Treatment of Plexiform Neurofibromas: Current Perspectives on Surgery and Medical Treatment

Plexiform neurofibromas (PNFs), a critical clinical feature of neurofibromatosis type 1, mainly involve several peripheral nerve branches and extend widely, including the skin and bones and the internal organs. Determining the appropriate treatment is difficult. Additionally, they possess the potential to develop into malignant peripheral nerve sheath tumors (MPNSTs), which are linked to an extremely poor prognosis. Active treatment is critical in patients with symptoms or progressive tumor growth, especially in pediatric cases. Surgery remains the standard treatment for managing PNFs and MPNSTs; however, it has often demonstrated insufficient results because of its wide distribution and the frequent involvement of major organs. Selumetinib, a recently approved mitogen-activated protein kinase kinase inhibitor, is gaining traction in treating inoperable PNFs in children.
