Development and Validation of Patient Reported Outcome (PRO) Measures for Individuals With Neurofibromatosis 1 (NF1) and Plexiform Neurofibromas (pNFs)

Background: People with neurofibromatosis 1 (NF1) who have plexiform neurofibromas (pNFs) can have pain that affects their daily lives. This study aims to improve questionnaires that measure their pain, daily living, and physical functioning. Objectives: To examine and improve questionnaires about daily living for people with NF1 and pNFs. Eligibility: People ages 5 and older with NF1 and a pNF Design: Participants will be screened with medical history. This study will have 2 phases. Phase 1 participants will talk about existing pain assessment questionnaires and how pNFs affect their life. They will have group discussions of up to 8 people of a similar age with NF1 and pNFs, or the parents of children with it. These will last about 90 minutes. Children ages 5 to 7 and their parents will have one-on-one meetings instead. These will last about 45 minutes. Discussions will be audiotaped. After the questionnaires have been changed, individual interviews will discuss the new wording, instructions, questions, and electronic format of the new forms. Phase 2 is now complete. Phase 1 participants may be invited to Phase 2. Phase 2 participants will complete the new questionnaires. These may be pen-and-paper or electronic. The questionnaires will take about 30 minutes for adults and teens. Children will work one-on-one with a staff member and may need up to 45 minutes. A small group of participants will be complete the forms twice-in clinic and 1 month later at home. Also, a small group who start a new pain treatment or have a dose increase in their treatment will complete the forms twice-before the treatment change and 1 month later. ...

Neurofibromatosis Type 1 Tumor Early Detection Study

The goal of this observational study is to determine if a liquid biopsy (i.e. blood test) is an effective clinical tool for monitoring the development of malignant peripheral nerve sheath tumor (MPNST) among adults (18 years and older) with Neurofibromatosis Type 1 (NF1), compared to the current standard of care. The main questions it aims to answer are: How effective is liquid biopsy compared to the current standard of care (clinical surveillance and imaging) for early detection of MPNST development among people with NF1? Can liquid biopsy offer a cost-effective method for early detection of MPNST in people with NF1? Also, can liquid biopsy provide earlier detection that potentially leads to better outcomes? Also, can offering liquid biopsy improve access to care for people experiencing barriers to access (such as minority populations or people in rural areas)? At baseline, participants will be asked to: * Complete surveys to provide their demographic and NF1-related health information. * Report whether or not they are experiencing MPNST-related symptoms. * Provide blood samples (15 mL blood total between three tubes, which is approximately one tablespoon). Every six months during the five-year follow-up period, participants will be asked to: * Complete additional surveys to report whether or not they are experiencing MPNST-related symptoms and/or if they have been diagnosed with a new MPNST. * Provide an additional blood sample (10 mL blood total in one tube). If diagnosed with an MPNST by their healthcare provider during the follow-up period, participants will be asked to: * Complete an additional survey regarding their diagnosis and symptoms. * Provide an additional blood sample (10 mL blood in one tube). * In parallel, the study team will request a sample of tumor tissue from the care provider, if available.

HL-085 in Adults With Neurofibromatosis Type 1 (NF1) and Inoperable Plexiform Neurofibromas
