Impact of pathological response after neoadjuvant chemotherapy on adjuvant therapy decisions and patient outcomes in gastrointestinal cancers.

Background: Neoadjuvant chemotherapy (NAC) is frequently used in gastrointestinal cancers (GIC), and pathological, radiological, and tumor marker responses are assessed during and after NAC.

Aim: To evaluate the relationship between pathologic, radiologic, tumor marker responses and recurrence-free survival (RFS), overall survival (OS), adjuvant chemotherapy (AC) decisions, and the impact of changing to a different AC regimen after poor response to NAC.

Methods And Results: Medical records of GIC patients treated with NAC at Mount Sinai between 1/2012 and 12/2018 were reviewed.

Implementation and evaluation of a performance improvement intervention to address physician documentation deficiencies in abdominal ultrasound.

Purpose: For ultrasound reports to meet criteria for coding as abdomen complete (USABC), 8 elements are required: liver, bile ducts, gallbladder, spleen, kidneys, pancreas, inferior vena cava (IVC), and aorta. Failure to document all 8 results in coding as ultrasound abdomen limited. The purposes of our study were to identify deficiencies in documentation, implement a performance improvement intervention to address deficiencies, and evaluate the intervention.

Radiographic findings of anastomotic leaks.

Although computed tomography (CT) scans play an important role in the diagnosis and management of anastomotic leaks (AL), there is no consensus on what radiographic findings are associated with AL. The purpose of this study is to identify the most common CT scan findings associated with AL and whether the amount of extraluminal air or the density of extraluminal fluid can be correlated with the presence of an AL. A retrospective chart review of 210 patients with anastomotic leaks from 2003 to 2010 at Mount Sinai Medical Center was performed.

Intraductal polypoid lipid-rich neuroendocrine tumor of the pancreas with entrapped ductules: case report and review of the literature.

Pancreatic neuroendocrine tumors of the main pancreatic duct are rare and usually small due to symptoms of pancreatic duct obstruction. We present a case of a large (3 cm), well-differentiated (G1) lipid-rich polypoid neuroendocrine tumor of the pancreas completely occluding the main pancreatic duct with non-neoplastic-entrapped ductules and CK19 positivity. Clinical, radiological, gross, microscopic, immunohistochemical, and ultrastructural findings are discussed.

Hepatic imaging in the 21st century.

Imaging of the liver has progressed rapidly during the past decade with continued advancement of current ultrasound, computed tomography, and magnetic resonance imaging (MRI). Each modality not only has seen refinement enabling better anatomic characterization of disease but also has received strength from the addition of new techniques to its resources. New contrast agents have become available for all modalities and some agents, particularly for MRI, have opened the way for better functional assessment.
