| Objective:By analyzing the patient’s medical records to identify factors ofcervical lymph node metastasis in papillary thyroid cancer, thesurgical neck dissection line ranges provide a clinical basis.Methods:Collected January1,2014-October31,2014by postoperativepathology paraffin-Japan Friendship Hospital of Jilin Universitythyroid surgery treated papillary thyroid cancer confirmed a total of1713cases,355cases were male, female1358cases; the age of14-77years, mean age43years,≤45years were1079cases,>45years of age634cases;389cases of patients with invasion andcoating; multifocal cancer,757cases;956cases of cancer a singlelesion, which is located on the pole184Example, in the middle of310cases,452cases located under the pole, located in the left lobe453cases,10cases of isthmus, located in the right lobe493cases.All patients underwent thyroid cancer central lymph node dissection,the line side of neck lymph node dissection in599cases. Thestatistics of the results, the application SPSS19.0statisticalsoftware for statistical analysis, data were X2test, P <0.05wasconsidered statistically significant, P <0.001for the difference washighly statistically significant. Analysis of patients with thyroidcancer foci location, gender, age, is an infringement of the size ofthe tumor capsule, tumor foci relationship between the number oflymph nodes and the central and lateral cervical lymph node metastasis, as well as central and lateral cervical lymph nodemetastasis the relationship between lymph node metastasis, in orderto identify the factors that influence the occurrence of cervicallymph node metastasis.The result:1713cases of thyroid patients, the central area and the side ofthe neck metastasis in papillary were:41.4%,52.4%of men andwomen had central lymph node metastasis rates were:57.7%,37.1%(P <0.001); side neck metastasis. rates were:57.3%,50.7%(P=0.152).≤45years and>45years central lymph node metastasisrates were:47.5%,31.1%(P <0.001); side neck metastasis rateswere:55.6%,45.5%(P=0.021). Tumor invasion and film coatingand not invading Central District metastasis rates were:50.1%,38.8%(P <0.001), side neck metastasis rates were:57.4%,50.1%(P=0.096). Cancer D≤1cm with D>1cm central district transfer rateswere:35.6%,66.2%(P <0.001); side neck metastasis rates were:45.1%,63.1%(<0.001). Single lesion cancer and multifocal cancermetastasis rates were central district:36.1%,48.1%(P <0.001); sideneck metastasis rates were:49.4%,54.6%(P=0.209). The numberof central lymph node metastasis <3and≥3pieces, its side-neckedzone transfer rates were:36.2%,82.4%(P <0.001), papillary thyroidcarcinoma (a single lesion) foci located in the upper, middle andlower when Central District metastasis occurrence rates were:33.2%,31.9%,40.1%(P=0.048); side neck metastasis rates were:59.4%,49.4%,43.5%(P=0.133). PTC (single lesion) foci in theleft lobe, isthmus, the right lobe, the central area of the transferrates were:33.1%,40.0%,38.7%(P=0.191); PTC (single lesion)foci in the left lobe and right Ye, the incidence side neck metastasis was46.2%,52.9%(P=0.287). PTC (single lesion) foci located onthe middle and lower pole, its central lymph node metastasis rateswere:32.4%,40.1%(P=0.014); lateral cervical lymph nodemetastasis rates were:53.8%,43.5%(P=0.105)Conclusion:1: papillary thyroid carcinoma central lymph node metastasisrate, initial surgery should be routine central lymph node dissection;2: male, young, tumor invasion and coating, multiple foci of cancerin high-risk papillary thyroid cancer lymph node metastasis factors;3: foci long diameter size and the central region and the side necklymph node metastasis were correlated; the risk factors for cervicallymph node metastasis effects;4: thyroid cancer foci position is afactor central lymph node metastasis, tumor located in a verycentral area more prone to lymph node metastasis;5: Number oflymph node metastasis in the central area≥3pieces, the side is arisk factor for cervical lymph node metastasis, can be used as sideneck lymph node dissection reference. |
