Abstract

The SDF-1/CXCR4 axis is associated with tumor progression and has been reported as a prognostic parameter, although with conflicting data for non-small cell lung cancer (NSCLC). This study examines a large cohort of clinically and pathologically well-characterized NSCLC patients and includes the activated form of CXCR4 (pCXCR4), which has not been studied in this context so far. SDF-1, CXCR4, and pCXCR4 were assessed immunohistochemically in 371 surgically resected NSCLC using a standardized tissue microarray platform. Extensive clinical and pathological data and a postoperative follow-up period of 17 years enabled detailed correlations. CXCR4 and pCXCR4 were frequently expressed on squamous cell carcinoma. Membranous expression of SDF-1 was a marker of poor prognosis and proved to be an independent prognostic parameter for the entire cohort and for patients with adenocarcinoma (ACA) and large cell carcinoma (LCC). Targeted cancer therapies blocking SDF-1/CXCR4 interaction already exist, and our data suggest that expression of SDF-1, especially on poorer prognosis subgroups of LCC and ACA, indicates patients that might benefit more than others. This should be taken into account when assessing the effectiveness of such targeted ...Continue Reading
