Discussion

Analysis shows elevated sphingosine-1-phosphate levels link to brain metastasis in EGFR-mutant LUAD, suggesting its role as a potential biomarker.

Elevated serum S1P levels are significantly associated with brain metastasis in EGFR-mutant lung adenocarcinoma patients.
In EGFR-mutant patients, the odds of brain metastasis risk increased by 8.2 times with high S1P levels, a significant finding with p = 0.003.
Kaplan-Meier analysis indicated that high serum S1P levels correlated with earlier onset of brain metastasis in EGFR-mutant patients.
The presence of bone metastasis did not significantly influence the relationship between S1P levels and brain metastasis.

Xu et al. (2025) studied this question.
