[Adrenocortical carcinoma: prognostic factors for local recurrence and indications for reoperation. A report on a series of 22 patients].

STUDY AIMS

The aim of this retrospective study was to identify prognostic factors on local recurrence in patients with adrenocortical carcinoma and to assess the effect of reoperations.

METHODS

From 1985 to 2001, 22 patients were operated for adrenocortical carcinoma. We evaluated the correlation between actuarial survival without local recurrence and tumor staging, Weiss criteria, mitotic index, extensive resection and Op'DDD therapy by univariate analysis. Then we evaluated the effect of reoperations on survival.

RESULTS

Local recurrence was observed in 7 patients and the 5-years actuarial survival without local recurrence was 50%. Tumor stage (I et II versus III et IV), Weiss criteria (< or = 6 criteria versus > 6) and mitotic index (< or = 20 mitoses/50 HPF versus > 20) affected survival without local recurrence. Extensive resection could reduce local recurrence rate. Op'DDD therapy was ineffective in prolonging survival without local recurrence. Four patients underwent repeat resections: 2 patients were still alive with disease free, 54 and 8 months after reoperations and 2 patients died, 19 and 25 months after reoperations. Three patients did not have repeat resection. They rapidly died within 8 months.

CONCLUSION

Pathologic features (tumor staging and mitotic index) affected local recurrence prognostic. But extensive resection to adjacent organs could facilitate complete resection tumor and reduce the local recurrence rate. Complete repeat resection of local recurrence can improve survival. The disabling effects of Op'DDD were important and its efficacy was not clear.
