With therapies for systemic malignancy improving, life expectancy for cancer patients is becoming increasingly dependent on control of brain metastatic disease. Despite improvements in surgical and radiotherapy modalities for control of brain metastasis, the prognosis for patients with brain metastases is poor. The development of controlled release polymers has lead to novel new therapies for malignant brain tumors consisting of direct surgical delivery of chemotherapy agents to the tumor bed and sustained chemotherapy release over a prolonged period of time. Although there is a large body of literature in support of BCNU polymer wafer for primary brain malignancy and experimental brain metastases, clinical studies evaluating the BCNU polymer wafer for brain metastatic disease are relatively sparse. In this review, we discuss the role of the BCNU polymer wafer for brain metastasis focusing specifically on rationale for use of locally delivered sustained release polymers, history of the BCNU polymer wafer, and emerging studies examining the role of the BCNU polymer wafer for metastatic brain tumors.
