Esophageal Stenting and Radiotherapy: A Multimodal Approach for the Palliation of Symptomatic Malignant Dysphagia

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.
