CCL20 and hematopoietic and lymphoid cell neoplasm: These results not only validate previous findings in both pediatric and adult patients with hematological cancer, suggesting that citrulline and CCL20 could be valuable in identifying individuals at higher risk of developing BSI during chemotherapy [16, 30–33], but more importantly, they also propose that markers of mucositis can serve as predictive indicators for BSI when patients are admitted with fever.
