Tumor vascularity predicts recurrence in differentiated thyroid carcinoma

Summary
Tumor microvessel density (MVD) is a potential new prognostic indicator for differentiated thyroid carcinoma. High MVD and thymidine phosphorylase (dThdPase) expression may identify patients needing adjuvant radiotherapy.
Area of Science:
- Oncology
- Pathology
- Surgical Oncology
Background:
- Differentiated thyroid carcinoma (DTC) requires new prognostic markers.
- Optimizing extent of thyroidectomy and adjuvant radiotherapy is crucial for DTC management.
Purpose of the Study:
- To investigate tumor microvessel density (MVD), thymidine phosphorylase (dThdPase) expression, and CD68-stained macrophages as prognosticators in DTC.
- To explore the relationship between these markers and clinical outcomes, including recurrence-free survival.
Main Methods:
- Immunohistochemical evaluation of MVD, dThdPase, and CD68 in 71 DTC specimens.
- Correlation analysis between marker expression, tumor size, and recurrence-free survival.
Main Results:
- Hypervascular tumors (high MVD) were associated with significantly shorter recurrence-free survival (P <0.05).
- A significant positive correlation was found between dThdPase expression and MVD (R = 0.323, P <0.001).
- High MVD and dThdPase expression were more frequent in tumors larger than 3 cm; high dThdPase correlated with CD68-positive macrophages (P <0.001).
Conclusions:
- Tumor MVD shows promise as a novel prognostic indicator for differentiated thyroid carcinoma.
- Combined high MVD and dThdPase expression may identify a subset of DTC patients who could benefit from adjuvant radiotherapy.
