Histologic grade is an important determinant in clinical outcome of human osteosarcoma (OS). In this study, the histologic characteristics of primary and metastatic canine OS were evaluated using a new classification system. Histologic characteristics were classified in 166 primary and 34 metastatic canine OS. Prognostic variables for clinical outcome were determined using multivariate analysis...
BACKGROUND Neither clinical prediction models nor noninvasive imaging tests that detect coronary artery calcification identify all patients who experience acute coronary events. Variations in culprit plaque morphology may account for these inaccuracies. METHODS AND RESULTS We compared the 10-year Framingham risk index, histologic coronary calcification, and culprit plaque morphology in 79 con...
Age has been used as a prognostic factor for patients with peripheral neuroblastic tumours (pNTs). The latest analysis disclosed a cut-off around 18 months for the optimal prognostic distinction. The International Neuroblastoma Pathology Classification (INPC) distinguishes favourable and unfavourable histology based on the age-appropriate evaluation of histologic indicators (grade of neuroblast...
OBJECTIVES The histologic and immunohistochemical variability of renal epithelial tumors makes classification difficult; with significant clinical implications, efforts to make the proper diagnoses are necessary. Single-nucleotide polymorphism (SNP) microarray analysis has been proposed as a supplementary study for the classification of renal epithelial neoplasms; however, its practical use in ...
CONTEXT Histologic examination of thyroid nodules is the current standard to distinguish benign from malignant thyroid epithelial tumors and to classify histologic subtypes. This review analyzes the problems in histological differential diagnosis as well as contradictions between histology and molecular data and describes possibilities to combine histology with molecular data in an effort to mo...
The term “high-grade non-Hodgkin’s lymphomas” refers to three histologic subtypes categorized in the Working Formulation1 classification (Table 10–1). At that time, the definitions of low-, intermediate-, and high-grade lymphomas were based on differences in survival, and those with the worst prognoses were considered the high-grade histologic subtypes of small noncleaved cell lymphoma (SNCCL),...
BACKGROUND & AIMS There is no histologic classification system to determine prognoses of patients with alcoholic hepatitis (AH). We identified histologic features associated with disease severity and created a histologic scoring system to predict short-term (90-day) mortality. METHODS We analyzed data from 121 patients admitted to the Liver Unit (Hospital Clinic, Barcelona, Spain) from Januar...
