OBJECTIVE Frailty is a known predictor of adverse outcomes in pituitary surgery, yet its impact regarding craniopharyngioma remains unclear. The authors assessed preoperative frailty, measured by the 11-factor modified frailty index (mFI-11), and its association with perioperative morbidity among adult patients undergoing craniopharyngioma surgery. METHODS Using the Registry for Adenomas of the Pituitary and Related Disorders (RAPID) database, the authors performed a retrospective cohort study of the records of patients ≥ 18 years of age who underwent craniopharyngioma surgery between June 2007 and November 2024. Patients were stratified into the following categories according to their numeric mFI-11 score: fit (scores 0 and 1), managing well (scores 2 and 3), and mildly frail (scores 4–6). Primary outcomes included hospital length of stay (LOS) and discharge disposition. Secondary outcomes included 90-day readmission, surgical outcomes, and complications. Multivariable analyses were performed to identify independent predictors of hospital LOS and non-home discharge, adjusting for age, surgeon experience, American Society of Anesthesiologists class, complications, and surgical approach. RESULTS Among 278 patients (221 fit, 43 managing well, 14 mildly frail), higher-frailty patients were older (mean age 47.8 ± 16.1 years in fit vs 60.1 ± 12.5 years in managing well vs 67.6 ± 8 years in mildly frail, p < 0.001) and more likely to present urgently (24.2% vs 36.4% vs 78.6%, p = 0.001). Gross-total resection was achieved less frequently in frail patients (44.8% vs 24.3% vs 23.1%, p = 0.030). Overall complication rates were similar; however, increasing frailty was associated with higher rates of postoperative mortality (0% vs 2.8% [1/36] vs 7.7% [1/13], p = 0.018), pneumonia (0.5% [1/195] vs 2.8% [1/36] vs 15.4% [2/13], p = 0.006), and reintubation (2.6% [5/195] vs 2.8% [1/36] vs 30.8% [4/13], p = 0.002). Higher frailty was associated with a stepwise rise in median [IQR] LOS (5 [3–8] days vs 7 [4–12] days vs 13 [6.5–21.8] days, p < 0.001) and remained an independent predictor of extended LOS on multivariable analysis (β = 1.729 per point, p = 0.006). Rates of non-home discharge showed a similar pattern (9.2% vs 30.0% vs 64.3%, p < 0.001), with frailty independently predicting non-home discharge (OR 2.352, 95% CI 1.527–3.822). Unplanned 90-day readmission rates were significantly higher in the mildly frail cohorts (22.5% vs 45.7% vs 53.8%, p = 0.002). CONCLUSIONS The mFI-11 scores independently predicted perioperative morbidity following craniopharyngioma resection. Incorporating frailty screening into preoperative screening may improve risk stratification, family and patient counseling, and discharge planning.

BACKGROUND AND OBJECTIVES: Perioperative protocols facilitate earlier discharge without compromising safety in nonfunctioning pituitary adenomas, but no large multicenter studies in the United States have investigated protocols regarding Cushing disease (CD). We sought to characterize perioperative protocols and how their implementation influences clinical outcomes in patients with CD. METHODS: A retrospective analysis was conducted using data from the Registry of Adenomas of the Pituitary and Related Disorders consortium comprising 13 US academic pituitary centers. Institutions were surveyed regarding perioperative procedures for patients undergoing transsphenoidal tumor resection for CD. The impacts of institutional procedures and approaches to implementation on length of stay (LOS) and unplanned 90-day readmission were evaluated. RESULTS: Thirteen institutions contributed survey responses and clinical data for a total of 832 patients meeting inclusion criteria. Ten (76.9%) institutions reported having a postoperative protocol, 9 (69.2%) used a formal document to outline their protocol, and 3 (23.1%) had protocols implemented into hospital policy. Mean LOS was significantly reduced in centers with an established protocol (3.14 vs 3.42 days, P = .032), and more so with a formal document (3.10 vs 3.48 days, P = .001) or hospital policy (2.72 vs 3.36 days, P < .001). Patients treated after protocol implementation experienced shorter LOS ( P < .001). Other factors associated with reduced LOS were presence of a separate CD pathway, intraoperative checklist specific to pituitary surgery, non-narcotic pain regimen, Foley removal order, dedicated outpatient advanced practice provider follow-up, and target discharge date ≤2 days. Intraoperative checklist ( P = .045), non-narcotic pain regimen ( P = .048), nasal packing ( P = .005), and 1-day target discharge date ( P = .032) were important factors against readmission. Compared with microscopic surgery, endoscopic surgery was associated with shorter LOS but increased readmission odds. CONCLUSION: This is the first multicenter study to illustrate that implementation of perioperative protocols is associated with a reduction in LOS and readmission risk in patients with CD.

Abstract Craniopharyngiomas are rare parasellar tumors, and papillary craniopharyngiomas (PCPs) represent 8 to 20% of cases. Interim analysis of retrospective data collected from the Registry of Adenomas of the Pituitary and Related Disorders (RAPID). Fourteen U.S.-based academic skull base centers between 2011 and 2023. Patients with PCPs. Demographic, imaging, surgical, and outcome variables. Ninety-nine patients with PCPs were included. The mean age was 51.8 ± 14.7, and 57.6% were male. Most tumors showed mixed cystic/solid components (67.5%), were transinfundibular (50.0%), and were treated with an endoscopic endonasal approach (74.5%), with 51.1% demonstrating gross total resection (GTR). Pituitary stalk was preserved in 51.9%. Permanent arginine vasopressin deficiency was seen in 67.1% and was associated with pituitary stalk sacrifice (p = 0.003). Cerebrospinal fluid leak was the most common nonendocrine postsurgical, 30-day complication (9.1%), reason for return to the operating room (3.1%), and reason for 90-day readmission (8.1%). Most patients (63.9%) received no adjuvant therapy; GTR was associated with decreased radiotherapy use (p = 0.0001). BRAFV600E mutation was detected in 64/69 tumors tested, although only one patient was treated with a BRAF inhibitor. A mean follow-up of 12.3 ± 14.6 months was seen for the group. RAPID consortium enabled the largest real-world clinical information dataset for PCPs. Early findings support that GTR and stalk preservation are important to outcomes. Iterative analysis and discussion of data led to the generation of a framework for future studies to fully leverage the capabilities of multicenter registries.

Abstract Purpose: Craniopharyngiomas are rare parasellar tumors, and papillary craniopharyngiomas (PCP) represent 8-20% of cases. We assessed surgical outcomes of these very rare tumors among patients treated in the last decade. Methods: Retrospective data from the Registry of Adenomas of the Pituitary and Related Disorders (RAPID) were used to evaluate patients with PCP treated between 2011 and 2023 at 14 US-based academic skull base centers. Demographic, imaging, surgical, and outcome variables were analyzed. Results: Ninety-nine patients with PCP were included. Mean age was 51.8±14.7 and 57.6% were male. Most tumors showed mixed cystic/solid components (67.5%), were trans-infundibular (50.0%), and were treated endoscopically (74.5%), with 51.1% demonstrating gross total resection (GTR). Pituitary stalk was preserved in 51.9%. Permanent arginine vasopressin deficiency was seen in 68.8% and was associated with pituitary stalk sacrifice (p=0.02). Cerebrospinal fluid leak was the most common nonendocrine postsurgical, 30-day complication (9.1%), reason for return to the operating room (3.1%), and reason for 90-day readmission (8.1%). Return to the operating room was associated with discharge to a skilled nursing or rehabilitation facility (p=0.0001). Most patients (63.9%) received no adjuvant therapy; GTR was associated with decreased radiotherapy use (p=0.0001). BRAFV600E mutation was detected in 64/69 tumors tested, although only 1 patient was treated with a BRAF inhibitor. Conclusion: To our knowledge, the RAPID consortium enabled the largest real-world clinical information dataset for PCP. Our data can be used as a benchmark for short-term surgical outcomes. Longer-term follow-up studies are needed to understand how to optimize outcomes from each treatment modality.
