Neoadjuvant Stereotactic Body Radiotherapy After Upfront Chemotherapy Improves Pathologic Outcomes Compared With Chemotherapy Alone for Patients With Borderline Resectable or Locally Advanced Pancreatic Adenocarcinoma Without Increasing Perioperative Toxicity
Background Patients with borderline resectable pancreatic cancer (BRPC) or locally advanced pancreatic cancer (LAPC) are at high risk of margin-positive resection. Neoadjuvant stereotactic body radiation therapy (SBRT) may help sterilize margins, but its additive benefit beyond neoadjuvant chemotherapy (nCT) is unclear. The authors report long-term outcomes for BRPC/LAPC patients explored after treatment with either nCT alone or nCT followed by five-fraction SBRT (nCT-SBRT). Methods Patients with BRPC or LAPC from 2011 to 2016 who underwent resection after nCT alone or nCT-SBRT [...]
It is the lymph node ratio that determines survival and recurrence patterns in resected distal cholangiocarcinoma. A multicenter international study
Background Distal cholangiocarcinoma (dCC) is still associated with a poor overall survival (OS). This study aims to investigate the impact of novel prognostic scores in comparison with more traditional ones. Methods Multicentric retrospective analysis of patients who underwent a pancreatoduodenectomy (PD) for dCC. An unadjusted analysis was used to identify predictors of decreased survival. Significant variables were introduced in a multivariable model that assessed OS, recurrence-free survival (RFS), early recurrence (defined as a recurrence within the first 12 months from the PD), local and [...]
Concomitant splenic artery ligation has no preventive effect on left-sided portal hypertension following pancreaticoduodenectomy with the resection of the portal and superior mesenteric vein confluence for pancreatic ductal adenocarcinoma
Background: Left-sided portal hypertension (LSPH) caused by splenic vein (SV) division in pancreaticoduodenectomy (PD) with portal vein (PV) resection remains challenging. The current study aimed to investigate the efficacy of splenic artery (SA) ligation in preventing LSPH. Methods: One-hundred thirty patients who underwent PD with PV resection for pancreatic ductal adenocarcinoma were classified into SV and SA preservation (SVP, n = 30), SV resection and SA preservation (SVR, n = 59), and SV resection and SA ligation (SAL, n = [...]
Extensive (subtotal) distal pancreatectomy for pancreatic ductal adenocarcinoma: a propensity score matched cohort study of short- and long-term outcomes compared with those of conventional distal pancreatectomy
Purpose Extensive distal pancreatectomy (ExDP) can transect the pancreatic parenchyma more from the right side than conventional distal pancreatectomy (CDP) can. This study aimed to evaluate the short- and long-term outcomes of ExDP for pancreatic ductal adenocarcinoma (PDAC) of the pancreatic body, located adjacent to the portal vein (PV). Methods Medical records of 98 patients who underwent ExDP (n = 15) or CDP (n = 83) for PDAC were retrospectively reviewed. Short- and long-term outcomes of the two groups were compared. Propensity score matched [...]
Pancreatic ductal adenocarcinoma: Prognostic indicators of advanced disease
Background/Objectives Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy associated with high metastatic risk. Prognosis remains poor even after resection. Previously our group identified biomarkers that improved diagnostic accuracy in PDAC beyond the established diagnostic tumour marker, CA19-9. Risk factors, symptoms and circulating biomarkers associated with a PDAC diagnosis may differ from those that alter disease progression and metastasis. This study aimed at assessing the risk factors, presenting symptoms and potential prognostic biomarkers in PDAC and determine their relationship with [...]
Robotic versus open pancreaticoduodenectomy with vascular resection for pancreatic ductal adenocarcinoma: surgical and oncological outcomes from pilot experience
Purpose Venous resection and reconstruction (VR) is a feasible surgical technique to achieve optimal outcomes in selected patients with pancreatic ductal adenocarcinoma (PDAC) who undergo open pancreaticoduodenectomy (OPD). However, data regarding patient outcomes in patients who undergo VR in robotic-assisted pancreaticoduodenectomy (RPD) are scarce. Methods All patients with a diagnosis of PDAC who underwent upfront open or robotic pancreatoduodenectomy with VR in a high-volume institution for pancreatic surgery between 2011 and 2019 were retrospectively reviewed. Perioperative and long-term outcomes were [...]
