This study will analyze DNA samples to determine associations between maternal and offspring genetic factors and pediatric brain tumor development in children with Neurofibromatosis Type 1. Participating families (mother, father, child) will be asked to complete a short questionnaire and provide DNA samples (either saliva or blood). The information gained from your participation may one day help doctors develop strategies to reduce brain tumor risk in individuals with NF1. Please note: there is no therapy associated with this study.
Background: - Serious illnesses like cancer or Neurofibromatosis Type 1 (NF1), can cause high levels of stress in a family. When a child is diagnosed with cancer or NF1, parents face numerous stressors, each of which can strain relationships. Many parents struggle to effectively cope with the changes in parenting roles that often accompany treatment of childhood cancer or NF1. How parents cope with this stress can influence whether the relationship is strengthened or weakened. Stress levels can also affect the care of the child who has cancer or NF1. Researchers want to better understand the critical time points and events during the child s treatment when the relationship becomes most stressed and/or strengthened. Objectives: - To study how stress affects the relationship between parents who have a child with cancer or Neurofibromatosis Type 1 (NF1). Eligibility: - Parents of a child (between 1 and 24 years of age) who has been diagnosed with cancer or NF1. - Participants must have been in a partnership at the time the child was diagnosed with cancer or NF1. At least one of the parents must be a biological or legal parent of the child. Design: - Participants will fill out a questionnaire either online or by paper and pencil. It will take about 20 minutes to complete. The questions ask about the experience of dealing with a child s cancer OR NF1 diagnosis and how it affects participants relationship with their spouse/partner. - Some participants will also have an in-depth interview. It will last about an hour. It will ask further questions about the cancer OR NF1 diagnosis and treatment and its effect on the relationship. - Treatment will not be provided as part of this study.
GENERAL OBJECTIVE The general objective is to assess the safety and efficacy of photodynamic therapy (PDT) in the treatment of neurofibromatosis 1 (NF1) tumors in the skin. SPECIFIC OBJECTIVE This is a light dose escalation pilot study to determine the safety and efficacy of PDT using 5-aminolevulinic acid (ALA) and 633 nm light in the treatment of benign dermal neurofibromas. Specifically, the primary goal of the current study is to determine the maximum tolerable light doses that can be administered to subjects undergoing topical photoillumination photodynamic therapy with standard application of Levulan Kerastick (ALA) for Topical Solution.
Thanks to the investigators previous study the investigators demonstrated the influence of modifying genes in the phenotypic expression of neurofibromatosis 1 (Hum Mol Genet. 2009; 18 (15) :2768-78). Indeed, analysis of the intra-and inter-family variability performed using the investigators phenotype/genotype database demonstrated a strong genetic component for most clinical features. The investigators results suggest the involvement of genetic factors, not related to the NF1 gene, the modifiers. The objective of this project is to identify the modifiers involved in the variability of clinical expression of NF1. The investigators will focus in particular variants involved in the development and progression of neurofibromas.
Background: - Assessing pain levels is important to improve treatments for different illnesses. Most pain rating scales are used to determine pain levels in adults. Pain is also a common symptom among children who have cancer. Those who have genetic conditions that may lead to cancer may also have pain symptoms. However, the pain scales used for adults have not been fully tested in children and young adults. As a result, they may not be as accurate. Researchers want to test pain rating scales in children and young adults who have cancer and genetic conditions that can lead to cancer. Objectives: - To study the effectiveness of pain rating scales given to children and adults with Sickle Cell Disease (SCD),cancer, and related genetic conditions. Eligibility: - Adults 18 and 34 years of age and older who have SCD, cancer, or other genetic conditions that can lead to cancer. Design: - Participants with SCD, cancer or related genetic conditions will fill out four questionnaires. These questionnaires will ask about pain levels and how much pain interferes with daily life. - Pain treatments will not be provided as part of this study.
Background: - Neurofibromatosis type 1 (NF1) is a genetic disorder that can cause frequent and significant pain. This pain can have a severe impact on a person s quality of life. - Acceptance and Commitment Therapy (ACT) is a new type of therapy that may help people manage pain. It teaches behavioral techniques that can be used to change how people react to pain. ACT may help people with NF1 cope better with the pain associated with the disorder. Researchers want to test ACT techniques to see if they can improve coping in people with NF1 pain. Objectives: - To see if ACT can help treat chronic pain in adolescents and young adults who have NF1. Eligibility: - Adolescents and young adults between 12 and 21 years of age who have chronic pain associated with NF1. Design: - Participants will be screened with a physical exam and medical history. They will also complete a set of questionnaires about their pain levels, quality of life, and medications that they are taking. - Participants will take part in a training workshop for ACT. It will consist of three 2-hour sessions over 2 consecutive days. The workshop will teach techniques for setting goals that reflect personal values, and changing the focus from pain avoidance to pain management. There will be practice exercises between each session. - At the end of the workshop, participants will receive a workbook with the exercises to continue to practice at home. Participants will be encouraged to spend at least 20 minutes, three times per week, on these practice exercises. - There will be a followup phone call to check on pain management after the workshop. - Three months after the first study visit, participants will complete the study questionnaires again from home. They will provide more information about how they are managing their pain. The questionnaires will be returned by mail in an envelope provided by the study team.
The study will seek to determine whether there is a corresponding deficit in school performance for teenagers with NF1. Secondly, the study seeks to explore the issue of self-esteem in teenagers with NF1.
MicroRNAs are small molecules which have recently been discovered in cells. They are known to be responsible for the normal development of cells and when they are disrupted can contribute to the development of cancer. Many previous studies have been done evaluating the expression of microRNAs in normal tissues as well as in a wide variety of cancers. Recently, microRNAs from tumor cells have been detected circulating in the blood of patients with cancer. This presents a novel opportunity to assess the utility of microRNAs in the blood as an early predictor of cancer as well as a marker of response to therapy. No previous studies have been performed evaluating microRNAs in archived tumor tissue and blood of patients with Neurofibromatosis type 1 (NF-1). The investigators propose a feasibility study to evaluate the presence of microRNAs in archived tumor tissue and the blood of patients with NF-1. If the investigators are able to identify circulating microRNAs in this population of pediatric patients, they will build upon this data in proposing a future study.
This randomized phase II trial studies how well low-dose lenalidomide works compared with high-dose lenalidomide in treating younger patients with juvenile pilocytic astrocytomas or optic nerve pathway gliomas that have come back (recurrent), have not responded to treatment (refractory), or are growing, spreading, or getting worse (progressive). Lenalidomide is classified as an immunomodulatory drug as it boosts the immune system. It has other potential anti-tumor effects, for example, it may stop the growth of tumor cells by blocking blood flow to the tumor. It is not yet known whether low-dose lenalidomide is more or less effective than high-dose lenalidomide in treating patients with juvenile pilocytic astrocytomas or optic nerve pathway gliomas.
