[Relationship and role of morphological diagnosis and gene diagnosis of cancer (1) tumors in the gastrointestinal tract].
At present histopathological examination based on clinical findings is the most important and definitive method of diagnosing gastrointestinal tumors. In this field, gene analysis is sometimes used as a supplemental diagnosis. However, fruitful analyses of gene abnormalities in gastrointestinal tumors have facilitated thoughtful morphological diagnosis. Gene diagnosis is expected to play an important role in the grading of malignancy, examining sensitivity for chemotherapy and discovering micrometastases, in cases of cancers definitively diagnosed by histopathology.
