摘要目的 探讨Delphian淋巴结与各临床、病理学因素的相关性,为评估手术范围和判断预后提供临床资料,进一步明确其临床价值.方法 本次调研针对2014年1月-2015年6月于皖南医学院附属弋矶山医院首次手术的经术中冰冻病理证实为甲状腺乳头状癌的69例患者.根据其Delphian淋巴结是否检出及是否转移分别分为两组,用SPSS 22.0统计软件分别对其临床病理学因素进行x2检验或t检验.结果 在已检出Delphian淋巴结的病例中,根据Delphian淋巴结是否转移分为未转移组和转移组,结果示在性别、年龄、肿块大小、桥本氏甲状腺炎及中央区其他淋巴结(COLN,不包括Delphian淋巴结)清扫数目等方面差异无明显统计学意义;多灶性病例为21.05％ vs 57.14％,P=0.047;脉管浸润病例为10.53％ vs71.43％,P＜0.001;COLN转移率为65.79％ vs 14.29％,P=0.011;COLN转移数为(0.84±1.48)vs(3.86±3.08),P＜0.001.由此说明两组在多灶性、脉管浸润及COLN转移概率及转移数目方面有统计学意义.对PTC患者行CD43和D2-40免疫组化标记,可以清晰识别脉管轮廓,脉管侵犯的检出率为17.39％.根据是否存在脉管侵犯,将其分为两组,对比分析其TCLN检出数目(包括Delphian淋巴结)、TCLN转移数目及TCLN转移率,结果示两组清扫的TCLN检出数目差异无统计学意义,但TCLN转移数目[(0.74±1.83)vs(4.50±2.20),P＜0.001]和转移比率(29.82％vs 100.00％,P＜0.001)均有高度统计学意义.结论 Delphian淋巴结阳性的患者,其发生远处淋巴结转移的可能性更大.故建议行甲状腺全切+双侧中央区清扫术,并结合病史及术前影像学检查仔细评估,选择性行颈侧方淋巴结清扫术.另CD34和D2-40可作为评估PTC患者脉管侵犯的重要指标.而出现脉管侵犯的患者,其中央区发生淋巴结转移的数目及比率及发生远处转移的可能性均相应增加,故应根据病史及术前影像学检查适度扩大手术范围,加强术后随访,以尽可能降低术后复发及远处转移率,提高患者的生活质量.

abstractsObjective To study the correlations between DLN and clinical pathological factors and provide clinical data for assessing the operation scopes and prognostic evaluations aims at further clarify its clinical values.Methods The research aimed at the 69 cases who undertook first-time surgery and confirmed thyroid papillary carcinoma by intraoperative frozen pathology from 2013 to 2014 in Wannan Medical college affiliated Yijishan Hospital.The groups was divided by whether the DLN had been detected and metastasized.And we made chi-square test or t test by using SPSS 22.0 to analysis between the clinical and pathological factors.Results The groups was divided by whether DLN had been metastasized from the detected cases and the results shown that there was no relationship with gender,age,tumor size,Hashimoto's thyroiditis and the number of COLN (which not including DLN).For multifocal cases (21.05％ vs 57.14％,P =0.047);for vascular infiltration,the positive cases of (10.53％ vs 71.43％,P＜0.001);for the metastasized rate of COLN,the positive cases of (65.79％ vs 14.29％,P =0.011);for the metastasized number of COLN,[(0.84 ± 1.48) vs (3.86 ± 3.08),P ＜ 0.001].All the data above illustrated that the two groups are statistically correlative in mulifocality,vascular infiltration,the metastasized rate of COLN and for the metastasized number of COLN.17.39％ of PTC cases can be detected by CD34 and D2-40.According to the presence of vascular infiltration,it can be divided into two groups,We contrast analyzed of the number of TCLN (include DLN),metastasized number of TCLN and the metastasized rate of TCLN.The results shown that the number of TCLN had no statistical differences,but significant in metastasized number of TCLN [(0.74 ± 1.83) vs (4.50 ± 2.20),P ＜ 0.001) and the metastasized rate of TCLN (29.82％ vs 100.00％,P ＜ 0.01)].Conclusions The DLN positive patients are more likely to have distant lymph node metastasized.If DLN positive,total thyroidectomy and bilateral central compartment neck dissection (CCND) has been necessary.Lateral selective neck node dissection (LSND) can be underwent after evaluating carefully combining with the history and preoperative images.CD34 and D2-40 could be the detection indexes of vascular infiltration for PTC.For the cases with vascular infiltration,it has a higher proportion to have the metastasized number and metastasized rate of TCLN and higher possibility of distant metastasis.So we should expand the scope of operation moderately and strengthen postoperative follow-up according to the history and preoperative images so as to reduce postoperative recurrence,distant metastasis rate and improve the living quality of patients.
