Abstract

Background The prevalence of iron deficiency (ID) and iron deficiency anemia (IDA) in children with cancer is not well studied. The detection of ID and IDA using sensitive laboratory tools may facilitate early diagnosis and treatment in this cohort. In this regard, reticulocyte hemoglobin (Ret-He) content serves as a cost-effective measurement that remains unaffected by inflammation, unlike the ferritin test. Aim The objective of this study is to analyze the role of Ret-He as a diagnostic tool to identify functional and absolute ID and IDA in children with cancer. Methods We conducted a cross-sectional study in children aged 0 to 18 years. Blood samples were collected to compare Ret-He values with iron status, reflected by hemoglobin (Hb), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), serum iron (SI), total iron binding capacity (TIBC), and ferritin and transferrin saturation. The overall discriminative power of Ret-He in detecting ID and IDA was assessed using receiver operating characteristic analysis. Results Of the 135 children included in the study, 58 (43.0%) had anemia. Among them, 20 (14.8%) had IDA (8 [5.9%] absolute and 12 [8.9%] functional), while 25 (18.5%) had ID (16 [11.9%] absolute and 9 [6.7%] functional). The Ret-He value was significantly related to iron status (p ≤ 0.002). Ret-He was also shown to have a significant correlation with the abovementioned hematological parameters (p = 0.000), except TIBC. Multivariate analysis revealed a significant relationship between Hb (p = 0.051), MCH (p = 0.000), and MCHC (p = 0.001) and Ret-He. Ret-He values of 33.7, 32.7, 32.4 and 28.6 pg were established as optimal cut-off values to identify functional ID, absolute ID, functional IDA, and absolute IDA, respectively. Conclusion Ret-He is a reliable diagnostic tool for absolute and functional IDA in children with cancer.
