The aim: To analyze results of surgical treatment of patients with chronic pancreatitis (CP) and to assess the causes of pancreatic cancer after surgical treatment. Materials and methods: 137 patients had duodenum-preserving resections of the pancreas. Results: In the histological examination of the pancreas it was established that the growth of fibrous tissue was registered in patients with CP., which in 19 (13.8%) almost completely replaced the acinar tissue. In the long term after the operation from 6 months to 2 years in 8 patients (5.8%) pancreatic cancer was detected. Possible causes of tumor origin were analyzed, the value of preservation of ductal hypertension, which affects the state of the duct’s epithelium, was established. The most commonly used for treatment of chronic pancreatitis the Frey surgery removed pancreatic hypertension but in two patients during the operation an insufficient volume of the pancreatic head was reconstructed. In the case of the abandonment of a large array of fibrous tissue, local hypertension was retained in the region of the ductal structures of the head, which led to the transformation of the duct epithelium. An essential factor in the problem of the preservation of pancreatic hypertension were the stenosis of pancreatic intestinal anastomoses, they arose in the long term in 4 operated patients. With stenosis of anastomosis after duodenum-preserving resection both the hypertension factor and the regeneration factor could be realized, which under certain circumstances might be significant. Conclusion: After resection of the pancreas for CP cancer was diagnosed in 5.8% of patients. The main method of preventing the risk of cancer was performing the Frey surgery for CP eliminating pancreatic hypertension in the head region of the pancreas. Diagnosis of stenosis in the late period after resection of the pancreas was an important element in the prevention of recurrence of cancer since a timely reconstructive operation could improve the drainage of duct structures.

Several exosome proteins, miRNAs and KRAS mutations have been investigated in the hope of carrying out the early detection of pancreatic cancer with high sensitivity and specificity, but they have proven to be insufficient. Exosome RNAs, however, have not been extensively evaluated in the diagnosis of pancreatic cancer. The purpose of this study was to investigate the potential of circulating exosome RNAs in pancreatic cancer detection. By retrieving RNA-seq data from publicly accessed databases, differential expression and random-effects meta-analyses were performed. The results showed that pancreatic cancer had a distinct circulating exosome RNA signature in healthy individuals, and that the top 10 candidate exosome RNAs could distinguish patients from healthy individuals with an area under the curve (AUC) of 1.0. Three (HIST2H2AA3, LUZP6 and HLA-DRA) of the 10 genes in exosomes had similar differential patterns to those in tumor tissues based on RNA-seq data. In the validation dataset, the levels of these three genes in exosomes displayed good performance in distinguishing cancer from both chronic pancreatitis (AUC = 0.815) and healthy controls (AUC = 0.8558), whereas a slight difference existed between chronic pancreatitis and healthy controls (AUC = 0.586). Of the three genes, the level of HIST2H2AA3 was positively associated with KRAS status. However, there was no significant difference in the levels of the three genes across the disease stages (stages I–IV). These findings indicate that circulating exosome RNAs have a potential early detection value in pancreatic cancer, and that a distinct exosome RNA signature exists in distinguishing pancreatic cancer from healthy individuals.
