Abstract
Acute Myeloid Leukemia (AML) represents only 1% of all cancers, despite being the most frequent type of leukemia [1]. Multiple genetic pathways are associated with AML, causing various changes in genetic transcription, apoptosis, chromatin remodeling, and protein levels. One such pathway, the JAK-STAT pathway, governs cellular proliferation, differentiation, and apoptosis, and is linked to both AML and myeloproliferative neoplasms due to mutations [2]. The JAK V617F mutation is the most common mutation in this pathway, occurring in about 50% of Essential Thrombocythemia (ET) patients, as described in this report [2]. While rare, transformation of Essential Thrombocythemia (ET) to AML occurs in 1-4% of cases [3]. This report presents a case of AML in a 76-year-old male with a medical history of ET. Following an abnormal peripheral blood smear, bone marrow biopsy confirmed the diagnosis. The current report aims to emphasize the significance of regular screening and monitoring for patients with long-standing Essential Thrombocythemia (ET), especially those under suppressive therapy. The transformation of ET to acute leukemia is associated with an unfavorable prognosis, underscoring the importance of early diagnosis. Therefore, this case serves to draw attention to the criticality of timely intervention through routine follow-up to achieve optimal outcomes for patients with ET.
