Preoperative chemoradiotherapy vs chemotherapy for adenocarcinoma of the esophagogastric junction: a network meta-analysis : oncology
The prognosis of patients with adenocarcinoma of the esophagus and esophagogastric junction (AEG) is poor. From current evidence, it remains unclear to what extent preoperative chemoradiotherapy (CRT) or preoperative and/or perioperative chemotherapy achieve better outcomes than surgery alone.To ass...

| Summary: | The prognosis of patients with adenocarcinoma of the esophagus and esophagogastric junction (AEG) is poor. From current evidence, it remains unclear to what extent preoperative chemoradiotherapy (CRT) or preoperative and/or perioperative chemotherapy achieve better outcomes than surgery alone.To assess the association of preoperative CRT and preoperative and/or perioperative chemotherapy in patients with AEG with overall survival and other outcomes.Literature search in PubMed, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, ClinicalTrials.gov, and International Clinical Trials Registry Platform was performed from inception to April 21, 2023.Two blinded reviewers screened for randomized clinical trials comparing preoperative CRT plus surgery with preoperative and/or perioperative chemotherapy plus surgery, 1 intervention with surgery alone, or all 3 treatments. Only data from participants with AEG were included from trials that encompassed mixed histology or gastric cancer. Among 2768 initially identified studies, 17 (0.6%) met the selection criteria.The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines were followed for extracting data and assessing data quality by 2 independent extractors. A bayesian network meta-analysis was conducted using the 2-stage approach.Overall and disease-free survival, postoperative morbidity, and mortality.The analyses included 2549 patients (2206 [86.5%] male; mean [SD] age, 61.0 [9.4] years) from 17 trials (conducted from 1989-2016). Both preoperative CRT plus surgery (hazard ratio [HR], 0.75 [95% credible interval (CrI), 0.62-0.90]; 3-year difference, 105 deaths per 1000 patients) and preoperative and/or perioperative chemotherapy plus surgery (HR, 0.78 [95% CrI, 0.64-0.91]; 3-year difference, 90 deaths per 1000 patients) showed longer overall survival than surgery alone. Comparing the 2 modalities yielded similar overall survival (HR, 1.04 [95% CrI], 0.83-1.28]; 3-year difference, 15 deaths per 1000 patients fewer for CRT). Similarly, disease-free survival was longer for both modalities compared with surgery alone. Postoperative morbidity was more frequent after CRT plus surgery (odds ratio [OR], 2.94 [95% CrI, 1.01-8.59]) than surgery alone. Postoperative mortality was not significantly more frequent after CRT plus surgery than surgery alone (OR, 2.50 [95% CrI, 0.66-10.56]) or after chemotherapy plus surgery than CRT plus surgery (OR, 0.44 [95% CrI, 0.08-2.00]).In this meta-analysis of patients with AEG, both preoperative CRT and preoperative and/or perioperative chemotherapy were associated with longer survival without relevant differences between the 2 modalities. Thus, either of the 2 treatments may be recommended to patients. |
