An observational study in Neurofibromas and MPNST, sponsored by M.D. Anderson Cancer Center. Recruiting at 1 site in United States. Open to participants aged 1 Year and older. Per ClinicalTrials.gov, last updated 2026-09-18.
Sponsored by M.D. Anderson Cancer Center · Observational
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.
Primary Objectives:
Aim 1. Determine the metabolite and lipid profiles of MPNST, neurofibroma, and nerve tissues
Aim 2. Validate the handheld mass spectrometry device (MSPen-Orbitrap system) for MPNST and neurofibroma diagnosis and for intraoperative surgical margin evaluation

Compared within Neurofibrosarcoma, this study's primary condition as ClinicalTrials.gg classifies it; the registry's first condition term is Neurofibroma. The counts are of registry records indexed under each term, refreshed daily. How we classify →
For Aim 1: 100 neurofibromas and 104 MPNST snap-frozen, clinically and pathologically annotated samples have been identified. These have been collected under protocol LAB06-0851.
For Aim 2: We will evaluate the technology in the OR and enable surgeons to collect molecular data from a cohort of 60 patients undergoing resection of suspected or diagnosis of MPNST/neurofibroma (protocol: 2019-1118).

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.
The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
