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.
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.
This case report highlights the importance of cautiously treating life-threatening hyponatremia in patients treated with nedaplatin.
Core Tip: Nedaplatin has been shown to be an effective drug in a variety of cancers. Due to its wide application, it is important to pay attention to its side effects, especially rare side effects. Here, we report a case of a severe, rare syndrome of inappropriate secretion of antidiuretic hormone after initiating nedaplatin chemotherapy. Timely diagnosis, fluid restriction and sodium supplementation may be the most appropriate treatments.
