Brief Summary:
Background:
People with Neurofibromatosis type 1 (NF1) have an increased risk of developing plexiform neurofibromas (PNs). PNs are tumors that form in the tissue. They can form anywhere in the body. They can become visible and cause deformations. Researchers want to see if selumetinib changes how PNs look in people with NF1. They also want to test a rating system for the visibility of these tumors.
Objective:
To see if treatment with selumetinib can improve the appearance of visible PNs in people with NF1, as determined by people who are/are not familiar with NF1.
Eligibility:
People with NF1 who have one or more visible PNs and have been enrolled in study 11C0161 or 08C0079. Clinicians and non-clinicians with and without experience in NF1 are also needed to serve as raters.
Design:
Participants are people with NF1 who had photos taken on study 11C0161 or 08C0079. Raters are people who will evaluate the PNs in the photos. They will rate the tumors on a scale from 1 to 10, from less to most visible.
Participants medical records will be reviewed. Their photos will be shown to 28 raters.
Raters will fill out a survey about their demographics, place of work, and if they are familiar with NF1. They will view sample photos to learn how PNs look and how to rate PNs.
Raters will view photos of PNs taken before and after selumetinib treatment. They will also view photos of PNs that were not treated. They will rate PNs for up to 40 participants. They will have 1-2 sessions. Each session will last 1 hour....

Detailed Description:
Background:
Up to 50% of subjects with Neurofibromatosis Type 1 (NF1) will develop histologically benign plexiform neurofibromas (PN).
One of the most common morbidities associated with PN is a disfigurement that has the potential to pose formidable obstacles to the medical and psychosocial well-being of subjects with NF1.
The phase 2 trial of the MEK inhibitor selumetinib for inoperable PN (NCT01362803) have shown volumetric shrinkage of PN in approximately 74% of subjects with at least one PN morbidity, with most of the responsive tumors decreasing in size by 20-50% volume from baseline. Both trials have completed enrollment and primary study objectives.
In this selumetinib trial, standardized photography of visible PN was performed over time to assess for changes in disfigurement over time. This trial did not include criteria to measure changes in disfigurement and no validated criteria for measurement of PN-related disfigurement exist.
We developed a scale to rate the extent of a disfigurement from NF1 PN and will apply this scale to photographs obtained on the phase II selumetinib trial.
Objective:
To determine if selumetinib treatment is associated with improvement in PN-related disfigurement, as determined by raters reviewing photographs before treatment and just prior to cycle 13 of treatment.
Eligibility:
Four groups of adult raters to rate disfigurement who are not directly involved in the conduct of the selumetinib treatment study (NCT01362803), who are not NIH employees, and can read and write in English.
Design:
-Methods
Photographs of consenting individuals with PN, who may or may not have received selumetinib will be reviewed.
Raters will be presented pre and post treatment photographs of persons who received selumetinib as well as control photographs of persons not receiving selumetinib.
Each rater is presented with the same set of photographs though placement and order may differ.
Each rater will look at photographs of each individual with PN for at least 10 seconds, then with photos still visible, raters will verbally answer a questionnaire.
The rater will be asked questions at the end of the session to assess the feasibility of the questionnaire.
Session will be repeated by some raters approximately six months later on a subset of the photographs.
-Statistical Analysis
In each cohort of raters, for each subject s slide set evaluated at a time point, the mean of the raters scores for each subject will be formed.
For each person with PN that received selumetinib, the paired difference between baseline and pre-cycle 13 of these mean scores will be determined.
For the full set of approximately 35 paired scores, the difference will be assessed for statistical importance by means of a paired t-test, or a Wilcoxon signed rank test.
