Tokyo Dental College started oral cancer screening in cooperation with a local dental association in 1992. Reveal the usefulness of Countermeasure and Opportunistic Screening Systems for Oral Cancer. The actual results of countermeasure and opportunistic oral cancer screening systems are reported.
Countermeasure screening for the public was performed in each region, and opportunistic screening was performed in a general dental clinic of a cooperating physician.
In countermeasure screening, 19,721 persons were checked from 1992 to 2018; the gender ratio was 1:3. The close examination rate was 4.45%. The detection rates of oral cancer and oral potentially malignant disorders were 0.13% and 1.85%, respectively. In opportunistic screening, 29,912 persons were checked from 2006 to 2018; the gender ratio was 2:3. The close examination rate was 2.33%. The detection rates of oral cancer and oral potentially malignant disorders were 0.08% and 2.15%, respectively. The close examination rate was significantly lower in opportunistic screening than in countermeasure screening. The oral cancer detection rates and the positive predictive value for cancer were equivalent. In addition, the detection rate of oral potentially malignant disorders was significantly higher in opportunistic screening than in countermeasure screening.
Oral cancer detection rates were equivalent between countermeasure and opportunistic screenings, and opportunistic screening were more effective on number of participants and the close examination rate, and the detection rate of oral potentially malignant disorders.
东京齿科大学于 1992 年与当地牙科协会合作开始进行口腔癌筛查。揭示口腔癌对策性和机会性筛查系统的有效性。报告了对策性和机会性口腔癌筛查系统的实际结果。
在每个地区进行公众对策性筛查，在合作医生的普通牙科诊所进行机会性筛查。
在对策性筛查中，1992 年至 2018 年共检查了 19721 人，性别比为 1:3。精密检查率为 4.45%。口腔癌和口腔潜在恶性疾病的检出率分别为 0.13%和 1.85%。在机会性筛查中，2006 年至 2018 年共检查了 29912 人，性别比为 2:3。精密检查率为 2.33%。口腔癌和口腔潜在恶性疾病的检出率分别为 0.08%和 2.15%。机会性筛查的精密检查率明显低于对策性筛查。口腔癌的检出率和癌症的阳性预测值相当。此外，机会性筛查的口腔潜在恶性疾病的检出率明显高于对策性筛查。
对策性和机会性筛查的口腔癌检出率相当，机会性筛查在参与者人数和精密检查率以及口腔潜在恶性疾病的检出率方面更有效。
