Abstract
The effect of insurance status on overall survival (OS) of patients with cutaneous T-cell lymphoma (CTCL) is unclear. We identified 11,861 patients from the US National Cancer Data Base diagnosed with CTCL from 2004-2014, of which 6088 had private insurance, 756 had Medicaid, 4536 had Medicare, and 481 are uninsured. Privately insured patients were more likely to present at an early stage (p < .001). On multivariate Cox regression analysis, privately insured patients had significantly longer OS than patients with Medicaid (HR: 1.936, 95% CI: 1.680-2.230, p < .001), Medicare (HR: 1.342, 95% CI: 1.222-1.474, p < .001), or no insurance (HR 1.849, 95% CI: 1.539-2.222, p < .001). The survival advantage of privately insured patients persisted on relative survival and propensity score-matched analyses. In conclusion, privately insured patients were more likely to present at an early stage, and had longer OS than patients who were Medicaid-, Medicare-, or not insured.

Abstract
Primary cutaneous CD30+ T cell lymphoproliferative disorders (PCLPD), the second most common type of primary cutaneous T cell lymphomas, accounts for approximately 25-30% of cutaneous T-cell lymphoma cases. However, only small retrospective studies have been reported. We aimed to identify prognostic factors and evaluate the overall survival (OS) of patients with PCLPD stratified by ethnicity. We identified 1496 patients diagnosed with PCLPD between 2004 and 2014 in the US National Cancer Database. Chi-square test and anova were used to evaluate differences in demographic and disease characteristics, socioeconomic factors and treatments received. OS was evaluated with the log-rank test, Cox proportional hazard regression analysis, and propensity score matching. The study included 1267 Caucasians, 153 African Americans (AA), 43 Asians, and 33 of other/unknown ethnicity. Older age, higher Charlson-Deyo score, higher clinical stage and receipt of chemotherapy were predictors of shorter OS. Primary disease site on a lower extremity was associated with shorter OS, while a head and neck location was associated with longer OS. AA patients had shorter OS when compared to Caucasian patients on multivariate analysis. This ethnic disparity persisted on propensity-score matched analysis and after matching Caucasian and AA patients on demographic and disease characteristics, socioeconomic factors and treatments received, and age and gender-matched relative survival analyses.

Abstract
BACKGROUND The utilization and impact of the studies published using the National Cancer Database (NCDB) is currently unclear. In this study, we aim to characterize the published studies, and identify relatively unexplored areas for future investigations. METHODS A literature search was performed using PubMed in January 2017 to identify all papers published using NCDB data. Characteristics of the publications were extracted. Citation frequencies were obtained through the Web of Science. RESULTS Three hundred 2 articles written by 230 first authors met the inclusion criteria. The number of publications grew exponentially since 2013, with 108 articles published in 2016. Articles were published in 86 journals. The majority of the published papers focused on digestive system cancer, while bone and joints, eye and orbit, myeloma, mesothelioma, and Kaposi Sarcoma were never studied. Thirteen institutions in the United States were associated with more than 5 publications. The papers have been cited for a total of 9858 times since the publication of the first paper in 1992. Frequently appearing keywords congregated into 3 clusters: "demographics," "treatments and survival," and "statistical analysis method." Even though the main focuses of the articles captured a extremely wide range, they can be classified into 2 main categories: survival analysis and characterization. Other focuses include database(s) analysis and/or comparison, and hospital reporting. CONCLUSION The surging interest in the use of NCDB is accompanied by unequal utilization of resources by individuals and institutions. Certain areas were relatively understudied and should be further explored.
