Patients with sellar masses (SM) undergoing transsphenoidal surgery (TSS) have a significant risk of transient or permanent endocrine dysfunction; therefore, in-hospital endocrinology consultation (IHEC) is recommended for these patients. However, routine assessment of all TSS patients by a specialized team is not feasible outside select centers. We developed an IHEC guide for TSS patients in December 2015 to identify those patients who would require perioperative IHEC. We con...

Introduction: While there is a significant risk of recurrence in nonfunctioning pituitary adenoma (NFPA) after surgery, it is challenging to predict which NFPAs will recur based solely on routine histopathology. To better understand markers of recurrence, we assessed the established tumor markers linked to aggressive tumor behavior including X-linked IAP (XIAP), the most potent inhibitor of the apoptosis protein family, vascular epithelial growth factor (VEGF) which facilitate...

Secondary hormonal deficiency (SHD) is common in patients presenting with nonfunctioning pituitary adenomas (NFA). NFA can either stain for various hormones or be non-hormone staining on immunocytochemistry. To date, no study has assessed the association between staining pattern of NFA and pattern of SHD at presentation. The Halifax Neuropituitary Program has been prospectively collecting comprehensive data on all neuropituitary patients in the province of Nova Scotia, Canada ...
