introduction: c - reactive protein (crp) is an acute-phase plasma protein that can be used as a marker of activation of the immune system. in response to several inflammatory reactions,the concentration of crp increases and recently have been applicated as a cancer detector in some studies. we aimed to evaluate the relation between crp level and the staging and grading of gastric and colon mali...

Grading of renal cell carcinoma (RCC) has prognostic significance, and there is recent consensus by the International Society of Urological Pathology (ISUP) that for clear cell and papillary RCC, grading should primarily be based on nucleolar prominence. Microscopic tumor necrosis also predicts outcome independent of tumor grading. This study was undertaken to assess whether the incorporation o...

BACKGROUND Several grading schemes for the extent of residual tumor in posttreatment pancreaticoduodenectomy (PD) specimens have been proposed. However, the prognostic significance of these grading schemes is unknown. METHODS Histopathologic slides of 223 cases who received neoadjuvant chemoradiation and PD were reviewed. The extent of residual tumor was graded using both the College of Ameri...

The conventional histologic grading of colorectal cancer (CRC) is less suited for resected rectal cancer following neoadjuvant chemoradiation. Enumeration of poorly differentiated clusters (PDC) is a recently proposed histologic grading scheme. We aimed to apply PDC grading to treated rectal cancer and to test the prognostic significance of this novel approach. Archived hematoxylin and eosin sl...

OBJECTIVE To examine correlations among nuclear, architectural, and International Federation of Gynecology and Obstetrics (FIGO) grading systems, and their relationships with lymph node (LN) involvement in endometrioid endometrial cancer. MATERIAL AND METHODS Histopathology slides of 135 consecutive patients were reviewed with respect to tumor grade and LN metastasis. Notable nuclear atypia w...

Poor histological differentiation is currently considered among the adverse histopathological factors associated with unfavourable clinical course of colorectal carcinoma (CRC). At present, the histological grade of CRC is assessed based on the percentage of glandular differentiation in the tumor according to the World Health Organization (WHO) criteria. However the prognostic value of the WHO ...

BACKGROUND Susceptibility weighted imaging (SWI) is a velocity compensated, high-resolution three-dimensional (3D) spoiled gradient-echo sequence that uses magnitude and filtered-phase data. SWI seems to be a valuable tool for non-invasive evaluation of central nervous system gliomas. Relative cerebral blood volume (rCBV) ratio is one of the best noninvasive methods for glioma grading. Degree o...

AIM The value of grading tumor regression after neoadjuvant therapy of rectal carcinoma was evaluated. PATIENTS AND METHODS Analysis was carried out using prospective data of 225 patients with rectal carcinoma treated by neoadjuvant radiochemotherapy followed by radical resection with curative intent. For the histological regression grading, the method of Dworak et al. (1997) was used with a ...
