Summary: | Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKI) as gefitinib emerged as an accepted treatment in second- or third-line setting in NSCLC. However, clinical surrogate markers of EGFR-TKI activity in NSCLC patients remain to be identified and we studied the prognostic value of CYFRA 21-1 in this setting. Serum samples from 53 patients with NSCLC receiving gefitinib after failure of at least a platinum-containing regimen were prospectively collected from January 2002 to December 2003. Multivariate analysis demonstrated an independent negative impact on survival for a level of CYFRA 21-1 higher than 3.5 ng ml(-1) (HR=2.45, 95% CI 1.13-5.29; P=0.02). In conclusion, CYFRA 21-1 is a tool available to predict the survival of NSCLC patients receiving gefitinib as third-line therapy in an independent manner. In case of a CYFRA 21-1 level higher than 3.5 ng ml(-1), treatment with gefitinib needs further evaluation giving its relative poor effect on survival. |
