PDOC-08 THE CLINICAL CHARACTERISTICS OF CHILDREN WITH CRANIOPHARYNGIOMA AND THEIR MANAGEMENT IN UGANDA: A RETROSPECTIVE REVIEW Open Access

Craniopharyngiomas are benign brain tumors that mostly arise in the sellar/suprasellar region. Histologically though benign, these tumors can locally infiltrate with involvement of surrounding structures. They have a 5-year survival rate of above 80% in High Income Countries (HIC). Craniopharyngioma management includes surgery, radiotherapy and intracystic treatments, which requires a multi-disciplinary team. The morbidity associated with treatment must be weighed against tumor recurrence and quality of life after treatment. Endocrine deficiencies, especially growth hormone deficiency and visual deficits are common presenting features.

To describe the clinical characteristics and management of children with craniopharyngioma managed at Mulago National Referral Hospital from March 2019 to December 2023. METHODOLOGY: A retrospective descriptive study was conducted among patients< 18 years of age, admitted to the Mulago National Referral Hospital (MNRH) from March 2019 to December 2023 with a radiological diagnosis of a craniopharyngioma.

A total of 151 children with a diagnosis of a brain tumor during this period were identified and of these 40 (26%) were diagnosed with craniopharyngioma. The median age was 8.4 years and 22 (55%) were males. Only 2 children had maximal safe resection (sub-total resection), one of whom later received adjuvant external beam radiotherapy. Thirty-eight patients had insertion of Ommaya reservoirs as their tumors were predominantly cystic. Two patients received intracystic bleomycin and 11 received radical external beam radiotherapy. Twenty-seven patients had no additional therapy after Ommaya reservoir placement. Fifteen (39%) of the patients had endocrine deficits with hypothyroidism, hypocortisolism and growth hormone deficiency being the most common. The median follow-up time was 1.45 years. The overall survival was 67.5%, 95%CI (42.5-83.5).

Management of patients with craniopharyngioma in Uganda is mostly conservative with the aim of intervention to preserve quality of life. Limited access to radiation therapy contributed to the poorer survival compared to HIC.
