Abstract
Background Uterine Cervical Carcinoma (UCC) is the most prevalent gynecological malignancy globally, with a rising incidence in recent years. Accumulating evidence indicates that specific viral infections, including human papillomavirus (HPV), Epstein-Barr virus (EBV), Hepatitis B and C viruses (HBV and HCV), and human herpesvirus (HHV), may contribute to UCC development and progression. Understanding the complex interplay between viral infections and UCC risk is crucial for developing novel preventative and therapeutic interventions. Methods This comprehensive review investigates the association between viral infections and UCC risk by examining the roles of various viral pathogens in UCC etiology and pathogenesis, and possible molecular mechanisms. Additionally, we evaluate current diagnostic methods and potential therapeutic strategies targeting viral infections for UCC prevention or treatment. Results The prevention of UCC has been significantly advanced by the emergence of self-sampling for HPV testing as a crucial tool, allowing for early detection and intervention. However, an essential challenge in UCC prevention lies in understanding how HPV and other viral coinfections, including EBV, HBV, HCV, HHV, HIV, or their concurrent presence, may potentially contribute to UCC development. The molecular mechanisms implicated in the association between viral infections and cervical cancer development include: (1) interference of viral oncogenes with cellular regulatory proteins, resulting in uncontrolled cell proliferation and malignant transformation; (2) inactivation of tumor suppressor genes by viral proteins; (3) evasion of host immune responses by viruses; (4) induction of a persistent inflammatory response, contributing to a tumor-promoting microenvironment; (5) epigenetic modifications that lead to aberrant gene expression; (6) stimulation of angiogenesis by viruses; and (7) activation of telomerase by viral proteins, leading to cellular immortalization. Additionally, viral coinfections can also enhance oncogenic potential through synergistic interactions between viral oncoproteins, employ immune evasion strategies, contribute to chronic inflammation, modulate host cellular signaling pathways, and induce epigenetic alterations, ultimately leading to cervical carcinogenesis. Conclusion Recognizing the implications of viral oncogenes in UCC etiology and pathogenesis is vital for addressing the escalating burden of UCC. Developing innovative preventative and therapeutic interventions requires a thorough understanding of the intricate relationship between viral infections and UCC risk.

Abstract
OBJECTIVE HPV is a common sexually transmitted infection and is considered to be a necessary cause of cervical cancer. The anatomical proximity to the cervix has led researchers to investigate whether Human Papillomavirus (HPV) has a role in the etiology of endometrial cancer. METHODS We conducted a systematic review and meta-analysis to investigate the pooled prevalence of HPV DNA in endometrial cancer. Using meta-regression, we further analyzed whether factors such as geographical region, HPV DNA detection method, publication year and tissue type were associated with HPV prevalence. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for studies providing data on HPV prevalence in cases with endometrial cancer and in controls with normal or hyperplastic endometrial tissue. RESULTS We identified 28 papers (29 studies) examining the prevalence of HPV DNA in tumor tissue from endometrial cancer comprising altogether 1026 cases of endometrial cancer. The HPV prevalence varied considerably from 0% to 61.1%. From the random effects meta-analysis, the pooled prevalence of HPV DNA in endometrial cancer was 10.0% (95% CI: 5.2-16.2) with large between-study heterogeneity (I(2)=88.2%, p<0.0001). The meta-regression showed that HPV DNA detection method was statistically significantly associated with HPV prevalence (p=0.0016): the pooled HPV prevalence was 6.0% (95% CI: 1.5-13.0) using general primers, 18.9% (95% CI: 8.6-32.1) using type-specific primers and 1.0% (95% CI: 0.0-3.6) using non-PCR based methods. None of the other a priori defined variables were statistically significantly associated with HPV prevalence. The pooled OR was 1.43 (95% CI: 0.68-3.00) indicating that the odds of HPV was not increased in cases versus controls. CONCLUSIONS HPV appears to have a limited or no role in the etiology of endometrial cancer.

Abstract
Aims. To investigate the possible association
of human papillomavirus (HPV) with endometrial hyperplasias and
neoplasia. Does HPV play any role in the initiation or
prognosis of endometrial adenocarcinomas?
Methods. Twenty-five endometrial adenocarcinomas
of the endometrioid cell type, with and without squamous
differentiation, and twenty-four endometrial hyperplasias of various
forms (simple, complex, and atypical) were analyzed for the
presence of type 16 and 18 HPV by the polymerase chain
reaction (PCR). The results were related to histopathological
features of the tumour, and the patients' age, and
prognosis. Results. Six of 25 endometrial
adenocarcinomas were HPV 16-positive
(24%),
and 5 of 25
(20%)
were HPV 18-positive. Simple endometrial hyperplasias was
associated somewhat more commonly with HPV 16 and 18 (2/8 and
1/8 cases, resp.) than hyperplasias progressing to
endometrial adenocarcinomas, namely, atypical endometrial
hyperplasia (1/8 and 0/8 cases, resp.). None of the
positive cases in the series, whether hyperplastic or
neoplastic, demonstrated cytological evidence of HPV
infection. There was no relation between HPV-positive cases
and squamous differentiation, depth of myometrial invasion,
lymphatic involvement, lymphocytic response, patients' age,
or prognosis. Conclusion. It appears that the
presence of HPV in the endometrium, as detected by PCR, does
not play any role in the initiation or prognosis of
endometrial adenocarcinoma.

Abstract
We report herein a small cell neuroendocrine carcinoma of the endometrium that extended to the cervix and showed strong immunohistochemical staining for p16. The p16 staining raised the possibility of a human papillomavirus (HPV)-related tumor, because in the cervix, a positive p16 immunohistochemical stain is presumptive evidence of HPV. However, the current case was HPV negative. We discuss the molecular pathogenesis of non-HPV-related increased p16 expression.

Abstract
We report two cases of endometrial microglandular adenocarcinoma, a rare neoplasm, which, in its morphologic features, mimics cervical microglandular hyperplasia and mucinous proliferations of endometrium. The criteria for a correct pathological diagnosis, such as clinical, morphologic, and immunohistochemical data, are emphasized. For the first time, we probed to establish whether endometrial mucinous microglandular adenocarcinoma could be correlated to human papilloma virus (HPV) infection by using polymerase chain reaction amplification (PCR) of tumoral DNA. Similar to previous studies reported in the literature, the present lesions, occurring in postmenopausal women, immunohistochemically showed positivity for B72.3, Ca 125, CEA, Vimentin, estrogen and progesterone receptors, and negativity for p53. Molecular study by PCR amplification of tumor DNA showed no signal for HPV DNA in any of these cases; thus, this variant of endometrial carcinoma is not caused by the HPV infection, but probably by other pathogenetic mechanisms, such as an accumulation of the mutations, which arrive in old age or as the consequence of a peculiar hormonal situation.

Abstract
BACKGROUND Distinguishing endocervical adenocarcinoma (ECA) from endometrial mucinous adenocarcinoma (EMMA) is clinically significant in view of the differences in their management and prognosis. In this study, we used a panel of tumor markers to determine their ability to distinguish between primary endocervical adenocarcinoma and primary endometrial mucinous adenocarcinoma. METHODS Immunohistochemistry using monoclonal antibodies to MUC1 (Ma695), p16, estrogen receptor (ER), progesterone receptor (PR), and vimentin, was performed to examine 32 cases, including 18 EMMAs and 14 ECAs. For MUC1, cases were scored based on the percentage of staining pattern, apical, apical and cytoplasmic (A/C), or negative. For p16, cases were scored based on the percentage of cells stained. For the rest of the antibodies, semiquantitative scoring system was carried out. RESULTS For MUC1, majority of EMMA (14 of 18 cases, 78%) showed A/C staining, whereas only few ECA (2 of 14, 14%) were positive. The difference of MUC1 expression in the two groups of malignancy was statistically significant (p < 0.001). Staining for p16 was positive in 10 of 14 (71%) ECA and 4 of 18 (22%) EMMA. Estrogen receptor was positive in 3 of 14 (21%) ECA and 17 of 18 (94%) EMMA. Progesterone receptor was positive in 3 of 14 (21%) ECA and 16 of 18 (89%) EMMA. Vimentin was positive in 1 of 14 (7%) ECA, and 9 of 18 (50%) EMA, with median and range of 0 (0-6), and 1.5 (0-9) respectively. CONCLUSION A panel of immunohistochemical markers including MUC1, p16, ER, PR, and vimentin is recommended, when there is morphological and clinical doubt as to the primary site of endocervical or endometrial origin.

Abstract
AIMS Distinguishing between adenocarcinomas of endocervical and endometrial origin histologically can be difficult, particularly in small biopsies. Most endocervical adenocarcinomas contain human papillomavirus (HPV) deoxyribonucleic acid (DNA) of 'high-risk' (HR) types, whereas this has not been consistently demonstrated in endometrial adenocarcinomas. The aim of this study was to determine whether HPV DNA testing could aid in this differential diagnosis. METHODS The frequency of HPV DNA in paraffin-embedded tissue samples from 50 endocervical and 50 endometrial adenocarcinomas was investigated using polymerase chain reaction (PCR) amplification techniques involving (i) a screening HPV test followed by HPV DNA sequencing, and (ii) a test designed to detect HR genotypes 16, 18, 31, 33, 35, 45 and 58. Control specimens included cervical intraepithelial neoplasia (CIN) III lesions, squamous cell carcinomas (SCCs) of the cervix and lung, and colonic adenocarcinomas. Measures to minimise cross-contamination were implemented. RESULTS The screening test followed by HPV DNA sequencing had the highest sensitivity. By this test HR HPV DNA was detected in 11 of 11 (100%) cervical intraepithelial neoplasia (CIN III) lesions, nine of 10 (90%) cervical SCCs, none of 10 (0%) colorectal adenocarcinomas and none of 10 (0%) SCCs of the lung. Thirty-nine (78%) endocervical adenocarcinomas contained HR HPV DNA, compared to one (2.0%) endometrial adenocarcinoma. CONCLUSIONS The results suggest that HPV DNA testing could be a useful adjunct in distinguishing between endocervical and endometrial adenocarcinomas in curettings or small biopsy specimens.

Abstract
The distinction between an endometrial and an endocervical origin of an adenocarcinoma may be difficult, especially with small biopsy specimens or when tumor is present in both endometrial and cervical specimens. Previous studies have investigated the value of antibodies such as carcinoembryonic antigen, estrogen receptor, and vimentin in making this distinction. We investigated the value of p16 immunohistochemistry for distinguishing between an endometrial and an endocervical origin of an adenocarcinoma. Cases included in the study were endometrial adenocarcinomas of endometrioid type (n=29) and cervical adenocarcinomas of endocervical type (n=23). Cases were scored on a scale from 0 to 5 depending on the percentage of positive tumor cells: 0 (negative or occasional cells positive); 1 (<5% cells positive); 2 (5-20% cells positive); 3 (21-50% cells positive); 4 (51-99% cells positive); 5 (100% cells positive). Twenty-two of 23 (96%) endocervical adenocarcinomas were scored 5; the other was scored 0. The numbers of endometrial adenocarcinomas with scores of 0 to 5, respectively, were 1, 7, 4, 9, 5, and 3. Most primary endocervical adenocarcinomas were characterized by strong, diffuse positivity of 100% of cells with p16. Endometrial adenocarcinomas are usually positive, but positivity is generally focal and commonly involves <50% of cells. However, occasional endometrial adenocarcinomas exhibit 100% positivity. Diffuse, strong positivity with p16 suggests an endocervical rather than an endometrial origin of an adenocarcinoma. When there is morphological doubt this antibody may be of value as part of a panel for ascertaining the origin of an adenocarcinoma. Diffuse, strong positivity with p16 in endocervical adenocarcinomas is likely caused by inactivation of the retinoblastoma protein by the E7 human papillomavirus oncoprotein, which acts as a p16 transcript repressor.

Abstract
Patients undergoing radiotherapy for advanced cervical and endometrial cancer bear a considerable risk of developing vaginal preneoplastic lesions. Radiotherapy itself has been considered to have a role in the pathogenesis of vaginal dysplasia, although human papillomavirus (HPV) involvement has also been suggested. A series of 88 patients who underwent hysterectomy and were irradiated for gynecological cancer, including 43 with postradiation vaginal dysplasia at colposcopy and 45 without vaginal lesions, were included in this study. Detection and genotyping of HPV DNA in vaginal scraping were carried out by a PCR-based method and compared with colposcopic and cytological findings and with other clinical and laboratory data. Forty-two (97.7%) colposcopy-positive subjects and 6 (13.3%) colposcopically-negative patients were PCR-positive for high-risk HPV DNA (P < 0.000001). Twenty-two out of the 43 patients with colposcopic lesions showed an abnormal Papanicolau (PAP) test. Cytologic examination was negative in all colposcopically negative women. Type 16 HPV DNA was more frequent in patients with high-grade squamous intraepithelial lesions and in patients treated with external radiotherapy, whereas other types of high-risk HPV were more common in patients with low-grade lesions and in those treated with brachytherapy. When considering colposcopy as the standard for diagnosing vaginal dysplasia, HPV DNA testing was more sensitive than the PAP test. However, the specificity of the PAP test was higher with no false-positive case. In conclusion, vaginal preneoplastic changes in women post-hysterectomy and receiving radiotherapy for cervical, endometrial, and vaginal cancer represent an HPV-related nosologic entity. Whereas colposcopic examination can detect these preneoplastic lesions, HPV genotyping is a sensitive, inexpensive, and noninvasive method that may complement colposcopy and the PAP test.

Abstract
Human papilloma virus (HPV) is a public health problem as a sexually transmitted disease and as a critical factor in the pathogenesis of various cancers. The clinical manifestations, epidemiology, and virology that are critical to understanding the process of cervical dysplasia and neoplasia are reviewed. A discussion of the cervical transformation zone and the classification of cervical dysplasia and neoplasia leads into the importance of the Papanicolaou smear in prevention of potentially devastating sequelae of this virus. The role of the immune system in the progression of the disease and how it relates to vaccines, as well as treatment and prevention of HPV, are reviewed.

Abstract
BACKGROUND This study used the clinicopathologic profiles of Japanese women younger than 50 years of age with endometrial carcinoma to distinguish the clinicopathologic features of carcinomas of the lower uterine segment (LUS) from those of carcinomas of the corpus mucosa proper (CMP). METHODS Eighty-eight endometrial carcinomas in women younger than 50 years old (25.3%) were selected from our file of 348 Japanese women with endometrial carcinoma. Seventy-two were classified as carcinomas of the CMP and 16 carcinomas of the LUS. A tumor was judged to be a carcinoma of the LUS when it involved a continuous area ranging from the lower corpus to the upper cervix with or without intervention of a portion of uninvolved LUS. RESULTS The mean ages of women with carcinomas of the CMP and LUS were 41.2 and 39.0 years, respectively. In comparison to carcinomas of the LUS, carcinomas of the CMP were more strongly associated with reproductive risk factors including parity (P = 0.01) and polycystic ovary syndrome (P = 0.02). There was no significant difference in body mass index or the incidence of diabetes mellitus and hypertension between women presenting with carcinomas of the CMP and LUS. Histologically, carcinomas of the LUS more frequently showed a high-grade endometrioid tumor (P = 0.02) with deep myometrial invasion (P < 0.01) and were less associated with endometrial hyperplasia (P < 0.01) than those of the CMP. CONCLUSIONS Carcinomas of the LUS occurred predominantly in women younger than 50 years of age and had clinicopathologic features distinct from carcinomas of the CMP in women younger than 50 years of age.
