Abstract
This is a retrospective review of 409 cases of papillary thyroid cancer treated at the Hospital of Oncologia, National Medical Center, IMSS in Mexico City. The clinical features, histopathologic findings, analysis of recurrences and survivals according to age, sex, tumor size, and modality of treatment are described. The results showed that tumoral diameter > 5 cm, distant metastasis at diagnosis, age > 40 years, and tumoral infiltration beyond the thyroid capsule significantly affect the patient's survival.
