In an early-phase clinical trial of a new oral drug, selumetinib, children with the common genetic disorder neurofibromatosis type 1 (NF1) and plexiform neurofibromas, tumors of the peripheral nerves, tolerated selumetinib and, in most cases, responded to it with tumor shrinkage. NF1 affects 1 in 3,000 people. The study results appeared Dec. 29, 2016, in the New England Journal of Medicine [1].
MIA is a Potential Biomarker for NF1 Tumor Load
Neurofibromatosis type 1 is a genetic condition that can cause tumors to form on nerves under the skin. Since these tumors can become malignant, it is important to monitor their growth closely and detect signs of malignant transformation as early as possible. However, the only way to currently detect them is with an MRI scan. New research published in BioMed Central’s open access journal BMC Medicine shows that a simple blood test for the protein melanoma-inhibitory activity (MIA) may be used to indicate the presence of neurofibromas even if they cannot be seen [1].
