    • <p>The results of a treatment method on adenocarcinoma corpus uteri stage I-II based upon cytometrically measured DNA ploidy are presented. All patients had a simple hysterectomy. Adjuvant treatment (postoperative vaginal brachytherapy) were given only, to those patients with non-diploid tumours regardless of stage and grade. A total of 1,634 women with endometroid adenocarcinoma corpus uteri stage I-II were included where 1,396 patients were followed-up for at least 5 years or until death and the remaining 238 patients were followed-up 3.5-5 years or until death. By using cytometry only, we identified a low-risk group comprising 83% of the patients (with 52% dead from their disease) and a high-risk group of 17% (with 15.7% dead from their disease). By using grade only (well- and moderately differentiated vs poorly differentiated), the low-risk group comprised 87% of the patients (with 4.6% dead from their disease) and the high-risk group 13% (with 13% dead from their disease). By using stage only (stage Ia and Ib vs stage Ic and II), the low-risk group comprised 78% of the patients (with 3.6% dead from their disease) and the high risk group 22% (with 14.5% dead from their disease). By combining these prognostic parameters, we were able to identify small subgroups with increased mortality rates in need of adjuvant therapy. As ploidy still had a strong prognostic strength regardless of given adjuvant radiotherapy, we do not believe that this treatment was effective. We therefore recommend future research to be directed toward cytostatics as an alternative adjuvant treatment.</p>

  • Progress of tissue injury in appendicitis involves the serine proteases uPA and PAI-1
  • 2009
  • Ingår i: Scandinavian Journal of Gastroenterology. - 0036-5521 .- 1502-7708. ; 44:5, s. 579-584

    • <p>OBJECTIVE: Serine proteases and the matrix metalloproteinases (MMPs) are key factors in the proteolytic cascade and participate in extracellular matrix (ECM) degradation. Fibrinolytic activators and inhibitors may have an effect on inflammatory cells, thereby modulating the inflammatory response. It is reasonable to assume that they may be implicated in the tissue injury in acute appendicitis that subsequently leads to appendix perforation. The purpose of this study was to investigate the expression and distribution of urokinase-type plasminogen activator (uPA) and plasminogen-activator inhibitor type 1 (PAI-1) in appendicitis. MATERIAL AND METHODS: Expression of uPA and expression of PAI-1 were measured in tissue specimens from patients with appendicitis (n=30) and in control specimens (n=9), using the quantitative ELISA technique. Distribution of enzymes was studied with immunohistochemistry. The uPA and PAI-1 levels in the subgroups of appendicitis and controls were compared. RESULTS: The overall expressions of uPA and PAI-1 were greater in appendicitis than in control specimens (p &lt;0.001 and p&lt;0.0001, respectively). Expressions of uPA and PAI-1 in phlegmonous (n=15), gangrenous (n=6) and perforated appendicitis (n=9) were all higher than those in controls (n=9), (p&lt;0.01). Moreover, the PAI-1 level was elevated in perforated appendicitis compared with phlegmonous appendicitis (p&lt;0.01). uPA staining was observed in connection with vascular endothelial cells and the serosa stained intensely in specimens from perforated appendicitis. CONCLUSIONS: The expression of uPA and especially the over-expression of PAI-1 seem to correlate to the progression of local inflammatory response in acute appendicitis.</p>
