BACKGROUND: We explored the expression of Fatty Acid Synthase (FAS) in lung carcinomas and its association with clinico-pathological features and prognosis. FAS is a recently discovered molecule involved in the energy supply of normal cells. FAS is also overexpressed in neoplastic tissues because of their increased necessity for energy. PATIENTS AND METHODS: One hundred and six patients with non-small cell lung carcinoma were followed-up for an average period of 5 years. FAS expression was detected immunohistochemically. RESULTS: FAS staining was observed in 61 out of 106 cases (57.54%). Statistical analysis revealed that FAS had an overall low prognostic value (p = 0.14), while FAS-negative expression in stage I patients showed a trend for better survival (p = 0.10). PTNM stage (p < 0.0001) was the only significant prognostic marker for overall survival. CONCLUSION: FAS is a reliable marker of low-stage clinically aggressive lung carcinomas. The determination of FAS expression in lung carcinomas may stratify patients and determine therapeutic approaches for their care.
