Abstract 6073

Background

Thyroid carcinomas are fairly uncommon tumors. They include disease types that range from indolent behavior such as papillary carcinomas to the fulminant and lethal anaplastic disease. The aim of this study was to analyze the characteristics of patients diagnosed with thyroid carcinoma in the United States between 2000 till 2016.

Methods

This study was conducted using SEER*Stat version 8.3.5 to analyze clinical and pathological characteristics of thyroid carcinoma patients diagnosed in the period between 2000 and 2016 in the United States through exploiting the data obtained from SEER Regs Research Data Nov 2018. The data were statistically analyzed using SPSS version 20.

Results

A total of 172525 cases of thyroid carcinoma were diagnosed. The median age at diagnosis was 50 years. Females were the most common gender affected (n = 131059; 75.7%). The incidence rate of thyroid carcinoma was estimated to be 12 per 100,000 cases. Papillary adenocarcinoma, NOS was the most common histology (n = 84323; 48.7%), followed by follicular variant of papillary carcinoma (n = 46830, 27.1%). The disease was the only primary tumor in most of cases (n = 139831; 80.8%). The majority of patients had localized early disease at the time of diagnosis (Stage I = 89235; 51.5%), and surgery was performed in the vast majority of case (n = 164742; 95.2%). The median survival wasn’t reached, with observed survival, at 5 and 10 years, was 94.2% & 89.2% respectively and relative survival at 5 and 10 years was 98% & 97.4%, respectively.

Conclusions

Thyroid carcinoma is a disease of middle ages, mainly, with female predominance. Papillary thyroid carcinoma is the most common histology and most of patients tend to present at early stage. The survival is good with median survival wasn’t reached and relative 5- year and 10- year survival of 98% & 97.4%, respectively.
