[Therapy of brain metastasis based on the RPA classification]

RPA classification of patients suffering from brain metastases is not widely used in Hungary. The authors reviewed the RPA disposition-based therapeutic recommendations in the literature. Retrospective analysis of their 123 brain metastatic cases showed 3.8 months median, 34.1% 1-year and 7.9% 2-year overall survival. Patient number and median survival in subgroups: RPA 1: 42/14 months, RPA 2: 38/6,2 months, RPA 3a: 6/3.1 months, 3b: 13/2 months, 3c: 10/0.7 months. Median survival of patients with brain metastases from cancer of unknown primary (CUP) was 3 months. In RPA class 1 and 2, 10% undertreatment has been found for solid brain metastases, and all of the 3c patients were over-treated according to literature recommendations. The authors strongly recommend the use of RPA classification in the management of brain metastases and in contemplation of the capacity of radiotherapy/neurosurgery and oncology.
