[Ultrasonographic screening for thyroid cancer in the screening].
In our hospital, ultrasonography is performed for patients who come for thyroid cancer screening. Seventy-eight patients with thyroid cancer which was found by such screening were operated on from 1989 to 1998, while 287 patients with thyroid cancer found by other methods were operated on during the same period in our department. The age of the patients at surgery in the screening group was younger than that of the contrast group. In the screening group, 41 (52.6%) patients had small thyroid cancer, a higher rate that in the contrast group. Invasion of surrounding organs by the primary cancer was observed in only one patient (1.3%) in the screening group, a rate of invasion that was statistically lower than that in the contrast group. Twenty-six patients with benign thyroid disease detected in our screening were operated on during the same period. Careful selection of patients who need fine-needle aspiration cytology is demanded of head and neck surgeons, and careful evaluation of indicators is necessary to avoid surgery in the case of benign thyroid disease.
