Abstract
This study aimed to analyze the human papillomavirus (HPV) genotype distribution in a large cohort of high-grade vaginal intraepithelial neoplasia (VaIN) (vaginal HSIL, VaIN2/3) patients from two Italian referral centers. We included all patients with histologically confirmed VaIN2/3 from the Department of Surgical Sciences, Sant'Anna Hospital, University of Torino, Torino, Italy, and Ospedale Maggiore della Carità, Novara, Italy, between 2003 and 2022. After the histological evaluation of formalin-fixed paraffin-embedded samples, we performed HPV genotyping with VisionArray HPV Chip 1.0. We detected HPV DNA in 94.4% of VaIN2/3 (168/178), with HPV 16 as the most prevalent genotype, accounting for 51.8% of all infections, 41.2% of VaIN2 and 77.6% of VaIN3 cases. Other frequent genotypes were HPV 58 (8.3%, 10.9% of VaIN2 and 2.0% of VaIN3), HPV 73 (5.4%, 5.0% of VaIN2 and 6.1% of VaIN3), and HPV 31 (5.4%, 6.7% of VaIN2 and 2.0% of VaIN3). 73.2% of VaIN2/3 had a single HPV genotype infection and 26.8% a multiple infection (20.8% a double infection, 4.8% a triple infection, and 1.2% a quadruple infection). Single infection was more frequently present in VaIN3 than VaIN2 (81.6% vs. 69.8%). 69.1% of single infections and 73.3% of multiple infections had one or more genotypes covered by nine-valent HPV vaccine. HPV vaccination is expected to have a large impact on reducing the incidence of vaginal intraepithelial neoplasia.

Abstract
To explore the incidence of abnormal vaginal cytology after total laparoscopic hysterectomy for the treatment of cervical intraepithelial neoplasia 3, we retrospectively analyzed the medical records of patients treated at NHO Shikoku Cancer Center (Japan) in 2014-2019. The cases of 99 patients who underwent a laparoscopic (n=36) or open (n=63) hysterectomy and postoperative follow-up were examined. Abnormal vaginal cytology was detected in 13.9% (5/36) of the laparoscopic-surgery (LS) group and 14.3% (9/63) of the open-surgery (OS) group. A vaginal biopsy was performed at the physicians' discretion; one LS patient and six OS patients were diagnosed with vaginal intraepithelial neoplasia. The cumulative incidence of abnormal vaginal cytology at 3 years post-hysterectomy was 21.4% (LS group) and 20.5% (OS group), a nonsignificant difference. A multivariate analysis showed that age > 50 years was the only independent risk factor for abnormal vaginal cytology among the covariates examined including age; body mass index; histories of vaginal delivery, abdominal surgery, and smoking; and surgical approach (hazard ratio 8.11; 95% confidence interval 1.73-37.98; p=0.01). These results suggest that the occurrence of abnormal vaginal cytology after a hysterectomy may not be influenced by the laparoscopic procedure but is associated with older age.

Abstract
Human papillomavirus (HPV) encompasses a group of viruses that infect the skin and mucous membranes. In the presence of certain factors, persistent infection with high-risk HPVs can trigger a process of neoplastic transformation. Imiquimod is a topical agent that acts as a Toll-like receptor 7/8 agonist, stimulating the innate and adaptive immune system to exert antitumor and antiviral effects. It has been approved for the treatment of various skin conditions, however, its efficacy and safety in the management of HPV-related-neoplasms of the lower genital tract, such as vulvar, vaginal, and cervical neoplasia, are still under investigation. This review summarizes the current evidence on the use of imiquimod for the treatment of HPV-induced lesions of the female lower genital tract, focusing on its indications, mechanisms of action, outcomes, and predictors of response.

Abstract
OBJECTIVE To explore the relationship between infection with human papillomavirus (HPV)-16 and the development of vaginal intraepithelial neoplasia (VaIN). METHODS This is a retrospective study. 78 patients with suspected VaIN admitted to the gynecologic clinic of Affiliated Hospital of Guilin Medical College from August 2016 to December 2020 who were confirmed to have HPV-16 infection by HPV rapid flow-through hybridization method were selected as the research subjects. The copy numbers of HPV-16 early genes E2 and E6 were detected by quantitative real-time PCR amplification to analyze the integration status of the virus. RESULTS The episomal form of HPV-16 exists in all levels of VaIN. As the pathological level of VaIN increased, the episomal form of HPV-16 gradually decreased, and a disruption of the E2 gene became more frequent. However, there was no significant difference between different levels of VaIN (P>0.05). With the increased severity of cytology results, the percentage of the episomal form of HPV-16 decreased from 76.47% in atypical squamous cells of undetermined significance (ASC-US) to 44.44% in the high-grade squamous intraepithelial lesion (HSIL) (χ2 =4.780, P<0.05). However, the integrated form of HPV-16 did not increase significantly as the severity of cytology increased (χ2=2.215, P>0.05). CONCLUSION HPV gene integration may occur before the onset of VaIN. However, the occurrence of HPV-16 integration is not a risk factor leading to the malignant progression of VaIN. An E2 gene disruption is more common in the early events after HPV-16 infection. HPV-16 gene integration may be the main reason for persistent HPV-16 infection.

Abstract
OBJECTIVE To analyze the clinical management, the outcomes, and the trend in hysterectomy rates (HR) in patients who underwent this procedure for cervical intraepithelial neoplasia (CIN). METHODS Multicentric retrospective observational study conducted on 242 patients who underwent hysterectomy for CIN between 2010 and 2020 in nine Italian institutions. Hysterectomy for invasive or micro-invasive neoplasia, sub-total hysterectomy, or trachelectomy were excluded. RESULTS A significant increase in the trend of HR for CIN was recorded (P = 0.002, r = 0.81; C.I. 95%: 0.415-0.949); HR increased from 0.46% in the year 2010 to 3.32% in 2020. The mortality rate was 0.4%, and 5% had operative complications. On definitive histopathology examination, a CIN of any grade was recorded in 71.5% of cases, and an occult invasive cancer in 1.24%. No pathology or CIN1 was found in 26.8% of cases, suggesting over treatment. During follow-up, a vaginal lesion was recorded in 5% of cases. CONCLUSION A significant increase in the number of hysterectomies performed for CIN in the last 10 years was recorded. Hysterectomy for CIN can lead to complications, risk of the onset of vaginal lesions, and risk of overtreatment, and remains, in the first instance, an unacceptable treatment, to be proposed only after adequate counseling.

Abstract
OBJECTIVES Although carbon dioxide laser vaporization is frequently used for treating vaginal intraepithelial neoplasia (VaIN), the optimal depth of epithelial destruction with laser vaporization requires elucidation. We aimed to evaluate VaIN depth and better illustrate epithelial destruction during laser vaporization. MATERIALS AND METHODS We included 246 women diagnosed with VaIN (low-grade VaIN [VaIN 1], 123 women; high-grade VaIN [VaIN 2/3], 123 women) using colposcopy-directed biopsy at our hospital from January 1, 2019, to April 30, 2020. The thickness of the noninvolved epithelium, if available, was determined. All available data, including cytology and histological information, were recorded. The t test and Pearson χ 2 test were used for statistical analysis. Statistical significance was set at p < .05. RESULTS The involved epithelial thicknesses in VaIN 2/3 and VaIN 1 were 0.41 ± 0.21 and 0.40 ± 0.19 mm, respectively, which were both greater than their noninvolved epithelial thickness values (0.17 ± 0.10 and 0.17 ± 0.08 mm, p < .01 and p < .01, respectively). In subgroup comparisons between the VaIN 2/3 and VaIN 1 groups, the involved epithelial thickness did not differ between premenopausal patients, postmenopausal women receiving estrogen, and postmenopausal women who did not receive estrogen ( p > .05). In the VaIN 2/3 group, the lesion thickness in premenopausal was greater than that in postmenopausal women receiving estrogen ( p = .016) and those who were not receiving estrogen ( p = .017). CONCLUSIONS The thickness of VaIN is generally less than 1 mm for women of all ages, except in rare cases of visible lesions with papillary hyperplasia.

Abstract
OBJECTIVES The aim of the study were to identify the risk factors for recurrent vaginal intraepithelial neoplasia (VaIN)1+ and to evaluate the efficacy of laser vaporization in patients who underwent hysterectomy for the treatment of cervical intraepithelial neoplasia (CIN). METHODS Medical records of 374 women who underwent hysterectomy for the treatment of CIN were retrospectively reviewed. Recurrence was defined as VaIN1+ diagnosis by colposcopy-directed biopsy. RESULTS Among 374 patients, 36 (9.6%) had VaIN1+ during a median follow-up of 32 (0-193) months: 13 (3.5%) had VaIN1, 6 (1.6%) VaIN2, 15 (4.0%) VaIN3, and 2 (0.5%) invasive cancer. Multivariate analysis showed that age of greater than 50 years was the only independent risk factor for VaIN1+ recurrence (odds ratio, 3.359; 95% CI, 1.60-7.07; p = .001). Among the 34 patients with VaIN, 21 (61.8%) were treated with laser vaporization and 11 (32.3%) were observed without treatment. Time to second recurrence was longer in the VaIN treated by laser vaporization group than that in the observation group (mean time to subsequent recurrence, 128.7 [95% CI, 101.4-156.0] vs. 41.8 [15.7-67.9] months; p = .003). Moreover, laser vaporization (hazard ratio, 0.125; 95% CI, 0.03-0.59; p = .009) was the only independent good prognostic factor for the second VaIN1+ recurrence. CONCLUSIONS Patients older than 50 years who underwent hysterectomy for the treatment of CIN might be highly at risk of VaIN1+. Laser vaporization is the only independent prognostic factor that might prevent the second VaIN1+ recurrence.

Abstract
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.

Abstract
BACKGROUND Recent data has shown increased rate of vaginal intraepithelial neoplasia (VAIN) in younger individuals. Traditional VAIN treatments exert adverse effects on the anatomy and functions of the vaginas. Topical 5-aminolevulinic acid photodynamic therapy (ALA-PDT) is a novel, non-invasive targeted therapy for intraepithelial lesions. Here, we aimed to investigate the efficacy and safety of ALA-PDT in VAIN with high-risk HPV (HR-HPV) infection. METHODS This study enrolled a total of 82 HR-HPV-positive women diagnosed with VAIN, who were receiving ALA-PDT. The effect of ALA-PDT was evaluated using HPV genotyping and Thinprep cytologic test (TCT). Besides, colposcopy directed biopsies were performed in all patients at 3-month follow-up, and in patients with positive HR-HPV and/or abnormal TCT results during the follow-up period. RESULTS Our data showed that the HPV clearance rate was 53.7% (44/82) at 6-month follow-up and 67.1% (55/82) at 12-month follow-up. Patients with HPV16/18 combined with other HR-HPV (HPV16/18 & other HR-HPV) infection, those with a history of hysterectomy and/or older age were had significantly lower HPV clearance rate. Besides, the lesion complete remission (CR) rate was 90.2% (74/82). These results show that HPV16/18 & other HR-HPV infection was associated with significantly lower CR rates. Throughout the follow-up, 2 cases had persistent lesions (2.4%), 6 cases had partial remission (7.3%), 2 cases recurred (2.7%) but none of the patients had disease progression. CONCLUSIONS Taken together, our data showed that ALA-PDT is an effective, safe, and alternative treatment for VAIN patients with HR-HPV infection. However, the ALA-PDT efficacy was relatively poor in patients with older age, HPV16/18 & other HR-HPV infection and/or those with a history of hysterectomy.

Abstract
Purpose To examine the screening history of vaginal intraepithelial neoplasia (VaIN) and vaginal cancer. Patients and Methods We included women with histologically confirmed VaIN or vaginal cancer by colposcopy-directed biopsy between 1 January 2019 and 31 December 2019. The results of cytology, hrHPV, colposcopic examination and history of hysterectomy were retrospectively analysed. Results A total of 26,432 colposcopies were performed during the study period, among which 2131 women (1835 [86.1%] with VaIN 1; 268 [12.6%] with VaIN 2/3; and 28 [1.3%] with vaginal cancer) were retrospectively studied. hrHPV test positivity was significantly higher than that of cytology for VaIN 1 (84.4% vs 67.3%; P < 0.001) and VaIN 2/3 (92.0% vs 79.9%; P < 0.001) but not for vaginal cancer (84.6% vs 78.6%; P = 0.73). Additionally, the concordance rates for colposcopic impression were 79.5%, 54.5%, and 92.8% for VaIN1, VaIN2/3, and vaginal cancer, respectively. All 372 patients had a history of hysterectomy, and 81.0% (282/348) of indications were related to cervical precancer and cancer. Although cytology test positivity was significantly higher in patients with hysterectomy than in patients without hysterectomy (76.2% vs 67.5%; P < 0.001), cytology combined with hrHPV can help to detect more than 95% of VaIN and vaginal cancer cases in both groups (96.2% for patients with hysterectomy and 96.5% for patients without hysterectomy). Conclusion VaIN and vaginal cancer are not rare diseases. Although cytology was sensitive (67.5%-76.2%) for detecting vaginal lesions regardless of hysterectomy, cytology combined with hrHPV improves detection accuracy up to 95% in both groups.

Abstract
To analyze the distribution of human papillomavirus (HPV) genotype, cytology, and the clinical characteristics of vaginal intraepithelial neoplasia (VaIN). All patients with histological-proven VaIN at West China Second University Hospital, between January 1, 2014, and October 1, 2020, were retrospectively identified. The demographics, medical history, HPV genotype, viral load, and cytology results were retrieved. Standard statistical analyses were conducted. Of 3229 patients included, 42.3% were diagnosed with VaIN 1, 30.3% with VaIN 2% and 27.4% with VaIN 3. Patients with VaIN 3 were the oldest (p < 0.001). The leading HPV genotypes were HPV 16, 52, 58, 53, 56 and 81. The positive rate of HPV 16 was positively correlated with the grade of VaIN and infected most VaIN 3 patients (76.0%). The sensitivities of cytology for VaIN only, concomitant VaIN, and VaIN after hysterectomy were 75.6%, 78.8%, and 82.9%, respectively (p = 0.013), and the sensitivities of HPV were 91.1%, 93.5%, and 91.7%, respectively (p = 0.205). Cotesting improved the sensitivities, up to 96.9%, 97.1%, and 98.1%, respectively. VaIN can occur alone or be concomitant with cervical or vulvar intraepithelial neoplasia. Most of those with VaIN 2/3 are infected with HPV 16. The sensitivity of cytology and HPV testing is non-inferior to that of cervical intraepithelial neoplasia 2+. Therefore, these testings might be helpful in the early detection of VaIN.

Abstract
Vaginal cancer is a rare disease of the lower genital tract. We present the case of a 54-year-old woman with occult vaginal cancer after hysterectomy for cervical intraepithelial neoplasia (CIN) III. Despite persistently negative cytology and colposcopy results, a lesion was finally detected by vagino-recto-abdominal examination and she underwent radical parametrectomy and lymph node dissection. We consider the possibility that transabdominal suturing of the vaginal cuff after hysterectomy may reduce the ability to detect subsequent vaginal lesions, and discuss the benefits of a vaginal suture approach. We recommend that suturing the vagina apex transvaginally instead of transabdominally would benefit patients during follow-up.

Abstract
We present a patient diagnosed with high-grade cervical intraepithelial neoplasia (CIN) combined with macroscopic lesions of the vaginal epithelium. There was no lesion in pelvic magnetic resonance imaging examination, and histopathological examination revealed CIN3 and vaginal intraepithelial neoplasia (VAIN) 3 without invasion. We chose minimally invasive surgery for her and total laparoscopic hysterectomy with partial resection of the vagina was carried out. To determine appropriate surgical margins, vaginal colpotomy was performed. No recurrence of VAIN has been observed to date that passed for 9 months either.

Abstract
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.

Abstract
OBJECTIVE To identify high-risk HPV (hrHPV) genotypes associated with high-grade vaginal intraepithelial neoplasia (VaIN), and evaluate the efficacy of various treatments for high-grade VaIN. METHODS A retrospective review of outcomes among women diagnosed with VaIN after vaginal punch biopsy conducted due to an abnormal Papanicolaou smear or positive test for hrHPV at a hospital in Seoul, Korea, from 2013 to 2018. Logistic regression was used to identify variables associated with abnormal pathologic outcomes. RESULTS Among 389 women included in the study, 58 were diagnosed with high-grade VaIN, including VaIN stage 2 (n = 37), VaIN stage 3 (n = 16), carcinoma in situ of the vagina (n = 3), and squamous carcinoma of the vagina (n = 2). In multivariate logistic regression analysis, risk of high-grade VaIN and cancer was higher among women with abnormal cytology (odds ratio [OR], 1.88; 95% confidence interval [CI], 1.47-2.47), any hrHPV infection (OR, 8.75; 95% CI, 1.14-67.31), HPV16 infection (OR, 5.71; 95% CI, 2.57-12.68), or HPV31 infection (OR, 4.37; 95% CI, 1.45-13.11). CONCLUSION The findings suggest that infection with hrHPV, especially HPV16 and HPV31, is significantly associated with high-grade VaIN. Regarding treatment modalities, ablative or excisional treatments showed good efficacy against pathologic regression of high-grade VaIN.

Abstract
Purpose To evaluate the colposcopic accuracy of the detection of vaginal intraepithelial neoplasia (VaIN) according to the colposcopic terminology for the vagina from the 2011 International Federation of Cervical Pathology and Colposcopy (IFCPC). Methods A total of 467 women who were suspected of having VaIN and underwent colposcopy at Obstetrics and Gynecology Hospital of Fudan University from January to December 2018 were included in this retrospective cohort study. The 2011 IFCPC revised terminology for the vagina was applied, and the agreement between colposcopic diagnosis and vaginal biopsy pathology was analysed. Results Agreement between colposcopy and pathology was 69.16% (kappa=0.437, p<0.001), with 23.34% overestimated and 7.49% underestimated diagnosis for colposcopy. The agreement was the lowest (35.71%) in the high-grade VaIN group, which was significantly different from that of other lesion grade groups (p<0.01). Among grade 1 findings, thin acetowhite epithelium was the most frequent (80.51%). Grade 2 findings and vascular patterns were rare. The positive predictive values of the micropapillary pattern were 55.98% for low-grade VaIN and 5.98% for high-grade VaIN. The specificity of iodine negativity was 10.92% for low-grade VaIN and 8.30% for high-grade VaIN. There were significant differences in the maximum size of single lesions and in the number of lesions among different grade lesion groups. Conclusion The agreement between colposcopy findings utilizing the 2011 IFCPC terminology and vaginal pathology is moderate, and more definite findings for high-grade VaIN may be needed. The micropapillary pattern can be considered an alternative low-grade finding, while iodine staining is nonspecific for all lesions. Scattered and spotty lesions suggest low-grade VaIN, while large single lesions suggest high-grade VaIN.

Abstract
Vaginal intraepithelial neoplasia (VAIN) is a rare disease associated with human papillomavirus infection. High-grade VAIN is typically treated with either excisional or ablative therapy. However, recurrent VAIN lesions are common and these treatments cause vaginal scarring. Recent studies have indicated that 5% imiquimod is an effective treatment for VAIN. The present report describes a case of a woman diagnosed with recurrent VAIN 3 who was treated with a 5% topical imiquimod cream and achieved a complete response after excision and CO2 laser vaporization. A 53-year-old, gravida 5, para 2 postmenopausal woman who was diagnosed with papillary squamous cell carcinoma by biopsy underwent conization, total abdominal hysterectomy and bilateral salpingo-oophorectomy. A histological examination revealed grade 3 cervical intraepithelial neoplasia with free surgical margins. At 3 years after the hysterectomy, the vaginal smear revealed atypical squamous cells, leading to a pathological diagnosis of VAIN 3. Partial vaginectomy was performed, and VAIN 3 was detected in the lesion with positive margins. At 4 months into follow-up, the vaginal smear revealed a high-grade squamous intraepithelial lesion (HSIL), and subsequent biopsy during colposcopy revealed a pathological diagnosis of VAIN 3. At 3 months after CO2 laser vaporization, the vaginal smear revealed HSIL with suspected recurrence and imiquimod treatment was initiated. One sachet of 5% imiquimod cream (0.25 g) was placed in the entire vagina three times per week for 14 weeks with no apparent complications. At 3 years after the treatment, there has been no recurrence. This case demonstrated that topical imiquimod with careful follow-up is an effective treatment for VAIN and is well-tolerated. Further clinical evidence of the effectiveness and safety of imiquimod in patients diagnosed with VAIN is required.

Abstract
BACKGROUND The limited sensitivity of Papanicolaou (Pap) cytology and the low specificity of HPV testing in detecting cervical or vaginal lesions means that either precancers are missed or women without lesions are overtreated. To improve performance outcomes, p16/Ki-67 dual-stain cytology has been introduced as a useful biomarker. METHODS A prospective, cross-sectional study was performed and included 599 patients. Clinical performance estimates of Pap cytology, HPV DNA assay, and p16/Ki-67 dual-stain cytology for the detection of CIN2+/VAIN2+ were determined and compared. RESULTS The sensitivity and specificity of p16/Ki-67 dual-stain cytology in detecting histology proven CIN2+/VAIN2+ was 91.6% and 95.0%, respectively, while that of Pap cytology was 42.1% and 95.2%, respectively, and that of HPV DNA testing was 100% and 41.6%, respectively. Among the three tests, the AUC of p16/Ki-67 immunocytochemistry was the largest, both for detecting cervical lesions and vaginal lesions, at 0.932 and 0.966, respectively. Among women who were HPV 16/18 positive or 12-other hrHPV positive and Pap positive (≥ASCUS), dual staining reduced the number of unnecessary colposcopy referrals from 274 to 181. Among the women who were 12-other hrHPV positive and Pap negative, dual staining could prevent underdiagnosis in six patients with CIN2+/VAIN2+ when used as a triage marker. Dual staining also identified four women with high-grade lesions detected by diagnostic conization but with negative colposcopy-guided biopsy results. CONCLUSION p16/Ki-67 dual staining may be a promising tool for predicting high-grade cervical and vaginal lesions.

Abstract
Vaginal intraepithelial neoplasia (VAIN) is often found by chance. We investigated the prevalence of VAIN and related human papillomavirus (HPV) types in comparison with cervical intraepithelial neoplasia (CIN). This study enrolled 648 women who were referred to the outpatient clinic of Kanazawa Medical University Hospital for abnormal cytology from January 2009 to January 2019. HPV genotypes were determined using Genosearch-31 + 4, which can detect 35 different HPV types. Colposcopy was performed at the first visit by an experienced gynecological oncologist. Among 611 subjects with squamous cell lesions, 107 (17.5%) VAIN cases were identified, and 67 (11.0%) women had both VAIN and CIN. Ultimately, 72 VAIN1, 15 VAIN2/3, 203 CIN1, 249 CIN2/3, 32 cervical squamous cell carcinomas (SCC), and one vaginal SCC (Vag-SCC) were identified. The prevalences of VAIN1, VAIN2/3, and Vag-SCC were 35.5%, 6.0%, and 3.1% of equivalent cervical lesions, respectively. The VAIN patients were older than the CIN patients (P = .002). About half of the VAIN cases were diagnosed during the follow-up. Multiple HPV infections were found in 42.9% of the VAIN and CIN patients. HPV52, 16, 51, 53, and 56 were the most common types in VAIN, whereas HPV16, 52, 58, 51, and 31 predominated in CIN. HPV18 was rare in VAIN, HPV58 was more common in CIN than in VAIN, and HPV53 and HPV73 were more common in VAIN. In conclusion, VAIN1 was identified more frequently than we expected. Various HPV types were identified in the vagina, which is likely a reservoir for HPV.

Abstract
Purpose Due to the rarity of vaginal intraepithelial neoplasia (VAIN), it is impossible to define the best treatment approach or to assess vaginal morbidity. However, brachytherapy (BT) could be a valuable choice for VAIN grade 3 (VAIN3). The aim of this paper was to report a single-institution study of the application of high-dose-rate BT and to evaluate clinical outcomes as well as to investigate the dose-effect relationship for vaginal stenosis. Material and methods We retrospectively collected hospital records and treatment plans of 14 consecutive women treated in our department from August 2010 to August 2016, with HDR-BT delivered using iridium-192 by a remote after-loading system. Doses in 3D-planned treatment based on computed tomography (CT) were prescribed in high-risk clinical target volume (HR-CTV) at the vaginal wall. Vaginal stenosis was defined as vaginal shortening/narrowing according to CTCAE4.1. The International Commission on Radiation Units & Measurements (ICRU) bladder and rectal points were used for dose report analysis. The posterior-inferior border of the symphysis points was used to derive reference points. The median age of the enrolled women was 60 years, and the median total radiation dose delivered was 35 Gy. Results During a median period of 15 days, the treatment was well tolerated, and no interruption was necessary. Acute toxicity was minimal, whereas late toxicity appeared in 4 patients as G2 and in 3 patients as G3 vaginal stenosis. Patients with stenosis G ≥ 2 received a higher median dose to the rectal point and were mainly over 60 years old. Conclusions Patients with VAIN3 seemed to benefit from BT. It is generally assumed that the vagina is radio-resistant, and no constraints have yet been set, but sexual dysfunction after BT is an important cause of long-term distress. Finding applicable dose limits to the vagina could improve patients’ quality of life.

Abstract
We estimated the overall and type-specific prevalence of human papillomavirus (HPV) and p16 overexpression in vaginal cancer and vaginal intraepithelial neoplasia (VaIN). We conducted a systematic search of PubMed, Embase and Cochrane Library to identify studies published between 1986 and 2017 using PCR-based or Hybrid Capture 2 tests to evaluate the presence of HPV DNA and/or using any method to detect p16 overexpression in VaIN, vaginal squamous cell carcinoma (VaSCC), or other types of vaginal cancer. Applying a random effects model, we estimated the pooled prevalence of HPV and p16 overexpression along with 95% confidence intervals (CIs). The I2 statistic was used to assess heterogeneity. We included 26 studies, reporting HPV prevalence and six studies evaluating p16 overexpression. The pooled HPV prevalences in VaSCC (n = 593) and VaIN (n = 1,374) were 66.7% (95% CI = 54.7-77.8) and 85.2% (95% CI = 78.2-91.0), respectively. Substantial inter-study heterogeneity was observed, and analyses stratified on geographic region, type of tissue, HPV detection method or PCR primer type did not fully explain the observed heterogeneity. The most predominant HPV type among the HPV positive VaSCC and VaIN cases was HPV16, followed by HPV33, and HPV45 (in VaIN) and HPV18, and HPV33 (in VaSCC). In pooled analyses, 89.9% (95% CI = 81.7-94.6) of HPV positive and 38.9% (95% CI = 0.9-90.0) of HPV negative vaginal cancers were positive for p16 overexpression. Our findings suggest that vaccination against HPV might prevent a substantial proportion of vaginal neoplasia and highlight the need for further studies of the possible clinical value of p16 testing in these patients.

Abstract
The purpose of this prospective cohort study is to evaluate the importance of screening and its diagnostic accuracy compared with the pathological diagnosis of cervical intraepithelial neoplasia (CIN) with vaginal intraepithelial neoplasia (VAIN).The prospective study enrolled 419 patients (pts) and was conducted between February 1, 2015 and January 31, 2016 at Beijing Obstetrics and Gynecology Hospital, Capital Medical University.All enrolled pts underwent multipoint biopsy of cervix and vaginal wall directed by colposcopy. All samples of biopsy underwent pathological examination. Among them, 201 pts (48.0%) were diagnosed with CIN, 218 pts (52.0%) were diagnosed with cervicitis, and 51 pts (12.2%) were diagnosed with VAIN. It was found that the incidence of CIN in pts was 4 times higher than that of VAIN. In all 419 patients enrolled, 218 pts had cervicitis with 13 pts (6.0%) of VAIN. There were 201 pts of CIN with 38 pts (18.9%) of VAIN: including 53 pts of CIN3 with 12 pts (22.6%) of VAIN; 49 pts of CIN2 with 9 pts of VAIN (18.4%), and 99 pts of CIN1 with 17 pts of VAIN (17.2%). The incidence of CIN with VAIN (18.9%) was significantly higher than cervicitis with VAIN (6.0%) (χ = 16.39, P = .00). Our results showed that there was a significant consistency between cervical lesions and vaginal lesions (χ = 135.91, P = .00), which indicated that the increase of CIN grades may be related to an increase of the VAIN grades. Our results also showed the significant (p < .05) increase of CIN and VAIN with age (<40 years Kappa = 0.04; 40-50 years Kappa = 0.11; >50 years Kappa = 0.28).This study showed that cytological test can be used as a routine screening method for cervical lesions and vaginal diseases. If the cytology result shows abnormality, and pathological examination confirms that there is no obvious abnormal cervical disease, colposcopy directed vaginal multipoint biopsy should be conducted to exclude vaginal disease. All patients of CIN should routinely undergo vaginal multipoint biopsy (1/3 upper vagina), especially in patients with high-grade CIN and age older than 50 years.

Abstract
BACKGROUND AND OBJECTIVE We aimed to evaluate responses to photodynamic therapy (PDT) and its long-term efficacy in preserving normal anatomy and function in women with premalignant lesions of the lower genital tract. STUDY DESIGN/MATERIALS AND METHODS Fifteen patients received PDT for vulvar intraepithelial neoplasia (VIN), vaginal intraepithelial neoplasia (VAIN), or vulvar Paget's disease between January 2003 and December 2013. Patients underwent colposcopy and/or vulvoscopy for assessment of lesions. Surface photoillumination with a 630-nm red laser light was applied to the lesions 48 hours after intravenous injection of 2 mg/kg photosensitizer (PSZ; Photogem®). The light dose to the lesions was 150 J/cm2 . RESULTS The median age of the 15 patients (VIN II: 3, VIN III: 4, VAIN II: 2, VAIN III: 3, Paget's disease: 3) was 42.3 years. The complete response (CR) rate was 80% (12/15) at the 3-month follow-up and 71.4% (10/14) at the 1-year follow-up. There were two cases of persistent disease at the 3-month follow-up. One patient with persistent disease underwent partial vulvectomy three times for repetitive recurrence, and the other received secondary PDT with topical 5-aminolevulinic acid (5-ALA) and subsequently showed no evidence of disease (NED). Another patient achieved 90% remission through a combination of additional alternative treatments after showing partial response (PR). In two cases of CR, recurrence was observed at the 1-year follow-up. Regarding adverse events, photosensitivity reactions such as facial edema and urticaria occurred in 13.3% (2/15) and perineal pain occurred in one patient. CONCLUSIONS PDT may be an effective alternative treatment for premalignant lesions of the female lower genital tract to preserve normal anatomy and sexual function without therapeutic impairment.

Abstract
Poly-gamma-glutamic acid (γ-PGA) is a natural polymer that is synthesized by Bacillus species and has been reported to have antitumor activity. The aim of this study was to investigate the effect of γ-PGA on the treatment of vaginal intraepithelial neoplasia (VAIN). A retrospective observational study on γ-PGA therapy for biopsy-proven VAIN was conducted. The efficacy was assessed by evaluating the results of Pap cytology and the viral load of high-risk HPV at three time points: at enrollment, and at the first and second post-treatment visits. Of 17 patients treated with γ-PGA, only 12 patients who had a high-risk HPV infection were included in the analysis. Histology was VAIN1 in seven patients, VAIN2 in two patients, and VAIN3 in three patients. γ-PGA was administered for newly diagnosed VAIN in five (41.7%) patients and persistent VAIN in seven (58.3%) patients for the mean time of 4.5 months. At the first and second post-treatment visits, cytological regression was observed in five (41.7%) and six (50%) patients, respectively. Regarding the HPV load, the overall response rate was 66.7%, and the mean level was 670.6 ± 292.5 RLU at the first follow-up, which was lower than the initial viral load of 1,494.8 ± 434.5 RLU (p = 0.084). At the second follow-up, the overall response rate was 58.3%, and the mean viral load level was 924.2 ± 493.7 RLU. γ-PGA may be helpful for the cytological regression and reduction of viral load in patients with high-risk HPV-positive VAIN, suggesting that γ-PGA is a promising treatment option for primary or persistent VAIN.

Abstract
OBJECTIVE To assess the clinical response to imiquimod 5% cream in patients with persistent human papillomavirus (HPV) infection after treatment of genital intraepithelial neoplasia. MATERIALS AND METHODS Imiquimod 5% cream was applied to treat 76 women with persistent HPV after surgical therapy for cervical or vaginal intraepithelial neoplasia (CIN or VAIN). One sachet of cream was placed in the cervical os and vagina with an applicator twice weekly for 8 weeks. Repeated HPV evaluation and Papanicolaou (Pap) smear and/or biopsy were performed 3 months following treatment completion. RESULTS In total, 58 of the 76 patients (76.3%) were clear of HPV infection and had normal Pap smears after administration of imiquimod cream. Although atypia or mild dysplasia was noted in 15 of the 18 patients (83.3%) with persistent HPV infection after imiquimod cream treatment, the degree of severity was noticeably less than the initial diagnosis in most of these patients. Persistent HPV positivity was observed in 12 of the 64 patients (18.8%) with CIN and 6 of the 12 patients (50.0%) with VAIN. CONCLUSION Topical imiquimod 5% cream may be beneficial in most cases of genital intraepithelial neoplasia, especially CIN, with persistent HPV following surgical treatment.
