results like other cancers, prostate cancer is caused by an accumulation of genetic alterations in a cell that drives it to malignant growth. specific genes and gene alterations have been suggested to play a role in its development and progression. aneuploidy, loss of heterozygosity, gene mutations, hypermethylation and inactivation of specific tumour suppressor genes such as gstpi, apc, mdr1, ...

background: prostate cancer is the most common malignancy among the male population in the united states and the 3rd most common non-skin cancer among men in iran. its prevalence has shown a rising trend in recent decades. the aim of this study was to report the epidemiological features of prostate cancer in patients referred for prostate biopsy in the south of iran and to evaluate the accuracy...

background: prostate specific antigen (psa) is a protein currently used in vconjunction with the digital rectal examination to detect and guide management of prostate cancer. there are several causes of increase in serum psa including urological manipulations, medications, prostatic diseases, prostate cancer, prostate inflammation or infection, etc. some studies had reported cystoscopy to cause...

conclusions results showed that whereas knowledge by itself cannot guarantee men’s participation in prostate cancer screenings, perceived barriers can play an important role in discouraging men from cancer screening participation. therefore, designing programs to address these barriers is very important. results the most common barriers to screening for prostate cancer were a lack of knowledge ...

conclusions our study showed that microrelin is as effective as diphereline in reducing psa and testosterone and can be recommended to initiate medical castration in patients with pc. results each group contained 40 patients. in group a, psa was reduced from 75.78 ± 72.43 ng/ml to 1.93 ± 1.40 ng/ml after 6 months and testosterone was reduced from 3.50 ± 1.12 nmol/l to 0.81 ± 0.05 nmol/l. there ...

to investigate and compare the infectious and non-infectious complications of single-dose versus multiple-dose antibiotic therapy for trans-rectal ultrasound (trus)-guided biopsy of the prostate. patients were enrolled in a prospective randomized study that was designed to investigate the effects of single-dose versus multiple-dose antimicrobial prophylaxis regimen mainly on asymptomatic bacter...

introduction: prostate cancer is one of the most common cancers among males and the second factor resulting to death due to cancer among them.(1) the median age of its diagnosis is 65 years. the initial treatment includes androgen ablation or orchiectomy.(2, 3) in case of patient’s hormone refractory, chemotherapy would be substituted. the objective of this study is the consideration of intermi...

the tp53 gene is one of the most frequently mutated genes amongst human malignancies, particularly tp53 codon 72 polymorphism. furthermore, an association between the tp53 codon 72 variants and prostate cancer has been reported in several studies. although some studies have indicated an association between the tp53 arg/arg variant and an increased risk for prostate cancer, other studies have sh...

background: we aimed to value the usefulness of free to total prostate-specific antigen and prostate-specific antigen (psa) density for prostate cancer in the patients with psa levels of 4.0 ng/ml or less. methods: a total of 343 subjects with psa levels of 4.0 ng/ml or less were biopsied. all patients were divided into four groups according to the psa levels: 0 to 1.0 ng/ml, 1.1 to 2.0 ng/ml, ...
