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.

AbstractBackgroundThe Cavernous Hemangioma Exclusively Endonasal Resection (CHEER) staging system has become the gold standard for outcomes reporting in endoscopic orbital surgery for orbital cavernous hemangiomas (OCHs). A recent systematic review demonstrated similar outcomes between OCHs and other primary benign orbital tumors (PBOTs). Therefore, we hypothesized that a simplified and more comprehensive classification system could be developed to predict surgical outcomes of other PBOTs.MethodsPatient and tumor characteristics as well as surgical outcomes from 11 international centers were recorded. All tumors were retrospectively assigned an Orbital Resection by Intranasal Technique (ORBIT) class and stratified based on surgical approach as either exclusively endoscopic or combined (endoscopic and open). Outcomes based on approach were compared using chi‐squared or Fisher's exact tests. The Cochrane‐Armitage test for trend was used to analyze outcomes by class.ResultsFindings from 110 PBOTs from 110 patients (age 49.0 ± 15.0 years, 51.9% female) were included in the analysis. Higher ORBIT class was associated with a lower likelihood of gross total resection (GTR). GTR was more likely to be achieved when an exclusively endoscopic approach was utilized (p < 0.05). Tumors resected using a combined approach tended to be larger, to present with diplopia, and to have an immediate postoperative cranial nerve palsy (p < 0.05).ConclusionEndoscopic treatment of PBOTs is an effective approach, with favorable short‐term and long‐term postoperative outcomes as well as low rate of adverse events. The ORBIT classification system is an anatomic‐based framework that effectively facilitates high‐quality outcomes reporting for all PBOTs.
