356例腺癌神经内分泌标志物的研究

目的：观察神经内分泌（NE）细胞及其激素产物在普通型腺癌中的发现率，探讨其临床病理学意义。方法：应用铬粒素及多肽类激素抗体免疫细胞化学方法对356例腺癌进行研究。结果：NE细胞发现率及其激素产物阳性率分别为大肠癌41．5％（54／130）与59．3％（32／54）、胃癌39．6％（38／96）与36．8％（14／38）、前列腺癌38．1％（8／21）与50．0％（4／8）、乳腺癌21．0％（17／81）与17．6％（3／17）及胰腺癌17．9％（5／28）与60．0％（3／5）。在大肠癌、胰腺癌及乳腺癌中，高分化癌NE细胞的发现率明显高于低分化癌，而胃癌则相反，NE细胞在低分化癌中明显多于高分化癌。大肠癌，与NE细胞阴性者比较，NE（＋＋）或多肽激素阳性的肿瘤患者的5年存活率较高。结论：神经内分泌细胞及其激素产物与肿瘤分化有一定的关系；大肠癌的分析结果表明，NE细胞及其激素产物与肿瘤临床病理分期及预后相关。

Study of neuroendocrine markers in 356 cases of adenocarcinomas

Objective: To ivestigate the incidence of neuroendocrine (NE) cells and hormone products in adenocarcinomas and to explore its clinicopathological significance. Methods: 356 cases of adenocarcinomas were studied by immunocytochemistry with antibodies for chromorgranin and polypeptide hormones. Results: The prevalence of NE cells and hormone products were detected in 54 of 130(41.5%) and 32 of 54 (59.3%) colorectal carcinomas, 38 of 96(39.6%) and 14 of 38 (36.8%) gastric cancer, 8 of 21(38.1%) and 4 of 8(50.0%) prostatic carcinomas, 17 of 81(21.0%) and 3 of 17(17.6%) breast cancer, 5 of 28(17.9%) and 3 of 5 (60.0%) pancreatic carcinomas, respectively. Among carcinomas of large intestine, pancreas and breast, the incidence of NE cells in well differentiated ones was higher than that in the poorly differentiation. By contrast, NE cells were found more frequently in the letter than in the former in gastric carcinoma. The cases with NE cell (++) or polypeptide positive cells exhibited higher 5 year survival rate than those without NE cells in colorectal carcinomas. Conclusion: The presence of neuroendocrine cells and the hormone products may be close correlated with the degree of tumore cell differen tiation. For colorectal carcinoms, there is a close correlation of the presence of NE cells and the hormone products with the tumor staging and prognosis.
