The United States Preventative Services Task Force recommendation (most recently updated in 2004) is that the evidence is insufficient to recommend for or against screening asymptomatic persons for lung cancer with LD-CT, CXR, sputum cytology; or a combination of these tests.
A Cochrane review (1) identified 6 randomized controlled trials (RCTs) and 1 non-RCT (with a total of 245,610 patients) that screened patients with serial chest x-rays, with or without sputum cytology. Most patients were current or ex-smokers or had significant exposure to industrial smoke.
Sputum cytology is now, however, less commonly used, as fibreoptic bronchoscopy has become more widely available and is known to give a high diagnostic yield [3].

Low-dose, helical CT scans of the lung have greater sensitivity in diagnosing lung cancer than do chest x-ray and sputum cytology, which have not been shown to reduce lung cancer mortality significantly in screening studies, she said.
Even with the addition of sputum cytology and more frequent chest x-rays, lung cancer mortality was unchanged (SOR: A).
To our knowledge, the current study is the first to investigate HA as an indicator in the sputum from patients with LC, therefore limiting a comparison of the results, unless they are compared to the current gold standard, sputum cytology. Presently, sputum cytology is the minimum invasive resource for obtaining a diagnosis in a patient who is suspected of having LC.
Patient who did not improve clinically or worsened during the treatment were subjected to repeat chest X-ray in the second week of treatment and patient showing less than 50% resolution on chest X ray after receiving 10-14 days of antibiotics were included in the study and were investigated thoroughly-repeat sputum C/S, sputum AFB, mantoux test, sputum cytology, ELISA-HIV and in a few cases fungal studies, CT-scan, Bronchoscopy were advised.
A variety of tools is available for this purpose, including transthoracic needle aspiration (TTNA), standard bronchoscopy, sputum cytology, and surgical biopsy.
