| Abstract | A best evidence topic in cardiothoracic surgery was written according to a structured protocol. The question addressed was whether trimodal therapy [neoadjuvant chemoradiotherapy (nCRT) in addition to surgery] improves survival in patients with resectable oesophageal cancer. Altogether 565 studies were identified using the below-mentioned search. Eleven represented the best evidence to answer the clinical question. The author, journal, date and country of publication, patient group, relevant outcomes and weaknesses are tabulated. All 11 studies were randomized controlled trials comparing surgery with trimodal therapy, 5 of which showed a survival advantage with combined treatment. The remaining six randomized controlled trials showed no difference between trimodal therapy and surgery alone. The 3-year survival for trimodal treatment varied between 19.3 and 58% compared with that for surgery alone which varied between 7 and 53%. Five of these studies compared trimodal therapy with surgery in terms of resection margins, three of which showed that trimodal therapy led to increased R0 resection rate. One study focused on the differences between adenocarcinoma and squamous cell tumours, and described equivalent effects of trimodal therapy in terms of survival. One randomized controlled trial showed improved survival in patients with complete regression of their tumour following induction treatment. Two studies suggested that induction treatment may lead to a higher operative mortality; however, an increase in disease-free survival was noted in one of the two studies. We conclude that trimodal therapy for resectable oesophageal cancer offers similar or even improved results compared with surgery alone in terms of survival. Furthermore, it is likely that there is an advantage for those patients who have a complete pathological response following induction treatment. |
