Summary
Gross extranodal extension (gENE) in differentiated thyroid carcinoma predicts recurrence. Patients with gENE and intermediate risk may require high-risk management due to similar outcomes to high-risk non-gENE patients.
Area of Science:
- Oncology
- Pathology
- Surgical Oncology
Background:
- Differentiated thyroid carcinoma (DTC) recurrence is a significant clinical concern.
- Accurate risk stratification is crucial for effective patient management.
- The prognostic role of gross extranodal extension (gENE) in DTC requires further elucidation.
Purpose of the Study:
- To investigate the predictive value of gENE for DTC persistence and recurrence.
- To determine if gENE is an independent risk factor for DTC recurrence.
- To explore the impact of gENE-specific features on DTC outcomes.
Main Methods:
- Retrospective study of 989 patients with DTC.
- Patients were categorized into gENE and non-gENE groups.
- Comparison of disease persistence/recurrence rates between groups, including by risk stratification (intermediate/high).
Main Results:
- The gENE group exhibited higher persistence/recurrence rates than the non-gENE group (P < .05).
- gENE was an independent predictor of recurrence (OR, 2.89; P = .005).
- Intermediate-risk gENE patients had outcomes similar to high-risk non-gENE patients (P = .72).
Conclusions:
- gENE is a significant independent predictor of DTC recurrence.
- Patients with gENE and intermediate risk may warrant reclassification as high-risk.
- Specific gENE features do not appear to influence recurrence risk.
