What are the results of treatment for adrenal cortical cancers?

In general, adrenal cortical cancers are curable only in cases where the entire tumor is removed at surgery. Unfortunately, these tend to be aggressive cancers. Even when complete surgical removal is performed, they have a tendency to come back. The likelihood of this happening after a complete surgical resection is dependent upon the stage of the tumor. The 5-year overall survival describes the percentage of patients who are alive at 5 years after cancer treatment. After total tumor removal for stage I and II adrenal cortical cancers, the 5-year overall survival rate is 40-60%. For stage III cancers, the 5-year overall survival is 20%. For stage IV patients, the 5-year overall survival is 10%. There is a small percentage of patients who have slow-growing adrenal cortical cancers that can take a number of years to progress. It is unclear why these adrenal cancers act differently than the majority of adrenal cancers; however, these cases explain why 10% of patients who have disease that has spread to other parts of the body at the time of diagnosis (stage IV) are still alive at 5 years after diagnosis, despite the generally aggressive nature of these cancers.
