Despite substantially improved survival with rituximab-based treatment regimens, there is an unmet medical need for better treatments of B-cell lymphoma, particularly for patients with relapsed or refractory disease. Retreatment with rituximab exerts a limited effect in these patients, and platinum-based salvage treatment followed by autologous stem cell transplantation remains the only curative option. Recent strategies have focused on targeting novel B-cell surface markers, inhibiting B-cell receptor signaling, and enhancing the cytotoxicity of effector cells. The current article will review the recent progress in immunochemotherapy targeting other than CD20 for B-cell lymphomas.
