Presentation and outcomes of paediatric craniopharyngioma in the west of Scotland: a 25 year experience.

PURPOSE: Craniopharyngiomas can be aggressive leading to significant complications and morbidity. It is not clear whether there are any predictive factors for incidence or outcomes. Our aim was therefore to record the incidence, presentation, characteristics and progression of paediatric craniopharyngiomas in the West of Scotland. METHOD: Retrospective case note review for children diagnosed with paediatric craniopharyngiomas at the Royal Hospital for Children Glasgow, from 1995 to 2021 was conducted. All analyses were conducted using GraphPad Prism 9.4.0. RESULTS: Of 21 patients diagnosed with craniopharyngiomas, the most common presenting symptoms were headaches (17/21, 81%); visual impairment (13/21, 62%); vomiting (9/21, 43%) and growth failure (7/21, 33%). Seventeen (81%) patients underwent hydrocephalus and/or resection surgery within 3 months of diagnosis, usually within the first 2 weeks (13/21, 62%). Subtotal resection surgeries were performed in 71% of patients, and median time between subsequent resection surgeries for tumour recurrence was 4 years (0,11). BMI SDS increased at 5 year follow-up (p = 0.021) with 43% being obese (BMI > + 2SD). More patients acquired hypopituitarism post-operatively (14/16, 88%) compared to pre-operatively (4/15, 27%). A greater incidence of craniopharyngiomas were reported in more affluent areas (10/21, 48%) (SIMD score 8-10) compared to more deprived areas (6/10, 29%) (SIMD score 1-3). Five patients (24%) died with a median time between diagnosis and death of 9 years (6,13). CONCLUSION: Over 25 years the management of craniopharyngioma has changed substantially. Co-morbidities such as obesity are difficult to manage post-operatively and mortality risk can be up to 25% according to our cohort.

Volume reduction with surgery for ICH: when is it effective? Analysis of the CT scans from the STICH II trial.

BACKGROUND: The surgical trial of lobar intracerebral haemorrhage (STICH II) was a randomised controlled trial evaluating early surgical removal of a clot. This paper investigates volume change in both arms of the trial with respect to Extended Glasgow Outcome Scale (GOSE) groups. METHODS: Patients randomised into STICH II had an initial diagnostic CT and a second CT 5 days after randomisation. Each scan was anonymously assessed by at least two central readers. An analysis of agreement between the two readers was conducted using kappa tests and intraclass correlation. The change in volume in both the early surgery (ES) and the initial conservative treatment (ICT) arms were analysed with respect to the six-month GOSE outcome. RESULTS: Of the 597 patients randomised in the trial there were 582 pre-randomisation scans and 566 5-day scans available for analysis of agreement. There was good agreement between the assessors for the radiological inclusion criteria including volume (ICC = 0.87) and this was better than the agreement between the assessor and local investigator (ICC = 0.73). There were 526 patients with two scans available for analysis of change in volume measurement. The median percentage change in volume for the ES group was a reduction of 92.4% (IQR 75.6%, 99.0%) while for the ICT group, in which some cases crossed over to delayed surgery, it was only 5.7% (IQR 16.4% increase, 29.5% reduction). ES patients with almost complete removal (99-100%) had the best outcome with only 30% dead or lower severely disabled. For the ICT group outcome was related to the final volume: the smaller the final volume the better the outcome. CONCLUSIONS: This analysis provides evidence for central assessments of scans in exploratory analyses and further information regarding the potential advantage of early and more complete clot removal on outcome in ICH and should inform the planning of future trials.Clinical trials registration: ISRCTN22153967.
