Survival outcomes in secondary and primary acute lymphoblastic leukemia: a systematic review and meta-analysis.
Synthesis in Scientific reports, 2025. 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
This systematic review and meta-analysis aimed to compare the survival outcomes and cytogenetic profile of primary acute lymphoblastic leukemia (p-ALL) and secondary ALL (s-ALL), including antecedent-malignancy ALL (am-ALL) and therapy-related ALL (tr-ALL). The search was performed in PubMed/MEDLINE, Scopus, Web of Science, Embase, and ProQuest databases from January 1, 1990, to July 31, 2023, using the keywords "acute lymphoblastic leukemia" and "second cancer" to identify cohort studies that compared p-ALL and s-ALL in terms of survival outcomes and cytogenetic profile. The risk of bias in the included studies was assessed using the Joanna Briggs Institute (JBI) for Cohort Studies. A total of 7 studies involving 13,542 participants were analyzed. The results revealed an HR of 2.35 (95%CI:1.38-4.01) for overall survival (OS) and 2.06 (95%CI:1.05-4.06) for relapse-free survival (RFS). Subgroup analysis of tr-ALL patients showed a significantly higher HR of 3.40 (95%CI:2.32-4.99) for OS in this subgroup. Furthermore, the meta-analysis indicated an OR of 3.45 and 5.90 for mixed lineage rearrangement (MLL) and hypodiploidy, respectively. The study highlights the need for a better understanding of the survival rates and cytogenetic profile of secondary ALL, particularly tr-ALL, and the importance of personalized treatment strategies for this subtype.
