<p>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.&#xa0;</p>

摘要

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.
