放射免疫测定生长抑素（SS）在20例肠癌、20例癌周、12例息肉、10例正常对照标本中的含量。SS在癌组织、癌周组织、息肉中过量表达，均明显高于正常对照组（P＜0．01），而且SS在上述四种组织中依次递减，差异显著（P＜0．01）。SS在癌组织中表达与肿瘤病理分型以及结肠癌周围淋巴结转移无明显相关（P＞0.05）。本文表明，结肠癌患者肿瘤组织内SS有特异性积累，并且可能在肠癌发生中起一定作用，从而有可能为结肠癌的发生提供新的探索途径。
Radioimmunoassay was used to determine the content of somatostatin (SS) in 20 cases of colorectal cancer, 20 cases of cancer, 12 cases of polyps, and 10 normal controls. SS was overexpressed in cancer tissues, pericancerous tissues, and polyps, which were significantly higher than those in the normal control group (P<0.01). Moreover, SS was gradually decreased in the above four tissues, and the difference was significant (P<0.01). There was no significant correlation between the expression of SS in cancer tissues and pathological type of tumors and lymph node metastasis of colon cancer (P>0.05). This article shows that there is a specific accumulation of SS in the tumor tissue of colon cancer patients, and may play a role in the occurrence of colon cancer, which may provide new exploration ways for the occurrence of colon cancer.
