Clinical Significance of Tumor-Related Edema of Optic Tract Affecting Visual Function in Patients with Sellar and Suprasellar Tumors.

Objective: Preoperative tumor-related edema of the optic tract (EOT) is often found along the white matter tract of the visual system. However, the relationship of EOT with visual function and outcome remains unclear. Therefore we aimed to elucidate whether the presence of EOT is associated with visual outcome in patients with sellar and suprasellar tumors.

Impact of maximal safe resection on the clinical outcome of adults with craniopharyngiomas.

Recent studies suggest that subtotal resection (STR) followed by adjuvant radiation therapy is an appealing alternative to gross total resection (GTR) for craniopharyngioma, as STR provides similar tumor control without the associated endocrinological and behavioral morbidity. We have examined the impact of maximal safe resection on the clinical outcome of patients with craniopharyngioma. A total of 90 patients underwent surgical resection of craniopharyngioma at a single institution between January 1995 and April 2009.
