Human papillomavirus and ovarian cancer (review of literature and meta-analysis). INFECTION GENETICS AND EVOLUTION 2021; 95:105086. [PMID: 34536579 DOI: 10.1016/j.meegid.2021.105086] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/13/2020] [Revised: 09/09/2021] [Accepted: 09/13/2021] [Indexed: 01/05/2023]
Abstract
Many factors are involved in carcinogenesis of the ovary, such human genetic and physiological characteristics as lifestyle, existing diseases of the reproductive system, and, as suggested, the human papillomavirus (HPV). It is well known that the human papillomavirus virus of high carcinogenic risk (HCR) plays a crucial role in the onset and development of cervical cancer, as well as cases of HPV positive breast cancer and endometrial cancer. The data on the presence of HPV in ovarian cancer are ambiguous: the researchers claim that there is no complete effect of the virus on the development of this type of cancer, and the detection of HPV in 60-80% of tumors. In this regard, there is a need to systematize the currently available research results on this controversial issue and conduct a meta-analysis of the association of HPV infection with the risk of ovarian cancer.

Prevalence of human papillomavirus detection in ovarian cancer: a meta-analysis. Eur J Clin Microbiol Infect Dis 2021; 40:1791-1802. [PMID: 34086102 PMCID: PMC8346400 DOI: 10.1007/s10096-021-04282-7] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2021] [Accepted: 05/26/2021] [Indexed: 12/13/2022]
Abstract
We conducted a meta-analysis of published data to update and estimate the prevalence of HPV in ovarian cancer. A comprehensive literature search was performed according to the PRISMA guidelines. Eligible articles published from 1989 until 2020 by searching Web of Sciences, Pubmed, Embase, and the Cochrane Library Central databases were gathered. A pooled estimation of HPV prevalence with a 95% confidence interval (CI) was calculated based on a random effect model. Quantitative assessment of heterogeneity was explored using Cochrane test and I2. Additionally, publication bias, sensitivity, meta-regression, and subgroup analyses were also performed. Twenty-nine studies involving 2280 patients with ovarian cancer were included. The statistical heterogeneity was high (I2 = 88%, P<0.0001). The pooled prevalence of HPV in ovarian cancer cases was 15.9% (95% CI, 11–22). In subgroup analyses, the highest prevalence of HPV was reported by studies from Asia (30.9%; 95% CI, 20–44) and Eastern Europe (29.3%; 95% CI, 4.4–78). Furthermore, the most frequently detected HPV genotype was HPV16 (54%; 95% CI, 27.9–55), followed by HPV18 (23.2%; 95% CI, 18.8–28.2). Our meta-analysis suggests a great difference in the prevalence of HPV detected in ovarian cancer by different studies, which is not seen in strongly HPV-associated cancers such as cervical cancer. However, the prevalence varied markedly by geographic region. Considering the substantial heterogeneity found, more studies with control groups and precise assays measuring HPV mRNA expression are needed to further evaluate the link and causative aetiology between HPV and ovarian cancer.

Human papillomavirus infection: Is it associated with epithelial ovarian cancer? Indian J Med Microbiol 2021; 39:311-314. [PMID: 34016470 DOI: 10.1016/j.ijmmb.2021.05.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2020] [Revised: 03/05/2021] [Accepted: 05/01/2021] [Indexed: 11/28/2022]
Abstract
PURPOSE Human papillomavirus (HPV), the causative agent of cervical cancer, is associated with several other epithelial malignancies. Previous reports on HPV infection and its association with ovarian cancer are highly contradicting. Reports on HPV association with ovarian cancer in Indian women are also rare. Hence, the purpose of this study was to screen women with serous epithelial ovarian cancer for possible HPV infection. METHODS Tumor samples, collected at the time of surgery from 88 women with serous epithelial ovarian cancer were screened using a specific and sensitive PCR. The PCR results were confirmed with Southern blotting using HPV genome-specific probes, both of high-risk HPV type 16 and 18 and low-risk HPV type 6 and 11. All the samples were again tested for another 14 high-risk HPV genotypes with a commercially available qRT-PCR. RESULTS All the samples screened and confirmed by various tests did not show presence of either low-risk or high-risk HPV DNA, indicating the absence of HPV infections in these ovarian cancer tissues. CONCLUSIONS The present study shows that HPV infection may not be associated with epithelial ovarian cancer. The result of the current investigation strongly supports the results of earlier research that, HPV is not associated with ovarian cancer.

The potential role of infectious agents and pelvic inflammatory disease in ovarian carcinogenesis. Infect Agent Cancer 2017; 12:25. [PMID: 28529540 PMCID: PMC5437405 DOI: 10.1186/s13027-017-0134-9] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2017] [Accepted: 04/26/2017] [Indexed: 12/27/2022] Open
Abstract
Background The etiological cause of ovarian cancer is poorly understood. It has been theorized that bacterial or viral infection as well as pelvic inflammatory disease could play a role in ovarian carcinogenesis. Aim To review the literature on studies examining the association between ovarian cancer and bacterial or viral infection or pelvic inflammatory disease. Methods Database search through MEDLINE, applying the medical subject headings: “Ovarian neoplasms”, AND “Chlamydia infections”, “Neisseria gonorrhoeae”, “Mycoplasma genitalium”, “Papillomaviridae”, or “pelvic inflammatory disease”. Corresponding searches were performed in EMBASE, and Web of Science. The literature search identified 935 articles of which 40 were eligible for inclusion in this review. Results Seven studies examined the association between bacterial infection and ovarian cancer. A single study found a significant association between chlamydial infection and ovarian cancer, while another study identified Mycoplasma genitalium in a large proportion of ovarian cancer cases. The remaining studies found no association. Human papillomavirus detection rates varied from 0 to 67% and were generally higher in the Asian studies than in studies from Western countries. Cytomegalovirus was the only other virus to be detected and was found in 50% of cases in a case-control study. The association between ovarian cancer and pelvic inflammatory disease was examined in seven epidemiological studies, two of which, reported a statistically significant association. Conclusions Data indicate a potential association between pelvic inflammatory disease and ovarian cancer. An association between ovarian cancer and high-risk human papillomavirus genotypes may exist in Asia, whereas an association in Western countries seems unlikely due to the low reported prevalence. Potential carcinogenic bacteria were found, but results were inconsistent, and further research is warranted.

High-risk HPV is not associated with epithelial ovarian cancer in a Caucasian population. Infect Agent Cancer 2016; 11:39. [PMID: 27418945 PMCID: PMC4944309 DOI: 10.1186/s13027-016-0087-4] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2016] [Accepted: 06/23/2016] [Indexed: 02/03/2023] Open
Abstract
Background High-risk human papillomavirus (HPV) has been suspected to play a role in the carcinogenesis of epithelial ovarian cancer (EOC). However, results from previous studies are conflicting. In most of these studies, the number of tissue samples was small. The current study was therefore undertaken to examine the prevalence of high-risk HPV DNA in EOC in a large series of patients. Method Formalin-fixed, paraffin-imbedded tumor tissue samples from 198 cases consecutively included in the Danish Pelvic Mass Study were analyzed. The material included 163 serous adenocarcinomas, 15 endometrioid adenocarcinomas, 11 mucinous adenocarcinomas and nine clear-cell carcinomas. Genotyping for high-risk HPV DNA was performed by real-time Polymerase chain reaction (PCR) using an in-house TaqMan singleplex assay targeting the E6/E7 region of the HPV 16 and 18 genomes. Additionally, 20 random samples without HPV 16 and/or 18 infections were reanalyzed for HPV subtypes 31, 33, 35, 39, 45, 51 and 52. Results The quality criteria were fulfilled in 191 samples. HPV 18 DNA was detected in one sample only, while the rest tested negative. The subgroup analysis for seven additional high-risk HPV subtypes was also negative. Conclusions Only one in 191 samples was positive for HPV DNA. We therefore conclude that high risk HPV is unlikely to be associated with EOC in a Caucasian population. Future studies should focus on other microorganisms as possible etiological factors in EOC carcinogenesis.

Prevalence of human papillomavirus in epithelial ovarian cancer tissue. A meta-analysis of observational studies. Acta Obstet Gynecol Scand 2013; 93:6-19. [PMID: 24033121 DOI: 10.1111/aogs.12254] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2013] [Accepted: 08/25/2013] [Indexed: 11/30/2022]
Abstract
OBJECTIVE The role of human papillomavirus (HPV) in the pathogenesis of ovarian cancer is controversial, and conflicting results have been published. We conducted a systematic review and meta-analysis to estimate the prevalence of HPV in epithelial ovarian cancer tissue. MATERIAL AND METHODS Observational studies published until 4 March 2013 were identified in PubMed and Embase. We adhered to MOOSE guidelines and included 22 studies (case-control, cross-sectional studies). A pooled estimate of the HPV prevalence with corresponding 95% confidence interval (CI) was calculated based on a random effect model. In a meta-regression analysis we examined the contribution of different factors to heterogeneity. Furthermore, publication bias was evaluated. RESULTS The pooled HPV prevalence in ovarian cancer tissue was 15.5%, but wide variation was found (0-66.7%). After stratification by geographical region, publication year, tissue type and method of HPV detection, we found that the prevalence of HPV varied most markedly by geographical area, the prevalence being 45.6% (95% CI, 31.0-60.3) in Asia, 18.5% (95% CI, 8.5-28.6) in Eastern Europe, 1.1% (95% CI, -1.6 to 3.8) in Western Europe and zero in North America. A meta-regression analysis revealed that the difference between geographical regions could not be explained by HPV detection method or type of tissue. CONCLUSIONS Great geographical variation exists in HPV prevalence in ovarian cancer tissue, which is not explained by different HPV detection methods. The results suggest that HPV is unlikely to play an important role in Western European and American women, but cannot reject a role of HPV in other populations.

Abstract
ObjectiveWe performed a systematic review and a meta-analysis to estimate the prevalence of human papillomavirus (HPV) in ovarian cancer.MethodsA comprehensive search of the Cochrane Library, MEDLINE, CANCERLIT, LILACS, Grey literature and EMBASE was performed for articles published from January 1990 to March 2012. The following MeSH (Medical Subject Headings) terms were searched: “ovarian tumor” or “ovarian cancers” and “HPV” or “human papillomavirus.” Included were case-control and cross-sectional studies, prospective or retrospective, that evaluated clinical ovarian cancer and provided a clear description of the use of in situ hybridization, Southern blot hybridization, and polymerase chain reaction. The statistical analysis was performed using REVMAN 5.0.ResultsIn total, 24 primary studies were included in this meta-analysis. Studies from 11 countries on 3 continents contained data on HPV and ovarian cancer, including 889 subjects. Overall, the HPV prevalence in patients with ovarian cancer was 17.5 (95% confidence interval [CI], 15.0%–20.0%). Human papillomavirus prevalence ranged from 4.0% (95% CI, 1.7%–6.3%) in Europe to 31.4% (95% CI, 26.9%–35.9%) in Asia. An aggregate of 4 case-control studies from Asia showed an odds ratio of 2.48 (95% CI, 0.64–9.57).ConclusionsWe found a high prevalence of HPV-positive DNA in ovarian cancer cases, but the role of HPV in ovarian cancer remains inconclusive. Further studies are needed to control case to answer this question.

Abstract
OBJECTIVE We sought to analyze the presence of the microorganisms Chlamydia trachomatis, Mycoplasma genitalium, Neisseria gonorrhoeae, human papillomavirus (HPV), and the polyomaviruses BK virus (BKV) and JC virus (JCV) in ovarian tissues of women with ovarian carcinomas, borderline tumors, and benign conditions. STUDY DESIGN Ovarian tissue, snap-frozen and stored at -80 degrees C, from 186 women with benign conditions, borderline tumors, and epithelial ovarian cancer, as well as tissue from the contralateral ovary of 126 of these women, were analyzed regarding presence of C trachomatis and N gonorrhoeae (transcription mediated amplification), M genitalium (real-time polymerase chain reaction [PCR]), HPV (PCR), and BKV and JCV (PCR). RESULTS All the tissue samples studied were found negative for the microorganisms analyzed. CONCLUSION C trachomatis, M genitalium, N gonorrhoeae, HPV, and the polyomaviruses BKV and JCV are not detectable in ovarian tissues either from women with benign conditions and borderline tumors or from women with ovarian cancer.

Abstract
Distinction of primary ovarian epithelial tumors from metastatic adenocarcinomas is challenging for tumors exhibiting mucinous, endometrioid, or mixed endometrioid/mucinous differentiation. Metastatic carcinomas with these types of differentiation can be derived from several sites, including the gastrointestinal tract and the uterus. Most endocervical adenocarcinomas exhibit mucinous and/or endometrioid differentiation; they infrequently metastasize to the ovaries but may simulate primary ovarian tumors [both atypical proliferative (borderline) and carcinoma]. Most are high-risk human papillomavirus (HPV)-related and demonstrate diffuse p16 over-expression due to complex molecular mechanisms by which high-risk HPV transforming proteins interact with cell cycle regulatory proteins. The performance of this expression pattern for identifying metastatic endocervical adenocarcinomas in the ovaries among primary ovarian tumors and other metastatic adenocarcinomas having mucinous and/or endometrioid/endometrioidlike differentiation has not been evaluated. Immunohistochemical expression of p16 was assessed in 195 tumors, including 98 primary ovarian tumors (51 mucinous, 47 endometrioid, and 4 mixed mucinous-endometrioid tumors), 93 metastatic adenocarcinomas of known primary sites (colorectum: 34, endocervix: 19, pancreaticobiliary tract: 17, appendix: 7, stomach: 5), 11 metastatic adenocarcinomas of unknown origin (7 established as noncervical), and 4 adenocarcinomas of uncertain (primary ovarian vs. metastatic) origin. The HPV status of the endocervical adenocarcinomas was determined by in situ hybridization and polymerase chain reaction (when in situ hybridization was negative). Expression was assessed based on the percentage of moderately to strongly positive cells, estimated to the nearest 10%. Mean and median expression values for HPV-positive endocervical adenocarcinomas (99%, 100%; range 90% to 100%) were substantially higher than those for primary ovarian mucinous (5%, 0%; range 0% to 70%) and endometrioid (20%, 10%; range 0% to 100%) tumors, HPV-unrelated endocervical adenocarcinomas (0%, 0%; range 0% to 60%), metastatic adenocarcinomas of unknown origin (11%, 0%; range 0% to 30%), and adenocarcinomas of uncertain (primary ovarian vs. metastatic) origin (40%, 35%; range 0% to 90%); only the 15 HPV-positive endocervical adenocarcinomas and 6 other tumors had values of 80% or greater. Diffuse (>75% positive tumor cells) moderate to strong p16 expression is a sensitive (100%) and specific (97%) marker for identifying HPV-related endocervical adenocarcinomas metastatic to the ovary among the primary ovarian tumors and metastatic adenocarcinomas from other sites that are in the differential diagnosis of ovarian tumors having mucinous and/or endometrioid/endometrioidlike differentiation. p16 is useful as part of a panel of immunohistochemical markers for distinguishing primary ovarian tumors from metastases and, when diffusely positive, can suggest the cervix as a potential primary site for metastatic adenocarcinomas of unknown origin.

Abstract
OBJECTIVE To evaluate the role of human papillomavirus (HPV) types 6, 11, 16, 18, 31 or 33 infection in primary fallopian tube carcinoma (PFTC). DESIGN A retrospective case-control study. SETTING Department of Obstetrics and Gynaecology, Helsinki University Hospital, Finland. POPULATION Seventy-eight consecutive women with PFTC diagnosed between 1985 and 2000 were studied. For each case, two healthy controls were selected. METHODS Serum immunoglobulin G antibodies to HPV types 6, 11, 16, 18, 31 and 33 were measured from women with PFTC and their healthy controls. MAIN OUTCOME MEASURES Analysis of HPV 6, 11, 18, 31 and 33 seropositivity among women with PFTC and controls. RESULTS Seropositivity rates of non-oncogenic or oncogenic HPV types did not differ between cases and controls, odds ratios being 1.04-1.30 for oncogenic HPVs and 1.08-1.19 for non-oncogenic HPVs, similarly. We did not find any multiplicative joint effect in PFTC by antibodies to more than one oncogenic HPV type; neither did we find any antagonistic effect among women with antibodies to non-oncogenic and oncogenic HPV types. CONCLUSIONS Our results do not suggest any link between PFTC and serological evidence for HPV infection.

Abstract
AIM The role of human papillomavirus (HPV) infection in ovarian tumorigenesis is uncertain. The objective of this study was to screen a collection of ovarian tumors for the presence of high-risk oncogenic HPV types 16, 18 and 33. METHODS Twenty benign and malignant ovarian tumors were obtained from women undergoing pelvic surgery at a regional comprehensive cancer institution in North America. DNA was isolated from the snap-frozen tumors, and commercial polymerase chain reaction (PCR) detection sets were used to analyze the tumor DNA samples for the presence of DNA from HPV types 16, 18 and 33. RESULTS The DNA from HPV types 16, 18 and 33 was not detected in any of the ovarian tumors. CONCLUSIONS Our findings do not support an association between infection with HPV types 16, 18 and 33 and ovarian neoplasia in this patient population.

Abstract
Human papillomavirus is the causal factor for cervical cancer. However, the role of HPV infection in ovarian cancer is unclear. This study aimed to determine the presence of human papillomavirus-16 (HPV-16) in ovarian cancer tissues. Archived human ovarian cancer tissues (N=54 cases, 50 are epithelial cancer, four are nonepithelial cancer) embedded in paraffin blocks were used. Controls are 30 nonmalignant ovarian tissue blocks. In situ hybridisation (ISH) and immunohistochemistry (IHC) were used to detect the presence of HPV-16 and p53 expression. In all, 52 or 36% of the epithelial ovarian tumours detected by ISH or IHC, respectively, were HPV-16 E6 positive. In contrast, only 6.7% of normal ovarian tissues were HPV-16 positive proved by ISH. Human papillomavirus-16 infection was significantly higher in cancer tissues compared to controls with an odds ratio of 16.7 (95% confidence interval [CI]=3.2-71.4, P<0.01). No significant correlation between HPV-16 infection and histological types of cancer was found (P>0.05). p53 gene expression was detected in 42% epithelial ovarian cancers. No correlation between p53 expression and HPV-16 infection was found. The results showed the presence of HPV-16 E6 in ovarian carcinoma, suggesting that HPV infection might play a role in ovarian carcinogenesis.

Abstract
OBJECTIVE The aim of this study was to determine the prevalence of high-risk oncogenic human papillomaviruses (HPVs) in malignant lesions from Hong Kong Chinese women with carcinomas of the upper genital tract. METHODS The presence of high-risk HPVs in 55 cases of endometrial adenocarcinomas and 60 cases of primary epithelial ovarian cancers was detected by polymerase chain reaction (PCR) using consensus primers complementary to late 1 (L1) gene of the genital HPVs. Amplified PCR products were verified and typed by Southern blot analysis using (32)P-labeled DNA probes prepared from cloned HPV-16 and -18 plasmids. To confirm the presence of high-risk HPV types in the tumor tissues, PCR amplification using HPV type 16- and 18-specific primers for part of the E6 gene were also carried out. RESULTS While HPV-18 was not detected, HPV-16 DNA sequences were identified in 5 (9.1%) of the 55 studied endometrial carcinoma samples. Of the 5 HPV-16-positive cases, there were 4 stage I, and 1 stage II endometrial cancer. In addition, 6 (10%) of the 60 epithelial ovarian carcinomas were positive for high-risk HPVs, which included 5 cases with HPV-16 and 1 case with HPV-18. Clinical staging revealed that 5 of the 6 HPV-positive cases were stage I and the remaining case was stage III ovarian cancer. Histology of the 6 HPV-positive cases showed that there were 1 case of clear-cell adenocarcinoma, 1 case of mucinous cystadenocarcinoma, and 4 cases of mucinous tumor of borderline malignancy. No other HPV types were detected. CONCLUSION High-risk HPV was detected in approximately 10% of the tumor samples from women with upper genital tract carcinomas. As compared to the high positive rate of HPV infections in cervical cancer, it appears that HPV infection plays a relatively minor role in the pathogenesis of endometrial and ovarian carcinomas.
