Abstract: | Overall survival in diffuse large B-cell lymphoma (DLBCL) has significantly improved in the last decade, especially after the incorporation of rituximab. Involvement of the central nervous system (CNS) at presentation or at recurrence is an uncommon event, but carries a dismal prognosis with median survival of less than 6 months. Although prophylactic CNS directed therapy is a widely used approach to prevent this complication, randomized clinical trials have been very limited. CNS prophylaxis has inherent toxicities; therefore, identifying the population of patients who would receive most benefit is of utmost importance. From an extensive review of current literature, we report the incidence of CNS relapse in DLBCL and describe the role of CNS prophylaxis in the post-rituximab compared to the pre-rituximab era. We also review the current modalities of CNS prophylaxis and attempt to identify the high-risk patients who would benefit. Lastly, we present a treatment algorithm that defines the role of CNS prophylaxis in the management of patients with DLBCL. |
