HPV genotyping by L1 amplicon sequencing of archived invasive cervical cancer samples: a pilot study. Infect Agent Cancer 2022; 17:44.

Abstract
BACKGROUND Human papillomavirus (HPV) is the primary cause of invasive cervical cancer (ICC). The prevalence of various HPV genotypes, ranging from oncogenically low- to high-risk, may be influenced by geographic and demographic factors, which could have critical implications for the screening and prevention of HPV infection and ICC incidence. However, many technical factors may influence the identification of high-risk genotypes associated with ICC in different populations. METHODS We used high-throughput sequencing of a single amplicon within the HPV L1 gene to assess the influence of patient age, race/ethnicity, histological subtype, sample type, collection date, experimental factors, and computational parameters on the prevalence of HPV genotypes detected in archived DNA (n = 34), frozen tissue (n = 44), and formalin-fixed paraffin-embedded (FFPE) tissue (n = 57) samples collected in the Los Angeles metropolitan area. RESULTS We found that the percentage of off-target human reads and the concentration of DNA amplified from each sample varied by HPV genotype and by archive type. After accounting for the percentage of human reads and excluding samples with especially low levels of amplified DNA, the HPV prevalence was 95% across all ICC samples: HPV16 was the most common genotype (in 56% of all ICC samples), followed by HPV18 (in 21%). Depending upon the genotyping parameters, the prevalence of HPV58 varied up to twofold in our cohort. In archived DNA and frozen tissue samples, we detected previously established differences in HPV16 and HPV18 frequencies based on histological subtype, but we could not reproduce those findings using our FFPE samples. CONCLUSIONS In this pilot study, we demonstrate that sample collection, preparation, and analysis methods can influence the detection of certain HPV genotypes and must be carefully considered when drawing any biological conclusions based on HPV genotyping data from ICC samples.

Abstract
This study investigated possible variations in the chromatin structure of koilocytes resulting from human papillomavirus (HPV) infection. Alkaline-labile sites (ALS) were detected with the DNA breakage detection–fluorescence in situ hybridization (DBD-FISH) technique using a whole human genome DNA probe obtained from individuals without koilocytosis. The variable levels of ALS present were measured quantitatively using image analysis after whole-genome DNA hybridization. A significant increase in the number of ALS was observed in koilocytes compared with normal cells. We demonstrated that the presence of ALS could be an indicator of chromatin change in koilocytes caused by HPV infection.

Abstract
Cervical cancer is a common malignancy in women worldwide, and it has now been established that the human papillomavirus (HPV) is both necessary and causal for these lesions. HPV itself is both ubiquitous and markedly heterogeneous but can nevertheless be classified as either a high-risk type or a low-risk type based upon its frequency of detection in cervical cancer. Given that the association between HPV and cervical cancer is causal, the classification of this virus has been strengthened by large-scale epidemiologic studies and is widely accepted across many disciplines. It is evident, however, that cervical cancer is frequently associated with multiple HPV types. Therefore, it is crucial to distinguish causal types of HPV (drivers) from noncausal types (passengers) in cervical lesions. In this review, we highlight the current pitfalls of using polymerase chain reaction methods instead of Southern blot hybridization for detecting HPV and discuss the distinction between driver and passenger HPVs with regard to the viral type, the length of the viral genome, and the levels of viral DNA associated with cervical cancer. Finally, we newly propose three categories of HPV instead of two risk groups, based on similarities between viral genes.

Abstract
We report on four cases of endocervical adenocarcinoma associated with lobular endocervical glandular hyperplasia using histochemical and immunohistochemical analyses. The patients ranged in age from 59 to 67 years (mean 62 years). Chief complaints were watery vaginal discharge in two cases, genital bleeding in one and no subjective symptoms in one. Cytological examinations of the cervical smears revealed adenocarcinoma cells and benign-looking glandular cells with intracytoplasmic golden-yellow mucin in all cases. Radical hysterectomy was performed in three patients, and simple total hysterectomy was performed in one. From surgical specimens, three tumors were diagnosed as mucinous adenocarcinoma and one was adenocarcinoma in situ. All adenocarcinomas were located proximally on the cervix, and did not involve the transformation zone. Adjacent to carcinoma tissues in the cervix, lobular endocervical glandular hyperplasia was detected. The cells of lobular endocervical glandular hyperplasia were dominantly positive with neutral mucin, and immunohistochemistry revealed that these cells had prominent pyloric gland mucin (HIK1083). Focal immunopositivity for pyloric mucin was also observed in three adenocarcinomas. Either CEA or p53 were immunopositive in all adenocarcinomas and negative in the tissues of lobular endocervical glandular hyperplasia. Histopathological features of the present cases suggest that some endocervical adenocarcinomas may originate from lobular endocervical glandular hyperplasia.

Abstract
The human papillomavirus (HPV) is basically always detected in squamous cell carcinoma of the cervix and its precursors; a high incidence of HPV also has been reported in adenocarcinoma and adenocarcinoma in situ of the uterine cervix. Lobular endocervical glandular hyperplasia (LEGH) was first described by Nucci in 1999. It is difficult to differentiate minimal deviation adenocarcinoma (MDA) from LEGH preoperatively or postoperatively by clinical and pathologic features. The relationships between HPV and MDA or LEGH have not been studied well because of the rare incidence of the two diseases. To our knowledge, the HPV status in LEGH has not been reported. This study was designed to investigate HPV infection in MDA and LEGH, using the polymerase chain reaction (PCR) technique. Tumor tissue lesions were microdissected and the detection of HPV and its typing were analyzed by PCR-based assay. As the control, HPV DNA was detected in all cases of squamous cell carcinoma and three of five cases of adenocarcinoma. However, no HPV DNA was detected in any of the 10 cases of LEGH or in the 3 cases of MDA. These results suggest that MDA and LEGH are probably not related to HPV infection.

Abstract
Immunotherapy of HPV-associated disease such as cervical cancer is moving from preclinical investigation to clinical trials. The viral oncoproteins E6 and E7 are ideal target antigens because their expression is mandatory in HPV-transformed tumor cells. T cells are the most important effector cells for therapeutic vaccination strategies. Therefore, the identification and characterization of HPV E6 and E7 T cell epitopes is necessary. Methods to date rely on screening for immunogenicity of peptides predicted by algorithms. Presentation of the identified peptides on tumor cells, however, needs to be confirmed. In our study, we have improved the method to identify peptide epitopes of HPV18 E7 that are actually presented by tumor cells. We induced allogeneic T-cell lines by stimulation with HPV18-positive, CD80 and HLA-A*0201 transfected cervical cancer cells. Sensitized T cells were probed against an array of a HPV18 E7 20mer peptide-library. We found specific reactivity to one of the 20mer peptides. This sequence was then screened via algorithms for putative epitopes. One putative HLA-A2 restricted epitope was confirmed to bind to HLA-A2, to be immunogenic and to induce IFN gamma-release in ELISpot assays. Epitope-specific T cells were cytolytic toward autologous peptide pulsed targets and HPV18 transformed tumor cells. The identification of epitope-specific T cells in tumor infiltrating lymphocytes of a HPV18-positive HLA-matched cervical cancer patient suggests an in vivo relevance of the identified epitope. We suggest that our approach is advantageous over conventional methods, because it yields candidate peptides that are relevant CTL epitopes that are expressed, processed and presented by tumor cells.

Abstract
Cervical cancer represents the second most common malignant neoplasia in women world-wide. In Mexico, cervical cancer is the most common female malignancy. It has been recently seen an increased frequencies of micronuclei (MN) lymphocytes and cervical epithelial cells of cervical cancer patients. The aim of this hospital-based unmatched case-control study was to investigate the association between progressive stages in development of cervical cancer and frequency of micronucleated cells in the cervical epithelium and peripheral lymphocytes of 40 women, grouped by disease stage. Women at the Obstetrics and Gynecology Hospital of the Instituto Mexicano del Seguro Social (IMSS) in Monterrey, Mexico were diagnosed and classified on the bases of the Papanicolaou (PAP) smear and colposcopy/biopsy into control, low-grade squamous intraepithelial lesions (LGSIL), high-grade squamous intraepithelial lesions (HGSIL), and invasive groups. Analysis of the MN data in both cell types revealed (a) homogeneity among women within each of the four groups with regard to MN frequency, (b) in general, a correlation between MN frequency and grade of cervical lesion, and (c) a positive linear trend between the MN frequency and increased cervical cancer risk. In conclusion, we suggest that MN are a useful biomarker of cancer risk. Nonetheless, these results should be validated by other researchers.

Abstract
Carcinosarcomas (malignant Müllerian mixed tumors [MMMTs]) of the uterine cervix are rare neoplasms. This report describes the morphology, immunohistochemical profiles, and human papillomavirus (HPV) status of eight cervical MMMTs. Patients' ages ranged from 32 to 93 years (mean, 61 years). Seven cases showed in situ squamous cell carcinoma (SCC). The invasive epithelial component (EC) was composed of combined adenoid basal carcinoma, basaloid SCC, and adenoid cystic carcinoma (ACC) in two cases. Keratinizing SCC, large cell nonkeratinizing SCC, undifferentiated carcinoma, and basaloid SCC predominated in the remaining tumors, one of which had admixed ACC. The sarcomatous component (SC) was homologous and spindled with admixed myxoid areas in three lesions. The ECs and SCs in six MMMTs showed dual immunostaining with epithelial membrane antigen and the pan-keratin marker, MNF116. The SC was vimentin-positive in seven cases. Five tumors had a vimentin-positive EC. The SC was positive for muscle specific actin and/or smooth muscle actin in seven lesions, of which four were desmin-positive. Polymerase chain reaction (PCR) using GP5+/GP6+ L1 consensus primers detected HPV DNA in all eight cases. Nonisotopic in situ hybridization with digoxigenin-labeled probes to HPV types 6, 11, 16, 18, 31 and 33 demonstrated integrated HPV 16 in three cases, not only in the EC, but also in nuclei of the SC. This is the first study to implicate HPV in the evolution of cervical MMMTs. The above observations lend support to a metaplastic theory of histogenesis.

Abstract
The differential diagnosis between primary endocervical adenocarcinoma and adenocarcinoma originating in the endometrium may in some cases be difficult. The two cancer types have a different genesis, with human papillomavirus (HPV) as an important causal factor in the development of primary cervical carcinoma. In this study, the paraffin-embedded cervical tissues from 23 patients with stage II endometrial carcinoma and from 50 patients with primary cervical adenocarcinoma were examined for HPV DNA of types 16, 18, and 33. HPV DNA was demonstrated in 70% of the primary endocervical adenocarcinomas and in none of the endometrial carcinomas. It is concluded that HPV detection may be useful in the differential diagnosis of some cases of cervical and endometrial adenocarcinoma.

Abstract
Human papillomavirus (HPV) DNA sequences were detected by Southern blot hybridization and polymerase chain reaction (PCR) in 10 out of 19 patients (52.7%) with adenocarcinoma [15] and adenosquamous [4] carcinoma of the uterine cervix. HPV 18 DNA was detected in 8 of these 19 patients (42.1%), HPV 16 DNA in 1 patient (5.3%) and HPV type X (unknown) in another (5.3%). Of the 10 HPV positive samples HPV 18 was found in 6 out of 6 pure adenocarcinomas (100%), and in 2 of 4 (50%) adenosquamous carcinomas. HPV 16 and HPV X were each detected in 1 out of 4 (25%) adenosquamous carcinomas. The physical state of the viral DNA was investigated in 5 of the 10 HPV-positive cases. All the specimens from these 5 cases showed HPV to be integrated into the host genome, except for one adenosquamous specimen, which showed both episomal and integrated forms of HPV 16. Six of 8 HPV 18 DNA positive specimens were from cases of pure adenocarcinoma and it was found by PCR that five of these 6 specimens retained fragments of E6/E7, LCR/E7 and early sequence of E1 fragment (sequence: 1188-1373) but deleted most part of E1.

Abstract
AIM To investigate the role of human papillomavirus (HPV) in adenoid cystic carcinoma of the uterine cervix. METHODS Eleven archival, paraffin wax embedded specimens were analysed by non-isotopic in situ hybridisation (NISH) for HPV types 6, 11, 16, 18, 31, and 33 using digoxigenin labelled probes. The polymerase chain reaction (PCR) was carried out on each of the cases using consensus primers to HPV. RESULTS A total of eight adenoid cystic carcinomas harboured the HPV genome by NISH, of which five were PCR positive. Integrated HPV 16 DNA was demonstrated in seven of the eight NISH positive cases. One adenoid cystic carcinoma showed integrated HPV 31. HPV DNA was not detected in the three remaining cases. CONCLUSIONS Integrated high risk HPV genome, in particular type 16, is associated with this uncommon type of primary cervical cancer.

Abstract
New patterns of cellular presentation on cervical smears have become more frequent since the introduction of new sampling devices which provide increased material from the upper portions of the endocervical canal. The normal histologic variability of the endocervical canal, as well as the presence of tubal metaplasia, infectious and inflammatory reactions, squamous lesions involving endocervical glands, and true endocervical neoplastic lesions in these areas, have presented the cytologist with a variety of cellular appearances which may cause difficulties in differential diagnosis. Recognition of these entities, their cytologic manifestations, and the effects of increased high endocervical sampling, will allow the cytologist to begin the process of gaining the experience necessary to assess these new cellular patterns. A potential management protocol for patient follow-up is presented which will allow the user to investigate such cases in an efficient and cost effective manner.

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
An integrated study on the role of human papillomaviruses (HPV) in cervical cancer has been conducted. Out of a total of 433 cases of cervical cancer, HPV-DNA was detected in 342 (79%) using the polymerase chain reaction (PCR). The incidence of HPV infection was not significantly related to histological types, although a lower incidence was noted in adenocarcinoma cases. The incidence of lymph node (LN) metastasis in adenosquamous carcinoma (55.6%) was significantly higher than in squamous cell carcinoma (SCC) and adenocarcinoma. HPV 16 was detected significantly more often in SCC than in adenocarcinoma. In contrast, HPV 18 was detected more often in adenocarcinoma than in SCC. As a whole, pelvic LN metastases were found in 24.3% of HPV+ cases, significantly higher than 11% of HPV- cases. However, the significant association of HPV-DNA with LN metastasis was only noted in stage I but not stage II. As far as histological types were concerned, the incidence of positive LN was: HPV+ SCC > HPV- SCC (p < 0.01), whereas HPV- adenocarcinoma > HPV+ adenocarcinoma (p = 0.12). Genotypes of HPV did not have any effect on nodal status. The presence of types of HPV were not associated with tumor size and distribution of clinical stage. Our results suggest that the prognostic significance of HPV-DNA on nodal status is dependent on histological types while the genotypes of HPV cannot account for prognostic significance in cervical cancer.

Abstract
BACKGROUND Among malignancies of the uterine cervix, the percentage of adenocarcinomas seems to have increased in recent reports. METHODS The clinical presentation of adenocarcinoma of the uterine cervix during the past 25 years was examined by review of charts and pathologic specimens. The data of a total of 124 patients with cervical adenocarcinoma treated between 1964 and 1988 were evaluated. RESULTS During the 25-year period, the percentage of adenocarcinoma among all cervical malignancies increased from 9% to 25%. In addition, the average number of new cases per year increased from 3.7 to 10.8. The percentage of women young than 35 years with adenocarcinoma increased from 16% in 1964 to 24% in 1989. Of these younger women, 74% had disease discovered by cytopathology, in comparison with 27% of the patients who were older than 35 years. The overall percentage of patients with disease diagnosed by cytology increased from 24% in the first half to 39% in the second half of the study period. Vaginal bleeding was the most common symptom. In the entire period, 57% of patients had International Federation of Gynecology and Obstetrics (FIGO) Stage I disease, with a median tumor diameter of 1 cm in patients with no symptoms and 3 cm in patients with symptoms. Outcome was inversely related to stage, tumor volume, and the presence of lymph node metastasis but not to histologic tumor type. CONCLUSION The frequency of adenocarcinoma of uterine cervix is increasing in patients 35 years or younger. Cytopathology is a good screening tool for these patients, leading to earlier diagnosis and improved outcome.

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
Thirty-two cervical adenocarcinomas and adenosquamous carcinomas were examined to search for human papillomaviruses (HPVs) using the polymerase chain reaction system. Human papillomavirus type 16 (HPV16) and type 18 (HPV18) deoxyribonucleic acid was detected in 22% and 16% of these carcinomas, respectively. HPV16 was the most common type in both adenocarcinoma and adenosquamous carcinoma, and the mean age of the HPV negative patients was significantly higher than that of HPV positive patients. There may be an association between HPVs and the development of certain adenocarcinomas and adenosquamous carcinomas of the 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
Although human papilloma virus (HPV) associated lesions constitute a well recognized clinical entity in the female lower genital tract, namely vulva, vagina and cervix, few studies have demonstrated HPV infection in other genital sites, particularly in the ovary and uterine corpus. Recently, with the highly sensitive polymerase chain reaction (PCR) technique, HPV infections were found in an ovarian tumour and adenocarcinoma of the cervix. This prompted a retrospective analysis of HPV DNA in 22 cases of endometrial adenocarcinoma in order to investigate the possible carcinogenesis of HPV in the uterine corpus. In this study DNA extraction was performed from paraffinized cancerous tissues and the normal cervical counterpart. HPV 6, 11, 16 and 18 primers specific oligonucleotides were used in PCR to detect the presence of this oncogenic virus. HPV 16 DNA was found in 1 endometrial adenocarcinoma and 4 cervical tissues. Our result did not support the aetiological role of HPV in the carcinogenesis of endometrial carcinoma.

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
In order to detect human papillomavirus (HPV) DNA in invasive cervical cancers, three different polymerase chain reactions to amplify different subgenomic fragments of HPV DNA were carried out on DNA extracted from 93 formalin-fixed and paraffin-embedded tumor tissues. This study detected HPV DNA in 54 cases (58.1%), which broke down to HPV 16 in 39 (41.9%) cases, HPV 18 in six (6.4%), HPV 52 in three, HPV 33 in one and unclassified HPV type in the remainder. Histopathologically, squamous cell carcinomas frequently contained HPV 16, whereas, HPV 18 was present in adenocarcinoma, adenosquamous cell carcinoma and small cell carcinoma of the cervix. Clinicopathological study revealed that HPV 16 and 18 DNA found were more frequently than other HPV subtypes in premenopausal patients. Moreover, HPV 18 DNA-positive cancers had a relatively high recurrence rate. These results indicate that cervical cancers might be clinically influenced by the difference in subtypes of the infecting HPV.

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
We studied 30 women with cervical lesions that showed human papillomavirus infection (HPV). Cervical HPV infection was diagnosed by cytology, histology, immunohistochemistry, and electron microscopy, as well as by DNA viral hybridization in situ with 6, 11, 16, and 18 HPV types. Three groups of patients were studied: 15 women infected by HPV of 6 and 11 types with koilocytic lesions and benign evolution, 15 women infected by HPV of 16 and 18 types with koilocytic lesions and malignant evolution, and 15 normal women without cervical lesions who served as controls. For each group, chromosome fragility was studied in peripheral blood lymphocytes. Aphidicolin (AP) was used as a clastogenic agent at a concentration of 0.12 microM. There were significant differences (p less than 0.001) between the control population and the patients affected by HPV. There were also significant differences (p less than 0.001) between the two groups infected with HPV. Our findings support the concept that chromosome fragility could serve as a cytogenetic marker to measure evolution, prognosis, and treatment of cervical lesion associated with HPV.

Abstract
The argyrophil technique for nucleolar organizer regions was applied to cases of normal cervix (n = 6), microglandular hyperplasia (n = 6), adenocarcinoma in situ (n = 15), and invasive adenocarcinoma of the cervix (n = 19). A rigorous staining technique was employed which facilitated the enumeration of individual AgNORs even when they were aggregated as tight clusters within the nucleolus (AgNUs). Two methods of counting AgNORs were used: a simple enumeration of dispersed AgNORs and AgNUs, and the more time-consuming counting of all individual AgNORs, including those within AgNUs. With both techniques, there was no significant difference in counts between in situ and invasive adenocarcinoma, but cases of microglandular hyperplasia showed significantly fewer AgNORs than either of these. This suggests that AgNORs may be useful in differentiating difficult cases of microglandular hyperplasia from adenocarcinoma and that the simplified counting technique is adequate for this purpose. AgNOR counts are of no use in discriminating between invasive and in situ adenocarcinoma.

Abstract
Tumor tissues from 29 women with borderline or malignant epithelial ovarian tumors were examined for the presence of human papillomavirus (HPV) DNA by the polymerase chain reaction (PCR). The PCR analysis used a set of consensus primers that are complementary to highly conserved sequences in the genital HPVs (M. M. Manos, Y. Ting, D. K. Wright, A. J. Lewis, T. R. Broker, and S. M. Wolinsky, Cancer Cells 7, 209-214, 1989). Amplification products were detected by Southern hybridization with consensus oligonucleotide probes. A total of 70 paraffin-embedded tissue sections from ovarian carcinomas were tested and we did not detect genital-type HPV DNA sequences in any of these specimens. However, all of the tissue specimens were considered adequate for PCR analysis because a human cellular gene (beta-globin) was successfully amplified in each tissue specimen. In addition, HPV 16 DNA was found in a concurrent invasive squamous-cell carcinoma of the cervix from one ovarian cancer patient, indicating that the PCR was able to detect HPV in the lower genital tract of this individual. We conclude that there is no association between infection with the most common genital HPVs and borderline and malignant epithelial ovarian tumors.

Abstract
The aim of this study was to investigate papillomavirus (HPV)-DNA in precancer and cancer of the cervix, vulva, and endometrium by in situ/dot blot/Southern blot hybridization and polymerase chain reaction (PCR). Myc/erbB-2 expression was examined by Northern blot analysis. PCR was the most sensitive HPV detection method, demonstrating HPV-DNA in all pre-invasive and invasive cervical lesions (n = 21) and most (3 of 4) vulvar carcinomas in contrast to an overall rate of 60% with other techniques. Particular phenotypes (adenoid cystic/basal cell carcinoma of the vulva, cervical adenocarcinoma) were found to contain HPV. Endometrium harboured HPV not only in two cases of cervical cancer, but also in 3 of 8 primary endometrial carcinomas and 3 of 8 non-malignant conditions. Myc activation was confined to three squamous cell carcinomas, most markedly in one HPV-6-positive verrucous variant. ErbB-2 over-expression was only seen in one HPV-18 infected advanced endometrial tumour. Our findings point to a range of HPV-infected lesions broader than previously supposed and possible contributions of HPV-independent molecular events to carcinogenesis in this field.

Abstract
During the past decade a wide span of heterogeneity has been demonstrated for human papillomaviruses (HPVs), and some basic properties of the HPV genome have been revealed. The use of hybridization assays for HPV DNA detection in infected epithelia, and the recent introduction of synthetic HPV peptides for detection of type-specific circulating antibodies, have resulted in a major rethinking of HPV epidemiology. Recent data indicate that various HPVs may be transmitted perinatally during early infancy and that a long latency with periodic reactivation seems to be quite common. The present review attempts to assess recent epidemiological data with the concept of genitoanal papillomavirus infection (GPVI) as a predominantly sexually transmitted disease. Some diagnostic and therapeutic aspects are outlined with a pragmatic approach to the clinical relevance of GPVI.

Abstract
Vaginal adenosis and clear cell adenocarcinoma of the vagina occurred in a 44-year-old woman after treatment for condylomata acuminata. She had no known exposure to diethylstilbestrol (DES) in utero. Biopsy-proven vaginal adenosis appeared 8 months after intravaginal 5-fluorouracil application for recurrent urogenital condylomata acuminata. Forty months later, biopsies showed residual adenosis with foci of clear cell adenocarcinoma. Although clear cell adenocarcinoma is associated with vaginal adenosis and cervical ectropion in DES-exposed women, its occurrence in adenosis after 5-fluorouracil therapy has not been reported to the authors' knowledge. In this report, this rare but serious complication of treatment of condylomata acuminata is highlighted, and the literature regarding the development of non-DES-associated vaginal adenosis is discussed.

Abstract
In-situ hybridization using biotinylated probes to human papillomavirus (HPV) DNA was performed on formalin fixed paraffin embedded tissue in 30 patients with histologically confirmed adenocarcinoma-in-situ (AIS). Thirteen of the 30 cases contained areas of endocervical glandular dysplasia (EGD) admixed with AIS. Twenty one patients showed positive staining of the AIS nuclei for HPV DNA. Ten cases (33%) were positive for HPV 16 DNA and 11 cases (37%) were positive for HPV 18 DNA. No case showed synchronous expression of HPV 16 and 18 DNA. All cases of AIS were negative for HPV 6b and 11 DNA. Four cases of EGD were positive for HPV 18 DNA and 2 cases were positive for HPV 16 DNA. Four of 6 cases of intestinal dysplasia/AIS were positive for HPV 18 DNA. Associated squamous abnormalities (HPV +/- CIN +/- SCC) were noted in 15 cases. Of these, 7 showed positive staining for HPV DNA in the squamous lesion. Moreover, 5 of these were positive in both the AIS and squamous lesion. In-situ hybridization using biotinylated DNA probes is a sensitive and safe technique readily adaptable to routine histopathology.

Abstract
A few studies using DNA technology have suggested that human papillomavirus (HPV) may be an aetiological factor for adenocarcinoma of the uterine cervix. Twenty one cases of cervical adenocarcinoma were studied by in situ hybridisation using biotinylated DNA probes for HPV types 6, 11, 16 and 18 and a streptavidin, biotinylated alkaline phosphatase detection system. Intranuclear HPV DNA was detected in none of the adenocarcinomas, while positive controls gave a clear intranuclear signal. Adjacent areas of normal, koilocytic, and dysplastic squamous epithelium also gave positive results. It may be that squamous epithelium contaminates adenocarcinomas reported as positive by Southern blotting. Our results showing absence of detectable HPV DNA within adenocarcinomas suggest that HPV infection may not have a major role in the aetiology of adenocarcinoma of the uterine cervix.

Abstract
The past two decades have seen an increase in the incidence of endocervical carcinoma. Numerous studies have increased understanding of these tumors; hormonal therapy, human papilloma virus, and other cofactors have been implicated in the etiology of endocervical carcinoma. Early diagnosis is difficult: precursor lesions to adenocarcinoma in situ are still poorly defined and understood, and there may be a rapid transit time from in situ to invasive carcinoma. The definition of microinvasive adenocarcinoma is not uniformly agreed upon, and at this time the recommendation is not to use the term. Histologic typing and grading of adenocarcinoma may be useful in the prediction of prognosis for patients. Therapy is based upon stage of disease, the most beneficial results being obtained from either radical surgery or combination surgery and radiation therapy.

Abstract
Fifty-four pairs of cervical biopsies ranging from minimal dysplasia to severe dysplasia were studied for the presence of human papillomavirus DNA by in situ hybridization. Two assays were performed on each biopsy. A 16 hour hybridization was used in one assay, while a 40 hour hybridization was utilized in the second assay. Increasing the hybridization time to 40 hours did not significantly increase the detection rate of HPV compared to the rate found using the 16 hour hybridization. Also, no difference in the detection rate of HPV was found by using one biopsy of the pair over the other biopsy of the pair. However, the performance of a single in situ assay on only one biopsy from each patient significantly underestimated the true prevalence of HPV. A single assay only detected 21/33 (64%) patients with HPV. Implications of multiple testing of all histologically abnormal biopsies is discussed in relation to prospective follow-up studies determining the usefulness of HPV typing in patient management.

Abstract
There is general evidence that the incidence of adenocarcinoma of the cervix has been rising, particularly among younger women. The determinants of these trends, however, remain largely unknown. We have reviewed the epidemiology of adenocarcinoma of the cervix using descriptive data from cancer registration and clinical series and two main sources of analytical data: clinical studies comparing cervical adenocarcinoma (AC) and squamous carcinoma (SC) and formal case-control and cohort epidemiological studies. In both the United States and northern Europe there is evidence of the rising frequency of AC in absolute and relative terms as compared to SC. These trends are generally restricted to younger women: under-age-35 AC incidence approximately doubled from the early 1970s to the early 1980s. Available data, although scanty, consistently show that the frequency of cervical adenocarcinoma rises with the number of partners and with decreasing age at first intercourse, suggesting a potential role for sexually transmitted (viral) factors. In clinical series, nulliparity was reported more frequently in AC than in SC cases but an inconsistent association was found in three formal epidemiological studies. Similarities with the epidemiology of endometrial cancer are also suggested from the association with overweight, while a possible relation with hypertension and diabetes is based on clinical series only and hence more difficult to interpret. Thus, adenocarcinoma of the cervix appears to share epidemiological characteristics with both adenosquamous cancer of the cervix and adenocarcinoma of the endometrium, although uncertainties in classification and registration leave several questions unanswered.

Abstract
The distribution of human papillomavirus (HPV) DNA type 16/18 in the paraffin sections of 11 adenocarcinomas (AC), 4 adenocarcinomas in situ (AIS), and 2 adenosquamous carcinomas (AC/SCC) of the cervix was examined by in situ hybridization (ISH) with biotinylated DNA probes (B-probes). Four AC, four AIS, and one AC/SCC were positive. These results show that B-probes are an acceptable alternative to both ISH with radiolabeled probes and Southern blot hybridization (SBH), which are difficult to apply in routine pathologic laboratories. Cervical tissues infiltrated with endometrial AC were negative for HPV DNA 16/18, and it is suggested that the presence of HPV DNA 16/18 in uterine AC may be helpful in discriminating cervical AC from endometrial AC.

Abstract
During the last decade a large number of clinical, epidemiological, and experimental studies have elucidated the role of HPV in the pathogenesis of anogenital cancer. Although the clinical and epidemiological studies have been criticized for a variety of technical and design shortcomings, for the most part they have independently reached the same conclusion--there is a strong association between the presence of specific types of HPV and the development of anogenital cancer. Similarly, laboratory studies clearly indicate that specific types of HPV act in concert with other cellular changes to transform a variety of cell types in vitro, including human cervical epithelial cells. Over the next decade the challenge is twofold. First we need to define precisely the mechanisms by which HPV either by itself or in concert with other factors, acts to transform anogenital epithelial cells. These studies will, it is hoped, identify important cofactors in the transformation process and determine the role of host immunity. Second, we need to determine the clinical applicability of the association between HPV and anogenital cancer. Large clinical studies will determine whether HPV testing of asymptomatic patients facilitates the detection of patients at risk for developing cervical cancer and whether the presence of a specific type of HPV in a cervical cancer actually affects a patient's prognosis. As the answers to these and other questions become available, we will be in a better position to assess the clinical importance of the associations between HPV and anogenital cancer.

Abstract
The incidence of adenocarcinoma of the cervix appears to be increasing. Recent reports have demonstrated an association between adenocarcinoma of the cervix and human papillomavirus (HPV) by Southern blot hybridizations. In situ deoxyribonucleic acid (DNA) hybridization was performed on paraffin-embedded specimens to localize the source of HPV DNA. In pure adenocarcinoma five of six specimens were positive for HPV DNA. Four specimens contained HPV type 18 and one HPV type 16. Only one of three adenosquamous lesions was positive and it contained both HPV types 16 and 31. These findings suggest an association between HPV and adenocarcinoma of the cervix.
