This article discusses the use of an endoscopic endonasal approach (EEA) for the resection of anterior skull base tumors in young children. Traditionally, these tumors have been treated with open craniotomy, but the EEA has become more common in pediatric patients. The article reviews a retrospective study of ten patients aged 5 or younger who underwent EEA for tumor resection. The results showed that the EEA was safe and effective, with successful reconstruction of the skull base in all cases. Further research is needed to evaluate the EEA in this population.

This article examines the impact of frailty on postoperative outcomes in patients undergoing open and endoscopic resection of olfactory groove meningiomas. The study included 19 patients, with 6 undergoing endoscopic resection and 13 undergoing open craniotomy. The results showed that frailty metrics, such as the Charlson Comorbidity Index and modified 5-item frailty index, were not associated with postoperative complications or poor neurologic outcomes. However, a prior history of cranial radiation was associated with complications in open cases. The study suggests a need to reconsider traditional frailty measures in these surgical procedures.

ENDOSCOPIC surgery , *SOCIOECONOMIC status , *INCOME - Abstract
This article explores the impact of patient demographics and socioeconomic status on surgical outcomes in endonasal endoscopic pituitary surgery. The study reviewed 187 patients who underwent this surgery between 2017 and 2019. The findings revealed that male patients were more likely to have larger tumors and higher comorbidity scores, while Hispanic patients had smaller tumors and lower comorbidity scores. Black patients experienced longer hospital stays, higher costs, and higher rates of readmission, regardless of income. These results suggest that racial health disparities are not solely due to socioeconomic status and emphasize the importance of considering social determinants of health in clinical practice.

Background Sinonasal undifferentiated carcinoma (SNUC) is a rare, aggressive malignancy with a poor prognosis, and multimodal therapy is the standard of care. We sought to characterize treatment delays in SNUC managed with surgery and adjuvant radiation and to determine the impact on survival using the National Cancer Database (NCDB). Methods This was a retrospective, population-based cohort study of patients with SNUC between 2004 and 2016 in the NCDB. The intervals of diagnosis to surgery (DTS), surgery to radiation (SRT), and radiation duration (RTD) were examined. Recursive partitioning analysis (RPA) was performed to identify the variables with the greatest impact on survival. The association between treatment delay and overall survival (OS) was then assessed using multivariate Cox proportional hazards regression. Results Of 173 patients who met inclusion criteria, 65.9% were male, average age at diagnosis was 56.6 years, and 5-year OS was 48.1%. Median durations of DTS, SRT, and RTD were 18, 43, and 46 days, respectively. Predictors of treatment delay included Black race, government insurance excluding Medicare/Medicaid, and positive margins. RPA-derived optimal thresholds were 29, 28, and 38 days for DTS, SRT and RTD, respectively. On multivariate analysis, positive margins (hazard ratio [HR]: 4.82; 95% confidence interval [CI]: 2.28–10.2) and DTS less than 29 days (HR: 2.41; 95% CI: 1.23–4.73) were associated with worse OS. Conclusion Our results likely reflect the aggressive nature of the disease with surgeons taking more invasive disease to the operating room more quickly. Median treatment intervals described may serve as relevant national benchmarks. [ABSTRACT FROM AUTHOR]

Objectives Although adjuvant radiotherapy may be indicated in patients with sinonasal squamous cell carcinoma (SNSCC) following primary surgery, some patients choose to forgo recommended postoperative radiation therapy (PORT). This study aimed to elucidate factors associated with patient refusal of recommended PORT in SNSCC and examine overall survival. Methods Retrospective analysis of patients with SNSCC treated with primary surgery from the National Cancer Database diagnosed between 2004 and 2016. A multivariable logistic regression model was created to determine the association between clinical or demographic covariates and likelihood of PORT refusal. Unadjusted Kaplan–Meier estimates, log-rank tests, and a multivariable Cox proportional hazard model were used to assess overall survival. Results A total of 2,231 patients were included in the final analysis, of which 1,456 (65.3%) were males and 73 (3.3%) refused recommended PORT. Patients older than 74 years old were more likely to refuse PORT than those younger than 54 (odds ratio [OR] 3.43, 95% confidence interval [CI]: 1.84–6.62). Median survival among the entire cohort, those who received recommended PORT, and those who refused PORT was 83.0 months (95% CI: 74.6–97.1), 83.0 months (95% CI: 74.9–98.2), and 63.6 months (95% CI: 37.3–101.4), respectively. Refusal of PORT was not associated with overall survival (hazard ratio: 0.99, 95% CI: 0.69–1.42). Conclusions PORT refusal in patients with SNSCC is rare and was found to be associated with several patient factors. The decision to forgo PORT is not independently associated with overall survival in this cohort. Further study is required to determine the clinical implications of these findings as the treatment decisions are complex. [ABSTRACT FROM AUTHOR]

Objective This study aimed to provide information regarding the prognosis of patients presenting with metastatic anterior skull base malignancies based upon histology and site of distant metastasis (DM). Patients and Methods The National Cancer Database was queried for patients with anterior skull base malignant neoplasms with DM. Outcomes Prognosis was compared between site of DM and tumor histologies. A multivariable Cox proportional hazards model was used to identify prognostic factors for overall survival (OS). Results A total of 481 patients were identified. Lung was the most common site of DM (24.9%), followed by bone (22.2%), liver (5.6%), and brain (2.5%). Lung was the most common site for squamous cell carcinoma (SCCa) (28.3%), melanoma (37.7%), and adenoid cystic carcinoma (ACC; 31.4%). The median survival for patients presenting with metastatic disease regardless of tumor histology was 9.0 months (95% confidence interval [CI]: 8.2–10.3), and patients with metastasis to the liver had the best median survival at 15.5 months (95% CI: 10.5–25.6). The median survivals for the most common histologies, SCCa, melanoma, and ACC were 8.2 months (95% CI: 5.5–10.2), 10.5 months (95% CI: 8.7–14.1), and 15.0 months (95% CI: 11.1–61.1), respectively. Multivariable analysis demonstrated worse overall survival (OS) for older patients, higher Charlson-Deyo comorbidity scores, and tumors with higher grade and T stage. Compared with metastasis to bone, lung metastasis had better OS on multivariable analysis (hazard ratio [HR]: 0.70, 95% CI: 0.51–97). Adenoid cystic carcinoma had improved OS compared with SCCa (HR: 0.62, 95% CI: 0.39–99). Conclusion Tumor histology, metastatic sites, and several disease factors affected prognosis in anterior skull base malignancies with DM. [ABSTRACT FROM AUTHOR]

Objective Radiation therapy represents an uncommon but important component of treatment plans for some pituitary adenomas (PAs). Although radiation therapy has been used to treat pituitary adenomas for over a century, general trends in the usage of radiation therapy for this purpose have not been reviewed. Additionally, there are few large studies evaluating how radiation therapy is used for the treatment of these benign tumors. Investigating these trends and identifying any variations in radiation therapy utilization would help to better inform treatment decisions and improve patient outcomes. Design Present study is a retrospective analysis of cases using the National Cancer Database. Setting The research was organized at a tertiary academic medical center. Participants Patients were diagnosed with pituitary adenoma between 2004 and 2014 within the National Cancer Database (NCDB). Methods Temporal trends in the usage of radiation therapy to treat pituitary adenoma were analyzed through a retrospective analysis of 77,142 pituitary adenoma cases from the NCDB between 2004 and 2014. Univariate and multivariate analyses were to examine the relationship between patient, tumor, and treatment factors, and the incorporation of radiation therapy into the treatment of pituitary adenomas. We adjusted for potential confounders such as age, sex, race, comorbidity score, facility type, and year of diagnosis. Results A total of 77,142 patients met inclusion criteria. Inclusion of radiation therapy in pituitary adenoma treatment was 8.0% in 2004 and steadily declined to a low of 3.1% in 2014. Overall, patients were less likely to receive radiation for their pituitary adenoma over time (p < 0.001). Similarly, patients were found to be less likely to receive any type of treatment for PA over time (p < 0.001). Multivariable evaluation found patients who were female, between 54 and 64 years of age, or treated at either a Comprehensive Community Cancer Program or an Integrated Network Cancer Program were more likely to receive radiation as part of their pituitary adenoma treatment (p < 0.001, odds ratio [OR] = 2.01, confidence interval [CI]: 1.54–2.63; p < 0.001, OR = 1.84, CI: 1.38–2.44, respectively). Patients were less likely to receive radiation for their PA if they were African American (p < 0.001, OR = 0.81, CI: 0.72–0.91). Logistic regression also identified a progressive increase in the likelihood of receiving radiation after a PA diagnosis with increasing tumor size starting with microscopic tumors, peaking at 4 to 5 cm (p < 0.001; OR = 15.57; CI: 12.20–19.87). Conclusion In this sample of pituitary adenoma patients treated at NCDB institutions between 2004 and 2014, we found a steady decline in the incorporation of radiation therapy in treatment, as well as in the use of any type of intervention for PA treatment, suggesting a rise in noninterventional observation of PA.

Objective Surgical resection is widely accepted as a critical component for definitive treatment of sinonasal mucosal melanoma. Systemic immunotherapy, including multiple newer agents, has been used to treat metastatic or unresectable disease. In this study, we examine its efficacy in locoregional control when used in conjunction with surgical resection for primary mucosal lesions. Design Present study is a retrospective review of all patients at a tertiary academic medical center with primary sinonasal mucosal melanoma and distant metastatic disease. Results A total of four patients were identified. In all cases, patients were treated with a combination of surgical resection of the primary tumor and systemic immunotherapy. Three patients were initially treated with surgery at the primary site followed by immunotherapy for distant metastases. Response to immunotherapy at the sites of primary and metastatic disease was seen in two patients. All four patients developed progression or recurrence at the primary site following initiation of immunotherapy for which they underwent surgical resection. One patient remains in follow-up without evidence of disease 20 months after initial treatment; three succumbed to the disease at 135, 37, and 16 months after initial treatment. Conclusion Surgical resection for local control plays a critically important role in the treatment of sinonasal mucosal melanoma regardless of the presence of metastases and whether immunotherapy will be given. This case series suggests that, though immunotherapy may demonstrate efficacy in managing distant disease, surgery should remain the first-line treatment for the primary site. [ABSTRACT FROM AUTHOR]

Background Sinonasal adenocarcinoma (SNAC) is a rare malignancy arising from mucus-secreting glandular tissue. Limited large-scale studies are available due to its rarity. We evaluated SNAC in the National Cancer Database (NCDB), a source that affords multi-institutional, population studies of rare cancers and their outcomes. Methods The NCDB was queried for adenocarcinoma in the sinonasal tract. Multivariate analyses were performed to evaluate for factors contributing to overall survival (OS). Results A total of 553 patients were identified. The cohort was composed of 59.3% males. The nasal cavity was the most common primary site, representing 44.1% of cases. About 5.7% of patients presented with nodal disease, while 3.3% had distant metastases. About 40.6% of cases presented with stage IV disease. About 73.5% of patients underwent surgery, 54.2% received radiation therapy, and 27.7% had chemotherapy. Median OS was 71.7 months, while OS at 1, 2, and 5 years was 82, 73.0, and 52%, respectively. On multivariate analysis, advanced age (hazard ratio [HR]: 1.04; 95% confidence interval [CI]: 1.02–1.05), Charlson–Deyo score of 1 (HR: 1.99; 95% CI: 1.20–3.30), advanced tumor grade (HR: 2.73; 95% CI: 1.39–5.34), and advanced tumor stage (HR: 2.71; 95% CI: 1.33–5.50) were associated with worse OS, whereas surgery (HR: 0.34; 95% CI: 0.20–0.60) and radiation therapy (HR: 0.55; 95% CI: 0.33–0.91), but not chemotherapy (HR: 1.16; 95% CI: 0.66–2.05), predicted improved OS. Conclusions SNAC is a rare malignancy with 5-year survival approximating 50%. Surgery and radiation therapy, but not chemotherapy, are associated with improved survival, and likely play a critical role in the interdisciplinary management of SNAC. [ABSTRACT FROM AUTHOR]

Objectives A persistent craniopharyngeal canal (CPC) is a rare embryologic remnant that presents as a well-corticated defect of the midline sphenoid body extending from the sellar floor to the nasopharynx. Our case series aims to describe three unique presentations of this congenital anomaly and their subsequent management. Design Retrospective review. Setting Tertiary academic medical center. Participants Patients who underwent endoscopic transnasal surgical repair of a CPC lesion. Main Outcome Measures Resolution of symptoms and surgical outcomes. Results A total of three patients were identified. The clinical presentation varied, however, all cases prompted further imaging which demonstrated a persistent CPC and associated pathologic lesion. The presentation of a persistent CPC with nasal obstruction and subsequent iatrogenic cerebrospinal fluid leak as in Case 1 demonstrates the importance of imaging in this work-up. Cases 2 and 3 in the series were representative of the larger subset of patients in the literature who present with the defect incidentally but still warrant surgical management. Nonetheless, a standard approach to diagnosis with preoperative imaging and subsequent transnasal endoscopic repair of the skull base defect was undertaken. Conclusion The persistent CPC is a rare congenital anomaly associated with diverse pathology and careful review of preoperative radiology is critical to the management. When warranted, subsequent surgical repair and reconstruction is associated with excellent postoperative outcomes. [ABSTRACT FROM AUTHOR]

Introduction Olfactory groove meningiomas (OGMs) are often associated with loss of smell following resection. Loss of smell has a measurable impact on quality of life. Smell preservation has been previously described in open approaches for early stage or unilateral OGMs. Evidence of smell preservation in endoscopic approaches is lacking. Design A multi-institutional retrospective review was performed on consecutive patients who underwent unilateral endoscopic endonasal resection of OGM. A gross total resection was achieved with preservation of the contralateral olfactory cleft and bulb. Olfactory function was assessed with a six-point olfactory symptom score and the Sniffin' Sticks 12-item smell identification test (SS-12). Contralateral olfactory bulb volume was measured on postoperative magnetic resonance imaging. Results Four patients (age 42.0 ± 7.5, 75% female) were assessed. Olfactory function was assessed at 21.8 ± 5.6 months following surgery. All patients reported some degree of smell preservation (75% described a slight/mild impairment in smell or better). Olfactory identification was preserved with an SS-12 score of 9 ± 1.4 (anosmia defined as ≤6). The olfactory bulb volume was calculated to be 47.4 ± 15.9 mm 3 (normal >40 mm 3). Conclusion Smell preservation is possible following unilateral endoscopic endonasal resection of carefully selected OGM. [ABSTRACT FROM AUTHOR]

Objectives Pituitary carcinoma is a rare entity with fewer than 200 total cases reported in the English literature. Analysis of the population-level data from the National Cancer Database (NCDB) affords the opportunity to study this poorly understood tumor type. Methods The NCDB was queried for site, histology, and metastasis codes corresponding to pituitary carcinoma. Statistical analyses were performed to determine factors associated with overall survival (OS). Results A total of 92 patients with pituitary carcinoma met inclusion criteria. The 1 and 5 years of OS for all patients was 93.3% (95% confidence interval [CI]: 88.2–98.6%) and 80.0% (95% CI: 71.6–89.4%), respectively. Patients with invasive primary tumor behavior had 1 and 5 years of OS of 69.2% (95% CI: 48.2–99.5%) and 52.7% (95% CI: 31.2–89.2%), respectively. Multivariate analysis demonstrated that compared with benign primary behavior, invasive behavior had increased all-cause mortality (hazard ratio [HR], 1,296, 95% CI: 15.1– > 2,000). Surgery without adjuvant radiation or chemotherapy was the most common therapy (48.9%), followed by no treatment (40.2%). Compared with surgery alone, no treatment had worse OS (HR, 11.83, 95% CI: 1.41–99.56). Increasing age and female sex were both associated with increased mortality. Conclusions The most common treatment for pituitary carcinoma is surgery alone followed by no surgery. Surgery alone has significantly better OS compared with no treatment. The efficacy of radiation, chemotherapy, and neurohormonal treatments needs to be examined with prospective studies. [ABSTRACT FROM AUTHOR]

Background An ectopic pituitary adenoma presenting as a clival or sphenoidmass is a rare clinical occurrence that may mislead the clinician and result in unnecessary interventions or potential medicolegal consequences. Here, we present one of the largest multi-institutional case series and review the literature with an emphasis on radiological findings and critical preoperative workup. Methods Retrospective chart review. Results Nine patients were identified with ectopic pituitary adenomas of the sphenoid or clivus. There were four females and five males. Median age was 60 years old (range, 36-73 years). The most common presenting symptom was headache (56%). Five (56%) patients presented with a mass arising fromthe clivus while four (44%) presented with a mass in the sphenoid. Six (67%) patients demonstrated biochemical evidence of hypersecretion on full endocrinology panel. All masses showed evidence of enhancement with gadolinium with a propensity for adjacent bone involvement. Lesions also had a predilection for growth toward the cavernous sinus, carotid artery, or sellar floor. Surgical intervention was performed in eight patients (89%). In eight patients (89%), tumors demonstrated immunoreactivity to prolactin. Conclusions Pituitary adenomas can rarely present as an isolated sphenoid or clival mass. Lesions displayed similar magnetic resonance imaging findings with an erosive growth pattern toward the sellar floor, cavernous sinus, or adjacent carotid artery. Patients with clival or parasellar lesions with comparable features should have a preoperative workup which includes prolactin level and alert the physician to consider an ectopic pituitary adenoma in the differential to prevent unnecessary surgery and potential complications.
