生物学行为是影响胃癌预后的重要因素而核面积是影响因素中最重要一个。本文按生长方式对胃癌作了新的病理生物学分型的尝试,把胃癌分作膨胀型和浸润型,每型又依核面积大小分为大核型和小核型。结果表明,本文的分型较其他分型更能体现肿瘤的生物学特性,值得提倡。 Biological behavior is an important factor affecting the prognosis of gastric cancer. Nuclear area is the most important one of the factors. In this article, we try to make a new pathobiological classification of gastric cancer according to the growth pattern. The gastric cancer is divided into inflated and infiltrated type. Each type is divided into large karyotype and small karyotype according to the size of the nuclear area. The results show that the classification of this article is more able to reflect the biological characteristics of the tumor than other classifications and is worthy of promotion.
