A retrospective analysis was carried out of 291 cases of oesophageal cancer treated with definitive chemoradiotherapy (dCRT) at a single UK cancer centre between 1995 and 2009. Our protocol consisted of two cycles of neoadjuvant platinum-based chemotherapy followed by two further cycles given concurrently with 50Gy of external beam radiotherapy delivered in 25 fractions over 5 weeks.
Demographic, patient and outcome data were recorded prospectively through an electronic health record and retrospectively analysed, using appropriate statistical tools.
Data on 266 patients were available for analysis. The median age was 66.6 years, 53% were adenocarcinomas. dCRT was used instead of surgery because of age/co-morbidity in 44% and disease extent in 39%. Ninety-three per cent of patients completed treatment according to protocol. Grade 3 and 4 toxicities were seen in 42 and 7%, respectively. Median survival was 20.6 months; 2, 3 and 5 year survival rates were 43.6, 32.9 and 19.5%, respectively. Advanced disease was associated with a worse outcome. Shorter disease length was associated with a better median survival, but some patients with disease >10cm had long-term disease control. The effect of other patient- and disease-related factors was also analysed.
We present data showing that dCRT is well tolerated and should be considered as an alternative to surgery for all patients with locally advanced oesophageal cancer, not only those with co-morbidity. Furthermore, the benefits of dCRT are not confined to carcinomas with squamous histology.
对 1995 年至 2009 年期间在英国一家癌症中心接受根治性放化疗(dCRT)治疗的 291 例食管癌患者进行回顾性分析。我们的方案包括两个周期的新辅助铂类化疗,然后再进行两个周期的化疗,同时给予 50Gy 的外照射放疗,在 5 周内分 25 次进行。
通过电子病历系统前瞻性记录人口统计学、患者和结局数据,并进行回顾性分析,使用适当的统计工具。
266 例患者的数据可用于分析。中位年龄为 66.6 岁,53%为腺癌。由于年龄/合并症,44%的患者和疾病范围,39%的患者选择 dCRT 而不是手术。93%的患者按照方案完成了治疗。分别有 42%和 7%的患者出现 3 级和 4 级毒性。中位生存时间为 20.6 个月;2、3 和 5 年生存率分别为 43.6%、32.9%和 19.5%。晚期疾病与较差的预后相关。较短的疾病长度与较好的中位生存相关,但一些疾病长度>10cm 的患者有长期疾病控制。还分析了其他与患者和疾病相关的因素的影响。
我们提供的数据表明,dCRT 具有良好的耐受性,应考虑作为所有局部晚期食管癌患者的替代手术治疗方法,不仅限于合并症患者。此外,dCRT 的益处不仅限于鳞状组织学的癌。
