Association Between Integrin Expression and Prognosis in Localized Prostate Cancer

BACKGROUND. Integrins and other adhesion molecules are essential for maintaining the epithelial phenotype. Some studies have reported correlations between abnormalities in their expression and carcinogenesis, but their role in prostate cancer is unclear. Our aim was to study the expression profile of integrins in surgical specimens of prostate cancer and associate their expression patterns with patient outcomes. METHODS. We selected 111 patients with localized prostate cancer who had undergone radical prostatectomy. Of these patients, 60 had no tumor recurrence after a median follow-up of 123 months. Integrin expression was evaluated by immunohistochemistry in a tissue microarray containing two tumor samples per patient. A semiquantitative analysis was employed. We measured the association between the expression of eight integrins and tumor recurrence. RESULTS. Multivariate analysis showed that expression of alpha 3 and alpha 3 beta 1 was related to worse outcome. When alpha 3 expression was strong and alpha 3 beta 1 expression was positive, the odds of recurrence were 3.0- and 2.5-fold higher, respectively. Only 19% and 28% of patients were recurrence-free in a mean period of 123 months of follow up when their tumors showed strong alpha 3 or positive alpha 3 beta 1 immuno-expression, respectively. CONCLUSIONS. We have shown that the expression of integrin alpha 3 beta 1 was independently associated with tumor recurrence after radical prostatectomy, suggesting that this integrin is a potential prognostic marker.

Comentários a uma sentença anunciada : o processo Lula

“Comentários a uma sentença: o Caso Lula” é talvez o mais importante documento jurídico publicado no Brasil em décadas. A presente coletânea de artigos nasceu de um movimento espontâneo e bastante significativo de juristas brasileiros e estrangeiros que examinaram cuidadosamente a sentença proferida no âmbito do processo que tramitou na 13ª Vara Federal de Curitiba, no caso que ficou conhecido na mídia como o do “tríplex do Guarujá”. <br>De la presentación de Geraldo Prad

Comentarios a una sentencia anunciada : el proceso Lula

El centenar de textos que conforman este libro -escritos por un movimiento de prestigiosos/as juristas y abogados- desgranan el procedimiento al que fue sometido Lula. En la opinión de las y los autores de los artículos las normas no fueron observadas, y su inobservancia llevó a que se dictaminase una decisión injusta. Frases del estilo "Voy a tomar una decisión revolucionaria, dejando de lado la ley, porque por la ley no se puede condenarlo de ninguna manera”, dichas en los juicios por las más altas autoridades judiciales militares y civiles, hoy son conocidas gracias a quienes se abocaron al trabajo de escuchar los audios de aquellas sesiones, nutriendo las reflexiones que argumentan sobre el imperativo de la hora: restablecer el estado de derecho y absolver al presidente Lula Da Silva
