Bcl-2 as prognostic factor in head and neck squamous cell carcinoma
2005
A series of 66 cases of oral squamous cell carcinoma (OSCC) was retrospectively analyzed by immunohisto-chemistry for bcl-2 expression to verify its predictive value for clinical outcome in patients with OSCC. After grouping for bcl-2 expression, OSCCs were statistically analyzed for the variables age, gender, histological grading (G), TNM, staging, recurrence, and overall survival rate. Univariate and multivariate (Cox regression) analyses were performed. Thirty-six OSCC (54.5%) showed expression for bcl-2, whereas 30 (44.5%) were negative. No statistical association was found between bcl-2 expression and any variables considered at baseline. Overall disease-specific survival rate at 72 mo…
Prognostic Implications of the Complement Protein C1q in Gliomas
2019
The contribution of the complement system in the pathophysiology of brain cancers has been recently considered in light of its well-known involvement in carcinogenesis. Complement system represents an important component of the inflammatory response, which acts as a functional bridge between the innate and adaptive immune response. C1q, the first recognition subcomponent of the complement classical pathway, has recently been shown to be involved in a range of pathophysiological functions that are not dependent on complement activation. C1q is expressed in the microenvironment of various types of human tumors, including melanoma, prostate, mesothelioma, and ovarian cancers, where it can exer…
Prognostic significance of standardized AgNOR analysis and Ki-67 immunostaining in gastrointestinal stromal tumors
2003
Abstract OBJECTIVE: To evaluate the prognostic utility of argyrophilic nucleolar organizer region (AgNOR) protein parameters and Ki-67-immunostained growth fraction (Ki-67 labelling index) and to correlate AgNORs with Ki-67 LI and the main clinicopathologic parameters in gastrointestinal stromal tumors (GISTs). STUDY DESIGN: On 55 patients with surgically excised GISTs, visualization and quantification of AgNORs were performed as specified in the guidelines of the Committee on AgNOR Quantification. RESULTS: AgNOR protein area (NORA) ≥5.28 μm2 was statistically associated with mitotic rate ≥5x10 high-power fields (hpfs) (P <.001) and presence of necrosis (P <.001); Ki-67 LI ≥9.69% was signif…
Cukrzyca typu 2 i przewlekła choroba nerek jako czynniki rokownicze w ostrym zapaleniu trzustki
2019
Przeprowadzono analizę czynników rokowniczych ostrego zapalenia trzustki (OZT). Dokonano krytycznego przeglądu najważniejszych skali rokowniczych OZT: Apache II, Ransona, BISAP, Sofa, Marshalla. Wskazano na ich ograniczenia, ale i przydatność kliniczną we wczesnej stratyfikacji prognostycznej OZT. W diagnostyce różnicowej należy wyodrębniać etiologię alkoholową i żółciopochodną. Występująca przed zachorowaniem cukrzyca typu 2 i przewlekła choroba nerek znamiennie pogarszają przebieg OZT i powinny być włączone do skali rokowniczych. Wykazano, że obecność cukrzycy z poziomem HBA1C powyżej 6,5% wiąże się ze zwiększoną śmiertelnością wśród chorych na OZT i wydłuża się okres hospitalizacji o 5 d…
