Objective:

To present a novel case of hypouricemia associated with adjuvant imatinib therapy in a patient with intestinal GIST.

Key Findings:
  • The patient exhibited a persistent decline in serum uric acid levels during imatinib therapy, reaching a low of 96 μmol/L, below the normal range.
  • Post-treatment, serum uric acid levels normalized after discontinuation of imatinib.
Interpretation:

This case suggests that hypouricemia may be an underrecognized adverse effect of imatinib therapy in patients with GIST, highlighting the need for clinician awareness.

Limitations:
  • The case is singular and may not represent a broader trend.
  • Long-term effects and mechanisms of imatinib-induced hypouricemia require further investigation.
  • The findings may not be generalizable due to the singular nature of the case.
Conclusion:

Clinicians should be aware of the potential for hypouricemia in patients undergoing imatinib treatment for GIST, as it may not be routinely monitored and could have clinical implications.
