Special Issue Information

Dear Colleagues,

Recent advances in cancer treatment research and development, especially the development of immune checkpoint inhibitors, have dramatically increased the life expectancy of patients diagnosed with cancer over the past decade. In addition, advances in comprehensive genetic analysis have made it possible to analyze abnormalities in driver genes that are important for the growth of cancer, and the development of specific therapeutic agents for such abnormalities has also progressed. Even under such circumstances, pancreatic cancer has not benefited from new therapeutic agents, with little improvement in prognosis. Why does pancreatic cancer have a worse prognosis than other cancer types? Why are new therapeutic agents developed that do not work for pancreatic cancer? In order to solve these questions, this Special Issue explores the mechanisms that are unique to pancreatic cancer and aims to lead the development of novel therapeutic agents that can overcome these problems.

Abstract
Background: According to current guidelines, preoperative endoscopic retrograde cholangiopancreatography (ERCP) with biliary stenting (ERCP/stenting) is often necessary in patients with obstructive jaundice due to pancreatic ductal adenocarcinoma (PDAC), including severe jaundice (bilirubin > 250 umol/l), pruritus, cholangitis, cholestatic liver dysfunction, renal failure, severe [...] Read more.
Background: According to current guidelines, preoperative endoscopic retrograde cholangiopancreatography (ERCP) with biliary stenting (ERCP/stenting) is often necessary in patients with obstructive jaundice due to pancreatic ductal adenocarcinoma (PDAC), including severe jaundice (bilirubin > 250 umol/l), pruritus, cholangitis, cholestatic liver dysfunction, renal failure, severe malnutrition, or delayed surgery for tumors requiring neoadjuvant chemotherapy. We aimed to investigate the impact of preoperative ERCP/stenting on postoperative and long-term outcomes following pancreaticoduodenectomy (PD) for PDAC. Methods: Clinicopathological data of patients who underwent partial/total PD for PDAC between 2012 and 2019 in two hepato-pancreato-biliary centers in Germany and Switzerland were assessed. We compared patients treated with preoperative ERCP/stenting with those directly undergoing surgery according to postoperative morbidity, postoperative mortality, overall survival (OS) and disease-free survival (DFS). Results: During the study period, 192 patients underwent partial/total PD for PDAC. ERCP/stenting was performed in 105 patients, and 87 patients underwent resection without prior intervention. Postoperative 90-day overall morbidity rate (71% vs. 56%, p = 0.029) and superficial surgical site infection (SSI) rate (39% vs. 17%, p < 0.001) were significantly worse following preoperative ERCP/stenting. Major postoperative morbidity rate (18% vs. 21%, p = 0.650), organ/space SSI rate (7% vs. 14%, p = 0.100), and 90-day postoperative mortality rate (4% vs. 2%, p = 0.549) did not significantly differ between the two groups. After excluding 44 patients for whom the indication for ERCP/stenting was not consistent with current guidelines, ERCP/stenting was associated with a higher superficial SSI rate (36% vs. 17%, p = 0.009) and shorter length of stay (12 vs. 16 days, p = 0.004). Median OS (ERCP/stenting: 18 months vs. no ERCP/stenting: 23 months, p = 0.490) and median DFS (ERCP/stenting: 14 months vs. no ERCP/stenting: 18 months, p = 0.645) were independent from the utilization of ERCP/stenting. Conclusions: Preoperative ERCP/stenting in patients with PDAC can be performed without increasing organ/space SSI, major perioperative morbidity, and mortality rates and without worsening oncologic outcomes. However, it is associated with higher superficial SSI rates. If ERCP/stenting is not performed routinely but according to current guidelines, it is also associated with a shorter length of hospital stay. Further refinement of the indications for preoperative ERCP/stenting may reduce superficial SSI rates. Full article

Patients with pancreatic neuroendocrine tumors (pNETs) have limited access to effective targeted agents and invariably succumb to progressive disease. MUC1-C is a druggable oncogenic protein linked to driving pan-cancers. There is no known involvement of MUC1-C in pNET progression. The present work was performed to determine if MUC1-C represents a potential target for advancing pNET treatment. We demonstrate that the MUC1 gene is upregulated in primary pNETs that progress with metastatic disease. In pNET cells, MUC1-C drives E2F- and MYC-signaling pathways necessary for survival. Targeting MUC1-C genetically and pharmacologically also inhibits self-renewal capacity and tumorigenicity. Studies of primary pNET tissues further demonstrate that MUC1-C expression is associated with (i) an advanced NET grade and pathological stage, (ii) metastatic disease, and (iii) decreased disease-free survival. These findings demonstrate that MUC1-C is necessary for pNET progression and is a novel target for treating these rare cancers with anti-MUC1-C agents under clinical development. Full article

Objectives: Autoimmune pancreatitis (AIP) type 1, paraduodenal (groove) pancreatitis, and follicular pancreatitis are rare clinical entities whose diagnosis may be challenging, given the potential imaging overlap with pancreatic cancer. Methods: We performed a retrospective analysis of the medical chart of a patient with multiple pancreas pathologies. Results: We present a case with multiple pancreas pathologies, including a poorly differentiated ductal adenocarcinoma of pancreatobiliary type, an intraductal papillary mucinous lesion (pre-existing lesion of IPMN type), and an inflammatory process with complex features, in which paraduodenal (groove) pancreatitis, follicular pancreatitis, and IgG4-related pancreatitis (AIP type 1) were also present. Conclusions: The diagnosis of AIP and paraduodenal pancreatitis is not always straightforward, and in some cases, it is not easy to differentiate them from pancreatic cancer. Surgery should be considered in patients when a suspicion of malignant/premalignant lesions cannot be excluded after a complete diagnostic work-up. Full article
