The FHIT/GAPDH mRNA level was less in squamous cell carcinoma (0.144 +/- 0.246), a smoking-related cancer, than in adenocarcinoma (0.72 +/- 1.321.     ///    n = 57) was significantly worse than in the patients with high FHIT/GAPDH levels (> 0.26.     ///    "No significant difference in FHIT/GAPDH mRNA levels was found among age, T status, or lymph node metastasis. "    ///    The FHIT/glyceraldehyde-3-phosphate dehydrogenase (GAPDH) mRNA levels were decreased in tumor tissues from lung cancer (13.844 +/- 33.047) compared with adjacent nonmalignant lung tissues (195.763 +/- 678.469.     ///    The prognosis for patients with lung cancer with low FHIT/GAPDH levels (< 0.26.     ///    FHIT/GAPDH mRNA levels were correlated with FHIT protein (P = 0.0139) and p21 protein (P = 0.0484) expression by immunohistochemistry.
