Overview

Acute Leukemia is a malignancy of bone marrow myeloid and lymphoblastic precursor cells, in which these poorly differentiated hematopoietic cells proliferate rapidly. Hence, their accumulation would disrupt the performance of bone marrow to produce normal blood cells

Causes

AML and ALL are life-threatening diseases, which would result in death if left untreated. In the majority of cases, etiology is not apparent.

Common Causes of AML

• Gene mutations:FLT3, IDHI, IDH2, KRAS, DNMT3A, NPM1
• Chromosomal translocations, deletions, and inversions
• Benzene or radiation exposure chronically

Common Causes of ALL

• Radiation exposure:
• Genetic disorders; e.g., Down syndrome, ataxia-telangiectasia, Fanconi anemia
• Certain infections: e.g., HTLV-1

FIRE

A Focused Initial Rapid Evaluation (FIRE) should be performed to identify patients in need of immediate intervention.[5]

Boxes in red color signify that an urgent management is needed.

---

Obtain patient's medical history and focus on these signs and symptoms: ❑ Fatigue ❑ Weight loss ❑ Anorexia ❑ Lymphadenopathy ❑ Bone pain ❑ Bleeding ❑ Early satiety ❑ History of specific and chronic exposures such as alkylating agents, benzene, radiation, or previous chemotherapy Headache ❑ History of recurrent fever

Obtain a focused history: ❑ Onset ❑ Severity compared to previous episodes ❑ Possible causes ❑ ❑ ❑ Exacerbations in previous 1 year ❑

Examine the patient: ❑ [[]] ❑ [[]] ❑ A ❑ B ❑ C ❑ D ❑ E ❑ F

Order tests: ❑ Spirometry (FEV1, Peak expiratory flow PEF)* ❑ O2 saturation (pulse oximetry) ❑ Arterial blood gas (not routine) ❑ Order additional tests if needed

AA: ❑ B ❑ F ❑ G or H ❑ H
