Abstract
To date, thyroglobulin-doubling rate (Tg-DR) and tumor volume-doubling rate (TV-DR) of metastatic lesions have been identified as dynamic prognostic factors for differentiated thyroid carcinoma (DTC). In this study, we investigated the prognostic impact for another dynamic factor, the neutrophil-to-lymphocyte ratio (NLR), for DTC with distant metastasis. We enrolled 321 patients in total, and NLR at the first detection of distant metastasis (initial NLR) was collected for 312. Patients with initial NLR >3 had a significantly poorer cause-specific survival than those with initial NLR ≤3. On multivariate analysis, initial NLR >3 was recognized as an independent prognostic factor together with Tg-DR >1/year, TV-DR >1/year, radioactive iodine-refractory distant metastasis, and distant metastasis to organs other than the lung. Careful observation and active therapies, including multitarget kinase inhibitors, are recommended for patients with NLR >3 at the first detection of distant metastasis or during follow-up.
