Carcinoma of the esophagus is an aggressive and lethal malignancy with an increasing incidence worldwide. Incidence rates vary internationally, with the highest rates found in Southern and Eastern Africa and Eastern Asia, and the lowest in Western and Middle Africa and Central America. Patients with locally advanced disease face a poor prognosis, with 5-year survival rates ranging from 15%-34%. Recent clinical trials have evaluated different strategies for management of locoregional cancer; however, because of stage migration and changes in disease epidemiology, applying these trials to clinical practice has become a daunting task. We searched Medline and conference abstracts for randomized studies published in the last 3 decades. We restricted our search to articles published in English. Neoadjuvant chemoradiotherapy followed by surgical resection is an accepted standard of care in the United States. Esophagectomy remains an essential component of treatment and can lead to improved overall survival, especially when performed at high volume institutions. The role of adjuvant chemotherapy following curative resection is still unclear. External beam radiation therapy alone is considered palliative and is typically reserved for patients with a poor performance status.
食管癌是一种侵袭性和致命性的恶性肿瘤,其发病率在全球范围内呈上升趋势。国际上发病率存在差异,南部和东部非洲以及东亚的发病率最高,而西部和中部非洲以及中美洲的发病率最低。局部晚期疾病患者预后较差,5 年生存率为 15%-34%。最近的临床试验评估了局部区域癌症管理的不同策略;然而,由于分期迁移和疾病流行病学的变化,将这些试验应用于临床实践已成为一项艰巨的任务。我们在 Medline 和会议摘要中搜索了过去 30 年发表的随机研究。我们将搜索范围限制在英文发表的文章。新辅助放化疗后手术切除是美国公认的治疗标准。食管切除术仍然是治疗的重要组成部分,可以改善总体生存率,尤其是在高容量机构进行时。根治性切除术后辅助化疗的作用仍不清楚。单独外照射放疗被认为是姑息性的,通常仅用于身体状况不佳的患者。
