BACKGROUND: Synchronous esophageal cancers can suppress the survival of patients with hypopharyngeal cancers. Esophageal screening with the image-enhanced endoscopy may identify more synchronous cancers while there is no evidence to support its benefit on survival. METHODS: A total of 281 and 320 patients were diagnosed with hypopharyngeal cancer before and after the policy of routine esophageal screening. Primary outcome measures were overall survival. RESULTS: Among those who received screening, 49 patients (49/180, 27.2%) had synchronous esophageal cancers; treatment planning was changed in 42 (23.3%). Before and after the policy, percentages of stage I-II synchronous cancers were 20% (3/15) and 53.1% (26/49), respectively. Adjunctive therapies for synchronous cancers have led to a better survival after the policy than before (P = 0.002). The Cox regression model quantified a survival benefit of 29% (95% CI: 11-43%) when adjusting for TNM stage of hypopharyngeal cancer. In post-policy period, the survival was better for those who chose screening than those who did not (HR: 0.57, 95% CI: 0.41-0.79). Among those without screening, there was no difference between the pre- and post-policy periods (HR: 0.96, 95% CI: 0.74-1.26). CONCLUSIONS: Patients with hypopharyngeal cancers may benefit from the esophageal screening with image-enhanced endoscopy through the better detection of early-stage synchronous cancers.
