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.

2 Article Healthcare disparities in outcomes of patients with resectable pancreatic cancer. 2019

ABSTRACT: BACKGROUND: The aim of this study was to evaluate health disparities in the outcomes of patients with resectable pancreatic adenocarcinoma. METHODS: We retrospectively analyzed 280,935 patients from the National Cancer Data Base (NCDB), from 1998 to 2012 to compare the differences in patient characteristics, refusal of offered surgical treatment and overall survival after pancreatic adenocarcinoma resection between white vs. black patients. RESULTS: Black patients did not undergo and refused offered surgical treatment more frequently. Race and insurance were the most important factors independently associated with not receiving the offered resection. Having private insurance, Hispanic ethnic background, geographic location, higher income, residing in urban/metropolitan area and systemic treatment were independently associated with improved survival. Race was associated with overall worse survival in an unadjusted model but not in multivariable analysis. The association between race and survival was removed when adjusting for facility location, income, education, tumor size, tumor stage or systemic treatment. CONCLUSION: Disparities exist at various levels in resectable pancreatic cancers. These findings help developing targeted interventions and quality improvement initiatives.

ABSTRACT: BACKGROUND: We evaluated the role of lymph node (LN) retrieval in pancreatic adenocarcinoma (PA) patients undergoing pancreaticoduodenectomy (PD). METHODS: We utilized the National Cancer Data Base; Cox regression models and logistic regression models were used for statistical evaluation. RESULTS: We evaluated 26,792 patients with PA who underwent PD. The mean LN retrieved in LN(-) patients was 10.8 vs 14.4 for LN(+) patients (P < 0.0001). Greater LN retrieval is an independent predictor of a negative microscopic margin and decreased length of stay. The median survival of LN(-) patients exceeded that of LN(+) patients (24.5 vs 15.1 months, P < 0.0001). Increasing LN retrieval is a significant predictor of survival in all patients, and in LN(-) patients. The relationship of increased LN retrieval and enhanced survival is a nearly linear trend. CONCLUSIONS: Rather than demonstrating an inflection point that defines the extent of adequate lymphadenectomy, this dataset demonstrates an incremental relationship between LN retrieval and survival.

4 Article Impact of the time interval between MDCT imaging and surgery on the accuracy of identifying metastatic disease in patients with pancreatic cancer. 2015

Raman, Siva P / Reddy, Sushanth / Weiss, Matthew J / Manos, Lindsey L / Cameron, John L / Zheng, Lei / Herman, Joseph M / Hruban, Ralph H / Fishman, Elliot K / Wolfgang, Christopher L. ·1 Department of Radiology, Johns Hopkins University School of Medicine, JHOC 3251, 601 N Caroline St, Baltimore, MD 21287. ·AJR Am J Roentgenol · Pubmed #25539271.

ABSTRACT: OBJECTIVE: Pancreatic adenocarcinoma is a rapidly progressive malignancy characterized by its tendency for early metastatic spread. MDCT is the primary diagnostic modality for the preoperative staging of patients with pancreatic cancer, with an accuracy established in multiple studies. However, for a variety of reasons, there is often a prolonged interval between staging MDCT and the surgical intervention. This study examines the relationship between the interval between imaging and surgery and the accuracy of MDCT in determining the presence or absence of metastatic disease at surgery in patients with pancreatic cancer. MATERIALS AND METHODS: Patients were identified who had undergone surgery for pancreatic cancer at our institution with a dedicated preoperative pancreas-protocol MDCT performed in our department. Findings from the preoperative MDCT report were correlated with the operative findings, as well as the time between imaging and surgery. RESULTS: Two hundred ninety-two MDCT scans were performed on 256 patients who underwent exploration for pancreatic adenocarcinoma. The patients had a median age of 67 years (range, 30-95 years), and 51.6% (132/256) were male. The median time between MDCT and surgical exploration was 15.5 days (range, 1-198 days). MDCT correctly predicted the absence of metastatic disease at surgery in 233 of 274 (85.0%) studies. MDCT was more accurate in predicting the absence of metastatic disease if the study was performed within 25 days of surgery than it was if the study was performed within more than 25 days of surgery (89.3% vs 77.0%; p = 0.0097). Furthermore, regression models showed that the negative predictive value of a given MDCT significantly decreased after approximately 4 weeks. CONCLUSION: MDCT is an accurate method to stage patients with pancreatic cancer, but its accuracy in excluding distant metastatic disease depreciates over time. Patients should undergo a repeat MDCT within 25 days of any planned definitive operative intervention for pancreatic cancer to avoid unexpectedly finding metastatic disease at surgery.

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.

6 Article Histopathologic basis for the favorable survival after resection of intraductal papillary mucinous neoplasm-associated invasive adenocarcinoma of the pancreas. 2010

Poultsides, George A / Reddy, Sushanth / Cameron, John L / Hruban, Ralph H / Pawlik, Timothy M / Ahuja, Nita / Jain, Ajay / Edil, Barish H / Iacobuzio-Donahue, Christine A / Schulick, Richard D / Wolfgang, Christopher L. ·Department of Surgery, Sidney Kimmel Cancer Center, Johns Hopkins Hospital, Baltimore, MD, USA. ·Ann Surg · Pubmed #20142731.

ABSTRACT: OBJECTIVE: To identify pathologic features that may account for the favorable survival after resection of invasive pancreatic adenocarcinoma arising in the setting of intraductal papillary mucinous neoplasm (IPMN) compared with standard pancreatic ductal adenocarcinoma (PDA) in the absence of IPMN. SUMMARY BACKGROUND DATA: The 5-year survival after resection of IPMN-associated invasive adenocarcinoma is reported to be between 40% and 60%, which is superior to the 10-25%, typically cited after resection of standard PDA. It remains unclear whether this represents distinct biology or simply a tendency for earlier presentation of IPMN-associated invasive adenocarcinoma. METHODS: A single institution's prospective pancreatic resection database was retrospectively reviewed to identify patients with invasive pancreatic adenocarcinoma who underwent pancreatectomy with curative intent. Log rank and Cox regression analysis were used to identify factors associated with survival. RESULTS: From 1995 to 2006, 1260 consecutive patients were identified, 132 (10%) with IPMN-associated invasive adenocarcinoma and 1128 (90%) with standard PDA. Actuarial 5-year survival was 42% after resection for IPMN-associated versus 19% for standard PDA (P < 0.001). However, compared with standard PDA, invasive adenocarcinoma arising within an IPMN was associated with a lower incidence of (1) advanced T stage (T2-T4, 96% vs. 73%, P < 0.001); (2) regional lymph node metastasis (78% vs. 51%, P < 0.001); (3) poor tumor differentiation (44% vs. 26%, P < 0.001); (4) vascular invasion (54% vs. 33%, P < 0.001); (5) perineural invasion (92% vs. 63%, P < 0.001); and (6) microscopic margin involvement (28% vs. 14%, P < 0.001). Specifically, in the presence of any one of the aforementioned adverse pathologic characteristics, outcomes after resection for IPMN-associated and standard PDA were not significantly different. CONCLUSION: The favorable biologic behavior of IPMN-associated compared with standard PDA is based on its lower rate of advanced T stage, lymph node metastasis, high tumor grade, positive resection margin, perineural, and vascular invasion. In the presence of any one of the aforementioned adverse pathologic characteristics, however, survival outcomes after resection of IPMN-associated and after resection of standard pancreatic adenocarcinoma are similar.
