Background and Clinical Relevance: The association between acute myeloid leukemia (AML) and monoclonal gammopathy of undetermined significance (MGUS) is rare and likely coincidental, due to the similar epidemiology of these two blood disorders in older AML patients who are not eligible for intensive chemotherapy or aggressive treatment, as they can be excessively myelosuppressive. Such treatments include those containing venetoclax, an easy-to-use all-oral form of decitabine–cedazuridine (DEC-C), which is now available and approved for AML in addition to standard parenteral DNA methyltransferase inhibitors, which have been commonly used in routine clinical practice for about two decades in patients unsuitable for intensive chemotherapy (IC). Case Presentation: A 71-year-old woman developed a therapy-related acute myeloid leukemia (t-AML) seven years after the discovery of the plasma cell dyscrasia. She had carried an asymptomatic and non-progressing IgG-λ MGUS since 2019 while affected by breast cancer, which was cured with chemotherapy and radiotherapy. BM smear and trephine biopsy at the time of t-AML diagnosis showed 30% myelomonoblasts and 8% plasma cells, while SPEP showed the presence of 15 g/L of monoclonal protein. However, considering her age and other medical and personal history, the patient was found unsuitable for IC as well as venetoclax treatment because of the myelosuppressive effect of the therapy. Therefore, she received DEC-C oral monotherapy. After four DEC-C cycles, she achieved CR with hematological incomplete recovery (CRi). During DEC-C monotherapy, serum immunofixation (IF) and BM evaluations after 12 months of treatment showed gradual clearance of the IgG-λ paraprotein and BM plasma cells. Maintenance therapy with oral DEC-C is ongoing for 18 months after achieving CRi, without any signs of toxicity or infection. Conclusions: This report describes the first anecdotal case of t-AML responding to DEC-C with concomitant clearance of the paraprotein associated with MGUS.

Acute Myeloid Leukemia (AML) is a heterogeneous group of aggressive blood-related cancers that arise from the hematopoietic system, requiring specific treatments due to their genetic diversity and complexity. Artificial intelligence (AI) has emerged as a transformative technology in healthcare, with considerable potential to help manage AML. The application of AI approaches, such as Machine Learning (ML) models and Deep Learning (DL) algorithms, has been shown to aid risk stratification, diagnosis, treatment planning, and surveillance. This review highlights recent developments in AI applications for the personalized management of AML. We focus specifically on three major axes of personalization in AML: (1) the use of predictive models combining different data sources to improve prognostic assessment and guide risk-adaptive treatments; (2) prediction of treatment responses to various therapies based on data analysis; and (3) the use of AI for monitoring and adaptive trials in AML patients.

After many years of stagnation in the treatment of acute myeloid leukemia (AML), there is currently a rapid move towards personalized medicine. Improvements in molecular diagnostics, risk assessment tools, targeted therapies, overall patient fitness assessments, and quality-of-life assessments have significantly changed how patients are treated. Genetic and molecular analyses, risk and health assessments, and measurable residual disease (MRD) monitoring are now integral to the treatment plan for evaluating patient responses and recurrence. In this regard, lower-intensity treatments are provided to older or unfit individuals. On the other hand, younger patients are usually subjected to curative therapies such as intensive chemotherapy to induce remission. Depending on their fitness and disease risk, they can be considered for hematopoietic cell transplantation, which is done after close observation for MRD. In addition, newer therapeutic drugs and immunotherapy techniques are being applied for patient management. Tremendous strides have been made in improving the efficiency of treatment programs in the relatively new area of personalized AML therapy, with a focus on functionality.

Acute myeloid leukemias (AMLs) are heterogeneous hematologic cancers that occur prevalently in older patients as the result of a complex pathobiology. The clinical outcomes of older patients with AML, often unsuitable for intensive chemotherapy and allogeneic stem cell transplantation, are generally disappointing. However, recent advances in understanding molecular pathogenesis and other biological mechanisms recognized in AML development and progression have changed the treatment approach, especially for this particularly vulnerable category of patients. Indeed, non-intensive biologically tailored approaches, such as combining venetoclax with hypomethylating agents, have changed the therapeutic paradigm in this field. Moreover, other promising compounds and treatment strategies are currently under advanced clinical development. This article delves into the latest biological understanding and therapeutic advances in the clinical management of older AML patients into new conceptual frameworks that progressively transform the clinical practice in this challenging setting.
