Abstract

The study of histopathological variants’ rate of papillary thyroid carcinoma is according to World Health Organization’s classification in 2017. Objective: Determine the variants’rate of papillary thyroid carcinoma. Subjects:Includes 99 patients with diagnosis of papillary thyroid carcinoma, who had total thyroidectomy and lymph node dissectionfrom 01/2019 to 01/2021 in Viet Nam National Cancer Hospital, Tan Trieu campus. Sampling was purposive and took all cases. Research methods: The cross-sectional descriptive study was done. All research cases had full enough information about age, gender, tumor site, gross after surgery. The suspicious cases in HE were stained by immunohistochemistry to dertermine the orgin and/or tumor subtypes. Results and conclusion: The disease’s average-age was 37,5 ± 14,9 years old, the rate of women/men was 7,3/1;tumors were usually in the right robe with 43,4%. 10/15 variants were determined and their rate as following:  Conventional variant (21,2%), papillary microcarcinoma (17,2%), diffuse sclerosing variant (16,2%), tall cell variant (16,2 %), encapsulated variant (11,1%), follicular variant (9,1%), oncocytic variant (6,0%) and 1 % other variants with cribriform – morular variant, warthin-like variant and solid variant. All research results were compared and discussed.
