The distinction of intrapulmonary metastases from multiple primaru tumors is of great clinical importance as it influences staging, prognosis and therapeutic strategy. Although Comprehensive Assessment (CHA) was recommended by IASLC/ATS/ERS to differentiate multiple lung primary non-small cell carcinoma from metastases, the limitaitons of CHA have been addressed. Lung adeocarcinoma in situ is characteried by noninasive lepidic growth. Whether this histological characterized by noninvasive lepidic growth. Whether this histological characteristic could be served for assessing primary lung cancer has not been well determined. In this study, we evaluated the applicaion value of CHA and lepidic growth component (LGC) in ditinguishing multiple primary lung cancers from intrapulmonary metastass.
