ABSTRACT
Objective To explore risk factors of recurrence in papillary thyroid microcarcinomas ( PTMC ) and papillary thyroid carcinomas with 1-2 cm diameter. Methods From January, 2008 to December, 2010 in PLA General Hospital, 323 eligible patients received first surgery and diagnosed pathologically with papillary thyroid cancer≤2 cm were analyzed retrospectively. According to rumor size, patients were divided into PTMC and PTC of 1-2 cm, which were investigated recurrence factors. Results Finally we indentified 320 PTC≤2 cm, including 218 (68.1%)PTMCand102(31.9%)PTCof1-2cmwithamedianfollow-uptimeof72.5(55-90)months.32cases (10%)of patients relapse, includig 22 cases(10%)in PTMC and 10 cases(9. 8%)in PTC of 1-2 cm. In the clinical characteristics analyses of PTC≤2 cm, the PTC of 1-2 cm was different from PTMC in age, lymph node metastasis and TNM stage. The univariate analysis showed that tumor location and lymph node metastasis influenced recurrence of PTMC and PTC of 1-2 cm,while tumor foci and extrathytoidal extension were risk factors of recurrence in PTMC but not in PTC of 1-2 cm. Lymph node metastasis was independent factor which influenced the recurrence of PTMC and PT C of 1-2 cm according to COX multivariate analysis. Conclusion Disease recurrence did not differ significantly between the PTMC and PTC of 1-2 cm and lymph node metastasis was an independent recurrence factor.
