A best evidence topic in cardiothoracic surgery was written according to a structured protocol. The question addressed was whether neoadjuvant chemotherapy improves survival in patients with resectable oesophageal cancer. Altogether 685 papers were identified using the below mentioned search. Nine represented the best evidence to answer the clinical question. The author, journal, date and country of publication, patient group, relevant outcomes and weaknesses were tabulated. We conclude that combining neoadjuvant chemotherapy with surgery for resectable thoracic oesophageal cancer has theoretical appeal and may offer a modest survival advantage compared to surgery alone. The most recent meta-analysis and the largest randomised trial of 804 patients demonstrated an absolute survival advantage of around 7-9% at two years which just reached statistical significance. Benefit was less clear for squamous cell carcinoma than adenocarcinoma and the second largest randomised trial did not demonstrate a significant benefit.
一篇心胸外科的最佳证据主题文章是根据结构化方案撰写的。所探讨的问题是新辅助化疗是否能提高可切除食管癌患者的生存率。通过下述检索共识别出685篇论文。其中9篇代表了回答该临床问题的最佳证据。对作者、期刊、出版日期和国家、患者群体、相关结果及不足之处进行了列表整理。我们得出结论,对于可切除的胸段食管癌,新辅助化疗联合手术具有理论上的优势,与单纯手术相比可能带来适度的生存获益。最近的荟萃分析以及纳入804例患者的最大规模随机试验表明,两年时绝对生存获益约为7 - 9%,刚刚达到统计学显著性。鳞状细胞癌的获益不如腺癌明确,第二大规模的随机试验未显示出显著获益。
