A single center experience in the management of progressive juvenile pilocytic astrocytoma
- View All
BACKGROUND: Juvenile pilocytic astrocytoma (JPA) typically follows an indolent clinical course. The first-line treatment for most JPAs is surgical resection. However, a gross total resection may not be feasible for deep-seated lesions and/or infiltrative tumors, leading to multimodal treatment approaches that may be complicated by patient age and tumor location. Despite the prevalence of pediatric JPAs, there is no single approach to treating progressive disease. METHODS: We investigated the multifaceted management of progressive JPAs through a retrospective analysis of JPAs treated at a single center over an 18-year period (1998-2016). All cases were categorized according to location, whether supratentorial or infratentorial, and for each case we calculated the number of interventions and the time between interventions. RESULTS: We identified a total of 40 JPAs, (11 supratentorial, 29 infratentorial). Total number of interventions among all supratentorial JPA patients was 21 (average 2 interventions/patient). The total number of interventions among infratentorial JPAs was 40 (average 1.4 interventions/patient). CONCLUSIONS: Treatment of progressive JPA is variable and may require numerous surgeries and adjuvant therapies.
