[High risk groups for gastrointestinal carcinoma].
High-risk groups for gastrointestinal carcinoma are heterogenic in regard to etiopathology; familial predisposition and genetic defects (familial adenomatosis coli, tylosis palmaris et plantaris, Gardner syndrome, Peutz-Jeghers syndrome), occupational factors (asbestor exposure), surgical intervention (resected stomach, ureterosigmoidostomy), long lasting passage obstruction (oesophagus) or chronic inflammatory alteration of the mucosa (pernicious anemia, ulcerative colitis, Crohn's disease, glutenenteropathy). Although high-risk groups account only for about 5 per cent of all carcinomas, consequent follow-up examinations of these small collectives offer early diagnosis of carcinoma at a curable stage.
