ABSTRACT Emerging insights underline a link among chronic inflammation and endothelial activation with benign prostatic hyperplasia (BPH) and prostate cancer (PCa). We aim to investigate whether specific plasma markers of inflammation and endothelial activation allow to discriminate BPH and PCa.
Fifteen patients affected by BPH, 15 by PCa and 15 controls, were enrolled. Interleukin-6 (IL-6), CD40 ligand (CD40L), endothelial-selectin (E-selectin), platelet-selectin (P-selectin), vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1) were measured.
In systemic blood samples, IL-6 has been found increased in patients affected by BPH (4.25 ± 0. pg/mL) and PCa (5.08 ± 0.24) respect to controls (2.62 ± 0.34; p < 0.05). CD40L was higher in BPH (4.25 ± 0.65 ng/mL; p < 0.05) than in control (2.31 ± 0.20) and PCa group (2.60 ± 0.56). E-selectin, P-selectin and VCAM-1 did not show any significant difference. Higher levels of ICAM-1 were detected in patients with PCa (573.04 ± 52.23) and BPH (564.40 ± 74.67) than in the controls (215.30 ± 11.53 ng/mL; p < 0.05). In local blood samples, IL-6 has been found significantly increased in PCa in comparison with patients with BPH; there was no difference in CD40L, E-selectin, P-selectin, VCAM-1 ed ICAM-1.
Changes in inflammation and endothelial activation markers may be not considered to be of value in discriminating BPH and PCa.

    ABSTRACT: RESUMEN El cáncer de próstata es la neoplasia no cutánea que afecta con mayor frecuencia a los hombres en todo el mundo. Existe evidencia que señala un papel de la inflamación crónica en el desarrollo de distintas neoplasias en humanos, entre ellas el cáncer de próstata. Esta asocia-ción fue sugerida hace mucho tiempo por la observación de infiltrados en muestras de tejido prostático de pacientes con cáncer y, más recientemente, por los altos niveles de citocinas proinflamatorias en el suero de pacientes con esta enfermedad. Muchos estudios han determi-nado la asociación de ciertos polimorfismos de base única en genes asociados a inflamación con el riesgo de desarrollar cáncer de próstata. En los últimos años se han descrito los efectos de moléculas inflamatorias sobre el comportamiento biológico de esta neoplasia; se destacan entre ellos el potencial de inducir la proliferación de células cancerígenas y la des-diferen-ciación de células del estroma. La influencia de la inflamación en el desarrollo y avance del cáncer de próstata se ha convertido en un asunto de interés debido al potencial diagnóstico y terapéutico de su uso. Se espera que en el futuro una mejor comprensión biológica de esta asociación lleve a una explotación práctica de su utilidad clínica.

    ABSTRACT: A more specific and early diagnostics for prostate cancer (PCa) is highly desirable. In this study, being inflammation the focus of our effort, serum protein profiles were analyzed in order to investigate if this parameter could interfere with the search of discriminating proteins between PCa and benign prostatic hyperplasia (BPH).

    ABSTRACT: Benign prostatic hyperplasia (BPH) and prostate cancer (PCa) are chronic conditions, which are hormone-dependent and epidemiologically associated with prostate inflammation. As a large number of studies have demonstrated, the stimulation of T-cells at the level of prostatic chronic inflammatory infiltrates is followed by stromal and epithelial cell proliferation. The aim of this review is to present the actual level of knowledge in the field of prostatic immune response and chronic inflammation, and to analyze the relationships between chronic inflammation and BPH/PCa. The most studied prostatic inflammation biomarkers detected in biological fluids are also presented, together with their potential roles in the diagnosis and prognosis of prostatic disease.
