Further investigations of the study group for the early detection of lung cancer in the GDR have confirmed previous conclusions that annual x-ray screening of the chest significantly improves the results of surgical treatment of cancer of the lung. The study now covers 15,336 cases operated upon between 1949 and 1976. Two thirds of all cases treated surgically in the period from 1963 to 1972 were detected by roentgenologic screening. In the screening group the 5-year survival rates after resection were more favourable than in the clinical group: 36% in 1,915 screening cases and 29% in 785 clinical cases in the period from 1965 to 1968. The percentage of peripheral lesions which were treated by lobectomy was significantly higher in the screening group. Since the introduction of a biannual mode of screening, the overall results have worsened because the number of cases detected by x-ray screening has decreased.
德意志民主共和国肺癌早期检测研究组的进一步调查证实了先前的结论，即每年进行胸部X光筛查可显著改善肺癌手术治疗的效果。该研究目前涵盖了1949年至1976年间接受手术的15336例病例。在1963年至1972年期间接受手术治疗的所有病例中，三分之二是通过放射学筛查发现的。在筛查组中，切除术后的5年生存率比临床组更有利：在1965年至1968年期间，1915例筛查病例中的生存率为36%，785例临床病例中的生存率为29%。在筛查组中，通过肺叶切除术治疗的周围性病变的百分比显著更高。自从采用半年一次的筛查模式以来，总体结果有所恶化，因为通过X光筛查发现的病例数量减少了。
