For the seven women aged 50 years or more at the time of CCA diagnosis, DES exposure was excluded for five and considered unlikely for the other two. CONCLUSION: In total, 88 cases of cervical or vaginal CCA were observed over a period of 51 years in a cancer center. The 37 cases associated with DES exposure represented approximatively one third of the CCA related to DES expected in France. DES exposure was improbable for the seven cases of CCA for women aged 50 years or more. These results do not support the hypothesis of late cervical or vaginal CCA in women exposed to DES in utero and indicate the need for larger multicentric studies. For the present, we propose specific screening for women exposed to DES in utero in terms of : 1) methods: association of cytology and hrHPV testing, with cervical and vaginal sampling, 2) timing : annual, or without exceeding a three-year interval, continuing after 65 years of age and after hysterectomy.

OBJECTIVE: The aim of this study was to analyze trends in the incidence of vaginal cancer in France over a 28-year period and to present survival for recently-diagnosed women. METHODS: French cancer registries provided data on invasive vaginal cancers diagnosed from 1990 to 2015 and followed up through June 2018. Trends in incidence were analyzed using a Poisson model with a bidimensional penalized spline of age and year at diagnosis. Net survival analysis was restricted to recently-diagnosed cases (2010-2015) and used a novel approach based on a bidimensional penalized spline of age and time-since-diagnosis to model excess mortality hazard. RESULTS: With 162 new cases estimated in France in 2018, vaginal cancer represented 0.9 % of genital cancers in French women. In 2018, the world population age-standardized incidence rate was 0.2 per 100,000 person-years, median age at diagnosis was 75 years. The standardized incidence rate decreased significantly by 3 % per year (95 % CI, -3.8; -2.2) between 1990 and 2018 (0.4 cases per 100,000 person-year in 1990, vs 0.2 in 2018). Age-standardized net survival at 1 and 5 years after diagnosis was respectively 74 % and 45 %. CONCLUSIONS: This study confirms that vaginal cancer is still a rare malignancy in France with 5-year net survival that remains low. We observed a consistent decrease in the incidence rate between 1990 and 2018. It may be too early to attribute these trends to a positive impact of vaccination campaigns against hrHPV infection, since vaginal cancer mainly affects older women and HPV vaccination has only been available since the early 2000s, and only targets young girls.

OBJECTIVES: Women exposed to diethylstilbestrol (DES) in utero have an increased risk of clear cell adenocarcinoma of the lower genital tract, requiring lifelong cervical and vaginal cancer screening. We examined the incidence of DES-related cancers in postmenopausal women 50 years and older. MATERIALS AND METHODS: We conducted a retrospective chart review of patients 50 years and older exposed to DES in utero who received care at our institution. Patients were identified using billing codes and/or searching through the electronic record for the word DES. With this 2-pronged approach, we reviewed a total of 503 charts with confirmed DES exposure to identify gynecologic cancer occurrence. RESULTS: Within the 503 selected charts, 28 cases of gynecologic cancer occurrence were identified. Ten patients had cervical cancer and one patient had vaginal cancer. Only 1 woman of 503 developed a DES-related cervical or vaginal malignancy after age 50 years. No patients were diagnosed with cervical or vaginal cancer after age 65 years. CONCLUSIONS: Diethylstilbestrol-related malignancies are rare in those older than 50 years. Current cervical cancer screening guidelines recommend cessation of screening in an average risk, adequately screened patient at age 65 years, but patients exposed to DES have historically received lifelong screening. However, we found no cases of cervical or vaginal cancer related to DES after age 65 years, suggesting that screening recommendations could be changed for these patients to align with current screening guidelines.

Objectives: The race, age, and region-stratified incidence of vulvar (VUC) and vaginal (VAC) cancers with different histology were unclear. Methods: Data was retrieved from the United States Cancer Statistics database. Average annual percent change (AAPC) and incidence rate ratio (IRR) were calculated. Results: Overall, VUC incidence increased from 18.3 (per 1,000,000 woman-years) to 19.6, but VAC incidence decreased from 5.6 to 4.4. VUC squamous cell carcinoma (SCC) incidence increased (AAPC, 0.96; 95% CI, 0.66-1.25), VUC adenocarcinoma (ADE) incidence stabilized (AAPC, -0.24; 95% CI, -1.44 to 0.98), and VUC other malignancies (OM) incidence decreased (AAPC, -1.31; 95% CI, -2.58 to -0.02). While VAC incidence decreased for any histology (AAPC, -0.63; 95% CI, -1.03 to -0.22; AAPC, -1.60; 95% CI, -2.80 to -0.39; and AAPC, -1.57; 95% CI, -2.24 to -0.89 for SCC, ADE, and OM). Similar trends were observed in most of the stratifications. Conclusion: VUC and VAC incidences varied by histology overall and within stratifications by race, age, and region. The incidence decreased for VUC and VAC with all histologies, except for the increasing VUC SCC incidence.

PURPOSE: Women exposed to diethylstilbestrol (DES) in utero were at elevated risk of clear-cell adenocarcinoma of the vagina and cervix (CCA) as young women. Previous research suggested that this elevated risk of CCA may persist into adulthood. We extended a published analysis to measure CCA risk as these women aged. METHODS: Standardized incidence ratios (SIR) compared CCA risk among women born from 1947 through 1971 (the DES-era) to CCA risk among the comparison group of women born prior to 1947, using registry data that covered the US population. RESULTS: Incidence rates of CCA among both cohorts increased with age. Among the DES-era birth cohort, higher rates of CCA were observed across all age groups except 55-59 years. SIR estimates had wide confidence intervals that often included the null value. CONCLUSIONS: Results are consistent with prior research and suggest an elevated risk of CCA in midlife and at older ages among women exposed in utero to DES. These results highlight unresolved issues regarding cancer risk among aging DES daughters and appropriate screening guidance. The examination of population-based cancer surveillance data may be a useful tool for monitoring trends in the incidence of other rare cancers over time among specific birth cohorts.

BACKGROUND: A simple hysterectomy is considered the definitive treatment modality for cervical intraepithelial neoplasia (CIN). However, it is associated with recurrence of vaginal intraepithelial neoplasia (VAIN) of up to 7.4%. We sought to determine recurrence rates of VAIN, in women living with HIV (WLWH) and non-infected women. METHODS: This was a descriptive retrospective review of patients who received a simple hysterectomy for CIN between January 2015 and December 2017 in Pietermaritzburg. RESULTS: Fifty-eight files were reviewed. Forty-two (72.4%) WLWH were seen; amongst those, 76.2% were virally suppressed. Abnormal vault cytology was only seen in patients with CIN grades 2 and 3. The recurrence rates for high-grade squamous intraepithelial lesion (HSIL) were 6.1% and 5.0% at 6 and 12 months, respectively. Human immunodeficiency virus co-infection was associated with 26.2% versus 13.3% of abnormal vault cytology compared to the HIV-negative counterparts (p = 0.164). Virologically suppressed patients had more abnormal cytology (28.1% vs. 0%) compared to the unsuppressed patients. There was a 17.2% and 65.5% loss- to follow-up rates at 6 and 12 months, respectively. Recurrence of premalignant lesions was noted amongst those who had the abdominal approach. CONCLUSION: The recurrence rates were comparable to the previous literature. A 6-month cytology follow-up showed no added benefit. Human immunodeficiency virus co-infection didn't show a statistical significance on the recurrence rates; however, more structured studies are required to address this. Primary health care-based post operative surveillance can be a solution to address high loss to follow-up.

OBJECTIVE: To investigate the clinical, pathological, and genetic characteristics of patients with vaginal melanoma in a nationwide setting. MATERIALS/METHODS: All patients diagnosed with vaginal melanoma from 1980 to 2018 were collected by searching the digital archives of the Danish Registry of Pathology (Patobank). Patient specimens were examined, the histological diagnoses were validated, and targeted next-generation sequencing (NGS) of known frequent hot spots in 163 genes was performed. RESULTS: Fifty-two patients were included. The incidence for primary melanoma of the vagina in the Danish population (5.5 million people) was calculated to be 0.24 cases/million/year from 1980 to 2018. For all patients, the median OS was 17.5 months (95% CI: 13.0-24.0), and the 5-year OS was 19.4% (95% CI: 10.9-34.3). We identified frequent mutations in ATRX (7/25 cases) and TP53 (7/25 cases). Mutations found in TP53 were associated with a significant decrease in OS (p = 0.043), whereas mutations in the ATRX gene alone did not show a significant impact on OS (p = 0.3649). Patients who harbored co-mutations in both ATRX and TP53 showed a significant reduction in OS (p = 0.0081), with a median OS of 9.5 months compared to 20 months in those without the co-mutation. CONCLUSIONS: Vaginal melanoma is a rare disease with a poor prognosis presumably due to vague symptoms and the anatomical location of the disease. Co-mutations in ATRX and TP53 and mutations in TP53 alone were associated with a poor prognosis, and these genes are potentially interesting targets for future therapy.

The incidence of vaginal intraepithelial neoplasia (VAIN) is increasing annually; however, the reported values are likely underestimated. Risk factors for VAIN include advanced age, human papillomavirus (HPV) infection, history of hysterectomy, and simultaneous or previous cervical intraepithelial neoplasia (CIN) or cervical cancer cervical cancer. The most common presentation is abnormal cytology without clinical symptoms. Despite various treatment modalities available, the rate of disease recurrence is high, and its malignant potential has been documented. This study aimed to examine demographic and clinical characteristics and associated treatment outcomes of patients with VAIN. We retrospectively reviewed clinicopathologic data and clinical outcomes of patients diagnosed with VAIN at a single center between January 2010 and December 2017. Overall, 118 patients were included (average age 49.81 ± 9.77 years; range, 26-70 years). The distribution of the histologic grade was as follows: VAIN1, 30.5%; VAIN2, 41.5%; and VAIN3, 28.0%. In total, 97 (82.2%) patients had either prior or simultaneous cervical lesions, CIN (35.6%), or cervical cancer (55, 46.6%). A total of 100 cases (84.7%) were diagnosed using colposcopy and 18 (15.3%) were diagnosed by pathological accident after hysterectomy. Thin-prep cytology test (TCT) results were available for 112 (94.9%) patients, and 111 (94.1%) patients had abnormal cytology findings. Most patients were confirmed as HPV positive (115, 97.5%), and 84 (71.2%) patients were confirmed as positive for high-risk HPV types. Forty-two (35.6%) patients underwent hysterectomy before VAIN diagnosis, and the median interval between hysterectomy and VAIN diagnosis was 26.5 (range: 3-68) months. Most surgical indications were HPV-related diseases (34, 80.9%), such as CIN (8, 19.0%) or cervical cancer (26, 61.9%). Eight patients had no history of cervical lesions. A total of 100 patients underwent initial treatment. During the median follow-up period of 29 (range: 9-96) months, 78 (78%) patients experienced disease remission after initial treatment, 7 (7%) experienced disease recurrence, 10 (10%) had persistent disease, and 5 (5%) had progressive disease. Finally, two patients developed vaginal cancer without death. Colposcopy should be performed before vaginal hysterectomy for VAIN, particularly HPV-related cases. The incidence of VAIN was 20% after hysterectomy owing to non-HPV-related lesions; thus, this part of the screening should not be discontinued. VAIN grade 2,3 and VAIN associated with CIN or cervical cancer are disease types more likely to recur and progress to invasive cancer; active medical intervention is recommended.

BACKGROUND: Rhabdomyosarcoma (RMS) of the female genitourinary tract (FGU-RMS) located at the vagina or uterus is one of the most favorable RMS sites. Little is known about treatment and outcome in infants and relapsed disease (RD). METHODS: Characteristics, treatment, and outcome of 71 children with FGU-RMS registered within five Cooperative Weichteilsarkom Studiengruppe (CWS) trials and one registry (1981-2019) were evaluated. RESULTS: FGU-RMS was diagnosed in 67 patients with localized disease (LD) at a median age of 2.89 years (0.09-18.08). Multimodal treatment consisted of chemotherapy (CHT) (n = 66), secondary surgery (n = 32), and radiotherapy (n = 11). Age at diagnosis ≤12 months was the only significant negative prognostic factor influencing the event-free survival (EFS). Ten-year EFS and overall survival (OS) for infants ≤12 months were 50% and 81%, respectively. In contrast, children with LD >1 year and ≤10 years had a 10-year EFS and OS of 78% and 94% (P = .038), and >10 years of 82% and 88%, respectively (P = .53). Metastatic disease was observed in four patients of which three are alive. RD occurred in five of 12 infants ≤1 year and 10/55 children at a median of 1.38 years (0.53-2.97) after initial diagnosis. Treatment of patients with RD consisted of multimodal treatment (n = 13) or resection only (n = 2). Nine patients (60%) were alive in clinical remission at a median of 7.02 years (1.23-16.72) after diagnosis of RD. CONCLUSION: Infants with FGU-RMS have a higher relapse rate than older children with FGU-RMS, but prognosis is fair.

AIM: The human papilloma virus has been associated with anal, cervical, vaginal, and penile cancers. The primary aim of this population-based study is to determine whether HPV-associated cancers are more commonplace in patients with inflammatory bowel disease (IBD). METHOD: The Hospital Episode Statistics (HES) database from 1997 to 2012, linked with officer for age standardized rates (ASR), were calculated using population data, and Cox regression analysis was used to determine whether IBD patients have poorer survival compared with non-IBD patients. RESULTS: A total of 61,648 patients were included in this study; of these, 837 patients had a preexisting diagnosis of IBD (1.4%). Inflammatory bowel disease patients had a significantly higher ASR of anal cancers than the non-IBD population: 5.5 per 100,000 in the IBD group compared with 1.8 in the non-IBD group. The IBD group was also diagnosed with anal cancers at a younger age (60 years compared with 66 years in the non-IBD group, Pâ <â 0.001). The survival of IBD patients with anal cancer was also poorer than the non-IBD group (hazard ratio, 1.32; 95% confidence interval, 1.15-1.52; Pâ <â 0.001). On average, survival was significantly shorter in the IBD group with anal cancer (46 months) compared with the non-IBD group (61 months, Pâ <â 0.001). Age standardized rates for cervical cancer was significantly higher in the IBD group (5.2 of 100,000) compared with the non-IBD group (4.6 of 100,000 Pâ =â 0.042). CONCLUSION: Patients with IBD have a higher rate of anal cancer compared with the general population. Survival is also worse for anal cancers in the IBD group.

OBJECTIVES: In total, 80,000 women were exposed to diethylstilbestrol (DES) in utero in France (DES daughters) between 1950 and 1977. After having been dominated by the management of infertility and pregnancy accidents, monitoring must adapt to the increased risk of cancer of the cervix and vagina: doubling of the frequency of severe dysplasia and a risk of late clear-cell adenocarcinoma (CCA). Two recent changes in cervical cancer screening in France, the introduction of HPV tests in first-line screening and organized screening, should consider the particular situation of DES daughters. We aimed to assess the compliance of DES daughters with previous recommendations and propose specific screening practices in the new context. METHOD: A non-profit organization carried out a questionnaire survey of its members who were exposed to DES in utero. RESULTS: Among the 570 participants, 64 % had annual PAP tests, 25 % within the last three years, and 11 % more than three years before or never. The reasons for "dropout" were: 1) ignorance of the recommendations by practitioners (38 %) or patients (30 %), 2) fatigue (32 %) or apprehension of the exams (14 %), and 3) difficult access to care: time to get an appointment (26 %), difficulty in finding a doctor (28 %), or cost (6 %). CONCLUSION: These results concern women who were sufficiently aware of the issue to be a member of an association. They are encouraging but show a need to improve the dissemination of information to all "DES daughters" and health professionals. Patient associations can play a growing role in this "rare disease" by addressing patients and healthcare professionals. We propose that screening for these women include an annual screen of not only the cervix, but also the vagina, and that it continues beyond 65 years of age and after hysterectomy, with cytological examination, because ACC is unrelated to HPV.

OBJECTIVES: To investigate the incidence of vaginal intraepithelial neoplasia (VaIN) after total hysterectomy and, subsequently, optimize the follow-up strategy of patients after hysterectomy. METHODS: This retrospective study was conducted on 8581 patients with benign gynecology disease who underwent total hysterectomy in our institution between January 2006 to December 2017, including 834 patients with cervical intraepithelial neoplasia (CIN) and 7747 patients without cervical lesions before hysterectomy. All patients underwent postoperative high-risk human papilloma virus (Hr-HPV) screening and liquid-based cytology test (LCT) as confirmatory tests. Colposcopies were performed if the results of the confirmatory tests were abnormal, and biopsies were performed depending on colposcopy images. The mean follow-up time was 33.8 ± 12.1 months. The relationship among VaIN, CIN, and confirmatory test results was investigated. RESULTS: VaIN was found in 81 patients after hysterectomy (incidence rate, 0.9%). The incidence rates of VaIN in patients with and without CIN history were significantly different (7.3%, 61/834, vs 0.3%, 20/7747; P < 0.05). Compared with patients without CIN history, those with CIN history were more likely to have abnormal LCT results in the postoperative follow-up, especially low-grade squamous intraepithelial lesions or worse (P < 0.001). Patients with high-grade squamous intraepithelial lesions in the LCT have a high VaIN incidence (patients with CIN history, 57.1%; patients without CIN history, 15.1%), and the 2 patients with squamous cell carcinoma or adenocarcinoma (SCC/AC) in the LCT had CIN and VaIN or worse after hysterectomy. The Hr-HPV infection rates after the hysterectomy of patients with and without CIN history were 18.8% (157/834) and 5.4% (419/7747), respectively. The incidences morbidities of VaIN in patients with persistent Hr-HPV infection and in those with and without CIN history were 35.7% and 12.0%, respectively, and were significantly higher than those in patients with negative Hr-HPV (patients with CIN history, 0.7%; patients without CIN history, 0.1%; P = 0.002). The incidence of VaIN in patients with CIN history with HPV-16 infection after hysterectomy was as high as 50%, but in patients without CIN history, the incidences of different Hr-HPV subtypes were not significantly different (P = 0.953). CONCLUSION: Patients with CIN history were more prone to VaIN and SCC after hysterectomy than were patients without CIN history. Patients should be screened thoroughly for cervical and vaginal lesions before hysterectomy. After hysterectomy, patients with CIN history should undergo lifetime annual LCT and HPV screening.

BACKGROUND: Vaginal lesions are rare and of various types in children. Clinical presentation is generally undifferenciated. Histological examination is fundamental to ascertain the nature of the lesion. Regarding tumoral lesions, histological subtypes encountered are radically different from those seen in adults, dominated by stromal benign lesions. OBJECTIVE: The aim of this retrospective study was to describe characteristics and pathological aspects of pediatric vaginal lesions, diagnosed in a single pediatric experienced center. STUDY DESIGN: A database analysis was performed on all vaginal samples of patients under 18 years old received in a pediatric-specialized pathology laboratory of an academic hospital, over a 26-year period. RESULTS: Among 36 vaginal tissue samples reported, a total of 15 tumoral or pseudotumoral processes was recorded. Primitive malignant tumors included embryonal rhabdomyosarcoma (n = 3) and germ-cell tumors, yolk-sac type (n = 2). Benign tumoral or pseudotumoral processes included inflammatory stromal polyps (n = 8), epidermic cyst (n = 1), and benign Müllerian papilloma (n = 1). DISCUSSION: Over 15 primitive vaginal tumors, 1/3 was malignant with embryonal rhabdomyosarcoma being the most common. The remaining 2/3 specimens were benign, with stromal inflammatory lesions being the most commonly observed. Fibro-epithelial polyp is a debated entity, which covers a wide histological spectrum, with varying inflammation and stromal cellularity, raising sometimes the question of the differential diagnosis with rhabdomyosarcoma. Stromal cells morphology along with their immunohistochemical profile suggest their reactive myofibroblastic nature. Pseudotumoral inflammatory lesions display very similar histological findings with these entities. A common pathogenesis beginning with an inflammatory process, potentially accelerated by chronic traumatic factors, could be discussed. CONCLUSION: We confirmed the rarity and the diversity of vaginal lesions in children. Vaginoscopy and biopsy sample should be systematic, given the non-specific presentation of tumoral processes. Myogenin immunostain must be systematic in case of vaginal polypoid mass, in order to rule out malignancy.

OBJECTIVES: The aim of this survey was to evaluate the different surgical approaches for women with high-grade vaginal intraepithelial neoplasia (HG-VaIN) used in 8 hospitals in central and northern Italy in the last 20 years. In particular, the baseline characteristics of the patients and factors potentially leading to excisional treatment rather than ablation were considered. Moreover, the clinical outcome of patients treated for HG-VaIN (disease persistence or recurrence and progression toward invasive vaginal cancer) was analyzed. MATERIALS AND METHODS: The medical records of all women initially diagnosed with HG-VaIN and subsequently treated in 8 Italian hospitals from January 1996 to December 2016 were analyzed in a multicenter retrospective case series. RESULTS: Among the 226 women included, 116 (51.3%) underwent ablative procedures and 110 underwent excisional surgery (48.7%). An ablative procedure was preferred in cases where multiple lesions were found on colposcopic examinations. Physicians decided more frequently to perform excisional procedures in women with menopausal status, high-grade referral cervical cytology, previous hysterectomy for human papillomavirus-related disease, or VaIN 3 on colposcopic-guided biopsy. CONCLUSIONS: The surgical treatment of HG-VaIN should be tailored according to the clinical characteristics of each woman and each lesion. However, in potentially high-risk cases (VaIN 3, previous hysterectomy for human papillomavirus-related disease, and menopausal women) or in those cases in which an occult invasive disease cannot be ruled out, an excisional approach should be preferred.In any case, long-term follow-up is advisable in women treated for HG-VaIN.
