Long-term disease-free survival after adrenalectomy for isolated colorectal metastases.

Metastasis to the adrenal glands occurs in approximately 16% of patients with metastatic colorectal carcinoma. Historically, these metastases are found at autopsy, but due to improved imaging and diagnostic techniques, many of these lesions are now discovered on routine follow-up imaging. In general, adrenal metastasis is an indicator of widespread disease, but in rare cases, isolated adrenal metastasis can be found. Although potential improvement in overall survival after adrenalectomy for isolated colorectal metastases has been reported, there has only been one long-term disease-free survivor reported. Here, we report a patient who is a 7-year disease-free survivor after adrenalectomy for an isolated colorectal metastasis.
