[PMID: 38254851 PMCID: PMC10814353 DOI: 10.3390/cancers16020362] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2023] [Accepted: 01/09/2024] [Indexed: 01/24/2024] Open
Abstract
Radiotherapy (RT) has a fundamental role in the treatment of gynecologic malignancies, including cervical and uterine cancers. Hypofractionated RT has gained popularity in many cancer sites, boosted by technological advances in treatment delivery and image verification. Hypofractionated RT uptake was intensified during the COVID-19 pandemic and has the potential to improve universal access to radiotherapy worldwide, especially in low-resource settings. This review summarizes the rationale, the current challenges and investigation efforts, together with the recent developments associated with hypofractionated RT in gynecologic malignancies. A comprehensive search was undertaken using multiple databases and ongoing trial registries. In the definitive radiotherapy setting for cervical cancers, there are several ongoing clinical trials from Canada, Mexico, Iran, the Philippines and Thailand investigating the role of a moderate hypofractionated external beam RT regimen in the low-risk locally advanced population. Likewise, there are ongoing ultra and moderate hypofractionated RT trials in the uterine cancer setting. One Canadian prospective trial of stereotactic hypofractionated adjuvant RT for uterine cancer patients suggested a good tolerance to this treatment strategy in the acute setting, with a follow-up trial currently randomizing patients between conventional fractionation and the hypofractionated dose regimen delivered in the former trial. Although not yet ready for prime-time use, hypofractionated RT could be a potential solution to several challenges that limit access to and the utilization of radiotherapy for gynecologic cancer patients worldwide.

Survival rate of vaginal cancer in Asian countries: a systematic review and meta-analysis. Ann Med Surg (Lond) 2023; 85:5577-5583. [PMID: 37920653 PMCID: PMC10619580 DOI: 10.1097/ms9.0000000000001097] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Accepted: 07/13/2023] [Indexed: 11/04/2023] Open
Abstract
Introduction Vaginal cancer is one of the major causes of mortality in women, which mostly takes place in low- and middle-income countries. Assessing the survival rate of vaginal cancer is essential to investigate the success rate of current treatments and screening tools. This study aims to determine the survival rate of vaginal cancer in Asia. Methods This systematic review was carried out using four international databases, including Medline/Pubmed, ProQuest, Scopus, Web of Knowledge, and also Google Scholar. Articles were investigated up to the end of August 2021. The authors utilized the Newcastle-Ottawa Scale to evaluate the quality of the articles. Evaluating the papers for heterogeneity was performed using the Cochrane test and I² statistic. Meta-regression analysis was also applied based on the year of the study. Results Three articles (13 records) fulfilled the inclusion criteria. Based on the random model, the overall 5-year survival rate was 74.63%. Also, the rates of survival in relation to the type of treatment including chemotherapy, radiotherapy, or other modalities, were 78.53, 78.44, and 68.54%, respectively. According to meta-regression analysis, no correlation was found between the survival rate and the year of the study. Conclusion The vaginal cancer survival rate is lower in Asian countries compared to that of developed countries. Increasing patient survival rates in such countries is crucial by implementing newer diagnostic tools, advanced surgical techniques, and goal-oriented treatments. Early diagnosis in lower stages and educating the populations about risk factors and preventative measures are also necessary for raising the rate of survival.

Abstract
The Centers for Disease Control and Prevention sponsored a project conducted by the American College of Obstetricians and Gynecologists to develop educational materials for clinicians on the prevention and early diagnosis of gynecologic cancers. For this final module, focusing on the cancers of the lower anogenital tract (vulva, vagina, and anus), a panel of experts in evidence assessment from the Society for Academic Specialists in General Obstetrics and Gynecology, ASCCP, and the Society of Gynecologic Oncology reviewed relevant literature and current guidelines. Panel members conducted structured literature reviews, which were then reviewed by other panel members. Representatives from stakeholder professional and patient advocacy organizations met virtually in September 2022 to review and provide comment. This article is the executive summary of the review. It covers prevention, early diagnosis, and special considerations of lower anogenital tract cancer. Knowledge gaps are summarized to provide guidance for future research.

Trends in incidence of invasive vaginal cancer in France from 1990 to 2018 and survival of recently diagnosed women - A population-based study. Eur J Obstet Gynecol Reprod Biol 2023; 283:125-129. [PMID: 36842246 DOI: 10.1016/j.ejogrb.2023.02.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 01/26/2023] [Accepted: 02/10/2023] [Indexed: 02/15/2023]
Abstract
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.

Abstract
Ovarian, uterine, and vulvovaginal cancers affect approximately 96,000 women per year in the United States, resulting in approximately 29,000 deaths annually. Routine screening protocols do not detect these malignancies; thus, the recognition of risk factors and evaluation of worrisome symptoms are essential for early detection and improved prognoses. Treatment is managed by gynecologic oncologists, and often involves a combination of surgery, chemotherapy, and possible radiation treatments. Survivor care is managed by the primary-care clinician: expert attention to the mental, physical, and sexual health of each patient will ensure the best outcomes and quality of life.

Abstract
Vaginal and vulvar malignancies are rare gynecologic malignancies but can be associated with high morbidity and mortality if undiagnosed and untreated. Advanced imaging modalities such as MRI enable assessment of the local extent of disease and evaluation for regional or distant spread. Accurate identification and description of the primary lesion and sites of involvement as well as detection and localization of suspicious lymph nodes are critical in guiding appropriate management. Additionally, radiologists should be aware of potential mimickers on imaging and the differential diagnoses for vaginal and vulvar lesions.

Abstract
BACKGROUND Vaginal neoplasms are rare. To study the survival of patients depending on tumour characteristics and age, the data from the national cancer registries in Germany were analysed. METHODS In a retrospective analysis, data from 2006 to 2015 on disease stage, survival, and factors that might affect prognosis were analysed. RESULTS Altogether, out of 4004 datasets, 2194 were deemed adequate to be included in the analysis. Overall survival at 5 years (5YSR) and relative survival (5RSR) were 48.6% (95%CI 45.4-52.1%) and 58.7% (95%CI 55.3-61.2%) for carcinomas, but significantly worse at 20.2% (95%CI 8.3-32.0%) and 24.2% (95%CI 16.4-32.0%) for melanomas and 38.3% (95%CI 23.3-53.5%) and 44.4% (95%CI 31.5-56.8%) for sarcomas. 5YSR and 5RSR correlated significantly with FIGO stages (5YSR: 66.9-10.1%; 5RSR: 81.7-11.9%, p = 0.04). Furthermore, survival depended on the absence of LN metastases (5RSR: 59.1% vs. 38.0%, p < 0.001), and the tumour grading had an influence (5RSR: 83.7-52.1%). We also noted that prognosis was worse for older patients ≥75 years (5RSR:51.2%) than for patients <55 years (62.2%) and 55-74 years of age (61.6%). CONCLUSION Unless LN metastases, local advanced tumours and G3 grading are associated with a worse prognosis. Relative survival of older patients decreases, perhaps indicating that treatment compromises have been made.

Abstract
OBJECTIVES To determine the prevalence of cellular debris (CD) on benign cervicovaginal liquid-based cytology (LBC) smears and which factors predict the presence and larger amount of CD. METHODS Cervicovaginal smears evaluated as negative for intraepithelial lesion or malignancy (NILM) between January 1st and March 31st, 2020, were retrospectively reviewed to record the presence and amount of CD. All smears were prepared with the SurePath platform. Patients' age and past medical and surgical histories were also retrieved. Multivariate regression analyses were performed to find positive predictors of a larger amount of CD. RESULTS 349 NILM smears were included in this study. The cohort consisted of 222 cervical smears (CS) and 127 vaginal smears (VS), which were taken from patients who had undergone hysterectomy. Overall, CD was observed in 111 (31.8%) cases. The positive predictors of CD were increasing age, specimen type (VS compared to CS), history of chemotherapy or radiation therapy (CRT), and more than mild background inflmmation. Among VS group, CD was present in 64 cases (50.4%) regardless of the time between the specimen collection and hysterectomy. Positive predictors in the VS group were age and more than mild inflammation. Contrary, in the CS group, the prevalence of CD was 21.2%, and age was the only positive predictor. Histories of CRT, conization and inflammation were not statistically significant positive predictors for CD among CS. CONCLUSIONS CD can be seen in as much as 50% of NILM smears taken after hysterectomy, regardless of the time since hysterectomy. Increasing age is a positive predictor of the presence and a larger quantity of CD. These findings are helpful when evaluating smears with moderate to abundant debris in the background with questionable cellular atypia.

Abstract
Squamous cell carcinoma (SCC) and adenocarcinoma (AC) are two main histological subtypes of solid cancer; however, SCCs are derived from different organs with similar morphologies, and it is challenging to distinguish the origin of metastatic SCCs. Here we report a deep proteomic analysis of 333 SCCs of 17 organs and 69 ACs of 7 organs. Proteomic comparison between SCCs and ACs identifies distinguishable pivotal pathways and molecules in those pathways play consistent adverse or opposite prognostic roles in ACs and SCCs. A comparison between common and rare SCCs highlights lipid metabolism may reinforce the malignancy of rare SCCs. Proteomic clusters reveal anatomical features, and kinase-transcription factor networks indicate differential SCC characteristics, while immune subtyping reveals diverse tumor microenvironments across and within diagnoses and identified potential druggable targets. Furthermore, tumor-specific proteins provide candidates with differentially diagnostic values. This proteomics architecture represents a public resource for researchers seeking a better understanding of SCCs and ACs. Squamous cell carcinomas are an aggressive cancer type which can occur in multiple organ systems. Here, the authors analyse the proteome of SCC cancers from 17 organs and show commonly dysregulated proteins independent of location.

Abstract
This study aimed to investigate the factors that affect survival in vaginal cancer by means of a large population-based database that had been monitored over a 42 year period (1975-2017). It was investigated which factors were most predictive in survival. This study evaluated the factors that affect survival in primary vaginal cancer as one of the rarest gynaecological cancers. Relationships were explored between survival and age and race of patient, in situ/invasive behaviour of tumour, histological type, stage, grade, surgical treatment, and year of diagnosis. Survival rate was found to be higher at younger ages and earlier stages, in in situ and squamous cell carcinomas, in the presence of previous surgery, and diagnosis from 2000 onward. It was shown that other causes were more predictive of mortality in older patients and that mortality due to other causes decreased in patients diagnosed from 2000 onward. Mortalities due to cancer were found to be lower in the patients who had underwent surgery.At the end of this study, an estimation model was developed for 10-year survival in vaginal cancer and software was created for the model. Impact StatementWhat is already known on this subject? Primary vaginal cancer is very rare, accounting for 2% of female genital tract malignancies. Due to its low incidence and difficulty of its final diagnosis, vaginal cancer has the least amount of data among all female genital tract malignancies. It is difficult for clinicians to estimate the survival with already limited data on vaginal cancer in the literature.What do the results of this study add? Survival rate was found to be higher at younger ages and earlier stages, in in situ and squamous cell carcinomas, in the presence of previous surgery, and diagnosis from 2000 onward. It was shown that other causes were more effective in mortality with older age and that mortality due to other causes decreased in patients diagnosed from 2000 onward. Mortalities due to cancer were found to be lower in the patients who had underwent surgery.What are the implications of these findings for clinical practice and/or further research? It is anticipated that such studies will contribute to the transformation of societal data collection methods into a prospective nature and lead the way for stronger survival estimation models to be developed in days to come.

Brachytherapy for the Conservative Treatment of Female Peri-Urethral Carcinoma. Cancers (Basel) 2022; 14:cancers14030845. [PMID: 35159114 PMCID: PMC8834286 DOI: 10.3390/cancers14030845] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2022] [Revised: 02/01/2022] [Accepted: 02/02/2022] [Indexed: 11/17/2022] Open
Abstract
Introduction: Peri-urethral cancers (PUC) are rare tumors. Brachytherapy (BT), either monotherapy or combined with radiation therapy, is a preferred treatment option to spare the morbidity of surgery and achieve organ preservation. We report, to the best of our knowledge, the largest experience of brachytherapy among women with PUC. Patients and Methods: This is a retrospective review of the medical records of female patients with PUC who underwent low- or pulse-dose-rate BT with or without external beam radiotherapy at Gustave Roussy between 1990 and 2018. Patients were categorized according to the treatment intention into a primary and recurrent group. The Kaplan-Meier method was used for survival analysis, and the Cox proportional-hazard model was used for univariate analysis. Brachythewharapy-related adverse events were reported according to Common Terminology Criteria for Adverse Events version 4. Results: We identified 44 patients with PUC who underwent BT. Of the 44 patients, 22 had primary tumors and 22 had recurrent tumors. Histologies were mainly adenocarcinoma (n = 20) and squamous cell carcinoma (n = 14). The median prescribed dose was 60 Gy for the 24 patients treated with BT alone and 20 Gy (IQ range: 15-56.25 Gy) for the 20 patients treated with BT in combination with EBRT. With a median follow-up of 21.5 months (range 7.5-60.8), a total of six patients experienced local relapse (17.5%). The 2-year overall survival probability was 63% (95%CI: 49.2-81.4%). The most common toxicities were acute genito-urinary grade 1-2 toxicities. At the last follow-up, four patients experienced focal necrosis. Conclusions: In this cohort of women with PUC undergoing BT, we observed an 80% probability of local control with acceptable morbidity. Though survival was poor, with high metastatic relapse probability, BT was useful to focally escalate the dose and optimize local control in the context of an organ sparing strategy.

Abstract
BACKGROUND Malignant transformation of endometriosis in extraovarian sites remains rare. Furthermore, the process is not definitely understood. CASE PRESENTATION Herein, we report the case of a 40-year-old premenopausal nulligravida woman who presented with vaginal bleeding and who was finally diagnosed with a vaginal cancer originating from endometriosis and with a synchronous endometrial cancer. A gynecologic examination revealed a multiple polypoid mass on the posterior vaginal fornix. Magnetic Resonance Imaging of the pelvis showed two masses abutting respectively on the anterior uterine wall, and in the rectovaginal septum. The patient underwent a total laparoscopic excision of the rectovaginal mass, radical hysterectomy and low anterior resection of the rectum. The lesions were diagnosed as endometriosis, endometriosis-associated complex hyperplasia and endometrioid cancer. Furthermore, a synchronous endometrioid endometrial cancer was reported. CONCLUSIONS This case revealed the multistep process of malignant transformation of deep infiltrating endometriosis. The progression was individualized between implantation sites and in the same organ.

Abstract
Primary vaginal carcinoma is rare. There are two pathogenetic pathways, one associated with HPV high-risk infection and another one with inactivation of p53. Vaginal Paget's disease is rare and mostly associated with vulvar disease or represents intravaginal spread of associated locoregional cancer. Diagnostic vaginal biopsies should be examined by step sections on H&E. Sentinel lymph nodes should be processed completely using ultrastaging. Morphology-based prognostic factors with good clinical evidence are tumour stage and lymph node status. Molecular markers are not currently relevant for treatment decision and prognosis.

Abstract
Surgery, including minimally invasive surgery, and radiotherapy are key modalities in the treatment of gynecological malignancies. The aim of this review is to offer the multidisciplinary care team a comprehensive summary of the intersections of surgery and radiotherapy in the local treatment of gynecological malignancies. Recent advances in radiotherapy are highlighted. Relevant publications were identified through a review of the published literature. Ovarian, endometrial, cervical, vaginal, and vulvar cancer were included in the search. Current guidelines are summarized. The role of radiotherapy in adjuvant as well as definitive treatment of these entities is synthesized and put into context with surgery, focusing on survival and quality of life. Although these outcomes have improved recently, further research must be focused on the number of life years lost, and the potential morbidity encountered by patients.

Abstract
Background Primary vaginal cancer (PVC) is a rare gynecological malignant tumor and we know little about its survival and prognostic factors. The purpose of this study is to evaluate the potential survival and prognostic factors in women with PVC. Methods We used data from the Surveillance, Epidemiology, and End Results (SEER) program to identify 1,781 women who had been diagnosed with PVC between 2004 and 2014. Univariate and multivariable analyses were used to evaluate cases survival and prognostic factors. A stratified analysis was further performed to analyze the prognostic factors in each stage. Results There were 20.0% of patients aged ≥80 years and most women were married, 42.1%, and then widowed, 25.2%. The histology types include squamous (74.5%), adenocarcinoma (16.7%), melanoma (3.3%) and sarcoma (1.5%). Five-year cause-specific survival (CSS) rates were overall: 57.8%, Stage I: 76.4%, Stage II: 61.9%, Stage III: 53.3% and Stage IV: 22.5%. Univariate analysis showed that age, marital status, race, pathological grading, histology, TNM stage, tumor size, surgery and radiation were related to prognosis. The 5-year CSS of married women is 64.4%, while those of divorced/separated and widowed are 56.6% and 44.1%, respectively. Multivariate analysis indicated that age, histology, TNM stage, tumor size, surgery and radiation were independent prognostic factors. The elderly (≥80) cases and those with melanoma were correlated to worse prognosis at any stage of PVC. As tumor stage progressed, both of the ≥80 years old patients and the melanoma cases showed a decline tendency of mortality risk. Conclusions PVC is a rare gynecological malignant tumor and more likely to occur among older women. Squamous cell carcinoma is the most frequently observed histological type, while melanoma is extremely rare. Age, histology, TNM stage, tumor size, surgery and radiation are independent prognostic factors. Although marital status does not affect survival rates, married women are likely to live longer than widowed and divorced/separated cases. Age ≥80 years seems to be an important cut point in the survival of vaginal cancer. Older age (≥80 years) and melanoma have greater influences on mortality risk in early-stage disease.

Time trends in the incidence and survival of vaginal squamous cell carcinoma and high-grade vaginal intraepithelial neoplasia in Denmark - A nationwide population-based study. Gynecol Oncol 2020; 158:734-739.

Abstract
OBJECTIVE To describe trends in incidence of high-grade vaginal intraepithelial neoplasia (VaIN) and vaginal squamous cell carcinoma (SCC) in Denmark. For vaginal SCC, we also examine 5-year relative survival and mortality. METHODS All high-grade VaIN cases diagnosed 1997-2017 and vaginal SCCs during 1978-2017 were identified in two high-quality nationwide registers. Age-standardized incidence rates and average annual percentage change (AAPC) were assessed. For vaginal SCC, 5-year relative survival was calculated, and Cox regression was applied to study the effect of selected characteristics on mortality. RESULTS Altogether, 831 cases of high-grade VaIN and 721 vaginal SCCs were identified. The age-standardized incidence rate of high-grade VaIN showed no clear trend over time. However, when we stratified by age and divided the study period according to HPV vaccine licensure in Denmark (2006), the incidence of high-grade VaIN decreased significantly by 15.6% per year (95% CI: -23.2, -7.3%) after 2007 onwards among the youngest women (<30 years). For vaginal SCC, the incidence decreased from 0.5 (1978-1982) to 0.3 (2013-2017) per 100,000 woman-years. The 5-year relative survival improved over time and was 67.9% (95% CI: 54.9, 84.1%) in the most recent time period. Mortality was significantly associated with calendar year, age, and stage at diagnosis. CONCLUSIONS The overall incidence of high-grade VaIN showed no clear trend over time, but a significant decline was observed in women younger than 30 years after HPV vaccine licensure. The incidence of vaginal SCC was reduced by approximately 50% and survival after vaginal SCC improved over time.

Abstract
Aim: Our goal was the development of DNA- or peptide-based multiepitope vaccines targeting HPV E7, E6 and E5 oncoproteins in tumor mouse model. Materials & methods: After designing the multiepitope E7, E6 and E5 constructs from four types of high risk HPVs (16, 18, 31 & 45) using bioinformatics tools, mice vaccination was performed by different homologous and heterologous modalities in a prophylactic setting. Then, anti-tumor effects of the best prophylactic strategies were studied in a therapeutic setting. Results: In both prophylactic and therapeutic experiments, groups receiving homologous E7+E6+E5 polypeptide, and heterologous E7+E6+E5 DNA prime/polypeptide boost were successful in complete rejection of tumors. Conclusion: The designed multiepitope constructs can be considered as promising candidates to develop effective therapeutic HPV vaccines.

Abstract
OBJECTIVE Definitive radiation therapy (RT), using external beam RT and/or brachytherapy, is a standard treatment option for primary vaginal carcinoma. However, this treatment has poor prognosis when applied to vaginal nonsquamous cell carcinoma (non-SCC). We aimed to clarify treatment outcome and surgical safety in early-stage primary vaginal non-SCC. METHODS After receiving approval from the institutional review board, we retrospectively reviewed the clinical records and pathological samples of patients treated at our hospital between 1991 and 2018. Among 49 patients with primary vaginal carcinoma, 12 with histologically confirmed early-stage primary vaginal non-SCC were included in this study. RESULTS In total, 40% of patients with primary vaginal carcinoma treated at our hospital had primary vaginal non-SCC. The average observation time was 34 months (median 53.3 months). Three patients had local recurrence: 2 in pelvic lymph nodes and 1 in the vagina. Furthermore, 2 patients died of their disease. Five-year local control rate of stage I and stage II non-SCC was 75% and 100%, respectively. Disease-specific survival rate of stage I and stage II non-SCC was 81.8% and 100%, respectively. No major morbidity was observed. Three patients required allogeneic blood transfusion, whereas 1 underwent autotransfusion. None of the 12 patients were discharged with self-catheterization. CONCLUSION Five-year local control and disease-specific survival rates of patients surgically treated for vaginal non-SCC were favorable. Therefore, surgery could be a safe and reasonable option for early-stage primary vaginal non-SCC.

Abstract
AIM We report clinical outcomes of transarterial embolization in 19 cases of vaginal cancer. METHODS From August 2011 to October 2019, 19 patients with histologically diagnosed vaginal cancer were identified in our department. Transarterial chemotherapy and embolization was performed for all patients. Patient characteristics, treatment plans and the clinical outcomes, were recorded. RESULTS Among 19 identified cases, nine of them are squamous cell carcinoma, five of adenocarcinoma, one of adenosquamous carcinoma, two of vaginal malignant melanoma, one leiomyosarcoma and one of stromal sarcoma. Transarterial chemotherapy and embolization was successfully performed in all patients. No related complication was found after intervention treatment. Besides, eight patients received adjuvant chemotherapy, four received both adjuvant chemotherapy and radiotherapy and seven received no therapies. Four patients were cured and seven were stable during follow-up. CONCLUSION Transarterial embolization appears safe and effective for vaginal cancer, with a currently acceptable prognosis.

Abstract
INTRODUCTION The aim is to assess the outcome of patients treated for vaginal carcinoma with radiation therapy in terms of long-term tolerance and survival. MATERIALS AND METHODS This single-center retrospective study included patients with squamous cell carcinoma of the vagina treated with pelvic external beam radiation therapy (EBRT) with or without vaginal brachytherapy (VB) between 1990 and 2013. RESULTS Thirty-seven patients were included with stage I (24%), II (60%), III (8%), or IV (8%) vaginal tumors. Median age was 66 years (range 27-86 years). Median tumor size was 4 cm (range 0.7-12 cm). Seven patients underwent first intention surgery. The 37 patients received pelvic EBRT (45 Gy) with inguinal irradiation in 57% of cases. Fifteen (41%) received concurrent chemotherapy. Low-dose supplemental VB was performed in 31 patients (84%) (median dose: 20 Gy). Median follow-up was 59 months (range 7-322 months). Four patients (11%) had late grade 3-4 complications. Relapse occurred in 11 patients (30%), five of them locally. The 5-year relapse-free and cancer-specific survival rates were 68% and 76%, respectively. Surgery and concurrent chemotherapy did not seem to have an impact on the course of the disease. CONCLUSION In our experience, pelvic EBRT leads to prolonged survival with acceptable long-term toxicity in patients with squamous cell carcinoma of the vagina.

Severe Vaginal Bleeding in a Case of Renal Cell Carcinoma. Case Rep Obstet Gynecol 2019; 2019:2174051. [PMID: 31360564 PMCID: PMC6644278 DOI: 10.1155/2019/2174051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2019] [Accepted: 05/08/2019] [Indexed: 11/17/2022] Open
Abstract
Renal Cell Carcinoma (RCC) accounts for approximately 2-3% of all adult cancers and carries the highest mortality of the genitourinary cancers. Metastatic disease is seen in approximately 16% of cases and when present represents an advanced status. Metastasis of RCC to the vagina has rarely been cited in literature and when present can mimic primary vaginal cancer in clinical presentation and symptoms. Biopsy is performed to delineate the etiology and, in the presence of clear cells and certain immunohistochemistry markers, RCC needs to be included in the differential diagnosis. Treatment protocols are limited due to the rarity of the condition, with retrospective and comparative studies alongside cervical cancer treatment protocols serving as the basis. Herein, we describe a unique case of profuse vaginal bleeding secondary to vaginal metastases of RCC and discuss the relevant aspects of diagnosis and treatment.

Buchanan TR, Zamorano AS, Massad LS, Liu J, Thaker PH, Powell MA, Mutch DG, Kuroki LM. Risk of cervical and vaginal dysplasia after surgery for vulvar intraepithelial neoplasia or cancer: A 6 year follow-up study. Gynecol Oncol 2019; 155:88-92. [PMID: 31375270 DOI: 10.1016/j.ygyno.2019.07.017] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2019] [Revised: 07/11/2019] [Accepted: 07/16/2019] [Indexed: 10/26/2022]
Abstract
OBJECTIVES To estimate the frequency of abnormal surveillance cytology leading to high-grade dysplasia after surgical management for high-grade vulvar intraepithelial neoplasia (VIN) and vulvar cancer and to determine whether prior hysterectomy reduces this risk. METHODS Women who underwent surgery for high-grade VIN or vulvar cancer between 2006 and 2014 were identified retrospectively. Patients who underwent prior hysterectomy for any indication were included. Univariate and multivariate logistic regression analyses were used to identify clinical correlates of abnormal cytology after surgical treatment for VIN and vulvar cancer. RESULTS During a median follow-up for 72 months, 302 women underwent surveillance with cytologic screening after vulvar surgery including 99 (33%) women with prior hysterectomy. 75 (25%) women had abnormal cytology results. Of those, 47 (63%) were low-grade and 28 (37%) were high-grade, including 2 (3%) cases of invasive cancer. The rates of high-grade vaginal intraepithelial neoplasia (VAIN), cervical intraepithelial neoplasia (CIN), or cancer were not significantly different despite prior hysterectomy (9% VAIN 2+, 7% CIN 2+). Multivariate analysis showed that correlates of high-grade cytology following treatment for VIN or vulvar cancer included non-white race [odds radio (OR) 3.6, 95% confidence interval (CI) 1.7-7.8], prior abnormal cytology (OR 3.5, 95% CI 1.6-7.6), and immunodeficiency (OR 3.4, 95% CI 1.3-8.8). Prior hysterectomy did not significantly decrease risk of high-grade cytology (OR 0.87, 95% CI 0.5-1.6). CONCLUSIONS Women treated surgically for VIN/vulvar cancer have an 8% risk of at least high-grade dysplasia from surveillance screening and prior hysterectomy does not mitigate the risk. Extrapolating from current guidelines, we recommend surveillance cytology screening at least 6-12 months after treatment.

Abstract
Purpose This is an official guideline, published and coordinated by the Gynecological Oncology Working Group (AGO) of the German Cancer Society (DKG) and the German Society for Gynecology and Obstetrics (DGGG). Vaginal cancers are rare tumors, which is why there is very little evidence on these tumors. Knowledge about the optimal clinical management is limited. This first German S2k guideline on vaginal cancer has aimed to compile the most current expert knowledge and offer new recommendations on the appropriate treatment as well as providing pointers about individually adapted therapies with lower morbidity rates than were previously generally available. The purpose of this guideline is also to set up a register to record data on treatment data and the course of disease as a means of obtaining evidence in future. Methods The present S2k guideline was developed by members of the Vulvar und Vaginal Tumors Commission of the AGO in an independently moderated, structured, formal consensus process and the contents were agreed with the mandate holders of the participating scientific societies and organizations. Recommendations To optimize the daily care of patients with vaginal cancer: 1. Monitor the spread pattern; 2. Follow the step-by-step diagnostic workup based on initial stage at detection; 3. As part of individualized clinical therapeutic management of vaginal cancer, follow the sentinel lymph node protocol described here, where possible; 4. Participate in the register study on vaginal cancer.

Abstract
BACKGROUND Vaginal cancer is a rare disease with poor clinical outcomes and limited therapeutic options. In the United States (US), minority women and older women are disproportionately diagnosed with late-stage vaginal cancer. Sociodemographic characteristics, risk behaviors, and cooccurring conditions are linked to vaginal intraepithelial neoplasia (VaIN). The diagnosis of VaIN is more prevalent among older women and women living with HIV (WLWH). The Caribbean basin has one of the highest rates of anogenital cancers in the Western Hemisphere. In the US, vaginal infections are more prevalent among Caribbean women, and these infections contribute to higher rates of Human Papilloma Virus (HPV). Given the high rate of anogenital cancers in the Caribbean and the high rates of HPV among Caribbean women in the US, we sought to describe the occurrence of VaIN in a cohort of Black non-Hispanic WLWH. The cohort was followed by an interdisciplinary team of providers with the University of Miami, Miller School of Medicine. RESULTS Caribbean Americans were living with HIV longer and more were uninsured; more African Americans endorsed cigarette and illicit substance use. Caribbean Americans trended towards the highest grades of VaIN (VaIN 2+) at baseline, but more African Americans progressed to VaIN 2+ in subsequent biopsies. CONCLUSION In this cohort of Caribbean American and African American women living with HIV diagnosed with VaIN, Caribbean Americans had the highest grade of VaIN at baseline, but more African Americans progressed to more advanced stages of the disease.

Abstract
Vaginal cancer is rare and largely unexplored. We found here that kallikrein-related peptidase 5 (KLK5) is coordinately expressed along with other KLKs in all stratified epithelia, including vagina, pointing to potential role(s) in differentiation. Further, we propose that KLK5 could be implicated in vaginal cancer development based on the fact that Klk5-/- mice are prone to develop vaginal tumors when exposed to 7,12-dimethylbenz[a]anthracene. Nf-κb activation is markedly enhanced in Klk5-/-, leading to increased resistance to apoptosis of mutated vaginal cells. This explains the higher tumor numbers observed in Klk5-/- compared to wildtype. Thus, KLK5 may represent a putative suppressor of vaginal cancer.

Image-based multichannel vaginal cylinder brachytherapy for the definitive treatment of gynecologic malignancies in the vagina. Gynecol Oncol 2018; 150:293-299.

Abstract
PURPOSE Brachytherapy is integral to vaginal cancer treatment and is typically delivered using an intracavitary single-channel vaginal cylinder (SCVC) or an interstitial brachytherapy (ISBT) applicator. Multi-channel vaginal cylinder (MCVC) applicators allow for improved organ-at-risk (OAR) sparing compared to SCVC while maintaining target coverage. We present clinical outcomes of patients treated with image-based high dose-rate (HDR) brachytherapy using a MCVC. METHODS AND MATERIALS Sixty patients with vaginal cancer (27% primary vaginal and 73% recurrence from other primaries) were treated with combination external beam radiotherapy (EBRT) and image-based HDR brachytherapy utilizing a MCVC if residual disease thickness was 7 mm or less after EBRT. All pts received 3D image-based BT to a total equivalent dose of 70-80 Gy. RESULTS The median high-risk clinical target volume was 24.4 cm3 (interquartile range [IQR], 14.1), with a median dose to 90% of 77.2 Gy (IQR, 2.8). After a median follow-up of 45 months (range, 11-78), the 4-year local-regional control, distant control, DFS, and OS rates were 92.6%, 76.1%, 64.0%, and 67.2%, respectively. The 4-year LRC rates were similar between the primary vaginal (92%) and recurrent (93%) groups (p = 0.290). Pts with lymph node positive disease had a lower rate of distant control at 4 years (22.7% vs. 89.0%, p < 0.001). There were no Grade 3 or higher acute complications. The 4-year rate of late Grade 3 or higher toxicity was 2.7%. CONCLUSIONS Clinical outcomes of pts with primary and recurrent vaginal cancer treated definitively in a systematic manner with combination EBRT with image-guided HDR BT utilizing a MCVC applicator demonstrate high rates of local control and low rates of severe morbidity. The MCVC technique allows interstitial implantation to be avoided in select pts with ≤7 mm residual disease thickness following EBRT while maintaining excellent clinical outcomes with extended 4-year follow-up in this rare malignancy.

Abstract
Vaginal cancer is such a rare tumor that epidemiological and clinical information for it is based mainly on studies of small numbers of cases. The aim of the present study was to perform a descriptive epidemiological analysis of vaginal cancer using a significantly larger population-based dataset from the Japanese Osaka Cancer Registry.The age-standardized incidence of vaginal cancer per 1,000,000 persons, from 1976 to 2010, was calculated and examined for trends. Relative-survival analysis was applied to estimate a more up-to-date 10-year period calculation, using data from recently followed-up patients. The conditional 5-year survival of patients who survived for 0 to 5 years after diagnosis was calculated.A total of 481 cases of vaginal cancer were registered in Osaka during the 35-year period from 1976 to 2010. The age-adjusted incidence rate has significantly and consistently decreased over this time [annual percent change (APC) = -1.29, 95% confidence interval (95% CI): -0.3 ∼ -2.2]; however, due to significant population aging, the raw incidence of vaginal cancer appeared to have been increasing. The 10-year relative survival of patients with surgery-based treatments was comparable to that of radiation-based treatments, implying that surgery and radiotherapy provide similar therapeutic benefits (P = .98). The 10-year relative survival was not significantly different during the period of 1976 to 2000 compared with the period of 2001 to 2008, although there has been, in the latter period, a tendency for improvement of long-term survival, especially for survival longer than 5 years. The longer the time after diagnosis, the higher the conditional 5-year relative-survival at 0 to 4 years after diagnosis.The age-adjusted incidence of vaginal cancer has decreased since 1976. Regrettably, the 10-year survival rate did not similarly improve, and it remained stable during the period from 2001 to 2008, compared with the period from 1976 to 2000, indicating that significant work remains to be done to develop more effective vaginal cancer treatments.

Abstract
Cervical cancer accounts for about two-thirds of all cancer cases linked etiologically to Human Papilloma Virus (HPV). 15 oncogenic HPV types can cause cervical cancer, of which HPV16 and HPV18 combinedly account for about 70% of it. So, effective epitope design for the clinically relevant HPV types 16 and 18 would be of major medical benefit. Here, a comprehensive analysis is carried out to predict the epitopes against HPV types 16 and 18 through "reverse vaccinology" approach. We attempted to identify the evolutionarily conserved regions of major capsid protein (L1) as well as minor capsid protein (L2) of HPV and designed epitopes within these regions. In this study, we analyzed about 49 and 27 sequences of HPV L2 and L1 proteins respectively. Since we found that the intertype variability of L2 is higher than for L1 proteins, our analysis was emphasized on epitopes of L1 of HPV types 16 and 18. We had selected HLA-A*0201, DRB1*1501, DQB1*0602, DRB1*0401 and DQB1*0301 alleles for the prediction of T cell epitopes of L1 of HPV 16 and 18. Finally, we reported that predicted epitope sequences EEYDLQFIFQLCKITLTA, and RHGEEYDLQFIFQLCKITLTA of L1 protein of HPV 16, and LPDPNKF, PETQRLVWAC, PVPGQYDA, YNPETQRLVWAC, DTGYGAMD, PVPGQYDATK, KQDIPKVSAYQYRVFRV, RDNVSVDYKQTQLCI and YSRHVEEYDLQFIF of L1 protein of HPV 18 could be therapeutic tools for vaccine design against HPV.

Abstract
Human papillomavirus (HPV) was found to be the causative agent for cervical cancer in the 1980s with almost 100% of cervical cancer cases testing positive for HPV. Since then, many studies have been conducted to elucidate the molecular basis of HPV, the mechanisms of carcinogenesis of the virus, and the risk factors for HPV infection. Traditionally, the Papanicolaou test was the primary screening method for cervical cancer. Because of the discovery and evolving understanding of the role of HPV in cervical dysplasia, HPV testing has been recommended as a new method for cervical cancer screening by major professional organizations including the American Cancer Society, American Society for Colposcopy and Cervical Pathology, and the American Society for Clinical Pathology. In order to detect HPV infections, many sensitive and specific HPV assays have been developed and used clinically. Different HPV assays with various principles have shown their unique advantages and limitations. In response to a clear causative relationship between high-risk HPV and cervical cancer, HPV vaccines have been developed which utilize virus-like particles to create an antibody response for the prevention of HPV infection. The vaccines have been shown in long-term follow-up studies to be effective for up to 8 years; however, how this may impact screening for vaccinated women remains uncertain. In this chapter, we will review the molecular basis of HPV, its pathogenesis, and the epidemiology of HPV infection and associated cervical cancer, discuss the methods of currently available HPV testing assays as well as recent guidelines for HPV screening, and introduce HPV vaccines as well as their impact on cervical cancer screening and treatments.

Lactobacilli enhance reactive oxygen species-dependent apoptosis-inducing signaling. Redox Biol 2017; 11:715-724. [PMID: 28193594 PMCID: PMC5310163 DOI: 10.1016/j.redox.2017.01.015] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2017] [Accepted: 01/23/2017] [Indexed: 12/18/2022] Open
Abstract
H2O2-producing lactobacilli in the vaginal fluid have been suggested to play a potential tumor-preventive role in addition to the control of undesirable microorganisms. As the vaginal fluid also contains a significant concentration of peroxidase that might utilize lactobacilli-derived H2O2 as substrate for HOCl synthesis, a dominant biological role of HOCl in both natural defence systems has been postulated. Our study shows that lactobacillus-derived H2O2 per se is not likely to be beneficial for the vaginal epithelium, as it causes apoptosis nonselectively in nontransformed as well as transformed cells. However, the combination of lactobacilli and peroxidase, i.e. the situation that is actually found in vivo, leads to the conversion of H2O2 to HOCl which does not affect non-malignant cells, as these do not generate extracellular superoxide anions. In contrast, malignant cells, due to their abundant extracellular superoxide anion generation allow the generation of apoptosis-inducing hydroxyl radicals through HOCl/superoxide anion interaction. In total, our data show that the combination of H2O2 -generating lactobacilli and peroxidase causes the selective elimination of malignant cells and thus might contribute to the tumorpreventive potential of lactobacilli. These findings are in good agreement with epidemiological data. The contribution of lactobacilli in this system can be completely mimicked by H2O2-generating glucose oxidase, indicating that it is fully explained by bacterial generation of H2O2. Lactobacillus-derived H2O2 induces apoptosis in nontransformed and transformed cells. MPO converts H2O2 into HOCl that exerts a selective apoptosis-inducing effect on malignant cells. Extracellular superoxide anions of malignant cells are crucial for selective apoptosis induction. A model for the tumor protective role of lactobacilli in the presence of peroxidase is presented.

[PMID: 27780076 PMCID: PMC5124511 DOI: 10.1016/j.canep.2016.10.008] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2016] [Revised: 10/09/2016] [Accepted: 10/16/2016] [Indexed: 12/28/2022]
Abstract
INTRODUCTION HPV attributable cancers are the second most common infection-related cancers worldwide, with much higher burden in less developed regions. There are currently no country-specific estimates of the burden of these cancers in Nigeria just like many other low and middle income countries. METHODS In this study, we quantified the proportion of the cancer burden in Nigeria that is attributable to HPV infection from 2012 to 2014 using HPV prevalence estimated from previous studies and data from two population based cancer registries (PBCR) in Nigeria. We considered cancer sites for which there is strong evidence of an association with HPV infection based on the International Agency for Research on Cancer (IARC) classification. We obtained age and sex-specific estimates of incident cancers and using the World Standard Population, we derived age standardized incidence (ASR) rates for each cancer type by categories of sex, and estimated the population attributable fractions (PAF). RESULTS The two PBCR reported 4336 new cancer cases from 2012 to 2014. Of these, 1627 (37.5%) were in males and 2709 (62.5%) in females. Some 11% (488/4336) of these cancers were HPV associated; 2% (38/1627) in men and 17% (450/2709) in women. Of the HPV associated cancers, 7.8% occurred in men and 92.2% in women. The ASRs for HPV associated cancers was 33.5 per 100,000; 2.3 and 31.2 per 100,000 in men and women respectively. The proportion of all cancers attributable to HPV infection ranged from 10.2 to 10.4% (442-453 of 4336) while the proportion of HPV associated cancers attributable to HPV infection ranged from 90.6% to 92.8% (442-453 of the 488 cases). In men, 55.3% to 68.4% of HPV associated cancers were attributable to HPV infection compared to 93.6% to 94.8% in women. The combined ASR for HPV attributable cancers ranged from 31.0 to 31.7 per 100,000. This was 1.4 to 1.7 per 100,000 in men and 29.6 to 30.0 per 100,000 in women. In women, cervical cancer (n=392, ASR 28.3 per 100,000) was the commonest HPV attributable cancer, while anal cancer (n=21, ASR 1.2 per 100,000) was the commonest in men. CONCLUSIONS HPV attributable cancers constitute a substantial cancer burden in Nigerian women, much less so in men. A significant proportion of cancers in Nigerian women would be prevented if strategies such as HPV DNA based screening and HPV vaccination are implemented.

Abstract
ObjectivesThe objective of our present study was to evaluate the efficacy of radical vaginectomy with or without radical hysterectomy in patients with International Federation of Gynecology and Obstetrics stage I and II vaginal cancers.Materials and MethodsA retrospective study was carried out on 11 patients aged 35 to 78 years. All the patients underwent radical surgery for vaginal cancer from April 2010 till June 2015. Kaplan-Meier analyses were used to calculate the disease-free survival and overall survival at 12 months.ResultsThe mean age of patients was 53.2 years. Ten patients were with International Federation of Gynecology and Obstetrics stage I, whereas one had stage II vaginal cancer. The histology was squamous cell cancer in 9 patients and small cell neuroendocrine cancer in 2 patients. The lesion was confined to the upper two third of the vagina in 8 cases, and the lower one third was involved in 3 cases. All the patients underwent radical surgery. Lymph node dissection was done in 9 patients out of whom lymph nodes were positive in 3 patients. Two patients had positive margins. Adjuvant treatment was given to patients with positive margins or positive nodes. Five patients did not require any adjuvant treatment, and 1 patient defaulted adjuvant treatment. One patient developed vesicovaginal fistula. Over a follow-up period ranging from 5 to 67 months, local recurrence developed in 1 patient, whereas no patient died of disease. One patient was lost to follow-up at 15 months. The 12-month disease-free survival was 88.9%, and 12-month overall survival was 100%.ConclusionsStage I and selected stage II vaginal cancer patients have good outcomes in terms of survival and local tumor control if managed judiciously by initial surgery followed by selective adjuvant therapy.

Abstract
PURPOSE To compare clinical outcomes of image-based versus non-image-based interstitial brachytherapy (IBBT) for vaginal cancer. METHODS AND MATERIALS Of 72 patients with vaginal cancer treated with brachytherapy (BT), 47 had image guidance (CT=31, MRI=16) and 25 did not. Kaplan-Meier (KM) estimates were generated for any recurrence, local control (LC), disease-free interval (DFI), and overall survival (OS) and Cox models were used to assess prognostic factors. RESULTS Median age was 66 and median follow-up time was 24months. Median cumulative EQD2 dose was 80.8Gy in the non-IBBT group and 77Gy in the IBBT group. For non-IBBT versus IBBT, the 2-year KM LC was 71% vs. 93% (p=0.03); DFI was 54% vs. 86% (p=0.04); and OS 52% vs. 82% (p=0.35). On multivariate analysis, IBBT was associated with better DFI (HR 0.24, 95% CI 0.07-0.73). Having any 2 or more of chemotherapy, high-dose-rate (HDR) BT or IBBT (temporally correlated variables) significantly reduced risk of relapse (HR=0.33, 95% CI=0.13-0.83), compared to having none of these factors. CONCLUSION Over time, the use of chemotherapy, HDR, and IBBT has increased in vaginal cancer. The combination of these factors resulted in the highest rates of disease control. Image-guided brachytherapy for vaginal cancer patients maximizes disease control.

Abstract
OBJECTIVE The prognosis and vaginal disease control rate after treatment with radiotherapy or concurrent chemoradiotherapy (CCRT) are reported to be worse for primary non-squamous cell carcinoma (non-SCC) of the vagina than for squamous cell carcinoma (SCC) of the vagina. Our objective was to examine the clinicopathological characteristics of primary non-SCC of the vagina and suggest an appropriate treatment strategy. MATERIALS AND METHODS In a retrospective chart review, we identified patients with primary vaginal cancer who were treated in our hospital between 1990 and 2013. Twelve patients with histologically diagnosed non-SCC were identified. None of these cases was associated with in utero diethylstilbestrol exposure. Clinical data, including patient characteristics, stage, treatment outcome, and the site of recurrence, were recorded. RESULTS The 12 identified cases included 5 of clear cell carcinoma, 3 of adenocarcinoma, 2 of adenosquamous carcinoma, 1 of carcinosarcoma, and 1 of mucinous adenocarcinoma. The most common location of the tumor was the upper one third of the vagina (56%). Initial treatment involved surgery in 8 patients. Among them, 4 received adjuvant chemotherapy, 3 received adjuvant radiotherapy, and 1 received neither. The initial treatment among the remaining 4 patients was CCRT in 1, neoadjuvant chemotherapy in 2 (followed by CCRT or surgery), and best supportive care in 1. The last 3 patients had lung metastasis. Six patients experienced recurrence, including vaginal recurrence in 2 patients and lymphatic spread in 4 patients. Five of these 6 patients experienced hematogenous metastasis. CONCLUSIONS Despite the absence of in utero diethylstilbestrol exposure in our cases, clear cell adenocarcinoma accounted for 41.7% (5/12) cases. A favorable local control rate was achieved in all 12 cases, but the incidence of distant metastasis, especially to the lung, was high. Prevention of distant metastasis may be the key to treating patients with non-SCC of the vagina.

Abstract
BACKGROUND The role of p16INK4A expression in uterine cervix cancer is well established. In the remaining female lower genital tract cancers, the importance of p16INK4A up-regulation is less clear. In our study, we analyzed the role of p16INK4A expression and HPV infection in carcinomas of the vulva and the vagina in Tunisian women. MATERIALS AND METHODS We conducted a retrospective study of 30 carcinomas including 15 vulvar squamous cell carcinomas (SCCs) and 15 vaginal SCCs. Immunohistochemistry was used to determine p16INK4A expression. HPV detection and typing was by in situ hybridization. RESULTS p16INK4A expression was detected in 86.7% of vaginal SCCs with a strong and diffuse immunostaining in 60% of cases, and also in 73.3% of vulvar SCCs with focal immunoreactivity in 53.3% The association between p16INK4A expression and HPV infection was significant in vaginal SCCs (p=0.001) but not vulvar SCCs (p>0.05). CONCLUSIONS p16INK4A expression could be used as a useful marker for HPV positivity in vaginal SCCs similar to that described in uterine cervix cancers. However, our data support the presence of 2 different mechanisms for p16INK4A expression in HPV-related and HPV-unrelated vulvar carcinomas.

Abstract
OBJECTIVE To evaluate the mortality outcomes of vaginal sarcomas in a large cohort compared with vaginal squamous cell and adenocarcinomas. METHODS Women with primary invasive vaginal sarcomas, squamous cell carcinomas, and adenocarcinomas diagnosed between 1988 and 2010 were identified within the National Cancer Institute's Surveillance, Epidemiology, and End Results database. Parametric and nonparametric methods were used to compare the demographic and clinical characteristics of women among the three tumor types as well as between sarcoma histologic subtypes. Overall and cancer-specific mortality outcomes were examined using Kaplan-Meier and multivariable Cox proportional hazards models. RESULTS The final cohort consisted of 3,121 patients with vaginal squamous cell carcinoma, 720 patients with adenocarcinoma, and 221 patients with sarcoma. Compared with women with squamous cell carcinoma and adenocarcinoma, patients diagnosed with vaginal sarcomas tended to be younger, have larger tumors with less regional extension and lymph node positivity, and be treated primarily with surgery without radiation. In unadjusted analysis, 5-year mortality rates border 30% for all three histologies. After adjusting for other prognostic factors including use of radiation and surgery, patients with vaginal sarcomas had a 69% greater risk of cancer-related mortality compared with patients with squamous cell carcinoma (hazard ratio 1.69, 95% confidence interval 1.26-2.26). Although sarcoma histology failed to associate with mortality risk, age, tumor extension and metastasis, and surgery were poor prognostic factors. CONCLUSION Primary vaginal sarcomas are aggressive neoplasms with different presenting characteristics and increased adjusted risk of mortality compared with squamous cell and adenocarcinoma subtypes. LEVEL OF EVIDENCE III.

Abstract
Both primary and secondary prevention of cervical cancer are now available. Immunizations against human papillomavirus (HPV) types 16 and 18 have the potential to prevent 70% of cancers of the cervix plus a large percentage of other lower anogenital tract cancers. Screening guidelines were recently changed to recommend cotesting with cytology plus an HPV test. The addition of HPV testing increases the sensitivity and negative predictive value of screening over the Papanicolaou (Pap) test alone.

Abstract
OBJECTIVE To assess the value of vaginal screening cytology after hysterectomy for benign disease. METHODS This cross-sectional study used cytology audit data from 2,512,039 screening tests in the metropolitan region of Campinas from 2000 to 2012; the object was to compare the prevalence of abnormal tests in women who had undergone a hysterectomy for benign diseases (n=53,891) to that of women who had had no hysterectomy. Prevalence ratios (95% confidence intervals, 95% CI) were determined, and chi-square analysis, modified by the Cochrane-Armitage test for trend, was used to investigate the effects of age. RESULTS The prevalence of atypical squamous cells (ASC), low-grade squamous intraepithelial lesion (LSIL), and high-grade squamous intraepithelial lesion or squamous-cell carcinoma (HSIL/SCC) was 0.13%, 0.04% and 0.03%, respectively, in women who had undergone hysterectomy, and 0.93%, 0.51% and 0.26% in women who had not undergone hysterectomy. The prevalence ratios for ASC, LSIL and HSIL/SCC were 0.14 (0.11-0.17), 0.08 (0.06-0.13) and 0.13 (0.08-0.20), respectively, in women with a hysterectomy versus those without. For HSIL/SCC, the prevalence ratios were 0.09 and 0.29, respectively, for women <50 or ≥50 years. The prevalence rates in women with a previous hysterectomy showed no significant variation with age. CONCLUSION The prevalence rates of ASC, LSIL and HSIL/SCC were significantly lower in women with a previous hysterectomy for benign disease compared with those observed in women with an intact uterine cervix. This study reinforces the view that there is no evidence that cytological screening is beneficial for women who have had a hysterectomy for benign disease.

Abstract
INTRODUCTION Recent epidemiologic studies have suggested that the incidence of noncervical cancers associated with human papillomavirus (HPV) is increasing. We assessed temporal, age-specific and sex-specific changes in the incidence of HPV-associated cancers in a population-based study. METHODS We used the Alberta Cancer Registry, a registry of all cancers diagnosed in the province of Alberta, Canada, to identify patients with cancers of the oropharynx, cervix, vulva, vagina, anus and penis (cancers associated with HPV) between Jan. 1, 1975, and Dec. 31, 2009. We estimated the age-standardized incidence of each cancer by sex- and age-specific group and assessed the annual percentage change using joinpoint regression. RESULTS The age-standardized incidence of oropharyngeal cancers increased for each 5-year interval of the study period among men (annual percentage change 3.4, p < 0.001) and women (annual percentage change 1.5, p = 0.009). For anal cancers, the age-standardized rates increased among women (annual percentage change 2.2, p < 0.001) and men (annual percentage change 1.8, p = 0.008). The age-standardized incidence of cervical cancer increased with age, reaching an annual percentage change of -3.5 among women aged 75-84 years (p = 0.04). The rates of other HPV-associated cancers (vulvar, vaginal and penile) showed little change. INTERPRETATION Our findings showed increases in the incidence of the HPV-associated cancers of the oropharynx and anus among men and women, and increases in cervical cancer among younger women. The incidence of HPV-related cancers in younger age groups should continue to be monitored. Programs to prevent HPV infection, such as vaccination, should be considered for males as well as females.

Abstract
OBJECTIVE To describe the human papillomavirus (HPV) genotype distribution in invasive vaginal cancers diagnosed before the introduction of the HPV vaccine and evaluate if survival differed by HPV status. METHODS Four population-based registries and three residual tissue repositories provided formalin-fixed, paraffin-embedded tissue from microscopically confirmed primary vaginal cancer cases diagnosed between 1994 and 2005 that were tested by L1 consensus polymerase chain reaction with type-specific hybridization in a central laboratory. Clinical, demographic, and all-cause survival data were assessed by HPV status. RESULTS Sixty cases of invasive vaginal cancer were included. Human papillomavirus was detected in 75% (45) and 25% (15) were HPV-negative. HPV 16 was most frequently detected (55% [33/60]) followed by HPV 33 (18.3% [11/60]). Only one case was positive for HPV 18 (1.7%) Multiple types were detected in 15% of the cases. Vaginal cancers in women younger than 60 years were more likely to be HPV 16- or HPV 18-positive (HPV 16 and 18) than older women, 77.3% compared with 44.7% (P=.038). The median age at diagnosis was younger in the HPV 16 and 18 (59 years) group compared with other HPV-positive (68 years) and no HPV (77 years) (P=.003). The HPV distribution did not significantly vary by race or ethnicity or place of residence. The 5-year unadjusted all-cause survival was 57.4% for women with HPV-positive vaginal cancers compared with 35.7% among those with HPV-negative tumors (P=.243). CONCLUSION Three fourths of all vaginal cancers in the United States had HPV detected, much higher than previously found, and 57% could be prevented by current HPV vaccines.

Abstract
BACKGROUND Improved parental awareness of human papillomavirus (HPV) vaccines could increase uptake of vaccines early in the life course, thereby reducing adolescents' later risk for HPV infection and cancer. As such, we sought to determine factors related to parental awareness of HPV vaccines, using a nationally representative population-based sample. METHODS We examined data on 5735 parents of preadolescents and adolescents aged 8 to 17 years from the 2010 National Health Interview Survey. Parents were asked if they had ever heard of HPV vaccines or shots. Multivariable logistic regression analyses were used to examine the odds of parental awareness of HPV vaccines, controlling for relevant covariates. RESULTS Most US parents (62.6%) heard of HPV vaccines. Multivariable results revealed parents of children who were older, female, and insured were more likely to have heard of HPV vaccines; parents who were female, white (non-Hispanic), English speakers, born in the United States, married or living with a partner, more educated, and had higher income were also more likely to be aware of HPV vaccines. Notably, parents of children who had a well-child checkup in the last 12 months were significantly more likely to have heard of HPV vaccines (odds ratio, 1.23; 95% confidence interval, 1.04-1.46). CONCLUSIONS Given the significant disparities in parental awareness of HPV vaccines, improving access to preventive pediatric health care could offer an opportunity to increase parental awareness. In addition, public health efforts that provide culturally sensitive information in a variety of languages may be an effective way to reach vulnerable groups.

Surveillance for recurrent cancers and vaginal epithelial lesions in patients with invasive cervical cancer after hysterectomy: are vaginal cytology and high-risk human papillomavirus testing useful?

Abstract
OBJECTIVES To examine whether women who have had a hysterectomy for cervical cancer may be at an increased risk of vaginal epithelial lesions. METHODS We studied 147 patients with invasive cervical carcinoma (76 squamous cell carcinomas [SCCs], 60 adenocarcinomas [ADCs], and 11 adenosquamous cell carcinomas) who were treated by hysterectomy and had vaginal pathologic follow-up for a mean period of 43.3 months. RESULTS Of the patients, 15.0% (22/147) developed vaginal intraepithelial neoplasia (VAIN) or recurrence after hysterectomy, including two recurrent carcinomas and eight high-grade VAINs. More important, these high-grade VAINs or recurrent carcinomas were detected only in patients with cervical SCC within the first two years after hysterectomy but not in patients with cervical ADC. Eleven (23.4%) of 47 patients had at least one positive high-risk human papillomavirus (hrHPV) testing result during the follow-up period, and VAIN was detected in 54.5% (6/11) of patients with an hrHPV-positive result compared with 16.7% (6/36) with an hrHPV-negative result. CONCLUSIONS Our results indicate that women with cervical cancer are at an increased risk of VAIN besides recurrence, and women with cervical SCC are more prone to high-grade VAIN/recurrence, especially within the first two years after hysterectomy. The significantly increased detection rate of VAINs/recurrence in the hrHPV-positive group suggests vaginal cytology and HPV cotesting might be the preferred method for surveillance in these women.

Abstract
OBJECTIVE Report and discuss the management of the primitive vaginal cancer in elderly adults at a single institute. PATIENTS AND METHODS Data from patients more than 70 year-old treated for a primitive vaginal cancer at the Institut de Cancérologie de la Loire Lucien-Neuwirth was retrospectively collected. RESULTS From August 1999 to January 2009, 9/24 patients treated for a primitive vaginal cancer had more than 70 year-old. The median age was 81 years (7-94 years). Most patients had a performance status less or equal to 1 (n=6), a squamous cell carcinoma (n=7) and a FIGO stage less or equal to II (n=6). All patients were treated with 3D external beam radiation, 3 received concurrent chemotherapy, 3 had a supplementary brachytherapy, and 6 had a colpohysterectomy. Among 7 evaluable patients, there were 4 complete responses, 2 partial responses and one progression. Main acute toxicities were gastrointestinal (n=5), urinary (n=3), general (n=3) and cutaneous (n=2). Three patients experienced late toxicities. Four patients had a local recurrence after a mean delay of 10.8 months. At last news, 4 patients were still alive and 4/5 deaths were related to the cancer. All (n=3) patients who received the combination of radiotherapy - brachytherapy were alive and disease-free. Median overall survival was 18 months. DISCUSSION AND CONCLUSIONS Primitive vaginal cancers are rare and aggressive tumours. Our results suggested the feasibility of the combination of radiotherapy and brachytherapy for elderly patients. Prospective trials remain needed to better define and validate the optimal strategy, especially in elderly adults.

Abstract
OBJECTIVE The purpose of this study was to review a large cohort of patients with vaginal intraepithelial neoplasia (VAIN) and to analyze the epidemiology and outcomes with various treatment modalities. STUDY DESIGN A retrospective chart review was performed that encompassed patients who were treated for VAIN at a single center from 1990-2007. Demographics, disease characteristics, referring cytology, and histologic information were recorded. Primary outcome was recurrence or progression to carcinoma. Statistical analyses were performed with statistical software. RESULTS One hundred sixty-three women were included in the study: median age, 50 years (range, 21-84 years); white, 87%; current or previous smokers, 35%. At the time of diagnosis, 23% of the women had VAIN1; 37% of the women had VAIN2, and 35% of the women had VAIN3. Referral Papanicolaou smear results of high-grade squamous intraepithelial lesion or atypical glandular cells revealed VAIN2 or VAIN3 in 89% of cases (P = .0019) vs 53% of cases with low-grade squamous intraepithelial lesion. The median follow-up period was 18 months (range, 1-194 months). VAIN1 was observed in 70% of cases; 71% of patients who were treated for VAIN1 had recurrence or progression. VAIN2 was treated in 77% of patients; 53% of those who were treated had recurrence or progression. VAIN3 was treated in 94% of cases; 31% of them had recurrence or progression. Risk of recurrence was not correlated to VAIN type (P = .3). Six carcinomas were discovered in patients with VAIN2 and VAIN3. Median time to progression was 17 months for VAIN1, 11 months for VAIN2, and 11 months for VAIN3 (P = .036). CONCLUSION Despite the subtype, VAIN often recurs but does so more quickly with higher grade dysplasia.

An opportunity for cancer prevention during preadolescence and adolescence: stopping human papillomavirus (HPV)-related cancer through HPV vaccination. J Adolesc Health 2013; 52:S60-8. [PMID: 23298993 PMCID: PMC3990258 DOI: 10.1016/j.jadohealth.2012.08.011] [Citation(s) in RCA: 37] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2012] [Revised: 07/30/2012] [Accepted: 08/27/2012] [Indexed: 01/16/2023]
Abstract
OBJECTIVE We conducted a descriptive study of the correlates of refusal and acceptance of human papillomavirus (HPV) vaccination by rural parents of preadolescent and adolescent children. We hypothesized that the correlates of parents who allow their children aged 9 to 13 years to get the HPV vaccine and those of parents who do not allow vaccination would differ significantly. METHODS This cross-sectional study was implemented during the school years 2009-2011 in the elementary and middle schools of three rural counties in Georgia. Parents were recruited at school functions to complete an anonymous validated survey. RESULTS Parents who chose to vaccinate their children or intended to vaccinate were twice as likely to be from a race other than African American and 2.7 times more likely to have a religion other than Baptist. Using stepwise logistic regression and after adjustment for race and religion, we found that parents who had vaccinated or intended to vaccinate had significantly higher scores on perceived barriers (1.02 times more likely to vaccinate) and lower scores on perceived benefits (1.01 times more likely to vaccinate) (model p < .001). CONCLUSIONS The results suggest that healthcare providers in rural areas can increase HPV vaccine uptake and reduce HPV-related cancers by using a multifaceted approach to educating their patients within the context of the patients' cultural values, geographic location, and economic situation. Such an approach could dispel misinformation and increase vaccine uptake.
