CA19-9 Response to First-Line Neoadjuvant FOLFIRINOX and Second-Line Gemcitabine/Nab-Paclitaxel for Patients with Operable Pancreatic Cancer.

Background: Response to second-line (2L) neoadjuvant therapy for operable pancreatic cancer (PC) is understudied. This study examined carbohydrate antigen 19-9 (CA19-9) response to first-line (1L) and 2L chemotherapy.

Methods: The study identified patients with operable PC and elevated CA19-9 (≥ 35 U/mL with total bilirubin < 2 mg/dL) who received 1L FOLFIRINOX (FFX).

Postoperative surveillance of pancreatic ductal adenocarcinoma (PDAC) recurrence: practice pattern on standardized imaging and reporting from the society of abdominal radiology disease focus panel on PDAC.

Purpose: Surgical resection is the only potential curative treatment for patients with pancreatic ductal adenocarcinoma (PDAC), but unfortunately most patients recur within 5 years of surgery. This article aims to assess the practice patterns across major academic institutions and develop consensus recommendations for postoperative imaging and interpretation in patients with PDAC.

Methods: The consensus recommendations for postoperative imaging surveillance following PDAC resection were developed using the Delphi method.

Multimodality Imaging for the Staging of Pancreatic Cancer.

Imaging plays a key role in the diagnosis, staging, and follow-up of pancreatic ductal adenocarcinoma. The pancreatic protocol dual-phase multidetector computed tomography scan is the imaging modality of choice. A computed tomography scan is highly accurate for pancreatic tumor detection, assessment of resectability, and detection of metastatic disease.

Comparison of Conventional Gadoxetate Disodium-Enhanced MRI Features and Radiomics Signatures With Machine Learning for Diagnosing Microvascular Invasion.

This study aimed to determine the best model for predicting microvascular invasion (MVI) of hepatocellular carcinoma (HCC) using conventional gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (gadoxetate disodium)-enhanced MRI features and radiomics signatures with machine learning. This retrospective study included 269 patients with a postoperative pathologic diagnosis of HCC. Gadoxetate disodium-enhanced MRI features were assessed, including T1 relaxation time, tumor margin, tumor size, peritumoral enhancement, peritumoral hypointensity, and ADC.

Value of Pretreatment F-fluorodeoxyglucose Positron Emission Tomography in Patients With Localized Pancreatic Cancer Treated With Neoadjuvant Therapy.

F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) imaging is not routine in patients with localized pancreatic cancer (PC). We evaluated the prognostic value of PET/CT in patients who received neoadjuvant therapy. Patients with localized PC underwent pretreatment PET/CT with or without posttreatment (preop) PET/CT.

Salvage ipilimumab associated with a significant response in sarcomatoid renal cell carcinoma.

Background: Metastatic sarcomatoid renal cell carcinoma (sRCC) is an aggressive variant of RCC with generally poor prognosis. Treatment with vascular endothelial growth factor inhibitors or chemotherapy generates only short-lived responses. Recent research has suggested a role for combination checkpoint inhibition as first line treatment for metastatic sRCC.

White paper on pancreatic ductal adenocarcinoma from society of abdominal radiology's disease-focused panel for pancreatic ductal adenocarcinoma: Part II, update on imaging techniques and screening of pancreatic cancer in high-risk individuals.

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive gastrointestinal malignancy with a poor 5-year survival rate. Its high mortality rate is attributed to its aggressive biology and frequently late presentation. While surgical resection remains the only potentially curative treatment, only 10-20% of patients will present with surgically resectable disease.

White paper on pancreatic ductal adenocarcinoma from society of abdominal radiology's disease-focused panel for pancreatic ductal adenocarcinoma: Part I, AJCC staging system, NCCN guidelines, and borderline resectable disease.

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive gastrointestinal malignancy with a poor 5-year survival rate. Accurate staging of PDAC is an important initial step in the development of a stage-specific treatment plan. Different staging systems/consensus statements convened by different societies and academic practices are currently used.

Survival of patients with borderline resectable pancreatic cancer who received neoadjuvant therapy and surgery.

Background: It is difficult to successfully deliver multimodality therapy to patients with operable pancreatic cancer. Data on the natural history of such efforts are necessary for physicians to guide shared decision-making with patients and families. We report the survival of consecutive patients with borderline resectable pancreatic cancer who received neoadjuvant therapy before surgery.

Structured Reporting in Ultrasound.

Structured reporting of ultrasound examinations can add value throughout the imaging chain. Reports may be created in a more efficient manner, with increased accuracy and clarity. Communication with referring providers and patients may be improved.

A Phase II Clinical Trial of Molecular Profiled Neoadjuvant Therapy for Localized Pancreatic Ductal Adenocarcinoma.

Objectives: One facet of precision medicine is the use of tumor molecular profiling to guide chemotherapeutic selection. We conducted the first prospective clinical trial of molecular profiling to guide neoadjuvant therapy in patients with operable pancreatic ductal adenocarcinoma (PDAC). We hypothesized that more effective systemic therapy would prevent disease progression during neoadjuvant therapy and, therefore, allow more patients to undergo surgery.

Locally advanced pancreas cancer: Staging and goals of therapy.

Background: Patients with locally advanced pancreatic cancer have historically been considered inoperable. The purpose of this report was to determine resectability rates for patients with locally advanced pancreatic cancer based on our recently described definitions of type A and type B locally advanced pancreatic cancer.

Methods: An institutional prospective pancreas cancer database was queried for consecutive patients with locally advanced pancreatic cancer treated between January 2009 and June 2017.

Characterizing indeterminate liver lesions in patients with localized pancreatic cancer at the time of diagnosis.

Background: In patients with newly diagnosed pancreatic cancer, the classification of indeterminate liver lesions is an unanswered clinical dilemma as misclassification of these lesions can impact the assignment of clinical stage and subsequent treatment planning. Our objective was to design a standardized classification system to more accurately define the risk of malignancy in indeterminate liver lesions.

Methods: In this retrospective study, patients with localized, non-metastatic pancreatic cancer were identified and pre-treatment computed tomography (CT) scans were evaluated for the presence or absence of liver lesions.

Pancreatic adenocarcinoma: cross-sectional imaging techniques.

Pancreatic adenocarcinoma is a common malignancy that has a poor prognosis. Imaging is vital in its detection, staging, and management. Although a variety of imaging techniques are available, MDCT is the preferred imaging modality for staging and assessing the resectability of pancreatic adenocarcinoma.

Development of a high risk pancreatic screening clinic using 3.0 T MRI.

Selective screening for pancreatic cancer (PC) has been proposed. We describe the establishment of a comprehensive multidisciplinary screening program using 3.0 T MRI.

Venous thromboembolism prophylaxis during neoadjuvant therapy for resectable and borderline resectable pancreatic cancer-Is it indicated?

Purpose: To describe venous thromboembolism (VTE) rates in patients with pancreatic cancer (PC) during neoadjuvant therapy.

Methods: Factors associated with VTE were evaluated using multivariable logistic regression modeling in patients with resectable and BLR PC treated with neoadjuvant therapy between 2009 and 2014.

Results: Prevalent VTEs were detected in 13 (5%) of the 260 patients.

Evolution of the Management of Resectable Pancreatic Cancer.

In pancreatic cancer, as with many other solid tumors, a commonly held surgical adage-a chance to cut is a chance to cure-has been promulgated throughout the years. Following such reasoning, surgical extirpation of a localized tumor would prevent tumor dissemination and metastatic tumor progression. However, decades of surgical experience have demonstrated that surgical resection alone provides a limited median survival benefit.

Neoadjuvant treatment sequencing adds value to the care of patients with operable pancreatic cancer.

Treatment sequencing for resectable pancreatic cancer remains controversial and there is lack of level one evidence comparing neoadjuvant versus adjuvant strategies. However, a comparison of the cost-effectiveness analysis of the treatment strategies may help to better define the healthcare value of each approach. This review will highlight the rationale for multimodality therapy in the treatment of pancreatic cancer, discuss the advantages and disadvantages of adjuvant therapy, and conceptualize the cost-effectiveness of a neoadjuvant approach with regard to healthcare value.

Survival of patients with resectable pancreatic cancer who received neoadjuvant therapy.

Background: Enthusiasm for neoadjuvant therapy is growing from the emerging consensus that pancreatic cancer is a systemic disease at the time of diagnosis. Those who remain in favor of upfront surgery often cite the lack of reported data to support alternative treatment sequencing. We therefore report the results of all patients treated outside of a clinical trial under the direction of a multidisciplinary pancreatic cancer working group.

Neoadjuvant therapy for localized pancreatic cancer: guiding principles.

The management of localized pancreatic cancer (PC) remains controversial. Historically, patients with localized disease have been treated with surgery followed by adjuvant therapy (surgery-first approach) under the assumption that surgical resection is necessary, even if not sufficient for cure. However, a surgery-first approach is associated with a median overall survival of only 22-24 months, suggesting that a large proportion of patients with localized PC have clinically occult metastatic disease.

Pancreas transplant imaging: how I do it.

Pancreas transplantation aims to restore physiologic normoglycemia in diabetic patients with glomerulopathy and avoid or delay the onset of diabetic retinopathy and arteriopathy. Simultaneous pancreas-kidney transplant is the most common approach, using a cadaveric pancreas donation in conjunction with either cadaveric or live donor renal transplant. Alternative techniques include pancreas after kidney transplant, in which the pancreas transplant is performed some years after renal transplant.

Arterial resection at the time of pancreatectomy for cancer.

Background: Tumor-induced arterial abutment/encasement has been traditionally a contraindication to surgery in patients with localized pancreatic cancer (PC). One recent meta-analysis reported greater mortality rates in this setting. We report herein a series of planned arterial resections in carefully selected patients who responded favorably to combined modality therapy for localized PC.
