摘要:
目的 分析探讨早期宫颈癌淋巴结转移的高危因素,研究HIST1H3D对早期宫颈癌淋巴结转移的预测价值。 方法 从蚌埠医学院第一附属医院选取2021年1—12月在妇产科行根治性子宫切除术的早期宫颈鳞癌患者组织40例,以及2016年1月—2020年12月的早期宫颈鳞癌患者蜡块标本124例。通过RT-qPCR、Western blotting和免疫组化分析HIST1H3D在淋巴结转移组与非转移组的表达差异;通过χ2检验及生存分析曲线分析HIST1H3D对早期宫颈癌淋巴结转移组与非转移组临床特征和生存的影响;使用二元logistic回归分析淋巴结转移的影响因素。 结果 FIGO分期(χ2=30.491,P<0.001),肿瘤大小(χ2=8.362,P<0.004),淋巴血管间隙浸润(χ2=29.350,P<0.001)和HIST1H3D表达(χ2=4.148,P<0.042)等与淋巴结转移显著相关。HIST1H3D基因过表达是早期宫颈癌淋巴结转移的高危因素,淋巴结阳性组患者生存率更差(P=0.014)。HIST1H3D的高低表达组生存率存在显著差异,HIST1H3D低表达组生存期更长(P=0.019)。ROC曲线结果表明当HIST1H3D免疫组化评分为5时,曲线下面积(AUC)为0.704,灵敏度为89.29%,特异度为64.71%,此时对淋巴结转移预测效果最佳(P<0.001)。 结论 HIST1H3D对早期宫颈癌淋巴结转移有预测价值。 -

Abstract:Objective To analyze the high-risk factors of lymph node metastasis in early cervical cancer, and study the predictive value of HIST1H3D in lymph node metastasis of cervical cancer. Methods A total of 40 patients with early cervical squamous cell carcinoma who underwent radical hysterectomy in Department of Obstetrics and Gynecology from January to December 2021 and 124 patients with early cervical squamous cell carcinoma from January 2016 to December 2020 were selected from the First Affiliated Hospital of Bengbu Medical College. The expression difference of HIST1H3D in lymph node metastasis group and non-metastasis group was analyzed by RT-qPCR, Western Blot and immunohistochemistry. Chi-square test and survival curve analysis were used to analyze the influence of HIST1H3D on the clinical characteristics and survival of lymph node metastasis group and non-metastasis group of early stage cervical carcinoma. The influencing factors of lymph node metastasis were analyzed by binary logistic regression. Results FIGO stage (χ2=30.491, P < 0.001), tumor size (χ2=8.362, P < 0.004), infiltration of lymphatic vascular space (P < 0.001), vaginal involvement (χ2=29.350, P < 0.001) and HIST1H3D expression (χ2=4.148, P < 0.042) were significantly related to lymph node metastasis. Overexpression of HIST1H3D gene was a high-risk factor for lymph node metastasis in early cervical cancer. The survival rate of patients with positive lymph nodes was worse (P=0.0136). There was significant difference in survival rate between the high and low expression groups of HIST1H3D, and the low expression group of HIST1H3D had a longer survival time (P=0.019). ROC curve showed that when HIST1H3D immunohistochemical score was 5, the area under the curve (AUC) was 0.704, the sensitivity was 89.29%, the specificity was 64.71%. At this time, the prediction effect of lymph node metastasis was the best (P < 0.001). Conclusion HIST1H3D has predictive value for lymph node metastasis of early stage cervical cancer. -
