Abstract
Cervical cancer is the first cancer deemed amenable to elimination through prevention, and thus lessons from the epidemiology and prevention of this cancer type can provide information on strategies to manage other cancers. Infection with the human papillomavirus (HPV) causes virtually all cervical cancers, and an important proportion of oropharyngeal, anal and genital cancers. Whereas 20th century prevention efforts were dominated by cytology-based screening, the present and future of HPV-associated cancer prevention relies mostly on HPV vaccination and molecular screening tests. In this Review, we provide an overview of the epidemiology of HPV-associated cancers, their disease burden, how past and contemporary preventive interventions have shaped their incidence and mortality, and the potential for elimination. We particularly focus on the cofactors that could have the greatest effect on prevention efforts, such as parity and human immunodeficiency virus infection, as well as on social determinants of health. Given that the incidence of and mortality from HPV-associated cancers remain strongly associated with the socioeconomic status of individuals and the human development index of countries, elimination efforts are unlikely to succeed unless prevention efforts focus on health equity, with a commitment to both primary and secondary prevention.

Abstract
Gynecologic cancers, starting in the reproductive organs of females, include cancer of cervix, endometrium, ovary commonly and vagina and vulva rarely. The changes in the composition of microbiome in gut and vagina affect immune and metabolic signaling of the host cells resulting in chronic inflammation, angiogenesis, cellular proliferation, genome instability, epithelial barrier breach and metabolic dysregulation that may lead to the onset or aggravated progression of gynecologic cancers. While microbiome in gynecologic cancers is just at horizon, certain significant microbiome signature associations have been found. Cervical cancer is accompanied with high loads of human papillomavirus, Fusobacteria and Sneathia species; endometrial cancer is reported to have presence of Atopobium vaginae and Porphyromonas species and significantly elevated levels of Proteobacteria and Firmicutes phylum bacteria, with Chlamydia trachomatis, Lactobacillus and Mycobacterium reported in ovarian cancer. Balancing microbiome composition in gynecologic cancers has the potential to be used as a therapeutic target. For example, the Lactobacillus species may play an important role in blocking adhesions of incursive pathogens to vaginal epithelium by lowering the pH, producing bacteriocins and employing competitive exclusions. The optimum or personalized balance of the microbiota can be maintained using pre- and probiotics, and fecal microbiota transplantations loaded with specific bacteria. Current evidence strongly suggest that a healthy microbiome can train and trigger the body's immune response to attack various gynecologic cancers. Furthermore, microbiome modulations can potentially contribute to improvements in immuno-oncology therapies.

Molecular characterization of invasive and in situ squamous neoplasia of the vulva and implications for morphologic diagnosis and outcome. Mod Pathol 2021; 34:508-518. [PMID: 32792599 DOI: 10.1038/s41379-020-00651-3] [Citation(s) in RCA: 28] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2020] [Revised: 07/30/2020] [Accepted: 07/31/2020] [Indexed: 01/01/2023]
Abstract
Human papillomavirus (HPV)-independent vulvar squamous cell carcinoma (VSCC) is an aggressive clinical entity. Current diagnostic guidelines for premalignant lesions are ambiguous, and their molecular profile and progression events are still unclear. We selected 75 samples, from 40 patients, including 33 VSCC, 8 verrucous carcinomas (VC), 13 differentiated-type vulvar intraepithelial neoplasia (dVIN), 11 suspicious for dVIN (?dVIN), 6 differentiated exophytic vulvar intraepithelial lesions (DE-VIL), 2 vulvar acanthosis with altered differentiation (VAAD), and 2 usual-type vulvar intraepithelial neoplasia (uVIN/HSIL). Invasive and precursor lesions were matched in 29 cases. Clinical information, p16 immunohistochemistry, and mutation analysis were performed on all lesions. All dVIN, ?dVIN, DE-VIL, and VAAD were p16 negative, all uVIN/HSIL were p16 positive. In the HPV-independent group, mutations were identified in 6 genes: TP53 (n = 40), PIK3CA (n = 20), HRAS (n = 12), MET (n = 5), PTEN (n = 4), and BRAF (n = 1). TP53 mutations occurred in 73% (22/30) VSCC, 85% (11/13) dVIN, 70% (7/10) ?dVIN and no VC (0/8), DE-VIL (0/6) nor VAAD (0/2). Basal atypia was the only reliable feature of TP53 mutations. ?dVIN lesions that were non-acanthotic and atypical but obscured by inflammation, all harbored TP53 mutations. In lesions without TP53 mutations, PIK3CA (50% VC, 33% DE-VIL, 100% VAAD, 40% VSCC) and HRAS (63% VC, 33% DE-VIL, 0% VAAD, 20% VSCC) mutations were found. Mutational progression from in situ to invasive was seen (7/26, 27%) and usually involved TP53 (4/26, 15%). Cases with TP53 and PIK3CA co-mutations had the worse clinical outcomes (p < 0.001). We recommend testing for p53 in all HPV-independent lesions suspicious for dVIN, even in the presence of marked inflammation or non-acanthotic skin, particularly when close to a margin. VC, VAAD, and DE-VIL, were almost never mutated for TP53, but instead often harbored PIK3CA and HRAS mutations. In VSCC, combined TP53 and PIK3CA mutations may inform prognosis.

Abstract
Vulval squamous cell carcinoma (VSCC) can arise through two distinct pathways [human papillomavirus (HPV)-associated and HPV-independent], and these VSCC variants are recognised as different disease entities on the basis of different aetiologies, morphological features, molecular events during oncogenesis, precursor lesions, prognosis, and response to treatment. The precursor of HPV-associated VSCC, variously referred to as high-grade squamous intraepithelial lesion (HSIL) [vulvar intraepithelial neoplasia (VIN) 2/3] or usual-type VIN, is morphologically identical to the more common HSIL (cervical intraepithelial neoplasia 2/3) of the cervix. The precursor lesions of HPV-independent VSCC include differentiated VIN, differentiated exophytic vulvar intraepithelial lesion, and vulvar acanthosis with altered differentiation; these have been under-recognised by pathologists in the past, leading to delays in treatment. This review will discuss the recent advances in diagnostic surgical pathology of VSCC and its precursors, and how these diagnoses can impact on patient management.

Abstract
OBJECTIVE To investigate the incidence and survival of Vulvar Squamous Cell Carcinoma (VSCC) by etiology over a 27 year period. METHOD Retrospective case-note and pathology slide review of 390 consecutive VSCC, treated at a Centralized Cancer Centre covering half New Zealand's population, 1990-2016. Incidence was calculated in 5-6 year cohorts and correlated with precursor of the VSCC, age and stage. RESULTS Age-standardized incidence of all VSCC did not change significantly, however age standardized incidence of HPV-dependent VSCC increased significantly, from 0.55/100,000 (95% CI 0.38-0.72) in 1991-2000 to 0.83/100,000 (95% CI 0.68-0.97) in 2001-2016, with a significant decrease in the incidence of HPV-independent VSCC, from 0.76/100,000 (95% CI 0.58-0.95) to 0.54/100,000 (95%CI 0.43-0.65). HPV-dependent VSCC in women ≥50 years increased significantly from 0.75/100,000 (95% CI 0.45-1.17) to 1.43/100,000 (95% CI 1.14-1.77), with no significant change seen in younger women. HPV-independent VSCC in women ≥50 years has decreased significantly from 2.53/100,000 (95% CI 1.95-3.23) to 1.62/100,000 (95% CI 1.31-1.98) with no change in younger women. The proportion of HPV-dependent VSCC has increased from 25% to 50%. Age standardized death rate from VSCC has not changed significantly from 0.22/100,000 (95% CI 0.10-0.34) in 2001-5 to 0.27/100,000 (95% CI 0.15-0.40) in 2011-16. Five year survival for HPV-dependent VSCC was 93% and 68% for HPV-independent VSCC (p < .0001). CONCLUSIONS HPV-dependent VSCC incidence has increased significantly and now accounts for half of VSCC, with a significant rise in women over 50. HPV-dependent and independent VSCC have different prognoses and should be registered and investigated separately.

Abstract
Most human papillomavirus (HPV)-associated vulvar squamous cell carcinomas (VSCCs) originate from high-grade squamous intraepithelial lesions, also named usual type vulvar intraepithelial neoplasia. However, growing evidence suggests that morphologic studies have limitations in predicting HPV status in vulvar lesions. We aimed to evaluate adjacent intraepithelial lesions in a series of DNA HPV-positive VSCCs, focusing on unusual histologic patterns mimicking differentiated vulvar intraepithelial neoplasia (dVIN) or lichen sclerosus (LS). We identified 326 DNA HPV-positive VSCC with at least 1 cm of skin adjacent to the invasive tumor and analyzed HPV typing, HPV E6*I mRNA, and p16 immunohistochemistry in all cases. A careful histologic evaluation was conducted. A conclusive association with HPV was based on a positive p16 or HPV E6*I mRNA result or both in addition to the HPV DNA, whereas cases negative for both markers were classified as nonconclusively associated with HPV. One hundred twenty-one tumors (37.1%) had normal adjacent skin, 191 (58.6%) had only high-grade squamous intraepithelial lesions, also named usual type vulvar intraepithelial neoplasia, and unusual intraepithelial lesions were identified in 14 (4.3%) tumors. Seven cases showed dVIN-like features, 5 showed adjacent LS-like lesion, and in 2 cases dVIN-like and LS-like lesions were identified simultaneously. Six of them were conclusively associated with HPV (3 dVIN-like, 2 LS-like, 1 with combined dVIN/LS-like features). All 6 tumors were associated with HPV16 and were positive for both p16 and HPV mRNA, and p16 was also positive in the dVIN-like and LS-like lesions. In summary, a small subset of VSCCs conclusively associated with HPV may arise on intraepithelial lesions, mimicking precursors of HPV-independent VSCC.

Abstract
Background Metastatic vulval adenocarcinoma is a rare occurrence with only a few cases reported to date. They can arise from the breast, gastrointestinal system, or endometrium. Case presentation We present the case of a 55-year-old Black African woman who presented with vulval itching which progressed to warty lesions. Histology revealed a vulval adenocarcinoma which immunohistochemistry suggested was of gastrointestinal origin. Colonoscopy later confirmed an anorectal tumor as the primary site. Despite extensive chest metastases she looked surprisingly well and had no pulmonary symptoms. The major source of symptomatic distress was the itchy extensive warty lesions on her vulva. She has since had a vulvectomy which gave her significant symptomatic relief. Conclusions This case was interesting as vulval adenocarcinoma is a rare histological diagnosis found in less than 10% of vulval cancers. Primary vulval adenocarcinoma is rare with most of these cancers being secondary metastases from a distant site. Her symptoms were predominantly vulval with no chest symptoms even though she had extensive pulmonary metastases. She has been clinically well except for the itching suggesting an indolent course.

Abstract
OBJECTIVE Vulvar squamous cell carcinoma (VSCC) develops through 2 distinct molecular pathways, one involving high-risk human papillomavirus (HPV) infection and the other through early p53 suppressor gene mutation. We sought to evaluate the influence of p53 mutation, HPV status, and p16 expression on local recurrence and disease-specific mortality in early stage VSCC. MATERIALS AND METHODS We performed a retrospective chart review of all patients with stage I VSCC at the Maine Medical Center from 1998 to 2007 (n = 92). Tumor size, depth of invasion, lymphatic/vascular space invasion, and growth pattern were recorded. Paraffin-embedded tissue blocks were stained by immunohistochemistry for p16 and p53; high-risk HPV was detected by polymerase chain reaction assay. Margin distance was determined by a gynecologic pathologist. Survival analyses were conducted to examine predictors of VSCC recurrence and disease-specific mortality. RESULTS Age, depth of invasion, lymphatic/vascular space invasion, growth pattern, and margin status were not significant predictors of recurrence or disease-specific mortality. Tumor size of greater than 4.0 cm indicated a 4-fold increase in disease-specific mortality but did not significantly increase recurrence. p16-Positive patients were less likely to recur and had no VSCC-related deaths. Human papillomavirus-positive patients were less likely to recur and had no VSCC-related deaths. p53-positive patients were 3 times more likely to recur and nearly 7 times more likely to die from vulvar cancer. CONCLUSIONS Our findings suggest that HPV and the surrogate biomarker p16 indicate a less aggressive type of vulvar cancer. p53 positivity was associated with poor prognosis and significantly increased both recurrence and disease-specific mortality.

Abstract
Cervical carcinoma ranks among the most common tumors worldwide and is especially prevalent in the developing world. Strong evidence supports the role of human papillomavirus (HPV) infection in the genesis of these tumors. The authors examined 65 cervical neoplasias from a population of women at particularly high risk for the development of cervical cancer in Western China. HPV DNA analysis consisted of in-situ hybridization (n=65) and polymerase chain reaction (PCR) (n=58) for the detection of HPV types 6, 11, 16, 18, 31, 33, and 35. Both consensus and type-specific primers for HPV types 6, 16, and 18 were used in the PCR studies. Overall, HPV DNA was detected in 76.9% of cases. In-situ hybridization identified HPV DNA in 43.1% of patients. PCR with consensus primers detected HPV DNA in 22.4% of lesions, whereas type-specific primers for the HPV E6 gene demonstrated HPV DNA in 77.6% of cervical tumors. Type-specific PCR was more sensitive than LI consensus PCR and in-situ hybridization for detection of HPV DNA. Thirty-two (55.2%) cases that were negative by LI consensus PCR and 21 (32.3%) that were negative by in-situ hybridization were positive by type-specific PCR. Of the 50 cases positive for HPV DNA by one or more of these assays, 94% (n=47) were identified as HPV type 16; 4% (n=2) as HPV 31, 33, or 35; and 2% (n=I) as another, unidentified, HPV type. These data support the role of HPV in the pathogenesis of cervical carcinoma in high-risk women living in Western China. This study represents the first report of HPV analyses in Uygur women with cervical cancer.

Abstract
Recurrent disease occurs in 12-37% of patients with vulvar squamous cell carcinoma (VSCC). Decisions about treatment of recurrent VSCC mainly depend on the location of the recurrence and previous treatment, resulting in individualized and consensus-based approaches. Most recurrences (40-80%) occur within 2 years after initial treatment. Currently, wide local excision is the treatment of choice for local recurrences. Isolated local recurrence of VSCC has a good prognosis, with reported 5-year survival rates of up to 60%. Groin recurrences and distant recurrences are less common and have an extremely poor prognosis. For groin recurrences, surgery with or without (chemo) radiotherapy is a treatment option, depending on prior treatment. For distant recurrences, there are only palliative treatment options. In this review, we give an overview of the available literature and discuss epidemiology, risk factors, and prognostic factors for the different types of recurrent VSCC and we describe treatment options and clinical outcome.

Adjacent Lichen Sclerosis predicts local recurrence and second field tumour in women with vulvar squamous cell carcinoma. Gynecol Oncol 2016; 142:420-6.

Abstract
OBJECTIVE In this study, we investigated if the presence of histologically abnormal epithelium adjacent to the primary tumour influenced the frequency, timing, and topography of local vulvar recurrences (LVR) following treatment for squamous cell carcinoma of the vulva (VSCC). METHODS The study population comprised a cohort of 201 consecutive cases with incident VSCC. LVR were categorised as local relapses (LR) if they occurred <2cm from the tumour margins, and as second field tumours (SFT) when ≥2cm from these margins. Univariable and multivariable competing risk modelling was performed to identify the prognostic factors associated with local disease recurrence. RESULTS The characterization of the epithelium adjacent to the invasive component was possible for 199 (99.0%) patients. Of these, 171 (85.9%) were found to have intraepithelial abnormalities found adjacent to the surgical specimen. Multivariable analyses revealed that, following adjustment, Lichen Sclerosis (LS) was associated with an increase in the incidence of LVR, LR and SFT (SHRs: 3.4, 2.7 and 4.4, respectively). Although the incidence of LR and SFT in women with LS associated VSCC was similar, the peak incidence of SFT occurred more than two years before that of LR. CONCLUSIONS Women with VSCC arising in a field of LS may continue to have an increased risk of developing LR and SFT for many years after resection of their primary tumour. Our study suggests that these women should be followed up more regularly so that LVR can be detected earlier; unless a more robust surveillance programme or chemopreventative treatments become available.

Abstract
Objective This study aimed to examine the prognostic value of overexpressed p16INK4a in vulvar cancer. Although the tumor suppressor p16INK4a has been shown to be of prognostic value in a wide variety of cancers and precancerous lesions, its role in the vulvar cancer is still unclear. Methods All publications in English language on the association between p16INK4a and clinicopathological features of vulvar cancer were searched from Pubmed, Embase, and Web of Science, and those in Chinese language were identified manually and online from the China National Knowledge Infrastructure. Strict inclusion and exclusion criteria were followed. Odds ratios(ORs) or risk ratios(RRs) with 95% confidence intervals(CIs) were pooled to assess the strength of association. Publication bias was estimated using funnel plots and the Egger’s regression test. Results A total of 17 studies with 2309 patients were included. The p16INK4a overexpression was found to correlate significantly with the lower International Federation of Gynecology and Obstetrics stage(I+II vs III+IV; OR = 0.60,95%CI:0.41–0.86,P = 0.006),negative lymph node metastasis(negative vs positive; OR = 0.61,95%CI:0.39–0.95,P = 0.029),patient’s age<55(OR = 0.54,95%CI:0.31–0.96,P = 0.034),human papillomavirus–positive status(OR = 0.01,95%CI:0.00–0.11,P<0.001),and higher overall survival(RR = 0.53,95%CI = 0.35–0.80,P = 0.003). Conclusion The p16INK4a might be associated with a higher survival and indicates better prognosis of vulvar cancer.

Abstract
We evaluated p16INK4A as a reliable option to detect human papilloma virus (HPV) DNA in penile tumor specimens. Formalin-fixed paraffin embedded samples of 26 patients with penile cancer and another 18 cases with non-tumorigenic lesions were stained by three different widely used commercially available chromogenic in-situ hybridization assays high-risk HPV CISH Y1443 (Genpoint, DAKO), pan HPV CISH Y1404 (Genpoint, DAKO), INFORM HPV III (Ventana, Tucson, Arizona) and p16INK4A immunohistochemistry, then compared to the known gold standard polymerase chain reaction detecting HPV 16, 18, 31, and 33. Immunoreactivity for p16INK4A was evaluated by using a 4-tiered (0, 1, 2, and 3) pattern based system. 19 cases were positive for p16INK4A, 13 of which showed a continuous transepithelial staining (pattern 3). Pan HPV ISH showed positivity in 9 cases, high-risk HPV ISH in 7 cases and INFORM HPVIII ISH in 7 cases. p16INK4A IHC pattern 3 versus pattern 0, 1 and 2 exhibited a specificity and positive predictive value of 100 percent, with a sensitivity and negative predictive value of 72 and 62 percent, respectively, which was much better than all HPV in-situ hybridization methods referred to polymerase chain reaction. p16INK4A seems to be a superior marker for the detection of HPV-associated penile squamous cell carcinoma compared to CISH tests, but is not recommend for the detection of non-tumorigenic lesions, where PCR should be used for the initial assessment.

Abstract
INTRODUCTION Vulvar cancer is a rare condition representing about 4% of all female genital tract tumors. In contrast to the established relationship of virtually all cervical cancer cases with the human papillomavirus (HPV) infection, the reported HPV positivity in vulvar carcinoma ranges widely. METHODS Using the Linear Array HPV Genotyping Test, we investigated the HPV incidence in a group of 46 Polish patients with vulvar squamous cell carcinoma (age range, 37-93 years; median age, 70.2 years) in clinical stages T1-2, N0-2, and M0. RESULTS The presence of HPV DNA was confirmed in 7 of 46 (15%) primary tumor samples. HPV 16 was found in 5 tumors (71%). HPVs 6 and 58 were detected in the remaining 2 cases of virus-associated tumors. CONCLUSIONS We conclude that a fraction of cancers of vulva associated with HPV is insignificant, given the HPV prevalence of 8.6% in the Polish population aged 55 to 59 years (the oldest cohort of Polish women studied to date).

Abstract
OBJECTIVE The objective of the study was to identify prognostic and environmental factors associated with vulvar carcinoma in young women. STUDY DESIGN This study was a review of patients younger than 45 years who were diagnosed with vulvar squamous cell carcinoma between 1994 and 2006. RESULTS Fifty-six patients were identified. Median age was 38 years and median follow-up was 25.3 months. Fifty-eight percent of patients presented with stage I disease; 77% smoked tobacco. Of patients with advanced disease, 53.3% were smokers, 40% had human papillomavirus (HPV) exposure, 46.7% had a history of vulvar intraepithelial neoplasia (VIN), and 6.7% were immunocompromised. Symptoms were present for more than 12 months in 47%, but symptom duration did not correlate with stage (P = .42) or positive lymph nodes (P = .28). Disease recurred in 10.7% and 5.4% died of disease. CONCLUSION Young women with vulvar cancer tend to have early-stage disease, smoke, have a history of HPV, and have VIN. Many of the factors that place these patients at continuous risk are modifiable.

Abstract
Strong epidemiologic and molecular data now support the conclusion that human papillomavirus (HPV) infection is responsible for a distinct form of head and neck squamous cell carcinoma (HNSCC), independent from the traditional risk factors of tobacco and alcohol use. Patients with HPV-positive HNSCC have a different clinical presentation and better clinical outcomes than those with HPV-negative HNSCC. A diagnosis of HPV-positive HNSCC is associated not only with therapeutic relevance, but also has important implications for future prevention and screening strategies.

Abstract
Many studies have established a critical role for human papillomavirus (HPV) in the development of anogenital squamous neoplasia. In this report, we show the distribution of 37 high- and low-risk HPV types in 116 cases of invasive squamous vulvar carcinoma. Sections from paraffin-embedded tissue blocks were dissected as necessary to select areas of invasive carcinoma. Clinical and pathologic variables were analyzed using t-tests, univariate odds ratios and logistic regression analysis. Seventy percent of cases were HPV-positive, with an average patient age of 65 years (n=81). HPV-negative cases (n=35) had a higher average age (70 years), but these populations were not statistically different (t=1.65, P=0.10). HPV16 was most common (n=65). Other HPV types were less frequent (HPV33, n=12; HPV45, n=4; HPV52 and 6, each n=3; HPV18, 53 and 62, each n=2). Additional HPV types were identified only once. Multiple infections typically included HPV16 (12/14 cases). Tumors showing low-risk HPV (11 cases) and low-risk HPV only (three cases) were uncommon. Regional node metastasis was documented in 29 of 116 tumors, and 8/9 HPV-positive nodes contained HPV types identical to the primary tumor. Of tumor types, warty carcinoma was most strongly associated with high-risk HPV (odds ratio 4.34, 95% confidence interval 1.32-18.45), particularly high-risk HPVs other than type 16 (odds ratio 9.04, 95% confidence interval 1.60-54.00). Tumors associated with any HPV type (odds ratio 0.40, 95% confidence interval 0.14-1.17), any high-risk type (odds ratio 0.36, 95% confidence interval 0.12-1.08), or type 16 alone (odds ratio 0.34, 95% confidence interval 0.11-1.12) were less likely to metastasize than HPV-negative tumors. Correcting for possible confounding variables, such as patient age and tumor histology, linear logistic regression analysis confirmed this association (high-risk HPV odds ratio 0.28, 95% confidence interval 0.09-0.89).

Abstract
Two independent pathways of vulvar carcinogenesis have currently been identified, one related to infection with mucosal human papillomaviruses (HPVs) and a second related to chronic inflammatory or autoimmune processes. The goal of the study was to examine a possible role of cutaneous HPVs from the beta genus in vulvar carcinogenesis and to evaluate the distribution of intratypic variants of HPV 16 in HPV 16-positive vulvar cancer. Consecutive cases of vulvar carcinoma were retrieved from the files and included the following histologic subtypes: keratinizing (n=21), basaloid (n=7), warty (n=1), mixed basaloid-warty (n=4), verrucous (n=4), keratoacanthoma (n=1), basal cell carcinoma (n=1). All tumors were microdissected and tested for 25 beta HPV types and 25 mucosal HPV types. Cases identified as positive for HPV 16 were further tested for intratypic variants. All cases were immunostained for p16INK4a. Beta HPVs were not detected in any of the tumor cases. Mucosal HPVs were detected in all but one basaloid/warty carcinomas; of these, nine cases (82%) were positive for HPV 16, including five European subtypes, one African subtype, one North American subtype and two indeterminate subtypes. Two of four verrucous carcinomas were positive for HPV 6. Mucosal HPVs were not detected in keratinizing carcinomas, keratoacanthoma and basal cell carcinoma. All cases of basaloid/warty carcinomas, but none of the remaining tumors, overexpressed p16INK4a protein. Our data do not support a role of beta HPVs in the pathogenesis of vulvar carcinoma. The study reaffirms the role of mucosal HPVs, in particular that of HPV 16, in the pathogenesis of basaloid and warty tumor subtypes. The HPV 16 intratypic variation showed correlation with patients' ethnic background. P16INK4a immunostaining seems to be a sensitive and specific marker of vulvar carcinomas positive for oncogenic mucosal HPVs.

Abstract
The objective of this review is to summarize the published data about squamous carcinoma of the vulva and to identify promising areas for future investigation. Rather than the routine use of complete radical vulvectomy, a radical wide excision of the vulvar lesion to achieve at least a 1-cm gross margin appears sufficient to treat the primary lesion. A surgical assessment of the groin is required for all patients who have invasion greater than 1 mm. Ipsilateral groin node dissection can be performed through a separate incision. All the nodal tissue medial to the vessels and above the fascia should be removed. Sentinel node evaluation may be a significant step forward, but the false-negative rate is not well enough defined to consider this a standard. Patients with positive inguinal nodes at groin dissection should receive radiation therapy to the ipsilateral groin and hemipelvis. For those patients who have unresectable primary disease or if nodes are palpably suspicious, fixed, and/or ulcerated preoperatively, chemoradiation is the preferred option. Exenterative procedures may rarely be required. Chemotherapy for recurrent or metastatic disease has not been proven to be of value. Although survival rates are high for those with negative nodes, the morbidity associated with standard radical techniques has prompted innovation. Adequately powered trials aimed at further reducing morbidity without compromising survival are underway.

Abstract
Long considered as ectopic breast tissue, anogenital mammary-like glands (MLGs) have recently been suggested to represent distinctive structures located in the anogenital area. We studied 16 neoplasms of anogenital MLG for human papillomavirus (HPV) DNA using INNO-line probe assay (LiPA) HPV Genotyping kit, GP5+/6+, CP(SGB), and FAP 6085-6319 primer sets. The lesions included 3 fibroadenomas, 2 adenosis tumors, 1 invasive ductal carcinoma, 1 tubulolobular carcinoma, 2 hidradenoma papilliferum with prominent cystic change rendering a cystadenoma appearance and oxyphilic metaplasia, and 7 cases of extramammary Paget disease. All 3 fibroadenomas, both adenosis tumors, both hidradenoma papilliferum, and the tubulolobular carcinoma proved negative for HPV DNA. HPV-31 was detected by LiPA in the case of invasive ductal carcinoma. In 2 of the 7 patients with extramammary Paget disease, there was HPV DNA present in the lesional tissue, typed as HPV-6 (LiPA) and a type which was closely related to HPV-21 and HPV-24 (FAP 6085-6319), whereas the remaining 5 cases tested negative. These results coupled with those obtained from literature review suggest that HPV plays no causative role in lesions of anogenital MLG.

Abstract
OBJECTIVE Human papillomavirus (HPV) is a necessary cause for cervical cancer, and it has been associated with vulvar and vaginal cancer and vulvar (VIN) and vaginal (VaIN) and anal (AIN) intraepithelial neoplasia. We assessed the prevalence of HPV (and the types) to estimate the possible effect of a HPV vaccine on lower genital tract disease prevention. METHODS Two hundred fifty-eight samples of VIN, VaIN, AIN, and vulvar cancer from 241 women were included in the study. The diagnosis of surgical samples was made using published histomorphologic criteria. The DNA was extracted for HPV detection and typed using polymerase chain reaction and sequencing. RESULTS The analyses were performed on 210 intraepithelial neoplasia samples (VIN2/3, VaIN2/3, AIN2/3) and 48 vulvar carcinoma samples. Human papillomavirus DNA was detected in 92%, 91%, 89%, and 60% of the VIN, VaIN, AIN, and vulvar carcinoma samples, respectively. High-risk HPV types 16 or 18 were detected in 76%, 64%, 81%, and 42% of the VIN2/3, VaIN2/3, AIN, and vulvar carcinoma samples. Women with HPV-positive samples were younger than those with HPV-negative samples (46 years compared with 55 years and 51 years compared with 61 years, for the VIN2/3 and vulvar carcinoma samples, respectively). Human papillomavirus-positive vulvar carcinoma was more frequent in women aged younger than 56 years (77%), than in those aged 56 years or older (41%). CONCLUSION Based on the data obtained in this study, widely-implemented prophylactic HPV vaccination could make an important contribution to the reduction of the risk for cervical cancer and could also prevent about half the vulvar carcinomas in younger women and about two thirds of the intraepithelial lesions in the lower genital tract.

Abstract
This study was undertaken to examine the expression of p16 and p53 in vulvar intraepithelial neoplasia (VIN) and squamous cell carcinoma (SCC) of the vulva. We also analyzed the relationship between p16 and p53 immunoexpression in women younger vs. older than 55 years of age. Seventyseven histologic samples of vulvar tissue, treated surgically between June 2000 and November 2004 at the Complexo Hospitalar Santa Casa (Porto Alegre, Brazil), were investigated. We analyzed 28 cases of VIN, 37 cases of SCC and 12 normal vulvar tissues. The percentage of immunohistochemical positivity for p16 had the following distribution across the groups: VIN: 21.4% (6/28), cancer: 24.3% (9/37) and control: absent (p=0.202). p53 expression showed the following percentages: VIN: 60.7% (17/28), cancer: 18.9% (7/37) and control: 8.3% (1/12) (p=0.01). p16 expression in the cancer group (mean age: 63.4 years) was positive in 6 and 3 cases of women younger or older than 55 years, respectively (54.5% vs. 11.5%, p=0.01). p53 expression was not detected in young females with cancer, while it was expressed in 7/26 (26.9%) cases of the group of females older than 55 years of age (p=0.08). Our results suggest an increase in the immunohistochemical expression of p16 protein in young women with squamous cell carcinoma of the vulva, and a possible association with a low expression of p53.

Abstract
The present study addressed the impact of human papillomavirus (HPV), p14, and the product of the retinoblastoma gene (pRb) in vulvar carcinoma in relation to other clinicopathologic variables and prognosis. We immunohistochemically studied 217 primary tumors from patients with vulvar carcinoma for the expression of pRb and p14. By the use of in situ hybridization, the primary tumors and 7 lymph node metastases were studied for the presence of HPV-16, HPV-18, HPV-31, and HPV-33 DNA. HPV-infected cases significantly correlated with high expression of p14 (P < .01) and p16 (P < .01). In HPV- cases with high expression of p53, no p14 expression predicted the poorest disease-specific survival (P < .01). For the first time, we have shown that p14 expression indicates longer disease-specific survival in patients with vulvar carcinoma. In patients with HPV- tumors expressing high levels of p53, low p14 indicated the poorest 5-year disease-specific survival.

Abstract
OBJECTIVE To characterize the incidence of vulvar carcinoma in situ and vulvar cancer over time. METHODS We used the Surveillance Epidemiology and End Results database to assess trends in the incidence of vulvar cancer over a 28-year period (1973 through 2000) and determined whether there had been a change in incidence over time. Information collected included patient characteristics, primary tumor site, tumor grade, and follow-up for vital status. We calculated the incidence rates by decade of age, used chi(2) tests to compare demographic characteristics, and tested for trends in incidence over time. RESULTS A total of 13,176 in situ and invasive vulvar carcinomas were identified; 57% of the women were diagnosed with in situ, 44% with invasive disease. Vulvar carcinoma in situ increased 411% from 1973 to 2000. Invasive vulvar cancer increased 20% during the same period. The incidence rates for in situ and invasive vulvar carcinomas are distributed differently across the age groups. In situ carcinoma incidence increases until the age of 40-49 years and then decreases, whereas invasive vulvar cancer risk increases as a woman ages, increasing more quickly after 50 years of age. CONCLUSION The incidence of in situ vulvar carcinoma is increasing. The incidence of invasive vulvar cancer is also increasing but at a much lower rate.

Abstract
Two separate pathways leading to vulvar carcinoma have been suggested. First, a human papillomavirus (HPV)-dependent pathway, in which premalignant stages of vulvar cancer are the classic vulvar intraepithelial neoplasia (VIN) lesions. Second, an HPV-independent pathway, associated with differentiated VIN III lesions and/or lichen sclerosus. To obtain insight into the mechanisms underlying these pathways, we determined the relationship between HPV DNA and the expression of p14(ARF) and p16(INK4A) in non- and (pre)malignant vulvar lesions. Seventy-three archival samples of non- and (pre)neoplastic vulvar lesions were selected and tested for hr-HPV DNA using a broad-spectrum HPV detection/genotyping assay (SPF(10)-LiPA) and the expression of p14(ARF) and p16(INK4A). The prevalence of HPV increased with the severity of the classic VIN lesions; in VIN I no hr-HPV was detected, in VIN II 43%, and in VIN III 71% of the samples were hr-HPV-positive. Roughly the same was true for the expression of p14(ARF) and p16(INK4A). The simultaneous expression of p14(ARF) and p16(INK4A) was highly associated with the presence of hr-HPV DNA. Hr-HPV was detected in only a single case of the differentiated VIN III lesions, whereas no expression of p14(ARF) was found and 16(INK4A) was present in only two cases. All 16 samples of vulvar cancer were hr-HPV DNA- negative, although in respectively 63% and 25%, p14(ARF) and p16(INK4A) was expressed. No relation was found between hr-HPV and the expression of p14(ARF) and p16(INK4A) in the 20 nonneoplastic vulvar lesions. Our results provide further evidence that vulvar squamous cell carcinoma is a multifactorial disease that develops from two different pathways. First, an HPV-dependent pathway with a remarkable resemblance to CIN lesions and cervical carcinoma and second, an HPV-independent pathway in which differentiated VIN III lesions that are hr-HPV-negative may be precursors.

Abstract
Reported here are 18 cases of hidradenoma papilliferum with oxyphilic metaplasia. All patients were women ranging in age from 29 to 74 years. Each presented clinically with a small, solitary tumor in the anogenital region. Microscopically, in addition to classic histopathological features, in every case there was oxyphilic metaplasia of the constituent epithelial cells. This finding could be likened to apocrine metaplasia, a term used in breast pathology. Other histopathological findings observed in this series, analogous to benign breast disease, included sclerosing adenosis-like changes, atypical apocrine adenosis-like changes, changes corresponding to usual ductal epithelial hyperplasia, epitheliomatosis with a streaming growth pattern, lamprocyte-like changes, clear cell change of the myoepithelium, foamy histiocyte reaction, and stromal fibrosis. Immunohistochemistry inferred that in the majority of cases oxyphilic metaplasia resulted from more lysosomes, whereas numerous mitochondria were detected in only 3 cases. Using 2 different PCR methods we identified HPV in 4 of 15 cases of hidradenoma with oxyphilic metaplasia. In addition, HPV was detected in 3 of 16 conventional papillary hidradenomas used as a control group. The following HPV types were identified: 16, 31, 33, 53, and 56. The last type was found in 5 cases. More than one HPV type from a single lesion was seen in 5 cases. Our observations are consistent with previous publications noting similarities between tumors of the breast and sweat glands. Oxyphilic metaplasia, areas with solid growth, and changes simulating atypical apocrine adenosis are rare and poorly recognized in hidradenoma papilliferum and may cause diagnostic difficulties; in our cases several submitting pathologists suspected malignancy. A causal role for HPV in hidradenoma papilliferum cannot be confirmed from our results, as the detection rate is too low. The exact role of the HPV in etiology and pathogenesis of this neoplasm has yet to be determined.

Abstract
OBJECTIVE Aberrant expression of the cell cycle kinase inhibitors p16, p21, and p27 has been associated with poor prognosis in a variety of human malignancies. Little is known, however, about their clinical impact in vulvar carcinoma patients. Thus, we analyzed a larger series of vulvar squamous cell carcinomas and compared the results with clinical outcome. METHODS A total of 224 vulvar squamous cell carcinomas were immunohistochemically investigated for expression of p16, p21, and p27 using the biotin-streptavidin-peroxidase method and the OptiMax Plus automated cell staining system. RESULTS High p16 (> or =5%) positive nuclear immunostaining was found in 69 (31%) cases, high p21 (any staining) protein levels was detected in 95 (42%) cases, and low p27 (< or =50% positive nuclei) staining was seen in 170 (76%) cases. High expression of p16 was related to lower patient age and low expression of p53. High expression of p16 indicated a better prognosis in the multivariate analysis (RR = 0.5, 95% CI = 0.2-1.0) and less risk of developing lymph node metastasis (OR = 0.3, 95% CI = 0.2-0.7). High level of p21 was significantly associated with shorter survival in patients staged FIGO I and II (RR = 3.4, 95% CI = 1.3-9.3). We found no significant correlation between the expression of p27 and any of the clinicopathological variables. CONCLUSIONS Our study indicates a prognostic relevance for p16 and p21 immunoreactivity. Low level of p16 protein and high level of p21 protein were associated with a shorter disease-related survival. We did not find p27 protein expression to be useful as a prognostic indicator in vulvar carcinoma patients.

Abstract
OBJECTIVE AND METHODS Ten vulvar squamous cell carcinoma cell lines established at the University of Michigan (UM-SCV-1A, -1B, -2, -3, -4, -6, -7) and at the University of Turku (UT-SCV-1, -2, -3) were characterized by G-banding karyotyping, comparative genomic hybridization (CGH), and deoxyribonucleic acid (DNA) flow cytometry. RESULTS All cell lines had hyperdiploid DNA content as measured by flow cytometry. The DNA index (DI) remained relatively stable through different passages in 9 of 10 cases. DIs of UM-SCV-3 and UT-SCV-2 were near-diploid, as were the corresponding karyotypes. The 10 SCVs showed remarkable genetic similarities with respect to consistent chromosome rearrangements. Loss of 3p, noted in 8/10 SCVs, was narrowed to the smallest common region at 3p11-3p13. Loss of 8pter-p11 was observed in 10/10 cell lines. Loss of 11qter-q23 was present in UM-SCV-1 and -2, and in all four recently karyotyped SCVs. Other consistent losses include Xpter-p11 in 6/10, and 18qter-q11 in 7/10 cell lines. Common gains included gain of 8q in 8/10 and 3q in 6/10. Consistent copy number imbalances were confirmed by CGH; concerning loss of 3p, in 63%, to loss of 8p in 70%, to gain of 3q in 83%, and to gain of 8q in 75% of the cell lines. CONCLUSIONS CGH and karyotyping showed concordance in defining copy number imbalances, thus supporting the accuracy of CGH to detect chromosome imbalances in tumors that cannot be karyotyped.

Abstract
OBJECTIVE The present study investigates the influence of lymph node pathological features and HPV DNA status on the prognosis of vulvar invasive tumors. METHODS This study includes 184 consecutive cases of primary invasive squamous cell carcinoma of the vulva treated by radical surgery from 1975 to 1992, in São Paulo, Brazil. Clinical follow-up data was collected from patient files and hematoxilin-eosin sections were reviewed. HPV detection and typing was done by polymerase chain reaction (PCR), using specific and generic primers, followed by dot blot hybridization (DBH) with type-specific oligonucleotide probes for 19 HPV types. Age-adjusted Kaplan-Meier survival curves and Cox proportional hazards models were used to analyze the cancer risk associations for all DNA and pathology-related variables. RESULTS Among 161 cases tested by PCR, 38 (23.6%) were positive for high-risk HPV types. Regional lymph nodes of 43 cases, including all those of HPV-positive tumors and a sample of the ones removed from patients with HPV negative tumors, were evaluated by the same method. HPV DNA was found in the lymph nodes of 10 cases. In every case, at least one lymph node was metastatic and the HPV detected in the lymph nodes were of the same type as those found in the primary tumor in all cases. Multivariate analysis including age, race, pattern of invasion, tumor thickness, inflammatory reaction, surgical margins, number of node metastases, presence of extracapsular growth, depth of invasion, and presence of high-risk HPV DNA was performed. Following automated selections of this model, node variables important for prognosis that remained were number of node metastases and presence of extracapsular growth. CONCLUSIONS Patients with four or more node metastases associated with extracapsular spread were 5.6 (95%CI: 2.3-13.1) times more likely to die from cancer and 10.0 (95%CI: 4.0-24.9) times more likely to have a recurrence than patients without metastases. The HPV status in the tumor was not important as a prognostic factor.

Abstract
INTRODUCTION Bowenoid papulosis is a characteristic lesion of the ano-genital region and represents a form of squamous cell carcinoma in situ, very often associated to the oncogenic high-risk human papilloma virus (HPV) types 16, 18, 31 and 33. Therapies applied so far, in general, show high rates of relapse, and patients complain of pruritus and pain. Imiquimod cream is a topical immune response modifier with indirect antiviral and antitumor effects through the stimulation of local cytokine production and cell-mediated immune response. CASE REPORT In the present paper we report on the topical application of imiquimod cream in a woman with a high-risk HPV-associated vulvar intraepithelial neoplasia grade III (VIN III) of the vulva. DISCUSSION In addition a review of the literature is given.

Abstract
OBJECTIVES To review the incidence, etiology, diagnosis, treatment, and nursing implications of the uncommon gynecologic malignancies of vulvar carcinoma, vaginal carcinoma, sex cord-stromal tumors of the ovary, and gestational trophoblastic tumors. DATA SOURCES Research studies, review articles, medical and nursing textbooks. CONCLUSIONS Vulvar and vaginal cancers, sex cord-stromal tumors of the ovary, and gestational trophoblastic tumors are rare malignancies constituting less than 5% of all malignant diagnoses. If detected early these malignancies have a high possibility of cure. IMPLICATIONS FOR NURSING PRACTICE Nurses play an important role in the education of women and patients to the signs and symptoms of gynecologic malignancies, the disease process, treatment options, follow-up care, and resources available to these women.

Abstract
The imaging evaluation of female lower genital tract cancers has undergone dramatic changes in the last two decades. Technical improvements and increased availability of cross-sectional modalities (US, CT, MR) have increased their use to such an extent that they have largely replaced more conventional imaging techniques. US is of limited value in the staging of vaginal and vulvar malignancies. CT is most useful for staging more advanced disease of the vagina and vulva. It is widely available and provides quick imaging time. CT is used in the detection and biopsy of suspected lymph nodes and metastases. MRI provides the best soft tissue contrast and is the most useful imaging modality available to evaluate carcinomas of the vagina and vulva. Future advancements in the imaging evaluation of vaginal and vulvar cancers will likely focus on functional imaging.

Abstract
OBJECTIVES Invasive squamous cell carcinoma (ISCC) of the vulva occurs most often in older women and the clinical, pathological, and immunohistochemical features of vulvar ISCC in young women are poorly characterized. The aim of this study was to examine clinical and pathological features of ISCC presenting in women younger than 40 years of age. METHODS Patients younger than 40 years of age who presented with vulvar ISCC were identified in the population-based tumor registry of the British Columbia Cancer Agency (BCCA) for the period 1970-1998. Clinical data and follow-up were obtained. The pathologic material was reviewed and morphologic features assessed. Immunohistochemical staining for MIB-1 and p53 proteins was done and the presence of human papillomavirus (HPV) DNA was assessed by microdissection/PCR. RESULTS Twenty-one cases, accounting for 5% of all cases of vulvar ISCC encountered at BCCA during this period, were identified, with patient's ages ranging from 17 to 39 years (mean 33). The number of cases of vulvar ISCC in young women, as a percentage of all cases of vulvar ISCC, increased significantly over the study period. Lichen sclerosus was seen in 3 cases. Vulvar intraepithelial neoplasia (VIN) was present in 20 of 21 cases and was multifocal in 4 of them. VIN was subclassified as warty in 7 cases, mixed warty and basaloid in 6, basaloid in 4, and differentiated in 3. There was MIB-1 immunostaining throughout the full thickness of warty and basaloid VIN. Only basal cells stained for MIB-1 in differentiated VIN. Increased p53 expression was present in only 2 cases; both were differentiated-type VIN. HPV DNA was detected in 17 of 20 cases. The tumors were staged as follows: stage IA, 3 cases; stage IB, 13 cases; stage II, 3 cases; stage III, 2 cases. Depth of invasion ranged from <1 to 8.5 mm. The definitive surgical procedure was vulvectomy with lymph node dissection in 14 cases, wide local excision in 6, and excisional biopsy in 1. Clinical follow-up of 1 to 28 years (median, 5 years) showed that 5 patients had local recurrence and 2 died of disease. Of the 21 patients in this study, 1 had concurrent HIV infection and 1 patient with Crohn's disease was treated with corticosteroids; the remaining patients had no clinical evidence of depressed immune function. CONCLUSIONS The incidence of vulvar ISCC in young women has increased over time; this increase cannot be accounted for by ISCC in immunocompromised patients. The overall disease outcome was excellent, with 2 of 21 patients dead of disease. Most tumors were associated with HPV, but cases of ISCC in the absence of HPV, and associated with differentiated VIN, were encountered. p53 staining of the basal layer can aid in recognition of differentiated VIN while MIB-1 staining within the upper layers of the squamous epithelium is consistently present in warty and basaloid VIN, but not in differentiated VIN.

Abstract
To clarify the role of human papillomavirus (HPV) in penile cancer we evaluated the prevalence of HPV DNA in different histological subtypes of penile carcinoma, dysplasia, and condyloma using a novel, sensitive SPF10 HPV polymerase chain reaction assay and a novel genotyping line probe assay, allowing simultaneous identification of 25 different HPV types. Formalin-fixed, paraffin-embedded tissue samples were collected from the United States and Paraguay. HPV DNA was detected in 42% cases of penile carcinoma, 90% cases of dysplasia, and 100% cases of condyloma. There were significant differences in HPV prevalence in different histological cancer subtypes. Although keratinizing squamous cell carcinoma and verrucous carcinoma were positive for HPV DNA in only 34.9 and 33.3% of cases, respectively, HPV DNA was detected in 80% of basaloid and 100% of warty tumor subtypes. There was no significant difference in HPV prevalence between cases from Paraguay and the United States. In conclusion, the overall prevalence of HPV DNA in penile carcinoma (42%) is lower than that in cervical carcinoma (approximately 100%) and similar to vulvar carcinoma (approximately 50%). In addition, specific histological subtypes of penile cancer--basaloid and warty--are consistently associated with HPV, however, only a subset of keratinizing and verrucous penile carcinomas is positive for HPV DNA, and thus these two tumor groups seem to develop along different pathogenetic pathways.

Abstract
Abnormalities in the cell cycle are associated with tumorigenesis but have not yet been identified in squamous cell carcinoma (SCC) of the vulva or in adjacent vulvar lesions. The purpose of this study was to identify cell cycle protein expression (cyclin D1 and retinoblastoma protein [pRb]) in vulvar SCC and in adjacent potentially premalignant lesions: lichen sclerosis (LS), squamous cell hyperplasia (SH), and vulvar intraepithelial neoplasia (VIN). Using immunohistochemical techniques, 57 SCCs were analyzed with 19 adjacent areas showing LS, 13 showing SH, 11 VIN, and six normal epithelium. Fifty-one percent of SCCs showed abnormal cyclin D1 expression and 37% showed abnormal pRb. Abnormal cyclin D1 expression in the adjacent areas was as follows: 53% in LS, 31% in SH, 18% in VIN, and 0% in normal. Abnormal pRb expression was as follows: 42% in LS, 62% in SH, 46% in VIN, and 33% in normal. Only 10 lesions showed abnormal expression of both proteins. Abnormal expression of cyclin D1 in SCC was statistically significant compared with adjacent normal epithelium. In SCC lesions, abnormal cyclin D1 expression was associated with greater depth of invasion. Abnormal pRb in SCC was associated with poor tumor grade. Cyclin D1 and pRb are separately involved in the progression of vulvar cancer, and changes in the expression of these proteins may represent an early stage of malignant transformation in vulvar disease.

Abstract
To determine if carcinogenic events in vulvar skin precede the onset of morphologic atypia, the authors investigated for derangements in DNA content, cell proliferation, and cell death in vulvar carcinomas and surrounding skin in 140 samples of tumor and surrounding skin collected from 35 consecutive vulvectomy specimen for squamous cell carcinoma (SCC) or vulvar intraepithelial neoplasia (VIN) 3. Vulvar non-cancer excisions were used as controls. Investigations consisted of histologic classification and measurement of 9 variables--epidermal thickness (acanthosis and rete ridge length), immunolabeling index (LI) for 3 proteins (p53 protein, Ki-67, and mdm-2), pattern of p53 expression (dispersed vs. compact), DNA content index, and presence of aneuploidy by image analysis and apoptotic rate by Apotag labeling. Significant positive correlations were found for all nine variables studied versus increasing histologic severity in two proposed histologic stepwise models of vulvar carcinogenesis (lichen sclerosus (LS) and VIN 3 undifferentiated associated SCC groups). High p53 LI (>25) and the compact pattern of p53 expression (suspected oncoprotein) significantly correlated with LS and its associated vulvar samples compared with samples not associated with LS (P < or = 0.001). Furthermore, p53 LI, mdm-2 LI, and pattern of p53 expression were concordant between patient matched samples of LS and SCC. In addition, mdm-2 LI significantly correlated with dispersed pattern p53 LI suggesting a response to wild-type p53 protein accumulation. These findings support the hypothesis that neoplastic transformation occurs in sequential steps and compromises proteins involved in the cell cycle control. Concordance of p53 and mdm-2 protein expression in LS and adjacent SCC provides evidence that LS can act as a precursor lesion in the absence of morphologic atypia. Overexpression of mdm-2 with stabilization and inactivation of p53 protein may provide an alternate pathway for vulvar carcinogenesis.

Abstract
We describe a very rare association between intraepithelial, extramammary Paget's disease and human papillomavirus- (HPV) negative, keratinized type of VIN III observed in two elderly women. In both cases, morphological and immunohistochemical investigation showed two heterogeneous but intimately admixed neoplastic populations of vulvar epithelium. Atypical keratinocytes stained markedly and diffusely positive for high molecular weight cytokeratins, and moderately for p53 protein and c-erbB-2 immunostainings. Paget cells were diffusely positive for CEA, EMA, and low molecular weight cytokeratins, moderately and focally for c-erbB-2 and (in one case) for S-100. Morphological and immunohistochemical phenotypic differences between Paget cells and atypical keratinocytes suggest a simultaneous and incidental association of two distinct neoplastic disorders more than a mixed carcinoma in situ of vulvar epithelium.

Abstract
The status of regional lymph nodes is a powerful predictor of survival in patients with early cancers of the vulva, cervix, and uterus. Radical resection of vulvar and cervix cancers along with extensive lymphadenectomy remains the standard of care for these cancers. Intraoperative lymphatic mapping and sentinel node identification has the potential to improve the treatment of patients with gynecologic cancer with improved detection of lymph node metastases and reduced morbidity. This chapter will focus primarily on vulvar cancer and include a review of previous innovations in treatment and current experience with intraoperative lymphatic mapping in these patients.

Abstract
OBJECTIVE Immunocompromised patients, such as female renal transplant recipients, have an increased incidence of neoplasms involving the lower genital tract (i.e., cervix, vagina, vulva). The relationship between lower genital tract neoplasms and human papillomavirus (HPV) infection has been established and high-risk oncogenic subtypes have been identified (HPV 16, 18, 45, and 56). The purpose of this study is to evaluate HPV subtypes present in lower genital tract neoplasms of post renal transplant women and compare HPV subtypes found in these patients with immunocompetent patients having similar neoplasms and normal immunocompetent controls. METHODS Twenty specimens from lower genital tract neoplasms of 16 renal transplant patients, 13 specimens from 13 immunocompetent patients with similar histology, and 13 patients with normal lower genital tract histology were analyzed for the presence of HPV using polymerase chain reaction. HPV primers including the L1 (late) region consensus primers and primers specific for the HPV E6 (early) region for subtypes 6, 11, 16, and 18 were amplified with DNA from the above patient samples. RESULTS Overall, HPV was detected in 21/46 specimens tested. Thirteen of the HPV-positive specimens were from transplant patients, and 8 were from immunocompetent patients (5 immunocompetent with disease and 3 normal patients). This difference in the total number of HPV-positive cases was statistically significant between the transplant and immunocompetent group (P = 0.02). Although no difference in HPV 6 and/or 11 was detected between the two groups, HPV subtypes 16 and/or 18 approached statistical significant difference (P = 0.06). CONCLUSIONS High-risk oncogenic HPV subtypes 16 and/or 18 were found at a higher rate in transplant patients compared with their immunocompetent counterparts. The combination of immunocompromise and increased HPV 16 and/or 18 positivity may place these patients at increased risk for aggressive lower genital tract neoplastic progression.
