Abstract

Whereas benign adrenocortical tumors are frequent in the population, adrenocortical carcinoma (ACC) is a rare cancer. Significant advances in the understanding of the pathogenesis of sporadic ACCs have been possible through the study of hereditary syndromes responsible for ACCs. The genetic alterations involved in these syndromes have also been found in sporadic ACCs. Several specific genes have been shown to be altered in sporadic ACCs. Despite these progresses, the underlying sequence(s) of events remains to be elucidated. Progressive transformation of a normal tissue into a benign tumor and ultimately into a carcinoma occurs via accumulation of genetic and epigenetic alterations. Likewise, a multistage model has been proposed for the adrenal tumor development. This review summarizes the molecular alterations likely involved in the multistage tumorigenesis and describes a mouse model which allows us to evaluate the effect of individual genes or combination of genes in the development of adrenocortical tumors.
