Relationship among COX-2 protein expression, PGs levels and biologic behavior in ovarian carcinoma tissues
      
Objective: To study the relationship among cyclooxygenase-2 (COX-2) protein expression, prostaglandins levels and biologic behavior in ovarian carcinoma tissues.
      
OBJECTIVE To explore the expression of the MDR1/P-glycoprotein, Fas and survivin and to examine their correlation with the biologic behavior of bladder transitional cell carcinoma (BTCC).
      
To date, more than 650 patients worldwide have been treated for gastric MALT lymphoma with antibiotics, and we have gained many new insights concerning the biologic behavior of this disease, especially from the deepened knowledge of cytogenetics.
      
The ability of imaging and cyst fluid analysis to predict the biologic behavior of the lesions has aroused much interest recently.
      
Biologic markers of angiogenesis are being evaluated for correlations with prognosis and biologic behavior of the tumor.
      
Pediatric soft-tissue sarcomas are increasingly being defined by both histologic appearance and underlying chromosomal abnormalities to determine their biologic behavior.
      
This review analyzes the fusion gene expressions seen with seven of the major types of pediatric soft-tissue tumors and their impact on biologic behavior.
      
Several of these variants are sufficiently rare that their biologic behavior remains obscure.
      
By contrast, hTERT was clearly associated with aggressive biologic behavior.
      
Endogenous proteases, including cathepsin B (CB) and cathepsin D (CD), have been linked to tumor progression in other malignancies and may be important in the different biologic behavior of these follicular thyroidal lesions.
      
p27 and other cell-cycle proteins are becoming increasingly important in assessing the biologic behavior of endocrine neoplasms, classifying hyperplastic and neoplastic endocrine tissues, and in the progression of endocrine tumors.
      
Its morphologic features and biologic behavior differ from those of larger medullary carcinomas.
      
Histopathologic evaluation using a multivariate scoring system is considered most effective in discerning malignancy and biologic behavior of resected adrenocortical neoplasms.
      
Goblet cell carcinoid (GCC) of the appendix is a rare entity, of which both the histogenesis and biologic behavior remain controversial, and prognostic tools and therapeutic strategies for this unusual tumor have yet to be defined.
      
The aim of the present study was to evaluate the expression pattern of CAMs in adrenal tumors regarding origin (cortex vs medulla) and biologic behavior (benign vs malignant).
      
Review of the literature substantiates the argument that clinically evident PTC may be distinctly different from solitary or multifocal PMC in terms of etiology and biologic behavior, supporting a conservative approach to management.
      
PET's resemble carcinoid tumors histologically; in their ability to synthesize and frequently secrete multiple peptides such as neuroendocrine cell markers (chromogranins); their biologic behavior and their tumor growth patterns.
      
It resembles malignant melanoma in its cutaneous presentation, unpredictable biologic behavior, early regional lymph node involvement, early distant metastases, and high recurrence rate.
      
These systems are based on a few morphologic predictors of biologic behavior, which is justifiable because of the rarity of soft tissue sarcomas.
