CD27 and Tumor Lysis Syndrome: Cox proportional regression showed that stage (p = 0.0006), CD70 score (p = 0.0064), stromal- (p = 0.003) and intratumoral (p = 0.0024) CD20 density, and TLS presence (p = 0.02) is prognostic, gender (p = 0.098) and adjuvant chemotherapy (p = 0.086) is borderline prognostic, whereas age (p = 0.721) and CD27 score (p = 0.607) is not prognostic according to univariate analyses (Table 2).
