Various carcinogenic metabolites, including catechol estrogens, play a role in malignant transformation. An enzyme that is capable of neutralizing the genotoxic effects of these compounds is catechol-O-methyltransferase (COMT). A variant form of this enzyme has been shown to reduce its activity by up to 4-fold; thus, we hypothesize that single nucleotide polymorphisms of the COMT gene can be a ...
Background: p57, a cyclin-dependent kinase inhibitor, is considered to be a candidate tumor suppressor gene that has been implicated in Beckwith-Wiedemann syndrome and sporadic cancers. In addition, decreased expression of p57 protein has been frequently observed in pancreatic, lung, breast, bladder, gastrointestinal tract and prostate cancers. However, p57 gene mutations are rare in these canc...
BACKGROUND Glutathione-S-transferases (GSTs) are active in the detoxification of wide variety of endogenous or exogenous carcinogens. The genetic polymorphisms of GSTM1 and GSTT1 genes have been studied earlier to evaluate the relative risk of various cancers. AIM, SETTING AND DESIGN: In the present study, we examined the association of the GSTM1 and GSTT1 gene polymorphisms with sporadic prost...
Background and Aim: The current study aimed to investigate the state of health information supply and demand on prostate cancer among Iranian medical researchers and Iranian web users during 2011 to 2015. The purpose of this study, based on infodemiology indicators, was to investigate the alignment of health information supply and demand on prostate cancer among Iranian medical researchers and ...
conclusions psa, psa density, and gleason score should be considered together in order to more accurately predict the adverse pathologic features of prostate cancer. methods we conducted a cross-sectional study of 105 patients with localized prostate cancer who underwent radical prostatectomy between 2006 and 2013. we recorded gleason scores and psa levels, in addition to the results of patholo...
background: metastatic prostate cancer is one of the most important cancers among men worldwide. androgen ablation therapy can be used in treatment of these patients; however, most will progress to metastatic hormone-refractory prostate cancer. in this regard, docetaxel has been approved to treat metastatic hormone-refractory prostate cancer in the united states. in this study, we aimed to inve...
Background: Prostate cancer is the most common cancer and the second cause of cancer mortality in men. Although histopathological examination is the gold-standard for its diagnosis, tendency toward less invasive methods is growing. The purpose of this study was to evaluate the relationship between choline plus creatine- to-citrate ratio in magnetic resonance spectroscopy (MRS) with the invasion...
Objective(s): The aim of this study was to analyze detection rates and effectiveness of 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) cancer screening program for prostate cancer in Japan, which is defined as a cancer-screening program for subjects without known cancer. It contains FDG-PET aimed at detection of cancer at an early stage with or without additional screening tests ...
Background and purpose: Prostate cancer is one of the most prevalent diseases among men. The role of heredity in prostate cancer has been proved by epidemiologic studies. By utilization of prostate specific antigen (PSA) and digital rectal exam (DRE) we could diagnose the disease before the clinical manifestation and implement screening programs. The purpose of this study was to screen the pros...
Poly(ADP-ribose)polymerase inhibitors (PARPis) have shown promising activity in patients with BRCA1/2 mutation-associated (BRCA1/2(MUT+)) ovarian and breast cancers. Accumulating evidence suggests that PARPi may have a wider application in the treatment of sporadic high-grade serous ovarian cancer, and cancers defective in DNA repair pathways, such as prostate, endometrial, and pancreatic cance...
