Mutations Encountered in Acute Lymphoblastic Leukemia: A Retrospective Study in a Teaching Hospital in Jeddah, Saudi Arabia.

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
Background Acute lymphoblastic leukemia (ALL) is an invasive cancer that results from the malignant conversion and rapid replication of white blood cells and hematopoietic stem cells that supply multiple lymphocytes. Harmful gene mutations occur in more than two-thirds of patients with ALL; however, these mutations have not been extensively identified in Saudi Arabia. Aim The aim of this study was to identify the types of mutations in patients with ALL at King Abdulaziz University Hospital (KAUH) in Jeddah. In addition, we identified the most common mutations. Methods A retrospective study was performed on patients who were diagnosed with ALL from January 2009 to January 2019 at the Department of Hematology at KAUH. Our target population comprised patients diagnosed with ALL, including all age groups and both sexes. Patients were excluded if they had Down syndrome or central nervous system involvement, Li-Fraumeni syndrome, or neurofibromatosis. Results Of the 130 patients with ALL, 101 (77.77%) were children. The number of men (n=81) was substantially more than that of women (n=49). The data showed that 13.1% of our patients had mutations, and they occurred more frequently in patients with B-cell lymphoblastic ALL (B-ALL) than in those with T-cell lymphoblastic ALL (T-ALL). Several mutations, including BCR-ABL and ETV6/RUNX1, were more common in B-ALL, whereas the MLL-F0X04mutation was more commonly observed in T-ALL. There was a significant difference between the types of ALL and the genes involved (p=0.039). One female patient had translocation t(X;11)(q26;q23) (MLL-F0X04), which is a rare mutation. Conclusion In summary, 13.1% of our study population had mutations. The BCR-ABL fusion gene was the most frequent mutation in patients at KAUH, and it occurred at a higher rate in B-ALL. Moreover, we detected other mutations, such as ETV6/RUNX1 and MLL-F0X04. The gene mutations were significantly different between B-ALL and T-ALL.
