Abstract
Background
Although reoperative surgery in the central compartment (RCND) is indicated for bulky or progressive persistent/recurrent papillary thyroid carcinoma (PTC), its associated morbidity and disease outcomes remain unclear. We evaluated RCND outcomes by comparing them with those of patients who underwent primary central neck dissection (CND).
Methods
After matching for age, sex, tumor size, and initial tumor stage, the morbidity and outcomes of 50 consecutive patients who underwent RCND were compared with data from 75 patients who underwent primary therapeutic CND during the same period. Matching was performed blind to the morbidity and disease outcome of each patient. A stimulated thyroglobulin (sTg) <2 ng/ml was considered undetectable.
Results
Relative to primary CND, the incidence of extranodal extension (p = 0.010) and size of metastatic lymph nodes (p < 0.001) were significantly greater in the RCND group. Postoperative hypoparathyroidism and vocal cord palsy rates were comparable in the groups. There were two esophageal injuries in the RCND group and none in the primary CND group. The secondary CND group achieved a significantly lower undetectable postablation sTg rate (12.0 vs. 52.0 %, p = 0.001) and worse 10-year disease-free survival (35.6 vs. 91.8 %, p = 0.001) and cancer-specific survival (82.0 vs. 98.5 %, p = 0.001) than the primary CND group.
Conclusions
Although RCND for persistent/recurrent PTC was performed with morbidity comparable to that seen with primary CND, it was associated with some serious complications. Short- and long-term disease control appeared moderate with approximately one-tenth of patients having an undetectable sTg level 6 months after ablation and one-third remaining clinically disease-free after 10 years.
