In addition, although the difference was not statistically significant, patients with <3 brain metastases showed a favorable trend toward longer OS compared with those with ≥3 lesions (33.9% vs. 29.7%, p = 0.066).
In addition, although the difference was not statistically significant, patients with <3 brain metastases showed a favorable trend toward longer OS compared with those with ≥3 lesions (33.9% vs. 29.7%, p = 0.066).
Systemic treatment was also shown to significantly improve OS in univariate analysis ( p = 0.003), but it did not reach statistical significance in multivariate analysis ( p = 0.132).
The association was statistically significant in the BRAF + MEK inhibitor (HR = 0.618, 95% CI: 0.429–0.891) and chemotherapeutic regimens (HR = 0.600, 95% CI: 0.405–0.889) subgroups, and marginally significant in the immunotherapy subgroup (HR = 0.672, 95% CI: 0.451–1.002).
