Abstract:
BACKGROUND:New prognosticators are necessary for optimizing the extent of thyroidectomy and adjuvant radiotherapy in differentiated thyroid carcinoma. METHODS:Tumor microvessel density (MVD), expression of thymidine phosphorylase (dThdPase) and CD68 stained macrophages were evaluated in 71 differentiated thyroid carcinomas by an immunohistochemical method. RESULTS:The recurrence-free survival was significantly (P <0.05) shorter in patients with hypervascular tumors but was not related to the dThdPase expression. Significant (R = 0.323, P <0.001) correlation between dThdPase expression score and increment in MVD was documented. Frequent high MVD and dThdPase expression were encountered in tumors >3 cm. Twenty-two of the 27 (82%) patients expressing high dThdPase were also evaluated positive for CD68 (P <0.001). CONCLUSIONS:Tumor MVD might be a new prognostic indicator of differentiated thyroid carcinoma, whereas dThdpase expression with high MVD might serve to identify a subgroup of thyroid carcinoma patients as potential candidates for adjuvant radiotherapy.
