Tumor Volume Kinetic Analyses Might Explain Excellent Prognoses in Young Patients with Papillary Thyroid Carcinoma

Figure 1

Comparison of TV-DRs and hTV-DRs. The difference in TV-DRs was calculated using the Wilcoxon signed-rank test. In the 20 patients, the TV-DRs after diagnosis were smaller than the hTV-DRs, and seven patients had negative values, suggesting slowing or regression of the tumors (). TV-DR: tumor volume-doubling rate after presentation; hTV-DR: hypothetical tumor volume-doubling rate before presentation.
