Overview
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.
Description
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
Eligibility
Inclusion Criteria:
- This study will enroll approximately 60 participants diagnosed with either MPNST or neurofibroma who are undergoing surgical resection of an MPNST or neurofibroma as part of their standard of care.
- Age ≥ 1 years. Individuals younger than 18 years old will be included. For patients of age \< 18 years, both parents' signatures will be requested.
- Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension as ≥10 mm (≥1 cm) with CT scan, MRI, or calipers by clinical exam.
- Recurrent or primary disease.
- Patients who are \> 18 years should have the ability to understand and the willingness to sign a written informed consent document.
- English and non-English speaking patients.
Exclusion Criteria:
- Adult patients with cognitive impairment requiring a legally authorized representative for consent.
- Patients under age 1 and neonates.
- Patients who are pregnant and undergoing surgery for MPNST are not eligible.
