Abstract 1444P

Background

In the United States, uniquely American risk factors have led to a rise in the incidence of esophageal adenocarcinoma. In contrast, Asians have generally shown a predominance of esophageal squamous cell carcinoma (SCC), and this has held among Asian-Americans. However, limited investigation of esophageal cancer within Asian-Americans has been conducted in recent years.

Methods

The Surveillance, Epidemiology, and End Results (SEER) Incidence Database was queried for patients from 2004-2020 classified as Asian/Pacific Islander and diagnosed with esophageal adenocarcinoma or squamous cell carcinoma. Descriptive statistics and multivariate models were utilized to compare incidence, cancer characteristics, treatment details, and survival in patients with esophageal adenocarcinoma and SCC.

Results

During this time, 2103 (73.71%) Asian-Americans presented with esophageal SCC compared to 750 (26.29%) with adenocarcinoma. Patients with SCC were diagnosed at a significantly older age (68.09 vs 66.10, p=

Conclusions

SCC remains the predominant histological subtype of esophageal cancer within Asian-Americans. Several factors may contribute to this, including BMI, immigration history, and retained cultural practices. However, adenocarcinoma should not be missed in this cohort. The later stage diagnosis of adenocarcinoma suggests that methods to improve early detection are necessary, and poorer survival of the SCC cohort indicates an opportunity to improve treatment paradigms.
