OBJECTIVE: This review aimed at examining efficacy of interventional radiotherapy (brachytherapy-IRT) alone or combined with external beam radiotherapy (EBRT) in stage I esophageal cancer as exclusive treatment. MATERIALS AND METHODS: A systematic research using PubMed, Scopus, and Cochrane library was performed. ClinicalTrials.gov was searched for ongoing or recently completed trials, and PROSPERO was searched for ongoing or recently completed systematic reviews. We analyzed only clinical study as full-text publication, reporting on patients with stage I esophageal cancer treated with IRT alone or in combination with other treatments (e.g., EBRT). Conference paper, survey, letter, editorial, book chapter, and review were excluded. Patients who underwent previous surgery were excluded. Time restriction (1990-2018) was applied for years of the publication. RESULTS: Twelve studies have been selected. The number of evaluated patients was 514; the median age was 69 years. In the IRT group, the median: Local control (LC) was 77% (range 63%-100%), disease-free survival (DFS) was 68.4% (range 49%-86.3%), the overall survival (OS) was 60% (range 31%-84%), the cancer specific survival (CSS) was 80% (range 55-100%), and grade 3-4 toxicity range was 0%-26%. CONCLUSIONS: IRT alone or combined to EBRT is an effective and safe treatment option for patients with stage I esophageal cancer. Definitive radiation therapy could be an alternative to surgery in patients with superficial cancer.
