Prognosis

UCD: The average length of survival after UCD diagnosis is greater than 10 years, and life expectancy is usually not changed by UCD.

MCD: The 5-year overall survival rate of HIV negative (presumed HHV8-negative) MCD was 65% in a 2012 case series published prior to the approval of anti-IL-6 therapy (1). A study in 2021 found a 75% 5-year overall survival rate among iMCD patients (2). There is reasonable hope that the survival rates are currently greatly improved due to the new breakthroughs in treatment (such as anti-IL6 blockade). The CDCN is currently leading a global patient research study to collect data to update these numbers. Patients can enroll at www.CDCN.org/ACCELERATE
