BACKGROUND Nonfunctional pancreatic neuroendocrine tumors (NF-PNETs) are rare tumors with highly variable outcome. Current guidelines recommend surveillance for small tumors (≤ 2 cm), but a scientific basis for such recommendation is scarce. METHODS Patients who underwent surgery for NF-PNET during 2001-2013 were identified from a prospectively maintained database and reviewed retrospectively...

BACKGROUND Although the relationship between non-O blood types and the risk of exocrine pancreatic cancer has been demonstrated, the association between ABO blood types and sporadic pancreatic neuroendocrine tumor (PNET) has not been reported thus far. METHODS This hospital-based, case-control study included 387 patients with PNET and 542 age- and sex-matched controls. Unconditional multivari...

A recent study found that a majority of pediatric patients diagnosed with central nervous system primitive neuroectodermal tumors may have other types of central nervous system cancers instead. Researchers also concluded that these rare brain tumors fall into four distinct molecular subtypes. The findings may lead to more accurate diagnoses and more-tailored treatment plans.

Very few cases have been reported the literature they had a very different presentation aggressive behavior. Case We present case of young 23-year-old male who presented with complaints pain left lumbar region abdomen since 8 months hematuria off on. CT scan was done which revealed...

Primary intraspinal primitive neuroectodermal tumor (PNET) is a type of round cell malignant which reported only above 100 in literature. We report case Dorsal Spine Primitive Neuroectodermal Tumor (P.N.E.T) Presenting with Features Pott’s Spine, & discuss its pathological features, radiology, and treatment options.

OBJECTIVE The aim of this study was to evaluate efficacy and safety of everolimus in patients with pancreatic neuroendocrine tumors (pNET) by prior chemotherapy use in the RAD001 in Advanced Neuroendocrine Tumors, Third Trial (RADIANT-3). METHODS Patients with advanced, progressive, low- or intermediate-grade pNET were prospectively stratified by prior chemotherapy use and World Health Organi...
