The Neurofibromatosis-associated Tumor Biobank

Not yet recruiting

• Conditions: Neurofibromatoses

• Registration Number: NCT03359304
• Lead Sponsor: Ren tingting

Brief Summary

Neurofibromatosis-associated Tumor is very rare bone tumor. The investigator set up the biobank to ensure every patient has the chance to participate in future research

Detailed Description

Samples of blood and other stored material such as slides,frozen tissues or leftover diagnostic material.

Questionnaire information, including health history, growth and development, physical activity and family medical history information.

If patients have been diagnosed with a neurofibromatosis-associated tumor or another condition the investigator is interested in， the investigator will ask the patient to release medical record information relating to diagnosis and treatment of neurofibromatosis-associated tumor, other cancers, blood disorders, and similar conditions.
