HPV-Associated Breast Cancer: Myth or Fact? Pathogens 2022; 11:pathogens11121510.

Abstract
Some estimates place the proportion of human malignancies attributable to viruses at between 15 and 20 percent. Viruses including the human papillomavirus are considered an interesting but controversial etiological risk factor for breast cancer. HPV infection is anticipated to be an early trigger in breast cancer carcinogenesis, followed by cumulative alterations over time ("hit and run" mechanism) through synergy with other environmental factors. The association between HPV and breast cancer has not yet been verified. There are very conflicting data on the presence of HPV DNA in breast cancer samples, and we lack a clarified, exact mode of HPV transmission to the breast. In our review article we analyzed the up-to-date knowledge about the association of HPV and breast cancer. Furthermore, we summarized the available original research published since 2010. In conclusion, the complexity and inconsistency of the available results together with the relatively low prevalence of HPV infection requires extensive research with much larger studies and exact and unified diagnostic methods are required to better understand the role of the HPV in breast carcinogenesis.

Identification of human MHC-I HPV18 E6/E7-specific CD8 + T cell epitopes and generation of an HPV18 E6/E7-expressing adenosquamous carcinoma in HLA-A2 transgenic mice. J Biomed Sci 2022; 29:80. [PMID: 36224625 PMCID: PMC9554842 DOI: 10.1186/s12929-022-00864-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2022] [Accepted: 09/28/2022] [Indexed: 01/21/2023] Open
Abstract
BACKGROUND Human Papillomavirus type 18 (HPV18) is a high-risk HPV that is commonly associated with cervical cancer. HPV18 oncogenes E6 and E7 are associated with the malignant transformation of cells, thus the identification of human leukocyte antigen (HLA)-restricted E6/E7 peptide-specific CD8 + T cell epitopes and the creation of a HPV18 E6/E7 expressing cervicovaginal tumor in HLA-A2 transgenic mice will be significant for vaccine development. METHODS In the below study, we characterized various human HLA class I-restricted HPV18 E6 and E7-specific CD8 + T cells mediated immune responses in HLA class I transgenic mice using DNA vaccines encoding HPV18E6 and HPV18E7. We then confirmed HLA-restricted E6/E7 specific CD8 + T cell epitopes using splenocytes from vaccinated mice stimulated with HPV18E6/E7 peptides. Furthermore, we used oncogenic DNA plasmids encoding HPV18E7E6(delD70), luciferase, cMyc, and AKT to create a spontaneous cervicovaginal carcinoma model in HLA-A2 transgenic mice. RESULTS Therapeutic HPV18 E7 DNA vaccination did not elicit any significant CD8 + T cell response in HLA-A1, HLA-24, HLA-B7, HLA-B44 transgenic or wild type C57BL/6 mice, but it did generate a strong HLA-A2 and HLA-A11 restricted HPV18E7-specific CD8 + T cell immune response. We found that a single deletion of aspartic acid (D) at location 70 in HPV18E6 DNA abolishes the presentation of HPV18 E6 peptide (aa67-75) by murine MHC class I. We found that the DNA vaccine with this mutant HPV18 E6 generated E6-specific CD8 + T cells in HLA-A2. HLA-A11, HLA-A24 and HLA-b40 transgenic mice. Of note, HLA-A2 restricted, HPV18 E7 peptide (aa7-15)- and HPV18 E6 peptide (aa97-105)-specific epitopes are endogenously processed by HPV18 positive Hela-AAD (HLA-A*0201/Dd) cells. Finally, we found that injection of DNA plasmids encoding HPV18E7E6(delD70), AKT, cMyc, and SB100 can result in the development of adenosquamous carcinoma in the cervicovaginal tract of HLA-A2 transgenic mice. CONCLUSIONS We characterized various human HLA class I-restricted HPV18 E6/E7 peptide specific CD8 + T cell epitopes in human HLA class I transgenic mice. We demonstrated that HPV18 positive Hela cells expressing chimeric HLA-A2 (AAD) do present both HLA-A2-restricted HPV18 E7 (aa7-15)- and HPV18 E6 (aa97-105)-specific CD8 + T cell epitopes. A mutant HPV18E6 that had a single deletion at location 70 obliterates the E6 presentation by murine MHC class I and remains oncogenic. The identification of these human MHC restricted HPV antigen specific epitopes as well as the HPV18E6/E7 expressing adenosquamous cell carcinoma model may have significant future translational potential.

Abstract
BACKGROUND Although the association of human papillomavirus (HPV) with many cancers is well established, the involvement of HPV in breast cancer remains controversial. The purpose of this study is to perform a comprehensive review of the results and methods used to demonstrate that HPV markers are present in human breast cancer, and how well these studies fulfil the criteria for proving the viral etiology of a cancer. STUDY DESIGN We conducted a search for molecular studies published until November 2016 that relate human breast cancer to HPV. RESULTS Forty-three original molecular studies were found, some of which compared cases to nonneoplastic controls. Some investigations did not identify HPV in mammary tissue, but others identified it with different frequencies of positivity, varying between 1.2 and 86%. In most case-control studies (21/24 studies), positivity in cases was found to be higher than in controls, but odds ratios and confidence intervals were not reported. CONCLUSION The results are controversial. However, they arouse a great interest in the potential participation of HPV in breast carcinogenesis, but rather as an essential cause-effect participant, at least as a co-participant in some cases. The circumstance of HPV positivity in breast cancer can be criticized, but the elements that clearly demonstrate it in a number of cases are also relevant.

Abstract
Our objective was to compare the association between tobacco smoking and chewing and the risk of multiple human papillomavirus (HPV) infections and cervical squamous intraepithelial lesions (SILs) in two populations with different tobacco exposure. We studied 2,162 women from Côte d'Ivoire, West Africa, and 419 women from Finland, Northern Europe, with baseline data on cervical screening, HPV DNA status and smoking and chewing habits. The proportion of women who smoked and/or chewed tobacco was higher in Finland (36.8%) than in Côte d'Ivoire (3.7%), where tobacco chewing (2.6%) was more common than tobacco smoking (1.4%). Having multiple HPV infections was common in HPV16 and/or 18-infected women (60.4% in Finland and 47.2% in Côte d'Ivoire). There was no increased risk of multiple HPV infections among tobacco consumers. We found that women >or=30 years of age exposed to tobacco through smoking in Finland (OR: 2.2, 95% CI: 0.5-8.7) and chewing in Côte d'Ivoire (OR: 5.5, 95% CI: 2.1-14) had a moderately or highly increased risk of high-grade SIL, respectively. In the latter, the risk was statistically significant. Our findings emphasize the need for health initiatives targeted to prevent tobacco smoking or chewing among women especially in less industrialized countries.

Abstract
Many studies have suggested that human papillomavirus (HPV) infection plays an important role in the carcinogenesis of the cervical adenocarcinoma. However, the prevalence of HPV infection in cervical adenocarcinoma and adenosquamous carcinoma varies among the studies. Cervical adenocarcinoma (24 cases) and adenosquamous carcinoma (16 cases), including the underlying non-neoplastic epithelium were examined for HPV-DNA using in situ polymerase chain reaction (PCR), which enabled visualization of the localization on a glass slide. In adenocarcinoma, HPV-DNA was found in 13 cases (54%) and in eight cases in underlying non-neoplastic epithelium, resulting in a total of 21 positive cases (88%). In adenosquamous carcinoma, HPV-DNA was detected in 12 cases (75%) and and the HPV-DNA localization of each component was pure adenocarcinoma, 28.6%; mixed, 54.5%; and pure squamous cell carcinoma, 83.3%. In the underlying non-neoplastic epithelium, HPV-DNA was found more frequently in the squamous epithelium (73.3%) than the cervical glands (6.3%). In conclusion, HPV-DNA was detected in 54% of adenocarcinoma, and the rate was elevated by HPV localization in the underlying non-neoplastic epithelium. HPV infection in the underlying squamous epithelium might be related to the carcinogenesis, even in cervical adenocarcinoma. HPV-DNA localization was different in each component of adenosquamous carcinoma.

Abstract
While HPV 16 variant lineages have been well characterized, the knowledge about HPV 18 variants is limited. In this study, HPV 18 nucleotide variations in the E2 hinge region were characterized by sequence analysis in 47 control and 51 tumor specimens. Fifty of these specimens were randomly selected for sequencing of an LCR-E6 segment and 20 samples representative of LCR-E6 and E2 sequence variants were examined across the L1 region. A total of 2770 nucleotides per HPV 18 variant genome were considered in this study. HPV 18 variant nucleotides were linked among all gene segments analyzed and grouped into three main branches: Asian-American (AA), European (E), and African (Af). These three branches were equally distributed among controls and cases and when stratified by Hispanic and non-Hispanic ethnicities. Among invasive cervical cancer cases, no significant differences in the three HPV variant branches were observed among ethnic groups or when stratified by histopathology (squamous vs. adenocarcinoma). The Af branch showed the greatest nucleotide variability when compared to the HPV 18 reference sequence and was more closely related to HPV 45 than either AA or E branches. Our data also characterize nucleotide and amino acid variations in the L1 capsid gene among HPV 18 variants, which may be relevant to vaccine strategies and subsequent studies of naturally occurring HPV 18 variants. Several novel HPV 18 nucleotide variations were identified in this study.

Abstract
OBJECTIVE Adenocarcinoma of the uterine cervix appears to be increasing in prevalence and it has been suggested that these tumors tend to be less sensitive to radiation therapy and to chemotherapy than squamous carcinomas. In the present study, 29 patients with locally advanced cervical adenocarcinoma (bulky IB-IVB) were treated with neoadjuvant chemotherapy (NAC) using cisplatin, aclacinomycin-A and mitomycin-C, followed by radical surgery or irradiation. METHODS To predict the prognosis and response to the chemotherapy, the expression of apoptosis associated-proteins, p53, p21WAF1/CIP1, Bcl-2 and activated caspase-3 was evaluated for tumor samples by immunohistochemistry. RESULTS Of the analyzed clinicopathological factors, the overexpression of p53 was frequently observed in endocervical-type adenocarcinoma, nonresponders to chemotherapy and the grade 0 histologic effect of the chemotherapy. Positive staining of Bcl-2 was frequently observed in the early stage and had a better prognosis than for patients with the negative staining; however, there was no correlation between responders and nonresponders to chemotherapy. The expression of p21WAF1/CIP1 and caspase-3 was not correlated to the clinicopathological factors. CONCLUSION In this study, the overexpression of p53 was found to be a factor to predict the chemoresistance and positive expression of Bcl-2 indicated as a better prognostic value. For p21WAF1/CIP1 and caspase-3, further analysis is necessary.

Abstract
BACKGROUND The value of DNA image cytometry in the differential diagnosis of endocervical adenocarcinoma was tested on a series of 65 cases of normal endocervical cells (n = 25), inflammatory changes (n = 18), and endocervical adenocarcinoma (n = 22). METHODS The investigation was performed on gynecologic routine smears by using a television image analysis system MIAMED-DNA (Leica, Wetzlar, Germany), combined with an automated Leica Medilux microscope. First, the Papanicolaou stained specimens were rescreened, and the x/y coordinates of at least 150 endocervical nuclei were stored per case by using a scanning program. After restaining according to Feulgen, the epithelial cells were relocalized and the DNA content, and the nuclear area were determined. The DNA content of 25-30 squamous epithelial cells of intermediate type served as an internal standard for the normal diploid value in each case. Various DNA cytometric parameters and the mean nuclear area were calculated. For statistical analysis, the cases of adenocarcinoma (n = 22) were defined as positive, and the cases with normal endocervical epithelium or inflammatory changes (n = 43) were defined as negative. RESULTS The presence of nuclei with a DNA content greater than 9c was observed exclusively in adenocarcinoma (sensitivity, 95.9%; specificity, 100%), indicating that this parameter is suited best for the differentiation between malignant and nonmalignant endocervical epithelium. High sensitivity rates at a specificity level of 100% also were calculated for the 2.5cER (95.5%), the mean ploidy (90.9%), 5cER (90.9%), and the diploid deviation quotient (90.9%). For the 2cDI (86.4%), the entropy (81.8%) and the ploidy imbalance (77.3%) lower values were obtained. CONCLUSIONS DNA single cell cytometry represents a highly relevant tool in the identification of malignant transformation in endocervical lesions that could be used as a complementary diagnostic method in cytologically difficult cases. Investigations on endocervical adenocarcinoma in situ should be performed in the near future.

Abstract
PURPOSE To determine the association between human papillomavirus (HPV) type and prognosis of patients with invasive cervical carcinoma. PATIENTS AND METHODS Patients diagnosed with International Federation of Gynecology and Obstetrics (FIGO) stage IB to IV cervical cancer between 1986 and 1997 while residents of three Washington State counties were included (n = 399). HPV typing was performed on paraffin-embedded tumor tissue using polymerase chain reaction methods. Patients were observed for a median of 50.8 months. Total mortality (TM) and cervical cancer-specific mortality (CCSM) were determined. Hazards ratios (HR) adjusted for age, stage, and histologic type were estimated using multivariable models. RESULTS Eighty-six patients had HPV 18-related tumors and 210 patients had HPV 16-related tumors. Cumulative TM among patients with HPV 18-related tumors and among patients with HPV 16-related tumors were 33.7% and 27.6%, respectively; cumulative CCSM in these two groups were 26.7% and 18.1%, respectively. Compared with patients with HPV 16-related cancers, patients with HPV 18-related cancers were at increased risk for TM (HR(TM), 2.2; 95% confidence interval [CI], 1.3 to 3.6) and CCSM (HR(CCSM), 2.5; 95% CI, 1.4 to 4.4). The HPV18 associations were strongest for patients with FIGO stage IB or IIA disease (HR(TM), 3.1; 95% CI, 2.3 to 4.2; and HR(CCSM), 5.8; 95% CI, 3.9 to 8.7), whereas no associations were observed among patients with FIGO stage IIB to IV disease. Virtually identical associations were found in the subset of patients with squamous cell carcinoma (n = 219). CONCLUSION HPV 18-related cervical carcinomas, particularly those diagnosed at an early stage, are associated with a poor prognosis. Elucidating the mechanism or mechanisms underlying this association could lead to new treatment approaches for patients with invasive cervical carcinoma.

Abstract
OBJECTIVE Patterns of discontinuous deletion of chromosome 4 have been described in histologic variants of lung carcinomas and may represent different "hotspot" targets for gene-environment interactions. Since similar environmental risks exist for cervical cancer, we investigated patterns of discontinuous deletion in two major histologic variants. METHODS Thirteen archival cases of squamous cell cancer (SCCA) and 11 cases of adenocarcinoma (AC) were precisely microdissected. Matched normal and tumor DNA were used for polymerase chain reaction (PCR) based loss of heterozygosity (LOH) analyses using 19 polymorphic markers spanning chromosome 4. Human papillomavirus (HPV) detection was determined by PCR using general and type-specific primers (HPV 16, 18). Differences in LOH between histologic tumor types and chromosomal regions were determined using Fisher's exact test. RESULTS Loss at any chromosome 4 locus occurred in 92% of all tumors studied, with the majority of deletions occurring on the long arm of the chromosome. Four discrete minimal regions of discontinuous deletion (R) were identified. For these regions, LOH frequencies were 76% (R1, 4q34-q35), 48% (R2, 4q25-q26), 36% (R3, 4p15.1-p15.3), and 26% (R4, 4p16). Loss in SCCA predominated at 4q (4q34-q35; 83%) and in AC at 4p (4p15.3; 50%). Overall LOH on the p arm was significant in AC (82%) compared to SCCA (31%) (P = 0.02). HPV detection was similar in SCCA (85%) and AC (73%), and HPV 16/18 subtypes were similarly represented in both histologies. CONCLUSIONS Chromosome 4 deletions are frequent in cervical carcinomas. Different patterns of deletion between SCCA and AC may represent gene regions targeted by different gene-environment interactions in these tumor subtypes.

Abstract
OBJECTIVE To determine the human papillomavirus (HPV) types in cervical adenocarcinoma of patients from Taiwan. METHODS DNA was extracted from fixed tissues and polymerase chain reaction was performed in conjunction with a unique probe, pRSA I, allowing simultaneous detection of HPV types 6, 11, 16, 18, 31 and 33 from amplified HPV DNAs after endonuclease, RsaI, digestion. RESULTS Of 69 tissues examined, 31.9% (22/69) were found to contain HPV DNA. Among 22 HPV-positive specimens, no HPV types 6, 11, 31 and 33 were detected. On the other hand, HPV 16 and HPV 18 were found in 11 (15.9%) and 10 (14.5%) of HPV-positive specimens, respectively. One specimen (1.5%) was found to contain both HPV 16 and 18 DNAs. CONCLUSIONS Our findings support that HPV 18, along with HPV 16, may play a certain role in the adenocarcinoma pathogenesis of the uterine cervix.

Abstract
In the pathogenesis of cervical squamous cell carcinoma, an inverse correlation between human papillomavirus (HPV) infection and mutation of the p53 anti-oncogene has been suggested. Much less is known of a possible correlation in the case of adenocarcinoma of cervix. Twenty-five cervical adenocarcinomas and 7 adenosquamous carcinomas were analyzed for presence of HPV DNA sequences and overexpression of the p53 gene. Polymerase chain reaction revealed that 11 were positive for HPV DNA (34%). Seven were positive for HPV 16 and 5 for HPV 18. A mixed infection with HPV 16 and 18 was observed in 1 case. Patients with HPV-positive carcinoma were significantly younger than those with HPV-negative carcinoma (43 +/- 13.3 years versus 57 +/- 17.4 years, P = 0.01). Immunohistochemical staining showed that p53 was overexpressed in 11 of 32 cases (34%). Overexpression of the p53 gene was found in only 1 of 11 HPV-positive cases (9%) yet was evident in 10 of 21 HPV-negative cases (48%). This inverse association was statistically significant (P < 0.05). Prognostic analysis revealed that HPV-negative adenocarcinomas had a poorer prognosis than HPV-positive cases (P < 0.01) and that tumors with p53 overexpression also had a poorer prognosis than those without such overexpression (P < 0.01). Our observations suggest that HPV-negative or p53-positive adenocarcinomas may be a biologically distinct subset with a poorer prognosis.

Abstract
In an attempt to characterize the molecular alterations of cervical adenocarcinoma, we analyzed 32 paraffin-embedded specimens for the presence of K-ras mutations, p53 overexpression, p16 and Rb protein expression, and the presence of HPV 16 and 18 DNA. Overall 25/32 (78%) of the tumors displayed an abnormality in at least one of these analyses. K-ras mutations were detected by PCR amplification and RFLP analysis in 3 tumors, including 2 at codon 12 and 1 at codon 61. p53 overexpression determined by immunohistochemistry was demonstrated with > 80% of tumor nuclei staining in 4 cases, 10-15% of nuclei staining in 3 cases, and < 1% of nuclei staining in 5 cases. The pattern of staining was diffuse in 6 cases, focal in 1 case, and scattered in 5 cases. Analysis of p16 protein expression in 23 specimens revealed 1 tumor with abnormal staining, while Rb protein expression was determined to be normal in all 25 tumors tested. HPV DNA, detected by PCR with type-specific primers, was found in 16 tumors (50%), including 7 (22%) with HPV 16 and 9 (28%) with HPV 18. There was no correlation among these abnormalities except that the presence of HPV and strong p53 overexpression (> 80% tumor nuclei staining) were mutually exclusive events. Clinical correlation demonstrated that p53 overexpression involving the majority of tumor cell nuclei is characteristic of advanced stage disease, while HPV positivity and activated ras genes are associated with early stage disease.

Abstract
Tumor specimens obtained from 136 patients with primary carcinoma of the uterine cervix were analyzed for the presence of human papillomavirus (HPV) sequences and for mutation of the TP53 gene. Polymerase chain reaction (PCR) showed that 130 of 136 (96%) tumors contained an oncogenic HPV 16 or 18 sequence. HPV 16 was the predominant type in cervical squamous cell carcinomas and HPV 18 was significantly associated with cervical adenocarcinomas (p < 0.05). The more dedifferentiated the primary tumor, the more frequent the HPV 16 infection and the more differentiated, the more frequent the HPV 18 infection (p < 0.05). Two out of 136 (1.5%) tumors demonstrated single-strand conformation polymorphism (SSCP) band shifts. One (positive for HPV 18) had a nonsense mutation of codon 101 in exon 4 from AAA to TAA transversion. Another (positive for L1 consensus primer set) showed a point mutation involving codon 179 in exon 5 changing CAT to CGT transition. The three specimens negative for HPV did not contain TP53 gene mutations. Our data show that mutation of TP53 is infrequent in primary cervical carcinoma and there is no inverse correlation between HPV infection and TP53 gene mutation. Other mechanisms independent of TP53 inactivation may also be implicated in tumorigenesis of the uterine cervix.

Abstract
Inactivation of the wild type p53 protein through complexing of protein synthesized by specific subtypes of human papilloma virus (HPV) or mutation in the p53 gene in considered to play an important role in cervical carcinogenesis. The association between p53 overexpression and the presence of HPV 16 and 18 DNA was assessed in 29 cervical carcinomas, 15 carcinomas of the lower uterine segment and 30 endometrial carcinomas. In 29 cervical carcinomas (21 adenocarcinomas and 8 adenosquamous carcinomas), 7 cases were positive for HPV 16 DNA while 5 were positive for HPV 18 DNA. Nine cases (31%) showed p53 overexpression. An inverse association was seen between the presence of HPV DNA and the p53 overexpression. In 15 carcinomas of the lower uterine segment, one case was positive for HPV 16 DNA while 2 were positive for HPV 18 DNA. Overexpression of p53 was seen in 8 (53%) carcinomas of the lower uterine segment. Two of 3 HPV DNA positive carcinomas of the lower uterine segment revealed p53 overexpression. HPV DNA was not detected in endometrial carcinomas and p53 overexpression was shown in 12 (40%) cases. The association between HPV DNA and p53 overexpression differs among the tumors arising in the cervix, lower uterine segment and endometrium.

Abstract
BACKGROUND It is well recognized that adenocarcinomas and adenosquamous carcinomas of the cervix are frequently associated with human papillomavirus (HPV)-16 or -18. However, few studies have investigated associations between histologic variants of these tumors and specific types of HPV. METHODS Eleven cases of cervical adenosquamous carcinoma with an unusual histologic appearance were characterized using histochemical and immunohistochemical stains. Sections were tested for the presence of HPV DNA using the polymerase chain reaction (PCR) and type specific primers for HPV-16 and -18. Clinical outcome was determined from a chart review. RESULTS All tumors were histologically characterized by the presence of sheets of cohesive cells with prominent cell borders and a vacuolated or clear cytoplasm containing large amounts of glycogen. All tumors had focal gland formation and stained positive with mucicarmine stain. Using PCR, HPV-18 DNA was identified in all cases. The youngest patient was 24 years old and the oldest 74 years (mean, 43 years). Eight (73%) of the 11 patients have developed recurrent disease with a mean follow-up until recurrence of 9.5 months (range, 3-22 months). Seven (64%) of the 11 patients have died of their cervical tumors. Of the five patients with Stage IB disease, three (60%) have died of their cervical tumors. CONCLUSIONS A subset of invasive cervical adenosquamous carcinoma associated with HPV-18 that has a distinctive histologic appearance and an aggressive clinical course is described. The term "clear cell adenosquamous carcinoma" is proposed for this unique variant of invasive cervical carcinoma.

Abstract
Certain human papaillomavirus (HPV) types are major risk factors for the development of cervical neoplasia. The value of HPV DNA testing in the management of patients with disease and in population screening is a subject of controversy. Since the introduction of molecular biology into the HPV field, there have been rapid advances and improvements in HPV diagnosis. The various molecular diagnostic methods for detection of HPV DNA (dot blot hybridization, Southern blot hybridization, in situ hybridization, Hybrid Capture Test, and polymerase chain reaction; PCR) could be selected by taking into consideration some factors such as characteristics of sample, sensitivity of HPV test and expenses. The HPV DNA testing would be a clinically useful diagnostic method, when used in conjunction with the Pap smear in population screening or in conjunction with cytology and colposcopy to identify the women infected with high-risk HPVs or women who had equivocal cervical lesions. Despite the confusion, a multitude of reports demonstrate that HPV DNA testing has the clinical utility, and future investigations should be directed at more accurately delineating its role in human health care.

Abstract
Accumulating evidence highlights the human papillomavirus (HPV) as a risk factor for cervical adenocarcinoma. However, the part played by the HPV in predicting tumor outcome or the increasing frequency of cervical adenocarcinoma is incompletely studied. In a retrospective study the association between HPV status and the clinicopathological characteristics of 77 cases of cervical adenocarcinoma was investigated. The data were then analyzed for temporal differences in HPV status and to identify outcome predictors. Human papillomavirus status was determined by dot blot hybridization using probes for HPV 6, 11, 16, 18, 31, 33, and 35, followed by polymerase chain reaction amplification of the dot blot negative cases. Seven type-specific and consensus HPV primers were used. Human papillomavirus type 16, 18, or 33 was present in 53 (70%) cases. Human papillomavirus status did not correlate with disease outcome or any clinicopathological variable, except that tumors presenting in and after 1981 were more frequently HPV positive than those presenting before 1981 (P = .014). In a multivariate analysis only clinical stage at presentation was predictive of disease outcome. Because temporal differences in clinicopathological characteristics were not identified, the increasing frequency of cervical adenocarcinoma may relate to a more important oncogenic role for the HPV in tumors presenting after 1980.

Abstract
The evidence implicating specific HPV types in the aetiology of cervical cancer is now strong enough to establish a causative role. HPV infection of the cervix affects the developing immature metaplastic cells of the transformation zone. Cervical neoplasia can be viewed as the interaction of high risk papillomavirus and immature metaplastic epithelium. Once maturity is reached, there is minimal risk of subsequent development of cervical squamous neoplasia. Exposure to HPV is an extremely common event, especially in young sexually active women. Yet, despite frequent HPV exposure at that phase of life in which the cervical transformation zone is at its most vulnerable, established expressed disease is relatively uncommon. Most studies in which the natural history of CIN is not altered by cervical biopsy reveal a progression rate from low to high grade CIN of less than one third. Where viral type is taken into account, however, the progression rate from normal but high risk HPV-infected cervical epithelium to CIN 2 or 3 is higher. Despite this, most cervical abnormalities will not transform into invasive cancer, even if left untreated. The variance between the high rate of HPV infection, the intermediate rate of CIN and the relatively low rate of cervical cancer establishes a stepwise gradient of disease of increasing severity with decreasing prevalence. In an immunocompetent host, HPV infection alone does not appear to be sufficient to induce the step from high grade CIN to invasion. Epidemiological studies indicating that HPV infection with oncogenic viral types is far more common than cervical neoplasia suggest the necessity of cofactors in cervical carcinogenesis. The long time-lag between initial infection and eventual malignant conversion suggests that random events may be necessary for such conversion, and the spontaneous regression of many primary lesions suggests that most patients are not exposed to these random events. Potential cofactors include cigarette smoking, hormonal effects of oral contraceptives and pregnancy, dietary deficiencies, immunosuppression and chronic inflammation. In those women who develop cervical cancer, malignant progression is rarely rapid, more commonly taking many years or decades. Malignant progression has been documented in patients who presented initially with only low grade HPV-induced atypia. On the other hand, progression may be a misnomer, as 'apparent' progression may really represent adjacent 'de novo' development of higher grade CIN. Although most cervical cancers contain high risk HPV types, up to 15% of such cancers test negative for HPV, raising the possibility that a few, usually more aggressive, cervical cancers may arise from from a non-viral source.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
We studied the quantity of Langerhans cells in 36 patients with cervical human papillomavirus (HPV) infection. Significantly fewer Langerhans cells (p < 0.05) were found in patients with compared to those without DNA tetraploidy. Similarly, patients positive for HPV 16/18 DNA by in situ hybridization or antipeptide IgA antibodies to HPV 18 tended to have fewer Langerhans cells than those negative for HPV 16/18 DNA or IgA antibodies. Our results suggest that depletion of Langerhans cells is associated with productive HPV 16/18 infection in the cervical epithelium.

Abstract
The aim of this work was to identify B-cell epitopes in the minor nucleocapsid (L2) protein of human papillomavirus (HPV) type 16 and characterization of allied antibody response. Serum samples of 513 individuals (323 women with various degrees of cervical atypia, 150 men and 40 small children) were available for the study. Synthetic peptides overlapping the L2 protein of HPV 16 twice were applied in ELISA for epitope scanning and antibody determination. An HPV 16 L2 derived dodecamer SGYIPANTTIPF (amino acids 391-402) proved to be the major B-cell epitope. Both IgA antipeptide antibody positivity (range 7-28%) and mean IgA antibody levels (range 13.2 EIU to 42.4 EIU, P < 0.05) increased with the degree of cervical atypia, whereas antipeptide IgG antibodies showed an opposite trend. During a 2-years follow-up significantly (P < 0.0005) decreasing IgA antibody levels to the SGYIPANTTIPF peptide were associated with regression of koilocytotic atypia. Analysis of anti-peptide IgA antibodies of 118 women with known HPV type revealed that a majority of positives had HPV 16/18 DNA. It was concluded that antibody response to the newly discovered peptide was partially type- and disease-specific. Our results also suggest an impairment of the IgG but not IgA class antibody response to HPV 16 in patients with persistent cervical HPV infection.

Abstract
BACKGROUND Infection with human papillomavirus (HPV) is considered to be the principal causal agent in the development of squamous cell carcinoma of the uterine cervix. Although adenocarcinoma of the cervix originates adjacent to the squamous epithelial neoplastic lesions, the etiopathogenesis of adenocarcinoma is not yet clearly understood. Recent studies have raised more controversy, rather than answering the question of whether specific HPV infection also plays a role in the development of adenocarcinoma of the cervix. Molecular DNA hybridization techniques were used to detect HPV types prevalent in both adenocarcinoma and squamous cell carcinoma of the uterine cervix, which is the most common cancer in Indian women. METHODS Histologically confirmed, formaldehyde-fixed, paraffin-embedded tissue sections from 12 cases of adenocarcinoma and 30 cases of squamous cell carcinoma of the uterine cervix were analyzed retrospectively for the presence of HPV DNA types 6b, 11, 16, and 18 by both Southern blot hybridization and in situ hybridization. RESULTS Of 12 adenocarcinomas, 5 (41.67%) tumors were positive for HPV DNA: All five cases were positive for HPV 16, and two (16.6%) of these were hybridized again to the HPV 18-specific DNA probe. All tumors were negative for HPV 6b and 11. In addition, no biopsy specimens were positive after hybridization with a mixed probe of HPV 31, 33, 35, 39, and 45. These results were compared to those obtained for 30 squamous cell carcinomas of the cervix. Although 20 (66%) were exclusively positive for HPV 16 and 6 (20%), more tumors were of HPV 16 related types as detected under nonstringent conditions of hybridization, only one (3%) was positive for HPV 18. The results of in situ hybridization were found to be in good agreement with those of Southern blotting. CONCLUSIONS HPV 16 is the type present almost exclusively in squamous cell carcinoma of Indian women. A higher frequency of HPV 16 in adenocarcinoma of Indian women, in contrast to HPV 18, as reported from other regions, may be attributed to geographic variation rather than to histologic differences only, and both HPV 16 and 18 may be present in adenocarcinoma of the uterine cervix.

Abstract
Twenty-five primary cervical adenocarcinomas and five cervical infiltrates from endometrial or rectal adenocarcinomas were analyzed for human papillomavirus (HPV) DNA by polymerase chain reaction with consensus and type-specific primers. Sixty-four percent (16 of 25) of the primary carcinomas and 20% (one of five) of the secondary infiltrates were positive for HPV types 16 and/or 18 DNA. Among the primary tumors HPV DNA was found in 80% of the endocervical cell-type tumors and in 60% of the endometrioid tumors, whereas two undifferentiated scirrhous carcinomas, one clear cell carcinoma, and one serous-papillary tumor were HPV negative. Human papillomavirus-positive patients were younger than HPV-negative patients (mean ages, 49.2 v 64.2 years). Our results indicate that papillomavirus play a major role in the etiology of cervical adenocarcinomas, at least in premenopausal women. However, in contrast to other studies, HPV type 18 was not the predominant type of HPV, HPV types 16 and 18 occurring with similar frequency in our patients.

Abstract
The reported rate of human papillomavirus (HPV) positivity in cases of endocervical adenocarcinoma averages 38% (range, 0% to 100%) and, in contrast to cervical squamous cell carcinoma, HPV type 18 rather than type 16 is the predominant type. The HPV positivity rate and distribution of types (status) in 114 endocervical adenocarcinoma cases (37 in situ and 77 invasive) were determined by dot blot hybridization using biotinylated probes to HPV types 6, 11, 16, 18, 31, 33, and 35. Human papillomavirus DNA was present in 27% of in situ and in 44% of invasive adenocarcinomas, and in nearly all histologic subtypes of invasive adenocarcinoma. Human papillomavirus status was not predictive of tumor grade, volume, depth of invasion, lymph-vascular space involvement, age at presentation, or year of diagnosis. Type of HPV might influence the histologic subtype of invasive adenocarcinoma, as HPV type 16 predominated in the adenosquamous carcinomas while HPV type 18 was more frequently found in all other subtypes. Since only types 16, 18, and 33 were identified, an oncogenic role for HPV in endocervical carcinogenesis was supported.

Abstract
Cultivated CD4+ T-helper cells from two patients with cervical adenocarcinoma showed responses to a peptide EKTGILTVTYHSETQRTK derived from an E2 protein of human papillomavirus type 18 (HPV 18), but not to a corresponding HPV 16 peptide (HKSAIVTLTYDSEWQRDQ). Serum antibodies in the HPV 18 peptide were also demonstrated in these patients. The GILT motif resembles a common pattern present in many T-cell epitopes, and is located at the beginning of an 11-amino acid-long A-helix structure close to the carboxyterminal end of HPV 18 E2. We conclude that two epitopes (a T-helper cell epitope and a B-cell epitope) overlap in the HPV 18 E2.

Abstract
Serum antibodies to early proteins of human papillomavirus type 16 (HPV 16 E2 protein) and herpes simplex virus type 2 (HSV 2 ICP8) can be measured by ELISA. In the serum of 122 newly diagnosed cervical carcinoma patients and age-matched controls, enhanced IgA antibody levels to an HPV-16 E2 protein derived peptide no. 245 indicated a 9.5-fold (95% confidence limits 2.8-57.2) relative risk of cervical carcinoma. No significant risk was found with a corresponding HPV 6 E2 peptide or HSV 2 ICP8. To evaluate the HPV 16 E2 peptide as a possible tumor marker for cervical carcinoma serial postoperative serum samples were tested from 27 women with cervical carcinoma. Antibody responses to the HPV 16 E2 peptide depended on the clinical stage. Stage I and II patients showed decreasing posttreatment IgA and/or IgG antipeptide antibody levels. Stage III and IV patients initially showed decreasing antipeptide antibody levels followed by increasing levels. These patients also showed increasing IgG antibody levels to the HSV 2 ICP8. However, increasing antibody levels to the HPV 16 E2 peptide indicated significantly (P less than 0.05) worse 2-year disease free survival (recurring disease) than did stable or decreasing antibody levels. The results suggest that serum antipeptide antibodies to the HPV 16 E2 peptide no. 245 can be used for the monitoring of cervical carcinoma.

Abstract
AIMS To determine if there are type specific differences in serum antibody responses to synthetic peptides derived from human papillomavirus (HPV) open reading frame (ORF) E2 in patients with cervical carcinoma. METHODS Diagnostic phase sera from 88 age-matched women with cervical adenocarcinoma (AC), cervical squamous cell carcinoma (SC), ovarian cancer (OC) or no gynaecological malignancy were available. Serum IgG and IgA antibodies to synthetic peptides corresponding to a residue of HPV 6, 11, 16, and 18 ORF E2 18 amino acids long and a control peptide from mumps virus were determined by ELISA. RESULTS Both IgA and IgG antibody positivity to the HPV 18 peptide were associated with increased risk (9.0-fold, confidence limits 1.5-199) for AC. IgA positivity to HPV 11, 16, and 18 peptides was associated with an increased risk for SC. However, the association of IgG antibodies to HPV 16 peptide with SC was not significant. IgA or IgG antibodies to HPV 6 or mumps virus peptides were not associated with increased risk for AC, SC, or OC. CONCLUSIONS These results suggest a specific role for HPV 18 in AC. Differences in antibody responses to HPV peptide in AC and SC suggest immunopathogenetic differences between the two types of cervical carcinoma.

Abstract
AIMS To determine which type of human papillomavirus (HPV) is associated with cervical adenocarcinoma and whether the virus was integrated or episomal in two continents. METHODS Biopsy specimens from the UK (n = 16) and South Africa (n = 22) were analysed by non-isotopic in situ hybridisation (NISH) for HPV types 6, 11, 16, 18, 31, 33, and 35 on archival biopsy specimens using digoxigenin labelled probes. RESULTS A total of 20 adenocarcinomas (53%) from both groups contained HPV DNA. In the UK group, seven and four cases contained HPV 18 (44%) and 16 (25%) respectively. In the South African group, nine cases contained HPV 18 (41%) while HPV DNA was not detectable in the other 13 cases. Hence HPV 18 was present in 80% of HPV positive adenocarcinomas. CONCLUSIONS The HPV 16 or 18 genome was integrated in all viral positive cases. In two cases HPV 18 was also present in an episomal form. These data indicate that HPV integration is common to cervical adenocarcinoma in two continents by the same methodology. The lower prevalence of HPV 18 detection in the South African group may have been due to the presence of other or unsequenced HPV types.

Abstract
A recent study has shown that human papillomavirus (HPV) types 16 and 18 can immortalize normal breast epithelium, and raised the possibility that HPV may be etiologically related to some cases of breast cancer. In order to investigate this possibility, we performed polymerase chain reaction (PCR) assays for HPV types 6, 11, 16 and 18 in 15 papillomas, 15 papillary carcinomas, and 13 infiltrating ductal carcinomas of the breast. No HPV-related DNA sequences were identified by Southern blotting of the PCR products. It therefore seems unlikely that a significant percentage of human breast carcinomas is etiologically related to infection with one of these HPV types.
