ABSTRACT=
Purpose: The Myc family, especially C-MYC and MYCL1, 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 MYCL1 amplification, L-Myc and c-Myc expression, and investigate clinicopathological characteristics and survival status in patients with surgically resected SCLC.
Methods:MYCL1 amplification was detected using fluorescence in situ hybridization (FISH), while L-Myc and c-Myc protein expressions were determined using immunohistochemistry (IHC) in the primary tumors of 46 resected SCLC patients.
Results: Among the 46 evaluated specimens, MYCL1 amplification was identified in 3/46 cases (6.5%). One of the positive cases was MYCL1 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.
Conclusion: Our study firstly multidimensional explored the expression of MYCL1 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.
