Current management and future directions in metastatic pancreatic adenocarcinoma.

ABSTRACT: Of the anticipated 50,000 individuals expected to be diagnosed with pancreatic cancer in 2016, the majority will have metastatic disease. Given the noncurative nature of advanced pancreatic adenocarcinoma, treatment is aimed at inducing disease regression, controlling symptom, and extending life. The last 5 years have been marked by advances in the treatment of metastatic pancreatic cancer, specifically the approval by the US Food and Drug Administration of 2 combination chemotherapy regimens and the widespread use of a third, which have reproducibly been shown to improve survival. Ongoing studies are building on these regimens along with targeted and immunotherapeutic agents. This article will review the current treatment standards and emerging targets for metastatic pancreatic cancer. Cancer 2016;122:3765-3775. © 2016 American Cancer Society.

Project description:IntroductionPancreatic adenocarcinoma (PAC) has some of the worst treatment outcomes for any solid tumor. PAC creates substantial difficulty for effective treatment with traditional RT delivery strategies primarily secondary to its location and limited visualization using CT. Several of these challenges are uniquely addressed with MR-guided RT. We sought to summarize and place into context the currently available literature on MR-guided RT specifically for PAC.MethodsA literature search was conducted to identify manuscript publications since September 2014 that specifically used MR-guided RT for the treatment of PAC. Clinical outcomes of these series are summarized, discussed, and placed into the context of the existing pancreatic literature. Multiple international experts were involved to optimally contextualize these publications.ResultsOver 300 manuscripts were reviewed. A total of 6 clinical outcomes publications were identified that have treated patients with PAC using MR guidance. Successes, challenges, and future directions for this technology are evident in these publications. MR-guided RT holds theoretical promise for the treatment of patients with PAC. As with any new technology, immediate or dramatic clinical improvements associated with its use will take time and experience. There remain no prospective trials, currently publications are limited to small retrospective experiences. The current level of evidence for MR guidance in PAC is low and requires significant expansion. Future directions and ongoing studies that are currently open and accruing are identified and reviewed.ConclusionsThe potential promise of MR-guided RT for PAC is highlighted, the challenges associated with this novel therapeutic intervention are also reviewed. Outcomes are very early, and will require continued and long term follow up. MR-guided RT should not be viewed in the same fashion as a novel chemotherapeutic agent for which dosing, administration, and toxicity has been established in earlier phase studies. Instead, it should be viewed as a novel procedural intervention which must be robustly tested, refined and practiced before definitive conclusions on the potential benefits or detriments can be determined. The future of MR-guided RT for PAC is highly promising and the potential implications on PAC are substantial.
