    Abstract Introduction/objective: Margin positivity has been a well described adverse prognostic factor in patients undergoing radical prostatectomy. Previous studies with regards to predictors of margin positivity after prostatectomy have primarily focused on the retropubic or robotic approach. We sought to examine the predictors of margin positivity in a contemporary series of men undergoing radical perineal prostatectomy (RPP).
    Materials and methods: We reviewed the records of 103 patients who underwent RPP at our institution from July 1998 until May 2008. A positive surgical margin (PSM) was defined as the presence of cancer cells at the inked margin of the… More >

    Relation between the tumor necrosis factor-α (TNF-α) gene and protein expression, and clinical, biochemical, and genetic markers: age, body mass index and uric acid are independent predictors for an elevated TNF-α plasma level in a complex risk model

    European Cytokine Network, Vol.15, No.2, pp. 105-111, 2004

    Abstract Background: Tumor necrosis factor-alpha (TNF-α) has been implicated in the pathogenesis of numerous complex diseases. The plasma level of this pro-inflammatory cytokine is associated with a variety of different risk factors, but little is known about the genetic background and the complex interactions. Methods: in this clinical study, correlations were studied between plasma levels of circulating TNF-α protein (ELISA), its mRNA expression in monocytes (RT-PCR) and genetic variants of TNF-α gene (SSCP), with several diseases, including obesity, atherosclerosis, diabetes mellitus, hypertension, as well as risk factors such as age, gender, inflammatory markers, the coagulation/fibrinolysis balance,… More >
