| Outline of Final Research Achievements |
We analyzed LCNEC gene expression, gene mutation and immunohistochemical expression of known molecular targets and compared expression to that of lung adenocarcinomas. We analyzed 26 patients with primary LCNEC and 40 patients with adenocarcinoma (AC). We evaluated immunohistochemical (IHC) expression for topoisomerase I, II (TOPO1, 2), excision repair cross-complementing gene 1 (ERCC1), class III beta tubulin (TUBB3) and EGFR mutation (L858R) and gene mutation for EGFR using direct DNA sequencing and Scorpion-ARMS. There was a significant difference in IHC expression for TOPO2 and EGFR between LCNEC and AC. EGFR gene mutation was greater in the AC group, with no EGFR mutation in the LCNEC group. On the IHC expression of TOPO1, ERCC1, and TUBB3, there were no significant differences between LCNEC and AC.
