Figure 3. . Overall survival of gliosarcoma as a function of surgical resection.

Kaplan–Meier curves showing overall survival of gliosarcoma patients who received biopsy only (solid line) versus any cancer-directed surgical excision of tumor (dashed line) based on analysis of 353 adult gliosarcoma patients identified from the 1988–2004 Surveillance, Epidemiology, and End Results database. Median survival of gliosarcoma patients was significantly improved from 4 months following biopsy only to 7–11 months following any resection.
