Abstract: Objective To analyze the risk factors of central compart-ment lymph node ( CCLN) metastasis in papillary thyroid micro carcino-ma ( PTMC ) without clinical cervical lymph node metastasis ( cN0 ) , according to the general situation of paratracheal lymph node metastasis in PTMC.Methods Clinical data of 120 PTMC ( cN0 ) patients who underwent radical thyroidectomy and CCLN dissection were retrospective-ly analyzed.Patients were divided into CCLN positive group ( 40 cases ) and CCLN negative group (80 cases) according to postoperative pathology results, and the risk factors were analyzed.Results The CCLN metasta-sis rate of PTMC was 33.3%.Position ( P<0.05 ) , capsular invasion (P<0.05), multifocal PTMC (P<0.01) were the risk factors of CCLN metastasis.Conclusion The ( cN0 ) PTMC has a high rate of pathologi-cal CCLN metastasis.It is imperative to conduct the thyroidectomy with ipsilateral level Ⅵ lymph node dissection in PTMC patients , especially those with related risk factors.
