Tumor size rather than the thyroid invasion affects the prognosis of parathyroid carcinoma without lymph node or distant metastasis

ConclusionThyroid invasion, which was the criterion forT1 andT2 staging criteria of parathyroid carcinoma according to the AJCC, did not affect the prognosis of patients with parathyroid carcinoma without local lymph node or distant metastasis. Our study indicates that a tumor size  ≥ 4 cm may be an appropriate indicator ofT1 andT2 cancer staging.
