Cytogenetics of tumors of the central nervous system: a case study and review of the literature

The introduction of cytogenetic techniques, especially chromosome banding techniques, has facilitated a more detailed study of the chromosomal basis of hematological malignancies and solid tumours. With the advent of molecular cell biology many new insights have been gained into the pathogenetic mechanisms of cancer. With G banding technique we have studied chromosomal aberrations of 174 tumours of the Central Nervous System in adults and the results obtained have been compared with the literature data.
