Molecular Detection of Fusion Oncogenes in Zambian Patients with Acute Lymphoblastic Leukemia.
Article in International journal of applied & basic medical research. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionChromosomal aberrations play a significant role in the pathogenesis of acute lymphoblastic leukemia (ALL) with prognostic and therapeutic implications. Despite the availability of molecular tools, low-resource settings struggle to diagnose the disease due to limited diagnostic capacity. The objective of this study was to detect common chromosomal aberrations in patients with ALL attending the University Teaching Hospital (UTH) in Lusaka, Zambia. MATERIALS AND
methodsIn this prospective study, 19 blood samples from patients with ALL were screened for the presence of BCR-ABL, E2A-PBX1, MLL-AF4, and ETV6-RUNX1 fusion oncogenes using reverse transcriptase-polymerase chain reaction assay. Blood counts and clinical characteristics of patients were also assessed.
resultsThe age of patients ranged from 1½ to 72 years and comprised 57.9% of males and 42.1% of females. The majority of these patients were children (68%), and adults only comprised 32%. Only BCR-ABL and E2A-PBX1 oncogenes were detected in 3/19 of cases. The BCR-ABL gene was detected in a 4-year-old female child and a 15-year-old child. Both cases were associated with hepatomegaly and anemia coupled with low hemoglobin, white blood cell, and platelet counts. E2A-PBX1 was detected in a 12-year-old child with lymphadenopathy and splenomegaly, coupled with low hemoglobin, white blood cell, and platelet counts. All the three patients who harbored these fusion oncogenes died.
conclusionThis is the first study from Zambia to investigate the presence of fusion oncogenes in leukemia patients, which were found only among the older children population. Based on these findings, we recommend that molecular diagnosis be made a priority for the younger leukemia patient population at UTH.
