Leukemia is a serious type of blood cancer that requires early diagnosis and treatment. The following case illustrates the disease and its management.

A 19-year-old girl was brought to the emergency department at VishwaRaj Hospital, she had been experiencing severe joint pain and persistent high-grade fever for the past two weeks, along with multiple episodes of vomiting over the last 3–4 days. Additionally, she reported prolonged menstrual bleeding lasting eight days. On examination, she appeared pale and fatigued, with palpable swelling in the neck and red petechial spots on her lower limbs.

Initial blood tests revealed severe anemia (low hemoglobin), thrombocytopenia (low platelet count), and marked leukocytosis (very high white blood cell count). A peripheral smear suggested the possibility of leukemia. Leukemias are cancers of the blood caused by genetic mutations that lead to uncontrolled growth of white blood cells. These abnormal cells crowd out normal blood cell production in the bone marrow, causing anemia, low platelets, and associated symptoms. The rapid proliferation of leukemic cells can also expand bone cavities, resulting in bone pain. Because these abnormal white blood cells are ineffective at fighting infections, patients are prone to persistent fevers and other infectious complications.

Further evaluation with a bone marrow biopsy and molecular tests confirmed a diagnosis of Acute Lymphoblastic Leukemia (ALL). She was admitted to an isolation ward at VishwaRaj Hospital and started on treatment. She underwent an 8-week induction chemotherapy, followed by two months of consolidation chemotherapy. Genetic testing revealed high-risk ALL, and she subsequently received a matched sibling donor stem cell transplant. One year post-transplant, she remains in complete remission, is doing well, and has resumed her college education.

Leukemias are generally classified into acute and chronic types:

Chronic Leukemias:

• Chronic Myeloid Leukemia (CML)
• Chronic Lymphocytic Leukemia (CLL)

Acute Leukemias:

• Acute Myeloid Leukemia (AML)
• Acute Promyelocytic Leukemia (APL)
• Acute Lymphoblastic Leukemia (ALL – T cell or B cell)
• Other mixed leukemias

Warning signs that may suggest a blood malignancy (especially when occurring together) include:

• Persistent fever with unexplained weight loss
• Rapidly rising white blood cell counts
• New swellings in the neck or groin
• Significant spleen enlargement causing poor appetite and weight loss
• Easy bruising due to low platelet count or coagulation problems
• Strong family history of leukemia

Timely diagnosis is crucial for effective treatment of leukemia. Because treatment can be long, costly, and emotionally taxing, many families benefit from financial and social support from NGOs and other organizations. Comprehensive care requires a multidisciplinary team including hematologists/oncologists, infectious disease specialists, oncology nurses, a blood bank, intensive care support, social workers, clinical psychologists, and an institution committed to cancer care.
