Can early surgery stop brain tumors from returning?
NCT ID NCT04810871
First seen Jun 27, 2026 · Last updated Aug 06, 2026 · Updated 2 times
Summary
This study looks at whether removing brain tumors with surgery after chemotherapy or radiation, but before the tumor grows back, is safe and helpful. About 40 adults with remaining tumor after prior treatment will be followed to see how they do compared to those who have surgery later or not at all. The goal is to find the best time for surgery to improve outcomes.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age \>= 18 years * Histological or cytological confirmation of brain tumor and/or suspected brain tumor based on clinical and radiologic findings * Prior chemotherapy and/or radiation treatment directed to the known/suspected tumor * Radiographic evidence of residual or previously unresected tumor * Willingness to undergo surgery and sign informed consent * Patients not currently eligible for an alternate competing interventional clinical trial * Enrollment in the Mayo Clinic Cancer Center Neuro-Oncology Program Registry for the study of Nervous System Tumors (IRB#12-003458) Exclusion Criteria: * Age \< 18 years * Found to be a member of a vulnerable population (e.g. pregnant, lacking capacity to consent) during the course of pre-enrollment or pre-surgical assessment * Prior gross total resection of brain tumor leading to absence of visible latent disease (exemption available for post-operative enrollment) * Any contraindication to surgery, including anyone who in the opinion of the surgeon is at unreasonably elevated risk of wound complications * Patients who have not yet undergone surgery or radiation, but who would be appropriate candidates for an alternate interventional clinical trial (e.g. post-operative fractionated vs single fraction radiation to the surgical cavity for surgical brain metastases)
