Repeat resection for recurrent glioblastoma – does timing matter?
This study analyzed 150 patients with recurrent IDH-wildtype glioblastoma (rGB) to determine the impact of early versus delayed repeat surgical resection on outcomes. While most patients underwent early reoperation (within 6 weeks, mean 54 days), delayed surgery was associated with significantly larger preoperative tumor volumes and a trend towards less favorable extent of resection. However, no significant differences were found in functional outcomes or overall and progression-free survival between early and late surgery groups. The findings suggest that individualized decision-making based on clinical and radiological factors is more critical than timing alone for repeat resection in rGB.

Individualized Decision-Making for rGB
Despite larger tumor volumes in the late surgery group and some differences in the extent of resection and adjuvant treatment patterns, this study found no significant impact of surgical timing alone on functional outcomes or overall patient survival. This highlights the importance of individualizing decisions for repeat resection, considering clinical and radiological factors rather than adhering strictly to a timeline. It also suggests that a carefully selected watch-and-wait strategy or pre-surgical salvage therapy does not necessarily compromise safety or oncological outcomes for appropriate patients.
