[Factors influencing the recurrence of Cushing's disease treated by transsphenoidal surgery]

To explore factors influencing the recurrence of patients with Cushing's disease after transsphenoidal surgery.

We retrospectively analyzed the clinical data of 182 patients treated by transsphenoidal surgery with Cushing's disease in our department in PUMC Hospital from 1992 to 2002.

The recurrence rates were significantly different when patients had different radiological findings (P = 0.001), operative methods (P = 0.001), histological findings (P = 0.04), and postoperative cortisol levels (P = 0.02); however, such difference was not found in term of tumor size (P = 0.43).

Radiological findings, operative methods, histological findings, and postoperative cortisol estimates may be the factors influencing the recurrence of patients treated by transsphenoidal surgery.
