Background and Objective: Prostate cancer is one of the most common cancers of the urinary system. The most used method for diagnosis is transrectal ultrasonography-guided biopsy. The purpose of this study is a statistical analysis with the aim of reducing unnecessary biopsies based on individual, geographical and genetic patterns in our region. Methods: The medical records of all patients who...
Background: Different studies assessed the role of inflammation in malignancy of different organs. Prostatitis has been suggested as a cause of cancer and BPH. Till now, more than 100 types of human Papilloma virus (HPV) are recognized including low and high-risk groups for carcinogenesis. Among them HPV-16 and HPV-18 have shown further association with cancer. Regarding the pr...
The loss of cell cycle control is believed to be an important mechanism in the promotion of carcinogenesis. CDKN1B (p27) belongs to the Cip/Kip family and functions as an important cell cycle gatekeeper. Several lines of evidence from clinical studies and laboratory experiments demonstrate that CDKN1B is an important tumor suppressor gene in prostate cancer etiology. In addition, a case-control...
Background: Prostate cancer is currently the third malignant disease in Iran and fifth common cancer worldwide. The aim of this study was to determine the expression of GPRC6A, E.cadherin, and ZEB1 genes in prostate cancer in comparison with benign tumor. Since early detection of cancer plays an important role in treatment, this study aims to identify the role of GPRC6A, E.cadherin and ZEB1 gen...
BACKGROUND The EphB2 gene was recently implicated as a prostate cancer (PC) tumour suppressor gene, with somatic inactivating mutations occurring in approximately 10% of sporadic tumours. We evaluated the contribution of EphB2 to inherited PC susceptibility in African Americans (AA) by screening the gene for germline polymorphisms. METHODS Direct sequencing of the coding region of EphB2 was p...
Prostate cancer (PCa) is the most common non-skin cancer and the second leading cause of cancer death among men in the world. Growth, maintenance and the expression of genes involved in the production of steroids, may alter the susceptibility of prostate cancer. One such gene, CYP1B1 (cytochrome P450, family 1, subfamily B, polypeptide 1) is involved in the activation of many carcinogens and i...
background : insulin-like growth factor-1 can act in both an autocrine and paracrine manner to promote normal growth and malignant cellular proliferation. the importance of this factor as a major regulatory peptide has been established for cells, in vitro and in vivo. however, the role of serum insulin-like growth factor-1 levels in the etiology of benign prostatic hyperplasia and prostate canc...
Background & Aims: Prostate cancer (PCa) is the second most common cancer in men worldwide. The identification of sensitive and specific biomarkers in tissue and serum is of utmost importance to reduce the mortality of prostate cancer. Since that, early detection of cancer has an important role in treatment, in this study we tried to identify genes that could potentially effective in early...
Prostate-specific membrane antigen (PSMA) is a type II transmembrane protein, which is anchored in the cell membrane of prostate epithelial cells. It is highly expressed on prostate epithelial cells and strongly up-regulated in prostate cancer. Although, 177Lu-PSMA has been recently introduced for radionuclide therapy of metastatic castration-resistant prostate cancer (mCRPC) with co...
BACKGROUND Reliable estimates on the age of onset between familial and sporadic cancers are important for etiological understanding and clinical practice. Specific studies on the age of onset of familial cancer compared with sporadic cancer are less common than studies on familial risks and these are almost lacking for rare cancers. MATERIALS AND METHODS The Swedish Family-Cancer Database was...
