Asymptomatic brain metastases, EGFR mutation, Whole brain radiotherapy, Stereotactic radiosurgery, ALK rearrangement
Brief summary
Tyrosine Kinase Inhibitors (TKIs) especially higher generation TKI have higher CNS penetration rates and have shown favorable response rates in brain metastases. Brain radiotherapy/surgery is the standard treatment in brain metastases especially symptomatic metastases, however, the role of local treatment especially in driver mutation-positive non-small cell lung cancer with asymptomatic brain metastases is being questioned given their potential side effects. No randomized trial has shown the superiority of early vs delayed cranial RT in asymptomatic BM of driver mutated NSCLC.
Interventions

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Intracranial progression free survival at 24 months | 2 year | Intracranial progression free survival will be defined as the time from the date of randomization until the date of intracranial progression is documented. Death without intracranial progression will be considered as a competing event. Intracranial response will be graded as per the Response Assessment in Neuro-Oncology (RANO) guidelines for brain metastases |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Overall Survival | Upto 5-year | Overall survival will be defined as the time from randomization until the date of death from any cause in the presence or absence of recurrence. |
| Progression free survival | upto 2 year | Progression free survival will be defined from the date of randomization to the date of progression or the date of death whichever is earlier. |
| Neurocognition toxicity | Upto 12 months | Neuro-cognition assessment will be done using HVLT-R (Total Recall) at baseline and at 3, 6 and 12 months for assessable patients |
| Toxicity using CTC v5.1 | Upto 2 years | Toxicity assessment will be defined as per the common terminology criteria version 5.0 at baseline and at subsequent follow up till 2 years |
| Local Control | Upto 2 years | — |
