About
The purpose of this study is to compare the efficacy and safety of different doses of sirolimus in the maintenance treatment of kaposiform hemangioendothelioma.
Full description
Kaposiform hemangioendothelioma (KHE) is a rare aggressive vascular neoplasm that occurs predominantly in infancy or early childhood, with an incidence of approximately 0.071/100,000. Currently, sirolimus is a promising treatment modality for KHE. Most scholars consider sirolimus blood concentration of 5-15 ng/ml to be an effective therapeutic concentration, while 10-15 ng/ml is the most commonly used blood concentration. However, long-term higher dose sirolimus treatment can cause some common adverse effects, such as oral mucositis which affects the quality of life of the patient. Finer control of the plasma concentration of sirolimus may contribute to the efficacy of treatment and reduce the incidence of complications. Previous studies have found good efficacy of low-dose sirolimus maintenance treatment for KHE. However, there is no high-level evidence to support this treatment strategy. Therefore, we conducted this study to find out whether an early reduction in sirolimus dose would benefit the prognosis of the patients.
