Preoperative Stratification of Transsphenoidal Pituitary Surgery Patients Based on Surgical Urgency.

BACKGROUND: Currently, there is no prioritization scale available to distinguish those patients with pituitary tumors who require urgent surgical intervention from those who are candidates for elective treatment.

OBJECTIVE: To develop a classification system that can help primary care physicians, endocrinologists, neurosurgeons, ancillary support staff, and hospital administrators identify high-priority surgical candidates.

METHODS: An expert international panel of clinicians consisting of endocrinologists and neurosurgeons who are involved in the diagnosis and management of sellar disease was convened. The panel retrospectively reviewed individual experiences, including a cohort of patients operated upon for pituitary related disease at the Brigham and Women's Hospital from January 2008 to November 2015. A risk stratification schema was developed to streamline patient care pathways.

RESULTS: We identified 4 groups of surgical candidates with varying levels of risk, and then assigned treatment timelines and different differential diagnoses to each. The 4 groups were as follows: group A: urgent-immediate; group B: prompt-initiate treatment within 1 to 2 weeks; group C: soon-initiate treatment within 3 months; group D: elective-as soon as indicated. Among 472 patients treated at Brigham and Women's Hospital for pituitary adenomas, each was assigned to 1 of the 4 predetermined subgroups: group A, 6.8%; group B, 30.1%; group C, 31.1%; group D, 32.0%.

CONCLUSIONS: We developed a risk stratification schema that may serve as a platform to streamline care to the patients at highest risk. The expert opinions presented provide a basis for future studies regarding the risk prioritization of patients.
