BACKGROUND: Caveolin-1 plays a regulatory role in several signaling pathways. Recently caveolin-1 was identified as a metastasis-related gene in prostate carcinoma. However, the clinical impact of caveolin-1 expression in esophageal carcinoma remains unknown. METHODS: One hundred thirty surgical specimens of esophageal squamous cell carcinoma were immunohistochemically assessed for caveolin-1 expression by polyclonal antibody. Caveolin-1 immunoreactivity was correlated with patients' clinicopathologic parameters and outcome. RESULTS: Positive caveolin-1 immunostaining was detected in 58 patients (44.6%). Positive caveolin-1 immunostaining correlated positively with pathologic stage (P = 0.029), pN (P = 0.023), and pM (P = 0.018). The overall survival rate was worse in patients with caveolin-1-positive tumors than in patients with caveolin-1-negative tumors (P = 0.0215). Univariate analyses identified caveolin-1 positivity (P = 0.0238), pT (P = 0.0002), pN (P < 0.0001), pM (P = 0.0002), lymphatic invasion (P = 0.0021), and positive surgical margin (P < 0.0001) as negative prognostic predictors. Multivariate analyses indicated that pT (P = 0.0296), pN (P = 0.0003), and a positive surgical margin (P = 0.0452) were independent prognostic factors. CONCLUSIONS: Over-expression of caveolin-1 is associated with lymph node metastasis and a worse prognosis after surgery in esophageal squamous cell carcinoma. Copyright 2002 American Cancer Society.
