Pancreatic neuroendocrine tumors
Current Opinion in Gastroenterology, 2019Pancreatic neuroendocrine tumors (pNETs) are a rare, heterogeneous group of pancreatic neoplasms with a wide range of malignant potential. They may manifest as noninfiltrative, slow-growing tumors, locally invasive masses, or even swiftly metastasizing cancers.In recent years, because of the increasing amount of scientific literature available for ...

Virotherapy of Neuroendocrine Tumors
Neuroendocrinology, 2012Most patients with small intestinal neuroendocrine tumors (SI-NETs), also referred to as midgut carcinoids, present with systemic disease at the time of diagnosis with metastases primarily found in regional lymph nodes and the liver. Curative treatment is not available for these patients and there is a need for novel and specific therapies.

Journal of Computer Assisted Tomography, 2014
Several classification systems for neuroendocrine tumors (NETs) exist, which use variable terminology and criteria for grading and staging. This variability in terminology can cause confusion and difficulty in recognizing which tumors are, in fact, members of this heterogeneous group of malignancies.

Neuroendocrine tumors of the lung
Current Opinion in Oncology, 2008The aim of this article is to answering different questions related to the treatment and prognosis of neuroendocrine lung tumors.In neuroendocrine lung tumors, regardless of the grade of tumoral malignancy, the general growth during the past years of the nodal involvement percentage detected in lung neuroendocrine tumors might be explained by accepting

Pulmonary Neuroendocrine Tumors
Surgical Pathology Clinics, 2020Pulmonary neuroendocrine tumors represent a morphologic spectrum of tumors from the well-differentiated typical carcinoid tumor, to the intermediate-grade atypical carcinoid tumor, to the high-grade neuroendocrine carcinomas composed of small-cell carcinoma and large-cell neuroendocrine carcinoma.

Neuroendocrine Tumors of the Pancreas
Current Treatment Options in Gastroenterology, 2004Neuroendocrine tumors (NETs) are rare tumors of the endocrine pancreas that require a high degree of suspicion for timely diagnosis. Diagnosis is often delayed due to the nonspecific and intermittent presentation of symptoms. As many as 45% to 55% of tumors are nonfunctional and are typically diagnosed secondary to mass effect related symptoms or found

Imaging of Neuroendocrine Tumors
2016Neuroendocrine tumors (NETs) comprise a heterogeneous group of malignancies with a very variable clinical expression and progression. They present unique properties that are important to consider for radiological and nuclear imaging, such as APUD-characteristics (amine precursor uptake and dearboxylation), as well as the expression of somatostatin ...

Neuroendocrine Tumor of the Breast
The American Surgeon™, 2006Mammary carcinoid is an uncommon neoplasm. It accounts for approximately 5 per cent of all breast carcinomas. It is well-known that neuroendocrine elements can be demonstrated in ductal and lobular carcinoma. However, it is still controversial whether mammary carcinoid tumors should be considered a distinct clinical entity or be treated as a variant ...

Neuroendocrine tumors of the larynx
Head & Neck, 1991AbstractA review of the international literature has revealed 68 paragangliomas, 42 large cell, and 74 small cell tumors of the larynx. Paragangliomas are usually benign, although malignant cases have been reported. Large cell tumors are malignancies associated with a high incidence of early cervical metastasis. Small cell tumors are aggressive cancers
