HOW ARE NF1 PLEXIFORM NEUROFIBROMAS (PN) TREATED?

Which doctors and healthcare specialists treat pediatric NF1 plexiform neurofibromas (PN)?

NF1 plexiform neurofibromas are usually treated by a team of healthcare specialists, including neuro-oncologists, oncologists, neurologists, geneticists, surgeons, and others who specialize in treating symptoms related to this disease.

The location and symptoms of your child’s plexiform neurofibromas will help determine which doctors are best to see for treatment.

Why can’t some NF1 plexiform neurofibromas (PN) be completely removed by surgery?

Surgery for NF1 plexiform neurofibromas may not be recommended by your child’s healthcare provider. One reason is plexiform neurofibromas may be closely intertwined with critical nerves, many blood vessels, and located near major organs. Also, PN may not be completely removed by surgery.

Are there any other ways to treat NF1 plexiform neurofibromas (PN)?

Your child’s doctor may prescribe therapies or medicines to help relieve symptoms of NF1 plexiform neurofibromas (PN).

Before Koselugo, there was no FDA-approved medication proven to reduce the size of NF1 plexiform neurofibromas (PN).
Ask your child’s doctor about Koselugo—a prescription treatment for NF1 PN patients who have symptomatic, inoperable plexiform neurofibromas. What is Koselugo?

WHAT ARE SOME WAYS FAMILIES CAN NAVIGATE NF1 PN?

Plexiform neurofibromas (PN) can cause a lot of uncertainty. Creating daily routines for children can help them feel secure and give them a positive sense of control.

Building a supportive home environment in which all family members are treated equally with respect and acceptance can benefit not only the child with NF1 plexiform neurofibromas, but also siblings, who may feel they’re getting less attention.

Making the transition from childhood to teenage years can be especially difficult when living with NF1 PN. Helping your child gradually take more control of their health care, medications, and treatment decisions can encourage responsibility and help them feel empowered.
