RESUMEN
Human papillomavirus (HPV)-independent vulvar squamous cell carcinomas (VSCC) and its precursors frequently harbour TP53 mutations. Recently, six p53 immunohistochemical (IHC) patterns have been defined, which have shown strong correlation with TP53 mutation status. However, few studies have applied this new six-pattern framework and none of them exhaustively compared p53 IHC positivity and patterns between invasive VSCC and adjacent skin lesion. We performed p53 IHC in a series of 779 HPV-independent VSCC with adjacent skin and evaluated the IHC slides following the newly described classification. Some 74.1% invasive VSCC showed abnormal p53 IHC staining. A skin lesion was identified in 450 cases (57.8%), including 254 intraepithelial precursors and 196 inflammatory/reactive lesions. Two hundred and ten of 450 (47%) VSCC with associated skin lesions showed an abnormal p53 IHC stain, with an identical staining pattern between the VSCC and the adjacent skin lesion in 80% of the cases. A total of 144/450 (32%) VSCC showed wild-type p53 IHC both in the invasive VSCC and adjacent skin lesion. Finally, 96/450 (21%) VSCC showed p53 IHC abnormal staining in the invasive VSCC but a wild-type p53 staining in the skin lesion. Most of the discordant cases (70/96; 73%) showed adjacent inflammatory lesions. In conclusion, the p53 IHC staining and pattern are usually identical in the VSCC and the intraepithelial precursor.

There are at least two different etio-pathogenic pathways for the development of vulvar squamous cell carcinoma (VSCC): one associated with infection by human papillomavirus (HPV) and another independent of HPV. We aimed to describe the histological characteristics of HPV-associated and -independent tumors and to determine the best strategy to identify HPV in VSCC. A single paraffin block was available for review from a series of 1,594 VSCCs. In all cases HPV DNA detection was analyzed using the SPF10PCR/DEIA/LiPA25 system and p16 immunohistochemistry (IHC). A tumor was considered as unquestionably HPV-associated if both HPV DNA and p16 IHC were positive. A tumor was considered indisputably HPV-independent if both HPV DNA and p16 IHC were negative. Two groups of tumors were classified as non-conclusive: (1) HPV DNA+/p16- and (2) HPV DNA-/p16+. WHO typing and a thorough histological evaluation were conducted in all cases. Four hundred and forty-one tumors were HPV DNA+ with 367 cases (23.0%) being HPV DNA+/p16+. The latter tumors were more frequently basaloid or warty (49.8%), but 36.5% were of the keratinizing type; 1,153 tumors were HPV DNA-, with 1,060 cases (66.5%) being HPV DNA-/p16-. These HPV DNA-/p16- tumors were mostly keratinizing (81.2%) but were occasionally basaloid or warty (5.2%). The features of HPV DNA-/p16+ cases (n = 93) were similar to those of the HPV-associated VSCC, and HPV DNA+/p16- (n = 74) cases had a more diverse profile, although they were more similar to HPV-independent tumors. Several histological characteristics were more frequently associated with HPV-related VSCC (koilocytotic-like change, necrosis, moderate to marked pleomorphism, invasive front in nests; p < 0.001), however, none of these characteristics allowed differentiation between HPV-associated and -independent VSCC. In conclusion, histological criteria do not allow differentiation between HPV-associated and -independent VSCC. p16 Alone is a clinically easy strategy to determine HPV status in VSCC.

The carcinogenic role of high-risk human papillomavirus (HR-HPV) types in the increasing subset of vulvar intraepithelial neoplasia and vulvar cancer in young women has been established. However, the actual number of vulvar cancer cases attributed to HPV is still imprecisely defined. In an attempt to provide a more precise definition of HPV-driven vulvar cancer, we performed HPV-type-specific E6*I mRNA analyses available for 20 HR-/possible HR (pHR)-HPV types, on tissue samples from 447 cases of vulvar cancer. HPV DNA genotyping was performed using SPF10-LiPA25 assay due to its high sensitivity in formalin-fixed paraffin-embedded tissues. Data on p16INK4a expression was available for comparative analysis via kappa statistics. The use of highly sensitive assays covering the detection of HPV mRNA in a broad spectrum of mucosal HPV types resulted in the detection of viral transcripts in 87% of HPV DNA+ vulvar cancers. Overall concordance between HPV mRNA+ and p16INK4a upregulation (strong, diffuse immunostaining in >25% of tumor cells) was 92% (K=0.625, 95% confidence interval (CI)=0.531-0.719). Among these cases, 83% were concordant pairs of HPV mRNA+ and p16INK4a+ and 9% were concordant pairs of HPV mRNA- and p16INK4a-. Our data confirm the biological role of HR-/pHR-HPV types in the great majority of HPV DNA+ vulvar cancers, resulting in an HPV-attributable fraction of at least 21% worldwide. Most HPV DNA+ vulvar cancers were associated with HPV16 (85%), but a causative role for other, less frequently occurring mucosal HPV types (HPV26, 66, 67, 68, 70 and 73) was also confirmed at the mRNA level for the first time. These findings should be taken into consideration for future screening options as HPV-associated vulvar preneoplastic lesions have increased in incidence in younger women and require different treatment than vulvar lesions that develop from rare autoimmune-related mechanisms in older women.

Eight HPV types (HPV26, 53, 66, 67, 68, 70, 73 and 82) that are phylogenetically closely related to 12 WHO-defined high-risk (HR) HPV have been rarely but consistently identified as single HPV infections in about 3% of cervical cancer (CxCa) tissues. Due to lack of biological data, these types are referred to as probable/possible (p) HR-HPV. To analyse their biological activity in direct comparison to HR-HPV types, we selected 55 formalin-fixed, paraffin-embedded (FFPE) CxCa tissues harbouring single pHR-HPV infections (2-13 cases per type) and 266 tissues harbouring single HR-HPV (7-40 cases per type) from a worldwide, retrospective, cross-sectional study. Single HPV infection was verified by two genotyping methods. Presence of type-specific spliced E6*I mRNA transcripts and expression of cellular proteins indicative of HPV transformation were assessed in all cases. In 55 CxCa tissues with pHR-HPV, E6*I mRNA expression was 100%; high p16(INK4a) , 98%; low pRb, 96%; low CyD1, 93%; and low p53, 84%. Compared to HPV16 tissues as a reference, individual frequencies of these five markers did not differ significantly, either for any of the eight pHR-HPV and the 11 other HR types individually or for the groups of pHR and HR types without HPV16. We conclude that the eight pHR-HPV types, when present as a single infection in CxCa, are biologically active and affect the same cellular pathways as any of the fully recognized carcinogenic HR-HPV types. Therefore we have provided molecular evidence of carcinogenicity for types currently classified as probably/possibly carcinogenic. Although this evidence is crucial for HPV-type carcinogenicity classification, per se it is not sufficient for inclusion of these HPV types into population-wide primary and secondary prevention programmes. Such decisions have to include careful estimation of effectiveness and cost-benefit analyses.

The goal of our study was to provide comprehensive data on the worldwide human papillomavirus (HPV) genotype distribution in patients with invasive cervical adenocarcinoma in correlation with histologic tumor subtypes, geographical location, patients' age, and duration of sample storage. Paraffin-embedded samples of 760 cervical adenocarcinoma cases were collected worldwide. A three-level pathology review of cases was performed to obtain consensus histologic diagnoses and 682 cases were determined to be eligible for further analysis. HPV DNA detection and genotyping was performed using SPF-10/DEIA/LiPA(25) system (version 1). Classic cervical adenocarcinoma accounted for 83.1% of cases, while rare histological variants accounted for a few percent of cases individually. HPV positivity varied significantly between the different histologic tumor subtypes. Classic cervical adenocarcinoma showed high HPV positivity (71.8%), while other adenocarcinoma types had significantly lower HPV prevalence (endometrioid 27.3%, serous 25%, clear cell 20%, not otherwise specified 13.9%, and minimal deviation 8.3%). In all, 91.8% of HPV-positive tumors showed the presence of a single viral type and in 7% of cases multiple viral types were detected. Three HPV genotypes, HPV 16, 18, and 45, dominated in all adenocarcinomas and together accounted for 94.1% of HPV-positive tumors. HPV16 was the most common and found in 50.9% of HPV-positive cases, followed by HPV18 (31.6%) and HPV45 (11.6%). HPV prevalence varied depending on geographical region, patient age, and sample storage time. Tumors from older patients and tumor samples with longer storage time showed lower HPV prevalence. Our results indicate that HPV vaccines may prevent up to 82.5% (HPV16/18) and up to 95.3% (9-valent vaccine) of HPV-positive cervical adenocarcinomas, mostly the classic type. HPV testing and vaccination will not provide full coverage for a very small subset of classical adenocarcinomas and most of the rare tumor variants such as clear cell, serous, endometrioid, and minimal deviation.

BACKGROUND: Poor attendance to cervical cancer (CC) screening is a major risk factor for CC. Efforts to capture underscreened women are considerable and once women agree to participate, the provision of longitudinal validity of the screening test is of paramount relevance. We evaluate the addition of high risk HPV test (HPV) to cervical cytology as a primary screening test among underscreened women in the longitudinal prediction of intraepithelial lesions grade 2 or worse (CIN2+). METHODS: Women were included in the study if they were older than 39 years and with no evidence of cervical cytology in the previous five years within the Public Primary Health Care System in Catalonia (Spain). 1,832 underscreened women from eight public primary health areas were identified during 2007-2008 and followed-up for over three years to estimate longitudinal detection of CIN2+. Accuracy of each screening test and the combination of both to detect CIN2+ was estimated. The risk of developing CIN2+ lesions according to histology data by cytology and HPV test results at baseline was estimated using the Kaplan-Meier method. RESULTS: At baseline, 6.7% of participants were HPV positive, 2.2% had an abnormal cytology and 1.3% had both tests positive. At the end of follow-up, 18 out of 767 (2.3%) underscreened women had a CIN2+, two of which were invasive CC. The three-year longitudinal sensitivity and specificity estimates to detect CIN2+ were 90.5% and 93.0% for HPV test and 38.2% and 97.8% for cytology. The negative predictive value was >99.0% for each test. No additional gains in validity parameters of HPV test were observed when adding cytology as co-test. The referral to colposcopy was higher for HPV but generated 53% higher detection of CIN2+ compared to cytology. CONCLUSIONS: Underscreened women had high burden of cervical disease. Primary HPV screening followed by cytology triage could be the optimal strategy to identify CIN2+ leading to longer and safe screen intervals.

OBJECTIVE: Human papillomavirus (HPV) genotype distribution in invasive cervical cancer (ICC) is critical to guide the introduction and to assess the impact of HPV prophylactic vaccines. This study aims to provide specific information for Spain. METHODS: 1043 histological confirmed ICC cases diagnosed from 1940 to 2007 from six Spanish regions were assembled. HPV DNA detection was performed by SPF(10) broad-spectrum PCR followed by deoxyribonucleic acid enzyme immunoassay and genotyping by reverse hybridization line probe assay (LiPA(25)) (version 1). RESULTS: Of 1043 ICC cases, 904 were HPV DNA positive (adjusted prevalence: 89.1%). The eight most common types, in decreasing order, were HPV 16, 18, 33, 31, 45, 35, 52 and 56, accounting for more than 90% of cases. HPV 16 and 18 contributed to 72.4% of all HPV positive ICC cases. In cervical adenocarcinomas, this contribution increased up to 94%. HPV 16 and 18 relative contributions showed a stable pattern over the 60 year study period. HPV 45, 18 and 16-positive ICC cases presented at younger ages than cases with other HPV types (adjusted mean age: 43.8, 45.2, 52.6 and 57.7 years, respectively). CONCLUSIONS: HPV 16 and 18 accounted together for a 72.4% of positive cases, with no statistically significant changes in their relative contributions over the last decades. In 94% of cervical adenocarcinomas we identified at least one of the two HPV types included in the current vaccines (HPV 16/18). Results suggest a major impact of HPV vaccines on reduction of ICC burden in Spain in the HPV vaccinated cohorts.

BACKGROUND: A protocol for cervical cancer screening among sexually active women 25 to 65 years of age was introduced in 2006 in Catalonia, Spain to increase coverage and to recommend a 3-year-interval between screening cytology. In addition, Human Papillomavirus (HPV) was offered as a triage test for women with a diagnosis of atypical squamous cells of undetermined significance (ASC-US). HPV testing was recommended within 3 months of ASC-US diagnosis. According to protocol, HPV negative women were referred to regular screening including a cytological exam every 3 years while HPV positive women were referred to colposcopy and closer follow-up. We evaluated the implementation of the protocol and the prediction of HPV testing as a triage tool for cervical intraepithelial lesions grade two or worse (CIN2+) in women with a cytological diagnosis of ASC-US. METHODS: During 2007-08 a total of 611 women from five reference laboratories in Catalonia with a novel diagnosis of ASC-US were referred for high risk HPV (hrHPV) triage using high risk Hybrid Capture version 2. Using routine record linkage data, women were followed for 3 years to evaluate hrHPV testing efficacy for predicting CIN2+ cases. Logistic regression analysis was used to estimate the odds ratio for CIN2 +. RESULTS: Among the 611 women diagnosed with ASC-US, 493 (80.7%) had at least one follow-up visit during the study period. hrHPV was detected in 48.3% of the women at study entry (mean age 35.2 years). hrHPV positivity decreased with increasing age from 72.6% among women younger than 25 years to 31.6% in women older than 54 years (p < 0.01). At the end of the 3 years follow-up period, 37 women with a diagnosis of CIN2+ (18 CIN2, 16 CIN3, 2 cancers, and 1 with high squamous intraepithelial lesions--HSIL) were identified and all but one had a hrHPV positive test at study entry. Sensitivity to detect CIN2+ of hrHPV was 97.2% (95%confidence interval (CI) = 85.5-99.9) and specificity was 68.3% (95%CI = 63.1-73.2). The odds ratio for CIN2+ was 45.3 (95% CI: 6.2-333.0), when among ASC-US hrHPV positive women were compared to ASC-US hrHPV negative women. CONCLUSIONS: Triage of ASC-US with hrHPV testing showed a high sensitivity for the detection of CIN2+ and a high negative predictive value after 3 years of follow-up. The results of this study are in line with the current guidelines for triage of women with ASC-US in the target age range of 25-65. Non adherence to guidelines will lead to unnecessary medical interventions. Further investigation is needed to improve specificity of ASC-US triage.

Background: Tests or test algorithms for diagnosing HPV-driven oral cavity and laryngeal head and neck carcinomas (HNC) have not been yet validated, and the differences among oral cavity and laryngeal sites have not been comprehensively evaluated. We aimed to assess the utility of a diagnostic algorithm for the detection of HPV-driven oral cavity (OCC), oropharyngeal (OPC) and laryngeal (LC) carcinomas using HPV-DNA testing followed by p16INK4a immunohistochemistry, taking E6*I mRNA detection as the reference standard. Methods: Formalin-fixed paraffin-embedded OCC, OPC, and LC carcinomas were collected from pathology archives in 29 countries. All samples were subjected to histopathological evaluation, DNA quality control, and HPV-DNA detection. All HPV-DNA-positive samples (including 78 OCC, 257 OPC, and 51 LC out of 3680 HNC with valid HPV-DNA results) were also tested for p16INK4a immunohistochemistry and E6*I mRNA. Three different cutoffs of nuclear and cytoplasmic staining were evaluated for p16INK4a: (a) >25%, (b) >50%, and (c) ≥70%. The concordance of p16INK4a and E6*I mRNA among HPV-DNA-positive OCC, OPC, and LC cases was assessed. Results: A total of 78 OCC, 257 OPC, and 51 LC were HPV-DNA-positive and further tested for p16INK4a and E6*I mRNA. The percentage of concordance between p16INK4a (cutoff ≥ 70%) and E6*I mRNA among HPV-DNA-positive OCC, OPC, and LC cases was 79.5% (95% CI 69.9−89.1%), 82.1% (95% CI 77.2−87.0%), and 56.9% (95% CI 42.3−71.4%), respectively. A p16INK4a cutoff of >50% improved the concordance although the improvement was not statistically significant. For most anatomical locations and p16INK4a cutoffs, the percentage of discordant cases was higher for HPV16- than HPV-non16-positive cases. Conclusions: The diagnostic algorithm of HPV-DNA testing followed by p16INK4a immunohistochemistry might be helpful in the diagnosis of HPV-driven OCC and OPC, but not LC. A different p16INK4a expression pattern was observed in those cases HPV-DNA-positive for types other than HPV16, as compared to HPV16-positive cases. Our study provides new insights into the use HPV-DNA, p16INK4a, and HPV-E6*I mRNA for diagnosing an HPV-driven HNC, including the optimal HPV test or p16INK4a cutoffs to be used. More studies are warranted to clarify the role of p16INK4a and HPV status in both OPC and non-OPC HNC.
RESUMEN
BACKGROUND: Knowledge about the distribution of human papillomavirus (HPV) genotypes in invasive cervical cancer is crucial to guide the introduction of prophylactic vaccines. We aimed to provide novel and comprehensive data about the worldwide genotype distribution in patients with invasive cervical cancer. METHODS: Paraffin-embedded samples of histologically confirmed cases of invasive cervical cancer were collected from 38 countries in Europe, North America, central South America, Africa, Asia, and Oceania. Inclusion criteria were a pathological confirmation of a primary invasive cervical cancer of epithelial origin in the tissue sample selected for analysis of HPV DNA, and information about the year of diagnosis. HPV detection was done by use of PCR with SPF-10 broad-spectrum primers followed by DNA enzyme immunoassay and genotyping with a reverse hybridisation line probe assay. Sequence analysis was done to characterise HPV-positive samples with unknown HPV types. Data analyses included algorithms of multiple infections to estimate type-specific relative contributions. FINDINGS: 22,661 paraffin-embedded samples were obtained from 14,249 women. 10,575 cases of invasive cervical cancer were included in the study, and 8977 (85%) of these were positive for HPV DNA. The most common HPV types were 16, 18, 31, 33, 35, 45, 52, and 58 with a combined worldwide relative contribution of 8196 of 8977 (91%, 95% CI 90-92). HPV types 16 and 18 were detected in 6357 of 8977 of cases (71%, 70-72) of invasive cervical cancer. HPV types 16, 18, and 45 were detected in 443 of 470 cases (94%, 92-96) of cervical adenocarcinomas. Unknown HPV types that were identified with sequence analysis were 26, 30, 61, 67, 69, 82, and 91 in 103 (1%) of 8977 cases of invasive cervical cancer. Women with invasive cervical cancers related to HPV types 16, 18, or 45 presented at a younger mean age than did those with other HPV types (50·0 years [49·6-50·4], 48·2 years [47·3-49·2], 46·8 years [46·6-48·1], and 55·5 years [54·9-56·1], respectively). INTERPRETATION: To our knowledge, this study is the largest assessment of HPV genotypes to date. HPV types 16, 18, 31, 33, 35, 45, 52, and 58 should be given priority when the cross-protective effects of current vaccines are assessed, and for formulation of recommendations for the use of second-generation polyvalent HPV vaccines. Our results also suggest that type-specific high-risk HPV-DNA-based screening tests and protocols should focus on HPV types 16, 18, and 45.

Two etiopathogenic types of vulvar squamous cell carcinoma (VSCC) have been described: human papillomavirus (HPV)-associated and HPV-independent. Precursor lesions, frequently identified in the adjacent skin, are also distinct in the 2 types of VSCC: high-grade squamous intraepithelial lesions (HSILs) in HPV-associated VSCC and differentiated vulvar intraepithelial neoplasia (dVIN) or vulvar acanthosis with altered differentiation in HPV-independent VSCC. Although HPV-independent precursors mimicking HSIL have been described in the vulva, their frequency and morphologic spectrum have not been completely characterized. We explored, in a large series of HPV-independent VSSC, the frequency and the histologic features of precursors mimicking HSIL. We included 779 DNA HPV-negative/p16-negative VSCC with at least 1 cm of adjacent skin. We evaluated the histologic and immunohistochemical (p16 and p53) characteristics of the intraepithelial lesions, focusing on precursors mimicking HPV-associated vulvar HSIL. A total of 254 tumors (33%) had adjacent premalignant lesions. Of them, 186 (73%) had dVIN, 22 (9%) had vulvar acanthosis with altered differentiation, and 46 (18%) had lesions that mimicked HSIL. The mean age of the patients with these HSIL-like lesions was 72±15 years. Twenty-six of these HSIL-like lesions had basaloid morphology, 13 warty, and 7 mixed basaloid/warty features. All the HSIL-like precursors were DNA HPV-negative/p16-negative; 74% of them showed p53 abnormal staining and 35% of them had areas of conventional dVIN. In conclusion, about one fifth of the HPV-independent precursors mimic HSIL, showing either basaloid or warty features. Older age and the presence of areas of typical HPV-independent intraepithelial lesions, together with p16 negativity, should raise suspicion of an HPV-independent etiology.

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.

Background: Anti-epidermal-growth-factor-receptor (EGFR) therapies in combination with radiotherapy are being studied on de-escalation clinical trials for HPV-related oropharyngeal cancer (OPC) patients. The HPV16-E5 oncoprotein increases recycling of activated EGFR to the cell surface, enhancing factor signal transduction. Our aim was to evaluate viral HPV16-E5 oncogene expression as well as EGFR and phosphorylated-EGFR (pEGFR), protein levels as biomarkers for clinical outcome in a retrospective cohort of OPC patients. Methods: Formalin-fixed-paraffin-embedded OPCs were collected from 1990 to 2013. OPC samples containing HPV-DNA were subject to viral E6 * I mRNA detection and p16INK4a immunohistochemistry (IHC). HPV16-positive cases were evaluated for HPV16-E5 (RT-PCR) and EGFR/pEGFR (IHC). A stratified and matched random sample of HPV-negative samples was used as control and evaluated for EGFR/pEGFR. Overall survival (OS) and disease free survival (DFS) estimates were assessed for locally advanced OPC patients (stage III, IVa,b 7th edition). Results: Among 788 OPC patient samples, 53 were double positive for HPV16-DNA/p16INK4a. HPV16-E5 expression was found in 41 of 53 samples (77.4%). EGFR expression was observed in 37.7 vs 70.8% of HPV16-positive vs HPV-negative samples, respectively; (adjusted OR = 0.15) 5% CI = 0.04-0.56]). Expression of pEGFR followed an inverse pattern with 39.6 and 24.9% detection in HPV16-positive and HPV-negative samples; (adjusted OR = 1.58 [95% CI = 0.48-5.17]). Within HPV16-positive cases, no association between HPV16-E5/EGFR nor pEGFR was observed. With a median follow-up of 39.36 months (min = 0.03 - max = 272.07), the combination of HPV status and EGFR or pEGFR expression were predictors of better OS (p < 0.001, for both) and DFS (p < 0.001 for EGFR and p = 0.003 for pEGFR). Conclusions: HPV16-E5 is highly expressed on HPV16-positive OPCs. Interestingly, HPV16-positive cases expressed significantly more pEGFR while HPV-negative cases expressed more EGFR. The combinations of HPV status and EGFR or pEGFR may be useful biomarkers for evaluating prognosis outcome in OPC patients.
RESUMEN
AIMS: Neuroendocrine tumors (NET) of the cervix are rare tumors with a very aggressive course. The human papillomavirus (HPV) has been linked to its etiology. The objective of this study is to describe HPV prevalence and genotype distribution of NET. METHODS AND RESULTS: Forty-nine tumors with histological neuroendocrine features were identified among 10,575 invasive cervical cancer (ICC) cases from an international study. HPV DNA detection was done using SPF10/DEIA /LiPA25 system. Immunohistochemical (IHC) staining for neuroendocrine markers (chromogranin A, synaptophysin, CD56) and for p16INK4a as a surrogate for HPV transforming infection was performed. In 13 samples with negative IHC for all 3 neuroendocrine markers studied, it was possible to conduct electron microscopy (EM). NET represented 0.5% of the total ICC series and HPV was detected in 42 out of 49 samples (85.7%, 95%CI:72.8%,94.1%). HPV16 was the predominant type (54.8%), followed by HPV18 (40.5%). p16INK4a overexpression was observed in 38/44 cases (86.4%). Neuroendocrine IHC markers could be demonstrated in 24/37 (64.9%) cases. EM identified neuroendocrine granules in 8 samples with negative IHC markers. CONCLUSIONS: Our data confirms the association of cervical NET with HPV and p16INK4a overexpression. Specifically, HPV16 and 18 accounted together for over 95% of the HPV positive cases. Current HPV vaccines could largely prevent these aggressive tumors.

BACKGROUND: Many countries, mainly high- and upper-middle income, have implemented human papillomavirus (HPV) vaccination programs, with 47 million women receiving the full course of vaccine (three doses) in 2014. To evaluate the potential impact of HPV vaccines in the reduction of HPV-related disease, we aimed to estimate the HPV type distribution and burden of anogenital and head and neck cancers attributable to HPV types (HPVs 16/18/31/33/45/52/58/6/11) included in currently licensed HPV vaccines. METHODS: In all, 18 247 formalin-fixed paraffin-embedded specimens were retrieved from 50 countries. HPV DNA detection and typing were performed with the SPF-10 PCR/DEIA/LiPA25 system. With the exception of cervical cancer, HPV DNA-positive samples were additionally subjected to HPV E6*I mRNA detection and/or p16INK4a immunohistochemistry. For cervical cancer, estimates were based on HPV DNA, whereas for other sites, estimates were based on HPV DNA, E6*I mRNA, and p16INK4a biomarkers. RESULTS: The addition of HPVs 31/33/45/52/58 to HPVs 16/18/6/11 in the nonavalent HPV vaccine could prevent almost 90% of cervical cancer cases worldwide. For other sites, the nonavalent HPV vaccine could prevent 22.8% of vulvar, 24.5% of penile, 60.7% of vaginal, 79.0% of anal cancers, 21.3% of oropharyngeal, 4.0% of oral cavity, and 2.7% of laryngeal cancer cases. CONCLUSIONS: Our estimations suggest a potential impact of the nonavalent HPV vaccine in reducing around 90% of cervical cancer cases and a global reduction of 50% of all the cases at HPV-related cancer sites.
RESUMEN
BACKGROUND: The etiologic role of human papillomaviruses (HPV) in oropharyngeal cancer (OPC) is well established. Nevertheless, information on survival differences by anatomic sub-site or treatment remains scarce, and it is still unclear the HPV-relatedness definition with best diagnostic accuracy and prognostic value. METHODS: We conducted a retrospective cohort study of all patients diagnosed with a primary OPC in four Catalonian hospitals from 1990 to 2013. Formalin-fixed, paraffin-embedded cancer tissues were subjected to histopathological evaluation, DNA quality control, HPV-DNA detection, and p16INK4a/pRb/p53/Cyclin-D1 immunohistochemistry. HPV-DNA positive and a random sample of HPV-DNA negative cases were subjected to HPV-E6*I mRNA detection. Demographic, tobacco/alcohol use, clinical and follow-up data were collected. Multivariate models were used to evaluate factors associated with HPV positivity as defined by four different HPV-relatedness definitions. Proportional-hazards models were used to compare the risk of death and recurrence among HPV-related and non-related OPC. RESULTS: 788 patients yielded a valid HPV-DNA result. The percentage of positive cases was 10.9%, 10.2%, 8.5% and 7.4% for p16INK4a, HPV-DNA, HPV-DNA/HPV-E6*I mRNA, and HPV-DNA/p16INK4a, respectively. Being non-smoker or non-drinker was consistently associated across HPV-relatedness definitions with HPV positivity. A suggestion of survival differences between anatomic sub-sites and treatments was observed. Double positivity for HPV-DNA/p16INK4a showed strongest diagnostic accuracy and prognostic value. CONCLUSIONS: Double positivity for HPV-DNA/p16INK4a, a test that can be easily implemented in the clinical practice, has optimal diagnostic accuracy and prognostic value. Our results have strong clinical implications for patients' classification and handling and also suggest that not all the HPV-related OPC behave similarly.

BACKGROUND: Invasive penile cancer is a rare disease with an approximately 22 000 cases per year. The incidence is higher in less developed countries, where penile cancer can account for up to 10% of cancers among men in some parts of Africa, South America, and Asia. OBJECTIVE: To describe the human papillomavirus (HPV) DNA prevalence, HPV type distribution, and detection of markers of viral activity (ie, E6*I mRNA and p16(INK4a)) in a series of invasive penile cancers and penile high-grade squamous intraepithelial lesions (HGSILs) from 25 countries. A total of 85 penile HGSILs and 1010 penile invasive cancers diagnosed from 1983 to 2011 were included. DESIGN, SETTING, AND PARTICIPANTS: After histopathologic evaluation of formalin-fixed paraffin-embedded samples, HPV DNA detection and genotyping were performed using the SPF-10/DEIA/LiPA25 system, v.1 (Laboratory Biomedical Products, Rijswijk, The Netherlands). HPV DNA-positive cases were additionally tested for oncogene E6*I mRNA and all cases for p16(INK4a) expression, a surrogate marker of oncogenic HPV activity. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: HPV DNA prevalence and type distributions were estimated. RESULTS AND LIMITATIONS: HPV DNA was detected in 33.1% of penile cancers (95% confidence interval [CI], 30.2-36.1) and in 87.1% of HGSILs (95% CI, 78.0-93.4). The warty-basaloid histologic subtype showed the highest HPV DNA prevalence. Among cancers, statistically significant differences in prevalence were observed only by geographic region and not by period or by age at diagnosis. HPV16 was the most frequent HPV type detected in both HPV-positive cancers (68.7%) and HGSILs (79.6%). HPV6 was the second most common type in invasive cancers (3.7%). The p16(INK4a) upregulation and mRNA detection in addition to HPV DNA positivity were observed in 69.3% of HGSILs, and at least one of these HPV activity markers was detected in 85.3% of cases. In penile cancers, these figures were 22.0% and 27.1%, respectively. CONCLUSIONS: About a third to a fourth of penile cancers were related to HPV when considering HPV DNA detection alone or adding an HPV activity marker, respectively. The observed HPV type distribution reinforces the potential benefit of current and new HPV vaccines in the reduction of HPV-related penile neoplastic lesions. PATIENT SUMMARY: About one-third to one-quarter of penile cancers were related to human papillomavirus (HPV). The observed HPV type distribution reinforces the potential benefit of current and new HPV vaccines to prevent HPV-related penile neoplastic lesions.

BACKGROUND: We conducted a large international study to estimate fractions of head and neck cancers (HNCs) attributable to human papillomavirus (HPV-AFs) using six HPV-related biomarkers of viral detection, transcription, and cellular transformation. METHODS: Formalin-fixed, paraffin-embedded cancer tissues of the oral cavity (OC), pharynx, and larynx were collected from pathology archives in 29 countries. All samples were subject to histopathological evaluation, DNA quality control, and HPV-DNA detection. Samples containing HPV-DNA were further subject to HPV E6*I mRNA detection and to p16(INK4a), pRb, p53, and Cyclin D1 immunohistochemistry. Final estimates of HPV-AFs were based on HPV-DNA, HPV E6*I mRNA, and/or p16(INK4a) results. RESULTS: A total of 3680 samples yielded valid results: 1374 pharyngeal, 1264 OC, and 1042 laryngeal cancers. HPV-AF estimates based on positivity for HPV-DNA, and for either HPV E6*I mRNA or p16(INK4a), were 22.4%, 4.4%, and 3.5% for cancers of the oropharynx, OC, and larynx, respectively, and 18.5%, 3.0%, and 1.5% when requiring simultaneous positivity for all three markers. HPV16 was largely the most common type. Estimates of HPV-AF in the oropharynx were highest in South America, Central and Eastern Europe, and Northern Europe, and lowest in Southern Europe. Women showed higher HPV-AFs than men for cancers of the oropharynx in Europe and for the larynx in Central-South America. CONCLUSIONS: HPV contribution to HNCs is substantial but highly heterogeneous by cancer site, region, and sex. This study, the largest exploring HPV attribution in HNCs, confirms the important role of HPVs in oropharyngeal cancer and drastically downplays the previously reported involvement of HPVs in the other HNCs.

OBJECTIVE: Audit of women with invasive cervical cancer (CC) is critical for quality control within screening activities. We analysed the screening history in the 10 years preceding the study entry in women with and without CC during 2000-2011. METHODS: 323 women with CC from six pathology departments in Catalonia (Spain) and 23,782 women with negative cytology were compared. Age, previous history of cytologies, and histological type and FIGO stage were collected from the pathology registries. Logistic regression analysis was used to estimate odds ratios (OR) and 95% confidence intervals (CI95%). RESULTS: History of cytology was registered in 26.2% of CC cases and in 78% of the control women (P < 0.0001) and its frequency decreased with increasing age. Compared to women with squamous cell carcinoma, adenocarcinoma cases were significantly more likely to have a cytology within the 3-year interval preceding cancer diagnosis (OR = 2.6 CI 95%: 1.2-5.6) and to have normal cytology results in previous screenings (OR = 2.4 CI 95%: 1.2-4.5). FIGO II-IV cases were more common among older women (older than 60 years). CONCLUSIONS: Absence of prior screening history was extremely common among CC cases compared to controls. Organized actions to reduce underscreened women and use of highly sensitive HPV-based tests could be important to reduce CC burden.

Introducción: Durante el ciclo de vida de los individuos son imprescindibles intervenciones para detectar y reducir el riesgo y las complicaciones de las enfermedades crónicas. Objetivo: Determinar la prevalencia de valores de riesgo vascular de los principales indicadores del metabolismo glucídico y lipídico en adolescentes y ancianos de La Habana. Métodos: Se realizó un estudio transversal en una muestra conformada por adolescentes (469 de 12-16 años) aparentemente sanos y ancianos (395 de 65-100 años) sin diagnóstico de enfermedades asociadas a la alteración marcada del estado nutricional y metabólico. Ambas poblaciones fueron evaluadas para glucosa, triglicéridos, colesterol total, colesterol de lipoproteinas de alta densidad y colesterol de lipoproteínas de baja densidad, séricos, mediante métodos enzimáticos convencionales. Se usaron rangos de riesgo referentes. Los resultados se analizaron mediante estadística descriptiva. Resultados: En los adolescentes evaluados, los triglicéridos (35,6 por ciento) y el colesterol total (23,9 por ciento) mostraron las mayores frecuencias de valores de riesgo. En las hembras ambos marcadores se mantuvieron como los más elevados en ese orden, mientras que, en los varones, la glucosa (25,5 por ciento) secundó a los triglicéridos como indicadores más alterados. En ancianos, al colesterol de lipoproteínas de baja densidad (58,2 por ciento) y al colesterol total (48,6 por ciento) correspondieron las mayores frecuencias de cifras de riesgo, patrón que se repitió en cada sexo. Los valores promedio de los indicadores fueron marcadamente superiores en ancianos que, en adolescentes, excepto para glucosa y colesterol de lipoproteínas de alta densidad. Conclusiones: Los resultados obtenidos muestran una elevada prevalencia de valores de riesgo vascular de varios indicadores metabólicos evaluados en adolescentes y ancianos, lo que sugiere la necesidad de monitorear los indicadores analizados e implementar intervenciones modificadoras de sus valores hacia la reducción del riesgo asociado, desde etapas tempranas, como las previas a la adolescencia(AU)
Introduction: During the life cycle of individuals, interventions are essential to detect and reduce the risk and complications of chronic diseases. Objective: To determine the prevalence of vascular risk values of the main indicators of carbohydrate and lipid metabolism in adolescents and elderlies in Havana. Methods: A cross-sectional study was carried out with a sample made up of apparently healthy adolescents (469; aged 12-16 years) and elderlies (395 aged 65-100 years) without a diagnosis of diseases associated with marked alteration of nutritional and metabolic status. Both populations were evaluated regarding serum glucose, triglycerides, total cholesterol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol using conventional enzymatic methods. Reference risk ranges were used. The results were analyzed using descriptive statistics. Results: In the evaluated adolescents, triglycerides (35.6 percent) and total cholesterol (23.9 percent) showed the highest frequencies of risk values. In females, both markers remained the highest in that aspect; while in males, glucose (25.5 percent) accounted second after triglycerides as the most altered indicators. In the elderlies, low-density lipoprotein cholesterol (58.2 percent) and total cholesterol (48.6 percent) corresponded to the highest frequencies of risk values, a pattern that was repeated in each sex. The average values of the indicators were markedly higher in the elderlies than in adolescents, except for glucose and high-density lipoprotein cholesterol. Conclusions: The results obtained show high prevalence of vascular risk values of several metabolic indicators evaluated in adolescents and elderlies, which suggests the need to monitor the analyzed indicators and implement interventions to modify such values, in view of reducing the associated risk, from stages early, such as the pre-adolescence stage(AU)
