Insights
Anemia is common in children with solid tumors, particularly neuroblastoma and hepatoblastoma. Bone marrow involvement and chemotherapy can worsen anemia, suggesting a need for targeted anemia therapy in pediatric cancer patients.
Area of Science:
- Pediatric Oncology
- Hematology
Background:
- Solid pediatric tumors present unique challenges in diagnosis and treatment.
- Anemia is a significant concern in children with these cancers.
- Understanding anemia's causes is crucial for effective patient management.
Purpose of the Study:
- To investigate the causes and manifestations of anemia in pediatric patients with solid tumors.
- To evaluate blood parameters before and after chemotherapy in these patients.
- To explore the relationship between anemia, serum ferritin, weight, and bone marrow metastasis.
Main Methods:
- Retrospective cohort study of 235 pediatric solid tumor patients and 200 healthy controls.
- Analysis of blood components (hemoglobin, RBC, WBC, platelets) pre- and post-chemotherapy.
- Assessment of serum ferritin, weight, and bone marrow involvement in specific tumor types.
Main Results:
- Observed various blood parameter derangements in patients with medulloblastoma, neuroblastoma, rhabdomyosarcoma, germ cell tumors, hepatoblastoma, and nephroblastoma.
- Found a correlation between serum ferritin and weight in young neuroblastoma patients (p=0.022).
- Confirmed bone marrow tumor involvement significantly correlates with decreased hemoglobin in neuroblastoma and hepatoblastoma (p=0.001).
Conclusions:
- Anemia can be an early indicator for neuroblastoma, hepatoblastoma, and nephroblastoma.
- Chemotherapy may exacerbate anemia in neuroblastoma and hepatoblastoma patients.
- Anemia management and therapy are essential for pediatric cancer patients.
Background:
Solid pediatric tumors refer to cancers that affect children and adolescents, and they present unique challenges due to their distinct biological characteristics and their vulnerability to young patients. This study aims to shed light on addressing anemia and the causes of anemia in patients with solid pediatric tumors.
Materials And Methods:
This retrospective cohort comprised 200 healthy children as controls and 235 patients with solid tumors. The study was conducted at first Affiliated Hospital of Zhengzhou University between January 2020 and June 2023. We evaluated different parameters of blood components in controls and patients with solid tumors such as medulloblastoma, neuroblastoma, rhabdomyosarcoma, germ cell tumors, hepatoblastoma and nephroblastoma before and patients with only these tumors 3 weeks after the first cycle of chemotherapy. Further, we evaluated the relationship between serum ferritin and the weight of patients and assessed the relationship between anemia and metastasis to the bone marrow in patients with neuroblastoma and hepatoblastoma.
Results:
We observed various combinations of derangements in blood parameters such as hemoglobin, red blood cells, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, hematocrit, red cell distribution width, white blood cells, and platelet in medulloblastoma, neuroblastoma, rhabdomyosarcoma, germ cell tumors, hepatoblastoma and nephroblastoma before and 3 weeks after first cycle of chemotherapy. We found a significant correlation between serum ferritin levels and weight in neuroblastoma patients who are ≤ 2 years (p = 0.022). Involvement of tumor cells in bone marrow correlates with decreased Hb level in both neuroblastoma (CI = 93.21-106.68, p = 0.001) and hepatoblastoma (CI = 113.36-121.00, p = 0.001).
Conclusion:
Anemia may manifest as an early symptom in neuroblastoma, hepatoblastoma, and nephroblastoma. Also, anemia may be worse in patients with neuroblastoma and hepatoblastoma after chemotherapy and might warrant anemia therapy.
