OBJECTIVE Detecting the loss of heterozygosity in paraffin-embedded pancreatic cancer tissues. METHODS Analysing loss of heterzygosity (LOH) of microsatellite DNA on chromosome loci 3,5,7,9 and 18 with PCR-SSLP-silver stain method in pancreatic cancer. RESULTS In 45 sporadic pancreatic cancer samples and their paired control tissue, LOH was detected on site for D18S46( 18q21.1,31.0%), D18S474 (18q21.1, 20.0%), D9S176 (9q22-31,20.0%), D3S1234 (3p14.2,17.5%),D 3S1289 (3p21.1, 15.7%), D3S1481 (3p14.2,4.9%), D7S486 (7q22,3.6%), D5S365 (5q32, 3.2%) and D3S587 (3p24-26, 2.6%). CONCLUSIONS Different percentages of loss of heterzygosity on specific chromosomal regions were found, and the meaning of the results was discussed. Some key genes may play a role in the pathogenesis of pancreatic cancer.

D010190 Pancreatic Neoplasms Tumors or cancer of the PANCREAS. Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).
