HPV genotyping by L1 amplicon sequencing of archived invasive cervical cancer samples: a pilot study. Infect Agent Cancer 2022; 17:44. [PMID: 35945577 PMCID: PMC9361560 DOI: 10.1186/s13027-022-00456-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2022] [Accepted: 08/02/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Human papillomavirus (HPV) is the primary cause of invasive cervical cancer (ICC). The prevalence of various HPV genotypes, ranging from oncogenically low- to high-risk, may be influenced by geographic and demographic factors, which could have critical implications for the screening and prevention of HPV infection and ICC incidence. However, many technical factors may influence the identification of high-risk genotypes associated with ICC in different populations. METHODS We used high-throughput sequencing of a single amplicon within the HPV L1 gene to assess the influence of patient age, race/ethnicity, histological subtype, sample type, collection date, experimental factors, and computational parameters on the prevalence of HPV genotypes detected in archived DNA (n = 34), frozen tissue (n = 44), and formalin-fixed paraffin-embedded (FFPE) tissue (n = 57) samples collected in the Los Angeles metropolitan area. RESULTS We found that the percentage of off-target human reads and the concentration of DNA amplified from each sample varied by HPV genotype and by archive type. After accounting for the percentage of human reads and excluding samples with especially low levels of amplified DNA, the HPV prevalence was 95% across all ICC samples: HPV16 was the most common genotype (in 56% of all ICC samples), followed by HPV18 (in 21%). Depending upon the genotyping parameters, the prevalence of HPV58 varied up to twofold in our cohort. In archived DNA and frozen tissue samples, we detected previously established differences in HPV16 and HPV18 frequencies based on histological subtype, but we could not reproduce those findings using our FFPE samples. CONCLUSIONS In this pilot study, we demonstrate that sample collection, preparation, and analysis methods can influence the detection of certain HPV genotypes and must be carefully considered when drawing any biological conclusions based on HPV genotyping data from ICC samples.

Abstract
BACKGROUND Persistent human papillomavirus (HPV) infection is a key factor for the development and progression of cervical cancer. We sought to identify the type-specific HPV prevalence by cervical cytology and assess disease progression risk based on high-risk persistent HPV infection in South Korea. METHODS To investigate the HPV prevalence by Pap results, we searched seven literature databases without any language or date restrictions until July 17, 2019. To estimate the risk of disease progression by HPV type, we used the Korea HPV Cohort study data. The search included the terms "HPV" and "Genotype" and "Korea." Studies on Korean women, type-specific HPV distribution by cytological findings, and detailed methodological description of the detection assay were included. We assessed the risk of disease progression according to the high-risk HPV type related to the nonavalent vaccine and associated persistent infections in 686 HPV-positive women with atypical squamous cells of uncertain significance or low-grade squamous intraepithelial lesions from the Korea HPV Cohort Study. Type-specific HPV prevalence was the proportion of women positive for a specific HPV genotype among all HPV-positive women tested for that genotype in the systematic review. RESULTS We included 23 studies in our review. HPV-16 was the most prevalent, followed by HPV-58, -53, -70, -18, and -68. In women with high-grade squamous intraepithelial lesions, including cancer, HPV-16, -18, and -58 were the most prevalent. In the longitudinal cohort study, the adjusted hazard ratio of disease progression from atypical squamous cells of uncertain significance to high-grade squamous intraepithelial lesions was significantly higher among those with persistent HPV-58 (increase in risk: 3.54-5.84) and HPV-16 (2.64-5.04) infections. CONCLUSIONS While HPV-16 was the most prevalent, persistent infections of HPV-16/58 increased the risk of disease progression to high-grade squamous intraepithelial lesions. Therefore, persistent infections of HPV-16 and -58 are critical risk factors for cervical disease progression in Korea. Our results suggest that equal attention should be paid to HPV-58 and -16 infections and provide important evidence to assist in planning the National Immunization Program in Korea.

Abstract
Human papillomavirus (HPV) infection is closely associated with cervical cancer. This study analyzed HPV genotype prevalence in 75 cases of formalin-fixed paraffin embedded (FFPE) tissue samples from patients diagnosed with cervical cancer. Genotype prevalence was assessed using Reverse Blot Assay (REBA) and quantitative polymerase chain reaction (qPCR), which target the HPV L1 and HPV E6/E7 genes, respectively. HPV DNA chip tests were also performed using liquid based preparation (LBP) cytological samples from the same patients who provided the FFPE histological samples. We observed a slight difference in HPV genotype distribution as assessed by DNA chip versus REBA. One possible explanation for this difference is that normal regions could be mixed with lesion regions when cytological samples are extracted from each patient with cancer. For the detection of moderate dysplasia, the main target of diagnosis, this difference is anticipated to be greater. We also made several unexpected observations. For example, HPV multi-infection was not detected. Moreover, the rate of HPV positivity varied radically depending on the cancer origin, e.g. squamous cell carcinoma versus adenocarcinoma. Our results imply that it is important to determine whether cytological specimens are suitable for HPV genotyping analysis and cervical cancer diagnosis. Future research on the mechanisms underlying cervical cancer pathogenesis is also necessary.

PLoS One 2015; 10:e0140336.

Abstract
Detecting high-risk (HR) HPV is important for clinical management of women with persistent HPV-positive and Pap-negative results. The Cobas 4800 HPV test is the first FDA-approved HPV DNA test that can be used alone as a first-line screening tool. The HPV 9G DNA chip test is a PCR-based DNA microarray assay. We evaluated the patients of consecutive HPV-positivity on HPV 9G DNA chip test without cytologic abnormalities. We then compared the performances of HPV 9G DNA chip and the Cobas 4800 HPV tests for detecting HR HPV with each other and confirmed HPV genotyping using direct sequencing. All 214 liquid-based cytology specimens were collected from 100 women with consecutive HPV-positive and Pap-negative results on the HPV 9G DNA chip test between May 2012 and Dec 2013, but only 180 specimens were available for comparing HPV test results. The HPV 9G DNA chip and the Cobas 4800 HPV tests agreed with each other in 81.7% of the samples, and the concordance rate was greater than 97.2% for detecting HPV-16 or -18. For HR genotypes other than HPV types 16 and 18, the two tests agreed for 81.1% of the samples. The sensitivity of both assays for detecting HR HPV was 100%, regardless of HR genotypes. The HPV 9G DNA chip test may be as effective as the Cobas 4800 HPV test in detecting HR HPV, and has a similar ability to identify HPV-16 and -18.

Abstract
BACKGROUND Human papillomavirus (HPV) is an oncogenic virus in cervical cancer and most invasive carcinomas (ICs) are caused by HPV16 and 18. However, the roles and contributions of other uncommon and rare genotypes remain uncertain. METHODS HPV genotypes were retrospectively assessed using an HPV DNA chip that can specify up to 32 HPV genotypes. We arbitrarily regarded genotypes accounting for less than 6% of the total as uncommon and rare genotypes. RESULTS A total of 3,164 HPV-positive cases were enrolled. In groups 2A, 2B, 3, and unclassified HPV genotypes, 2.4% of cases with uncommon HPV genotypes (68, 26, 34, 53, 66, 69, 70, 73, 40, 42, 43, 44, 54, 55, 61, 62, 6, and 11) showed high grade squamous intraepithelial lesions and ICs. There were no HPV32- and 57-infected cases. CONCLUSIONS We found that the uncommon and rare HPV genotypes may provide incremental etiologic contributions in cervical carcinogenesis, especially HPV68, 70, and 53. Further studies on these uncommon and rare HPV genotypes will be of importance in establishing the significance of genotypes in different regions, especially in planning a strategy for further vaccine development as well as follow-up on the effectiveness of the currently used vaccines.

Abstract
Purpose Cervical cytology and human papillomavirus (HPV) DNA co-testing is recommended as a screening method for detecting cervical lesions. However, for women who are HPV-positive but cytology-negative, the appropriate management and significance of HPV-58 infection remain unknown. Methods This study of prevalent HPV detected at baseline with a median follow-up of 3.2 years evaluated the risk factors associated with cervical abnormalities and assessed the significance of HPV-58 infection. A total of 265 women were enrolled. All high-grade squamous intraepithelial lesions (HSIL) that were detected by cytology were confirmed by histology. Histological diagnoses of cervical intraepithelial neoplasia 2/3 were classified as HSIL. Women were classified into four groups according to the HPV genotype that was detected at their first visit: HPV-58 (n = 27), HPV-16 (n = 52; 3 women had HPV-58 co-infection), ten other high risk (HR) types (n = 79), or low/undetermined risk types (n = 107). Results Of 265 women, 20 (7.5%) had HSIL on their follow-up examinations. There were significant differences in the cumulative incidence of HSIL between the four groups (p<0.001). The 5-year cumulative incidence rates of HSIL were 34.0% (95% CI: 17.3–59.8%) in HPV-58 positive cases, 28.0% (95% CI: 13.8–51.6) in HPV-16 positive cases, 5.5% (95% CI: 2.1–14.0%) in one of the ten other types of HR-HPV positive cases, and 0% in women with low/undetermined risk HPV. When seen in women with HR-HPV (n = 158), persistent HPV infection was a significant factor associated with the development of HSIL (hazard ratio = 15.459, 95% CI: 2.042–117.045). Women with HPV-58 had a higher risk (hazard ratio = 5.260, 95% CI: 1.538–17.987) for the development of HSIL than women with HPV-16 (hazard ratio = 3.822, 95% CI: 1.176–12.424) in comparison with women with other types of HR-HPV. Conclusion HPV-58 has a high association with the development of HSIL in women who are HPV-positive and cytology-negative.

Abstract
OBJECTIVE Dynamin 2, which plays a role in endocytosis, is known to be required for HPV infection on host cells. We investigated dynamin 2 as a biomarker in grading of cervical intraepithelial neoplasia (CIN) by comparing with Ki-67 expression and the type of HPV infection (low-risk vs. high-risk). STUDY DESIGN We performed immunohistochemical stains of dynamin 2 and Ki-67 on tumor samples of patients with CIN and the type of HPV infection was investigated. RESULTS All the patients with reactive changes (n=7) or normal (n=4) did not show dynamin 2 expression. There were 33, 14, and 12 cases with CIN I, II, and III, respectively, and there was a negative correlation between the degree of dynamin 2 expression and the severity of CIN lesions with statistical significance (P<0.001). Negative expression of dynamin 2 was more sensitive for the detection of CIN II/III than high expression (2+) of Ki-67 (96.2% vs. 73.1%, P=0.041). Among patients in whom HPV infection was detected, the degrees of dynamin 2 expression were not associated with the type of HPV infection (low-risk vs. high-risk). Overall, there was a negative correlation between the expression patterns of Ki-67 and dynamin 2. CONCLUSION We found that dynamin 2 may be a helpful biomarker in grading of CIN lesions and a candidate biomarker for detecting low grade CIN with high sensitivity.

She was taking tacrolimus, an immunosuppressive agent, after living-related liver transplantation. The vulvar masses were microscopically proved as vulvar intraepithelial neoplasm II and III, even squamous cell carcinoma in situ. Human papillomavirus subtypes (69 and 73) and human papillomavirus types (66, 70, 73, and 43) were detected in the vulvar mass and the cervicovaginal smear, respectively. The outcome of liver transplantation for children has been markedly improved during the last several decades. However, the present case highlights the need to perform periodic genital examinations for the adolescents after liver transplantation. In addition to the high risk and probable high subtypes, uncommonly found human papillomavirus subtypes were extracted from her vulvar cancer. The present case is the first to show the possible relationship between previously unknown and uncommon human papillomavirus subtypes and pediatric post-transplant vulvar squamous cell carcinoma. More attention should be paid to the vulvar and cervical surveillance of pediatric transplant recipients by both medical specialists and general physicians.
