Researchers are studying central nervous system (CNS) tumors to gain a better understanding of their characteristics. This observational study collects tissue samples from patients with CNS tumors during surgery and post-mortem to develop tumor cell lines and models. The goal is to test how these tumors respond to various drugs, which may lead to new treatment options and identification of therapy targets. Samples collected include tumor tissue, blood, cerebrospinal fluid, saliva, skull, and dura from patients undergoing neurosurgery. Saliva samples are also collected from parents of pediatric tumor patients. In addition, blood and cerebrospinal fluid samples are taken from patients without tumors undergoing neurosurgery. Post-mortem donations include whole brain, spinal cord, biofluids, and skin biopsies from brain tumor patients. These samples support various analyses such as DNA/RNA sequencing, proteomics, immunoprofiling, and drug screening. Participants provide biological samples during their routine surgical procedures or through autopsy donation. Researchers analyze the genetic, immunohistochemical, cellular, and molecular profiles of the tumor samples over an average of 1 to 3 years. Additional samples from parents and non-tumor patients help with comparisons. This study involves no interventions but focuses on detailed tissue analysis to improve CNS tumor research and future therapies.

Complete this quick 3-step screening to check your eligibility
Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
Duration - Occurs on the day of surgery
Participants undergoing routine neurosurgery provide tissue and biological samples such as tumor tissue, blood, cerebrospinal fluid, saliva, skull, and dura for research purposes if extra tissue is available.
1 surgical collection visit (in-person)
Duration - Occurs post-mortem
Post-mortem biospecimens including whole brain, spinal cord, biofluids, and skin biopsy are collected from participants who donate tissue after passing.
1 collection visit (post-mortem)
Duration - Up to 3 years
Collected samples undergo various analyses such as DNA/RNA extraction, sequencing, methylome analyses, proteomic analysis, immunoprofiling, and primary culturing to support research.
