Transformation of Plexiform Neurofibromas to Malignant Peripheral Nerve Sheath Tumors in Neurofibromatosis Type 1

Background:\<TAB\> \- Many people with neurofibromatosis type 1 (NF1) get tumors of the nervous system. Finding malignant tumors early is important for removing them. Researchers want to find ways of doing this with scans and genetic testing. Objectives: \- To learn more about neurofibromatosis type 1. Eligibility: \- People age 10 and older with NF1 who have a benign tumor or have had a malignant one. Design: * Participants will be screened in another study with medical history, physical exam, and urine and blood tests. They will have a magnetic resonance imaging (MRI) scan. * MRI: Participants will lie on a table that slides into a metal cylinder. They will be in the scanner for 60 90 minutes, lying still for 15 minutes at a time. Participants will get earplugs for the loud sounds. They will get a contrast agent (dye) through a thin plastic tube (catheter) inserted in an arm vein. * As part of their regular care, participants will have: * FDG-PET/CT scan. They will get radioactive glucose (sugar) through a catheter in an arm vein. * \[18F\]-FLT-PET/CT scan. This is like the FDG scan but with a different radioactive chemical. * Biopsy. A piece of tumor tissue is removed with a needle. A piece of tissue from a previous biopsy may also be studied. * Participants may have genetic testing. Blood will be taken. It will be tested along with biopsy samples. Researchers will explain the risks and procedures. They may notify participants if testing shows health problems. * After this study, participants will continue their regular cancer care.

A Study of Selinexor in People With Wilms Tumors and Other Solid Tumors

The purpose of this study is to find out whether selinexor is an effective treatment for people who have a relapsed/refractory Wilms tumor, rhabdoid tumor, MPNST, BCOR-driven sarcoma, or another solid tumor that makes a higher than normal amount of XPO1 or has genetic changes that increase the activity of XP01.

DoD Award NF230020 Identification of Metabolic Markers and Statistical Prediction of MPNST for Rapid Diagnosis and Assessment of Surgical Margins

The goal of this clinical research study is to learn if a handheld Mass Spectrometry device (MasSpec Pen) can accurately distinguish between masses, neurofibroma, and normal tissue during surgery.

Trial of Selumetinib and Bromodomain Inhibitor With Durvalumab for Sarcomas

A multi-institutional open-label phase 1/2 trial of selumetinib in combination with ZEN-3694 and durvalumab in refractory/unresectable sarcomas including MPNST. The phase 1 portion will be separated in two parts and will be open to all patients with refractory/relapsed sarcomas. The phase 2 portion will be for patients with refractory/unresectable NF1-associated MPNST.
