Researchers involved in the cytogenetics and molecular genetics of human tumors will welcome this comprehensive overview of the type of aberrations that chromosome 12 presents in human solid tumors. The authors study the implications for a cytogenetic subtyping of the tumors involved and strategies for identifying the molecular changes which underlie the karyotypic alterations.The aberrations of chromosome 12 which the book deals with are very frequent chromosomal alterations in human tumors occuring in frequent benign mesenchymal tumors, such as uterine leiomyomas and lipomas, and in tumors of epithelial origin, such as pleomorphic adenomas of the salivary glands.
