BACKGROUND: The impact of nodal disease remains controversial in papillary thyroid carcinoma (PTC). STUDY DESIGN: One surgeon treated 159 unselected patients, who were followed up for 1 to 27 years. We present a retrospective analysis with respect to nodal disease. Occult nodal disease was investigated, including metachronous nodal disease (mpN(1)) in primarily node negative patients (pN(0), clinical [c]N(0)). RESULTS: Therapeutic lymphadenectomies, prophylactic lymphadenectomies, or no lymphadenectomy were carried out in 42 (cN(1)), 29 (cN(0)), and 88 (cN(0)) patients, respectively, with stage pN(1) in 41 (98%), in 5 (17%), and in 2 (2.3%) patients, respectively (17% versus 2.3% p < 0.005). Sensitivity and specificity of clinical staging were 85% and 99%, respectively. More frequent prophylactic lymphadenectomy during the study period (p = 0.002) led to a nonsignificant increase in stage pN(1) (26% versus 30%). Immunohistochemistry led to upstaging of only 3% of histologically negative nodes and one (4%) pN(0) patient. Nodal recurrence occurred in 8 of 156 patients (5%) treated for cure, in 12% of pN(1) versus 3% of pN(0) cN(0) tumors (p = 0.009), in 15% of TNM high-versus 3% of low-risk patients (p = 0.006), and in 5% each of patients, younger than 45 and 45 years or more. In TNM high-risk patients, tumor-related survival was 50% for stage pN(1) versus 86% for stage pN(0), cN(0) (p = 0.03) (100% and 100% in low-risk patients). CONCLUSIONS: The rate of occult nodal disease m...
