Summary
Accurate bone marrow assessment is crucial for neuroblastoma staging and treatment. Combining bone marrow aspirate smears and trephine biopsies improves detection of cancer infiltration, aiding patient management.
Area of Science:
- Pediatric Oncology
- Hematopathology
Background:
- Bone marrow involvement in neuroblastoma signifies advanced disease.
- Accurate assessment is vital for treatment decisions, including autologous bone marrow rescue.
Purpose of the Study:
- To evaluate bone marrow infiltration in neuroblastoma patients.
- To correlate infiltration status with hematological parameters.
- To compare diagnostic yield of bone marrow aspirate smears and trephine biopsies.
Main Methods:
- Analysis of 44 neuroblastoma cases.
- Examination of bone marrow aspirate smears and trephine biopsy sections.
- Correlation with hematological parameters like leucopenia and bicytopenia.
Main Results:
- 54.5% of cases showed bone marrow infiltration.
- Leucopenia and bicytopenia were significantly associated with infiltration (p < 0.05).
- Combined aspirate smears and biopsies detected all positive cases, outperforming individual methods.
Conclusions:
- Bone marrow infiltration is common in neuroblastoma.
- Hematological abnormalities correlate with marrow involvement.
- A combined approach of bone marrow aspirate and biopsy offers the highest sensitivity for detecting neuroblastoma infiltration.
