为探讨胸部X线诊断早期发现肺癌的可靠性,以北海道大学医学院第一内科1967—76年10年间174名住院肺癌病人为研究对象,其中包括经集体检诊发现异常的54例(31.0％)。 X线胸片检查结果如下:1.174例中有71例(40.9％)开始时诊断不正确,其中57例为Ⅱ期和Ⅲ期肺癌,占71例的80.3％。 2.经集体检诊X线胸片发现异常的54例中仍有15例误诊,占27.8％。确诊后,其中的53.3％已是Ⅱ期或Ⅲ期。集体检诊时,此54例中,28例(51.9％)完全没有自觉症状。
To investigate the reliability of early detection of lung cancer by chest X-ray diagnosis, 174 hospitalized lung cancer patients in the first Department of Internal Medicine of Hokkaido University School of Medicine during the period of 1967-76 were studied, including 54 cases (31.0%) found to be abnormal by the group examination. ). The X-ray findings were as follows: 71.74 cases (40.9%) were diagnosed incorrectly at the beginning, and 57 cases were stage II and stage III lung cancer, accounting for 80.3% of 71 cases. 2. Of the 54 cases with abnormal X-ray findings on the collective examination, 15 cases were misdiagnosed, accounting for 27.8%. After diagnosis, 53.3% of them were already in phase II or phase III. At the time of the collective examination, of the 54 patients, 28 (51.9%) had no symptoms at all.
