Clinical Significance of Circulating Tumor Cells (CTCs) and Survivin on Predicting Prognosis in Thyroid Cancer Patients

Figure 3

PFS of patients with CTCs and MCTC by Kaplan-Meier curves at diagnosis. (a) PFS in >6 CTCs vs. ≤6 CTCs of PTC patients; (b) PFS in >6 CTCs vs. ≤6 CTCs of FTC patients; (c, d) PFS comparison with MCTC vs. without MCTC in PTC and FTC patients. PTC: papillary thyroid cancer; FTC: follicular thyroid cancer; CTCs: circulating tumor cells; MCTC: mesenchymal circulating tumor cell.
