Prognostic factors and risk group analysis are very well known in well differentiated thyroid cancer. One of the major prognostic factors is presence of extrathyroidal extension and residual gross tumor. It is not uncommon to find the final pathology report showing minimal extrathyroidal extension. The debate continues as to the implication of this microscopic or minimal extrathyroidal extension. The previous staging system had upstaged such tumors. However, several reports in the literature suggest no prognostic implication of microscopic or minimal extrathyroidal extension.
在高分化甲状腺癌中，预后因素和风险组分析广为人知。主要预后因素之一是甲状腺外侵犯和肉眼可见的残留肿瘤。最终病理报告显示微小甲状腺外侵犯并不罕见。关于这种微小或极小的甲状腺外侵犯的意义，争论仍在继续。先前的分期系统将这类肿瘤进行了更高分期。然而，文献中的几份报告表明，微小或极小的甲状腺外侵犯并无预后意义。
