Abstract |
Clinical features of 406 patients with histologically
verified thyroid carcinomas were investigated from May,
1978 to April, 1985 at the Seoul National University
Hospital with the following results. 1) The incidence
of thyroid cancer according to their histological
classification was 79. 8% of papillary carcinoma, 14.5%
of follicular carcinoma, 1.5% of medullary carcinoma,
2.2% of anaplastic carcinoma, 2 cases of squamous
carcinoma and 3 cases of lymphoma. 2) The age
distribution showed the peak incidence in the fourth
decade (25.1%), followed by the fifth and the third
decade. 3) The ratio of male to female patients was
1:6.1. The ratio is 1:5.9 in papillary carcinoma and
1:8.8 in follicular carcinoma. 4) The mean age was 40.2
year in papillary carcinoma, 37.4 year in follicular
carcinoma, 36.5 year in medullary carcinoma, 60.3 year
in anaplastic carcinoma, 62.0 year in squamous
carcinoma, 59.7 year in lymphoma. 5) The diameter of
the thyroid masses was smaller than 1.5cm in 19.9% of
the patients, from 1.5cm to 5cm in 50.5%, from 5cm to
10cm in 25.4% and larger than 10cm in 25.4%. 6)
Metastasis to the regional lymph nodes at diagnosis was
noted in 44.2% of total pa tients, and distant
metastasis was 5%, and local infiltration was 44.2%. 7)
The clinical staging was revealed 42.1% of the patients
in stage Ⅰ, 9.1% in stage Ⅱ, 35.7% in stage Ⅲ, 5.2%
in stage Ⅳ, and 7.9% in undetermined stage. |
