Background: The aim of this study is to investigate the expressions of somatostatin receptor (SSTR), SSTR-2, SSTR-3, and SSTR-5, in pancreatic tissue and non-cancerous tissue and elucidate their clinical significance. Methods: The expression of somatostatin receptor subtypes SSTR-2, SSTR-3, and SSTR-5 messenger RNA (mRNA) in 108 cases of cancer tissue and adjacent tissue in patients with pancreatic cancer was detected by reverse transcriptase polymerase chain reaction (RT-PCR). Expression of SSTR-2, SSTR-3, and SSTR-5 mRNA was evaluated after specimens were taken from selected patients who underwent surgical resection by Whipple's operation. We speculated the clinical significance of the expression of somatostatin receptor (SSTR) subtype genes SSTR-2, SSTR-3, and SSTR-5 in pancreatic tissue and non-cancerous tissue and further elucidated their clinical significance. Results: The expression rates of SSTR-2 mRNA in cancer and adjacent tissue of 108 patients with pancreatic cancer were 81.5% (88/108) and 97.2% (105/108), respectively; SSTR-3 mRNA expression rates were 69.4% (75/108) and 55.6% (60/108). SSTR-5 mRNA expression rates were 13.0% (14/108) and 18.5% (20/108). Conclusion: We propose that SSTR-2 plays an important role in clinical implications for patients with pancreatic cancer undergoing somatostatin or its analog therapy.
