e22155 Background: Insulin-like growth factor receptor-1 (IGFR-1) is a cellular membrane receptor overexpressed in many tumor cell lines and in some human tumors that seems to play a critical role in anti-apoptosis by enhancing cell survival. Also, insulin-like growth factor binding protein-3 (IGFBP-3) was reported to be a growth suppressor in variable pathways. Purpose of this study was to evaluate the state IGFR-1 and IGFBP-3 expression in patients with small cell lung cancer (SCLC) and its prognostic value. Methods: We analyzed IGFR-1 and IGFBP-3 expression in 194 SCLC tissues specimens by immunohistochemical stain. The relationship between IGFR-1 and IGFBP-3 expression and cliniopathological factors was evaluated. Univariate and multivariate analyses were performed to define its prognostic significance. Results: Median age was 63 years (range 38–85), 84% were men. One hundred-seventeen patients had extensive disease (60.3%), and 77 had limited disease (39.7%). With the median follow- up duration of 49.5 months (24–82), the median progression free survival (PFS) and overall survival (OS) were 8 months (95% CI: 7.3–8.7 months), and 14.4 months (95% CI: 12.7–16 months), respectively, The IGFR-1 expression was observed in 154 of 190 tumor tissues (79.4%), whereas there was no tissue stained by IGFBP-3. Multivariate analysis showed that stage (p<0.001), response to treatment (p<0.001), LDH level (p<0.001) were the independent prognostic factors for PFS, and age (p=0.014), LDH level (p<0.001), and stage (p<0.001) for OS. The IGFR-1 positivity was not associated with PFS or OS in the whole cohort. However, 84% of 115 extensive disease patients showed IGFR-1 positivity. The subgroup analysis revealed that OS was significantly longer for patients with IGFR-1 positive compared to those with IGFR-1 negative in extensive disease (11.3% vs 0% at 2year, p=0.034). Conclusions: These results suggest that IGFR-1 expression may be useful as a prognostic marker in patients with extensive disease of SCLC. No significant financial relationships to disclose.
