چکیده
Abstract Prostate cancer occures in male, especially over 65 year old. It develops usually in the peripheral zone, less commonly in central or transitional ones. The neoplasm screening bases on clinical digital rectal examination and serum level of prostate-specific antigen (PSA). Among patients with increase PSA concentration, transrectal ultrasound usually with multiple core biopsies is performed. The obtained bioptates are histologically evaluated using Gleason's grading system. However, the method of choice to examine the entire pelvis is a magnetic resonance. According to current principles, the obtained images are evaluated using five-step PI-RADS classification based on T2-weithed, diffusion weighted and dynamic contrast enhancement images. Spectroscopy is also suggested especially in case of prostatic carcinoma. Such procedures allow precise evaluation of cancer progression, and is helpful in treatment planning and response monitoring.

The hallmarks of castration-resistant prostate cancers. - PubMed - NCBI
Prostate cancer has become a real public health issue in industrialized countries, mainly due to patients' relapse by castration-refractory disease after androgen ablation. Castration-resistant prostate cancer is an incurable and highly aggressive terminal stage of prostate cancer, seriously jeopardizing the patient's quality of life and lifespan. The management of castration-resistant prostate...
متن کاملDairy intake in relation to prostate cancer survival. - PubMed - NCBI
Dairy intake has been associated with increased risk of advanced prostate cancer. Two US cohort studies reported increased prostate cancer-specific mortality with increased high-fat milk intake. We examined whether dairy and related nutrient intake were associated with prostate cancer progression in a Swedish patient population with high dairy consumption. We prospectively followed 525 men with...

Current standard imaging techniques are insufficient to reliably detect lymph node metastases in prostate cancer. Recently ligands of PSMA (prostate specific membrane antigen) were introduced in PET (positron emission tomography) of prostate cancer. Thus the aims of this retrospective analysis were to 1) investigate the diagnostic efficacy of (68)GaPSMA-PET imaging for lymph node staging in pat...
