Cancer Review

The important role of human papillomavirus (HPV) of high carcinogenic risk in the emergence and development of cervical cancer is undeniable. Approximately 90 % of cases of verified cervical cancer are HPV positive. The level of infection with this virus exceeds that of gonococci, chlamydia and yeast infections. Currently, one of the most discussed issues is the possibility of the association of HPV with the risk of developing malignant neoplasms when localized in organs that are anatomically close to the cervix. One of these localizations is the body of the uterus. It is known that endometrial cancer is based on its pronounced hormone dependence. Nevertheless, many factors are involved in the carcinogenesis of endometrial neoplasms, including genetic and epigenetic disorders, as well as risk factors, which include alimentary, hormonal, hereditary causes. At the same time, a controversial issue is the involvement of HPV in the development of this type of cancer. The data on the presence of HPV in endometrial cancer are extremely contradictory: the researchers claim both the complete absence of the effect of the virus on the development of this type of cancer, and the detection of HPV in 60–80 % of cases of tumors. In this regard, it becomes necessary to systematize the currently available research results on this issue and to conduct a meta-analysis of the association of HPV infection with the risk of endometrial cancer.

Hpv Prevalence

ObjectiveHuman papillomavirus (HPV) infection causes multiple cancers in both women and men. In China, both HPV vaccination and cervical cancer screening coverages are low. We aim to investigate the temporal and geographical trends of HPV DNA prevalence in heterosexual men, women, men who have sex with men (MSM) and people living with HIV (PLHIV) in China.MethodsWe conducted a systematic review, collecting publications in PubMed, Web of Science, China National Knowledge Infrastructure (CNKI) and Wanfang Data from January 2000 to May 2017. A total of 247 studies were selected for this meta-analysis to estimate pooled HPV prevalence, incidence of cervical cancer and risk of infection for subgroups. Meta-regression was applied to identify contributing factors to prevalence heterogeneities.ResultsThe national HPV prevalence was 15.6% (95% CI (14.4% to 16.9%)) in women with normal cervical cytology, and Central China had the highest prevalence (20.5% (15.2% to 25.8%)). HPV prevalence in heterosexual men (14.5% (11.3% to 17.7%)) was comparable with that of women (OR=1.09 (0.98 to 1.17)), but HPV prevalence in MSM (59.9% (52.2% to 67.6%)) was significantly higher than that in heterosexual men (OR=8.81 (8.01 to 9.69)). HIV-positive women (45.0% (38.4% to 51.6%)) and HIV-positive MSM (87.5% (82.3% to 90.9%)) had 4.67 (3.61 to 6.03) and 6.46 (5.20 to 8.02) times higher risk of HPV infection than their HIV negative counterparts.ConclusionHPV infection is prevalent in China, particularly in Central China, in comparison with the global level and neighbouring countries. Targeted HPV vaccination for women, MSM and PLHIV and scale-up of cervical screening for women are priorities in curbing the HPV epidemic in China.

Sinonasal Inverted Papilloma

Background: Although the role of human papillomavirus (HPV) in sinonasal inverted papilloma (SNIP) has been investigated, the link between HPV infection and SNIP recurrence remains controversial. This meta-analysis aimed to investigate the association between HPV infection and recurrence of SNIP. Methods: The PubMed, Web of Science, Google Scholar, and Cochrane Library databases were searched (until 16 June 2021) to collect all relevant articles. The pooled odds ratio (OR) with 95% confidence interval (CI) was calculated using the fixed effects model. In addition, subgroup analysis, assessment of publication bias, and sensitivity analyses were performed. Results: Fourteen eligible articles, including 592 patients with SNIP, were included in this study. Pooled analysis revealed that HPV-positive cases exhibited a significantly higher OR of tumour recurrence than HPV-negative counterparts). A significant association between HPV infection and tumour recurrence remained stable in subgroup analyses according to the publication year of the studies. Conclusions: Our meta-analysis demonstrates that HPV infection is significantly associated with the recurrence of SNIP, suggesting the pathological role of HPV in SNIP. These results suggest that HPV infection should be considered in the management of SNIP.

ObjectivePrevious studies confirmed that high-risk human papillomavirus (HR-HPV) infection is a risk factor of cervical cancer, and the infection was associated with significantly reduced miR-34a expression during carcinogenesis. However, the downstream targets of miR-34a and their roles are still not well understood. This study explored the regulative role of miR-34a on E2F3 and survivin expression and the viability and invasion of HPV-positive cervical cancer cells.MethodsMiR-34a and survivin expression in 56 cases of HR-HPV–positive patients, 28 cases of HR-HPV–negative patients, and 28 normal cases without HR-HPV infections were measured. Human papillomavirus-18–positive HeLa cervical cancer cells and HPV-16–positive SiHa cells were used to explore the effect of miR-34a on cell viability and invasion. The molecular target of miR-34a was also explored in cervical cancer cells.ResultsThe results showed that miR-34a overexpression could inhibit HPV-positive cancer cell viability, whereas its downregulation promoted cell viability. E2F3 is a direct target of miR-34a in HPV-positive cervical cancer cells. By targeting E2F3, miR-34a could regulate the expression of survivin. Thus, through regulating E2F3 and survivin, miR-34a could reduce the viability and invasion of HPV-positive cervical cancer cells.ConclusionsThis study confirmed a novel miR-34a–E2F3–survivin axis in the tumor suppressor role of miR-34a in cervical cancer.

Persistent high-risk human papillomavirus (hrHPV) infection is the highest risk to cervical cancer which is the fourth most common cancer in women worldwide. A growing body of literatures demonstrate the role of cervicovaginal microbiome (CVM) in hrHPV susceptibility and clearance, suggesting the promise of CVM-targeted interventions in protecting against or eliminating HPV infection. Nevertheless, the CVM-HPV-host interactions are largely unknown. In this review, we summarize imbalanced CVM in HPV-positive women, with or without cervical diseases, and the progress of exploring CVM resources in HPV clearance. In addition, microbe- and host-microbe interactions in HPV infection and elimination are reviewed to understand the role of CVM in remission of HPV infection. Lastly, the feasibility of CVM-modulated and -derived products in promoting HPV clearance is discussed. Information in this article will provide valuable reference for researchers interested in cervical cancer prevention and therapy.

The Impact

An etiological role of high risk human papillomavirus (HPV) in the development of cervical cancer has been well established. Hence, attention of researchers has been focused on the role of HPV in pathogenesis of other malignancies, such as head and neck cancers. An analysis of epidemiological data on the prevalence of HPV infection among healthy people and patients with precancerous lesions and/or cancer is an important step in understanding the role of HPV in head and neck carcinogenesis. More and more data demonstrate the impact of HPV infection on disease outcome. HPV­positive patients have been shown to have better responses to radiotherapy and better overall and disease­free survival than HPV­negative patients. This review presents data of the metaanalysis based on a large number of original studies on HPV prevalence in patients with precancerous lesions and in patients with oral, oropharyngeal and laryngeal cancers as well as findings on the impact of HPV infection on survival of these patients.

Given that only a small percentage of human papillomavirus (HPV)-positive women develop cancer, HPV is necessary but insufficient for carcinogenesis. Mucosally transmitted viral cofactors appear to contribute to HPV-related cervical cancer, such as Epstein-Barr virus (EBV), but previous studies have shown inconsistent outcomes. The exact role of EBV in cervical cancer remains unclear, and more studies are needed to determine its involvement. In this study, we describe the prevalence of EBV and HPV coinfection in HIV-positive women and explore how abnormal host immune status induced by viral coinfections modulates epithelial gene expression. We found a significant correlation between EBV-HPV coinfection and the incidence of high-grade cervical intraepithelial neoplasia (CIN2+). RNA sequencing indicated that CIN tissues coinfected with EBV and HPV led to significant changes in the gene expression of epithelial differentiation and development compared to normal tissues with HPV infection alone. In particular, several differentially expressed genes (DEGs) are closely associated with cancer, such as CACNG4, which was confirmed to be upregulated at both the mRNA and protein levels. Therefore, these findings provide some evidence that EBV may act as a cofactor or mediator in HPV-related cervical cancer. Specific genes or proteins, such as CACNG4, may serve as biomarkers that can risk stratify patients based on pathological changes in the cervix.

There are more supports for the view that human papillomavirus (HPV) infection might be an etiological factor in the development of cervical cancer when the association of persistent condylomata is considered. Biopsies from 318 cases with squamous cell carcinoma of uterine cervix, 48 with cervical and vulvar condylomata, 14 with cervical intraepithelial neoplasia (CIN), 34 with chronic cervicitis and 24 normal cervical epithelium were collected from 5 geographic regions of China with different cervical cancer mortalities. All specimens were prepared for Dot blot, Southern blot and in situ DNA-DNA hybridizations by using HPV-11, 16, 18 DNA labelled with 32P and 3H as probes to detect viral homologous sequences in samples. Among them, 32 cases with cervical cancer, 27 with condyloma and 10 normal cervical epitheliums were randomly chosen for comparative EM observation. The results showed that: 1), 192 out of 318 (60.4%) cases of cervical cancer were positive for HPV-16 DNA probe (Table I)

Background: Cervical cancer induced by infection with human papillomavirus (HPV) remains a leading cause of mortality for women worldwide although preventive vaccines and early diagnosis have reduced morbidity and mortality. Advanced cervical cancer can only be treated with either chemotherapy or radiotherapy but outcomes are poor. The median survival for advanced cervical cancer patients is only 16.8 months. Methods: We undertook a structural search of peer-reviewed published studies based on 1). Characteristics of programmed cell death ligand-1/programmed cell death-1(PD-L1/PD-1) expression in cervical cancer and upstream regulatory signals of PD-L1/PD-1 expression, 2). The role of the PD-L1/PD-1 axis in cervical carcinogenesis induced by HPV infection and 3). Whether the PD-L1/PD-1 axis has emerged as a potential target for cervical cancer therapies. Results: One hundred and twenty-six published papers were included in the review, demonstrating that expression of PD-L1/PD-1 is associated with HPV-caused cancer, especially with HPV 16 and 18 which account for approximately 70% of cervical cancer cases. HPV E5/E6/E7 oncogenes activate multiple signaling pathways including PI3K/AKT, MAPK, hypoxia-inducible factor 1α, STAT3/NF-kB and MicroRNAs, which regulate PD-L1/PD-1 axis to promote HPV-induced cervical carcinogenesis. The PD-L1/PD-1 axis plays a crucial role in immune escape of cervical cancer through inhibition of host immune response. creating an "immune-privileged" site for initial viral infection and subsequent adaptive immune resistance, which provides a rationale for therapeutic blockade of this axis in HPV-positive cancers. Currently, Phase I/II clinical trials evaluating the effects of PD-L1/PD-1 targeted therapies are in progress for cervical carcinoma, which provide an important opportunity for the application of anti-PD-L1/anti-PD-1 antibodies in cervical cancer treatment. Conclusion: Recent research developments have led to an entirely new class of drugs using antibodies against the PD-L1/PD-1 thus promoting the body’s immune system to fight the cancer. The expression and roles of the PD-L1/ PD-1 axis in the progression of cervical cancer provide great potential for using PD-L1/PD-1 antibodies as a targeted cancer therapy.
