Human papillomavirus prevalence in postradiotherapy uterine cervical carcinoma patients: correlation with recurrence of the disease

To understand the role of human papillomavirus (HPV) in recurrence of uterine cervical cancer (CA-CX) after radiotherapy, we have analyzed the HPV prevalence in the exfoliated cells of 56 patients and their corresponding plasma. HPV DNA was detected in exfoliated cells of 78% (44/56) patients (HPV-16, 68%; HPV-18, 14%; HPV-X [other than 16, 18], 11%; and mixed infection of HPV-16 and HPV-18 in three cases). HPV DNA in plasma was present in only 25% (11/44) of the HPV-positive exfoliated cells (positive predictive value, 100%; negative predictive value, 27%) with concordance in HPV types. The recurrence of the disease was significantly associated with the presence of HPV in the exfoliated cell (P = 0.01) and plasma (P = 0.007) as well as high viral load in the exfoliated cell (P = 0.0002). Kaplan–Meier disease-free estimates have also shown the significant association between HPV prevalence in plasma and recurrence of the disease (P = 0.045). Thus, it indicates that in postradiotherapy CA-CX patients, the high viral load in the exfoliated cell as well as HPV presence in the plasma samples could be used in early detection of the patients at increased risk for disease recurrence and progression.

Recently, there has been a steady growth of cervical cancer all over the world, especially in Russia. Patients with cervical cancer have become much younger. At the same time, the human papillomavirus is not only the main factor in the neoplastic process, but it is also one of the most common sexually transmitted infections in the world. The aim of the paper is to assess the prevalence and characteristics of human papillomavirus genotypes in patients with cervical intraepithelial neoplasia. Materials and Methods. During the periodic screening we examined 213 women of a reproductive age with HPV infection. All patients underwent liquid-based cytology and human papillomavirus genotyping by polymerase chain reaction. Results. We revealed that the prevalence of cervical intraepithelial neoplasia among women with papillomavirus infection was 80.3 % (n=171). According to human papillomavirus genotyping, HPV 16 (38 %) and HPV 33 (32 %) prevailed. We also observed positive high correlation between high-grade squamous intraepithelial lesions (HSIL) and HPV 18 (r=+0.759, p=0.001), a negative mean correlation between HPV 45 and low-grade squamous intraepithelial lesions (LSIL) (r=-0.643, p=0.002). A cohort of patients with severe intraepithelial cervical lesions demonstrated high viral load rates. Conclusion. According to the results obtained, we established the dominance of HPV 16 and HPV 33 genotypes in cervical intraepithelial neoplasia. There were significant differences between HSIL and LSIL patients with HPV 18 and HPV 45. There was also a correlation between an increase in the viral load with the severity of the pathological process. Keywords: human papillomavirus, intraepithelial cervical neoplasms, cervical cancer. В последние годы в мире, особенно в России, наблюдается неуклонный рост и «омолаживание» рака шейки матки. При этом вирус папилломы человека является не только основным фактором прогрессирования неопластического процесса, но и одной из наиболее распространенных инфекций, предаваемых половым путем, в мире. Цель. Оценить распространенность и характеристику генотипов папилломавирусной инфекции у пациенток с цервикальными интраэпителиальными неоплазиями. Материалы и методы.

The clinical implications of specific human papillomavirus (HPV) types in invasive cervical carcinomas are only now beginning to be appreciated. The objective of this study was to determine the clinical implications and prognostic value of the HPV genotype in cervical carcinomas. In this study, we employed an HPV DNA chip to detect the type-specific sequence of HPV from cervical swabs taken from women with biopsy-proven neoplastic lesions of the cervix. We divided the patients into four groups: HPV-negative, HPV-16-related, HPV-18-related, and intermediate risk type–related. Associations with clinicopathologic data (stage, histologic type, lymph node status, parametrial invasion, lymphvascular space invasion, tumor size, vaginal involvement) and overall survival were assessed. HPV DNA was detected in 81.4% of the patients, and 19.0% harbored multiple HPV variants. HPV-16-related was the predominant type and was detected in 47.4% (46/97) of the patients. The HPV-16-related types were detected more frequently in patients with squamous cell carcinomas, whereas the HPV-18-related types were more prevalent in cases of adenocarcinomas and adenosquamous carcinomas (P< 0.05). Otherwise, no significant correlations were detected between the HPV genotype and any other clinicopathologic parameters. After a median follow-up of 30 months, the 5-year survival rate was lower in the HPV-18-related patients, but this difference was not found to be statistically significant, according to the results of the log-rank test. We conclude that neither the presence nor type of HPV DNA bears any prognostic significance in cases of cervical carcinoma.

ABSTRACT: Introduction: Human papillomavirus (HPV) is considered a necessary causative agent for developing oropharyngeal, anal and cervical cancer. Among women in Ecuadorian population, cervical cancer ranks as the second most common gynecological cancer. Not many studies about HPV burden have been published in Ecuador, and genotypes distribution has not been established yet. The little data available suggest the presence of other genotypes different than 16 and 18. Objectives: In the present study, we attempt to estimate the prevalence of HPV 16, HPV 18 and other 35 genotypes among Ecuadorian women undergoing cervical cancer screening. The overall prevalence of HPV infection was also estimated. Methods: Routine cervical samples were analyzed using Linear Array(r) HPV Genotyping test (Roche). Results: A total of 1,581 cervical samples obtained from Ecuadorian women undergoing cervical cancer screening were included in this study. HPV DNA was detected in 689 cervical samples (43.58%). Of these samples, 604 (38.20%) were positive for a single HPV genotype, while another 85 (5.37%) samples were positive for multiple HPV types. Genotype 16 (5.50%) resulted in the most frequently detected type in both single and multiple infections. HPV 33 (4.55%) and HPV 11 (3.80%) occupied the second and the third place in frequency among all detected genotypes. Conclusions: Viral genotypes different from HPV 16 and HPV 18 are frequently detected among Ecuadorian women. The overall prevalence of HPV resulted higher than the one reported in other South American countries with a greater burden in the second and third decades of life.

HIV-infected patients are at increased risk of human papillomavirus (HPV) acquisition and HPV-associated diseases. This study set out to determine whether a two-dose (2D) HPV vaccination schedule was sufficient in HIV-infected adolescents with immune reconstitution (IR) following antiretroviral treatment. Participants aged 9–15 years who had CD4 cell counts > 500 cells/mm3 and HIV-1 RNA < 40 copies/mL for at least one year were assigned to the 2D schedule, while older participants or those without IR received a three-dose (3D) schedule. Antibodies to HPV-16 and -18 were measured using a pseudovirion-based neutralization assay. A total of 96 subjects were enrolled; 31.3% and 68.7% received the 2D and 3D schedule, respectively. Of these, 66.7% and 57.6% of the 2D and 3D participants, respectively, were male. The seroconversion rates for HPV-16 and HPV-18 were 100% in all cases, except for HPV-18 in males who received the 3D schedule (97.4%). In males, the anti-HPV-16 geometric mean titers (GMTs) were 6859.3 (95% confidence interval, 4394.3–10,707.1) and 7011.1 (4648.8–10,573.9) in the 2D and 3D groups (p = 0.946), respectively, and the anti-HPV-18 GMTs were 2039.3 (1432.2–2903.8) and 2859.8 (1810.0–4518.4) in the 2D and 3D (p = 0.313) groups, respectively. In females, the anti-HPV-16 GMTs were 15,758.7 (8868.0–28,003.4) and 26,241.6 (16,972.7–40,572.3) in the 2D and 3D groups (p = 0.197), respectively, and the anti-HPV-18 GMTs were 5971.4 (3026.8–11,780.6) and 9993.1 (5950.8–16,781.1) in the 2D and 3D groups (p = 0.271), respectively. In summary, a 2D schedule is as immunogenic in young adolescents with IR as a 3D schedule in older subjects and those without IR.

Background: This study investigated prospectively the role of human papillomavirus (HPV) in paranasal inverted papilloma (IP). Methods: HPV presence and viral load and physical status of HPV-16 were examined by polymerase chain reaction-based methods using fresh frozen samples obtained from 13 patients with IP (IP group), 11 with squamous cell carcinoma in the maxillary sinus (SCC group) and 39 with chronic inflammatory lesions (inflammatory group). Results: The presence of the HPV genome was detected in 46.1%, 27.3% and 7.6% of patients in the IP, SCC and inflammatory groups, respectively. The IP group showed significantly higher HPV-positive rates than the inflammatory group. All types of HPV detected were high-risk HPV, especially HPV-16. The relative HPV-16 copy numbers varied from 2.5 to 1524.1 per 50 ng genomic DNA. The viral load was higher in the IP and SCC groups than in the inflammatory group. In the IP group, no significant relationship was found between HPV-16 viral load and clinical characteristics, or between physical status and clinical characteristics. One patient with IP and concomitant squamous cell carcinoma, however, showed high viral load and integration. Conclusions: HPV infection is involved in the pathogenesis of IP, and high viral load and integration of HPV have an important role in malignant lesion in association with IP.

The aim of this study was to evaluate the accuracy of human papillomavirus (HPV) genotyping by a polymerase chain reaction (PCR)-based genechip method and to determine the prognostic value of HPV genotype in bulky stage IB or IIA cervical carcinoma treated with neoadjuvant chemotherapy (NAC) and radical surgery. A total of 149 patients had adequate tissue for the study. The SPF1/GP6+ primers were used to amplify a 184 bp fragment. The amplimers were submitted for direct sequencing and hybridization with a genechip using revert-blot detection of 39 types of HPV DNA in a single reaction. Two runs of PCR with respective hybridization were performed for each tumor. The complete concordance of HPV genotyping was 80.5% (120/149) of the paired genechip results. The kappa coefficient was 0.634 (P < 0.0001). HPV DNA sequences were detected in 100% of the specimens, among which 67.8% harbored single type and 32.2% contained multiple types. HPV-16 was detected in 98.7%, HPV-18 in 22.8%, HPV-31 in 0.7%, HPV-45 in 1.3%, HPV-52 in 2.0%, HPV-58 in 6.7%, HPV-59 in 4.7%, and HPV-67 in 0.7%. In multivariate analyses, the HPV genotype [HPV-18 or HPV-16 and HPV-18 only versus all others: relative risk (RR), 2.33; 95% CI, 1.17–4.64; P = 0.016] and pre-NAC tumor size (>5 versus ≤5 cm: RR, 2.25; 95% CI, 1.13–4.48; P = 0.021) were significantly related to overall survival. This PCR-based genechip method is sensitive and reproducible for HPV genotyping. The association of HPV-18 or HPV-16 and HPV-18 with poor outcome in cervical carcinoma treated with NAC plus radical surgery is confirmed.

Long Term Follow Up

The role of human papillomavirus (HPV) in anal squamous cell carcinoma (ASCC) carcinogenesis has been clearly established, involving the expression of viral oncoproteins and optional viral DNA integration into the host genome. In this article, we describe the various mechanisms and sites of HPV DNA insertion and assess their prognostic and predictive value in a large series of patients with HPV-positive ASCC with long-term follow-up. We retrospectively analyzed 96 tumor samples from 93 HPV-positive ASCC patients using the Capture-HPV method followed by Next-Generation Sequencing, allowing determination of HPV genotype and identification of the mechanisms and sites of viral genome integration. We identified five different mechanistic signatures of HPV insertions. The distribution of HPV signatures differed from that previously described in HPV-positive cervical carcinoma (p < 0.001). In ASCC samples, the HPV genome more frequently remained in episomal form (45.2%). The most common signature of HPV insertion was MJ-SC (26.9%), i.e., HPV–chromosomal junctions scattered at different loci. Functionally, HPV integration signatures were not associated with survival or response to treatment, but were associated with viral load (p = 0.022) and PIK3CA mutation (p = 0.0069). High viral load was associated with longer survival in both univariate (p = 0.044) and multivariate (p = 0.011) analyses. Finally, HPV integration occurred on most human chromosomes, but intragenic integration into the NFIX gene was recurrently observed (n = 4/51 tumors). Overall, the distribution of mechanistic signatures of HPV insertions in ASCC was different from that observed in cervical carcinoma and was associated with viral load and PIK3CA mutation. We confirmed recurrent targeting of NFIX by HPV integration, suggesting a role for this gene in ASCC carcinogenesis.

Abstract Background We studied the association between human papillomavirus (HPV) viral load (VL) and HPV concordance. Methods The HITCH cohort study included young, heterosexual, recently formed, sexually active couples. Questionnaires and genital samples were collected at 0 and 4 months. Samples were tested for HPV DNA by polymerase chain reaction (PCR; Linear Array). VLs of HPV6/11/16/18/31/42/51 were quantified using type-specific real-time PCR. Correlations between VL and type-specific HPV prevalence and incidence were evaluated using multilevel, mixed-effects linear/logistic regression models. Results We included 492 couples. VLs were higher in penile than vaginal samples. VL at subsequent visits correlated significantly within men (r, 0.373), within women (r, 0.193), and within couples (r range: 0.303–0.328). Men with high VL had more type-specific persistent HPV infections (odds ratio [OR], 4.6 [95% confidence interval {CI}, 2.0–10.5]). High VL in men was associated with prevalent (OR, 5.3 [95% CI, 2.5–11.2]) and incident (OR, 6.7 [95% CI, 1.5–30.7]) type-specific HPV infections in their partner. Women’s VL was associated with type-specific HPV prevalence in their partner at the same (OR, 5.9) and subsequent (OR, 4.7) visit. Conclusions Persistent HPV infections have limited VL fluctuations. VL between sex partners are correlated and seem predictive of transmission episodes.

Oncogenic Hpv

Abstract 12 A causal role for human papillomavirus (HPV) associated cancers of vulva, penile, and anus is supported by evidence from molecular and epidemiologic investigations. This study detected the oncogenic HPV genotypes in vulva cancers, penile cancers and anal cancers by a cross-sectional descriptive study in 2013. A total of 100 paraffin embedded biopsy tissues of histologically confirmed vulva cancers, penile cancers and anal cancers within past five years during 2008 and 2012 were studied. Those cases were 61 vulva cancers from Central Women Hospital, Yangon and 30 penile cancers and 9 anal cancers from Yangon General Hospital. HPV-DNA testing and genotyping were performed by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP). Consensus sequence primer pairs within the E6 andE7 open reading were used to amplify oncogenic HPV genotypes (HPV-16,-18,-31,-33,-35,-52b,-58). Restriction enzymes were used for determination of specific HPV genotypes. HPV was identified in 36.1% of vulva cancers (22/61), 26.7% of penile cancers (8/30) and 44.4% of anal cancers (4/9). In vulva cancers, HPV-33 was the most common genotype (40.9%) followed by HPV-16 (31.8%), HPV-31 (22.7%), and HPV-18 (4.6%). In penile cancers, HPV-16 (62.5%) was the most common genotype followed by HPV-33 (25%) and HPV-18 (12.5%). Among anal cancers, the most frequent genotypes were HPV-16 (75%) and HPV-18 (25%). This study is the first report of evidence based oncogenic HPV genotypes in vulva cancers, penile cancers and anal cancers in Myanmar. This research provides the valuable information in understanding the burden of HPV associated cancers of the vulva, penile, and anus in Myanmar and the consideration of the effectiveness of prophylactic HPV vaccination in not only cervical cancer but also non-cervical cancers.
