11. Genes and brain tumors
Sammanfattning : Although brain tumors are rare and combined with other nervous system tumors account for ~ 2% of all cancers, they are the second most common type of pediatric cancer. The etiology of brain tumors, known as multifactorial traits, is poorly understood. LÄS MER
12. Small Intestinal Neuroendocrine Tumors : Clinical Studies, Novel Serum Biomarkers and Sensitivity to Cytotoxic and Targeted Agents
Sammanfattning : Small Intestinal Neuroendocrine Tumors (SI-NETs) are indolent neoplasms with an increasing annual incidence of approximately 1/100 000 people. They are often diagnosed at a late stage, restricting treatment efficacy. LÄS MER
13. Genetic studies of endocrine abdominal tumors
Sammanfattning : Pancreatic endocrine tumors (PETs) occur sporadically or in the familial multiple endocrine neoplasia type 1 (MEN1) syndrome, whereas midgut carcinoids are nonfamilial, malignant endocrine tumors of the intestine. For these tumor entities morphological criteria are of limited use for prognostic prediction and selection of treatment. LÄS MER
14. Pathogenetic Mechanisms in Soft Tissue Tumors
Sammanfattning : Soft tissue tumors (STT) constitute a heterogeneous group of tumors that arise in tissues of mesenchymal origin. They are currently classified according to morphology and resemblance to normal tissue into over 100 subtypes. LÄS MER
15. Morphological Features and Mismatch Repair in Colorectal Tumors
Sammanfattning : Corlorectal cancer affects 5% of individuals in the Western world and heredity is estimated to cause at least 10% of the tumors. Defective mismatch repair (MMR) is a tumorigenic mechanism through which about 15% of colorectal cancer develops and this feature characterizes tumors associated with Hereditary Nonpolyposis Colorectal Cancer (HNPCC) or Lynch syndrome.
