Background.
Recently, several studies have reported that dedifferentiation occurs in fatal well-differentiated thyroid cancer (WDTC) cases.
This study aimed at investigating the clinicopathological characteristics of WDTC undergoing dedifferentiation.
Methods.
A total of 63 WDTC patients harboring dedifferentiated phenotype were enrolled in the study.
The Kaplan-Meier method and Cox regression analysis were used to perform survival analyses.
Harrell index of concordance (C-index) and Akaike information criterion (AIC) were calculated to compare the predictive value for prognosis among several prognostic classification systems.
Results.
The median cause-specific survival (CSS) of patients was 138 months, with the CSS rate of 64.0% and 53.3% at 5 and 10 years, respectively.
Presence of the anaplastic thyroid cancer (ATC) phenotype significantly increased the risk of poor CSS (P=0.033), and age was the only independent risk factor for disease progression (P=0.015).
The C-index and AIC of the age, grade, extent, size (AGES) prognostic classification system for the CSS were 0.723 and 59.937, respectively.
Conclusions.
The presence of dedifferentiated phenotypes can be responsible for the poor outcomes in WDTC patients.
The AGES system demonstrates to be an optimal prognostic system for WDTC undergoing dedifferentiation.
