SPIN-03 PROFILE OF MALIGNANT SPINAL CORD COMPRESSION AMONG CHILDREN AT A SINGLE CENTRE IN JOHANNESBURG, SOUTH AFRICA

Abstract

Abstract OBJECTIVE Malignant spinal cord compression (MSCC) in children can lead to permanent neurological deficits and therefore warrants urgent referral, prompt diagnosis and treatment. There is limited data on paediatric MSCC in Sub-Saharan Africa. The objective was to assess the characteristics, aetiology, clinical presentation, treatment and long-term outcomes of MSCC. METHODS Records of 23 patients with MSCC were retrospectively assessed over a 15-year period (2008-2023) at Charlotte Maxeke Johannesburg Academic Hospital in Johannesburg, South Africa. RESULTS The median age of MSCC diagnosis was four years (range: 5 months to 15 years). The median interval between symptom onset and confirmed diagnosis was three months (1 week to 20 months). MSCC’s leading causes were central nervous system tumours (30%), lymphomas (22%), sarcomas (17%), germ cell tumours (9%), teratoid tumours (9%), neuroblastomas (9%) and leukaemias (4%). Commonest presenting symptoms were motor deficits (96%), pain (35%) and sphincter dysfunction (22%). Magnetic resonance imaging (MRI) of the spine was diagnostic in all cases. The primary tumour was managed using a multimodality approach: 70% underwent neurosurgical intervention and 39% received radiotherapy. The median follow-up duration was two years (1 month to 15 years). There were six deaths (two cases of ependymoma and a case each of glioblastoma multiforme, alveolar rhabdomyosarcoma, acute lymphoblastic leukaemia and Burkitt lymphoma) at a median interval of 4.5 months from diagnosis (1 month to 2 years). The commonest long-term sequelae were motor deficits (52%) and sphincter dysfunction (26%) and 22% of patients were asymptomatic. CONCLUSION We documented longer diagnostic delays than published in the literature and recommend increased awareness and rapid referral to decrease permanent sequelae. Patients presenting with new-onset neurological deficits suggestive of MSCC should have urgent radiological imaging; preferably MRI, followed by prompt referral to a specialised centre with an experienced multidisciplinary team.
