Abstract excerpt

Mutations in the first and second exons of Ha-, Ki- and N-ras oncogenes were investigated in 17 epithelial tumors of the ampulla of Vater by single-strand conformation polymorphism analysis and direct sequencing of DNA fragments amplified by polymerase chain reaction. The panel included 12 intestinal-type adenocarcinomas, 3 villous adenomas, 1 papillary carcinoma and 1 neuroendocrine carcinoma. Six cases (35%)...
