Résumé
Abstract Purpose: To investigate the place of the transcription factor nuclear kappa B (NF-kB), which is a marker of chronic inflammation, in the etiology of the ovarian carcinoma. Methods: NFkB analysis with the immunohistochemical method has been performed. To evaluate immunohistochemical NF-kB expression in the ovarian tissue, the H-score method. H-score = ∑ Pi (i+1), where ''Pi'' is the percentage of stained cells in each intensity category (0-100%) and ''i'' is the intensity indicating weak (i=1), moderate (i=2) or strong staining (i=3). Results: It has been seen that, the mean H score is statistically significantly higher in the patient group with serous and musinous adenocarcinoma diagnosis than the two other patient groups (p<0.005). Conclusions: Factor nuclear kappa B is an important mediator that acts in the chronic inflammation. The highest expression rates are determined by the immunohistochemical method in the ovarian cancer group.

BACKGROUND: Involvement of the pancreas in Von Hippel-Lindau disease that is a tumor predisposing syndrome mentioned in literature with some morbid and mortal progression. AIMS: For evaluation the faith of the pancreatic involvement in VHL disease we analysed our patient population with VHL disease. MATERIALS AND METHODS: 12 of the 56 patients that were evaluated in our institute with the diagnosis of Von Hippel-Lindau disease had pancreatic involvement. They are periodically examined for 5 years follow up period. Their retrospective analysis was accomplished. RESULTS AND CONCLUSIONS: Pancreatic involvement in our patient population disclosed lesions that were multicysts or serous cystadenomas. During follow up period, we did not observe significant morbidity related to pancreatic involvement. Repeated radiological examination of pancreatic lesions disclosed insignificant modifications such as slight increase or decrease in size. Whereas we considered morbidity and mortality related to renal and central nervous system pathologies in VHL disease. Shortly, even pancreatic involvement in VHL disease requires close clinical follow up, morbidity and mortality in this case is not severe as in renal and the central nervous system involvement.
