Is There a Role for Low Doses of Mitotane (o,p′-DDD) as Adjuvant Therapy in Adrenocortical Carcinoma?

1998
Four patients suffering from adrenocortical carcinoma were treated with low doses (1.5–2.0 g) of mitotane(o,p′-DDD) for the complete follow-up time following surgery (21–68 months). Treatment with mitotanewas started shortly after surgical removal of the tumor (three patients) or the tumor and multiple lung metastasis (one patient). No significant side effects or complications from the medication were noted. Two patients remain disease free after 57 and 21 months on treatment. A third patient died of an unrelated reason ( varicose veinbleeding) after 68 months on mitotanewithout evidence of tumor recurrence or metastasis. In the fourth patient, two lung metastasis were successfully removed after 48 months of follow-up. The patient is doing well and is disease free 6 months later. Though our series is too small to draw final conclusions, we suggest that low doses of mitotane, which are well tolerated, might offer prolonged disease-free survival in adrenocortical carcinoma. To be beneficial treatment has...
