The role of p16(INK4A) as a marker of HR-HPV and in the diagnosis of CIN has been well established, but its predictive value in the clearance of the virus after CIN treatment and its use as a prognostic marker of cervical cancer has not been studied. A series of 302 archival samples, including 150 squamous cell carcinomas (SCCs) and 152 CIN lesions, were(More)
BACKGROUND As a part of our search for oncogenic viruses as potential etiological agents in human malignancies, our studies on human papillomaviruses (HPV) were extended to analysis of the 3 polyomaviruses (SV40, BKV and JCV) in colorectal carcinomas. PATIENTS AND METHODS Archival tumour samples from 71 patients with colorectal cancer were analyzed for(More)
Invasive endocervical adenocarcinoma represents on average 15% of cervical carcinomas and it is associated with the human papillomavirus infection high risk types 16 and 18 in most cases. Its detection has some special features compared to squamous cell carcinoma; glandular precancerous lesions are less known and only adenocarcinoma in situ is diagnosed by(More)
Metastases from mammary carcinoma represent the principal cause of exitus in 45% of subjects dead from this neoplasia. Also if they are not frequent, uterine metastases from mammary carcinoma are not very rare to find at the autopsy (2-15% as various Authors report). In this study, the Authors present 17 cases (1 bioptic and 16 autoptic cases) of uterine(More)
OBJECTIVE One of the factors leading to an invasive phenotype is the nm23 family of metastases-associated genes. Of the six known members, nm23-H1 is the most frequently studied potential anti-metastatic gene in cervical cancer. However, the possible molecular links to oncogenic human papillomavirus (HPV) are completely unexplored as yet. MATERIALS AND(More)
Twelve cases of metastatic tumors to the female breast are reported. Ten of them were incidentally discovered at autopsy; two cases were diagnosed ante mortem but one was misinterpreted as primary. The patients' mean age was 58 years. The metastasizing tumors included cutaneous malignant melanoma (four cases); ovarian, renal and gastric adenocarcinoma (two(More)
OBJECTIVES In women with HIV-associated immunosuppression, HPV infections have an increased risk of progression to high-grade cervical intraepithelial neoplasia (CIN). With the HAART-induced prolonged survival and more protracted clinical course of AIDS, progression of CIN to cervical cancer (CC) has become a clinically relevant issue, and the mechanisms(More)
OBJECTIVE Oncogenic human papillomaviruses (HPVs) are the etiological agents of cervical cancer. Different cofactors might be needed for malignant transformation, but they still remain elusive. METHODS To delineate the role of Chlamydia trachomatis (CT) and herpes simplex virus type 2 (HSV2) in HPV-positive cervical intraepithelial neoplasia (CIN) lesions(More)
OBJECTIVE Matrix metalloproteinase-2 (MMP-2) and its tissue inhibitor (TIMP-2) are important regulators of cancer invasion and metastasis. Their associations to high-risk (HR) human papillomavirus (HPV) in cervical intra-epithelial neoplasia (CIN) and cervical cancer (CC) are unexplored and their prognostic significance in CC remains controversial.

BACKGROUND Three novel polyomaviruses have been recently discovered: KI, WU and MC polyomaviruses. Their role in human pathology is debated while tissue tropism and site of latency remain unknown. OBJECTIVE To test the hypothesis that KI, WU and MC polyomaviruses can infect human tonsils. STUDY DESIGN Archival paraffin-embedded tonsils from 91 patients(More)
