[Reporter Lin Huiqin/Taipei Report] Since July 1 this year, the National Health Administration of the Ministry of Health and Welfare has offered to subsidize the high-risk groups of lung cancer for free low-dose computed tomography (LDCT) screening every 2 years. As of September 19, Within 81 days of implementation, a total of 21 cases of lung cancer were identified, and an average of 1 patient was found every 4 days. Among them, 20 were early-stage patients, but 1 had stage 3 lung cancer. The risk factor was 85.7%. Lung cancer The highest percentage of family history.

Lin Liru, head of the cancer prevention and control team of the National Health Administration, said that from July 1 to September 19, a total of 7,557 people across the country used the program, including 4,200 men and 3,357 women, accounting for 55.6% and 44.4% respectively; Among them, 4470 people, 59.2% had a family history of lung cancer, 2753 people, 36.4% were heavy smokers, and 334 people, 4.4% were heavy smokers with a family history of lung cancer at the same time.

Lin Liru pointed out that in the 81 days of implementation, 21 confirmed lung cancer cases have been identified, of which up to 20 were early (stage 0 and 1) cases, accounting for 95.2%, and only 1 was stage 3 lung cancer, indicating that LDCT lung cancer screening test It is indeed helpful for early diagnosis of lung cancer, and by allowing people to receive treatment as soon as possible, the risk of death from lung cancer can be greatly reduced.

Based on risk factors, among the 21 cases diagnosed with lung cancer, 18, 85.7% had a family history of lung cancer, 2, 9.5% were heavy smokers, and 1, 4.8% were heavy smokers who also had a family history of lung cancer. smoker.

In addition, 11.7% of the people who have been tested for this program have suspected abnormal pulmonary nodules. Although most of the pulmonary nodules are benign, Yang Panchi, an academician of the Chinese Academy of Sciences, reminded that people with suspected abnormal test results must follow the doctor's advice regularly to observe Whether the nodules are new or changed.

National Health Commissioner Wu Zhaojun said that lung cancer ranks the first cause of cancer deaths in Taiwan, accounting for 1/5 of all cancer deaths last year. The main reason is that early stage lung cancer has no obvious symptoms.

According to the 2019 Taiwan Cancer Registry, one out of every two lung cancer cases is stage 4.

However, Wu Zhaojun pointed out that the 5-year survival rate of early stage (0 and 1) lung cancer is more than 90%, but the 4th stage dropped sharply to 10%, the gap is very large, which shows the importance of early screening and has promoted the early detection of lung cancer. Test plan, 2 types of high-risk objects are eligible for use.

Category 2 high-risk subjects include a family history of lung cancer: 50 to 74-year-old men or 45 to 74-year-old women whose parents, children, or siblings have been diagnosed with lung cancer; heavy smoking history: 50 to 74 years of age with a smoking history of up to 30 Pack-year (average number of packs per day * number of years of smoking, such as smoking 1 pack per day for 30 years, or 1.5 packs per day for 20 years, both are 30 pack-years) or more, willing to quit smoking or Heavy smokers who have quit smoking for less than 15 years.
