OBJECTIVETo evaluate the diagnostic value of spirometrically controlled quantitative CT in silica-exposed workers.
METHODSWhole lung spiral scans at 50% vital capacity (VC) and image with high resolution CT(HRCT) at 10% VC and 90% VC level and 5 cm above/below carina were performed in 62 silica-exposed workers and 54 healthy adults. Automatic evaluation software, Pulmo, was used to evaluate the quantitative parameters and compared with clinical pulmonary function tests.
RESULTS9 workers with emphysema were detected by CT scans from 62 silica-exposed workers. The quantitative parameters of 10% VC and 90% VC were significantly different between the silica-exposed workers and the controls (P < 0.05). With the increasing of length of exposure to silica dust, the difference showed a ladder-like rising.
CONCLUSIONSpirometrically controlled quantitative CT is a sensitive, accurate and objective method. It is superior to conventional CT and pulmonary function tests for the early detection in silica-exposed workers, espicially for detecting early stage of small airway disease.

BACKGROUND:
Lung cancer is the leading cause of cancer-related death in China. The results from a randomized controlled trial using annual low-dose computed tomography (LDCT) in specific high-risk groups demonstrated a 20% reduction in lung cancer mortality. The aim of tihs study is to establish the China National lung cancer screening guidelines for clinical practice.
METHODS:
The China lung cancer early detection and treatment expert group (CLCEDTEG) established the China National Lung Cancer Screening Guideline with multidisciplinary representation including 4 thoracic surgeons, 4 thoracic radiologists, 2 medical oncologists, 2 pulmonologists, 2 pathologist, and 2 epidemiologist. Members have engaged in interdisciplinary collaborations regarding lung cancer screening and clinical care of patients with at risk for lung cancer. The expert group reviewed the literature, including screening trials in the United States and Europe and China, and discussed local best clinical practices in the China. A consensus-based guidelines, China National Lung Cancer Screening Guideline (CNLCSG), was recommended by CLCEDTEG appointed by the National Health and Family Planning Commission, based on results of the National Lung Screening Trial, systematic review of evidence related to LDCT screening, and protocol of lung cancer screening program conducted in rural China.
RESULTS:
Annual lung cancer screening with LDCT is recommended for high risk individuals aged 50-74 years who have at least a 20 pack-year smoking history and who currently smoke or have quit within the past five years. Individualized decision making should be conducted before LDCT screening. LDCT screening also represents an opportunity to educate patients as to the health risks of smoking; thus, education should be integrated into the screening process in order to assist smoking cessation.
CONCLUSIONS
A lung cancer screening guideline is recommended for the high-risk population in China. Additional research , including LDCT combined with biomarkers, is needed to optimize the approach to low-dose CT screening in the future.
