The Management of Childhood Intracranial Tumours and the Role of the Ophthalmologist.

ABSTRACT: OBJECTIVE:This study looked at a single paediatric neuro-oncology centre's experience of childhood intracranial tumours seen in the ophthalmology clinic over an approximately five-year period. This was used to analyse the role of the ophthalmologist in their long term follow up. METHODS:A database was compiled of all children discussed at the neuro-oncology multi-disciplinary team (MDT) meeting between January 2012 and April 2017. All children who had an intracranial tumour determined by histology or suspected on neuro-imaging, who had also been seen in the ophthalmology clinic, were included. A retrospective case review was performed to create a record for each child. RESULTS:The database contained 129 children of which 82 (64%) were boys and 47 (36%) were girls. Of these 89 (69%) had a histological diagnosis and 40 (31%) had a tumour suspected on neuroimaging. The most common tumour locations were the posterior fossa (n = 54, 42%), diencephalon (n = 20, 16%) and the visual pathways (n = 17, 13%). Papilloedema at first presentation was only found in 39 (30%) children. The most common other neuro-ophthalmic manifestations were non-paralytic strabismus (n=33), sixth nerve palsy (n=19) and seventh nerve palsy (n=12). Non-paralytic strabismus was a presenting symptom in only one case. There were 13 ophthalmic surgical procedures required for these children, the most common being strabismus surgery. CONCLUSION:We report the types and locations of paediatric intracranial tumours seen in the ophthalmology clinic as well as their neuro-ophthalmic manifestations. Only 30% presented with papilloedema and approximately 10% required an ophthalmic surgical procedure.

Project description:BackgroundChildren are more susceptible to radiation-induced damage than adults, but little research has compared the risk of cancer after exposure to radiation during computed tomography (CT) among children at different ages. We aimed to explore the risk of intracranial tumours, leukemia or lymphoma among children, adolescents and young adults (aged < 25 yr) after radiation exposure from CT at or before the age of 18 years.MethodsWe conducted a nested, population-based case-control study using data from Taiwan's publicly funded health care system. We identified participants younger than 25 years with newly diagnosed intracranial tumours, leukemia or lymphoma, from Jan. 1, 2000, to Dec. 31, 2013. We assigned 10 non-cancer controls for each case, matching by sex, date of birth and day of entry to the cohort. We considered CT scans received at or before the age of 18 years and 3 or more years before the index date (the date of cancer diagnosis for cases) as exposure. We used conditional logistic regression models and incidence rate ratios (IRRs) to estimate the relationship between risk of these cancers and CT radiation exposure.ResultsWe identified 7807 cases and matched to 78 057 controls. Compared with no exposure, exposure to a single pediatric CT scan did not increase risk of intracranial tumours, leukemia or lymphoma. However, participants exposed to 4 or more CT scans had an elevated incidence (IRR 2.30, 95% confidence interval 1.43-3.71) of one of the cancer outcomes of interest. Receiving 4 or more CT scans at or before 6 years of age was associated with the highest risks of cancer, followed by ages 7-12 years and 13-18 years (p for trend < 0.001).InterpretationExposure to a single CT scan was not associated with increased risks of subsequent intracranial tumours, leukemia or lymphoma among children; however, we observed increased cancer risks among those with 4 or more CT scans, especially among younger children. Although these cancers are uncommon, the findings of this study underscore the importance of prudent use of CT in the pediatric population.
