Nedaplatin-induced syndrome of inappropriate secretion of antidiuretic hormone: A case report and review of the literature.

ABSTRACT

BACKGROUND: Syndrome of inappropriate secretion of antidiuretic hormone (SIADH) is relatively common in several cancers, such as small cell lung cancer. However, nedaplatin-induced SIADH is rare. We describe a case of SIADH mediated by nedaplatin. CASE SUMMARY: A 54-year-old female with nasopharyngeal carcinoma was treated with nedaplatin and developed severe hyponatremia due to SIADH. The side effects were successfully treated by fluid restriction and sodium supplementation. CONCLUSION: This case report highlights the importance of cautiously treating life-threatening hyponatremia in patients treated with nedaplatin.
