Although there is still no consensus on how to integrate these elements to best guide treatment choice, multiparametric models, commonly called fitness scores, have been developed to evaluate each patient's ability to tolerate therapies. These models consider various risk factors, including disease biology, comorbidities, physical and cognitive function. To date, several scoring systems can be used to categorize patients on their fitness for intensive or non-intensive therapies. However, existing tools mainly focus on identifying patients suitable for conventional intensive chemotherapy and fail to address the complexities of less-fit patients who might benefit from innovative intensive, less-intensive, and even maintenance strategies. As treatment landscapes are in constant evolution, identifying intermediate level of fitness through recalibration of existing scores or development of new ones should be prioritized. Considering all the above, this review aims to report on the state of the art of fitness assessment in AML and discuss possible future directions on this topic.</div></div>","PeriodicalId":50603,"journal":{"name":"Current Opinion in Pharmacology","volume":"83 ","pages":"Article 102527"},"PeriodicalIF":4.0,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143947657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite advancements in chemotherapy, allogeneic hematopoietic stem cell transplantation, and post-remission maintenance therapies, the long-term survival remains unsatisfactory with high rates of relapse and refractory. These therapeutic challenges are mediated by multiple factors, including the complexity of the cellular hierarchies in AML, the interaction of leukemic stem cells (LSCs) with the bone marrow niche, inflammation, and immune evasion mechanisms. Further, the absence of specific surface markers that distinguish LSCs from normal hematopoietic stem cells, together with LSCs’ functional heterogeneity, complicates targeted treatment approaches. Immune dysfunction, including T cell exhaustion and immune suppression within the bone marrow niche contributes to therapy resistance. In this brief review, we aim to explore current challenges in AML therapy, focusing on LSC-driven resistance, immune evasion, and the need for innovative therapeutic strategies.</div></div>","PeriodicalId":50603,"journal":{"name":"Current Opinion in Pharmacology","volume":"82 ","pages":"Article 102526"},"PeriodicalIF":4.0,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143899387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Amongst the different types of DNA damage, double-strand breaks (DSBs) are the most harmful type of lesion that attenuates cellular proliferation. DSBs are repaired by two major pathways—homologous recombination (HR), and non-homologous end-joining (NHEJ) and in some cases by microhomology-mediated end-joining (MMEJ). Preference of the pathway depends on multiple parameters including site of the DNA damage, the cell cycle phase and topology of the DNA lesion. Deregulated repair response contributes to genomic instability resulting in a plethora of diseases including cancer. This review discusses the different molecular players of HR, NHEJ, and MMEJ pathways that control the switch among the different DSB repair pathways. We also highlight the various functions of chromatin modifications in modulating repair response and how deregulated DNA damage repair response may promote oncogenic transformation.</div></div>","PeriodicalId":50603,"journal":{"name":"Current Opinion in Pharmacology","volume":"80 ","pages":"Article 102496"},"PeriodicalIF":4.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142900094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
