对50例手术切除的胃癌标本进行观察,其中的20例有五年随访材料。结果如下:①29例(58％)为由一种组织类型的癌细胞组成,称为同质性胃癌;21例(42%)由二种或二种以上的组织学类型的癌细胞组成,称为异质性胃癌。②29例同质性胃癌中有20例淋巴结转移(68.97％),和21例异质性胃癌中有16例淋巴结转移(76.19%),X~2检测结果,两者的生物学行为无明显差异(P>0.05);③五年随访结果表明同质与异质性胃癌平均生存期分别为2.65年和1.94年,t检测结果,两者的预后未见明显差异(P>0.05)。作者估计若能收集更多的标本并结合电镜、免疫血化研究、最终会在两者的生物学特性及其预后后找到一定的规律。
50 cases of surgically resected gastric cancer specimens were observed, of which 20 cases had five-year follow-up materials. The results were as follows: 129 cases (58%) consisted of one tissue type of cancer cell, known as homogenous gastric cancer; 21 cases (42%) consisted of two or more histological types of cancer cells. For heterogeneous gastric cancer. There were 20 lymph node metastases (68.97%) in 229 homogenous gastric cancers and 16 lymph node metastases (76.19%) in 21 heterogenous gastric cancers. There was no significant difference in biological behavior between the two groups. (P>0.05); 3 Five-year follow-up results showed that the average survival time of homogenous and heterogeneous gastric cancer was 2.65 years and 1.94 years respectively. There was no significant difference in prognosis between the two groups (P>0.05). The authors estimate that if more specimens can be collected and combined with electron microscopy and immunoblotting, they will eventually find a certain pattern after the biological characteristics of the two and their prognosis.
