Surgical resection of brain metastases is done in 15%\u201320% of these patients. While gross total resection (GTR) is believed to extend overall survival (OS), concerns exist regarding increased morbidity. This study examines the impact of surgical resection, particularly GTR, on self-reported symptoms, focusing on quality of life (QoL) and motor dysfunction.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>We conducted a prospective cohort study involving adult patients undergoing surgical resection for brain metastases from solid tumors in a defined region of Norway between 2017 and 2021. Clinical data were collected at inclusion prior to surgery and every 3 months the first year. Patients completed monthly questionnaires assessing QoL and motor dysfunction. QoL was measured using the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C15-PAL, while motor dysfunction was evaluated using the EORTC QLQ-BN20.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>A total of 155 patients were included and median OS was 13 months. GTR was achieved in 69 (44%) patients and was associated with longer median OS compared to subtotal resection (17.7 vs. 10.9 months, P\u2005=\u2005.04). Mean QoL remained stable throughout the follow-up period. Improved motor dysfunction 1 month after surgery was reported by 23% of the patients, while 25% reported worse motor dysfunction. Factors associated with a high motor dysfunction score at 1 month were age &amp;gt;70 years, higher baseline motor dysfunction, and multiple brain metastases. Neither GTR nor location of metastases in motor-associated areas were associated with worsened motor dysfunction.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Self-reported QoL is maintained after surgery for brain metastases.
