Objective To examine factors associated with hospital safety net burden and its impact on survival for patients with sinonasal squamous cell carcinoma (SNSCC). Study Design Retrospective database study. Setting National Cancer Database from 2004 to 2016. Methods SNSCC cases were identified in the National Cancer Database. Hospital safety net burden was defined by percentage of uninsured/Medicaid patients treated, namely ≤25% for low-burden hospitals, 26% to 75% for medium-burden hospitals, and >75% for high-burden hospitals (HBHs). Univariate and multivariate analyses were used to investigate patient demographics, clinical characteristics, and overall survival. Results An overall 6556 SNSCC cases were identified, with 1807 (27.6%) patients treated at low-burden hospitals, 3314 (50.5%) at medium-burden hospitals, and 1435 (21.9%) at HBHs. On multivariate analysis, Black race (odds ratio [OR], 1.39; 95% CI, 1.028-1.868), maxillary sinus primary site (OR, 1.31; 95% CI, 1.036-1.643), treatment at an academic/research program (OR, 20.63; 95% CI, 8.868-47.980), and treatment at a higher-volume facility ( P < .001) resulted in increased odds of being treated at HBHs. Patients with grade III/IV tumor (OR, 0.70; 95% CI, 0.513-0.949), higher income ( P < .05), or treatment modalities other than surgery alone ( P < .05) had lower odds. Survival analysis showed that hospital safety net burden status was not significantly associated with overall survival (log-rank P = .727). Conclusion In patients with SNSCC, certain clinicopathologic factors, including Black race, lower income, treatment at an academic/research program, and treatment at facilities in the West region, were associated with treatment at HBHs. Hospital safety net burden status was not associated with differences in overall survival. Level of evidence 4.
Objectives To investigate the impact of facility volume on Patient Safety Indicator (PSI) events following transsphenoidal pituitary surgery (TSPS). Study Design Retrospective database review. Setting National Inpatient Sample database (2003-2011). Methods The National Inpatient Sample was queried for TSPS cases from 2003 to 2011. Facility volume was defined by tertile of average annual number of TSPS procedures performed. PSIs, based on in-hospital complications identified by the Agency of Healthcare Research and Quality, and poor outcomes, such as mortality and tracheostomy, were analyzed. Results An overall 16,039 cases were included: 804 had ≥1 PSI and 15,235 had none. A greater proportion of male to female (5.8% vs 4.3%) and Black to White (7.0% vs 4.5%) patients experienced PSIs. There was an increased likelihood of poor outcome (odds ratio [OR], 3.1 [95% CI, 2.5-3.7]; P < .001) and mortality (OR, 30.1 [95% CI, 18.5-48.8]; P < .001) with a PSI. The incidence rates of PSIs at low-, intermediate-, and high-volume facilities were 5.7%, 5.1%, and 4.2%, respectively. Odds of poor outcome with PSIs were greater at low-volume facilities (OR, 3.3 [95% CI, 2.4-4.4]; P < .001) vs intermediate (OR, 3.1 [95% CI, 2.1-4.2]; P < .001) and high (OR, 2.5 [95% CI, 1.7-3.8]; P < .001). Odds of mortality with PSIs were greater at high-volume facilities (OR, 43.0 [95% CI, 14.3-129.4]; P < .001) vs intermediate (OR, 40.0 [95% CI, 18.5-86.4]; P < .001) and low (OR, 17.3 [95% CI, 8.0-37.7]; P < .001). Conclusion PSIs were associated with a higher likelihood of poor outcome and mortality following TSPS. Patients who experienced PSIs had a lower risk of poor outcome but increased mortality at higher-volume facilities.
Background While extramedullary plasmacytomas are infrequently encountered plasma cell malignancies, most cases occur in the head and neck, with a predilection for the sinonasal cavity. Due to the rarity of this disease, the majority of studies on sinonasal extramedullary plasmacytoma (SN-EMP) are case reports or small retrospective case series. Objective To investigate the impact of patient, disease, and treatment factors on the survival of patients with SN-EMP. Methods The National Cancer Database was queried for all patients with SN-EMP between 2004–2016 (N = 381 cases). Univariate and multivariate analyses were used to examine patient demographics, tumor characteristics, and survival. Results The majority of SN-EMP patients were over 60 years old (57.0%), male (69.8%), and white (86.2%). The most common treatment modality was radiotherapy alone (38.6%), followed by surgery plus radiotherapy (37.8%). Five-year overall survival was 74.0% and median survival was 9.1 years. Accounting for patient demographics and tumor characteristics in a multivariate model, the following groups had worse prognosis: 60 and older (HR 1.99, p = 0.031) and frontal sinus primary site (HR 11.56, p = 0.001). Patients who received no treatment (HR 3.89, p = 0.013), chemotherapy alone (HR 5.57, p = 0.008) or radiotherapy plus chemotherapy (HR 2.82, p = 0.005) had significantly lower survival than patients who received radiotherapy alone. Patients who received surgery with radiotherapy (HR 0.57, p = 0.039) had significantly higher survival than patients who received radiotherapy alone. Conclusion In patients with SN-EMP five-year overall survival was found to be 74.0% with decreased survival associated with a frontal sinus primary site and being aged 60 or older. Patients receiving no treatment, chemotherapy alone, or radiotherapy with chemotherapy was associated with lower survival. Receiving surgery plus radiotherapy was associated with the highest five-year overall survival.
ObjectiveTo investigate the survival benefit of elective neck dissection (END) over neck observation in cT1‐4 N0M0 head and neck verrucous carcinoma (HNVC).Study DesignRetrospective cohort study.SettingThe 2006 to 2017 National Cancer Database.MethodsPatients with surgically resected cT1‐4 N0M0 HNVC were selected. Linear, binary logistic, Kaplan‐Meier, and Cox proportional hazards regression models were utilized.ResultsOf 1015 patients satisfying inclusion criteria, 223 (22.0%) underwent END. The majority of patients were male (55.4%) and white (91.0%) with disease of the oral cavity (67.6%) classified as low grade (90.0%) and cT1‐2 (81.8%). The minority of ENDs (4.0%) detected occult nodal metastases. The rate of END increased from 2006 to 2017 for both cT1‐2 (16.3% vs 22.0%, p = .126, R2 = 0.405) and cT3‐4 (41.7% vs 70.0%, p = .424, R2 = 0.232) disease but these trends were not statistically significant. Independent predictors of undergoing END included treatment at an academic facility (adjusted odds ratio [aOR]: 1.75, 95% confidence interval [CI]: 1.19‐2.55), cT3‐4 disease (aOR: 3.31, 95% CI: 2.16‐5.07), and tumor diameter (aOR: 1.09, 95% CI: 1.01‐1.19) (p < 0.05). The 5‐year overall survival (OS) of patients treated with and without END was 71.3% and 70.6%, respectively (p = .661). END did not significantly reduce the 5‐year hazard of death (adjusted hazard ratio: 1.25, 95% CI: 0.91‐1.71, p = .172). END did not significantly improve 5‐year OS in univariate and multivariate analyses stratified by several patient, facility, tumor, and treatment characteristics.ConclusionEND does not confer an appreciable survival benefit in HNVC, even after stratifying univariate and multivariate analyses by several patient, facility, tumor, and treatment characteristics.Level of EvidenceLevel 4.
