Four-year Survival (and Counting) after Stereotactic Radiosurgery to Nearly 100 Brain Metastases: A Case Report.

Brain metastases are a relatively common consequence of Stage IV melanoma. Historically, patients with brain metastases fare poorly, with median survival of only weeks to months. Patients with multiple metastases in the brain have often been overlooked in the literature, with the focus being placed more on patients with only a small number of metastases. The authors present a case of a 42-year-old man with a total of 98 brain metastases treated over several Gamma Knife sessions. He is nearly five years out from his initial treatment. This case highlights the fact that there is a large amount of variability in survival after diagnosis with brain metastases. Selection for treatment should be based on the clinical picture and clinicians should take care to avoid selection bias in this population.
