Abstract

Background: The aim of this review was to compare the available treatments of esophageal cancer, in terms of pulmonary, cardiovascular complications, anastomotic leakage, and esophagitis after treatment in patients with esophageal squamous cell carcinoma (SCC). Methods: Medline, Web of Science, Scopus, the Cochrane Library and Embase were searched. The randomized controlled trials (RCT) that had compared the treatment -related complications of treatments for esophageal SCC were included. We included 39 randomized control trials in a network meta-analysis. The Chi2-test was used to assess of heterogeneity. The loop-specific and design-by-treatment interaction methods were used for assessment of consistency assumption. The risk ratio with 95% confidence interval (CI) was used to report the effect-sizes in the network meta-analysis. Results: The pulmonary complication, cardiac complication, anastomotic leakage, and esophagitis were reported in 31, 11, 17, and 15 RCTs respectively. Video-assisted thoracoscopy + laparoscopy (VATS) was rank as the first and second treatment in terms of lower risk for pulmonary complication and anastomotic leakage. There was no statistically significant difference between treatments in terms of lower risk of cardiovascular complications. However, Surgery + Cisplatin + Fluorouracil (SCF) was ranked as better treatment. 3-dimensional conformal radiotherapy + Docetaxel + Cisplatin (3DCRTDC) was the best treatment in terms of lower risk for esophagitis. Conclusion: According to the results of this study, it seems the risk of pulmonary, cardiovascular, anastomotic leakage and esophagitis complications for VATS, SCF, surgery + radiotherapy (SRT), and 3DCRTDC was lower than other treatments respectively in the networks. © 2020 Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Ireland
