The Myc family, especially and , has been found involved in small-cell lung carcinoma (SCLC). Identification of the frequency of C-MYC and MYCL1 expression among SCLC patients may help to identify potential targets for therapeutic intervention. Our aim was to detect amplification, L-Myc and c-Myc expression, and investigate clinicopathological characteristics and survival status in patients with surgically resected SCLC. amplification was detected using fluorescence hybridization (FISH), while L-Myc and c-Myc protein expressions were determined using immunohistochemistry (IHC) in the primary tumors of 46 resected SCLC patients. Among the 46 evaluated specimens, amplification was identified in 3/46 cases (6.5%). One of the positive cases was gene amplification combined with fusion. 3/46 (6.5%) was positive for L-myc protein expression, and 4/46 (8.7%) was positive for c-Myc protein expression. Our study firstly multidimensional explored the expression of amplification, L-Myc and c-Myc protein and investigated clinicopathological characteristics and survival status in patients with surgically resected SCLC, which makes a contribution to subsequent research and therapeutic strategies.
