Extremely long survival in six patients despite recurrent and metastatic adrenal carcinoma.

OBJECTIVE: Adrenal cortical carcinoma (ACC) is an aggressive tumour with a high mortality. We describe six patients living 12-28 years despite recurrent and/or metastatic ACC. PATIENTS: The first patient presented in 1979 with an ACC of 8 cm. After resection, she developed seven recurrences for which she was treated with resection and/or mitotane (o,p'-DDD) treatment. The patient is still alive 28 years after diagnosis. The second patient presented with an ACC of 9 cm. After resection, the patient developed liver metastases, which were treated with o,p'-DDD. The patient is still alive 25 years after diagnosis. The third patient presented with an ACC of 12 cm. The tumour was resected followed by o,p'-DDD treatment. She had a local recurrence that was completely resected. She is still alive 18 years after diagnosis. The fourth patient presented with an ACC of 14 cm. After resection, adjuvant o,p'-DDD was started. Subsequently, the patient developed two recurrences, which were resected. He is still alive 17 years after the initial diagnosis. The fifth patient presented with an ACC of 10 cm. After diagnosis, she developed lung metastasis, which were treated with o,p'-DDD and chemotherapy. The patient is still alive with slowly progressive disease 12 years after diagnosis. The sixth patient presented with an ACC of 7 cm. After resection, she developed four recurrences, which were resected. The patient is still alive 28 years after diagnosis.
CONCLUSION: Some patients can have an extremely long survival of ACC, despite recurrent disease and metastases. The mainstay of therapy in our patients was repeated surgery and o,p'-DDD.
