Studies on the relationship between V600E mutation and the clinicopathologic features of papillary thyroid carcinoma (PTC), risk of lymph node metastasis in papillary thyroid microcarcinoma (PTMC) have shown inconsistent results.
In this retrospective analysis, clinicopathological data of the patients were collected, and molecular testing was done for V600E mutation. PTC patients are divided into PTC≤1.0cm (PTMC) and PTC>1.0cm, and the relationship between V600E mutation and clinicopathologic features was analyzed respectively.
Of the 520 PTC patients, 432 (83.1%) were female and 416 (80.0%) were <55 years old. V600E mutation was detected in 422 (81.2%) tumour samples of PTC. There was no significant difference in the frequency of V600E mutation between different age groups. There were 250 (48.1%) patients with PTMC and 270 (51.9%) patients with PTC>1.0cm. V600E mutation was significantly associated with bilateral cancer (23.0% vs 4.9%, =0.005) and lymph node metastasis (61.7% vs 39.0%, =0.009) in PTMC patients, while V600E mutation was significantly associated with bilateral cancer (24.9% vs 12.3%, =0.048) in PTC>1.0cm patients. Logistic regression analysis showed that, after adjusting for gender, Hashimoto's thyroiditis and calcification, we found that younger age (<55 years old) (OR: 2.384, 95% CI: 1.241-4.579, =0.009) and V600E mutation (OR: 2.213, 95% CI: 1.085-4.512, =0.029) were significantly associated with lymph node metastasis in PTMC, similar results were not obtained in PTC>1.0cm.
Younger age (<55 years old) and V600E mutation was independent risk factor for lymph node metastasis in PTMC.
关于V600E突变与甲状腺乳头状癌(PTC)临床病理特征、甲状腺微小乳头状癌(PTMC)淋巴结转移风险之间关系的研究结果并不一致。
在这项回顾性分析中,收集患者的临床病理数据,并进行V600E突变的分子检测。将PTC患者分为PTC≤1.0cm(PTMC)和PTC>1.0cm两组,分别分析V600E突变与临床病理特征之间的关系。
520例PTC患者中,女性432例(83.1%),年龄<55岁者416例(80.0%)。422例(81.2%)PTC肿瘤样本检测到V600E突变。不同年龄组V600E突变频率无显著差异。PTMC患者250例(48.1%),PTC>1.0cm患者270例(51.9%)。PTMC患者中,V600E突变与双侧癌(23.0% vs 4.9%,P = 0.005)及淋巴结转移(61.7% vs 39.0%,P = 0.009)显著相关;PTC>1.0cm患者中,V600E突变与双侧癌(24.9% vs 12.3%)显著相关(P = 0.048)。Logistic回归分析显示,校正性别、桥本甲状腺炎和钙化因素后,发现年龄较小(<55岁)(OR:2.384,95%CI:1.241 - 4.579,P = 0.009)和V600E突变(OR:2.213,95%CI:1.085 - 4.512,P = 0.029)与PTMC淋巴结转移显著相关,PTC>1.0cm患者未得到类似结果。
年龄较小(<55岁)和V600E突变是PTMC淋巴结转移的独立危险因素。
