摘要:

目的 探讨核心蛋白聚糖(Decorin)和骨甘氨酸(Mimecan)在宫颈癌中的表达及二者与患者临床病理特征和预后的关系。方法 选取148例接受手术治疗的宫颈癌患者,应用免疫组织化学法检测Decorin和Mimecan蛋白表达情况,比较不同临床病理特征患者Decorin和Mimecan阳性表达率,分析二者相关性,Cox回归模型分析宫颈癌患者死亡的危险因素,Kaplan-Meier生存曲线比较Decorin和Mimecan阳性和阴性患者的生存率。结果 Decorin和Mimecan蛋白在宫颈癌组织中的阳性表达率均低于癌旁组织(20.0% vs. 75.0%,28.3% vs. 63.3%,均P<0.05)。肿瘤直径≥2 cm、FIGO分期Ⅲ—Ⅳ期、有淋巴结转移和肿瘤低分化程度患者的Decorin和Mimecan表达阳性率均较低(P<0.05)。宫颈癌组织中Decorin和Mimecan表达呈正相关(r=0.686,P<0.01)。多因素Cox回归证实,Decorin(HR=2.365,95%CI:1.236~4.525)和Mimecan阴性表达(HR=2.191,95%CI:1.322~3.631)、FIGO分期Ⅲ—Ⅳ期(HR=1.747,95%CI:1.147~2.660)和肿瘤低分化(HR=1.577,95%CI:1.035~2.404)为宫颈癌患者死亡的独立危险因素(P<0.05)。Decorin和Mimecan阳性表达患者的5年生存率高于阴性表达者(79.3% vs. 51.3%,73.8% vs. 50.0%),中位生存时间延长(75个月 vs. 60个月,74个月 vs. 60个月)。结论 Decorin和Mimecan在宫颈癌组织中的阳性表达率降低,可作为宫颈癌预后评估的潜在生物标志物。

Abstract:

Objective To explore the expression of core proteoglycans (Decorin) and osteoglycine (Mimecan) in cervical cancer and their relationship with the characteristics of clinical pathological traits and the prognosis of patients. Methods A total of 148 patients with cervical cancer who underwent surgical treatment in our hospital were selected. The expression levels of Decorin and Mimecan were determined by immunohistochemistry (IHC). The positive expression rates of Decorin and Mimecan in patients with different clinicopathological features were compared, and the correlation between the two was analyzed. Cox regression model was used to assess risk factors for death in patients with cervical cancer. Kaplan-Meier survival curve was used to compare the survival rates of patients with positive and negative Decorin and Mimecan expression. Results The positive expression levels of Decorin and Mimecan were both lower in cervical cancer tissue than those in adjacent tissue of cancer (20.0% vs. 75.0%, 28.3% vs. 63.3%, all P<0.05). The positive expression rates of Decorin and Mimecan were lower in patients with a tumor diameter ≥ 2 cm, FIGO stage Ⅲ-Ⅳ, lymph node metastasis and low tumor differentiation degree compared to those with a tumor diameter<2 cm, FIGO stage Ⅰ-Ⅱ, no lymph node metastasis and moderately to well tumor differentiation degree (P<0.05). There was a positive correlation of Decorin and Mimecan in cervical cancer tissue (r = 0.686, P<0.01). Multivariate Cox regression analysis confirmed that negative expression of Decorin (HR = 2.365, 95%CI: 1.236-4.525) and Mimecan (HR = 2.191, 95%CI: 1.322-3.631), FIGO stage Ⅲ-Ⅳ (HR = 1.747, 95%CI: 1.147-2.660) and low tumor differentiation degree (HR = 1.577, 95%CI: 1.035-2.404) were independent risk factors for mortality in cervical cancer patients (P<0.05). The 5-year survival rate of patients with positive Decorin and Mimecan expression was higher than those with negative expression (79.3% vs. 51.3%,73.8% vs. 50.0%), and the median survival time was prolonged (75 months vs. 60 months, 74 months vs. 60 months). Conclusion The positive expression rates of Decorin and Mimecan are reduced in cervical cancer tissue and may serve as potential biomarkers for prognostic evaluation of cervical cancer.
