Acute Undifferentiated Leukemia (AUL)

Overview

Acute Undifferentiated Leukemia (AUL) is a very rare and aggressive type of blood cancer. It starts in the bone marrow, where blood cells are made, and causes the body to produce abnormal white blood cells. Unlike other types of leukemia, AUL cannot be clearly classified as either myeloid or lymphoid leukemia because the cancer cells do not show the usual markers that doctors use to identify these categories.

Common signs and symptoms

  • Persistent fatigue
  • Unexplained fevers
  • Night sweats
  • Easy bruising or bleeding
  • Bone or joint pain
  • Swollen lymph nodes, liver and spleen
  • Pallor

Diagnostic tests and procedures

  • Complete blood count (CBC) can reveal abnormalities in blood cell levels indicative of leukemia.
  • Peripheral blood smear to look for abnormal cells.
  • Bone marrow aspiration and biopsy to check for cancerous cells .
  • Imaging like X-rays or CT scans.

Treatment options

Chemotherapy

The primary treatment for AUL, using powerful medications to kill leukemia cells, typically administered in multiple phases.

Bone marrow transplant (BMT)

In certain cases to replace diseased bone marrow with healthy stem cells from a donor.

Supportive care

Including blood transfusions, antibiotics for infections, and other medications.

Prognosis

AUL is associated with a more challenging prognosis compared to other types of leukemia. Advancements in treatment options and supportive care have improved outcomes for many patients. Regular follow-up care is essential to monitor for potential complications or recurrence after treatment.
