The Role of Neoadjuvant Therapy to Improve the Extent of Resection in "Unresectable" Gliomas.
Surgical resection plays a pivotal role in the management of glial tumors and a greater extent of resection (EOR) should be the goal in most surgeries to improve overall survival. Many factors may limit the EOR. A potential role for preoperative chemotherapy to decrease the volume and/or infiltration of gliomas, thereby facilitating a safe radical resection, has been recently suggested. This review aims to provide an overview of the current state of neoadjuvant therapy in the field of glioma surgery. ⋯ Neoadjuvant chemotherapy has played a role in overcoming obstacles that limit the EOR in patients with complex gliomas, especially low-grade gliomas.
