title: [Clinico pathologic analysis of 1503 thyroid tumors].
abstract: A clinicopathologic analysis of 1503 thyroid tumors was conducted revealing 82.9% of benign and 17.8% of malignant lesions. The most common type of benign tumor was simple adenoma (62.1%) and of malignant tumor, papillary adenocarcinoma (52.5%). The malignant to benign tumor ratio was 1:4.8. The male to female sex ratio was 1:2.6 in the malignant and 1:3.8 in the benign tumors. The overall 5- and 10-year survival rates for all cancers were 67.7% and 47.6%, respectively. It is suggested that the follicular carcinoma could further be divided into well differentiated (papillary and follicular), poorly differentiated (including squamous cell carcinoma) and undifferentiated types.
