Prostate cancer has come to share the oncological centrestage among male cancers. The availability of Serum Prostate Specific Antigen, PSA, as a marker has encouraged it's use to diagnose both cancer and cancer recurrence. Some clarity is required about its precise role in clinical practice. The available literature on Prostate Specific Antigen was reviewed; Articles were reviewed for content, ...
More than a decade ago, several investigators found serum PSA levels in cancer-free men to correlate directly with age and prostatic volume. This provided the basis for the establishment of age-specific reference ranges for PSA constituting an attempt to improve sensitivity and specificity of serum PSA as a marker for prostate cancer. Differing age-specific reference ranges for PSA were establi...
Cardiovascular disease is one of the leading causes of death in psoriatic arthritis (PsA). Pathogenesis of accelerated atherosclerosis in PsA remains to be elucidated. Endothelial dysfunction (ED) often precedes manifesting atherosclerosis. This study aims to assess carotid intima-media thickness (CIMT), a marker of atherosclerosis in PsA, in context of markers of inflammation and vascular func...
We introduce a continuous stochastic model for the prostate-specific antigen (PSA) levels following radiotherapy and derive solutions for the associated partial differential (Kolmogorov-Chapman) equation. The solutions describe the evolution of the time-dependent density for PSA levels which take into account an absorbing condition along the boundary and various initial conditions. We include i...
OBJECTIVE To examine the prevalence of subclinical atherosclerosis in patients with psoriatic arthritis (PsA) compared with healthy controls, and to identify clinical and biologic markers for atherosclerotic disease in this patient population. METHODS Subclinical atherosclerosis was defined as the average of intima-media thickness (IMT) measures in the common carotid artery, bifurcation, and ...
PURPOSE To evaluate the predictive performance of various parameters derived from volume-adjusted prostate-specific antigen (PSA) values in detecting prostate cancer (PCa) and high-grade (Gleason score≥7) PCa according to treatment with a 5α-reductase inhibitor (5ARI). METHODS The results of 3,520 prostate biopsies performed between May 2006 and January 2013 were retrospectively assessed. Wit...
زمینه و هدف:psa (prostate specific antigen) یک تومور مارکر بسیار خوب است ولی اختصاصی سرطان پروستات نیست. در این پژوهش سعی شد psa تعدیل شده tz (transitional) در بررسی تشخیصی سرطان پروستات با دانسیته psa مقایسه گردد. مواد و روش¬ها: در این مطالعه در 100 بیمار (50 بیمار مبتلا به سرطان پروستات و 50 بیمار مبتلا به هیپرپلازی خوش خیم پروستات) با استفاده از سونوگرافی ترانس رکتال و مقادیر آزمایشگاهیpsa ،...
