Outcome Measures
Primary Outcomes (1)
Intra-cranial progression-free survival (IPFS)
Defined as the time from date of radiation until the date of first documented intracalcarine recurrence or progression, or date of death from any cause, whichever came first.
From the date of radiation until the date of first documented intracalcarine recurrence or progression, or date of death from any cause, whichever came first, assessed up to 12 months.
Secondary Outcomes (5)
Local control rate (LCR)
Tumor assessment using RECIST will be performed at baseline then every 3 months from first treatment until objective progression or death from any cause, assessed up to 12 months.
Overall survival (OS)
From the date of radiation until the date of any documented death due to any cause,, assessed up to 12 months.
Objective Response Rate (ORR)
Tumor assessment using RECIST will be performed at baseline then every 3 months from first treatment until objective progression or death from any cause, assessed up to 12 months.
Disease control rate (DCR)
Tumor assessment using RECIST will be performed at baseline then every 3 months from first treatment until objective progression or death from any cause, assessed up to 12 months.
Adverse Event
AEs and SAEs must be collected from the start of treatment to 28 days after discontinuation of radiation, up to 12 months.
Study Arms (1)
