CHD1L and non-small cell lung carcinoma: Since amplification of 1q, in which the CHD1L gene is located, was frequently examined in NSCLC and correlated closely with tumor recurrence and metastasis [13, 14], we conducted this study to examine the expression and amplification dynamics of CHD1L in a large cohort of NSCLC patients, and its clinicopathologic and prognostic significance was further evaluated.
