In the current study, 263 primary nonsmall cell lung cancers were investigated for the expressions of Fhit and p53 by immunohistochemistry. Marked reduction of Fhit immunoreactivity (< 10% positivity) in 156 (59%) tumours and overexpression of p53 protein (> 10% positivity) in 89 (34%) tumours were found. Reduced Fhit expression was also noted in most squamous cell carcinomas (80 out of 99, 81%), and in a smaller fraction of adenocarcinomas (76 out of 164, 46%; P < 0.001). p53 nuclear staining was demonstrated in 54 out of 99 (55%) squamous cell carcinomas and in 35 out of 164 (21%) adenocarcinomas (P < 0.001). The loss of Fhit expression and p53 overexpression was significantly more common in tumours occurring in smokers (93 out of 113, 82% and 56 out of 113, 50%) than in those of nonsmokers (63 out of 150, 42%; P < 0.001 and 33 out of 150, 22%; P < 0.001). Notably, p53 overexpression was associated with distant metastasis of patients in the whole series (P = 0.027) and in adenocarcinoma (P = 0.001). It was also associated with a poorer survival of patients with adenocarcinoma (P = 0.032). ? 2003 Cancer Research UK. |
