RESUMEN
PURPOSE: To investigate the risk of second primary neoplasms (SPNs) after primary sebaceous carcinoma of the eyelid (SCE). METHODS: Data on patients diagnosed with primary SCE as their first malignancy were extracted from the Surveillance, Epidemiology, and End Results database from 2000 to 2016. Observed-to-expected ratios of SPNs were calculated to estimate standardized incidence ratios (SIRs). Patients were compared with a reference population (RP) matched for age, gender, and race. RESULTS: Five hundred fifty-nine patients with primary SCE were identified, 16% of whom developed SPNs. SCE patients displayed a 61% increased risk of developing SPNs compared with the RP (p < 0.001). Overall, the risk of SPNs of the lungs (SIR = 1.82; p < 0.05), pancreas (SIR = 2.94; p < 0.05), salivary glands (SIR = 41.65; p < 0.001), and skin (SIR = 8.33; p < 0.05) was elevated. Only non-Hispanic Whites were at an increased risk (SIR = 1.51; p < 0.05). Patients 40-54 years old at the time of diagnosis were at the highest risk of developing SPNs compared with the RP (SIR = 3.15; p < 0.05). Women with SCE experienced an increased risk of breast cancer (SIR = 3.6; p < 0.05) and chronic lymphocytic leukemia (SIR = 8.8; p < 0.01). CONCLUSION: SCE patients are more likely to develop SPNs of the lungs, pancreas, salivary gland, and skin than the RP. Forty to fifty-four years old Caucasian patients are at the highest risk. Women are at an increased risk of developing breast malignancies and chronic lymphocytic leukemia. Clinicians should be cognizant of these risks when managing SCE patients.

OBJECTIVES: Esthesioneuroblastoma (ENB) is a rare sinonasal malignancy with little known regarding how regional and socioeconomic differences in the United States alter disease survival. The aim of this study is to explore the geographic difference in clinical features, socioeconomic factors, and survival outcomes of ENB patients. METHODS: ENB cases were extracted from the Surveillance, Epidemiology, and End Results registry from 1975-2016. Patient data were stratified based on geographical location and comparative analyses of socioeconomic features, disease characteristics, and survival patterns were performed. Kaplan-Meier regression analyses were used to estimate disease-specific survival (DSS). RESULTS: A total of 987 patients were identified: 56.4% West, 14.0% South, 12.7% Midwest, and 16.6% East. The West had the highest proportion of patients with Medicaid coverage (P < .001), stage A malignancy (P < .001), and treated with surgery and adjuvant radiotherapy (P < .001). The South had the highest proportion of patients who were Black (P < .001), uninsured (P < .001), and resided in rural areas (P < .001). Five-year DSS patterns were 81.0% (West), 79.8% (East), 67.4% (Midwest), and 72.7% (South) [P = .018]. Ten-year DSS outcomes were 74.0% (West), 73.7% (East), 60.9% (Midwest), and 63.6% (South) [P = .017]. CONCLUSION: In ENB patients, survival disparity exists in the United States based on geographical region. Patients from the West and East exhibit higher survival than those from the South and Midwest. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:E2162-E2168, 2021.
