Genomic integration of high-risk human papilloma virus in the nucleus of cervical epithelial mucosal cells leads to epithelial dysplasia. The aim of this study was to determine the relevance of correlation between epithelial survivin expression and the degree of human papilloma virus (HPV)-induced cervical epithelial dysplasia, and to establish the significance of morphometric analysis of the nuclear area in the assessment of the degree of cervical dysplasia. This retrospective study included 99 women with primary, previously untreated lesions, and colposcopic findings indicating dysplasia, in whom a cytological test by Papanicolaou method was interpreted according to the Bethesda criteria as lowgrade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL), and atypical squamous cells of undetermined significance (ASCUS). We performed human papilloma virus (HPV) typing by PCR for evidence of viruse types 16, 18, 31, 33. After biopsy of the cervical mucosa, we performed hematoxylin-eosin (H-E) and Periodic Acid Schiff (PAS) staining, and immunohistochemical and morphometric analysis of tissue samples. The control group consisted of 12 women without dysplasia and without a verified infection of cervical high-risk HPV. A high statistical correlation between the degree of dysplasia and expression of survivin was found in patients with different types of cervical dysplasia (p = 0.003). We observed a high statistical difference between the area of nuclei at different degrees of cervical dysplasias (p = 0.000). The high-grade cervical dysplasia had a more than 2-fold higher level of ranking in comparison to low-grade dysplasia, and a more than 10-fold higher ranking than the control group without cervical dysplasia.

Background and aim. HPV (Human Papilloma Virus) infection represents a necessary condition for cervical carcinogenesis. The purpose of this study was to evaluate the efficiency of HPV testing using an immunohistochemical staining kit with implications upon both diagnosis and treatment of cervical intraepithelial neoplasia (CIN).Methods. Seventy-nine patients and eighty-six controls were enrolled in the study. Each patient had completed a physical examination, gynecological examination with cervical sampling using a liquid-based cytology system and also colposcopy. The cervical samples were analyzed according to Bethesda terminology and HPV-HR immunohistochemical staining was performed. In all the patients with high-grade lesion a surgical excision procedure was performed followed by pathological examination of the specimen. The collected data were analyzed using statistical software.Results. The colposcopic examination has detected acetowhite modifications of the cervical epithelium in 47% of patients with ASC-US (Atypical squamous cells of undetermined significance) in 71% of patients with LSIL (Low grade squamous intraepithelial lesion) and in 100% of patients with HSIL ( High grade squamous intraepithelial lesion). The biopsy confirmed the diagnosis of LSIL in 27% of biopsy specimens in patients with ASC-US and in 79.99% of patients with LSIL respectively. In all patients with HSIL the diagnosis was CIN II or higher. The percentage of HPV-HR (Human Papilloma Virus – High Risk) positivity porportionaly increased with the severity of cytological diagnosis: 30% in ASC-US, 42.86% in LSIL and 75% in HSIL patients. The sensitivity of detection of HPV-HR was 50% with CI 95% [17.45;82.55] for ASC-US, 77.77% with CI 95% [51.91;92.62] for LSIL and 81.81% with CI 95% [58.99;94.00] for HSIL.Conclusion. HPV testing can be an important screening tool for cervical dysplasia. The HPV testing targeting high risk types is indicated for ASC-US and LSIL triage. The present work sustains the idea of introducing HPV testing as a primary  screening tool for cervical cancer.

Numerous risk factors for breast cancer (BC) have been identified. High-risk human papilloma virus (HR-HPV) is the etiological agent of cervical cancer and in some cases of head and neck cancer, specifically oropharyngeal cancer, but the role of HR-HPV in evoking neoplasia in BC is still unclear. In this study, all women above the age of 18 visiting the oncology clinic at Al-Azhar university hospital and Ain Shams specialized hospital between the period of February 2017 and March 2018 were invited to participate. We determined the prevalence of HR-HPV genotypes 16, 18, and 31 in breast tissue samples from 72 women with treatment-naïve BC and 15 women with benign breast lesions (BBL) by quantitative real-time PCR (qRT-PCR) and primer sets targeting the E6 and E7 regions. High-risk human papilloma virus DNA was detected in 16 of 72 (22.2%) BC cases (viral load range = 0.3-237.8 copies/uL) and 0 of 15 women with BBL. High-risk human papilloma virus was detected in 14 of 16 (87.5%), 2 of 16 (12.5%), and 0 of 16 (0%) for genotypes 16, 18, and 31, respectively. Forty-three age-matched healthy Egyptian women were enrolled as controls for assessment of local risk factors that can be used to initiate a strategy of BC prevention in Egypt. Assessment of the risk factors demonstrated that low education level, passive smoking, lack of physical activity, family history of cancer, and use of oral contraception were significant risk factors for BC. In conclusion, our results lead us to postulate that HR-HPV infection may be implicated in the development of some types of BC in Egyptian women. In addition, identification of local risk factors can support practical prevention strategies for BC in Egypt.
