Eligible studies evaluated TLS presence, density, maturity, or spatial distribution in histologically confirmed HNSCC.

Absence of TLSs was associated with worse overall survival (HR: 2.20, 95% CI: 1.74\u20132.78,\n                      <jats:italic>I<\/jats:italic>\n                      <jats:sup>2<\/jats:sup>\n                      \u2009=\u200926%) and poorer DFS (HR: 2.21, 95% CI: 1.49\u20133.28,\n                      <jats:italic>I<\/jats:italic>\n                      <jats:sup>2<\/jats:sup>\n                      \u2009=\u20090%). This adverse prognostic effect persisted in the OSCC subgroup (HR: 1.97, 95% CI: 1.42\u20132.73,\n                      <jats:italic>I<\/jats:italic>\n                      <jats:sup>2<\/jats:sup>\n                      \u2009=\u200928%). Beyond quantitative presence, TLS maturation and spatial distribution influenced prognosis, with mature intratumoral TLSs associated with more favorable outcomes. Moreover, emerging evidence suggests that TLSs may also predict response to immunotherapy, particularly immune checkpoint blockade.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>TLSs are strong prognostic biomarkers in HNSCC. Their presence, maturity, and spatial context significantly influence survival, supporting their role in prognostic stratification and future therapeutic strategies.
