Brain tumours in infants. Preferred treatment options.
Since the advent of CT scan and MRI, the diagnosis of neonatal infantile brain tumours and related diseases is more easily accomplished; their rarity is reflected in the small number of cases reported. Astrocytomas and teratomas are the most common oncotypes in infants and particularly in neonates. Surgical mortality rates are not high and have decreased because of the advances of diagnosis and improvements in treatment. However, the survival rates are disappointing. Follow-up shows little improvement in last 2 decades. Adjuvant therapy is still a problem; radiotherapy gives a small percentage of favourable later neuropsychological results. Postoperative chemotherapy added to maximal surgical resection and delayed irradiation may prolong survival with only minimal short term neurotoxicity in very young children with malignant tumours. Different protocols of chemotherapy are suggested but still not definitely accepted. Radical surgery seems to have a higher chance of success in neonates than infants and remains the less aggressive means; in low grade gliomas after total removal it may be preferable to perform a second operation if the tumour recurs and withhold irradiation and chemotherapy until after 3 years of age.
