Central compartment lymph node metastasis in cN0 papillary thyroid carcinoma / 中华普通外科杂志

ABSTRACT

ObjectiveTo evaluate central compartment lymph node metastasis in cN0 papillary thyroid carcinoma(PTC) patients. MethodsThe clinical data of 166 cN0 PTC patients was retrospectively analyzed. ResultsThe central compartment lymph node metastasis rate of age ＜ 45 years group was higher than the group of age≥45 years(39％ vs.22％,P ＜0.05).Tumor size ＞0.5 cm tends to metastasize more often than tumor size ≤0.5 cm(P ＜0.05) ; there was significantly difference in central compartment lymph node metastasis rate between upper pole tumor ( 25％,12/48 ) and middle ( 45％,13/29 ) or lower pole (43％,31/72),P ＜ 0.01. ConclusionscN0 PTC patients with tumor located in middle pole or lower pole,tumor size ＞ 0.5 cm or age ＜ 45 years are at higher risks for central compartment lymph node metastasis.
