- Surgical bed recurrence-free survival (SB-RFS) [ Time Frame: From the time of randomization up to 2 years post radiation ]Surgical bed control is defined as the absence of new nodular contrast enhancement in the surgical bed. In other words, a surgical bed recurrence-free survival (SB-RFS) event is defined as radiographic evidence of a new contrast-enhancing lesion (specifically any new progressive enhancing nodularity) at the site of the surgical resection. Will use a stratified log-rank test that compares and will report the median SB-RFS times between the single fraction stereotactic radiosurgery (SSRS) and fractionated stereotactic radiosurgery (FSRS) arms while adjusting for the stratification factors.
- Change in Functional Assessment of Cancer Therapy-Brain (FACT-BR) Emotional sub-scale score [ Time Frame: At 9 months ]The average change from baseline to 9 months in the Functional Assessment of Cancer Therapy-Brain (FACT-BR) Emotional sub-scale will be compared between randomization arms.
- Functional Assessment of Cancer Therapy-Brain (FACT-BR) total score [ Time Frame: At 9 months ]The average change from baseline to 9 months in the Functional Assessment of Cancer Therapy-Brain (FACT-BR) total score will be compared between randomization arms.

- Linear Analog Self-Assessment (LASA) overall quality of life for long-term survivors [ Time Frame: At 12 months ]Long-term survivors defined as patients who are alive more than 12 months from time of randomization. The average change from baseline to 9 months in the Linear Analog Self-Assessment (LASA) overall total score for the long-term survivors will be compared between randomization arms.
- Karnofsky Performance Status (KPS) [ Time Frame: Up to 24 months ]The duration of Karnofsky Performance Status (KPS) functional independence will be the time to when the KPS scores per patient decrease below their baseline level and will be compared between treatment arms by the logrank test. Median durations of KPS functional independence will be reported and compared between randomization arms.
- Barthel Activities of Daily Living (ADL) Index [ Time Frame: Up to 24 months ]The duration of Barthel Activities of Daily Living (ADL) functional independence will be the time to when the ADL scores per patient decrease below their baseline level and will be compared between treatment arms by the logrank test. Median durations of ADL functional independence will be reported and compared between randomization arms.
- Karnofsky Performance Status (KPS) for long-term survivors [ Time Frame: Up to 24 months ]Long-term survivors defined as patients who are alive more than 12 months from time of randomization. The duration of Karnofsky Performance Status (KPS) functional independence will be the time to when the KPS scores per patient decrease below their baseline level and will be compared between treatment arms by the logrank test. Median durations of KPS functional independence for long-term survivors will be reported and compared between randomization arms.
- Barthel Activities of Daily Living (ADL) Index for long-term survivors [ Time Frame: Up to 24 months ]Long-term survivors defined as patients who are alive more than 12 months from time of randomization. The duration of Barthel Activities of Daily Living (ADL) functional independence will be the time to when the ADL scores per patient decrease below their baseline level and will be compared between treatment arms by the logrank test. Median durations of ADL functional independence for long-term survivors will be reported and compared between randomization arms.
- Overall survival [ Time Frame: Up to 5 years ]Overall survival time will be compared between the treatment arms using a stratified log-rank test. If the proportional hazards assumption is violated, a restricted means analysis will be used to compare overall survival between the two treatment arms. Median survival times per treatment arms will be reported.
- Incidence of adverse events [ Time Frame: Up to 24 months ]The Common Terminology Criteria for Adverse Events version 5.0 will be used. The proportion of patients experiencing any adverse event will be compared between the two treatment arms using a chi-square (or Fisher's exact test, if more appropriate).
- Proportion of patients with radiation necrosis [ Time Frame: At 24 months ]The proportion of patients with radiation necrosis within 24 months from of starting treatment will be compared between the treatment arms with a chi-square test (or Fisher's exact test if more appropriate).
- Time until whole-brain radiotherapy (WBRT) due to any reason (e.g. surgical bed recurrence, recurrence/progression at another central nervous system [CNS] site) [ Time Frame: Up to 24 months ]Time until whole-brain radiotherapy (WBRT) will be compared between the treatment arms using a stratified log-rank test. Median time until WBRT per treatment arms will be reported.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
PRE-REGISTRATION:
- Pathology from the resected brain metastasis must be consistent with a non-central nervous system primary site. Patients with or without active disease outside the nervous system are eligible (including patients with unknown primaries), as long as the pathology from the brain is consistent with a non-central nervous system primary site.
-
Three or fewer (i.e. 0 to 3) unresected brain metastases (as defined on the post operative magnetic resonance imaging [MRI]) at the time of screening.
o Note: Dural based metastases (e.g. commonly seen in breast cancer) are eligible.
-
Unresected lesions must measure < 4.0 cm in maximal extent on the contrasted post-operative treatment MRI brain scan. The unresected lesions will be treated with SRS as outlined in the treatment section of the concept.
o Note: The metastases size restriction does not apply to the resected brain metastasis.
-
One brain metastasis must be completely (gross total resection) resected =< 30 days prior to pre-registration.
o NOTE: May not have had resection of more than one brain metastasis.
- The resected brain metastasis must measure 2 cm or larger on the pre-operative MRI.
- Resection cavity must measure < 5.0 cm in maximal extent and the resection must be complete (gross total resection) on the post-operative MRI obtained =< 30 days prior to pre-registration.
- Karnofsky performance status of >= 60.
-
For women of childbearing potential only, a negative urine or serum pregnancy test done =< 7 days prior to pre-registration is required.
- Men and women of childbearing potential must be willing to employ adequate contraception throughout the study and for men for up to 3 months after completing treatment.
- A female of childbearing potential is a sexually mature female who: 1) has not undergone a hysterectomy or bilateral oophorectomy; or 2) has not been naturally postmenopausal for at least 12 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months).
- Ability to complete an MRI of the head with contrast.
- The brain metastasis must be located > 5 mm of the optic chiasm; the brain metastasis must be located outside the brainstem (i.e. not inside the brainstem).
- Must not have any prior whole brain radiation therapy.
-
Past radiosurgery to other lesions is allowed.
o NOTE: The surgically resected lesion cannot be the same location treated in the past with radiosurgery (i.e. repeat radiosurgery to the same location/lesion is not allowed on this protocol).
- May not have primary germ cell tumor, small cell carcinoma, or lymphoma.
-
No evidence of leptomeningeal metastasis (LMD).
o NOTE: For the purposes of exclusion, LMD is a clinical diagnosis, defined as positive cerebrospinal fluid (CSF) cytology and/or equivocal radiologic or clinical evidence of leptomeningeal involvement. Patients with leptomeningeal symptoms in the setting of leptomeningeal enhancement by imaging (MRI) would be considered to have LMD even in the absence of positive CSF cytology, unless a parenchymal lesion can adequately explain the neurologic symptoms and/or signs. In contrast, an asymptomatic or minimally symptomatic patient with mild or nonspecific leptomeningeal enhancement (MRI) would not be considered to have LMD. In that patient, CSF sampling is not required to formally exclude LMD, but can be performed at the investigator's discretion based on level of clinical suspicion.
- Must be fluent in English, Spanish, or French.
REGISTRATION:
• Completion of all baseline electronic patient-reported outcome (ePRO) quality of life measures (or booklet quality of life measures) and Montreal Cognitive Assessment (MoCA).
