Successful management of steroid‐resistant vascular tumors associated with the Kasabach–Merritt phenomenon using sirolimus

Vascular tumors associated with Kasabach–Merritt phenomenon (KMP) are life‐threatening and the mortality is as high as 10–30%. Steroids are considered the primary choice for drug therapy. However, there are many steroid‐resistant cases. In the present study, analyzed data are presented to support th...

Sumario:Vascular tumors associated with Kasabach–Merritt phenomenon (KMP) are life‐threatening and the mortality is as high as 10–30%. Steroids are considered the primary choice for drug therapy. However, there are many steroid‐resistant cases. In the present study, analyzed data are presented to support the use of sirolimus in clinical practise for the treatment of corticosteroid‐resistant vascular tumors with KMP in eight infants between June 2015 and April 2017 in a single hospital. The time to initial response was 6.8 ± 2.7 days. The average stabilization time for the platelet count was 19.1 ± 8.5 days. At the time of publication, the average duration of sirolimus treatment was 14.1 ± 4.0 months, and the average time for sirolimus treatment as a single agent was 12.6 ± 4.2 months. The side‐effects were tolerable and included oral ulcer, fever, pain, skin rash and transient ascension of serum transaminase and cholesterol. Our study indicated that sirolimus therapy is an effective and safe method for the treatment of corticosteroid resistant vascular tumors associated with KMP in infants.
