The pathogenesis of adrenal tumors is still not fully elucidated and the treatment options for malignant tumors are poor. The current study investigates different aspects of the pathogenes...
GI tract including pancreas is the one of most common primary sites of neuroendocrine tumors. Current grading of neuroendocrine tumors are based on the 2010 WHO classification. This classi...
This is a 4-part, open-label, Phase 1/1b, dose escalation study in pediatric patients with relapsed refractory solid tumors; 2) primary CNS tumors; 3) neuroblastoma; and 4) non-neuroblasto...
This study is a Phase I study using vinblastine and sirolimus in patients with relapsed solid tumors including selected brain tumors and lymphoma. The investigators hypothesis is that the ...
RATIONALE: Drugs used in chemotherapy, such as valproic acid, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Valpr...
Pituitary tumors are common, well-described skull base tumors of sellar origin. However, there are reports of rare ectopic pituitary tumors that are found exclusively outside of the sella turcica. Ect...
Brain tumors are found in 1-3% of children with newly onset of seizures. Understanding the impact of seizures on pediatric brain tumors and factors between seizures and brain tumors are crucial. This ...
Cardiac tumors are uncommon, occurring in less than one percent of the population, and are comprised of numerous tumor types. Management of certain tumors types such as sarcoma have evolved and improv...
The RNA-binding protein HuC/D displays a neuron-specific expression and is involved in neuronal differentiation and the maintenance of the nervous system. Here we investigated the diagnostic value of ...
Lid tumors show a heterogenous clinical spectrum. Tumors which display some criteria of malignancy may histologically be diagnosed as inflammatory lesions without any neoplastic component. In contrast...
A group of malignant tumors of the nervous system that feature primitive cells with elements of neuronal and/or glial differentiation. Use of this term is limited by some authors to central nervous system tumors and others include neoplasms of similar origin which arise extracranially (i.e., NEUROECTODERMAL TUMORS, PRIMITIVE, PERIPHERAL). This term is also occasionally used as a synonym for MEDULLOBLASTOMA. In general, these tumors arise in the first decade of life and tend to be highly malignant. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, p2059)
Tumors in any part of the heart. They include primary cardiac tumors and metastatic tumors to the heart. Their interference with normal cardiac functions can cause a wide variety of symptoms including HEART FAILURE; CARDIAC ARRHYTHMIAS; or EMBOLISM.
Tumors whose cells possess secretory granules and originate from the neuroectoderm, i.e., the cells of the ectoblast or epiblast that program the neuroendocrine system. Common properties across most neuroendocrine tumors include ectopic hormone production (often via APUD CELLS), the presence of tumor-associated antigens, and isozyme composition.
A family of mesenchymal tumors composed of histologically and immunohistochemically distinctive perivascular epithelioid cells. These cells do not have a normal anatomic homolog. (From Fletcher CDM, et. al., World Health Organization Classification of Tumors: Pathology and Genetics of Tumors of Soft Tissue and Bone, 2002).
Tumors or cancer of the PANCREAS. Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).
