Overall survival or disease-free survival was calculated and survivalcurves were plotted by Kaplan-Meier and compared by log-rank test. Harzardratios（HRs） with their 95% confidenceintervals（CIs） were calculated by univariate and multivariate Coxregression model.【Results】The study included 20 adult patients with ACC， with a median follow-up of 13months （6~73 months）. The mean survival time of those patients was 49.2 months（6~73months），with a 1-year survival rate of 70.0%. The results of multivariate Coxregression analysis revealed that the presense of cortisol hypersecretion（HR=23.60，95%CI：2.49-223.79，P=0.006） and hypokalemia（HR=23.60，95%CI：2.49-223.79，P=0.006）were predictors of poorprognosis of ACC. Moreover，in 18 patients with completely resected ACC，the presense of hypokalemia resulted in a worse disease-free survival.【Conclusion】The presense of cortisol hypersecretion and hypokalemiaare independent risk factors associated with poorprognosis of ACC in adults.​
