Epidemiology and Survival of Esophageal Cancer Patients in an American Cohort

Abstract

Objectives This study seeks to delineate trends in esophageal cancer patients in an American cohort and, in particular, examine the impact of race and histology on survival. Methods The association between over 50 variables between histology and race subgroups was evaluated. Survival was calculated using Kaplan-Meier curves and a multivariable Cox regression analysis (MVA) was performed. Results Poorer survival was noted in black vs. white (193 ± 65 days vs. 254 ± 39, 95% CI 205-295, p=0.07) and squamous cell cancer (SCC) vs. adenocarcinoma (AC) (233 ± 24 days vs. 303 ± 48, 95% CI 197-339, p=0.01) patients. In patients with resectable cancer, blacks had poorer survival than whites (253 ± 46 days vs. 538 ± 202, 95% CI 269-603, p=0.03), and SCC had poorer survival than AC (333 ± 58 vs. 638 ± 152 days, 95% CI 306-634, p=0.006). A higher percentage of white patients received surgery compared to black patients (36% vs. 8%, p=0.08). MVA revealed that only surgery was an independent predictor of mortality (p=0.001). Conclusion Black race and SCC were associated with poorer survival. On MVA, surgery was an independent predictor of mortality. Clinicians should be aggressive in offering potentially curative procedures to patients and eliminating socioeconomic barriers.
