A Clinical, Endocrinological, and Morphological Study of Pituitary Tumor Recurrence

Depending on the surgical approach, involving either total or subtotal extirpation of pituitary tumors, the recurrence rates have varied from 10.4% (intra- and suprasellar tumors without parasellar enlargement) to 35% (large tumors with parasellar configuration) in patients examined by us (Rauhut et al. 1986). In the literature there are many reports of a high risk of tumor recurrence in cases of a primary supra- and parasellar tumor configuration with infiltration of the neighboring structures (Fahlbusch et al. 1978; Guiot 1978; Wilson 1984).
