Endoscopic Ultrasound-Guided Therapies in Patients with Pancreatic Neuroendocrine Tumors.

Pancreatic neuroendocrine neoplasms (PNETs) are rare but can be associated with significant morbidity and mortality. PNETs can be difficult to diagnose and have a propensity for metastasis before their diagnosis is established. To this end, many PNETs do not become apparent until late in their clinical course.

Endoscopic management of pancreatic walled-off necrosis.

Pancreatic walled-off necrosis (WON) is a complication of severe pancreatitis. Endoscopic transmural drainage has been recognized as the first-line treatment for pancreatic fluid collections. Endoscopy offers a minimally invasive approach when compared to surgical drainage.

Bacterial Involvement in Progression and Metastasis of Adenocarcinoma of the Stomach.

Gastric cancer metastasis is a process in which the tumor microenvironment may carry significant influence. () infection is well-established as a contributor to gastric carcinoma. However, the role that these bacteria and others may play in gastric carcinoma metastasis is a current focus of study.

Bacterial Involvement in Progression and Metastasis of Colorectal Neoplasia.

While the gut microbiome is composed of numerous bacteria, specific bacteria within the gut may play a significant role in carcinogenesis, progression, and metastasis of colorectal carcinoma (CRC). Certain microbial species are known to be associated with specific cancers; however, the interrelationship between bacteria and metastasis is still enigmatic. Mounting evidence suggests that bacteria participate in cancer organotropism during solid tumor metastasis.
