ABSTRACT: Ductal adenocarcinoma and its variants account for most pancreatic malignancies. High-quality multiphase imaging can help to preoperatively distinguish between patients eligible for resection with curative intent and those with unresectable disease. Systemic therapy is used in the neoadjuvant or adjuvant pancreatic cancer setting, as well as in the management of locally advanced unresectable and metastatic disease. Clinical trials are critical for making progress in treatment of pancreatic cancer. The NCCN Guidelines for Pancreatic Adenocarcinoma focus on diagnosis and treatment with systemic therapy, radiation therapy, and surgical resection.

ABSTRACT: The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Pancreatic Adenocarcinoma discuss the workup and management of tumors of the exocrine pancreas. These NCCN Guidelines Insights provide a summary and explanation of major changes to the 2012 NCCN Guidelines for Pancreatic Adenocarcinoma. The panel made 3 significant updates to the guidelines: 1) more detail was added regarding multiphase CT techniques for diagnosis and staging of pancreatic cancer, and pancreas protocol MRI was added as an emerging alternative to CT; 2) the use of a fluoropyrimidine plus oxaliplatin (e.g., 5-FU/leucovorin/oxaliplatin or capecitabine/oxaliplatin) was added as an acceptable chemotherapy combination for patients with advanced or metastatic disease and good performance status as a category 2B recommendation; and 3) the panel developed new recommendations concerning surgical technique and pathologic analysis and reporting.

4 Review The role of intraoperative radiation therapy in patients with pancreatic cancer. 2014

Palta, Manisha / Willett, Christopher / Czito, Brian. ·Department of Radiation Oncology, Duke University, Durham, NC. · Department of Radiation Oncology, Duke University, Durham, NC. Electronic address: Brian.czito@duke.edu. ·Semin Radiat Oncol · Pubmed #24635869.

ABSTRACT: Intraoperative radiation therapy (IORT) techniques allow for the delivery of high doses of radiation therapy while excluding part or all of the nearby dose-limiting sensitive structures. Therefore, the effective radiation dose is increased and local tumor control potentially improved. This is pertinent in the case of pancreatic cancer because local failure rates are as high as 50%-80% in patients with resected and locally advanced disease. Available data in patients receiving IORT after pancreaticoduodenectomy reveal an improvement in local control, though overall survival benefit is unclear. Series of patients with locally advanced pancreatic cancer also suggest pain relief, and in select studies, improved survival associated with the inclusion of IORT. At present, no phase III data clearly supports the use of IORT in the management of pancreatic cancer.

5 Review Role of radiation therapy in patients with resectable pancreatic cancer. 2011

Palta, Manisha / Willett, Christopher / Czito, Brian. ·Department of Radiation Oncology, Duke University Medical Center, Durham, North Carolina 27710, USA. ·Oncology (Williston Park) · Pubmed #21874833.

ABSTRACT: The 5-year overall survival of patients with pancreatic cancer is approximately 5%, with potentially resectable disease representing the curable minority. Although surgical resection remains the cornerstone of treatment, local and distant failure rates are high after complete resection, and debate continues as to the appropriate adjuvant therapy. Many oncologists advocate for adjuvant chemotherapy alone, given that high rates of systemic metastases are the primary cause of patient mortality. Others, however, view locoregional failure as a significant contributor to morbidity and mortality, thereby justifying the use of adjuvant chemoradiation. As in other gastrointestinal malignancies, neoadjuvant chemoradiotherapy offers potential advantages in resectable patients, and clinical investigation of this approach has shown promising results; however, phase III data are lacking. Further therapeutic advances and prospective trials are needed to better define the optimal role of adjuvant and neoadjuvant treatment in patients with resectable pancreatic cancer.

6 Review Is there a role for advanced radiation therapy technologies in the treatment of pancreatic adenocarcinoma? 2008

Meyer, Jeffrey John / Willett, Christopher George / Czito, Brian Gary. ·Duke University Medical Center, Department of Radiation Oncology, DUMC Box 3085, Durham, NC 27710, USA. jeffrey.meyer@duke.edu ·Future Oncol · Pubmed #18407737.

ABSTRACT: Pancreatic cancer remains a highly challenging problem in oncology. Oncologists continue to search for therapies that are more effective than those currently available to improve on the existing poor treatment results. Persistence of both systemic and local disease causes high rates of morbidity and mortality for patients. Radiation continues to play a role in the treatment of pancreatic cancer, in both the adjuvant and locally advanced settings. Efforts to improve on the results of radiotherapy have led to the use of new and improved technologies. This review discusses a variety of these technological improvements and their current and potential future roles in the clinic.

ABSTRACT: PURPOSE: Diffusion-weighted Magnetic Resonance Imaging (DWI) has been shown to be a powerful tool for cancer detection with high tumor-to-tissue contrast. This study aims to investigate the feasibility of developing a four-dimensional DWI technique (4D-DWI) for imaging respiratory motion for radiation therapy applications. MATERIALS/METHODS: Image acquisition was performed by repeatedly imaging a volume of interest (VOI) using an interleaved multislice single-shot echo-planar imaging (EPI) 2D-DWI sequence in the axial plane. Each 2D-DWI image was acquired with an intermediately low b-value (b = 500 s/mm RESULTS: Tumor trajectories extracted from XCAT 4D-DWI were consistent with the input signal: the average D value was 1.9 mm (SI) and 0.4 mm (AP). The average D value was 2.6 mm (SI) and 1.7 mm (AP) for the two healthy volunteers. CONCLUSION: A 4D-DWI technique has been developed and evaluated on digital phantom and human subjects. 4D-DWI can lead to more accurate respiratory motion measurement. This has a great potential to improve the visualization and delineation of cancer tumors for radiotherapy.

ABSTRACT: The NCCN Guidelines for Pancreatic Adenocarcinoma discuss the diagnosis and management of adenocarcinomas of the exocrine pancreas and are intended to assist with clinical decision-making. These NCCN Guidelines Insights summarize major discussion points from the 2014 NCCN Pancreatic Adenocarcinoma Panel meeting. The panel discussion focused mainly on the management of borderline resectable and locally advanced disease. In particular, the panel discussed the definition of borderline resectable disease, role of neoadjuvant therapy in borderline disease, role of chemoradiation in locally advanced disease, and potential role of newer, more active chemotherapy regimens in both settings.

9 Article Does preoperative therapy optimize outcomes in patients with resectable pancreatic cancer? 2012

ABSTRACT: The objective of this study was to compare survival between all patients with radiographically resectable adenocarcinoma of the proximal pancreas who underwent preoperative chemoradiation therapy (PRE-OP CRT) or surgical exploration first (SURGERY) with "intention to resect." Pancreatic cancer patients who undergo resection after PREOP CRT live longer than patients who undergo resection without PREOP CRT, a difference that may be attributable to patient selection. We retrospectively identified 236 patients with pancreatic head adenocarcinoma seen between 1999 and 2007 with sufficient data to be confirmed medically and radiographically resectable. The outcomes of 144 patients who underwent PREOP CRT were compared to those of 92 patients who proceeded straight to SURGERY. The groups were similar in age and gender. Tumors were slightly larger in the PREOP CRT group (mean 2.5 cm vs. 2.1 cm, P < 0.01), and there were trends toward more venous abutment (54% vs. 39%, P = 0.06) and a higher Charlson comorbidity index (P = 0.1). In the PREOP CRT group, 76 patients (53%) underwent resection, 28 (19%) had metastatic and 17 (12%) locally unresectable disease after PREOP CRT, and 23 (16%) were not explored due to performance status or loss to follow-up. In the SURGERY group, 68 patients (74%) underwent resection. Sixteen patients (17%) had metastatic and eight patients (9%) locally unresectable disease at exploration. In patients who underwent resection, the PREOP CRT group had smaller pathologic tumor size and lower incidence of positive lymph nodes than the SURGERY group but no difference in positive margins or need for vascular resection. Median overall survival (OS) in patients undergoing resection was 27 months in the PREOP CRT group and 17 months in the SURGERY group (P = 0.04). Median OS in all patients treated with PREOP CRT or surgically explored with intention to resect was 15 and 13 months, respectively, with superimposable survival curves. Despite a lower resection rate, the PREOP CRT group as a whole had a similar OS to the SURGERY group as a whole. For patients who underwent resection, those in the PREOP CRT had longer survival than those in the SURGERY group, suggesting that PREOP CRT allows better patient selection for resection. PREOP CRT should be considered an acceptable alternative for most patients with resectable pancreatic cancer.

10 Article Resected pancreatic neuroendocrine tumors: patterns of failure and disease-related outcomes with or without radiotherapy. 2012

Zagar, Timothy M / White, Rebekah R / Willett, Christopher G / Tyler, Douglas S / Papavassiliou, Paulie / Papalezova, Katia T / Guy, Cynthia D / Broadwater, Gloria / Clough, Robert W / Czito, Brian G. ·Department of Radiation Oncology, University of North Carolina, Chapel Hill, NC, USA. ·Int J Radiat Oncol Biol Phys · Pubmed #22270161.

ABSTRACT: PURPOSE: Pancreatic neuroendocrine tumors (NET) are rare and have better disease-related outcomes compared with pancreatic adenocarcinoma. Surgical resection remains the standard of care, although many patients present with locally advanced or metastatic disease. Little is known regarding the use of radiotherapy in the prevention of local recurrence after resection. To better define the role of radiotherapy, we performed an analysis of resected patients at our institution. METHODS: Between 1994 and 2009, 33 patients with NET of the pancreatic head and neck underwent treatment with curative intent at Duke University Medical Center. Sixteen patients were treated with surgical resection alone while an additional 17 underwent resection with adjuvant or neoadjuvant radiation therapy, usually with concurrent fluoropyrimidine-based chemotherapy (CMT). Median radiation dose was 50.4 Gy and median follow-up 28 months. RESULTS: Thirteen patients (39%) experienced treatment failure. Eleven of the initial failures were distant, one was local only and one was local and distant. Two-year overall survival was 77% for all patients. Two-year local control for all patients was 87%: 85% for the CMT group and 90% for the surgery alone group (p = 0.38). Two-year distant metastasis-free survival was 56% for all patients: 46% and 69% for the CMT and surgery patients, respectively (p = 0.10). CONCLUSIONS: The primary mode of failure is distant which often results in mortality, with local failure occurring much less commonly. The role of radiotherapy in the adjuvant management of NET remains unclear.
