New therapeutic targets in pancreatic cancer

Pancreatic adenocarcinoma (PDAC) is the most common type of pancreatic cancer (PC) [1 –3]. PDAC incidence is rising; it is expected to become the second cause of cancer-related death by 2030 and has a very poor prognosis[4]. More than 80% of patients have an advanced disease at diagnosis, and the 5-year overall survival rate is approximately 7% [5]. Poor survival is attributed to h igh aggressiveness, intrinsic chemotherapeutics resistance and lack of effectively targetable oncogenic drivers. Systemic chemotherapy is the mainstay of locally advanced (LAPC) and metastatic (MPC) patients treatment and single-agent gemcitabine had been the standard for more than two decades until first-line FOLFIRINOX and nab-paclitaxel/gemcitabine demonstrated better efficacy[6–9].

Conclusion.A significant subset of patients with mPDAC can achieve long‐term survival (≥18 months) in 2018. We identified low NLR as a significant prognostic factor associated with long‐term survival in mPDAC.Implications for Practice.Metastatic pancreatic ductal adenocarcinoma (mPDAC) is one of the most lethal types of cancer. A subset of patients with mPDAC can achieve long‐term survival (≥18 months) with a modern chemotherapy regimen, such as FOLFIRINOX or gemcitabine/nab‐paclitaxel. We identified low neutrophil‐to‐lymphocyte ratio (NLR) as a significant prognostic factor associated with long‐term su...

CONCLUSION: The 'triangle operation' for borderline resectable pancreatic head cancer can be achieved safely by laparoscopy in carefully selected patients.1-11 Proven experience in both open and laparoscopic pancreatic surgery is mandatory. PMID: 31802299 [PubMed - as supplied by publisher]

ConclusionsUnexpected para-aortic lymph node metastasis on frozen section biopsy may no longer be a contraindication to curative resection in “resectable” pancreatic ductal adenocarcinoma, as long as postoperative adjuvant chemotherapy can be administered.

The dismal therapeutic effect is attributed to the chemotherapy resistance and unique pathophysiology with abundant inflammatory cytokines and abnormal hyperplasia of extracellular matrix (ECM). Based on the theory that bone marrow mesenchymal stem cells (BM-MSCs) can influence the...

AbstractThe Japanese guideline for gastroenteropancreatic neuroendocrine tumor treatment recommends everolimus or sunitinib as first-line treatment for unresectable pancreatic neuroendocrine tumors (PNETs). Streptozocin (STZ) is recommended as an alternative. We encountered a patient with PNET who had multiple liver metastases and who showed a remarkable response to third-line STZ. The patient was a 50-year-old man with a pancreatic head tumor 32  mm in diameter. We planned to perform subtotal stomach-preserving pancreaticoduodenectomy, but abandoned resecting the pancreas during the surgery upon discovering a small l...

Wang Rong Hu Resistance to chemotherapy is a major clinical challenge in the treatment of pancreatic ductal adenocarcinoma (PDAC). Here, we provide evidence that Rho associated coiled-coil containing protein kinase 2 (ROCK2) maintains gemcitabine resistance in gemcitabine resistant pancreatic cancer cells (GR cells). Pharmacological inhibition or gene silencing of ROCK2 markedly sensitized GR cells to gemcitabine by suppressing the expression of zinc-finger-enhancer binding protein 1 (ZEB1). Mechanically, ROCK2-induced sp1 phosphorylation at Thr-453 enhanced the ability of sp1 binding to ZEB1 promoter regions in a p...

Introduction: Previous studies show encouraging oncologic outcomes for neoadjuvant chemotherapy (NACT) in the setting of pancreatic ductal adenocarcinoma (PDAC). However, recent literature reported an increased clinical burden in patients undergoing pancreaticoduodenectomy (PD) following NACT. Therefore, the aim of our study was to assess the impact of NACT on postoperative outcomes and recovery after PD.Methods: A retrospective propensity score-matched study was performed including all patients who underwent PD for PDAC in a single center between 2015 and 2018. Patients treated with NACT for resectable, borderline resecta...

VanLathem John R. MacKey Jean-Baptiste Bachet Magali Svrcek Jerome Cros Gemcitabine is still one of the standard chemotherapy regimens for pancreatic ductal adenocarcinoma (PDAC). Gemcitabine uptake into tumor cells is mainly through the human equilibrative nucleoside transport 1 (hENT1). It was therefore proposed as a potential predictive biomarker of gemcitabine efficacy but reports are conflicting, with an important heterogeneity in methods to assess hENT1 expression. A multicenter cohort of 471 patients with a resected PDAC was used to assess simultaneously the predictive value of the 2 best described hENT...
