The Tumor Microenvironment in Neuroendocrine Tumors: Biology and Therapeutic Implications.

Neuroendocrinology 2019 Jan 30. Epub 2019 Jan 30.


Neuroendocrine tumors (NETs) include a heterogeneous group of malignancies arising in the diffuse neuroendocrine system and characterized by indolent growth. Complex interactions take place among the cellular components of the microenvironment of these tumors, and the recognition of the molecular mediators of their interplay and cross-talk is crucial to discover novel therapeutic targets. NET cells overexpress a plethora of proangiogenic molecules including VEGF, PDGF, FGF, semaphorins and angiopoietins, that promote both recruitment and proliferation of endothelial cell precursors, thus resulting among the most vascularized cancers with a microvessel density 10-fold higher then epithelial tumors.

A Rare Case of Triple-Negative Essential Thrombocythemia in a Young Postsplenectomy Patient: A Diagnostic Challenge.

Case Rep Hematol 2018 16;2018:9079462. Epub 2018 Dec 16.

Division of Hematology, University of Texas Health Science Center at Houston, Houston, TX, USA.

The distinction between primary and reactive thrombocytosis by bone marrow histology is very important. Reactive thrombocytosis, the most common cause of thrombocytosis, can be expected in postsplenectomy states; however, close hematological evaluation of prolonged thrombocytosis is essential to identify patients who may have an underlying myeloproliferative neoplasm. We report a 37-year-old woman who was found to have portal, mesenteric, and splenic vein thrombosis with thrombocytosis, two months after she had a splenectomy for spontaneous splenic rupture.

Background: When pancreatic neoplasms occlude or encase the superior mesenteric-portal-splenic vein confluence with abutment of the posterior lateral wall of the superior mesenteric artery, a mesocaval shunt with or without a distal splenorenal shunt allows for safe dissection of the porta hepatis and separation of the pancreatic tumor from the superior mesenteric artery. Herein we report long-term results of the largest known series of portosystemic shunts performed at the time of pancreatectomy.

Methods: All patients who underwent pancreatic resection with a mesocaval shunt or distal splenorenal shunt were identified from our prospective database. Read More

Improving prediction of surgical resectability over current staging guidelines in patients with pancreatic cancer who receive stereotactic body radiation therapy.

Adv Radiat Oncol 2018 Oct-Dec;3(4):601-610. Epub 2018 Jul 19.

Department of Radiation Oncology and Molecular Radiation Sciences, Johns Hopkins University School of Medicine, Baltimore, Maryland.

Purpose: For patients with localized pancreatic cancer (PC) with vascular involvement, prediction of resectability is critical to define optimal treatment. However, the current definitions of borderline resectable (BR) and locally advanced (LA) disease leave considerable heterogeneity in outcomes within these classifications. Moreover, factors beyond vascular involvement likely affect the ability to undergo resection. Read More

Laparoscopic management of giant gastrointestinal stromal tumor masquerading as infected mesenteric cyst.

Ann Ital Chir 2018 ;89:342-346

Gastrointestinal stromal tumors (GISTs) are the most common non-epithelial (mesenchymal) tumors of the gastrointestinal tract. Although GISTs appear as solid and well-circumscribed lesions in most patients, they may also appear as solid- cystic (mixed) or pure cystic lesions due to reasons like intra-tumor hemorrhage and necrosis in a very small percentage of patients. Hence, cystic GISTs mostly lead to a diagnostic dilemma. Read More
