Summary
Brief summary (as posted)
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.

- 18F-Fluciclovine PET Imaging
- description
- Participants will undergo a 18F-fluciclovine PET scan at the time of their SRS planning magnetic resonance imaging (MRI). Then participants will undergo single-fraction SRS as standard of care (SOC). A second 18F-fluciclovine PET scan will be completed 8 weeks (± 2 weeks) after SRS.

Primary outcomes (3)
- measure
- Change in Standardized Uptake Value (SUV)-peak
- timeFrame
- 8 weeks
- description
- Each 18F-fluciclovine PET will undergo quantitative image analysis by the study nuclear medicine physician. The lesion on each PET will be correlated with the lesion on the corresponding contrast-enhanced MRI and will be delineated. The SUVpeak will be calculated for the pre-SRS and post-SRS imaging studies, as well as the percent change from pre to post will be calculated. Assuming SRS reduces the tumor size, a negative percent change (decrease) is expected.

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.
