Recent evidence indicates that cyclic nucleotides are of importance for general and neurosurgical oncology, especially with respect to the contact-inhibition mechanisms and tumour cell growth. This preliminary report deals with the CSF levels of c-AMP and c-GMP in primary neoplasms in children and to problems related to the blood-brain barrier. Some cases of medulloblastoma were studied as well as a few cases of brain stem glioma and cystic astrocytoma. The importance of some rather unusual findings seems undebatable, i.e., the marked increase in c-GMP values usually observed in medulloblastoma and the decrease of c-AMP, that is fairly common in all malignant neoplasms. The main changes in the c-AMP/c-GMP ratio are also discussed.

Abstract
Recent evidence indicates that cyclic nucleotides are of importance for general and neurosurgical oncology, especially with respect to the contact-inhibition mechanisms and tumour cell growth. This preliminary report deals with the CSF levels of c-AMP and c-GMP in primary neoplasms in children and to problems related to the blood-brain barrier. Some cases of medulloblastoma were studied as well as a few cases of brain stem glioma and cystic astrocytoma. The importance of some rather unusual findings seems undebatable, i.e., the marked increase in c-GMP values usually observed in medulloblastoma and the decrease of c-AMP, that is fairly common in all malignant neoplasms. The main changes in the c-AMP/c-GMP ratio are also discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
