However, the safety of SEMSs in patients who received or who will be submitted to radiotherapy (RT) is uncertain. The study aimed to evaluate the impact of RT on adverse events (AEs) in patients with esophageal cancer with SEMSs. This is a retrospective study conducted at a tertiary cancer hospital from 2009 to 2018. We collected information regarding RT, the histological type of the tumor, the model of SEMSs and AEs after stent placement. Three hundred twenty-three patients with malignant stenosis or fistula were treated with SEMSs. The predominant histological type was squamous cell carcinoma (79.6%). A total of 282 partially covered and 41 fully covered SEMSs were inserted. Of the 323 patients, 182 did not received RT, 118 received RT before SEMS placement and 23 after. Comparing the group that received RT before stent insertion with the group that did not, the first one presented a higher frequency of severe pain (9\/118 7.6% vs. 3\/182 1.6%; P = 0.02). The group treated with RT after stent placement had a higher risk of global AEs (13\/23 56.5% vs. 63\/182 34.6%; P = 0.019), ingrowth\/overgrowth (6\/23 26.1% vs. 21\/182 11.5%; P = 0.045) and gastroesophageal reflux (2\/23 8.7% vs. 2\/182 1.1%; P = 0.034). Treatment with RT before stent placement in patients with inoperable esophageal neoplasm prolongs survival and is associated with an increased risk of severe chest pain. Treatment with RT of patients with an esophageal stent increases the frequency of minor, not life-threatening AEs.<\/jats:p>","DOI":"10.1093\/dote\/doad019","type":"journal-article","created":{"date-parts":[[2023,4,11]],"date-time":"2023-04-11T10:58:56Z","timestamp":1681210736000},"source":"Crossref","is-referenced-by-count":4,"title":["Impact
