简要总结
The purpose of this study is to see if Cs-131 brachytherapy is effective in people with recurrent brain cancer who are scheduled to have brain surgery for removal of their tumor(s). The researchers would like to see whether Cs-131 prevents brain tumors from growing back after surgery.The researchers will compare Cs-131 brachytherapy (which occurs during brain surgery) with the usual approach of brain surgery without brachytherapy. The researchers will compare both the effectiveness and safety of the two approaches.

入排标准
入选标准
- •Adult patients ≥ 18 years of age who are capable of giving consent
- •Undergoing elective craniotomy for resection of a previously-irradiated brain metastasis with suspicion for viable disease at the time of consent, and anticipated achievement of gross-total or near-total (\>/=95%) resection
- •Karnofsky Performance Status score (KPS) of ≥70
- •Ability to undergo brain MRI with gadolinium
排除标准
- •Unable to tolerate MRI or CT imaging
- •Pregnancy (patients must have a negative pregnancy test within 30 days of the operation)
- •Women must agree to not breastfeed for at least 12 weeks after the procedure (lactating and discarding in that interval allowable)
- •Diagnosis of leptomeningeal carcinomatosis or \>5 additional active or untreated CNS lesions for a total of \>6 active lesions
- •Prior irradiation (EQD2) in excess of 100 Gy to site of implant, using an α/β of 2
- •Apposition of tumor margin to brainstem or optic apparatus
- •Previous infection within the operative field, current active systemic infection requiring systemic therapy, or immunodeficiency
- •Urgent surgery required prior to availability of brachytherapy
- •Intraoperative Exclusion Criterion:
- •Patients will be excluded if intraoperative pathology is not consistent with \>/=5% viable metastatic disease.
结局指标
主要结局
freedom from local progression
