Baseline lymphocyte count and osseous tumor volume for prediction of lymphocytopenia. Receiver operating characteristics for the prediction of lymphocytopenia for baseline lymphocyte count (a) and osseous tumor volume (b). Red arrows indicate optimal cut-offs with maximum sensitivity and specificity. Kaplan-Meier curves for event-free survival of lymphocytopenia for baseline lymphocyte count (c) and osseous tumor volume (d) using ROC-derived cut-offs of 1.33 × 10³/mm³ for lymphocyte count and 58cm³ for osseous tumor volume
