Assessment of PD-L1, TROP2, and nectin-4 expression in penile squamous cell carcinoma. Hum Pathol 2023; 142:42-50. [PMID: 37977513 DOI: 10.1016/j.humpath.2023.10.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 10/17/2023] [Accepted: 10/23/2023] [Indexed: 11/19/2023]
Abstract
OBJECTIVES There is an unmet need for therapeutically relevant biomarkers for advanced penile squamous cell carcinoma (pSCC). Proposed immunohistochemistry (IHC)-based biomarkers include programmed death-ligand 1 (PD-L1), trophoblast cell-surface antigen 2 (TROP2), and nectin-4; however, there is a paucity of data pertaining to these biomarkers. Herein, we investigated the expression of PD-L1, TROP2, and nectin-4 in a well-annotated cohort of pSCCs. METHODS A single-institution pathology archive was queried for patients who had a partial or total penectomy for pSCC between January 2000 and December 2022. Whole-slide sections were stained with antibodies against PD-L1 (22C3), TROP2, and nectin-4. Expression in tumor cells was quantified using H-scores (0-300). Associations between IHC expression, human papilloma virus (HPV) status, clinicopathologic findings, and outcome parameters were evaluated. RESULTS This study included 121 patients. For PD-L1, the median combined positive and H-scores were 1 and 0, respectively; 32.7 % of the cases had an H-score>0. Compared to PD-L1-negative tumors, PD-L1-positive tumors had higher pT stage and grade. The median TROP2 and nectin-4 H-scores were 230 and 140, respectively, with high TROP2 and nectin-4, defined by an H-score>200, noted in 80.7 % and 10.9 % of cases, respectively. High-risk HPV-positive cases had higher TROP2 and nectin-4 scores compared to HPV-negative cases. Patients with high TROP2 expression had significantly more disease progression, and patients with high nectin-4 expression had significantly fewer deaths due to disease. CONCLUSIONS High expression of TROP2 and nectin-4 in pSCC support evaluation of these markers as therapeutic targets pending validation of our findings.

Detection of variable genotypes in common human papillomavirus-associated invasive penile squamous cell carcinomas: a study of 177 human papillomavirus-positive cases. Hum Pathol 2023; 139:65-72. [PMID: 37429448 DOI: 10.1016/j.humpath.2023.07.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Revised: 06/29/2023] [Accepted: 07/05/2023] [Indexed: 07/12/2023]
Abstract
Human papillomavirus (HPV) is detected in 30-50% of invasive penile carcinomas, and it is frequently associated with basaloid and warty morphological features. Based on this heterogeneity and different clinical behaviors, we hypothesized a variation in their HPV genotypic composition. To test this, we evaluated 177 HPV-positive cases: basaloid (114), warty-basaloid (28), and warty (condylomatous) (35) invasive carcinomas. HPV DNA detection and genotyping was performed using the SPF-10/DEIA/LiPA25 system. Nineteen HPV genotypes were detected. High-risk HPVs predominated (96%), and low-risk HPVs were rarely present. Most common genotype was HPV16 followed by HPVs 33 and 35. According to the genotypes identified, 93% of the cases would be covered with current vaccination programs. There was a significant variation in the distribution of HPV16 and non-HPV16 genotypes according to histological subtype. HPV16 was significantly frequent in basaloid (87%) and was less frequent in warty carcinomas (61%). This molecular difference, along with their distinctive macro-microscopic and prognostic features, makes basaloid and warty carcinomas unique. The gradual decreasing frequency of HPV16 demonstrated in basaloid, warty-basaloid, and warty carcinomas suggest that the basaloid cell, present in those types in decreasing proportions, may be responsible for the differences.

Penile intraepithelial neoplasia: Distribution of subtypes, HPV genotypes and p16 INK4a in 84 international cases. Hum Pathol 2023; 131:1-8. [PMID: 36427594 DOI: 10.1016/j.humpath.2022.11.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2022] [Revised: 11/16/2022] [Accepted: 11/16/2022] [Indexed: 11/25/2022]
Abstract
There are few pathologic or molecular studies of penile precancerous lesions, and the majority refers to lesions associated with invasive carcinomas. Penile Intraepithelial Neoplasia (PeIN) is classified in two morphologically and distinctive molecular groups, non-HPV and HPV-related with special subtypes. The primary purpose of this international series was to classify PeIN morphologically, detect HPV genotypes and determine their distribution according to PeIN subtypes. A secondary aim was to evaluate the p16INK4a immunostaining as a possible HPV surrogate for high-risk HPV infection in penile precancerous lesions. Samples consisted of 84 PeIN cases, part of a retrospective cross-sectional analysis of 1095 penile carcinomas designed to estimate the HPV DNA prevalence in penile cancers using PCR and p16INK4a immunostaining. Penile Intraepithelial Neoplasia (PeIN) was classified in HPV-related (basaloid, warty-basaloid, warty, hybrid, and mixed subtypes) and non-HPV-related (differentiated), the former being the most frequent. PeIN subtypes were differentiated (non-HPV-related) and basaloid, warty-basaloid, warty, hybrid and mixed (HPV-related). Basaloid PeIN was the most commonly diagnosed subtype, and HPV16 was the most frequent HPV genotype detected. Warty-basaloid and warty PeIN showed a more heterogeneous genotypic composition. Most HPV genotypes were high-risk but low-risk HPV genotypes were also present in a few cases (4%). A single HPV genotype was detected in 82% of HPV positive cases. In contrast, multiple genotypes were detected in the remaining 18% of cases. The findings in this study support the paradigm that penile in situ neoplasia, like its invasive counterparts, is HPV dependent or independent and has distinctive morphological subtypes readily identified in routine practice. Considering that HPV16 is clearly the predominant type, and that the three available vaccines have HPV16, all of them will be suitable for vaccination programs; the price of the vaccines will be probably the main determinant to choose the vaccine.

Abstract
"Background: Human papillomavirus (HPV) E6 and E7 oncoproteins are vital for developing HPV induced penile carcinoma. The viral oncoproteins play a central role in oncogenesis by interacting with several cellular regulatory proteins, such as p16INK4a and p53. Many studies suggest that these proteins showed clinical utility in predicting nodal disease, cancer specific survival, overall survival and even tumor grade. Understanding the molecular mechanism involved in the carcinogenesis of penile cancer could offer biomarkers for disease progression, treatment response and potential targeted therapies; (2) Methods: This paper is a prospective study on a group of 100 patients who underwent prostate surgery during 2013 and 2014 in the Urology Clinic of “Carol Davila” Central Military Emergency University Hospital Bucharest. They were tested for HPV by PCR and IHC (p16) methods; (3) Results: 11 cases (22%) of HPV were found in the cluster of patients tested. PCR and P16 were the HPV diagnostic tests used. In order to determine the consistency of the 2 tests, the Cohen’s kappa coefficient was used at a p level < 0.05. The PCR method had a sensitivity of 81.8% and a specificity of 94.9%. The P16 method had a sensitivity of 63.6% and a specificity of 89.7%."

A comprehensive analysis of penile cancer in the region with the highest worldwide incidence reveals new insights into the disease. BMC Cancer 2022; 22:1063. [PMID: 36243680 PMCID: PMC9569053 DOI: 10.1186/s12885-022-10127-z] [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: 07/05/2022] [Accepted: 09/13/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Although penile cancer (PC) is uncommon in developed countries, it is widespread in developing countries. The state of Maranhão (Northeast, Brazil) has the highest global incidence recorded for PC, and, despite its socioeconomic vulnerability, it has been attributed to human papillomavirus (HPV) infection. This study aimed to determine the histopathological features, the prevalence of HPV infection, and the immunohistochemical profile of PC in Maranhão. METHODS A retrospective cohort of 200 PC cases were evaluated. HPV detection was performed using nested-PCR followed by direct sequencing for genotyping. Immunohistochemistry (IHC) was performed using monoclonal antibodies anti-p16INK4a, p53, and ki-67. RESULTS Our data revealed a delay of 17 months in diagnosis, a high rate of penile amputation (96.5%), and HPV infection (80.5%) in patients from Maranhão (Molecular detection). We demonstrated the high rate of HPV in PC also by histopathological and IHC analysis. Most patients presented koilocytosis (75.5%), which was associated with those reporting more than 10 different sexual partners during their lifetime (p = 0.001). IHC revealed frequent p16INK4a overexpression (26.0%) associated with basaloid (p < 0.001) and high-grade tumors (p = 0.008). Interestingly, p16 appears not to be a better prognostic factor in our disease-free survival analysis, as previously reported. We also demonstrated high ki-67 and p53 expression in a subset of cases, which was related to worse prognostic factors such as high-grade tumors, angiolymphatic and perineural invasion, and lymph node metastasis. We found a significant impact of high ki-67 (p = 0.002, log-rank) and p53 (p = 0.032, log-rank) expression on decreasing patients' survival, as well as grade, pT, stage, pattern, and depth of invasion (p < 0.05, log-rank). CONCLUSIONS Our data reaffirmed the high incidence of HPV infection in PC cases from Maranhão and offer new insights into potential factors that may contribute to the high PC incidence in the region. We highlighted the possible association of HPV with worse clinical prognosis factors, differently from what was observed in other regions. Furthermore, our IHC analysis reinforces p16, ki-67, and p53 expression as important diagnosis and/or prognosis biomarkers, potentially used in the clinical setting in emerging countries such as Brazil.

Abstract
Objectives: To establish the level of access to healthcare, education, social and geographical factors predisposing a negative surgical outcome and higher mortality rate in patients with penile cancer. Methods: This is a retrospective, longitudinal and analytical study. Ninety-three medical records of adult male patients diagnosed with penile cancer were reviewed. Fisher’s exact test was performed to determine the association between the level of healthcare, social and geographical factors, and the outcomes for penile cancer. Results: Patients without primary care access had a higher chance of having lymphovascular invasion at the time of diagnosis (OR=37.5, P<0.0001), a higher mortality rate at 24 months after diagnosis (OR=19.2, P=0.005), a lack of high school diploma or equivalent (OR=3.8, P=0.049) and a higher likelihood of referral from a provincial hospital (OR=10.1, P<0.0001). Patients without a favorable surgical outcome (radical penectomy) were more likely to have been referred from a provincial hospital (OR=6.8, P<0.0001) and not have access to a primary care center (OR=149.5, P<0.0001), a tertiary care center (OR=20.7, P=0.003), and a high school diploma (OR=7.9, P=0.004). Conclusions: The lack of access to primary care is strongly associated with vascular invasion at diagnosis, lower educational level, a referral from provincial zones, and a higher mortality rate at 24 months. Patients who did not have access to primary and tertiary care, a high school diploma, and were referred from the province were more likely to have a radical penectomy.

Abstract
Objective The aim of the study was to present a case of penile squamous cell carcinoma and immunohistochemical identification and evaluation of E-cadherin and β-catenin expression. Methods We are presenting a 70-year old man with a variant of penile squamous cell carcinoma with mixed warty and basaloid features. After diagnosis, the patient underwent partial penectomy. Samples taken from the material after surgery were subjected to basic histological staining and immunohistochemical identification of E-cadherin and β-catenin. A Real-time PCR study was conducted to investigate the expression of E-cadherin and β-catenin. Results Routine histopathological examinations revealed the characteristic features of warty-basaloid squamous cell carcinoma. In the case studied, a positive immunohistochemical reaction was observed for E-cadherin and β-catenin. QRT-PCR analysis showed a statistically significant decrease in E-cadherin expression in tumor samples compared to healthy tissue. In contrast, expression of the gene encoding β-catenin was slightly higher in tumor samples compared to normal tissue. Conclusions The reduced level of the complex of adhesive elements, E-cadherin-β-catenin, disturbs cell differentiation, promotes a more invasive phenotype-stromal infiltration and the formation of distant metastases. In the described case of the penile tumor, a decrease in E-cadherin expression was noted, which could be related to the occurrence of neoplastic infiltration of the spongy body space. In summary, E-cadherin and β-catenin expression and the immunoreactivity of these proteins are expressed at different levels in tumor cells and in penile interstitial cells. Regulation of expression during various physiological and pathophysiological processes indicates a potentially important role of E-cadherin and β-catenin in cell proliferation and adhesion.

Abstract
Background The high-risk human papillomavirus (HPV) infection represents one of the main etiologic pathways of penile carcinogenesis in approximately 30–50 % of cases. Several techniques for the detection of HPV are currently available including Polymerase chain reaction-based techniques, DNA and RNA in situ hybridization (ISH), p16 immunohistochemistry (IHC). The multiplex HPV RNA ISH/p16 IHC is a novel technique for the simultaneous detection of HPV E6/E7 transcripts and p16INK4a overexpression on the same slide in a single assay. The main aim of this study was to evaluate the discrepancy of p16 IHC expression relatively to HPV RNA ISH in penile cancer tissue. Methods We collected a series of 60 PCs. HPV has been analysed through the RNA ISH, p16 IHC and the multiplex HPV RNA ISH/p16 IHC. Results The multiplex HPV RNA ISH /p16 IHC results in the series were in complete agreement with the previous results obtained through the classic p16 IHC and HPV RNA scope carried out on two different slides. The multiplex HPV RNA ISH /p16 IHC showed that HPV positivity in our series is more frequently in usual squamous cell carcinoma than in special histotypes (19 out of 60 − 15 %- versus 6 out of 60 − 10 %-), in high-grade than in moderate/low grade carcinomas (6 out of 60 − 10 %- versus 4 out of 60 − 6.7 %-). In addition, our data revealed that in 5 out of 20 cases with p16 high intensity expression is not associated with HPV RNA ISH positivity. Conclusions Our findings emphasize that the use of p16 as a surrogate of HPV positivity was unsuccessful in approximatively 8 % of cases analysed in our series. Indeed, p16 IHC showed a sensitivity of 100 % and a specificity of 71 %, with a positive predictive value (PPV) of 54 % and a negative predictive value of 100 %; when considering high intensity, p16 IHC showed a sensitivity of 100 %, a specificity of 89 %, with a PPV of 75 % and NPV of 100 %. Since HPV positivity could represent a relevant prognostic and predictive value, the correct characterization offered by this approach appears to be of paramount importance.

Abstract
Penile cancer is an under-studied disease that occurs more commonly in developing countries and 30-50% of cases show high-risk human papillomavirus (HPV) infection. Therapeutic advances are slow, largely due to the absence of animal models for translational research. Here, we report the first mouse model for HPV-related penile cancer. Ten-week-old mice expressing all the HPV16 early genes under control of the cytokeratin 14 (Krt14) gene promoter and matched wild-type controls were exposed topically to dimethylbenz(a)anthracene (DMBA) or vehicle for 16 weeks. At 30 weeks of age, mice were sacrificed for histological analysis. Expression of Ki67, cytokeratin 14, and of the HPV16 oncogenes E6 and E7 was confirmed using immunohistochemistry and quantitative PCR, respectively. HPV16-transgenic mice developed intraepithelial lesions including condylomas and penile intraepithelial neoplasia (PeIN). Lesions expressed cytokeratin 14 and the HPV16 oncogenes E6 and E7 and showed deregulated cell proliferation, demonstrated by Ki67-positive supra-basal cells. HPV16-transgenic mice exposed to DMBA showed increased PeIN incidence and squamous cell carcinoma. Malignant lesions showed varied histological features closely resembling those of HPV-associated human penile cancers. Wild-type mice showed no malignant or pre-malignant lesions even when exposed to DMBA. These observations provide the first experimental evidence to support the etiological role of HPV16 in penile carcinogenesis. Importantly, this is the first mouse model to recapitulate key steps of HPV-related penile carcinogenesis and to reproduce morphological and molecular features of human penile cancer, providing a unique in vivo tool for studying its biology and advancing basic and translational research. © 2020 Pathological Society of Great Britain and Ireland.

Abstract
Human papillomavirus (HPV) infection appears to play an important role in the development of penile cancer (PeCa), but their relationship remains unclear. Therefore, we performed a systematic review and meta-analysis to elucidate their relationship. We systematically searched Embase, PubMed, Cochrane Library, and Web of Science for case-control studies and cross-sectional studies using polymerase chain reaction (PCR) technology on formalin-fixed paraffin-embedded (FFPE) or paraffin-embedded (PE) PeCa tissues to detect HPV (published between January 1, 2007, and December 29, 2017; no language restrictions). Twenty-two studies were identified, and 1664 cases were available for analysis. The combined HPV infectious risk of PeCa is 51.0% (95% confidence interval [CI]: 43.0%–60.0%). The three most common subtypes of HPV were HPV16 (28.5%), HPV18 (2.3%), and HPV6 (2.3%). The virus was relevantly associated with basaloid (85.5%, 95% CI: 77.2%–93.8%) and warty (50.0%, 95% CI: 35.2%–64.8%) carcinomas. The invasiveness of PeCa was not associated with HPV (χ2 = 0.181, df = 1, P < 0.671). HPV infection in PeCa tended to be moderately differentiated (54.4%, 95% CI: 47.7%–61.1%). This study found that almost half of PeCa patients are associated with HPV. The most commonly associated genotype is HPV16, but several other genotypes were also detected. In addition to types 6 and 11, other single low-risk HPV infections have been found to contribute to PeCa to a lesser degree. HPV-positive tumors tend to exhibit warty and/or basaloid features, corresponding to a moderate histological grade. The role of HPV in PeCa should be revisited to provide evidence for the development of PeCa in the presence of HPV infection.

Abstract
Since the seminal study of Hart and Helwig in 1975, there are few detailed pathological studies of lichen sclerosus (LS). The aims of this study were to provide a detailed histopathological description of penile LS, as well as to explore its relationship with penile intraepithelial neoplasia (PeIN) or invasive carcinoma. We evaluated 200 patients and designed a topographical approach for the histological evaluation focusing in alterations of the following anatomical layers: squamous epithelium, lamina propria, dartos, and corpus spongiosum. We documented the quantity and topographical location of stromal lymphocytes. The prevalent lesions found were epithelial hyperplasia, atrophy, PeIN, basal cell vacuolization, lamina propria sclerosis, and variable patterns of lymphocytic infiltration. Various unique patterns of stromal sclerosis were described: perivascular, globular, linear, and solid fibrosis/hyalinization; any of them were found to be diagnostic for LS. The variation in the topography and density of lymphocytes was determinant for the identification of LS morphological variants: lichenoid, band-like, lymphocytic depleted, and mixed. A major finding was the identification of the variant designated as lymphocytic depleted LS, which we considered as the morphological prototype of LS associated with penile neoplasia. The detailed description of this complex lesion presented in this study may help pathologists in practice to identify and better define LS. The identification of the special variants suggests a role of the stromal lymphocytes in the process of carcinogenesis. Confirmation of the observations with more studies is necessary to determine the significance of these findings.

Abstract
Penile intraepithelial neoplasia (PeIN) is currently classified in human papillomavirus (HPV)- and non-HPV-related subtypes with variable HPV genotypes. PeINs are frequently associated with other intraepithelial lesions in the same specimen. The aim of this study was to detect and compare HPV genotypes in PeINs and associated lesions using high-precision laser capture microdissection-polymerase chain reaction and p16INK4a immunostaining. We evaluated resected penile specimens from 8 patients and identified 33 PeINs and 54 associated lesions. The most common subtype was warty PeIN, followed by warty-basaloid and basaloid PeIN. Associated lesions were classical condylomas (17 cases), atypical classical condylomas (2 cases), flat condylomas (9 cases), atypical flat condylomas (6 cases), flat lesions with mild atypia (12 cases), and squamous hyperplasia (8 cases). After a comparison, identical HPV genotypes were found in PeIN and associated lesions in the majority of the patients (7 of 8 patients). HPV16 was the most common genotype present in both PeIN and corresponding associated lesion (50% of the patients). Nonspecific flat lesions with mild atypia, classical condylomas, and atypical condylomas were the type of associated lesions most commonly related to HPV16. Other high-risk HPV genotypes present in PeIN and associated nonspecific flat lesion with mild atypia were HPV35 and HPV39. In this study of HPV in the microenvironment of penile precancerous lesions, we identified identical high-risk HPV genotypes in PeIN and classical, flat, or atypical condylomas and, specially, in nonspecific flat lesions with mild atypia. It is possible that some of these lesions represent hitherto unrecognized precancerous lesions.

Abstract
Two major pathways of penile carcinogenesis are known: human papillomavirus (HPV)-induced penile cancer and HPV-negative cancers associated with chronic dermatoses. Therefore, modern measures for prevention of penile cancer may for example include prophylactic HPV vaccination. The resulting B‑cell-mediated immunity to HPV capsid proteins is effective protection against future HPV infections. Contrarily when treating existing HPV infections or HPV-associated cancers an antigen-specific T‑cell immunity is necessary. To date, screening and treatment of precancerous lesions to prevent penile cancer are not established in the German health care program and the highly expected therapeutic HPV vaccines are still on the horizon. In this article, we focus on possible strategies to prevent HPV-related penile cancer on different levels of carcinogenesis.

Abstract
BACKGROUND Infection with human papillomavirus (HPV) is reported to be present in 30-50% of penile cancer cases. The immunohistochemical test for p16INK4a is used as an indicator of the presence of HPV and as a prognostic marker for squamous cell carcinomas in various sites. However, the role of this marker in penile carcinoma has not yet been completely elucidated. The aim of this study was to analyze whether the expression of p16INK4a is associated with the presence of HPV, histological parameters, and survival in penile cancer. METHODS A study was conducted from 2014 to 2016 that included 55 patients with penile carcinoma. HPV DNA was detected through PCR using fresh tumor tissue, and immunohistochemistry was performed for analysis of p16INK4a protein using paraffin-embedded tissue. Evaluation of histological parameters was performed following complete embedding of the tumor tissue in paraffin. RESULTS HPV DNA (low-risk and high-risk genotypes) was found in 49 (89.1%) cases, and 46/49 (93.9%) showed high-oncogenic risk HPV (HR-HPV). Of the 22 cases positive for p16INK4a, HR-HPV DNA was present in 21 (95.5%) (p = 0.032). Regarding histological parameters, p16INK4a and HR-HPV were significantly associated only with tumor subtype (p = 0.036 and p = 0.032, respectively); all carcinomas with basaloid characteristics were positive for p16INK4a. Although HPV+ patients had a higher disease-free survival (p <0.001), p16INK4a expression was not associated with patient survival. CONCLUSIONS Our study, using fresh tissue samples, showed the highest incidence of HPV compared to that observed in the literature. Expression of the p16INK4a protein was significantly associated with the presence of HR-HPV and this expression may serve as a marker for the presence of the virus. The p16INK4a protein was not associated with the histological prognostic parameters, with the exception of tumor subtype, nor with patient survival. In the results, we showed that the objective of the present study was reached.

Abstract
Background The tumor draining lymph node concept was first described in penile cancer for staging. Immunohistochemistry and histopathology evaluations are routinely used in clinical practice to examine lymph nodes for metastasis. However, these methods are time-consuming with low diagnostic accuracy and micro-metastases might be missed. In this study, we aim to evaluate detection of metastatic cells in draining lymph nodes by flow cytometry. Methods To assess the sensitivity of micro-metastasis detection by FACS (Fluorescence-activated cell sorting), HeLa cells were titrated into Peripheral blood mononuclear cells (PBMCs) and expression of pan-cytokeratin AE1/AE3 was analyzed. Single cell suspensions were separately prepared from 10 regional lymph nodes obtained from 5 patients with invasive penile cancer undergoing radical surgery and lymph node dissection. Lymph node dereived cells were examined for cell surface expression of EpCAM, E-cadherin and intracellular expression of pan-cytokeratin AE1/AE3 by FACS. Results Ten lymph nodes from 5 penile cancer patients were investigated in a head-to-head comparison between FACS and pathology examination of sections. All metastatic lymph nodes verified by pathology examination were also identified by FACS. Two additional lymph nodes with micro-metastases were diagnosed by FACS only. Conclusions FACS analyses of pan-cytokeratin AE1/AE3 stained single cells from tumor draining lymph nodes can be used to detect micro-metastases in patients with penile cancer patients.

Abstract
Androgen receptor (AR) is a member of the steroid and nuclear family receptor that acts as transcription factor. AR signaling plays pivotal role in the development and progression of prostate cancer. However, the role of AR in penile cancer (PeCa) is poorly explored. Our previous molecular studies unveiled frequent AR mRNA loss in PeCa, which was further predicted as a major driver alteration in this neoplasm. Herein, we assessed the AR protein expression in 59 usual PeCa tissues and 42 surrounding normal tissues (SNT) by immunohistochemistry using a tissue microarray. In a paired analysis, we found a total absence of nuclear AR expression in PeCa while 95.2% of SNT samples presented strong nuclear AR expression (P < 0.001). Interestingly, 17 of 42 PeCa presented weak or moderate cytoplasmic AR staining, contrasting with 5 of 42 SNT (P = 0.008). Increased levels of AR cytoplasmic expression were related with poor prognosis features including advanced clinical staging (P = 0.044), compromised surgical margins (P = 0.005), and pathological inguinal node status (P = 0.047). Furthermore, AR cytoplasmic expression was also related with shorter overall survival (P = 0.032). In conclusion, the frequent loss of nuclear AR protein levels suggests a potential function in PeCa development. Based on this result, the androgen deprivation therapy is not indicated for PeCa patients. In addition, the AR cytoplasmic expression found in a significant number of cases (40.5%) showed prognostic value and pathways activated by the non-genomic AR signaling may represent a promising therapeutic strategy.

Abstract
Background Penile carcinoma (PC) is a rare, highly mutilating disease, common in developing countries. The evolution of penile cancer includes at least two independent carcinogenic pathways, related or unrelated to HPV infection. Objectives To estimate the prevalence, identify HPV genotypes, and correlate with clinicopathological data on penile cancer. Methods A retrospective cohort study involving 183 patients with PC undergoing treatment in a referral hospital in Goiânia, Goiás, in Midwestern Brazil, from 2003 to 2015. Samples containing paraffin embedded tumor fragments were subjected to detection and genotyping by INNO-LiPA HPV. The clinicopathological variables were subjected to analysis with respect to HPV positivity and used prevalence ratio (PR), adjusted prevalence ratio (PRa) and 95% confidence interval (CI) as statistical measures. Results The prevalence of HPV DNA in PC was 30.6% (95% CI: 24.4 to 37.6), high-risk HPV 24.9% (95% CI: 18.9 to 31.3), and 62.5% were HPV 16. There was a statistical association between the endpoints HPV infection and HPV high risk, and the variable tumor grade II-III (p = 0.025) (p = 0.040), respectively. There was no statistical difference in disease specific survival at 10 years between the HPV positive and negative patients (p = 0.143), and high and low risk HPV (p = 0.325). Conclusions The prevalence of HPV infection was 30.6%, and 80.3% of the genotypes were identified as preventable by anti-HPV quadrivalent or nonavalent vaccine. HPV infections and high-risk HPV were not associated with penile carcinoma prognosis in this study.

Abstract
The International Society of Urological Pathology (ISUP) held an expert-driven penile cancer conference in Boston in March 2015, which focused on the new World Health Organisation (WHO) classification of penile cancer: human papillomavirus (HPV)-related tumours and histological grading. The conference was preceded by an online survey of the ISUP members, and the results were used to initiate discussions. Because of the rarity of penile tumours, this was not a consensus but an expert-driven conference aimed at assisting pathologists who do not see these tumours on a regular basis. After a justification for the novel separation of penile squamous cell carcinomas into HPV-related and non-HPV-related-carcinomas, the histological classification of penile carcinoma was proposed; this system was also accepted subsequently by the WHO for subtyping of penile carcinomas (2016). A description of HPV-related neoplasms, which may be recognised by their histological features, was presented, and p16 was recommended as a surrogate indicator of HPV. A three-tier grading system was recommended for penile squamous carcinomas; this was also adopted by the WHO (2016). Many of the distinctive histological subtypes of squamous cell carcinoma of the penis are associated with distinct grades, based on the squamous cell carcinoma subtype histological features.

Human Papillomavirus (HPV) Genotypes in Condylomas, Intraepithelial Neoplasia, and Invasive Carcinoma of the Penis Using Laser Capture Microdissection (LCM)-PCR: A Study of 191 Lesions in 43 Patients.

Abstract
Laser capture microdissection-polymerase chain reaction (LCM-PCR) supported by p16 was used for the first time to demonstrate human papillomavirus (HPV) DNA in histologically specific penile lesions, which were as follows: squamous hyperplasia (12 lesions, 10 patients), flat lesions (12 lesions, 5 patients), condylomas (26 lesions, 7 patients), penile intraepithelial neoplasia (PeIN) (115 lesions, 43 patients), and invasive squamous cell carcinomas (26 lesions, 26 patients). HPV was detected by whole-tissue section and LCM-PCR. LCM proved to be more precise than whole-tissue section in assigning individual genotypes to specific lesions. HPV was negative or very infrequent in squamous hyperplasia, differentiated PeIN, and low-grade keratinizing variants of carcinomas. HPV was strongly associated with condylomas, warty/basaloid PeIN, adjacent flat lesions, and warty/basaloid carcinomas. A single HPV genotype was found in each lesion. Some condylomas and flat lesions, especially those with atypia, were preferentially associated with high-risk HPV. Unlike invasive carcinoma, in which few genotypes of HPV were involved, there were 18 HPV genotypes in PeIN, usually HPV 16 in basaloid PeIN but marked HPV heterogeneity in warty PeIN (11 different genotypes). Variable and multiple HPV genotypes were found in multicentric PeIN, whereas unicentric PeIN was usually related to a single genotype. There was a correspondence among HPV genotypes in invasive and associated PeIN. p16 was positive in the majority of HPV-positive lesions except condylomas containing LR-HPV. p16 was usually negative in squamous hyperplasia, differentiated PeIN, and low-grade keratinizing variants of squamous cell carcinomas. In summary, we demonstrated that LCM-PCR was a superior research technique for investigating HPV genotypes in intraepithelial lesions. A significant finding was the heterogeneity of HPV genotypes in PeIN and the differential association of HPV genotypes with subtypes of PeIN. The presence of atypia and high-risk HPV in condylomas and adjacent flat lesions suggests a precursor role, and the correspondence of HPV genotypes in invasive carcinomas and associated PeIN indicates a causal relation. Data presented support the bimodal hypothesis of penile cancer carcinogenesis in HPV-driven and non-HPV-driven carcinomas and justify the current WHO pathologic classification of PeIN in special subtypes.

Abstract
Penile clear cell carcinoma originating in skin adnexal glands has been previously reported. Here, we present 3 morphologically distinctive penile tumors with prominent clear cell features originating not in the penile skin but in the mucosal tissues of the glans surface squamous epithelium. Clinical and pathologic features were evaluated. Immunohistochemical stains were GATA3 and p16. Human papilloma virus (HPV) detection by in situ hybridization was performed in 3 cases, and whole-tissue section-polymerase chain reaction was performed in 1 case. Patients' ages were 52, 88, and 95 years. Tumors were large and involved the glans and coronal sulcus in all cases. Microscopically, nonkeratinizing clear cells predominated. Growth was in solid nests with comedo-like or geographic necrosis. Focal areas of invasive warty or basaloid carcinomas showing in addition warty or basaloid penile intraepithelial neoplasia were present in 2 cases. There was invasion of corpora cavernosa, lymphatic vessels, veins, and perineural spaces in all cases. p16 was positive, and GATA3 stain was negative in the 3 cases. HPV was detected in 3 cases by in situ hybridization and in 1 case by polymerase chain reaction. Differential diagnoses included other HPV-related penile carcinomas, skin adnexal tumors, and metastatic renal cell carcinoma. Features that support primary penile carcinoma were tumor location, concomitant warty and/or basaloid penile intraepithelial neoplasia, and HPV positivity. Clinical groin metastases were present in all cases, pathologically confirmed in 1. Two patients died from tumor dissemination at 9 and 12 months after penectomy. Clear cell carcinoma, another morphologic variant related to HPV, originates in the penile mucosal surface and is probably related to warty carcinomas.

Abstract
Introduction: Human papillomavirus (HPV), belonging to the Papovavirida family, is the most prevalent sexually transmitted disease (STD) agent worldwide. In Brazil, it is estimated that there are 3-6 million people infected with HPV. Aim: The aim of this study was to evaluate the knowledge of young male students about penis cancer related to HPV infection. Methods: This exploratory and quantitative study was conducted to analyze answers of 242 male students attending a private college located in Uberaba city, Minas Gerais state, Brazil, during 2015. Results: Most of the 242 participants (88.8%) affirmed having started sexual life very early, the majority (79.3%) were currently married and 69.8% had a single sexual partner. Regardless of their knowledge about HPV virus and its relationship with penis cancer, our data showed a general lack of awareness of the participants. Conclusion: Our results suggest that despite efforts to propagate information about HPV infection and its relation to penis cancer, the level of knowledge of students is low. Because of that, it is important to improve the information spread by media, emphasizing prevention and treatment of HPV infection in men.

Abstract
Insulin-like growth factor-1 receptor (IGF1R) plays a key role in cell growth and transformation. It is overexpressed in several solid tumors. This study evaluates IGF1R immunoexpression in penile squamous cell carcinoma (SCC). Four tissue microarrays were built from formalin-fixed, paraffin-embedded blocks of 112 penile SCC from Paraguay. Membranous IGF1R expression was evaluated by immunohistochemistry using two different approaches. An H-score was calculated in each spot (stain intensity by extent), and a median score per tumor was obtained. The second approach consisted of a score similar to the scoring system that was used for evaluating HER2 immunoexpression. For each case, the highest category obtained at any spot was used for statistical analyses. IGF1R expression was compared by histologic subtype, grade, and human papillomavirus (HPV) status. Median H-score was 22.5. The distribution of IGF1R expression by HER2 approach was as follows: 0 in 33.0% cases, 1+ in 46.4%, 2+ in 14.3%, and 3+ in 6.2%. IGF1R H-scores were associated with basaloid and warty/basaloid subtypes (p = 0.0026) and higher grade (p = 0.00052). Although weaker when using the HER2 approach, the association of IGF1R expression with subtype (p = 0.015) and grade (p = 0.015) remained significant. Furthermore, there was an association between IGF1R expression by HER2 approach and HPV status (p = 0.012). IGF1R was expressed in about two thirds of penile SCC cases, showing a strong positive association with histologic grade, subtype, and HPV status. Considering that grade is a predictor of outcome IGF1R expression may have prognostic relevance and could point to a potential role for IGF1R inhibitors in treating penile SCC.

Abstract
Penile squamous cell carcinoma (PSCC) is a rare cancer, but is more common in developing countries. Locally advanced and metastatic PSCC is associated with significant morbidity and mortality, with the prognosis remaining extremely poor. The authors searched PubMed and published abstracts for metastatic PSCC studies to describe emerging therapies. Multimodality treatment using chemotherapy, radiation, and consolidative surgery are standard of care. Utilizing anti-EGFR therapies and novel immunotheraputic approaches may help improve outcomes in PSCC.

Abstract
Penile squamous cell carcinoma (PeSCCA) is a rare malignancy for which there are limited treatment options due to a poor understanding of the molecular alterations underlying disease development and progression. Therefore, we performed comprehensive, targeted next-generation sequencing to identify relevant somatic genomic alterations in a retrospective cohort of 60 fixed tumor samples from 43 PeSCCA cases (including 14 matched primary/metastasis pairs). We identified a median of two relevant somatic mutations and one high-level copy-number alteration per sample (range, 0-5 and 0-6, respectively). Expression of HPV and p16 was detectable in 12% and 28% of patients, respectively. Furthermore, advanced clinical stage, lack of p16 expression, and MYC and CCND1 amplifications were significantly associated with shorter time to progression or PeSCCA-specific survival. Notably, four cases harbored EGFR amplifications and one demonstrated CDK4 amplification, genes for which approved and investigational targeted therapies are available. Importantly, although paired primary tumors and lymph node metastases were largely homogeneous for relevant somatic mutations, we identified heterogeneous EGFR amplification in primary tumor/lymph node metastases in 4 of 14 cases, despite uniform EGFR protein overexpression. Likewise, activating HRAS mutations occurred in 8 of 43 cases. Taken together, we provide the first comprehensive molecular PeSCCA analysis, which offers new insight into potential precision medicine approaches for this disease, including strategies targeting EGFR.

Abstract
Which subtype(s) of high-risk human papillomavirus (hrHPV) are involved in squamous cell carcinoma (SCC) of the scrotum is unknown. Twenty-seven cases of SCC of the scrotum were retrieved, and all 15 subtypes of hrHPV and their viral loads were assessed using multiplex real-time polymerase chain reaction. The results were correlated with the histopathologic features, p16 expression, and in situ hybridization for hrHPV. hrHPV was identified in 18 (67%) of 27 of the cases, including HPV16 (n=8), HPV35 (n=7), HPV31 (n=5), HPV59 (n=5), HPV33 (n=3), HPV18 (n=2), HPV51 (n=2), HPV39 (n=1), HPV56 (n=1), and HPV82 (n=1). Of the 18 cases, 10 (56%) were infected by multiple hrHPV subtypes. In situ carcinomas had higher viral loads than invasive (50M versus 2M in average). The average age of HPV-positive and -negative cases was similar, 55 and 51, respectively. Of 11 cases of invasive carcinoma, 5 (45%) were positive for hrHPV versus 13 of 16 (81%) of in situ carcinomas. The highest proportion of hrHPV-positive cases was seen in basaloid type (7/7; 100%) and warty type (4/4; 100%), followed by usual type (7/16; 44%). Of 18 of the HPV-positive cases, 9 (50%) were also positive for p16 by immunohistochemistry and 6 of 18 (33%) were positive by in situ hybridization. Similar to SCC of the vulva and penis, the most frequently HPV-positive tumors are basaloid and warty types. However, a proportion of SCC usual type are also positive for hrHPV. Our results show that 8 (44%) of 18 of cases are associated with hrHPV subtypes other than 16 and 18. Additionally, 7 (70%) of 10 of hrHPV16/18-positive cases are coinfected with other subtypes.

Abstract
OBJECTIVE To evaluate the prevalence and genotypes of human papillomavirus (HPV) infection and microbiological status of the foreskin in asymptomatic prepubertal boys. METHODS A total of 100 prepubertal healthy boys who underwent a standard circumcision procedure were included in the study. High-risk HPV status was determined by real-time polymerase chain reaction for the genotypes 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68. The swabs were immediately sent to microbiology laboratory for culture and sensitivity tests. RESULTS The median age at the time of surgery was 5.7 years (range, 2 months-9 years). High-risk HPV was detected in 9 foreskins (9%). Positive samples showed are HPV16 (n = 3), 31 (n = 2), 39 (n = 3), and 51 (n = 1). There were a total of 72 organism isolates: 54 gram-positive (75%) and 17 gram-negative (23.6%) bacteria and 1 (1.4%) Candida. The most commonly isolated gram-negative bacterium was Escherichia coli (41.2%), whereas the commonly isolated gram-positive bacterium was Enterecoccus sp. (57.4%). CONCLUSION Our results showed that subclinical high-risk HPV infections are found in the foreskin, which could be a reservoir for HPV-associated diseases, and smegma seems not to be a risk factor for drug-resistant infection in children.

Abstract
Penile carcinoma is a rare genitourinary malignancy in North America and Europe with highest rates recorded in South America, Africa and Asia. Recent classifications have refined the terminology used in classifying intraepithelial/in situ lesions and additionally newer entities have been recognised in the invasive category. While increasing recognition of a bimodal pathway of penile carcinogenesis has facilitated understanding and classification of these tumours, handling and subtyping of penile malignancies presents a challenge to the reporting pathologist, in part due to their rarity. This article reviews the terminology and classification of in situ and invasive carcinomas and their relationship to human papilloma virus status. In addition, associated non-neoplastic dermatological conditions of relevance and appropriate ancillary investigations will be addressed.

Abstract
ARID1A, a member of the chromatin remodeling genes family, has been suggested as a novel tumor suppressor gene in gynecologic malignancies. However, its role in penile cancer has yet to be determined. This study assesses the immunohistochemical expression of ARID1A in penile squamous cell carcinoma (SCC) and its association with pathologic features, human papillomavirus (HPV) status, and previously reported mammalian target of rapamycin pathway markers in the same cohort. Four tissue microarrays were constructed from 112 cases of formalin-fixed, paraffin-embedded penile SCC from Paraguay. Each tumor was sampled 3 to 12 times. ARID1A expression was evaluated by immunohistochemistry using a polyclonal rabbit anti-ARID1A (BAF250A) antibody. An H score was calculated in each spot as the sum of expression intensity (0-3+) by extent (0%-100%). Median H score per case was used for statistical analysis. ARID1A expression was observed in all cases, ranging from 3% to 100% of tumor cells (median, 95%). In 96 cases (86%), ARID1A expression was observed in 90% or more tumor cells. HPV DNA was detected in 20 (38%) of 52 analyzed samples. There was a significant trend of association between ARID1A and histologic grade. ARID1A expression was not associated with histologic subtype (P = .61) or HPV status (P = .18). ARID1A expression decreased with decreasing levels of PTEN expression (P = .01). ARID1A was expressed in penile SCC, in most cases at high levels. A significant trend of association was found between histologic grade and ARID1A expression, with lower ARID1A expression, lower histologic grades, and decreased PTEN expression.

Abstract
Penile squamous cell carcinoma (PSCC) is a rare tumor associated with high-risk human papillomavirus (HR-HPV) infection in 30% to 60% of cases. Altered expression of miRNAs has been reported in HPV-related cervical and head and neck cancers, but such data have not been available for PSCC. We analyzed a series of 59 PSCCs and 8 condylomata for presence of HPV infection, for p16(INK4a), Ki-67, and p53 immunohistochemical expression, and for expression of a panel of cellular miRNAs (let-7c, miR-23b, miR-34a, miR-145, miR-146a, miR-196a, and miR-218) involved in HPV-related cancer. HR-HPV DNA (HPV16 in most cases) was detected in 17/59 (29%) PSCCs; all penile condylomata (8/8) were positive for low-risk HPV6 or HPV11. HR-HPV(+) PSCCs overexpressed p16(INK4a) in 88% cases and p53 in 35% of cases, whereas HR-HPV(-) PSCCs were positive for p16(INK4a) and p53 immunostaining in 9% and 44% of cases, respectively. Among the miRNAs investigated, expression of miR-218 was lower in PSCCs with HR-HPV infection and in p53(-) cancers. Hypermethylation of the promoter of the SLIT2 gene, which contains miR-218-1 in its intronic region, was frequently observed in PSCCs, mainly in those with low miR-218 expression. Epigenetic silencing of miR-218 is a common feature in HR-HPV(+) PSCCs and in HR-HPV(-) PSCCs without immunohistochemical detection of p53.

Abstract
Penile cancer is a rare disease, accounting for ~1% of all malignancies in men. Poor awareness of the condition among the public and clinicians often causes long delays in diagnosis and treatment, which may result in the development of advanced disease that might require extensive and emasculating surgery. In the UK, the development of supraregional penile cancer centres has pooled resources and expertise, which has led to considerable improvements in our understanding and management of this rare condition over the past decade. However, significant gaps in our knowledge still exist. Several areas of diagnosis and management remain areas of controversy, ranging from preventive strategies and treatment of premalignant disease to the assessment of lymph node involvement and the management of advanced disease.

Abstract
OBJECTIVES To evaluate the prevalence, distribution and association of HPV with histological pattern of worse prognosis of penile cancer, in order to evaluate its predictive value of inguinal metastasis, as well as evaluation of other previous reported prognostic factors. MATERIAL AND METHODS Tumor samples of 82 patients with penile carcinoma were tested in order to establish the prevalence and distribution of genotypic HPV using PCR. HPV status was correlated to histopathological factors and the presence of inguinal mestastasis. The influence of several histological characteristics was also correlated to inguinal disease-free survival. RESULTS Follow-up varied from 1 to 71 months (median 22 months). HPV DNA was identified in 60.9% of sample, with higher prevalence of types 11 and 6 (64% and 32%, respectively). There was no significant correlation of the histological characteristics of worse prognosis of penile cancer with HPV status. Inguinal disease-free survival in 5 years did also not show HPV status influence (p = 0.45). The only independent pathologic factors of inguinal metastasis were: stage T ≥ T1b-T4 (p = 0.02), lymphovascular invasion (p = 0.04) and infiltrative invasion (p = 0.03). CONCLUSIONS HPV status and distribution had shown no correlation with worse prognosis of histological aspects, or predictive value for lymphatic metastasis in penile carcinoma.

Abstract
PURPOSE The incidence of penile cancer is four times higher in Paraguay than in the United States or Europe. There are no adequate scientific explanations for this geographical variation. The goal of this study was to evaluate the interplay among risk factors, morphology of the primary tumor, and HPV status. METHODS Information on socioeconomic status, education level, habits, and sexual history was obtained in 103 Paraguayan patients with penile cancer. All patients were then treated by surgery, and specimens were evaluated histopathologically. RESULTS Patients usually dwelled in rural/suburban areas (82%), lived in poverty (75%), had a low education level (91%), and were heavy smokers (76%). Phimosis (57%), moderate/poor hygienic habits (90%), and history of sexually transmitted diseases (74%) were frequently found. Patients with >10 lifetime female partners had an odds ratio of 3.8 (95% CI 1.1, 12.6; P-trend = .03) for presenting HPV-positive tumors when compared to patients with <6 partners. However, this trend was not significant when the number of sexual partners was adjusted for age of first coitus and antecedents of sexually transmitted diseases. HPV-related tumors (found in 36% of the samples) were characterized by a warty and/or basaloid morphology and high histological grade in most cases. CONCLUSIONS In our series, patients with penile cancer presented a distinctive epidemiologic and pathologic profile. These data might help explaining the geographical differences in incidence and aid in the design of strategies for cancer control in Paraguay.

Abstract
The outcome of penile cancer is proportional to the stage at presentation. Strategies aimed at primary prevention would have a clear advantage, both for the individual and in terms of health economics. A number of preventative measures could be employed, including circumcision, smoking cessation, education on hygiene and human papillomavirus (HPV) prevention. There is a high prevalence of HPV infection associated with penile cancer worldwide. The recent development of HPV vaccines has facilitated interest in their use for the prevention of penile cancer. In this article we review the literature surrounding penile cancer prevention and HPV vaccination in men.

Abstract
OBJECTIVES Infection by high-risk human papillomavirus (HR-HPV) plays an important role in the pathogenesis of penile cancer in approximately 50% of the patients. The gold standard for human papillomavirus (HPV) detection is the polymerase chain reaction (PCR) assay. However, technical requirements and associated costs preclude the worldwide use of PCR assays on a routine basis. Herein, we evaluated the predictive abilities of tumor morphology, immunohistochemistry for p16(INK4a) expression, and in situ hybridization (ISH) for HR-HPV detection in defining HPV status, as established by PCR. MATERIALS AND METHODS Tissue samples from 48 patients with HPV-positive penile squamous cell carcinoma (SCC) were included in 4 tissue microarrays (TMA). RESULTS Sensitivities and specificities were as follows: tumor morphology, 70% and 68%; p16(INK4a) immunohistochemistry, 65% and 90%; HR-HPV ISH, 47% and 100%. Regarding combinations of the predictors, the best performance was seen when HR-HPV ISH and p16(INK4a) immunohistochemistry were combined, regardless of the tumor morphology: sensitivity, 88%; specificity, 64%; area under the receiver-operating characteristic (AUC) curve, 0.83. Combinations of tumor morphology with p16(INK4a) immunohistochemistry or with HR-HPV ISH performed similarly well. CONCLUSIONS In penile SCC, both p16(INK4a) immunohistochemistry and ISH for HR-HPV increase the predictive ability of routine morphology in defining HPV status. These tests can be interpreted differentially, depending on the necessity of a higher sensitivity or a higher specificity. For research/screening studies, we recommend combining tumor morphology, p16(INK4a) immunohistochemistry, and HR-HPV ISH. To increase sensitivity, positivity in any of these predictors should be considered as indicative of HPV infection. For routine diagnosis of clinical cases, criteria should be more stringent, and, to achieve the highest specificity in classifying a case as HPV-related, all predictors should be consistently positive. The data generated in the present study could be used in algorithms for defining HPV status in penile carcinomas.

Abstract
Human papillomaviruses (HPVs) are the cause of cervical cancer and possibly a subset of squamous cell carcinomas (SCCs) in other sites. However, the prevalence and distribution of HPV subtypes remain unclear. In the present study, we collected and analyzed 511 paraffin sections of non-cervical SCC from patients in Qingdao, China, for the presence of HPV using polymerase chain reaction (PCR). We identified that 55.77% (285/511) of the samples were positive for HPV infection. There was a significant association between HPV type and the different sites of SCC. An association between HPV-positive cases and tobacco, alcohol, age and tumor differentiation was demonstrated. The information provided by this study may be important for further investigation into the association between HPV and SCC. High-risk HPV subtypes were associated with the malignant degree of SCC. This study provided a theoretical basis for the preventative treatment of non-cervical SCC using HPV vaccines.

Abstract
Cervical carcinoma is the most common malignant tumor among woman in Paraguay. Cytological screening programs have not been successful and a plan for human papillomavirus (HPV) based-screening program and/or vaccination is under evaluation. This study aimed to identify the contribution of HPV genotypes in invasive cervical cancer in Paraguay to provide essential background data to guide and assess the introduction and impact of new preventive strategies based on HPV. Four hundred thirty two histologically confirmed cases (1960-2004) were analyzed. HPV detection in paraffin blocks was performed at the Catalan Institute of Oncology using PCR with SPF-10 broad spectrum primers followed by DNA enzyme immunoassay and genotyping with a reverse hybridization line probe analysis. The majority of cases were squamous cell carcinoma (92.8%). Mean patients age was 48 years old. HPV DNA was detected in 73.1% of the cases and single infections were predominant (97.8%). The most common HPV single types were 16, 18, 45, 33, 31, 52, 35, and 39. 73.1% of HPV positive cases had an HPV 16, 18 as single infection. HPV16 was frequent in SCC whereas HPV 18 and 45 were prevalent in glandular tumors. Significant decrease of HPV 16 with age groups (P-trend = 0.022) and increase in other HPV types (P-trend > 0.001) were observed. The potential impact of HPV 16 and 18 for a vaccination program was 73.1%. The study provide a profile of the HPV situation in the country, with robust clinical, pathological and virological data which would permit a better cervical cancer screening and vaccination programs.
