Ongoing preclinical research is expected to produce more targeted therapies, reducing the need for traditional chemotherapy, while also enhancing classification systems and patient prognostication. In newly diagnosed AML, the mainstay of induction still is 7+3 regimen. In unfit adults, combination of venetoclax and hypomethylating agent has emerged to be the standard of care. Introduction of FLT3 inhibitors with the 7 plus 3 regimen has improved outcomes in FLT3 mutant patients. IDH inhibitors have recently been approved for induction in medically unfit adult. Studies focusing on triplet regimen are underway. FLT3 inhibitors and IDH inhibitors have also been approved for Relapsed and Refractory AML. Menin inhibitors are another novel class of drugs which are currently being studied for both de novo as well as relapsed and refractory AML. For consolidation in fit patients, high dose cytarabine and Allogenic transplant are still the mainstay of treatment whenever feasible. FLT3 inhibitors have been studied as long term maintenance after allogenic stem cell transplantation. As potent regimens achieve high-quality remissions, the need for sensitive assays to detect measurable residual disease (MRD) and predict relapse risk will grow. MRD monitoring using flow cytometry and molecular methods have been effective with cytarabine-based treatments and will be crucial for venetoclax therapies. Eradicating MRD is a key goal for AML subsets, with research focused on targeted and immune- based therapies to eliminate MRD and understand relapse through clonal evolution. Allogeneic stem cell transplant is the most effective treatment for residual leukemia in resistant AML but is limited by toxicity and donor availability. Immune-based strategies, including antibodies and bispecific molecules, show promise in early trials, and safer cellular therapies could expand treatment options.</p>","PeriodicalId":10348,"journal":{"name":"Clinical Lymphoma, Myeloma & Leukemia","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143585116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MZLs typically have excellent long-term outcomes and often do not require immediate treatment. For asymptomatic patients, active surveillance (watch-and-wait) is the standard approach. However, exceptions exist. Asymptomatic patients with Helicobacter pylori-positive gastric MZL should receive antibiotic eradication therapy upon diagnosis. Similarly, asymptomatic patients infected with hepatitis C virus (HCV) should receive antiviral therapy. Surgical resection is generally not indicated. Involved-site radiotherapy (ISRT) is recommended for localized disease (20-24Gy, depending on the anatomical site). While higher doses are often needed for curative intent, very low-dose ISRT (2×2 Gy) can achieve long-term control and provide effective palliation with minimal toxicity when a definitive cure is not the goal. Symptomatic patients with advanced-stage disease may benefit from systemic rituximab-based treatment. Rituximab monotherapy is suitable for patients who cannot tolerate chemotherapy or prioritize a low-toxicity initial approach. The combination of rituximab with bendamustine or chlorambucil can result in longer response duration and progression-free survival, but not in improved overall survival, and may be preferred for severely symptomatic patients with advanced disease. More intensive doxorubicin-containing regimens, which are more toxic, should be reserved for patients with histological transformation, aggressive presentations, or bulky masses. Although data from clinical trials are limited, several new therapies have shown encouraging results, including bispecific antibodies, chimeric antigen receptor (CAR)-T cell therapy, and small molecules.
