Tumors of endocrine glands

Research output: Chapter in Book/Report/Conference proceedingBook chapter


Cytogenetic information is available on roughly 600 neoplasms originating from the thyroid, parathyroid, pituitary, and adrenal glands; from the thymus; and from the endocrine pancreas. Trisomy 7 is found in 30% of adenomas with clonal cytogenetic aberrations. In both the benign and malignant tumors, a combination of gains of or from chromosomes 5, 7, 12, 17, 19, and 20 was observed. Almost all pituitary tumors arise from the adenohypophysis and are benign adenomas; carcinomas are very rare. The clinical heterogeneity of Neuroblastoma (NB) is well reflected by its cytogenetic and genomic features. Clonal chromosome abnormalities were reported in adrenocortical adenomas. Chromosome banding studies have detected cytogenetic aberrations in adrenocortical carcinomas. Clonal chromosome abnormalities have been reported in several thymomas, usually as part of near-diploid karyotypes as well as in a few thymic carcinomas. The use of comparative genomic hybridization (CGH)-based techniques may improve thymoma subtyping.
