Background and Objectives
In papillary thyroid cancer (PTC), the adverse prognostic impact of extrathyroidal extension (macro‐ETE) invading the subcutaneous soft tissues, larynx, trachea, esophagus, or recurrent laryngeal nerve (T4a disease) is well established. We investigated whether the extent of macro‐ETE, defined as “limited” with single structure involvement (lim‐ETE) and “extensive” with multiple...
Background
Although microscopic positive margins appear to have no independent prognostic impact in papillary thyroid cancer (PTC), this may not be the case in pT4a tumors.
Methods
Retrospective analysis of 610 patients with PTC, 39 with pT4a tumors, to determine if microscopic positive margins impact disease‐free survival (DFS) in pT4a PTC.
Results
On univariate analysis, microscopic positive...
