警惕小型肺癌的X线表现

目的:探讨小型肺癌的X线表现。方法:对24例1 cm左右的小型肺癌进行回顾性分析。结果:24例小型肺癌中仅8例诊断及时,引起重视,误诊或漏诊16例。小型肺癌应引起我们的警惕。

90例小型进展型肺癌的外科治疗评价

目的：探讨外科手术为主，辅以化、放疗治疗进展型小肺癌（T1N2M0)的临床效果。方法；分析1986年1月至1996年底行手术治疗的90例进展型小肺癌临床疗效，并将全组中综合治疗42例与单纯手术48例进展型小肺癌效果进行对比。结果：全组1年生存率72．2％，3年生存率28．9％，5年生存率18．9％。单纯手术组5年生存率12．5％；综合治疗组5年生存率26．2％。两组5年生存率之间差异有显著性，P＜0．05，提示综合治疗优于单纯手术。结论：以手术为主的综合治疗可提高进展型小肺癌的远期生存效果。

Detection and Diagnosis of Small Peripheral Lung Cancers Less than 15mm in Diameter

OBJECTIVE To assess the value of chest X-ray film, conventional CT (CCT), Spiral CT (SCT) and high resolution CT (HRCT) for detection and diagnosis of small peripheral lung cancers less than 15 mm in diameter. METHODS Chest X-ray film, CCT, SCT and HRCT were taken in 59 cases of peripheral lung cancers less than 15 mm in diameter confirmed by pathological examination following an operation. The value of these procedures for diagnosis was analyzed retrospectively. RESULTS In 47% of chest X-ray films and 17% of CCT, small lung cancers were not detected. However no tumor escaped detection by SCT. HRCT was superior for showing density and detailed image signs compared to chest films and CCT. The HRCT features of small peripheral lung cancers were quite different from those of larger peripheral lung cancers. CONCLUSION The SCT is the best method for detection, and HRCT for diagnosis of small peripheral lung cancers less than 15 mm in diameter. CT guided percutaneous transthoracic needle biopsy should be advocated.
