Pancreatic cancer (PC) is a leading cause of cancer death worldwide, especially in Western societies. Its aggressive nature and poor prognosis increase the need for identifying new and more accurate diagnostic and prognostic tools. We studied 41 patients who had undergone radical surgical resection for PC, investigated B7H4 protein expression in the PC tissue specimens of these patients by immunohistochemistry and analyzed several clinical and pathological features. The positive expression of the B7H4 antigen was associated with a negative impact of chemotherapy with gemcitabine on patient survival and also correlated with high CA19.9 serum levels and poorly differentiated tumors. Moreover, patients that overexpressed B7H4 antigen had worse prognosis compared to the ones that did not overexpress B7H4. B7H4 antigen is a negative prognostic marker for PC patients and also seems to express resistance of PC patients to chemotherapy with gemcitabine. © 2015 Springer-Verlag Italia

OBJECTIVES: The postoperative morbidity after pancreatectomy remains high. The role of somatostatin and its analogs in reducing complications after pancreatic resection is controversial. The aim of the study was to evaluate the ability of somatostatin to influence pancreatic cell's function with consequence the decrease of postoperative complications. METHODS: Between January 2006 and December 2009, 67 patients for which pancreatectomy was indicated were randomized into 2 groups. At surgery, biopsies of the pancreas were taken to be studied by electron microscopy and analyzed for ultrastructural morphometry. RESULTS: The total mortality was 4.4% (n = 3/67; 2 patients from the control group and 1 patient from the treatment group). The overall morbidity was 35.8% (n = 24/67). Eighteen patients in the control group (n = 18/32; 56.25%) and 6 patients in the treatment group (n = 6/35; 17.14%) developed postoperative complications (2-tailed Fisher exact test; P = 0.001). The most common complication was the presence of fistula (n = 6/67; 8.95%). CONCLUSIONS: Perioperative administration of intravenous somatostatin at rates applied in this study was able to inhibit the exocrine pancreatic function. This finding supports the prophylactic effect of somatostatin on the early postoperative complications of pancreatic surgery shown in this study. Copyright © 2012 by Lippincott Williams & Wilkins.

Objectives: Pancreatic cancer (PC) is one of the most lethal tumors of the gastrointestinal tract. The ability to predict which patients would benefit most from surgical intervention and chemotherapy would be a great clinical tool. A large number of potential markers have been identified lately in pancreatic cancer and their clinical utilities as prognostic tools are under investigation. Methods: We recruited 41 patients who had undergone radical surgical resection for PC between 2003 and 2010. To investigate the prognostic factors, we evaluated 3 possible markers: B7H4, HSP27 and DJ-1 protein expressions in the tissue specimens of these 41 patients by immunohistochemistry and analyzed the clinical and pathological features of these specimens. Results: The expression of the three antigens was independently associated with a negative impact of chemotherapy with gemcitabine on patient's survival. Moreover, patients who overexpressed B7H4 had worse prognosis than the ones who did not. Conclusions: B7H4, DJ-1 and HSP27 may be used in the future as prognostic markers that express resistance of pancreatic cancer patients to chemotherapy with gemcitabine.
