Gastric carcinoma occurs in response to chronic inflammation of gastric mucosa infected with Helicobacter pylori. It is not known how cytokines affect the growth and progression of gastric carcinoma.
We measured tissue concentrations of the proinflammatory cytokines interleukin (IL)-1beta and IL-6 in gastric carcinoma and investigated the correlation between the levels of these cytokines and clinicopathological features. Biopsy specimens of tumors or adjacent normal mucosa were obtained from 42 Japanese patients with gastric carcinoma. Tissue levels of IL-1beta and IL-6 were measured by enzyme-linked immunosorbent assay.
IL-1beta levels were significantly higher in the neoplasm than in the corresponding normal mucosa. The IL-6 levels in the neoplasm correlated significantly with the depth of invasion and lymphatic invasion. High levels of IL-1beta and IL-6 were characteristic of non-scirrhous type gastric carcinoma.
These results suggest that IL-1beta and IL-6 are involved in the growth and progression of human gastric carcinoma.
胃癌是由感染幽门螺杆菌的胃黏膜慢性炎症引起的。目前尚不清楚细胞因子如何影响胃癌的生长和进展。
我们测量了胃癌组织中促炎细胞因子白细胞介素(IL)-1β和IL-6的浓度,并研究了这些细胞因子水平与临床病理特征之间的相关性。从42例日本胃癌患者中获取肿瘤或相邻正常黏膜的活检标本。通过酶联免疫吸附测定法测量IL-1β和IL-6的组织水平。
肿瘤组织中IL-1β水平显著高于相应的正常黏膜。肿瘤组织中的IL-6水平与浸润深度和淋巴浸润显著相关。高水平的IL-1β和IL-6是非硬化型胃癌的特征。
这些结果表明IL-1β和IL-6参与了人类胃癌的生长和进展。
