Streptozocin and o,p'DDD in the treatment of adrenocortical cancer patients : long-term survival in its adjuvant use

• BACKGROUND:To evaluate the efficacy of streptozocin and o.p'DDD (SO) in adrenocortical cancer (ACC) patients since other chemotherapeutic regimens have limited effects.PATIENTS AND METHODS:We performed a phase II study with SO therapy in 40 ACC patients (median age 44 years). Oral o,p'DDD administration (1-4 g/d, every day) was given together with intravenous streptozocin (1 g/d for five days, thereafter 2 g once every three weeks). 5HT3-receptor blocker was used as standard premedication for streptozocin.RESULTS:The SO therapy was found to have significant effects on disease-free interval (P = 0.02) as well as on survival (P = 0.01) in adjuvantly treated cases (n = 17) in comparison to the patients who did not get any therapy after complete resection (n = 11). Complete or partial response was obtained in 36.4% of patients with measurable disease (n = 22). The overall two-year and five-year survival rates were 70% and 32.5%, respectively. The presence of metastases at diagnosis was identified as a poor prognostic factor (P = 0.02).CONCLUSIONS:The present study necessitates further randomized clinical study of SO therapy in the treatment of ACC, mainly as adjuvant treatment immediately after curative intended surgery, and could be developed into a regular treatment regimen.
