This paper reports the result of the first mass screening for laryngeal carcinoma performed in October, 1982 in the Kanto area. In order to make the screening an efficient and precise means to detect early laryngeal cancer, we have done various preliminaly studies for these 5 years, the details of which have been described in our two previous reports.The screenees consisted of 1223 people, of whom 825 were regarded as "at high risk" because of their sex (men), ages (50 and over), and presenting symptoms (especially, hoarseness). The screening was carried out by 46 practicing otolaryngologists in Tokyo during the period from Oct. 1 to Oct. 31, 1982, which makes one to ten screenees examined daily by one doctor.Six laryngeal cancers were detected in this screening, including four T1 cases, one T3 case and one T4 case. The detection rate was 0.73%, considerably high in comparison with the rate of below 0.1% in the mass screenings for other cancers, such as lung, stomach, cervical and breast cancers.The first mass screening for laryngeal cancer was quite successful. We believe the regular and nation-wide application of this program will contribute to the early detection and the better prognosis of laryngeal cancer and will provide many patients greater chances to preserve their voices.
