Spontaneous Slowing and Regressing of Tumor Growth in Childhood/Adolescent Papillary Thyroid Carcinomas Suggested by the Postoperative Thyroglobulin-Doubling Time

Figure 1

Comparison of hTV-DT and Tg-DT values. hTV-DT: the preoperative hypothetical tumor volume-doubling time; Tg-DT: the postoperative thyroglobulin-doubling time. Two patients showed a decrease in their serum Tg values over time, and thus their Tg-DTs are shown as negative values.
