摘要
Objective:The aim of this study was to explore the relationship between follicular carcinoma of thyroid in different risk groups and lymph node micrometastases.Methods:The keratin-19 of negative neck lymph nodes in 83 cases in routine pathological examination,was detected by SP immunohistochemistry using keratin-19 monoclonal antibody to confirm lymph node micrometastases.All of cases are divided into high risk group,middle risk group and low risk group according to factors related prognosis,the relationship between lymph node micrometastases and different risk groups and follow-up visit documents were analyzed.Results:Fifty-eight neck lymph nodes in 16 cases of 83 cases(19.3%) showed positive lymph node micrometastases,and incidence of lymph node micrometastases was 4/39 in low risk group,5/32 in middle risk group and 7/12 in high risk group,respectively.it showed remarkable difference during 3 groups(P < 0.001).Nine patients in 16 cases with positive lymph node micrometastases showed local recurrence and distant metastases,6 patients in 67 cases with negative lymph node micrometastases showed same result(P < 0.001).Conclusion:Lymph node micrometastases in follicular thyroid carcinoma closely correlated to factors related to prognosis.The detection of lymph node micrometastases can directly assistant postoperative treatment and prognosis evaluation to some extent for follicular thyroid carcinoma.
