Abstract

The restriction fragment length polymorphism of c-Ha-ras-1 and L-myc genes and expression of cell surface effector molecules were studied to determine their potential utility as markers for assessing risk of metastasis in 84 lung cancer patients. We performed a comparative study of primary lung carcinomas, metastases, adjacent tissues and blood samples in a group of patients with lung cancer of different histological types, grade of differentiation and presence of regional and distant metastasis. No differences in the frequency of c-Ha-ras-1 rare alleles were found between lung cancer patients and unaffected controls. The detection of common a4-allele seems to be associated with metastasis and low differentiation of lung carcinomas. S-allele of L-myc was observed in 82.6% of patients with metastatic lesions. Homozygosity of L-allele patients was not evidence for distant metastasis and only 17.4% of these patients have metastatic lesions of the lymph nodes. The expression of HLA class I and receptor of transferrin (TrRec) were tested immunohistochemically in the same patients. In the group of squamous cell carcinomas with regional metastases the expression of HLA class I antigens was decreased [7/21 (33.3%) positive staining tum...Continue Reading
