Optimizing Diagnostic Tools & Outcomes Evaluation for t (9;22)-Positive Leukemias in Pediatric Low Middle-Income Country (LMIC) Patients.

Accurate and timely diagnosis of t(9;22)-positive leukemias is vital to improving survival in pediatric patients. In low-resource settings, where healthcare disparities are exacerbated by limited resources, cost-effective and efficient diagnostic methods are essential for bridging these gaps and ensuring better outcomes. Among the diagnostic tools evaluated among 23 patients sample, RT-PCR demonstrated superior sensitivity (100%) and the shortest turnaround time (7 days), significantly outperforming FISH and karyotyping in both accuracy and timeliness. This capability of RT-PCR to provide reliable and rapid results enables earlier treatment initiation, which is critical in managing these aggressive leukemias. Simplified statistical reporting underscores RT-PCR's unmatched sensitivity, while FISH and karyotyping, though useful, showed moderate performance with longer delays. By adopting RT-PCR as the primary diagnostic tool in LMICs, healthcare systems can make faster and more accurate treatment decisions, reduce overall treatment costs by avoiding diagnostic delays, and ultimately improve survival rates in pediatric leukemia patients.
