Baseline LDH, analyzed as a continuous variable, retained a highly significant effect (adjusted HR 1.006 per U/L, 95% CI 1.003–1.009, p < 0.001).
Baseline LDH, analyzed as a continuous variable, retained a highly significant effect (adjusted HR 1.006 per U/L, 95% CI 1.003–1.009, p < 0.001).
Notably, maintenance immunotherapy showed a strong trend: patients who did not continue immunotherapy had a higher risk of death (HR 1.64, 95% CI 0.96-2.81) with p = 0.07 in univariate analysis.
In contrast, the association between maintenance immunotherapy and overall survival was attenuated and did not reach statistical significance in the imputed analysis (HR 0.543, 95% CI 0.273–1.079, p=0.079).
Our cohort showed a trend toward worse survival with higher SII, consistent with prior studies ( 12 ).
