There is limited information using irreversible electroporation to treat pancreatic tumors. We report a case of a 78-year-old male who underwent irreversible electroporation of a pancreatic neuroendocrine tumor.

Cerebellar, brainstem and spinal cord metastases from esophageal cancer following radiotherapy are extremely rare. The current study presents the case of a 74-year-old male who was admitted to the Zhejiang Cancer Hospital (Hangzhou, China) with a poorly-differentiated neuroendocrine carcinoma of the esophagus. Following radiotherapy, multiple abnormal signals in the brainstem and spinal cord we...

BACKGROUND AND PURPOSE On diffusion-weighted imaging (DWI), metastatic tumors of the brain may exhibit different signal intensities (SI) depending on their histology and cellularity. The purpose of our study was to verify the hypotheses (1) that SI on DWI predict the histology of metastases and (2) that apparent diffusion coefficient (ADC) values reflect tumor cellularity. MATERIALS AND METHO...

Neuroendocrine tumors may develop throughout the human body with the majority being found in the gastrointestinal tract and bronchopulmonary system. Neuroendocrine tumors are classified according to the grade of biological aggressiveness (G1-G3) and the extent of differentiation (well-differentiated/poorly-differentiated). The well-differentiated neoplasms comprise typical (G1) and atypical (G2...

INTRODUCTION Neuroendocrine tumors arising primarily in the bile duct are rare. And among these tumors, mixed adeno-neuroendocrine carcinoma (MANEC) is quite uncommon. We report a patient with MANEC who achieved long-term recurrence-free survival. And our case report includes analysis previous case reports. PRESENTATION OF CASE A 66-year-old man underwent investigation for persistent anorexia...

Gastric neuroendocrine tumour (GNET), also known as carcinoids, are a very rare cause of gastric outlet obstruction and arise from entero-chromaffin like cells the mucosa. They account for 0.2/1000001 population 8.7% all Gastrointestinal carcinoids. four types based on degree differentiation, cell origin other pathologic features. Type 4 GNET referred to carcinoma accounting <1% GNET. aggres...

radioiodine (1-131) is the treatment of choice in differentiated thyroid carcinoma. external radiotlierapy however, has it's own roie in these tumors. treatment of anaplastic thyroid carcinoma 1ms not acliieved any notahle success yet, though combined - modality regimens of radiotherapy and chemotherapy have sometimes shown significant results. in this paper the role of radiotlierapy and chemot...

BACKGROUND To determine the prognostic relevance of neuroendocrine differentiation in poorly differentiated colorectal cancer. METHODS The clinicopathological features and survival of 70 patients with poorly differentiated colorectal cancer were analyzed retrospectively. Chromogranin A and synaptophysin were used as neuroendocrine markers. Patients were followed-up for more than 3 years or un...

Pulmonary and digestive neuroendocrine tumors (NETs) are a group of neoplasms whose incidence and prevalence has been constantly increasing over the last years thanks to the significant improvements in instrumental diagnostic techniques. Because NETs are extremely heterogeneous a correct histopathological diagnosis is essential for appropriate treatment. More specifically, the histopathological...

Pancreatic cancer is classified as ductal, acinar, neuroendocrine carcinoma or pancreatoblastoma. Ductal and acinar cells derive from exocrine glands and neuroendocrine cells from endocrine glands; however, mixed acinar-neuroendocrine-ductal carcinoma has different histological carcinomas coexisting within a nodule. The mixed pancreatic carcinoma forms from different developmental origins and t...
