再多引一段：”Moreover, Hartl et al. 33 recently reported a high rate of multi-focality and lymph node metastases. They found foci of carcinoma in thyroid lobes in 56% of patients and 75% had lymph node metastases, in both central and lateral compartments 33. However, overall prognosis is favourable for the majority of patients 31 32.“

这岂不是说有人报道56%的发病率了吗？prognosis 还不错。要看看那几篇具体文献吧，至少那些病人都是什么情形。。。

否则，嘿嘿，老方该认输啦。。。。
