RT-PCR analysis of the expression of CD44s and its variants in ampullary adenocarcinoma. Fresh samples from six patients with ampullary adenocarcinoma and corresponding normal duodenal tissues were collected from three patients with stage IB cancer (patients 1, 2, and 4) and three patients with stage IIA cancer (patients 3, 5, and 6). Patients 1, 2, and 3 had no disease recurrence while patients 4, 5, and 6 developed recurrence. a HeLa cells served as a positive control. Expression of CD44s, CD44ν3, CD44ν6, CD44ν7, and CD44ν9 was compared between cancer tissue and normal duodenum. The expression patterns were different between patients without recurrence or those with recurrence
