One of the main reasons for the dismal prognosis of pancreatic ductal adenocarcinoma (PDAC) is its late diagnosis. At the time of presentation, only approximately 15–20% of all patients with PDAC are considered resectable and around 30% are considered borderline resectable. A surgical approach, which is the only curative option, is limited in borderline resectable patients by local involvement of surrounding structures. In borderline resectable pancreatic cancer (BRPC), neoadjuvant treatment regimens have been introduced with the rationale to downstage and downsize the tumor in order to enable resection and eliminate ­microscopic distant metastases. However, there are no official guidelines for the preoperative treatment of BRPC. In the majority of cases, patients are administered ­Gemcitabine-based or FOLFIRINOX-based chemotherapy regimens with or without radiation. Radiologic restaging after neoadjuvant therapy has to be judged with caution when it comes to predict tumor response and resectability, since inflammation induced by neoadjuvant therapy may mimic solid tumor. Patients who do not show any disease progression during neoadjuvant therapy should be offered surgical exploration, since a high percentage is likely to undergo resection with negative margins (R0) and, thus, achieve improved overall survival although imaging judged it unlikely. Despite the promising new approaches of neoadjuvant treatment regimens during the last 2 decades, surgery remains the first choice if the tumor appears to be primary resectable at the time of diagnosis. At present, there are no international guidelines regarding the preoperative treatment of BRPC. Therefore, in order to standardize and adjust neoadjuvant treatment in the future, new guidelines have to be determined on the basis of upcoming prospective randomized studies.

Background Many patients with borderline resectable/locally advanced pancreatic ductal adenocarcinoma (borderline resectable [BR]/locally advanced [LA] pancreatic ductal adenocarcinoma [PDAC]) undergoing resection will have positive resection margins (R1), which is associated with poor prognosis. It might be useful to preoperatively predict the margin (R) status. Methods Data from patients with BR/LA PDAC who underwent a pancreatectomy between 2008 and 2018 at Brigham and Women’s Hospital were retrospectively reviewed. Logistic regression analysis was used to evaluate the association between R status and relevant preoperative factors. Significant predictors of R1 resection on univariate analysis ( P < .1) were entered into a stepwise selection using the Akaike information criterion to define the final model. Results A total of 142 patients with BR/LA PDAC were included in the analysis, 60(42.3%) had R1 resections. In stepwise selection, the following factors were identified as positive predictors of an R1 resection: evidence of lymphadenopathy at diagnosis (OR = 2.06, 95% CI: 0.99-4.36, P = .056), the need for pancreaticoduodenectomy (OR = 3.81, 96% CI: 1.15-15.70, P = .040), extent of portal vein/superior mesenteric vein involvement at restaging (<180°, OR = 3.57, 95% CI: 1.00-17.00, P = .069, ≥180°, OR = 7,32, 95% CI: 1.75-39.87, P = .010), stable CA 19-9 serum levels (less than 50% decrease from diagnosis to restaging, OR = 2.27, 95% CI: 0.84-6.36 P = .107), and no preoperative FOLFIRINOX (OR = 2.17, 95% CI: 0.86-5.64, P = .103). The prognostic nomogram based on this model yielded a probability of achieving an R1 resection ranging from <5% (0 factors) to >70% (all 5 factors). Conclusions Relevant preoperative clinicopathological characteristics accurately predict positive resection margins in patients with BR/LA PDAC before resection. With further development, this model might be used to preoperatively guide surgical decision-making in patients with BR/LA PDAC.
