摘　　要：目的:探究甲状腺癌(TC)组织中磷脂酶Cδ3(PLCD3)和细胞周期蛋白D1(CCND1)的表达及其临床意义。方法:选择在本院2019年2月至2021年2月收治的126例TC患者为研究对象,收集患者术中切除的癌组织及其癌旁组织为组织样本。运用免疫组织化学法及实时荧光定量PCR检测TC组织中PLCD3、CCND1表达水平;分析TC组织中PLCD3、CCND1表达水平与临床病理特征及TC患者预后的相关性;采用多因素Cox回归分析影响TC患者预后的因素。结果:TC组织中PLCD3、CCND1的阳性表达率显著高于癌旁组织(P<0.05),PLCD3、CCND1 mRNA表达水平也明显高于癌旁组织(P<0.05)。临床分期为Ⅲ~Ⅳ期、有淋巴结转移及分化程度为低分化的TC患者PLCD3、CCND1阳性表达比例明显高于Ⅰ~Ⅱ期、无淋巴结转移及中高分化的TC患者(P<0.05)。PLCD3阳性表达患者3年生存率(40/93,43.01%)低于PLCD3阴性表达患者(25/33,75.76%)(χ^(2)=12.889,P<0.001);CCND1阳性表达患者3年生存率(41/96,42.71%)也低于CCND1阴性表达患者(24/30,80.00%)(χ^(2)=13.939,P<0.001)。PLCD3、CCND1、临床分期、淋巴结转移是TC患者预后的影响因素(P<0.05)。结论:TC组织PLCD3、CCND1阳性表达率显著升高,其与TC患者临床分期、淋巴结转移密切相关,对预测患者预后有一定参考价值。Objective:To investigate the expression and clinical significance of phospholipase C-delta-3(PLCD3)and cyclin D1(CCND1)in thyroid cancer(TC)tissue.Methods:A total of 126 TC patients who were treated in our hospital from February 2019 to February 2021 were regarded as the study subjects,and the excised cancer tissue and its adjacent tissues during surgery were used as the controltissue samples.Immunohistochemical methods and real-time fluorescence quantitative PCR were applied to detect the expression levels of PLCD3 and CCND1 in TC tissues.The correlation between the expression levels of PLCD3 and CCND1 in TC tissue with clinical pathological characteristics and the prognosis of TC patients was analyzed.The factors affecting the prognosis of TC patients were analyzed using multivariate Cox regression.Results:The positive expression rates of PLCD3 and CCND1 in TC tissues were greatly higher than those in adjacent tissues(P<0.05).The expression levels of PLCD3 and CCND1 mRNA in TC tissues were significantly higher than those in paracancer tissues(P<0.05).The positive expression rates of PLCD3 and CCND1 in TC patients with clinical stagesⅢ-Ⅳ,lymph node metastasis,and low differentiation were greatly higher than those in TC patients with clinical stagesⅠ-Ⅱ,medium to high differentiation,and no lymph node metastasis(P<0.05).The 3-year survival rate of PLCD3 positive expression patients(40/93,43.01%)was lower than that of PLCD3 negative expression patients(25/33,75.76%)(χ^(2)=12.889,P<0.001).The 3-year survival rate of CCND1 positive expression patients(41/96,42.71%)was lower than that of CCND1 negative expression patients(24/30,80.00%)(χ^(2)=13.939,P<0.001).PLCD3,CCND1,clinical stage,and lymph node metastasis were prognostic factors for TC patients(P<0.05).Conclusion:The positive expression rates of PLCD3 and CCND1 in TC tissue are greatly increased,which is closely related to clinical staging and lymph node metastasis in TC patients,and has certain reference value for predicting prognosis.
