The survival from bronchogenic carcinoma is highly dependent upon stage at the time of treatment. This is particularly true for squamous cell carcinoma, adenocarcinoma, and large cell carcinoma, but holds true for small cell carcinoma as well. The problem presented to the medical profession has been to find a practical means of detecting lung cancer while it is still at an early stage. Three studies in progress have indicated that a larger proportion of the patients may be found to have early stage lung cancer when screened with a combination of chest X-rays and sputum cytology. However, the detection of these early stage cases has not yet been translated into an improvement in the overall mortality rate from lung cancer.
支气管源性癌的生存率高度依赖于治疗时的分期。对于鳞状细胞癌、腺癌和大细胞癌尤其如此，对于小细胞癌也同样适用。医学界面临的问题一直是找到一种切实可行的方法，在肺癌仍处于早期阶段时进行检测。三项正在进行的研究表明，当采用胸部X光和痰细胞学检查相结合的方法进行筛查时，可能会发现更大比例的患者患有早期肺癌。然而，这些早期病例的发现尚未转化为肺癌总体死亡率的改善。
