[Cell oncogene expression in human stomach tumors].

The paper is concerned with the analysis of expression of myc, myb, fos, ras and sis oncogenes in 11 gastric tumors of different histological patterns, 5 histologically-unaltered areas adjacent to tumor and in stomach tumor metastases into lymph nodes. A high frequency of myc, ras and fos oncogene expression was registered in all the types of tissue examined without any apparent signs of tissue specificity. The study failed to detect sis oncogene transcripts. The myb oncogene, generally dormant in solid tumors, was expressed in 2 gastric tumor metastases.
