自从1950年Overholt提出团检对肺癌的早期诊断和早期治疗具有实用价值以来,至今有较多的报告。国内外一致认为肺癌发病有逐渐增加趋势,并且肺癌的死亡率较高。但有报告指出,早期发现早期治疗的肺癌病人五年存活率可达到80%。甚至有的报告指出,中心型早期肺癌的五年存活率接近100%。可见如何做到早期发现肺癌病人仍是个关键问题。如何评价团检在发现肺癌方面的作用尚有争议,美国认为团检不仅花费较大,而且
Since Overholt proposed in 1950 that group inspection has practical value for the early diagnosis and early treatment of lung cancer, there have been more reports so far. At home and abroad, it is agreed that there is a gradual increase in the incidence of lung cancer, and the mortality rate of lung cancer is higher. However, there are reports that early detection of early treatment of lung cancer patients can reach 80% five-year survival rate. Even some reports indicate that the five-year survival rate of central early-stage lung cancer is close to 100%. It can be seen how early detection of lung cancer patients is still a key issue. How to evaluate the role of group inspection in the detection of lung cancer is controversial. The United States believes that the group inspection is not only costly but also
