内镜诊断隐性肺癌（附45例分析）

天津市肿瘤医院经7150次纤维支气管镜检出X线平片隐性肺癌41例,X线与内镜双隐性肺癌4例。中位年龄各为56岁及63岁,男性为主。X线隐性癌分布于Ⅰ~Ⅱ级气道,隆突和气管,后者占60%,包括双侧病灶而一侧X线隐性。早期癌含原位癌约占25%。文章分析了各类隐性癌的表现及分期情况;指出X线隐性癌病理分期及浸润程度的混杂性。本文评价了普通X线片、断层及CT、NMR在诊断隐性肺癌中的特点,提出因部位不同而适当选择不同的方法;强调支气管镜在早期诊断中的重要作用,指出确诊双隐性肺癌须多部位重复取材活检可有裨益。

Fiberscopic Diagnosis in Lung Cancer. A Report of 45 Cases

Forty five cases of occult lung cancer (OLC) diagnosed by bron-chofiberscopy and pathologic examination were reported out of 7150 examinations. Forty one cases weren' t detected by X-ray, by bronchofiberscopy and 4 cases weren' t discovered by the above two methods until cytological diagnosis was made. In this series, 25% were early stage lung cancer. In patients as seen here ordinary X-ray examination and tomography often gave negative results. CT and NMR were more effective and bronchofiberscopy was most efficacious in the detection of OLC. Repeated fiberscopic examinations and biopsies at different suspicious sites would increase the detective rate.
