Clinical characteristics, HPV involvement, and demographic risk factors in women with cervical intraepithelial neoplasia complicated by vaginal intraepithelial neoplasia.

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.

Vaginal malignant peripheral nerve sheath tumor treated with complete surgical resection and postoperative radiation therapy.

Malignant peripheral nerve sheath tumors (MPNSTs) are neoplasms originating from or differentiating into nerve sheaths of peripheral nerves. Vaginal origin is rare, with only six vaginal primary cases reported to date. A 55-year-old woman presented to our hospital with a 7 cm vulvar mass. Tumor biopsy results were suspicious of sarcoma, and pelvic magnetic resonance imaging and hysterofiberscopy showed that the tumor originated from the lower vagina. The mass was transvaginally excised, and histological examination confirmed the diagnosis of a vaginal MPNST with negative surgical margins. The patient underwent radiotherapy because the risk of recurrence was high, owing to the large tumor size and high mitotic index. The patient remained recurrence-free for 1 year after the primary treatment. This is the first case of a high-risk vaginal MPNST that avoided early disease recurrence with additional radiotherapy after complete tumor resection.

Clinical Characteristics and Detection Sensitivity of Cervical Cancer Screening in Vaginal Intraepithelial Neoplasia.

OBJECTIVE: This study aimed to investigate the characteristics and screening history of vaginal intraepithelial neoplasia (VaIN) or vaginal cancer and compare the sensitivity of cytology and human papillomavirus (HPV) tests on the cervix against vaginal and cervical high-grade squamous intraepithelial lesion or cancer. METHODS: This study included patients who underwent colposcopy-directed biopsy and were diagnosed with VaIN or vaginal cancer from February 2013 to November 2022. Clinical information was obtained from the medical records of the department. Statistical analysis was performed on SPSS 26.0 (IBM Corp, Armonk, NY) using t test, chi-square, and Fisher exact tests. RESULTS: A total of 1,166 patients were included in this study. The median age of VaIN2+ patients was 50.5 years, whereas VaIN1 reported a median age of 42.1 years old, p < .001. This study reported that VaIN was significantly and positively correlated with cervical lesions (r = 0.244). The high-risk HPV (hr-HPV) detection rate was 88.2% (858/973) in VaIN and 95.2% in VaIN2+. Human papillomavirus 16 was the most prevalent HPV type in VaIN2+, which accounted for 54.9%, followed by HPV58 (19.5%), HPV52 (15.2%), HPV51 (12.2%), and HPV18 (11.0%). The sensitivity of hr-HPV and cytology tests on the cervix for detecting VaIN2+ was 94.7% and 83.4%, respectively. Both tests were not significantly different from detecting cervical intraepithelial neoplasia 2+. CONCLUSIONS: Human papillomavirus 16 is the dominant HPV type in vaginal precancer lesions. Cervical cancer screening has similar sensitivity for VaIN2+ as for cervical intraepithelial neoplasia 2+, with hr-HPV testing showing higher sensitivity than cytology.

Mullerian Polyp of the Vagina: Report of Three Cases of a Previously Undescribed Lesion With Discussion of the Differential Diagnosis.

Benign and malignant neoplasms of the vagina are rare. We report 3 primary vaginal polypoid lesions involving the upper or mid-vagina in patients aged 40, 60, and 67 years. The lesions bore a striking morphologic resemblance to benign endocervical or endometrial polyps and we suggest the designation Mullerian polyp of the vagina. As far as we are aware, similar cases have not been reported previously in the literature. Follow-up ranging from 6 to 21 months has been uneventful. In reporting these cases, we discuss the possible origin and differential diagnosis and review vaginal lesions with a benign glandular component.

Characteristics of high-risk HPV infection in women with vaginal intraepithelial neoplasia in Beijing, China.

We evaluated the characteristics of high-risk human papillomavirus (Hr-HPV) infection in different grades of vaginal intraepithelial neoplasia (VaIN). 7469 participants were involved in this study, of which 601 were diagnosed with VaIN, including single vaginal intraepithelial neoplasia (s-VaIN, n = 369) and VaIN+CIN (n = 232), 3414 with single cervical intraepithelial neoplasia (s-CIN), 3446 with cervicitis or vaginitis and 8 with vaginal cancer. We got those results. First, the most popular HPV genotypes in VaIN were HPV16, 52, 58, 51, and 56. Second, our study showed that higher parity and older age were risk factors for VaIN3 (p < 0.005). Third, the median Hr-HPV load of VaIN+CIN (725) was higher than that of s-CIN (258) (p = 0.027), and the median Hr-HPV load increased with the grade of VaIN. In addition, the risk of VaIN3 was higher in women with single HPV16 infections (p = 0.01), but those with multiple HPV16 infections faced a higher risk of s-VaIN (p = 0.003) or VaIN+CIN (p = 0.01). Our results suggested that women with higher gravidity and parity, higher Hr-HPV load, multiple HPV16 infections, and perimenopause or menopause status faced a higher risk for VaIN, while those with higher parity, single HPV16 infections, and menopause status are more prone to VaIN3.

A single-institutional retrospective analysis of factors related to vaginal intraepithelial neoplasia.

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.

[Vaginal leiomyosarcoma in pregnancy]. / Leiomiosarkoma vlagalishcha u beremennoi.

The article presents a rare clinical observation of a vaginal tumor detected during pregnancy, which prevented delivery through the natural birth canal and caused a cesarean section at full term. According to the primary biopsy at 34 weeks, neurofibroma was diagnosed. In the postpartum period, due to profuse bloody discharge, the patient was admitted to the Moscow Regional Research Institute of Obstetrics and Gynecology for surgical treatment, where, according to the results of a morphological study of the removed tumor, vaginal leiomyosarcoma was diagnosed.

Clinical analysis of 175 cases of vaginal intraepithelial neoplasia.

OBJECTIVE: To evaluate the risk factors related to vaginal intraepithelial neoplasia (VaIN) severity. STUDY DESIGN: This retrospective study included patients with histologically confirmed VaIN diagnosed at Hubei Provincial Maternal and Child Health Hospital, China, between January 2017 and October 2021. The primary outcomes were persistence, remission, progression, and recurrence. Multiple ordinal logistic regression analysis was used to analyze the risk factors of VaIN severity. RESULTS: A total of 175 patients were included, 135 (77.1%) with VaIN 1, 19 (10.9%) with VaIN 2, and 21 (12%) with VaIN 3. Patients with VaIN 3 were older than those with VaIN1 2 (P < 0.001). The ratio of patients with concomitant cervical lesions increased with VaIN grade (23.7%, 47.4%, and 47.6% for VaIN 1, 2, and 3, respectively). The proportion of patients with intraepithelial neoplasia (CIN) 3 increased with the VaIN grade (3.1%, 44.5%, and 80% for VaIN 1, 2, and 3, respectively, respectively; all P < 0.001). In patients with VaIN 1, 19.4% had regression (spontaneous regression in 90.5%) and 80.6% underwent laser ablation (regression in 93.1%). In patients with VaIN 2 and 3, 3.1% showed no regression, 53.1% underwent laser ablation (regression in 76.4%), and 73.8% underwent excision (regression in 78.7%). Age (OR = 1.05, 95 %CI: 1.01-1.10, P = 0.010) and concomitant cervical lesion (OR = 6.99, 95 %CI: 2.31-21.12, P = 0.001) were independent risk factors for the severity of VaIN. CONCLUSION: Age and cervical lesions might be the risk factors for VaIN severity.

Late cervical and vaginal clear cell adenocarcinoma in women exposed in utero to diethylstilbestrol: Evaluation and screening.

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.

Primary clear cell adenocarcinoma of the rectovaginal septum: A rare case report.

RATIONALE: Primary clear cell adenocarcinoma of the rectovaginal septum is a very rare event. PATIENT CONCERNS: We reported a case of a 55-year-old woman diagnosed with a lump in the vaginal rectal septum after undergoing hysterectomy with bilateral salpingo-oophorectomy in 2017, who was admitted to our department due to vaginal bleeding. Magnetic resonance imaging of the pelvis indicated the vaginal rectal space cystic and solid mass about 110 mm × 100 mm × 140 mm in size. DIAGNOSIS: The pathological diagnosis of postoperative was clear cell adenocarcinoma. INTERVENTIONS: Abdominal laparotomy showed a solid block of the vaginal rectal septum. Surgery was performed to reduce the tumor. OUTCOMES: This patient received 8 courses of combined chemotherapy courses after surgery for the residual lesion and achieved a complete response. LESSONS: Due to the rare observation of the growth pattern, the cell morphology and immune phenotype are not specific, and clinical and pathological diagnosis is difficult. Introducing the diagnosis and treatment of this case and reviewing the literature provide a relevant reference for clinicians identification and diagnosis and treatment of this rare case.

Primary HPV-Associated Enteric-Type Adenocarcinoma of Vagina: A Case Report.

Primary enteric type adenocarcinomas of the vagina are extremely rare. We present a 63-year-old woman who had a polypoid mass localized to the distal vagina. The lesion was composed of a columnar glandular cell proliferation with focal cribriforming, reminiscent of tubular adenoma. Immunohistochemical stains were notable for expression of enteric markers (CDX2 and KRT20), as well as negativity for Mullerian markers (PAX8, ER, and PR), diffuse expression for p16, and positivity for high-risk HPV mRNA expression. Ultimately, a diagnosis of vaginal primary HPV-associated enteric type adenocarcinoma was rendered for this unusual lesion. To our knowledge, no prior cases of HPV-associated enteric type adenocarcinomas of the vagina have been described before.

Postmenopausal Vaginal and Cervical Cancer Risk Related to In Utero Diethylstilbestrol Exposure.

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.

High-grade vaginal intraepithelial neoplasia and recurrence risk: analysis of an Italian regional referral center series.

PURPOSE: The main aim of this study was to investigate the long-term risk of disease recurrence in women treated for high-grade vaginal intraepithelial neoplasia (HG-VaIN). METHODS: We conducted a retrospective analysis on a cohort of 82 women diagnosed with HG-VaIN between 2010 and 2021 at the "Regional Referral Center for Prevention, Diagnosis and Treatment of HPV-related Genital Disorders", Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico, Milan, Italy. All women underwent either ablative treatment (CO2 laser ablation or electrocoagulation) or cold-knife excision. RESULTS: In our series, the recurrence rate following treatment was 17%. The 5-year cumulative probability of recurrence was 30.4% and the median time to recurrence was 15.5 months. None of the patients progressed to invasive vaginal cancer during follow-up. A concomitant cervical or vulvar intraepithelial lesion was significatively associated with an increased risk of recurrence (p = 0.006). CONCLUSIONS: The results of our study suggest that women with HG-VaIN are at high risk of developing disease recurrence after treatment, especially patients with a concomitant cervical or vulvar intraepithelial lesion. In these women strict monitoring is mandatory to obtain an early identification of recurrence.

Prolapsing vaginal fibroepithelial polyp.

Although uncommon, vaginal fibroepithelial polyps can present as prolapsing vaginal tissue, causing discomfort and anxiety. Surgical excision of the polyps can provide a minimally invasive solution. In this case, we describe a nulliparous female in late adolescence who presented for evaluation of tissue protruding through the vagina. On exam, a 5×4 cm fibroepithelial polyp was extending from the distal posterior vagina on a broad stalk. Successful transperineal surgical excision was performed. Fibroepithelial polyps, although uncommon, can be a cause for prolapsing vaginal tissue and should be part of the differential diagnosis, especially in patients who have no risk factors for pelvic organ prolapse. They can be excised vaginally, alleviating symptoms and distress. Because they sometimes recur, continued surveillance with gynaecological exams is recommended.

Small cell neuroendocrine carcinoma of vagina: Report of a unique case with literature review.

Small cell carcinoma (SCC) of vagina is extremely rare. The association between this tumor and high-risk HPV infection is unclear. To our knowledge, HPV status has been reported in only 3 previous cases of SCC of vagina. Herein, we present a unique case of vaginal small cell carcinoma with discordant HPV testing results between vaginal and cervical samples. We also review and discuss findings from previously reported cases of small cell carcinoma of vagina.

Primary vaginal endodermal sinus tumor in infants and children: experience from a tertiary center.

BACKGROUND: The objective of the study was to analyze the clinical features, treatment, and outcomes of primary vaginal endodermal sinus tumor (EST) in infants and children treated in a tertiary center. METHODS: Clinical data of patients with pathologically confirmed primary vaginal EST in our hospital from January 1997 to December 2017 were retrospectively reviewed and analyzed. RESULTS: A total of 21 patients were included in this study. The median age at diagnosis was 11 months (range, 4-44 months). The most common manifestations were abnormal vaginal bleeding, and a polypoid mass protruding from the vagina. Chemotherapy based on PEB (cisplatin, etoposide, bleomycin) regimen was given, and serum alpha-fetoprotein (AFP) levels dropped to normal levels after 2 to 4 cycles of chemotherapy (median, 2 cycles). After 3 to 13 cycles of chemotherapy, with a median of 5 cycles, 20 patients achieved complete remission (95.2%). The median follow-up time was 80 months (range, 4-281months). At the time of the last follow-up, 19 cases were alive without disease, and the survival rate was 90.5%. CONCLUSION: Vaginal EST is a very rare malignant germ cell tumor and is sensitive to chemotherapy. Conservative surgery combined with PEB chemotherapy is an effective way of treatment. Serum AFP and imaging examinations can monitor the treatment response and recurrence.

Risk of clear-cell adenocarcinoma of the vagina and cervix among US women with potential exposure to diethylstilbestrol in utero.

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.

Efficacy and safety of photodynamic therapy mediatied by 5-aminolevulinic acid for the treatment of vaginal high-grade intraepithelial lesions.

BACKGROUND: Vaginal high-grade squamous intraepithelial lesion (HSIL) (vaginal intraepithelial neoplasia [VAIN] grade 2-3) is clinically, a precancerous lesion condition with an estimated progression rate of 10%-20%. Therefore, treatment is recommended. Because traditional treatments have limited effects, high expense and complications, here we evaluated the efficacy and safety of topical 5-aminolevulinic acid (ALA)-based photodynamic therapy (PDT). METHODS: This study consisted of 56 female patients diagnosed with vaginal HSIL. A 20% 5-ALA jelly formation was topically applied to the vaginal wall, followed by 635 nm PDT at 7-14 days intervals. Cytology, human papillomavirus (HPV) genotyping, colposcopy, and pathology were assessed after treatment. RESULTS: Among the 56 patients in our study, 47 (83.9%) had VAIN 2 and 9 (16.1%) had VAIN 3. 35 patients underwent three courses of PDT treatment, 19 experienced six courses, and two experienced nine courses. The total pathological regression rate was 87.5%, and the HPV clearance rate during the 6-month follow-up was 41.9%. Lesions located in the vaginal stump after hysterectomy seem to be difficult to treat. 9%(4/44) and 23%(7/30) patients had recurrent disease during the 6-month and 1-year follow-up time point. The most common adverse event was increased vaginal discharge, other side effects include abdominal pain, vulvar pruritus, and vaginal bleeding. No severe adverse effect was observed during the treatment. CONCLUSION: Photodynamic therapy mediatied by 5-aminolevulinic acid is an effective and safe treatment for vaginal HSIL with minimal side effects.

Vaginal tumours in childhood: a descriptive analysis from a large paediatric medical centre.

PURPOSE: Malignant tumours of the vagina are very rare in children. The purpose of this study was to retrospectively analyse the clinical presentation, treatment, and outcome of vaginal tumours in children treated in a single institution. METHODS: This study retrospectively analysed the clinical data of children diagnosed with vaginal malignant tumours who were admitted to the Beijing Children's Hospital of Capital Medical University from January 2007 to December 2020 and followed these patients to observe their prognoses and outcomes. RESULTS: During 13 years, a total of 33 children were included in this study, including 13 children with rhabdomyosarcoma and 20 children with endodermal sinus tumours. The average age at diagnosis was 20.4 months. The main clinical manifestations were vaginal bleeding and protruding masses. Of the 13 children with vaginal rhabdomyosarcoma, 12 were treated with multidrug chemotherapy combined with conservative tumour resection, and their tumours completely resolved; only one child underwent vaginectomy and hysterectomy. Twenty children with vaginal endodermal sinus received PEB chemotherapy. Among these patients, the tumour disappeared after chemotherapy in 12 children, and the remaining nodular tumour foci in 8 children were confirmed to be necrotic tissue by pathology. CONCLUSION: Our research confirms that chemotherapy combined with conservative surgical treatment is effective for treating children with vaginal malignancies.
