N2 - Purpose: To investigate the effect of prior chemotherapy on self-expanding metal stent (SEMS)-related complications in patients with locally advanced primary esophageal cancer. Materials and methods: Data from patients with locally advanced primary esophageal cancer who received SEMS placement with or without prior chemotherapy were retrospectively reviewed. Patients were grouped according to prior palliative therapy: group A (n = 41) had received SEMS only, and group B (n = 64) had received palliative chemotherapy prior to SEMS placement. Patients’ age, stricture length, tumor location, and dysphagia score prior to SEMS placement were evaluated. The overall patient cohort had a median follow-up period of 129 days (range 11–463). Outcomes after SEMS placement, including technical and clinical success rates, the occurrence of complications, and overall survival, were compared. Results: There were no significant differences between the two groups regarding patients’ age, stricture length, tumor location, and dysphagia score prior to SEMS placement. SEMS placement was technically successful in all patients, with no procedure-related complications reported. Clinical success was achieved in 95.1% of patients in group A and 96.8% of patients in group B. The duration of stent patency was significantly shorter in group B [162 days; 95% confidence interval (CI) 126.6–198.4 vs. group A (339 days; 95% CI 258.8–419.3], p = 0.001. No significant differences were seen between the two groups regarding dysphagia score improvement [group A (3.15 ± 0.57 to 1.17 ± 0.83; p < 0.001) and group B (3.17 ± 0.80 to 1.14 ± 0.79; p < 0.001); p = 0.66], complications [group A (10/41), and group B (24/64); p = 0.094], or overall survival [the median and mean overall survival periods were 105 (95% CI 30–180) and 132 days (95% CI 97–167), respectively, in group A, and 126 (95% CI 88–164) and 156 days (95% CI 132–180), respectively, in group B; p = 0.592]. Conclusion: Prior chemotherapy did not increase the risk of complications following SEMS placement in patients with locally advanced esophageal cancer. SEMS patency was significantly longer in patients who did not receive chemotherapy prior to SEMS placement. Level of Evidence: Level 4, Case Series.
