Disease characteristics.

aData are medians with interquartile range (25th and 75th centile) in the groups “All patients, n = 121” and “Patients with undetectable Tg-Tg-on”, N = 115”. Data are medians and range in the groups “Patients with Tg-on 0.6–1.0 ng/ml, N = 3”and “Patients with Tg-on >1.0, N = 3”. bTNM-classification and staging according to Hermanek & Sobin, 1992 [34]. cLow-risk patients are stage I disease if younger than 45 years or Stage I or II if older than 45 years.a 本数据为“所有患者（n=121）”与“Tg-Tg-on不可测患者（N=115）”两组的中位数及四分位间距（25th与75th百分位数）。 本数据为“Tg-on 0.6~1.0 ng/ml患者（N=3）”与“Tg-on>1.0患者（N=3）”两组的中位数及极差。 b TNM分类与分期依据Hermanek与Sobin 1992年发表的文献[34]。 c 低危患者定义为：年龄小于45岁者为Ⅰ期疾病，年龄大于45岁者为Ⅰ期或Ⅱ期疾病。
