Background: Breast cancer is one of the common malignancies among women worldwide. Human papillomavirus (HPV) infections have been linked to many human cancers in addition to cervical cancer and one of them is breast cancer.
Objective: To investigate the presence of human papilloma virus type 6 and type 11in breast cancer tissue specimens by in situ hybridization technique.
Patients and Methods: Thirty four formalin-fixed, paraffin embedded tissue blocks from breast cancer patients were obtained from the archives of the pathology laboratory of Al-Yarmouk Teaching Hospital from January 2011 to July 2012. In addition formalin-fixed, paraffin embedded blocks tissue for twenty fibroadenoma of breast were collected and used as control group. In situ hybridization technique was used for the molecular detection of HPV type 6 and HPV type 11.
Results: There were 82.4 % of breast cancer tissues positive for HPV type 6 and 88.2 % were positive for HPV type 11.
Conclusion: The presence of human papillomavirus DNA in most breast carcinoma samples merits further investigation and confirmation by second assay in order to establish the exact role of this virus in the pathogenesis of breast cancer.
Among more than 200 different human papilloma viral genotypes, the association of low oncogenic risk-HPV genotypes have been recognized with a variety of oral, oropharyngeal, nasopharyngeal benign tumors as well as non-neoplastic polyposis and papillomas and adenoid hypertrophy. This prospective case- control study aims to determine the rate of DNA detection of HPV genotype 6/11 in nasopharyngeal adeno- tonsillar tissues from a group of patients subjected to adenoctomy for adenoid hypertrophy . A total number of nasopharyngeal adeno-tonsillar tissue specimens from pediatric patients with adenoid hypertrophy were enrolled; 40 nasopharyngeal adeno-tonsillar tissues from patients with adenoid hypertrophy, and 20 normal nasal tissue specimen
... Show MoreBackground: The role of Human papillomaviruses (HPV) in the etiology of ovarian cancer remains unclear and the results are controversial. Several studies have verified the presence of HPV DNA in both malignant and benign ovarian tumors.
Objectives: Determine the percentage of detection of HPV high (16&18) and low risk types (6&11) in surface epithelial ovarian carcinoma compared to benign and control groups.
Materials And Methods: Molecular detection and genotyping of HPV DNA were performed in 76 ovarian tissue blocks by using in situ hybridization (ISH) technique for detecting and localization of high risk HPV (16 and 18) and low risk HPV (6&11) types.
Results: The presence of ISH signals fo
Background: Epstein Barr Virus (EBV) infection has been implicated in pathogenesis of several types of carcinomas such as nasopharyngeal carcinoma, gastric cancer and bladder cancer and has recently been associated with breast cancer.
Objective: To evaluate the relations between Epstein Barr virus-encoded small RNA (EBER) and breast cancer.
Methods: Twenty two cases of breast cancer were retrieved from the Al-Kadhimiya Teaching Hospital in Baghdad. Clinical data were analyzed from the medical records and formalin fixed, paraffin embedded tumor tissue were examined by Chromogeneic in situ hybridization (ISH) technique for the detection of EBER.
Results: The expression of EBER in tissues patients with breast cancer in the present
Background: Earlier reports related the presence of Mouse Mammary Tumor Virus -like gene sequences to human breast carcinoma. Mouse Mammary Tumor Virus -like gene is a retrovirus, namely, a virus containing reverse transcriptase which transcript its RNA to DNA in a process that enables genetic material from the retrovirus to become a part of the genes of an infected cell permanently. The virus that found in women was designated as Human Mammary Tumor Virus by the authors, who have investigated the presence of Human Mammary Tumor Virus sequences in a many human breast tissues and in many countries.
Objectives: Detect HMTV genome in Iraqi women of breast cancer.

... Show MoreBackground: Molecular DNA hybridization has confirmed more than 120 different human papilloma virus (HPV) genotypes. A small group of them have high- risk oncogenic potential. Many studies have described an association of such high risk-HPV genotypes with a variety of oral lesions including squamous cell carcinoma, leukoplakia, and lichen planus.
Materials and Methods: A total number of 42 tissue specimens, representing 27 patients with oral lichen planus and 15 apparently-healthy oral tissues, were included in this study. The molecular methods for HPV detection and genotyping were performed by in situ hybridization(ISH) using cocktailed- and specific high- risk HPV DNA probes, respectively.

Background: Breast cancer (BC) is a type of cancer originating from breast tissue, Lipid profile seems to influence the development of female breast cancer, especially in the presence of an increased body mass index so.
Objective: to explore the status of lipid profile in women with breast cancer.
Subjects and methods: the present study is a cross-sectional study (2010/2011) done at Al-Yarmouk Teaching Hospital. Includes measurement of LP in sera of postmenapausal newly diagnosed women with BC in comparison with healthy control women. This measurement was done using colorimetric method. In The results of this study include a total of 100 patients with BC were involved in this study, they were classified as newly diagnosed postmenop
Background: Transitional cell carcinomas (TCC) of the bladder are a major health problem. Recently, some studies link high risk Human papilloma viruses' type 16 and type 18 with bladder carcinoma.
Materials and methods: Fifty formalin fixed, paraffin embedded tissues with TCC of the bladder from Specialized Surgical Hospital in Baghdad were included in this study. In addition, ten
apparently normal bladder autopsies were collected from the Forensic Medicine Institute Archives and used as control group. Tissue blocks were sectioned and sticked on charged slides and used for the detection of HPV-16 and HPV-18.
Results: The expression of HPV-16 and HPV-18 DNA signals in TCC of the bladder tissues in the&nbs
Background: Breast cancer is a highly heterogeneous disease globally. Trace elements such as copper and zinc have a role in many biochemical reactions as micro source, their metabolism is profoundly altered in neoplastic diseases especially breast cancer which is ranked as the first of female cancers
Objective: The aim of the present study is to study the impact of body mass index and some trace elements in Iraqi women with breast cancer.
Patients and methods: The group of the study consisted of 25 breast cancer patients; their age range was (25–65) years recruited from the Al-Kadhimia Teaching Hospital and 25 apparently healthy women age matched, over a period of 6 months from January 2015 until June 2015. After the diagnosis wa
Back ground: Epstein- Barr virus (EBV) is a ubiquitous in that infecting more than 90% of adult population worldwide. Recently, EBV has been linked to the development of variety of human malignancies. P53 gene is mutated in more than 50% of human cancers. Cell cycle dysregulation, measured by p53 protein expression, and latent EBV infection are important in the pathogenesis of Non-Hodgkin’s lymphomas.
Objective: To analyze the distribution and impact of concordant p53 expression and latent EBV infection on a group of B & T cell types of NHL.
Materials and Methods: Forty (40) formalin-fixed, paraffin embedded tissue blocks were obtained from lymph nodes biopsies related to patients with NHL.
In addition, biopsies of twenty
Background: Obesity rates are increasing day by day affecting all populations at different ages. The most prevalent kind of cancer among women worldwide is breast cancer, with increasing rates in the present time and in the future. Substantial connections between obesity and breast cancer are demonstrated. Elevated circulating levels of insulin and interleukin-6 have a substantial link to obesity and breast cancer development.
Objective: This study aimed to examine the serum levels of insulin and interleukin-6 in postmenopausal breast cancer patients and to study the connection between these biomarkers and breast cancer development.
