王旭教授认为甲状腺癌术后患者的病机总属本虚标实，基本病机为肝郁气滞、脾失健运，在疾病发展过程中可兼夹血瘀、痰凝，但肝气乘脾的基本病机贯穿始终，病久可累及心、肺、肾。治疗上以调和肝脾为核心，兼顾他脏，并将甲状腺癌术后分为3期，认为疾病初起主要涉及肝脾，疾病中期累及心肺，疾病后期脾病及肾，且有久病入络之虞，故在不同时期根据病位所在，辨证论治，并中西贯通。

Professor WANG Xu holds that the disease mechanism of thyroid cancer after surgery are mainly deficient root and excessive branch. The primary disease mechanism are liver qi stagnation and spleen failing to transport,and in the course of disease development,there are often with blood stasis and phlegm coagulation.The primary disease mechanism liver qi attacking spleen is present in the whole course,and heart,lung and kidney are usually involved finally. On treatment,the core is to harmonize liver and spleen,supplemented by treating other Zang orangs. The thyroid cancer after surgery could be divided into three stages. In the early stage it mainly involves liver and spleen,in the middle stage involves heart and lung,and in the late stage involves kidney,as well as affecting collaterals. Therefore,according to different stage and disease location,treatment based on syndrome differentiation should be conducted in combination with western medicine.
