Hypothesis
This study evaluates the role of serum concentrations of CA 125, CA 19-9, and SPI in children with leukemia and other malignancies.
Conclusion
The study found that serum concentrations of CA 125, CA 19-9, and SPI are generally within normal limits in children with malignancies, although some may show slight elevations at diagnosis.
Supporting Evidence
- Serum concentrations of CA 125, CA 19-9, and SPI were similar in healthy individuals and patients with acute infection or coeliac disease.
- Some children with malignancies had serum CA 125 and SPI values marginally exceeding the upper limit of reference values.
- Follow-up samples showed that elevated marker levels decreased to below reference values after treatment.
Takeaway
Doctors looked at certain markers in the blood of kids with cancer to see if they could help find or track the disease, but most kids had normal levels.
Methodology
Serum concentrations of CA 125, CA 19-9, SPI, and AFP were measured using radioimmunoassays, and statistical methods included regression and correlation analyses and Student's t test.
Limitations
The study had a small number of patients with certain types of leukemia, which may limit the findings.
Participant Demographics
The study group consisted of 127 children with leukemia or solid tumors, aged 0.2-16 years, including 51 girls and 76 boys.
