肺癌的早期诊断、早期治疗是提高肺癌患者生存率和治愈率的关键。据文献报道,瘤体直径小于3cm者,其五年生存率为42.9％,而大于5cm者仅为16.1％。目前对小肺癌的发现无论是中心型或周围型,X线检查仍为首选方法。但由于小肺癌缺乏特征性X线表现,定性诊断较为困难,本文选择了我院经手术及病理证实的11例2cm以下的周围型小肺癌,作为探讨对象。对小肺癌的X线征象和检查方法加以分析。
The early diagnosis and early treatment of lung cancer is the key to improve the survival rate and cure rate of lung cancer patients. According to reports in the literature, the five-year survival rate of the tumor with a diameter of less than 3cm is 42.9%, and only 16.1% is greater than 5cm. At present, the discovery of small lung cancer, whether central or peripheral, is still the preferred method for X-ray examination. However, due to the lack of characteristic X-ray findings of small lung cancer, qualitative diagnosis is more difficult. This article selected 11 cases of small peripheral lung cancer below 2cm in our hospital as confirmed by surgery and pathology. X-ray signs and examination methods for small lung cancer were analyzed.
