Acute spontaneous tumor lysis syndrome

Area of Science:

• Oncology
• Hematology
• Internal Medicine

Background:

• Tumor lysis syndrome (TLS) is a oncologic emergency characterized by rapid tumor cell breakdown.
• TLS is typically associated with hematologic malignancies and often triggered by cancer treatments like chemotherapy, steroids, or radiotherapy.
• Previous literature has primarily linked TLS development to therapeutic interventions.

Observation:

• An 83-year-old woman presented with weakness and anemia.
• She was diagnosed with Burkitt's leukemia/lymphoma.
• The patient subsequently developed acute tumor lysis syndrome.

Findings:

• This case represents the first reported instance of spontaneous tumor lysis syndrome in a patient with Burkitt's leukemia/lymphoma.
• The patient's TLS occurred without any preceding chemotherapy, steroids, or radiotherapy.
• This finding contrasts with the established understanding of TLS being treatment-induced.

Implications:

• The spontaneous occurrence of TLS suggests a need to reconsider the diagnostic criteria and etiological factors for this syndrome.
• Clinicians should be aware of the possibility of spontaneous TLS, even in the absence of treatment, particularly in patients with hematologic malignancies.
• Further research is warranted to elucidate the mechanisms underlying spontaneous TLS and identify potential predictive markers.
