First Choice

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.

256 Background: Trials examining the use of FOLFIRINOX in metastatic pancreatic ductal adenocarcinoma demonstrate significantly higher response rates compared to gemcitabine-based regimens. These high response rates may be particularly important for patients with locally advanced pancreatic ductal adenocarcinoma (LAPD), in which there is currently limited experience with FOLFIRINOX. We examined the outcomes of patients with LAPD treated with neoadjuvant FOLFIRINOX at our high volume clinic. Methods: Retrospective review of a prospectively maintained pancreatic cancer database was used to identify patients who were recommended neoadjuvant treatment with FOLFIRINOX. Clinical outcomes were reviewed. Resectability was determined using SSO criteria. Results: Between 2/2011 and 9/2012 FOLFIRINOX was recommended for 25 patients with LAPD, 13 (52%) unresectable (UR) and 12 (48%) borderline resectable (BR). Median age was 59. 4 patients (16%) either refused treatment or were lost to follow up. 21 patients (84%) were treated with a median of 4.7 cycles (Range: 2-8). 5 patients (24%) required dose reductions secondary to toxicity. 2 patients (9%) were unable to tolerate treatment and 3 patients (14%) had disease progression on treatment. Of the remaining 16 patients, 13 patients (62%) displayed a radiologic response allowing for surgical exploration, 4 (31%) of which were initially unresectable. 6 of these patients (29%) received additional chemotherapy and/or radiation therapy prior to surgery. Peritoneal metastases were discovered at surgery in 2 (8%) patients. Of the patients who were BR, 7/8 (88%) had a R0 resection. Of the 10 UR patients, 3 (33%) underwent surgical resection, with 2 (20%) R0 resections. Overall R0 resection rate was 43%. A total of 4 patients (19%) demonstrated a major pathologic response (2 complete responses and 2 near complete responses) and 8 other patients (73%) had some pathological response. Conclusions: FOLFIRINOX alone or as part of multimodality approach is a biologically active regimen in LAPD with encouraging R0 resection rates, especially in BR LAPD. Further research is needed to determine the utility of additional chemoradiotherapy with FOLFIRINOX and to identify predictors of response in UR patients.

Clinical Consequences

Pancreatic ductal adenocarcinoma (PDAC) is the most common form of pancreatic cancer and carries a dismal prognosis. Resectable patients are treated predominantly with surgery while borderline resectable patients may receive neoadjuvant treatment (NAT) to downstage their disease prior to possible resection. PDAC tissue is stiffer than healthy pancreas, and tissue stiffness is associated with cancer progression. Another feature of PDAC is increased tissue heterogeneity. We postulate that tumour stiffness and heterogeneity may be used alongside currently employed diagnostics to better predict prognosis and response to treatment. In this review we summarise the biomechanical changes observed in PDAC, explore the factors behind these changes and describe the clinical consequences. We identify methods available for assessing PDAC biomechanics ex vivo and in vivo, outlining the relative merits of each. Finally, we discuss the potential use of radiological imaging for prognostic use.
