Brain metastases in patients under 50 years of age: retrospective analysis.
Several previous publications suggested that younger patients with brain metastases have longer survival than older patients. However, detailed studies of younger patient groups are scarce. Therefore, a multi-institutional analysis of younger patients with brain metastases was performed (defined as adults with age <50 years). Prognostic factors for survival were examined by uni- and multivariate analyses and compared to those obtained in patients with age ≥50 years. Multivariate analysis of 106 patients (median age 44 years, range 23-49 years) revealed three independent prognostic factors for survival: performance status, extracranial metastases and primary tumor control. Survival was significantly better in patients treated after the year 2000 (median 9.4 months) as compared to those treated before the year 2000 (median 5.1 months, p = 0.04). This improvement appeared to be related to an increased use of surgery or radiosurgery (SRS) and decreasing numbers of patients with uncontrolled primary tumor. Irrespective of management approach, survival beyond 5 years was uncommon (actuarial rate 6 %; 17 % in patients treated with upfront surgery or SRS). In conclusion, more intense multidisciplinary approaches aiming at control both in the brain, extracranial metastatic sites, and primary tumor site might have contributed to gradual survival improvements in recent years. Nevertheless, further efforts are necessary to improve long-term survival.
