Interferon-alpha for Unresectable Progressive and Symptomatic Plexiform Neurofibromas

Abstract

Neurofibromas are the most common manifestations of neurofibromatosis type-1. They occasionally cause pain or progressive loss of function due to nerve compression. Optimal treatment approach is still challenging and the current treatment results are not satisfactory. Four cases of plexiform neurofibromas with various clinical presentations and an addendum to a previously published report on a patient who had relief from pain and/or regression of tumor volume after treatment with interferon-alpha 2a are presented.
