Background Fine needle aspiration cytology (FNAC) is a quick method to assess the tumor grade before its removal which will help clinicians to decide on the appropriate neo adjuvant therapy. This is essentially true in developing countries where core needle biopsy still is not used as a standard practice to sample breast carcinoma. Assessment of biological aggressiveness by cytological grading ...

Background: Fine needle aspiration cytology is an important tool in the diagnosis, prognosis and management of breast carcinoma. It has been recommended that cytological grading should be included in the FNA reports to know the tumor aggressiveness and prognostication. Among the many cytological grading systems existing, there is still no agreement on the most reliable system. Aim: The study wa...

We present the results on the development of an automated system for prostate cancer diagnosis and Gleason grading. Images of representative areas of the original Hematoxylin-and-Eosin (H&E)-stained tissue retrieved from each patient, either from a tissue microarray (TMA) core or whole section, were captured and analyzed. The image sets consisted of 367 and 268 color images for the diagnosis an...

The molecular characterization of endometrial endometrioid adenocarcinomas has provided major advances in its prognostic stratification. However, risk assessment microsatellite instability (MSI) and copy-number (CN)-low cases remains a challenge. Thus, we aimed to identify tissue-based morphologic biomarkers that might help the stratification these cases. Histomorphologic parameters (WHO gradin...

Medulloepithelioma is a rare congenital tumor of the ciliary body and iris. The current classification and grading of medulloepithelioma shows inconsistencies and does not reflect clinical behavior. This position paper discusses the backgrounds of the current classification and intends to initiate a discussion on an alternative classification and grading scheme.

INTRODUCTION The aim of the present study was to evaluate the influence of clinicopathological factors including age, gender, tumor grade, tumor stage, lymphovascular invasion (LVI), tumor necrosis and previous history of non-muscle invasive bladder cancer on outcomes of patients with upper tract urothelial carcinoma (UTUC) treated with radical nephroureterectomy (RNU). MATERIAL AND METHODS A...

INTRODUCTION The most common primary tumors of brain are gliomas and tumor grading is essential for designing proper treatment strategies. The gold standard choice to determine grade of glial tumor is biopsy which is an invasive method. The purpose of this study was to investigate the role of fiber density index (FDi) by means of diffusion tensor imaging (DTI) (as a noninvasive method) in glial...

A glioma is a type of intra-axial brain tumor originating from the glial cells. Making up about one-third all tumors, timely diagnosis alongside correct grading and subsequent therapy planning crucial. Magnetic Resonance Imaging an established method for tumors. Arterial Spin Labeling (ASL) Perfusion allows non-contrast enhanced visualization hyper- or hypoperfusion. Commonly, cell swelling occ...
