Abstract:

Objective To discuss the risk factors of recurrence of papillary thyroid microcarcinoma (PTMC),and to provide the reference for the individualized diagnosis and treatment of PTMC. Methods The retrieval time was limited from the establishment to April 2022, and the case-control studies related to PTMC recurrence searched in PubMed, EMBase, Elsevier Science Direct and Web of Science Databases were collected.Review Manager 5.4 software was used to perform the Meta-analysis and ADDIS 1.16.8 software was used to make the Bayesian network Meta-analysis,and the risk factors of PTMC recurrence were screened out and ranked. Results Fourteen studies were included, involving 7 834 PTMC patients who underwent surgical treatment,302 patients experienced lymphnode recurrence, local thyroid bed recurrence, or distant metastasis recurrence. Age, multifocality, tumor size, extrathyroidal invasion, lymphnode metastasis, and vascular invasion of the patients were related to the PTMC recurrence (P<0.05). Lymphnode metastasis was the most significant risk factor for the PTMC recurrence, followed by vascular invasion, and multifocality was the least significant risk factor. There were no significant correlations between gender, lesion histopathological background, gland histopathological background, radioactive iodine treatment, surgical margin, and the extent of thyroidectomy with PTMC recurrence (P>0.05). Conclusion Lymphnode metastasis, vascular invasion, tumor size>5 mm,age,extrathyroidal invasion, and multifocality are the risk factors for the PTMC recurrence.The clinician may consider to treat the PTMC patients with routine central lymphnode dissection to prevent disease recurrence,and develop the individualized treatment plans based on the risk factor stratification.
