Overview
This is a pilot imaging study in participants treated with stereotactic radiosurgery (SRS) to treat brain metastasis. The purpose of this study is to see whether 18F-Fluciclovine positron emission tomography (PET) can be used as a biomarker to measure response or progression of brain metastasis after SRS.
Eligibility
Inclusion Criteria:
- Diagnosis of cancer with radiographic finding of brain metastasis
- Any number of brain metastasis, with all lesions ≤ 2 cm in maximum dimension
- Planned treatment with SRS as per the treating physician team
- Eastern Cooperative Oncology Group (ECOG) performance status 0-2
- Individuals of reproductive potential need to employ two highly effective and acceptable forms of contraception for at least 4 weeks prior to screening and agree to use such a method during study participation up to an additional 1 week following the last 18F-fluciclovine PET
Exclusion Criteria:
- Prior anaphylactic reaction to 18F-fluciclovine
- Radiographic evidence of leptomeningeal disease
- Prior whole-brain radiation therapy
- Inability to undergo MRI (e.g., due to safety reasons, such as presence of a pacemaker)
- Pregnant or positive serum pregnancy test within 14 days of registration
- Individuals expecting to be breastfeeding at the time of 18F-fluciclovine and unwilling to stop breast-feeding for 24 hours. Temporary cessation of breastfeeding for 24 hours after the time of imaging is allowed.
- Major medical illness or psychiatric/cognitive impairments, which in the
investigator's opinion, will prevent completion of protocol and/or preclude informed
consent*
- A legally authorized representative (LAR) may consent on a potential participant's behalf in the case of cognitive impairment, if in the investigator's opinion, that impairment would not prevent completion of the protocol.
