Patients with pulmonary tuberculosis treated in 4 sanatoria in Niigata prefecture during the period from 1941 to 1961 were followed up. Of 2,756 patients, 1,193 responded and sent us effective information. However, 1,224 did not come into contact because of changed and unknown adress, 326 did not respond, and 13 were omitted because of incomplete answers. Of 1,193 effective responders, 568 had been treated by artificial pneumothorax (the pneumothorax group), and 552 had been treated by the other measures than pneumothorax (the control group). There were 65 deaths in the pneumothorax, group, and 40 deaths in the control group. No deaths from chest malignancies were reported in the pneumothorax group, while 4 chest malignancies in the control. In this survey, no evidence of increased frequency of chest malignancies including leukemia following multiple fluoroscopies during artificial pneumothorax was detected.
对1941年至1961年期间在新潟县4家疗养院接受治疗的肺结核患者进行了随访。在2756名患者中，1193名做出了回应并向我们提供了有效信息。然而，1224名患者因地址变更或地址不明而失去联系，326名患者未做出回应，13名患者因回答不完整而被排除。在1193名有效回应者中，568名接受了人工气胸治疗（气胸组），552名接受了除气胸以外的其他治疗措施（对照组）。气胸组有65人死亡，对照组有40人死亡。气胸组未报告有死于胸部恶性肿瘤的病例，而对照组有4例胸部恶性肿瘤。在本次调查中，未发现人工气胸期间多次透视后包括白血病在内的胸部恶性肿瘤发生率增加的证据。
