Abstract
Background
Long-term results for adult patients who underwent surgery for paediatric brain tumours in the first year of life have not been reported.
Methods
We performed a retrospective study on surgical morbidity, mortality rate, academic achievement and/or work participation in patients who underwent primary tumour resection for a brain tumour as infants in the period from 1973 to 1998. Gross motor function and activities of daily life were scored according to the Barthel Index.
Findings
Thirty-four consecutive children were included. No patient was lost to follow-up. Twenty-two children (65%) underwent gross total resection (GTR), 10 had subtotal resections (STR) and 2 had only partial resection during primary surgery. Nine children were additionally surgically treated for hydrocephalus (HC), many of them with repeat operations for shunt malfunction during follow-up. Three children died within 30 days following GTR of highly vascular tumours. Seventeen (50%) of the infants had high-grade tumours with 1-month, 1-year and 20-year survival figures of 88, 30 and 30%. The corresponding figures for 17 patients treated for low-grade tumours were 94%, 88% and 88%, respectively. Seventeen patients (50%) are still alive as adult long-term survivors at median age of 29 years (range 20 to 43 years). Three died after 29, 30 and 41 years, respectively. At the latest follow-up, 16 out of 17 long-term survivors have a Barthel Index (BI) of 100, while the remaining one has a BI of 40. Two long-term survivors of a high-grade tumour treated 30 and 35 years ago are severely handicapped and have no working capacity. The 15 long-term survivors after treatment for a low-grade tumour are all in daily activity as students (4), in part-time work (3) or full-time work (8).
Conclusion
A brain tumour occurring in the first year of life is a serious threat to the patient and the family, particularly in case of high-grade tumours. In our small cohort, the results from long-term survivors of high-grade tumour group are depressing and confirm the deleterious effect of radiotherapy given to infants decades ago. The infants with low-grade tumours who could be treated with surgical resection without any adjuvant therapy show a good clinical outcome as adults. For parents of these latter patients, the results are far better than feared in advance.
