title: Comparative study of clinical-morphological profiles of different types of gastric carcinoma.
abstract: OBJECTIVE
  Gastric carcinoma shows considerable variation in the histological pattern and degree of differentiation. The aim of the study was to assess especially the morphological differences between gastric carcinomas revealing one morphological feature and those including two morphological features.
  
  
  METHODS
  Two groups of patients were selected: Group 1, including 43 patients with tumors revealing only one architectural pattern, and Group 2, including 16 patients with two architectural patterns within the tumor. In addition to gender and age, the main morphological parameters were: lesion location and macroscopic appearance on the surgical excision sample and microscopic appearance of the surgical excision sample, assessed for architectural pattern, secretory properties and prognosis based on histological features, degree of tumor extension and the degree of tumor aggressiveness, using a wide range of histological and immunohistochemical stainings. All data were compared between the two groups using statistical tests.
  
  
  CONCLUSIONS
  Significant differences were observed between the values and distributions of morphological parameters in the two groups and were discussed comparatively.
  
  
  CONCLUSIONS
  Tumors with two dominant histological aspects present simultaneously are a reality that cannot be argued but whose morphological and biological profile needs to be completed and validated.
