Table 4.
Thyroglobulin values according to therapeutic responses.
| Thyroglobulin (ng/mL) | Tumor Free | Uncertain | Incomplete Biochemical Response | Structural Disease |
|---|---|---|---|---|
| Median (Quartiles) | ||||
| Postoperative | 9.8 (3.2–19.7) | 23.0 (9.7–52.1) | 45.4 (16.3–60.7) | 215.0 (65.0–638.0) |
| After 9–12 months | 0 (0–0) | 0.5 (0–1.0) | 1.7 (1.3–5.7) | 21.6 (4.3–104.4) |
| At the end of follow-up | 0 (0–0) | 0.5 (0.4–0.6) | 2.0 (1.4–3.0) | 19.1 (7.8–117.0) |
| The lowest | 0 (0–0) | 0.1 (0–0.4) | 0.9 (0.6–1.9) | 10.2 (3.0–40.0) |
| The highest | 0.2 (0–0.5) | 1.5 (0.6–2.4) | 5.0 (2.0–8.8) | 63.7 (11.4–1254.0) |
All differences were significant between groups (Kruskal–Wallis test; p < 0.01) except the postoperative thyroglobulin value between uncertain and incomplete biochemical response groups.
