Dysphagia prevalence and associated survival differences in older patients with lung cancer: A SEER-Medicare population-based study.

ABSTRACT:

Introduction

The impact of dysphagia in persons with lung cancer is unknown. The objective of this study is to measure the prevalence and survival differences associated with dysphagia in older adults with lung cancer.

Materials and methods

Linked SEER cancer registries - Medicare data, 1991-2009 was utilized to identify 201,674 persons with lung cancer. Most were male (53%), had regional or distant disease (74%), and were aged <80 years (82%). The pre-existing prevalence of dysphagia was identified using claims codes before the lung cancer diagnosis. Survival was analyzed using Kaplan Meier curves and Cox proportional hazard models.

Results

8517 (4%) had dysphagia prior to their lung cancer diagnoses. Younger age, worse disease stage, more comorbidities, and hospital
