Abstract:
Objective To analyze of the prevalence of encapsulated follicular variant of papillary thyroid carcinoma (EFVPTC) and noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) by 2017 World Health Organization ( WHO) classification of tumors of endocrine organs in Guiyang. Methods A retrospectively analysis of patients who had a thyroid surgery and confirmed thyroid cancer by pathological diagnosis in the Affiliated Hospital of Guizhou Medical University from 2009 to 2016. PTC and FVPTC by 2014 WHO classification of tumors of endocrine organs , and according to the 2017 WHO classification of tumors of endocrine organs ,the thyroid papillary carcinomas were reviewed and some had been confirmed as EFVPTC and NIFTP, with analysis of the prevalence and prognosis of NIFTP. Results Of the 1207 cases of thyroid carcinoma, 1150 cases were papillary carcinoma, the constituent ratio of thyroid carcinoma was 95.28％, the FVPTC was 72 cases, and the proportion of thyroid carcinoma was 5. 97％; the proportion of FVPTC in thyroid carcinoma decreased from 2009 to 2016 ( P <0.05). After pathological sections being reviewed, 10 cases had been confirmed as non-encapsulated infiltrative FVPTC, the ratio of thyroid cancer to thyroid cancer was 0.83％; EFVPTC was found in 62 cases, accounting for 5.14％ of thyroid carcinoma, these included 2 cases of NIFTP confirmed by the 2017 WHO classification of tumors of endocrine organs and 60 cases encapsulated invasive FVPTC, the percentage of thyroid carcinoma was 0.17％ and 4.97％. 62 cases of EFVPTC with the exception of 11 cases without further visit, while the remaining 51 cases of EFVPTC were followed up. Death, local or distant metastases were defined as adverse events. An adverse event was seen in 11 of 49 of the cases of invasive EFVPTC, including 2 died of disease; The NIFTP were alive with no evidence of disease. Conclusion The diagnosis of NIFTP according to new WHO classification of endocrine organ tumors in 2017 has little expected impact in Guiyang.
