OBJECTIVE: To evaluate prognostic impact of maspin expression in patients with resected non-small cell lung cancer (NSCLC). STUDY DESIGN: From 1996 to 2001, 439 patients underwent radical surgery for NSCLC at the Polytechnic University of the Marche Region. Maspin expression was detected as cytoplasmic and nuclear staining of neoplastic cells. For cytoplasmic staining, cases were classified as negative, low positive, and high positive. In positive cases, intensity of staining was also considered and scored. A similar classification was used for nuclear staining, but intensity was not considered. RESULTS: The analysis showed that smoking history, pathologic stage of disease, N status, histologic grading, sex, and Eastern Cooperative Oncology Group performance status had a prognostic impact on overall survival (OS). Expression of maspin was also found to be an independent prognostic factor. A statistically significant longer OS was seen in patients with higher compared with lower expression of nuclear maspin, and poorer OS was present in patients with a higher intensity of cytoplasmic staining. Nuclear expression of maspin was also found to be an independent prognostic factor at multivariate analysis. CONCLUSION: Results suggest that overexpression of maspin correlates with favorable prognosis in NSCLC. and may be a useful clinical marker.
