Brief summary
ASCEND-BRAIN is a prospective, observational study aimed at early-detection of intracranial tumors by combined assays of cfDNA methylation and other biomarkers. The study will enroll approximately 358 participants including intracranial malignant tumors, patients with benign disorders of central nervous system and healthy participants.

Eligibility
Inclusion criteria
for Cancer Participants: * Age 40-75 years * Ability to provide a written informed consent * Pathologically confirmed diagnosis or highly suspicious cases of intracranial malignant tumors * No prior or ongoing anti-cancer treatment (local or systematic) prior to study blood draw Inclusion Criteria for Benign Disease Participants: * Age 40-75 years * Ability to provide a written informed consent * Pathologically confirmed diagnosis or highly suspicious cases with benign disorders of central nervous system * No prior or ongoing radical treatment of the benign disorders of central nervous system prior to study blood draw Inclusion Criteria for Healthy Participants * Age 40-75 years * Ability to provide a written informed consent * No cancer-related symptoms or other uncomfortable symptoms prior to study blood draw
Exclusion criteria
for All Participants: * Insufficient qualified blood samples * Recipient of organ transplant or prior non-autologous (allogeneic) bone marrow or stem cell transplant * Recipient of blood transfusion within 7 days prior to blood draw * Recipient of anti-tumor drugs to treat non-cancer diseases within 30 days prior to blood draw, such as rheumatic drugs (methotrexate, cyclophosphamide, or azathioprine), or endocrine drugs (tamoxifen) Additional
