Background: The impact of surgical resection on the survival and functional outcomes of patients with multiple brain metastases remains a critical question in neuro-oncology. Methods: This retrospective study involved 160 patients who underwent surgical resection of brain metastases from 2017 to 2020. Patients were classified by the number of metastases—single, oligometastatic, or multiple—and whether complete removal of the main symptomatic lesion was achieved. Outcomes such as survival rates, complications, and functional status were assessed. Results: Among the patients, 48.1% had a single metastasis, 21.9% were oligometastatic, and 30% had multiple metastases. Survival did not differ by number of metastases when the main lesion was completely resected and remaining lesions were radiated (p = 0.6172). Complete resection increased mean survival to 15.74 months compared with 4.5 months without it. Additionally, patients who underwent complete resection experienced fewer seizures (16.2% vs. 32.6%, p = 0.019), implying a lower seizure risk. Functional independence was maintained post-surgery. Conclusions: While multiple brain metastases are generally associated with poor outcomes, a trend toward longer survival was observed after complete resection of the index metastasis, though this was not statistically significant. Radiation of residual lesions remains important to support prognosis. Reducing the tumor volume is key to lowering seizure risk. This study supports the role of aggressive surgical interventions, paired with radiation, to potentially enhance outcomes in patients with multiple brain metastases.
