Aggressive arterial resection (AR) or total pancreatectomy (TP) in surgical treatment for locally advanced pancreatic cancer (LAPC) had long been discouraged because of their high mortality rate and unsatisfactory long-term outcomes. Recently, new chemotherapy regimens such as FOLFIRINOX or Gemcitabine and nab-paclitaxel have provided more adequate patient selection and local tumor suppression, justifying aggressive local resection. In this review, we investigate the recent reports focusing on arterial resection and total pancreatectomy for LAPC and discuss the rationale of such an aggressive approach in the treatment of PC. AR for LAPCs is divided into three, according to the target vessel. The hepatic artery resection is the simplest one, and the reconstruction methods comprise end-to-end, graft or transposition, and no reconstruction. Celiac axis resection is mainly done with distal pancreatectomy, which allows collateral arterial supply to the liver via the pancreas head. Resection of the superior mesenteric artery is increasingly reported, though its rationale is still controversial. Total pancreatectomy has been re-evaluated as an effective option to balance both the local control and postoperative safety. In conclusion, more and more aggressive pancreatectomy has become justified by the principle of total neoadjuvant therapy. Further technical standardization and optimal neoadjuvant strategy are mandatory for the global dissemination of aggressive pancreatectomies.

Number Of Patients

Background and Objectives: An increasing number of patients (pts) with locally advanced pancreatic cancer (LAPC) are treated with an intensive neoadjuvant therapy to obtain a secondary curative resection. Only a certain number of patients benefit from this intention. The aim of this investigation was to identify prognostic factors which may predict a benefit for secondary resection. Materials and Methods: Survival time and clinicopathological data of pts with pancreatic cancer were prospective and consecutively collected in our Comprehensive Cancer Center Database. For this investigation, we screened for pts with primarily unresectable pancreatic cancer who underwent a secondary resection after receiving induction therapy in the time between March 2017 and May 2019. Results: 40 pts had a sufficient database to carry out a reliable analysis. The carbohydrate-antigen 19-9 (CA 19-9) level of the pts treated with induction therapy decreased by 44.7% from 4358.3 U/mL to 138.5 U/mL (p = 0.001). The local cancer extension was significantly reduced (p < 0.001), and the Eastern Cooperative Oncology Group (ECOG) performance status was lowered (p = 0.03). The median overall survival (mOS) was 20 months (95% CI: 17.2–22.9). Pts who showed a normal CA 19-9 level (<37 U/mL) at diagnosis and after neoadjuvant therapy or had a Body Mass Index (BMI) below 25 kg/m2 after chemotherapy had a significant prolonged overall survival (29 vs. 19 months, p = 0.02; 26 vs. 18 months, p = 0.04; 15 vs. 24 months, p = 0.01). Pts who still presented elevated CA 19-9 levels >400 U/mL after induction therapy did not profit from a secondary resection (24 vs. 7 months, p < 0.001). Nodal negativity as well as the performance of an adjuvant therapy lead to better mOS (25 vs. 15 months, p = 0.003; 10 vs. 25 months, p < 0.001). Conclusion: The pts in our investigation had different benefits from the multimodal treatment. We identified the CA 19-9 level at time of diagnosis and after neoadjuvant therapy as well as the preoperative BMI as predictive factors for overall survival. Furthermore, diagnostics of presurgical nodal status should gain more importance as nodal negativity is associated with better outcome.

Despite decades of advancement and research into the multimodal care of pancreatic cancer, mortality after the diagnosis of pancreatic ductal adenocarcinoma remains grim. The role of adjuvant therapy following surgical resection has been well established in the literature. However, adjuvant therapy is imperfect, and outside of a clinical trial, there are high rates of omission or delayed initiation of therapy. Neoadjuvant treatment strategies continue to be explored in the management of resectable, borderline-resectable, and locally advanced unresectable pancreatic adenocarcinoma. With improved resection rates and the possibility for tumor downstaging, neoadjuvant therapy has become standard for patients with borderline-resectable and locally advanced unresectable tumors. Additional benefits of neoadjuvant therapy in the treatment of resectable tumors include improved completion rates of systemic therapy and R0 resection rates. Future clinical trials, including the use of novel treatment agents and combination treatment strategies in both neoadjuvant and adjuvant regimens, will add value to the treatment of pancreatic adenocarcinoma. Key words: adjuvant therapy, borderline-resectable pancreatic cancer, locally advanced pancreatic cancer, neoadjuvant therapy, pancreatic adenocarcinoma, resectable disease

Number Of Patients

The incidence of pancreatic cancer continues to rise, and it is now the third-leading cause of cancer-related deaths in the United States. Only 15 to 20% of patients are eligible to undergo potentially curative resection, as most tumors are deemed unresectable at the time of diagnosis because of either locally advanced disease or distant metastases. Improvements in preoperative CT imaging have enabled better determination of the extent of disease and allowed for better operative planning. Based on their relationship to the surrounding vasculature and structures and presence or absence of distant disease, pancreatic tumors are classified into four categories: resectable, borderline resectable pancreatic cancer (BRPC), locally advanced pancreatic cancer (LAPC), and metastatic. With the recent advent of more effective chemotherapy regimens, efforts have focused on using neoadjuvant therapy approaches to increase the likelihood of achieving an R0 in patients with BRPC and possibly convert unresectable, locally advanced tumors to potentially resectable tumors. Response with neoadjuvant therapy regimens has resulted in increased number of patients eligible for resection, many times requiring vascular resection. Herein, we describe recent changes in the classification, important surgical and pathologic considerations and updated multimodal therapeutic options in the complex management of BRPC and LAPC.  This review contains 5 figures, 2 tables, and 78 references.
