Notes
: Basis for Detection Rates
1. Precancerous Lesion Detection Rate (Based on 100% follow up): defined as precancerous lesion cases/number of
screenings
2. Cancer Detection Rate (based on 100% follow up): cancer cases/number of screenings
3. Overall Detection Rate (based on 100% Follow up): (precancerous lesions + cancer cases)/number of screenings
4. 1/Detection Rate = number of people who must be screened on average to detect one positive case

Notes
: 1. Analyzed hospital-reported data on the five-year survival rate for four major types of cancer by stage, from 2015 to 2019 (patient tracking through 2020)
2. According to the screening data and five-year survival rates for patients diagnosed with stages 0 and 1 oral cavity cancer by MOHW, approximately 65% of the stage 0 cases have been classified under "precancerous lesions" in actual practice. Consequently, the number of stage 0 cases (306 entries) has significantly less compared to that of stage 1 cases (7,906 entries). This in turn has caused significant fluctuations in the data for survival rate.
3. Relative 5-year survival rate: the corrected competing risk survival rate would be the survival rate from the cancer. Relative survival rate = Observed survival rate / Expected survival rate x100%.
