Clinical significance of microcalcification in patients with thyroid micropapillary carcinoma / 中国耳鼻咽喉头颈外科

ABSTRACT

OBJECTIVE To investigate the clinical significance of microcalcification under high resolution ultrasonography in predicting thyroid micropapillary carcinoma(PTMC) and cervical lymph node metastasis. METHODS The clinical data of 388 patients with papi l lar y thyroid microcarcinoma were analyzed retrospectively in Beijing Tongren Hospital from Jan 2013 to Jun 2017, which included patients' clinical ultrasonographic features and pathological results in this study. Pearson correlation analysis and data fitting modeling were used to analyze the microcalcification, the maximum diameter of the tumor and the cervical lymph node metastasis in the central region. RESULTS The incidence of microcalcification in PTMC patients was closely related to the maximal diameter of the tumor. The tumor diameter of PTMC was related to the lymph node metastasis rate in the central region of the neck, and it was not found that microcalcification was associated with lymph node metastasis in the central region of the neck. CONCLUSION The weight of microcalcification in the diagnosis of PTMC is related to the maximum diameter of the nodule. Furthermore, patients with thyroid nodules having a tumor diameter of less than 1 cm, with the larger diameter of tumor nodules, the greater the risk of PTMC, the more recommended fine needle biopsy.
