支气管癌,特别是末稍支气管癌,早期诊断具有重要意义。因为无症状的末稍支气管癌手术适应性较高,生存率较高,预后较好。但是,此病较难诊断,常误诊为肺结节,术前经病理诊断者只占全部病例的80—85％。作者把病人胸部X线平片的表现转换成数字序列,籍助电子计算机确定某些表现的意义。该研究系根据482名病人的胸部X线平片,全部病人皆经病理诊断,证明为单一肺损害。将这些病人分为三组:①癌组,②良性瘤组, Bronchial cancer, especially the terminal bronchial cancer, early diagnosis is of great significance. Because of asymptomatic distal bronchial surgery more adaptable, higher survival rate, the prognosis is better. However, the disease is more difficult to diagnose, often misdiagnosed as pulmonary nodules, preoperative pathological diagnosis accounted for only 80-85% of all cases. The author converts the performance of a patient’s chest X-ray film into a digital sequence, using electronic computers to determine the significance of some of the manifestations. Based on chest radiographs of 482 patients, all patients were pathologically diagnosed as single lung lesions. These patients were divided into three groups: ① cancer group, ② benign tumor group,
