Two independent reviewers assessed studies for eligibility and extracted data. Study quality was evaluated using the ROBINS-I and ROBINS-II tools. The primary outcome was overall survival (OS); secondary outcomes included progression-free survival (PFS), toxicity, and prognostic factors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The meta-analysis demonstrated a significant improvement in OS with combined BEV and re-irradiation compared to BEV alone (hazard ratio (HR) 0.69, 95% confidence interval (CI: 0.56\u20130.85);\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u2009=\u20090.0005), corresponding to a 31% reduction in the risk of death.

No significant increase in grade 3 toxicities was observed with the combination therapy. Subgroup analyses indicated that younger age and female gender were statistically associated with better OS, though the effect of age was modest and male gender was linked to poorer survival. Karnofsky performance status significantly influenced survival.
