Abstract
INTRODUCTION Despite the wide-spread availability of cervical cancer prevention and screening programs in developed countries, the morbidity and mortality rates of cervical cancer in Zimbabwe are still very high. Limited resources as well as the high HIV prevalence are contributors to the high burden of cervical cancer. This paper aims to analyse the policies, frameworks and current practices in the management of cervical cancer in Zimbabwe. METHODS A review of national documents and published literature on cervical cancer prevention, screening, treatment and knowledge in Zimbabwe was done. Informal interviews were conducted to assess the practices of cervical cancer management. RESULTS Through strategic collaboration, a pilot for the HPV vaccination program is underway. The VIAC national cervical cancer screening program is being adopted into the current healthcare system. With regards to the treatment of precancerous lesions we found that the "see and treat" program has been implemented in colposcopy clinics. In addition, there are two multidisciplinary cancer treatment clinics installed in two central public hospitals. The general knowledge and understanding of cervical cancer is poor in Zimbabwe. CONCLUSION Limitations in resources, infrastructure, manpower, delays in treatment and patient knowledge play a role in the high morbidity and mortality of cervical cancer in Zimbabwe. The Ministry of Health needs to increase funding to expedite the availability of HPV vaccine and screening programs. Community engagement initiatives to raise awareness on cervical cancer should be established to provide education on how to prevent the development of cervical cancer, as well as promote screening for early detection.

Abstract
INTRODUCTION Vaginal intraepithelial neoplasia (VAIN) is a pre-malignant lesion, potentially leading to vaginal cancer. It is a rare disease, representing less than 1% of all intraepithelial neoplasia of the female genital tract. Similar to cervical intraepithelial neoplasia (CIN), there are three different grades of VAIN. VAIN 1 is also known as a low-grade squamous intraepithelial lesion (LSIL), whereas VAIN 2 and VAIN 3 both represent high-grade squamous intraepithelial lesions (HSIL). Risk factors for the development of VAIN are similar to those for cervical neoplasia, i.e. promiscuity, starting sexual activity at an early age, tobacco consumption and infection with human papillomavirus (HPV). However, compared to other intraepithelial neoplasia such as CIN or VIN (vulvar intraepithelial neoplasia), there still is little understanding about the natural course of VAIN and its capacity for pro- or regression. Furthermore, there is controversial data about the HPV detection rate in VAIN lesions. PATIENTS AND METHODS 67 patients with histologically confirmed VAIN, who were diagnosed between 2003 and 2011 at the University Women´s Hospital of Heidelberg Germany, were included in this study. The biopsies of all participating patients were subjected to HPV genotyping. GP-E6/E7 Nested Multiplex PCR (NMPCR) was used to identify and genotype HPV. Eighteen pairs of type-specific nested PCR primers were assessed to detect the following "high-risk" HPV genotypes: 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66 and 68, as well as the "low-risk" genotypes 6/11, 42, 43 and 44. The data was analyzed with the software SAS (Statistical Analysis System). RESULTS All 67 cases were eligible for DNA analysis. The median age was 53 years. The largest group with 53% (n = 36) was formed by women, who were first diagnosed with VAIN between the age of 41 to 60 years. 50% (n = 37) of the patients presented a VAIN in the upper 1/3 of the vagina. 58 (87%) were diagnosed with HSIL (VAIN). The median age in patients with LSIL (VAIN) was 53 years and in patients with HSIL (VAIN) 53.5 years. 12 women (18%) had an immunosuppression. HPV positivity was confirmed in 37 patients (55%). Except for a single patient, who had a triple infection with HPV types 6/11, 16 and 68, only infections with one single HPV genotype were detected. An infection with the HPV genotypes 31, 39, 45, 51, 58, 59, 66, 42, 43 and 44 couldn't be found in any of the patients. In 28 patients with diagnosed VAIN, an infection with HPV 16 could be shown, 24 (86%) of them were diagnosed with a HSIL (VAIN). 16 (24%) women presented condylomata and 13 of them (81%) had a positive HPV status. However, only 47% of the women without condylomata presented a positive HPV status, resulting in a significant correlation (p = 0.0164) between condylomata and HPV infection. In 28 of all 67 patients (42%), recurrence of the neoplasia occurred. CONCLUSION HPV 16 is the main virus-type to be associated with the development of a VAIN. Also, HPV 16 infection, VIN or condylomata acuminata in the past medical history seemed to be significant factors for early relapse.

Abstract
OBJECTIVE Immunocompromised patients are at increased risk of developing preinvasive lesions of the lower genital tract. There are a limited number of studies on vulvar intraepithelial neoplasia (VIN) in HIV-positive women. We aimed to review the clinical presentation of VIN, management and survival outcomes in this group of patients. DESIGN Observational cohort study. METHODS Data was collected from women diagnosed with VIN at the Hospital Vall d'Hebron between September 1994 and October 2011. The main outcome measures were recurrence-free survival (RFS) and progression-free survival (PFS). Risk factors for recurrence and progression were assessed using univariate and multivariate analyses. RESULTS Thirty-seven out of 107 women were HIV positive (34.6%). The median follow-up time was 32 (range 12-179) months. Compared with the HIV-negative group, HIV-positive women were younger (median age 37 vs. 44 years, P = 0.003) and presented with multifocal and multicentric disease more frequently (63.6 vs. 22.2% and 84.8 vs. 43.3%, respectively, P < 0.0001). RFS and PFS were lower in the HIV-positive group (42.4 vs. 71.4% P = 0.043 and 69.7 vs. 95.2% P = 0.006, respectively). RFS was significantly associated to multicentric and multifocal disease on multivariate analysis. PFS was associated to HIV infection on univariate analysis. CONCLUSION HIV-positive women are at increased risk of developing VIN and frequently present at a younger age with multifocal and multicentric disease. They have shorter RFS and PFS compared with HIV-negative women. Close surveillance of the lower genital tract is mandatory to enable early recognition and treatment of any suspicious lesions. Close follow-up after treatment of VIN is essential to exclude early recurrence or progression.

Abstract
UNLABELLED Background Cervical cancer is preventable through screening, and HIV treatment guidelines recommend that all HIV-infected women receive cervical cancer twice during the year after HIV diagnosis and annually thereafter. Different immunohistochemical markers have been studied to highlight cervical intraepithelial lesions of low and high grade, the most widely used being p16. Recent studies have shown that insulin-like growth factor mRNA binding protein 3 (IMP3) plays a role in the development of invasive squamous cell carcinoma from cervical dysplasia, both in histology and in liquid-based cytology. METHODS We evaluated the clinical significance of the immunohistochemical expression of IMP3 and p16 in histological samples of cervical intraepithelial neoplasia from 56 samples of HIV-positive and 30 samples of HIV-negative patients. RESULTS A significant difference was found in IMP3 and p16 protein expression between HIV-positive and HIV-negative specimens. All cases of HIV-positive low grade squamous intraepithelial neoplasia (L-SIL) with IMP3 expression progressed in high grade (H)-SIL. However, the HIV-positive patients with IMP3-negative L-SIL remained stable or had a negative follow up. The L-SIL of HIV-negative patients with IMP3 protein expression had an uneventful follow up. IMP3-positive H-SIL recurred with low- or high-grade dysplasia during follow up after conisation in both populations. All IMP3-negative L-SIL and H-SIL had negative pap tests at follow up. CONCLUSIONS In HIV-positive cases, IMP3 showed a higher sensitivity than p16 in identifying patients at risk of progression and recurrence.

Abstract
Background: Female genital tract malignancy is common in our low resource setting. Options now exist for prevention, detection, treatment, and palliative care for the wide spectrum of female genital tract malignancies. Women will continue to die from these cancers unless health professionals and civil society adopt means to control female genital tract cancers in our low resource setting. Aim: The objective was to determine the frequency and patterns of female genital tract malignancy at the University of Nigeria Teaching Hospital (UNTH), Enugu, Nigeria. Materials and Methods: A 6-year retrospective study of female genital tract malignancies was conducted at the UNTH, Enugu. The case notes of patients admitted for female genital tract malignancy between January 1, 2003 and December 31, 2008 were retrieved from the medical records and cancer registry of the University of Nigeria Teaching Hospital, Enugu and relevant data were extracted. The data were analyzed using SPSS version 12 (SPSS Inc., Chicago, IL, USA) and the results expressed in descriptive statistics by simple percentages. Results: One hundred and sixty six (166) cases of genital malignancies were recorded during the 6-year review. Majority of the patients were in the fifth and sixth decades of life. Cancer of the cervix accounted for 66.3% (110/166) followed by ovarian cancer 21.1% (35/166). The other tumors seen during the period were tumors involving corpus uteri 9% (15/166) and vulva 3.6% (6/166). Tumors of fallopian tube and vagina were not seen during the study period. Conclusion: Despite the preventable nature of cancer of cervix, it remained the most common female genital tract malignancy in Enugu, South-East Nigeria. In our low resource setting in the developing countries, education and public enlightenment on the importance of routine screening and treatment of premalignant lesions of the cervix are necessary tools to reduce the incidence and mortality of cervical cancer.

Abstract
OBJECTIVES Persistent human papillomavirus (HPV) infections can cause intraepithelial neoplasia of the lower genital tract. Immune-compromised women have higher rates for all lower genital tract intraepithelial neoplasia. We wish to study the distribution of genital intraepithelial neoplasia in women with and without an immune system. METHODS The study consisted of 343 women with an abnormal genital lesion or cervical cytology who were referred to a gynecologic oncologist. All patients underwent vulva, vaginal, cervical and anal colposcopy. Any lesion detected was biopsied. Demographic and medical data were collected. The Chi-square test was used to determine the relationship between immunosuppression status and various variables, including sites of intraepithelial neoplasia. RESULTS Immune-compromised women (N = 33) are more likely than immune-competent women (N = 310) to have intraepithelial neoplasia of the vulva (p < 0.05) and vagina (p < 0.05), but not more likely to have intraepithelial neoplasia of the anus or cervix. Immune-compromised women are more likely than immune-competent women to have multifocal intraepithelial neoplasia (p < 0.001). In addition, immune-compromised women are more likely to have higher grade disease of the vulva and vagina (p < 0.05), and no more likely to have higher grade disease on the cervix or anus than immune-competent women. CONCLUSION Women with conditions suppressing the immune system are at higher risk for HPV-related disease outside of the cervix and for worse HPV-related diseases than immune-competent women. This study highlights the need for vigilant evaluation of the complete lower genital tract in women with immune-compromised systems.

Abstract
Vulval squamous cell carcinoma is relatively rare; however, up to 20% of women have significant vulval symptoms during their lifetime. Formal screening programmes for vulval disease have not been established. The evidence for the use of vulval cytology and vulvoscopy is reviewed. No randomised-controlled trials have compared follow-up regimens, and although a few consensus documents have been published, formal guidelines are lacking in Grade A evidence. With increasing pressure on healthcare resources, the possibility of identifying high-risk groups to optimise the use of follow up in specialist clinics is explored. Vulval disease is uncommon and there is no evidence that screening would decrease incidence. If high-risk groups can be identified, follow up should take place in specialised vulval clinics with experienced clinicians who are trained in vulval disease. Women with uncomplicated vulval conditions should be discharged to patient-initiated follow up or primary care. Central to the reduction of mortality and morbidity is increased awareness of vulval conditions among women and improved education of healthcare professionals, with particular understanding of the importance of physical examination.

Abstract
PURPOSE HPV associated cervical transformation is characterized by well-defined steps, including persistent HPV infection and deregulated oncogene expression. Recent studies have suggested that a number of lower genital tract lesions are clonally related to cervical lesions. In the current study, HPV infections and oncogene expression were assessed in a large series of patients with multicentric lower genital tract disease to analyze the transformation steps in extracervical disease. METHODS One hundred and thirty biopsies of 52 women treated for multicentric synchronous or metachronous lower genital tract intraepithelial neoplasias were collected. Up to seven multicentric specimens taken from one patient were studied with a maximum follow up of 20 years. HPV typing and p16(ink4a) immunostaining was performed. RESULTS HPV DNA was present in 121 of 130 specimens (93%). HPV16 was frequently found in VIN, VaIN and AIN (73, 60 and 77%, respectively), whereas only 37% of CIN were HPV16 positive. Infections with identical HPV types in multicentric lesions were diagnosed in 46% of the HPV positive patients. p16INK4a expression was negative in the nine HPV negative lesions whereas about 90% of the high grade lesions showed diffuse p16 staining. CONCLUSION Our findings indicate that multicentric lower genital tract disease evolves through different pathways. Some cases were related to a high susceptibility towards HPV infections, while others exhibited features of clonal propagation of transformed cervical cell clones. The clinical management of the latter group is particularly challenging, because malignant cell clones can persist over a long time course.

Abstract
BACKGROUND Squamous intraepithelial lesions are more prevalent in women infected with the human immunodeficiency virus (HIV) compared with immunocompetent women. Loop electrosurgical excision procedure (LEEP) is commonly used to treat squamous intraepithelial lesions because it may be performed as an outpatient procedure with minimal blood loss and a low complication rate. CASE We report a major infectious post-LEEP complication in an HIV-infected female who had an uneventful LEEP in which a cellulose hemostatic agent was used. Despite the severity of the infection, she was successfully treated with a minor surgical procedure along with broad antibiotic coverage. CONCLUSION Although a cellulose hemostatic agent contaminated with perineal secretions may have served as a nidus for infection, use of perioperative antibiotics or cervical cleansing should be considered to prevent sepsis in immunocompromised hosts.

Abstract
PURPOSE OF REVIEW We review the recent literature on anogenital neoplasms in AIDS, with emphasis on cancers associated with HPV infection. Immune reactivity to HPV as well as novel immunotherapeutic and preventative strategies are discussed. RECENT FINDINGS Many AIDS-associated neoplasms are associated with HPV infection. Whether cervical cancer is truly an AIDS-associated neoplasm has recently been questioned, while the association of anal cancer with AIDS in both males and females is more convincing. Recent reports cast doubt on the efficacy of HAART therapy for HPV-induced anogenital neoplasms, despite efficacy in improving disease caused by other infectious agents. We include here new data on humoral and cellular immune responses to HPV. VLP serology has been reported to be associated with outcome of cervical cancer. VLP seropositivity has been reported to be a favorable prognostic sign in women with HPV 16 positive cervical carcinoma. Several investigators have questioned the immunogenicity of the oncogenic HPV type 16 compared with other HPV types. It has recently been found that in HIV-infected patients, lymphoproliferative cellular immune responses (CMI) to HPV 16 peptides are not associated with CD4 counts, whereas responses to recall antigens and mitogens are associated with CD4 counts. CD4 + T cells may not be responsible for protective cellular immune responses to HPV. VLP serology and CMI responses may be the future intermediate surrogate biomarkers for HPV-associated anogenital neoplasia trials. Several new therapeutic vaccine strategies for management of HPV-induced neoplasia are reviewed. SUMMARY Most anogenital neoplasms occurring with increased frequency in patients with HIV/AIDS are associated with HPV infections. Current treatment strategies are not effective in clearing anogenital HPV infection and need improvement. Immunotherapy with novel vaccines will provide both prevention and therapy for these common malignancies.

Abstract
Cervical cancer is the most common malignancy amongst females in developing countries, mainly due to a lack of precursor screening. This absence of screening is the result of inherent disadvantages of the Pap smear: high cost, low sensitivity, the need for a laboratory with high human expertise and a complex screening program logistic system. The prerequisites for screening in a developing country include a screening method that is affordable, which can be effectively applied once in a lifetime at the age of 30-35 years, provide an immediate result and thereby allowing for on-site treatment of positive cases. None of the current screening methods comply with these prerequisites. More research is necessary into different combinations of tests, which improve sensitivity. On-site human papillomavirus (HPV) identification, alone or in combination with other tests, is promising. Another promising development is immunization against HPV infection, either as a preventative measure or for stimulating immunity in infected women.

Abstract
OBJECTIVE The objective of this study was to determine the prevalence of vulvar intraepithelial neoplasia (VIN) in adolescents presenting for cervical colposcopy in an adolescent gynecology office. MATERIALS AND METHODS We conducted a retrospective chart review from 1999 to 2002 of the concomitant diagnosis of cervical intraepithelial neoplasia and VIN in our private general pediatric and adolescent practice in patients younger than 22 years of age who underwent cervical colposcopy as well as evaluation of the vulva secondary to gross and microscopic visualized lesions. RESULTS Sixty-one patients underwent colposcopy for abnormal Pap smears; we found a 10% overall prevalence of vulvar intraepithelial neoplasia. Forty-four percent (n=27) underwent concomitant evaluation of the vulva; from these, 22% (n=6) fulfilled the characteristics of vulvar and cervical intraepithelial neoplasia. CONCLUSION In the presence of cervical cytology abnormalities, VIN may be more common than recognized and careful screening is definitely warranted.

Abstract
Survival rates for cancer of the uterine cervix have improved over the last 40 years largely because of the impact of screening measures such as the Pap smear. The ability to screen and treat women for preinvasive disease, cervical dysplasia, is the key factor leading to the reduction in the incidence of invasive cervical cancer. More recently, the ability to test women for the causative agent, the human papilloma virus, has emerged as a potential screening tool. New research has focused on new technologies for Pap smear screening such as thin layer technology, the appropriate intervals for screening, and the appropriate methods of incorporation of human papilloma virus testing into the screening protocols. Reviews of published studies evaluating the efficacy of new technologies suggest that there is still insufficient information to confirm improved outcome; however, results to date suggest that thin layer Pap smear technology may improve sensitivity in the detection of cervical dysplasia. Automated rescreening technologies in use may decrease the number of false-negative Pap smears and are an option for laboratories. Various professional groups and countries have differing recommendations on the interval for screening, primarily on the basis of cost-effectiveness. Some of the most important new information this year regarding cervical cancer screening includes the new Bethesda System for the reporting of Pap smears and the new guidelines for the management of the abnormal Pap smear by the American Society of Colposcopy and Cervical Pathology. These guidelines incorporate human papilloma virus testing based on a multicenter trial documenting its efficacy in the triage of women with atypical squamous cells on Pap smear. These recommendations are reviewed along with the current literature on cervical cancer screening.

Abstract
Persistent infection with human papillomavirus (HPV) type 16 has been implicated in the etiology of cervical cancer. The E2 protein is required early in viral infection and therefore may serve as a useful immune target for a vaccine aimed at prevention or therapy of premalignant lesions. Dendritic cells (DC) prepared from monocytes and pulsed with bacterially produced HPV 16 E2 C-terminus protein were used to stimulate autologous T cells over several rounds of stimulation. T cells were tested for gamma-interferon release by ELISPOT and for cytotoxic activity by (51)chromium release assays. To generate E2-expressing target cells for cytotoxicity assays, we constructed a recombinant vaccinia virus encoding HPV 16 E2, which was used to infect autologous Epstein-Barr virus-transformed lymphoblastoid cell lines (LCL). The results show that DC pulsed with E2 C-terminus protein induce gamma-interferon-releasing T cells as demonstrated by ELISPOT. Furthermore, we demonstrate E2-specific lysis of vaccinia-E2 infected autologous LCL by CD8+ cytotoxic T lymphocytes (CTL). E2-specific CTL did not lyse untreated autologous LCL or LCL infected with wild-type vaccinia and showed low levels of cytotoxicity against natural killer cell-sensitive K562 cells. In addition, T cells stimulated with DC in the absence of E2 failed to demonstrate lysis of vaccinia-E2-labeled targets. Phenotypically, CTL populations were CD3+/CD8+. These results will facilitate the study of naturally occurring T-cell responses to HPV E2 in patients with cervical intraepithelial neoplasia and the development of immunotherapeutic strategies designed to treat this and other HPV-associated diseases.

Abstract
Ovarian cancer is the leading cause of death from malignancies arising in the female genital tract. More women die from ovarian cancer than cervical and endometrial cancer combined. All clinicians should understand the concepts of ovarian cancer biology and management. Approximately 90% of all ovarian cancers are epithelial in origin, and such cancers are the focus points of this article.

Abstract
Human papillomavirus (HPV) infection of the lower genital tract is now considered the most important factor in the initiation of neoplasia. Human immunodeficiency virus (HIV) infection appears to alter the natural history of HPV-associated oncogenesis, but its impact on gynaecology has only recently been defined; the Centers for Disease Control (CDC) designated moderate and severe cervical dysplasia as a category B defining condition, and invasive cervical cancer as a category C defining condition of AIDS in 1993. Anal HPV infection and anal squamous intra-epithelial lesions have been found to be highly prevalent among HIV-positive homosexual men, and recent preliminary data suggest a relatively high prevalence among HIV-positive women as well. Moreover, HPV infection and associated lesions are also observed in body sites other than the anogenital area, particularly the skin and the oral cavity.

Abstract
OBJECTIVES The incidence of cervical dysplasia and carcinoma is known to be increased in HIV-infected women. In addition, there is a positive correlation between HIV viral load (VL), CD4+ count, and opportunistic infections, as well as the incidence of various malignancies. This study compares HIV VL and CD4+ count with the presence of cervical dysplasia, as well as with the degree of severity of dysplasia. METHODS A retrospective chart review of 350 HIV-infected women with polymerase chain reaction (PCR) quantitation of viral load was performed to identify 82 women with biopsy-proven cervical dysplasia and 25 women without any significant cervical pathology. The highest plasma VL within a year of the patients' cervical pathology and corresponding CD4+ count was selected and compared with cervical pathology. Univariate and multivariate statistical analysis using Student's t test and logistic regression analysis was used to analyze the significance of other risk factors such as age, race, smoking history, history of illicit drug use, and prior sexually transmitted disease as well as of viral load and CD4+ count. RESULTS Of 82 cases of cervical dysplasia, 33 (40.24%) were mild (CIN I), 47 (57.32%) were either moderate or severe (CIN II-III) dysplasia, and 2 demonstrated invasive squamous cell carcinoma (2.44%). A significant statistical difference was found when comparing either HIV plasma VL or CD4+ T-cell counts with the presence of cervical dysplasia on biopsy (P < 0.005). However, only CD4+ count was identified as an independent risk factor for the presence of cervical dysplasia after multivariate analysis. CONCLUSION In our population, there is a significant correlation between VL and CD4+ count and the presence of cervical dysplasia. However, VL does not appear to be an independent risk factor for cervical dysplasia in this population of HIV-infected women.

Abstract
UNLABELLED In the general population, nonadherence to the recommendation to have colposcopy in women with abnormal cytologic smears is estimated at 30% to 80%, but studies have failed to identify consistent risk factors for nonadherence. The purpose of this analysis is to assess adherence to colposcopy in a subset of participants in the Women's Interagency HIV Study (WIHS), an ongoing multisite longitudinal study of HIV infection in women in the United States and determine factors associated with nonadherence. Identification of such predictors would be useful in designing strategies to improve adherence in this group. METHODS Adherence to colposcopy was examined in a cohort of 462 women with, or at risk for, HIV infection with abnormal cervical cytology on entry into WIHS. Adherence was defined as having colposcopy done within 6 months of an abnormal cytology result. RESULTS Overall adherence to colposcopy was 65% (302 of 462). A multivariate logistic regression model revealed that the odds of adherence were significantly lower for the women who were HIV-infected (p = .011), current crack/cocaine users (p = .040), ever too ill to get medical care (p = .033), not recruited by WIHS study staff (p = .004), and less concerned about the care of their children (p = .037). Among HIV-seropositive women, low CD4 counts, high viral loads, and presence of AIDS-defining illness were not predictive of nonadherence. DISCUSSION Adherence to colposcopy among WIHS participants was at the upper limit of the reported range in the United States. Chemical dependency and domestic violence may negatively impact on colposcopy adherence whereas supportive study personnel, having health insurance, and concerns about raising one's children appear to be motivators for adherence to colposcopy in this study. HIV infection was a risk factor for nonadherence, but markers of advanced disease were not predictive of nonadherence.
