Background: Esophageal stents provide immediate palliation of malignant dysphagia; however, radiotherapy (RT) is a superior long-term option. We review the outcomes of combined esophageal stenting and RT for patients with malignant dysphagia.
Methods: We retrospectively reviewed patients with esophageal stents placed for palliation of malignant dysphagia from esophageal stricture, esophageal extrinsic compression, or malignant tracheoesophageal fistula (TEF). We excluded patients with radiation-induced TEF in the absence of tumor. We analyzed and compared outcomes between patients with no RT, RT before stent placement, and RT after stent placement.
Results: We placed stents in 45 patients for esophageal stricture from esophageal cancer (n = 30; 66.7 %), malignant TEF (n = 8; 17.7 %), and esophageal compression from airway, mediastinal, or metastatic malignancies (n = 7; 15.6 %). Twenty patients (44.4 %) had no RT; 25 patients had RT before stent placement (n = 16; 35.6 %), RT after stent placement (n = 8; 17.8 %), or both (n = 1; 2.2 %). Median follow-up was 30 days. Complications requiring stent revision were similar with or without RT. Subjective symptom relief was achieved in 68.9 % of all patients, with no differences noted between groups (p = 0.99). The 30-day mortality was 15.6 %. Patients with RT after stent placement had a longer median survival compared to those without RT (98 vs. 38 days).
Conclusions: Esophageal stent placement with RT is a safe approach for malignant dysphagia.
