In the United States, it causes more cancer-related deaths than the next four causes （breast cancer, prostate cancer, colon cancer, and pancreatic cancer） of cancer-related mortality combined （1）. About 30% of people have already progressed to stage III lung cancer and 40% to stage IV at the time they are diagnosed （2）. Although chest X-ray and sputum cytology, when applied in health check-ups, can identify some relatively small tumors, they are not able to lower the overall mortality （3）. More recently,展开更多

The purpose of this study was to determine the number of the lymph nodes in the CLND and the relationship to presence of chronic lymphocytic thyroiditis (CLT) and thymic tissue (TT). Methods: Total thyroidectomy and CLND materials from 153 patients with PTC were included in this study. Two histopathologic features (presence of CLT and TT) were evaluated for their value in adequacy of CLND. Results: Histopathologic examination revealed CLT and TT in CLND materials in 70 (46%) and 63 (41%) patients, respectively. Total number of lymph nodes in CLND materials was significantly higher in CLT (+) and TT (+) groups (p Conclusions: Our study demonstrates that presence of CLT in thyroid gland has been associated with higher number of central lymph nodes mainly due to increased number of benign hyperplastic lymph nodes. It may be possible to conclude that upper limit of lymph nodes for satisfactory CLND would be higher to correctly evaluate central lymph node status in existing staging systems if specimens have CLT. Results of this study also show that the presence of TT in surgical materials may represent the adequacy of CLND.展开更多

文摘目的:本研究旨在建立甲状腺乳头状癌(Papillary Thyroid Carcinoma,PTC)患者大量中央区淋巴结转移[(high-volume Central Lymph Node Metastasis,hv-CLNM)中央区淋巴结转移数量>5]的预测模型。方法:纳入2021年1月—2024年6月于石河子大学第一附属医院行手术的579例PTC患者。数据按照7∶3比例随机分为训练集(n=406例)和验证集(n=173例),根据训练集术后CLNM数量分为hv-CLNM组(n=23例)和非hv-CLNM组(n=383例)。采用独立样本t检验、曼-惠特尼检验和卡方检验等比较组间差异。运用单变量和多变量逻辑回归分析筛选独立危险因素并绘制列线图,利用ROC曲线下面积(Area Under Curve,AUC)、校准曲线和决策曲线评估列线图模型效能。结果:差异分析显示,2组间年龄、性别、肿瘤大小、病灶数目、微钙化和TSH水平差异有统计学意义(P<0.05)。单变量和多变量逻辑回归显示,男性、年龄小于55岁、肿瘤大小≥7 mm、多灶性肿瘤、伴有微钙化以及TSH水平较高是hv-CLNM的预测因子(P<0.05)。根据多因素结果构建的列线图模型具有较高的诊断效能,其训练集AUC:0.894(95%CI:0.817~0.970),验证集AUC:0.801(95%CI:0.578~1.000)。校准曲线和决策曲线验证模型较好的一致性和临床效用。结论:基于本中心数据构建的TSH联合超声特征模型对PTC患者hv-CLNM有较高的预测价值,未来还需要进一步验证和优化。
