We review the importance of monocytic differentiation and induction in non-APL (acute promyelocytic leukemia) variants acute myeloid leukemia (AML), a malignancy characterized by proliferation immature cells. Even though cellular block is fundamental characteristic, AML cells can show limited signs differentiation. According to French-American-British (FAB-M4/M5 subset) World Health Organization (WHO) 2016 classifications, morphological expression specific molecular markers involved communication adhesion. Furthermore, FAB-M4/M5 patients are heterogeneous with regards cytogenetic genetic abnormalities, does not have any major prognostic impact for these when receiving conventional intensive cytotoxic therapy. In contrast, decreased susceptibility Bcl-2 inhibitor venetoclax, this seems be due common characteristics involving mitochondrial regulation metabolism survival, including dependency on compared other patients. Thus, inhibition only depend general resistance/susceptibility mechanisms known from therapy but also target itself or context target. cell status associated targeted therapies (e.g., CDK2/4/6 bromodomain inhibition), part antileukemic effect several anti-AML therapies. Differentiation-associated may thus become important future implementation human AML.

Abstract Background Acute myeloid leukaemia (AML) is a heterogeneous disease characterised by distinct French–American–British (FAB) classifications and molecular mutations. Understanding how these biological markers relate to drug responses crucial for refining therapeutic approaches. Methods We examined sensitivity patterns in 186 AML patients using selective Drug Sensitivity Scores (sDSS), analysing data from 515 commercially available chemotherapeutic targeted oncology agents. was analysed across various FAB subtypes (M0, M1, M2, M4, M4 eos, M4/M5, M5) important mutations (NPM1, FLT3, FLT3‐ITD, FLT3‐TKD KIT). Results Navitoclax showed greater effectiveness M0, M2 subtypes. NPM1 were linked increased multiple FLT3‐ITD associated with significant responsiveness PI3K/mTOR inhibitors. Analysis of combinations revealed complexities agents, often leading reduced but providing insights into successful pairings. Conclusions The findings underscore the necessity personalised strategies AML, advocating treatment protocols that integrate individual mutation profiles enhance patient care improve clinical outcomes.
