摘要: 摘要: 目的 探讨结肠癌转移相关基因 1 (MACC1) 及肝细胞生长因子受体 (c-Met) 在前列腺癌中的表达及其与前列腺癌发展、 浸润和转移的关系。方法 采用枸椽酸-微波-SP 免疫组织化学染色法检测 67 例前列腺癌组织及 30 例前列腺增生 (BPH) 组织中 MACC1 和 c-Met 的表达情况, 并结合临床病理因素进行相关分析。结果 MACC1 及 c-Met 表达水平在前列腺癌组织中不同 Gleason 分级、 病理分级、 前列腺特异性抗原 (PSA) 水平及根治术后是否发生骨转移方面差异有统计学意义 (P<0.05 或 P < 0.01), 而不同年龄, 是否吸烟的表达水平差异无统计学意义; 且Ⅲ期和Ⅳ期前列腺癌中 MACCl 的高表达率明显高于 BPH (P < 0.05), c-Met 蛋白高表达率仅在Ⅳ期前列腺癌高于 BPH (P < 0.05)。前列腺癌中 MACC1 与 c-Met 的表达呈正相关 (P<0.01)。Kaplan-Meier 生存曲线表明前列腺癌组织中 MACC1 及 c-Met 高表达较低表达无骨转移生存时间短且生存率低。结论 MACC1 和 c-Met 的异常高表达可能与前列腺癌的发展及浸润密切相关, 且预示骨转移的发生, 可能成为多种恶性肿瘤判断预后、 诱导转移的预测指标。

Abstract: Abstract: Objective This study is to investigate the expressions of MACC1 and c-Met genes in prostate cancer tis⁃ sues and to explore the relationship between these gene expressions with the development, invasion and metastasis of pros⁃ tate cancer. Methods The expressions of MACC1 and c-Met genes were examined in 30 cases of benign prostatic hyperpla⁃ sia and 67 cases of prostate cancer using citron acid-microwave-SP immunohistochemical method and analysed with their clinical pathological features. Results Expressions of MACC1 and c-Met in prostate tissues show statistical difference ac⁃ cording to Gleason score, PSA level, pathological stages and whether bone metastasis occurs after radical surgery (P < 0.05 or P < 0.01), but their expressions in prostate tissue show no significant difference among different sex, age and whether smoking or not. Expression of MACC1 in prostate tissue of stage Ⅲ and Ⅳcancer is significantly higher than that in benign prostatic hyperplasia (BPH) tissues (P < 0.05) while the expression of c-Met only shows statistical difference in prostate tis⁃ sue of stage Ⅳcancer compared with that in BPH (P < 0.05). There is a positive correlation between the expression of MACC1 with expression of c-Met in prostate cancer tissues (P < 0.01). Kaplan-Meier curves revealed that the survival rates was lower and survival time of bone-free metastasis were shorter in patients with high MACC1 and c-Met expressions in prostate tissue than those with low expressions of MACC1 and c-Met in prostate tissue. Conclusion Expression of MACC1 and c-Met is closely related to the development, invasion and metastasis of prostate cancer, so MACC1 and c-Met may be used as promising diagnostic and prognostic markers for prostate tumor, and as new therapeutic targets for prostate cancer.
