摘要
目的:探讨富含亮氨酸蛋白LRP130抗体(LRPPRC)在胃癌、宫颈癌和前列腺癌的表达和临床意义。方法:应用免疫组化法检测120例胃癌、80例宫颈癌和198例前列腺癌组织中LRPPRC的表达;分析LRPPRC的表达和临床病理学参数的关系。结果:胃癌和正常胃组织LRPPRC的高表达率分别为71.7%(86/120)和21.7%(13/60),二者差异有统计学意义(P<0.001);宫颈癌和正常宫颈组织LRPPRC的高表达率分别为76.3%(61/80)和27.5%(11/40),二者差异有统计学意义(P<0.001);前列腺癌和前列腺增生组织LRPPRC的高表达率分别为61.6%(122/198)和18.0%(18/100),二者差异有统计学意义(P<0.001)。LRPPRC的高表达与前列腺癌患者的Gleason评分、血清PSA水平、雄激素阻断治疗后PSA下降水平和转移部位的数量相比呈显著正相关(P<0.05)。结论:恶性肿瘤组织LRPPRC表达增高;晚期前列腺癌LRPPRC的高表达预示恶性程度高和多发转移。
Objective: To investigate the expressions and clinical significance of LRPPRC in cancer. Methods: Immunohistochemistry was performed to analyze the LRPPRC expression in 120 of gatric cancer tissues? 80 of cervi-cal cancer tissues and 198 of prostate cancer tissues. The associations between LRPPRC and clinicopathological pa-rameters were analyzed. Results : Gastric cancer and normal gastric tissues highly expressed LRPPRC in 71. 7% (86/120) and 21. 7% (13/60) of patients, respectively (P〈0 .001 ) ; Cervical cancer and normal cervical tissues highly expressed LRPPRC in 76. 3% (61/80)and 27. 5% (11/40) of patients, respectively (P〈0 .001) ; Prostate cancer and prostate hyperplasia tissues highly expressed LRPPRC in 61. 6% (122/198) and 18. 0% (18/100) of pa-tients ,respectively (P〈0. 001). A significant associations between the expressions of LRPPRC and Gleason scores (P〈0. 001),serum PSA levels (P = 0. 002) , serum PSA levels after androgen deprivation therapy (P〈0. 022)and the numbers of metastasis position (P〈0. 001) were observed. Conclusion: There is higher LRPPRC expression in cancer tissues. The high expression of LRPPRC predicted high degree of malignant and more metastasis positions in late stage of prostate cancer patients.
