5084 Background: To estimate the prevalence and genotypes of high-risk human papillomavirus (HPV) among older Japanese women, using liquid-based cytology (LBC). Methods: ThinPrep LBC specimens were collected from 11,039 Japanese women (age range, 14-98 years). After classifying cytodiagnosis, specimens were analyzed for HPV DNA using the multiplex polymerase chain reaction method. Cervical smear specimens from 1,302 women showed positive results. To examine the prevalence of HPV in women defined as negative for intraepithelial lesion or malignancy (NILM), 2,563 samples were randomly selected from the remaining 9,737 women. Comparisons were made between women ≥50 years of age (older age group) and women <50 years of age (younger age group). Written informed consent was obtained from all patients. In this study, the high-risk HPV genotypes encountered were 16, 18, 31, 33, 35, 45, 52, and 58. Results: In the older age group with abnormal smear findings, HPV genotypes were detected in 49.7% (148/298), including high-risk HPV genotypes in 40.9% (122/298). In the younger age group with abnormal smear findings, HPV genotypes were detected in 71.7% (720/1004), including high-risk HPV genotypes in 58.1% (583/1,004). In NILM, HPV-positive rates were 4.5% (39/873) in the older age group and 11.8% (199/1,690) in the younger age group. In high-grade squamous intraepithelial lesion (HSIL) or more severe cytological findings, HPV genotypes of each group (older age group/younger age group) were detected in 61.7%/83.1%, and high-risk HPV genotypes were detected in 56.4%/74.7% of women. In positive cervical smears, HPV 16 was the most frequently detected (28.5%) in the younger age group, while HPV 52 (31.3%) and 58 (27.2%) were detected more frequently than HPV 16 (18.4%) in the older age group. Conclusions: In Japan, although HPV infection as a cause of abnormal cervical cytology is more frequent among younger age groups than in older age groups, high-risk HPV infection was more highly associated with older individuals (older age group/younger age group: abnormal smear findings, 82.4%/81.0%; HSIL or more severe cytological findings, 91.3%/89.9%). In older age groups, HPV 52 and 58 were more frequent than HPV 16.

Background and objective: Considering the importance of HPV in cancer etiology, awareness of HPV prevalence and frequency of high-risk genotypes could help improve health care system management. We analyzed HPV prevalence in women forms different provinces of Iran that is the largest sample till now. Material and Methods: In this retrospective cross-sectional study, 2969 outpatient and suspicious women aged 17- 78 referred to Noor pathobiology laboratory from 24 provinces of Iran were studies. DNA extraction and PCR were performed on samples and then HPV genotypes were also determined using hybridization kit. Results: HPV DNA was detected in 29.3% of valid liquid-based samples. Among HPV positive cases, 67.2% and 52.0% accounted for high-risk and low-risk HPV subtypes, respectively. In patients with high-risk HPV types, HPV16 was confirmed as predominate type (30.5%) followed by HPV53 (17.3%) and HPV39 (13.3 %). HPV6 was found as the most common low-risk HPV type with 60.6% frequency rate followed by HPV11 (17.9%) and HPV81 (8.6%) in this age group. It was apparent that age group >25 years accounted the highest frequency of HPV positivity. The prevalence of HPV was significantly different among different age groups (p<0.0001). Conclusion: It can be concluded that HPV infection is currently at a considerable high level in Iran. Looking at the high risk and oncogenic HPV subtypes frequency especially in younger age groups, a concern could be noticed about HPV relevant cancers which can be prevented by commercial and approved HPV vaccines.

Abstract Background The causative agent of cervical cancer referred to as Human papillomavirus (HPV) remains a real public health problem. Many countries in West Africa, such as Togo have no data on the high-risk HPV (HR-HPV) infection and genotypes distribution. In order to fill the knowledge gap in the field in Togo, the main objective of this study was to determine the prevalence of pre-cancerous lesions of the cervix and HR-HPV genotypes among Togolese women. Methods Samples were collected from 240 women by introducing a swab in the cervix. Then, the screening of precancerous cervical lesions using the visual inspection with acetic acid and lugol (VIA / VIL) was conducted. The HR-HPV genotypes were characterised by real-time multiplex PCR. Results Out of 240 women recruited, 128 (53.3%) were infected by HR-HPV. The most common genotypes were HPV 56 (22.7%), followed by HPV 51 (20.3%), HPV 31 (19.5%), HPV 52 (18.8%) and HPV 35 (17.2%). The least common genotypes were HPV 33 (2.3%) and HPV 16 (2.3%). Among the women, 1.3% (3/240) were positive to VIA/VIL. Conclusion This study allowed HR-HPV genotypes to be characterised for the first time in Lomé, Togo. This will help in mapping the HR-HPV genotypes in West Africa.

This article is a preliminary investigational study that is aimed at giving hints about the interesting biomarkers involved in the transition process from low-grade cervix lesion to invasive cervical cancer. Our study focuses on the risk factors and tumour molecular changes in one patient. First in 1986, she was diagnosed a preinvasive cervix lesion. Then, 16 years later, she was diagnosed an invasive cervical cancer. The 2002 diagnosis was a squamous cell carcinoma of the cervix, stage IIIB (FIGO), whereas in 1986, she had been diagnosed a high-grade squamous intraepithelial cervical lesion. Retrospectively, the analysis of samples of preneoplastic lesions and invasive cervical cancer confirmed the histopathological diagnoses and detected the presence of HPV type and HPV-16 variants, as well as the overexpression of proteins such as hTERT, IGF1Rα, IGF1Rβ, CAIX, and GLUT1. Finally, the Arg72Pro polymorphism was detected in TP53. The role of high-risk HPV and HPV-16 variants and of hTERT, IGF1Rα, IGF1Rβ, CAIX, and GLUT1 variations seemed confirmed in the development and progression of cervical cancer. As a result, analyzing the molecular changes in one and same tumour that progresses from a low-grade cervix lesion to invasive cervical cancer could provide valuable information in order to improve detection, diagnosis, and treatment in the future.

Abstract Background Ensuring the quality of anthropometry data is paramount for getting accurate estimates of malnutrition prevalence among children aged 6–59 months in humanitarian and refugee settings. Previous reports based on data from Demographic and Health Surveys suggested systematic differences in anthropometric data quality between the younger and older groups of preschool children. Methods We analyzed 712 anthropometric population-representative field surveys from humanitarian and refugee settings conducted during 2011–2018. We examined and compared the quality of five anthropometric indicators in children aged 6–23 months and children aged 24–59 months: weight for height, weight for age, height for age, body mass index for age and mid-upper arm circumference (MUAC) for age. Using the z-score distribution of each indicator, we calculated the following parameters: standard deviation (SD), percentage of outliers, and measures of distribution normality. We also examined and compared the quality of height, weight, MUAC and age measurements using missing data and rounding criteria. Results Both SD and percentage of flags were significantly smaller on average in older than in younger age group for all five anthropometric indicators. Differences in SD between age groups did not change meaningfully depending on overall survey quality or on the quality of age ascertainment. Over 50% of surveys overall did not deviate significantly from normality. The percentage of non-normal surveys was higher in older than in the younger age groups. Digit preference score for weight, height and MUAC was slightly higher in younger age group, and for age slightly higher in the older age group. Children with reported exact date of birth (DOB) had much lower digit preference for age than those without exact DOB. SD, percentage flags and digit preference scores were positively correlated between the two age groups at the survey level, such as those surveys showing higher anthropometry data quality in younger age group also tended to show higher quality in older age group. Conclusions There should be an emphasis on increased rigor of training survey measurers in taking anthropometric measurements in the youngest children. Standardization test, a mandatory component of the pre-survey measurer training and evaluation, of 10 children should include at least 4–5 children below 2 years of age.

Abstract Abstract 4963 Myelodysplastic syndrome (MDS) is a disease of the elderly, but can also affect younger people. Age is known to be an important prognostic factor in MDS but age variable is not included in most prognostic scoring systems because it is not thought as a disease-related variable. Many reports have showed that MDS is seen one to two decades earlier in Far Eastern countries than Western countries. We retrospectively investigated the differences in biologic features and clinical outcomes according to different age groups in Korean patients with MDS. Primary end points of our study were overall survival (OS) and progression-free survival (PFS). PFS was defined as time from diagnosis to AML progression or death. About one third of the patients received intensive treatment including chemotherapy, hypomethylating treatment or hematopoietic cell transplantation. Therefore, all survival data were censored at the start of intensive treatment to eliminate the influence of the treatments on clinical outcomes. A total of 403 patients, 248 males and 155 females, were included in this study. Median age was 54 years. We divided the patients into three age groups: ≤50 years (n=181), 51 to 60 (n=81), and over 60 (n=141). Baseline biologic features were significantly different according to three age groups: with increasing age, more male preponderance (P=0.009), more BM blast percentage (P<0.001), more advanced WHO subtype (P<0.001), higher proportion of high risk cytogenetic features (P=0.052; ≤60 vs. >60, P=0.011), poorer ECOG performance status (P=0.004), higher IPSS risk group (P=0.019). Five-year survival probabilities were significantly different according to age groups (≤ 50 vs. 51–60 vs. > 60; OS, 66.8% vs. 28.5% vs. 12.2%, P<0001; PFS, 58.5% vs. 37.9% vs. 12.3%, P<0.001). Survivals were also significantly different according to age groups in both IPSS Low/INT-1 (P<0.001 for OS, P=0.001 for PFS) and IPSS INT-2/High risk group (P=0.026 for OS, P=0.069 for PFS). Cox proportional hazards models also demonstrated that age group was an independent prognostic factor for survivals: ≤ 50 vs. 51–60 and > 60; OS, RR 2.3 (P=0.037) and RR 4.6 (P<0.001); PFS, RR 1.3 (P=0.449) and RR 2.0 (P=0.012). Conclusion: Biologic features and clinical outcomes were significantly different among age groups in MDS. Clinical outcomes were better in younger age group independently of biologic features. Survivals (OS & PFS) were better in younger age group and survival differences by age groups were observed in both lower and higher risk MDS, suggesting that age stratification should be considered in treatment decision and clinical trial design.

Chip Analysis

This study was designed to investigate the genotypes of human papillomavirus (HPV) in Korean women who had abnormal cervical cytology and to evaluate the clinical accuracy of HPV DNA chip analysis for the diagnosis of cervical neoplasia. Liquid-based cytology preparations, HPV DNA chip analysis, and cervical biopsy were performed in 2358 women. High-risk HPV was identified in 23.5% of 1650 histologically confirmed normal samples (including cervicitis and squamous metaplasia) and in 81.8% of 708 samples with cervical intraepithelial neoplasia (CIN) and carcinoma (P< 0.01). The major prevalent high-risk HPV genotypes in 381 samples of CIN II/III were HPV-16, -58, -33, and -31, in order of prevalence rate (average overall, 78.0%), and HPV-16, -18, -58, and -33 (average overall, 81.2%) in 133 samples of squamous cell carcinoma (SCC). The infection rate of HPV-16 was significantly higher than that of other high-risk HPV genotypes in all normal, CIN, and SCC cases (P< 0.01) and increased with more advanced squamous cervical lesions (P< 0.01). The detection accuracy of high-risk HPV using HPV DNA chip analysis for CIN II or worse was as follows: sensitivity 84% (81–87%), specificity 72% (70–74%), positive predictive value 47% (44–50%), and negative predictive value 94% (92–95%). These results suggest that HPV DNA chip analysis may be a reliable diagnostic tool for the detection of cervical neoplasia and that there are geographic differences in the distribution of high-risk HPV genotypes.

Objective: To investigate the epidemiological characteristics and genotypes of human papillomavirus (HPV) infection in Mianyang. Methods: The cervical samples of 27,040 patients, who visited the Department of Gynecology of The Third Hospital of Mianyang from January 2018 to January 2020, were collected. Results: The HPV-positive infection rate was 21.40% (5,787/27,040); the single HPV infection rate was 72.04% (4,169/5,787); the double HPV infection rate was 19.73% (1,142/5,787); the triple and above HPV infection rate was 8.22% (476/5,787); the top five high-risk HPV subtypes with the highest infection rates were HPV52, 16, 58, 53, and 51, while the top five low-risk HPV subtypes with the highest infection rates were HPV81, 42, 43, 6, and 11; there were significant differences in the HPV-positive infection rate, high-risk infection rate, low-risk infection rate, and multiple infection rate among different age groups (P < 0.05). Conclusion: The HPV infection rate in Mianyang was 21.4%, in which the majority of the cases were single infection; the high-risk HPV subtypes were HPV52, 16, 58, 53, and 51; the HPV-positive infection rate, high-risk infection rate, low-risk infection rate, and multiple infection rate were high in the middle but low at both ends in the context of age distribution; the top three age groups with the highest infection rates were 45-49, 40-44, and 30-34.

Human papillomavirus (HPV) infection is thought to be strongly associated with the precarcinomatous state cervical intraepithelial neoplasia (CIN) and cervical carcinoma. To accurately assess the correlation between HPV detection profiles and CIN, the uniplex E6/E7 polymerase chain reaction (PCR) method was used. We detected HPV (37 genotypes) in 267 CIN cases. The detection of a single high-risk HPV genotype occurred in 69.7% of CIN1 and worse than CIN1 (CIN1+) cases whereas other types were detected in 11.6% of cases. Codetection of high-risk HPV genotypes occurred in 4.9% of CIN1+ cases. The high-risk genotype HPV16 was the most frequently detected genotype in CIN1+ lesions; the genotype HPV34 (not a high-risk type) was detected in some CIN3 cases. Furthermore, HPV codetection may not be associated with CIN grades. These results suggest that various HPV genotypes are associated with CIN across all analyzed cases.

Human papillomavirus (HPV) type-specific distribution was evaluated in genital samples collected from 654 women from the South of Italy undergoing voluntary screening and correlated with cyto-histological abnormalities. HPV DNA was detected in 45.9% of the samples, 41.7% of which had multiple infection and 89.0% had high-risk HPV infection. The prevalence of HPV infection and the rate of multiple infections decreased with age, suggesting natural selection of HPV types with better fitness. In line with other Italian studies, the most common HPV types were HPV-6 and HPV-16, followed by HPV-51, HPV-31, HPV-53, and HPV-66, in women with both normal and abnormal cytology. Cervical intraepithelial lesions grade 2 or 3 were associated with high-risk HPV-16, HPV-18, HPV-31, and HPV-51 infection. These data indicate that prophylactic HPV vaccination is expected to reduce the burden of HPV-related cervical lesions in this population, but also suggest the potential utility of new vaccines with larger type coverage.

55 Background: In men high-risk human papilloma viruses (HPVs) have been implicated in causing cancer of the penis, anus, and oropharynx. HPV infection, specifically HPV 16, is currently one of the most common causes of oropharyngeal cancer. National population-based surveys provide estimates of population-specific prevalence, trend, and determinants to identify the burden of high-risk HPV in the oropharynx of men. Methods: We calculated HPV infection prevalence by oral testing in the US from 1999-2012 National Health and Nutrition Examination Survey (NHANES) to obtain a representative sample of non-institutionalized civilian population. We provided epidemiology of HPV infection for both females and males with prevalence estimates, unadjusted odds ratio (OR) with 95% confidence interval (95%CI). Analysis was performed by SAS v9.3 with complex sampling design. Results: Among HPV-positive persons, high-risk HPV infection (16, 18, 26, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 68, 73, 82) was more prevalent for men (79.4%) than for women (20.6%). Men also had the highest prevalence for each high-risk type tested. Notably, men held 84.9% of the HPV 16 burden, which has the highest risk for orophargyngeal cancer. Mexican-American men had lower odds of high-risk HPV infection than White men (OR=0.47; 95%CI=0.261, 0.86). Further, divorced/separated/widowed men had lower (0.48; 0.26, 0.88) and never married men had greater (1.76; 1.01, 3.07) odds of high-risk HPV compared to men who are married/living with partner. Conclusions: Using a large population-based survey, our results show increased prevalence of high-risk HPV infection in men. Stratification by ethnicity and marital status will increase understanding and awareness of the burden and demographic disparities of potentially oncogenic HPV infections in men and may provide a base for culturally and gender competent oropharyngeal cancer screening programs. Recognizing demographic disparities and behaviors could guide further research into risk factors and conditions that guide the prevalence of HPV infection and oropharyngeal cancer in specific male populations.
