Demographic and socioeconomic factors in poorly differentiated Sertoli-Leydig cell tumors: A National Cancer Database analysis.

Abstract

e17568 Background: Poorly differentiated Sertoli-Leydig cell tumor (PD-SLCT) is a rare and aggressive type of ovarian cancer. This cancer has a 5-year cancer-specific survival rate of 43.9% with a chance of early relapse of approximately 2-3 years following initial diagnosis. Given the rarity of the cancer, potential risk factors could offer providers and patients more information about the epidemiology. The National Cancer Database (NCDB) was analyzed to study the demographic factors in patients diagnosed with PD-SLCT. Methods: Cases of PD-SLCT (N = 405) in the NCDB from 2004 – 2020 were determined via histology (ICD-O-3 code = 8631). A retrospective cohort analysis using demographic factors such as race, age, sex, insurance status, urban/rural, facility type, and Charleson-Deyo score were analyzed by descriptive statistics and incidence trends were interpreted in regression analysis. Results: A total of 405 patients with a diagnosis of PD-SLCT were identified in the database with a steady incidence of patients diagnosed per year (mean = 23.8 per year, R2 = 0.1). The average age of diagnosis was 41.7 years (SD = 20.1, range = 8 – 90 years). The majority of patients were non-Hispanic (82.5%) and White (69.4 %). More patients were in the top quartile of income earners (30.8.%) and were privately insured (56.8%) relative to those who were uninsured or insured by Medicare/Medicaid (43.2%). A greater percentage of patients with PD-SLCT were treated at a non-academic program (54.0%) compared to an academic/research program (46.0%). More patients lived in metropolitan counties with a population greater than 1 million (59.8%) versus less populated metropolitan communities or urban communities (40.2%). Most individuals (84.2%) had Charlson-Deyo comorbidity scores of 0. Conclusions: This novel study of the NCDB addresses a significant knowledge gap on patients with PD-SLCT, as it provides demographic insight into this rare type of tumor and the patients who are diagnosed with it. Most PD-SLCT patients tend to be in the premenopausal age, as previously described in literature. Most patients are White and non-Hispanic. This is the first time the socioeconomic factors of PD-SLCT patients have been described in the literature: patients are more likely to be in the top income quartile, live in densely populated metropolitan areas, and be treated in a non-academic program. Further research is needed to better understand the impact of these factors on the diagnosis of, treatments utilized, and overall survival of patients with PD-SLCT to ensure that all patients receive the best possible care, regardless of their background.
