The approximate 5-year survival rate for adrenocortical carcinoma is which of the following?

b. 20%–25%

The prognosis for adrenocortical carcinoma is not good. The overall 5-year survival rate is 20% to 25% for these malignancies. When there is localized disease at the time of surgery, the 5-year survival may be higher, in the 40% to 50% range. The true prognosis in childhood is not clear, but the data suggest a 2-year survival rate of about 20%.
