Difficulty swallowing in high-risk individuals demands prompt esophageal cancer evaluation

Two case-control studies encompassing 1,688 participants (593 esophageal squamous cell carcinoma cases and 1,095 controls) identified multiple risk factors that substantially elevate esophageal cancer risk. Gastric atrophy doubled OSCC risk (OR=2.01, 95% CI: 1.18–3.45), with synergistic effects when combined with poor dental health (OR=4.15, 95% CI: 2.04–8.42) or poor oral hygiene (OR=8.65, 95% CI: 3.65–20.46). Additional risk factors included opium use (OR=2.12), combined tobacco-opium use (OR=2.35), and ruminant contact (8-fold increased risk). These significant additive interactions (RERI=1.47 to 4.34) demonstrate that individuals with gastric atrophy, poor oral health, or substance use histories who develop difficulty swallowing face markedly elevated esophageal cancer probability, making timely clinical evaluation essential rather than dismissing the symptom.

Risk factors for esophageal squamous cell carcinoma

This case-control study identified multiple risk factors for ESCC including opium use (OR 2.12, 95% CI: 1.21–3.74), combined tobacco-opium use (OR 2.35, 95% CI: 1.50–3.67), gastric atrophy defined by pepsinogen I <55 μg/dl (OR 2.01, 95% CI: 1.18–3.45), and ruminant contact (8-fold increased risk) among 300 cases and 571 controls. Individuals with these risk factors experiencing esophageal symptoms warrant timely clinical evaluation.

In this case-control study with 293 OSCC cases and 524 matched controls from a high-risk region, gastric atrophy (PGI <55 μg/dL) doubled OSCC risk (OR=2.01, 95% CI: 1.18–3.45). When combined with poor dental health, risk increased to OR=4.15 (95% CI: 2.04–8.42), and when combined with poor oral hygiene, risk reached OR=8.65 (95% CI: 3.65–20.46). Both interactions showed statistically significant additive effects (RERI=1.47 and RERI=4.34, respectively), indicating that gastric atrophy combined with oral risk factors creates substantially elevated oesophageal cancer risk warranting vigilance for early symptoms.
