Stereotactic Radiation Therapy (SRT) for Brain Metastases of Multiple Primary Tumors: A Single Institution Retrospective Analysis

Purpose: To evaluate the efficiency and side effects of stereotactic radiation therapy (SRT) with or without other treatments for brain metastases (BM) from various primary tumors.Methods: This was a retrospective analysis of 161 patients with brain metastases treated with SRT. Clinical data, EGFR mutation status and survival data were collected. Follow-up data was analyzed until December 2018. Kaplan-Meier and Cox proportional hazards regression analyses were used for the survival analysis.Results: The median overall survival (OS) was 19 months. No difference was observed in OS between SRT group and SRT + whole brain radiation therapy (WBRT) groups (p = 0.717). Statistically significant factors of better OS after univariable analysis were no extracranial metastases (p = 0.016), BED10-SRT≥50Gy (p = 0.049), oligometastases (1–3 brain metastases) (p

Conclusion: In patients presenting with oligometastatic lung cancer limited to the brain, treatment with both lung SBRT and brain SRS achieves good LC of all sites with encouraging OS. PMID: 31956701 [PubMed]

Abstract BACKGROUND AND PURPOSE: To analyze outcomes of non-small cell lung cancer (NSCLC) patients with brain metastases harboring EGFR or ALK mutations and examine for differences between tyrosine kinase inhibitors (TKIs) alone, radiotherapy (RT) alone (either whole brain radiation therapy (WBRT) or stereotactic radiosurgery (SRS)), or combined TKIs and RT. MATERIALS AND METHODS: Thirty studies were identified. PATIENTS: with brain metastases from NSCLC. INTERVENTION: initial TKIs alone with optional salvage RT, RT alone, or TKIs and RT. CONTROL: wild-type NSCLC and TKIs alone for mutational ...

In conclusion, this is the first study to demonstrate the negative survival impact from the omission of WBRT in patients with EGFR-mutant NSCLC.

We assessed four anaplastic lymphoma kinase (ALK) ‐positive non‐small cell lung cancer (NSCLC) patients who were treated with ALK‐tyrosine kinase inhibitors (TKIs). They developed brain radiation necrosis and brain oedema after stereotactic irradiation. Here, we report the efficacy and safety of bevacizumab given in combination with ALK‐TKI s for brain radiation necrosis in ALK‐positive NSCLC. Central nervous system (CNS) metastases from anaplastic lymphoma kinase (ALK) ‐positive lung cancer often results in failure of ALK‐tyrosine kinase inhibitor (TKI) therapy. Patients with uncontrolled CNS metastases rece...
