BACKGROUND/AIM: To validate the effect of treatment intensification on survival in esophageal squamous cell carcinoma (ESCC) patients undergoing definitive concurrent chemoradiotherapy (dCCRT).
We reviewed the medical records of 73 ESCC patients who underwent dCCRT between 2006 and 2017 in 3 institutions.
The median follow-up time was 13.3 months. The median overall survival (OS) and locoregional recurrence-free survival (LRFS) were 13.3 and 11.2 months, respectively. The median radiotherapy dose was 55.8 Gy, and the median biologically effective dose (BED) was 65.8 Gy. Chemotherapy was given in all patients during dCCRT, and adjuvant chemotherapy was administered in 56 patients (76.7%). Adjuvant chemotherapy improved OS (3-year, 24.2% vs. 11.8%, p=0.004). Higher BED ≥70 Gy improved LRFS (3-year, 41.7% vs. 23.6%, p=0.035).
The addition of chemotherapy after dCCRT improves OS. A higher radiotherapy dose improved LRFS, but not OS. Adjuvant chemotherapy should be considered after dCCRT for better outcomes.
背景/目的：验证强化治疗对接受根治性同期放化疗（dCCRT）的食管鳞癌（ESCC）患者生存的影响。
我们回顾了 3 家机构在 2006 年至 2017 年间接受 dCCRT 的 73 例 ESCC 患者的病历。
中位随访时间为 13.3 个月。中位总生存期（OS）和局部区域无复发生存期（LRFS）分别为 13.3 个月和 11.2 个月。中位放疗剂量为 55.8 Gy，中位生物有效剂量（BED）为 65.8 Gy。所有患者在 dCCRT 期间均接受化疗，56 例（76.7%）患者接受辅助化疗。辅助化疗改善了 OS（3 年，24.2% vs. 11.8%，p=0.004）。较高的 BED≥70 Gy 改善了 LRFS（3 年，41.7% vs. 23.6%，p=0.035）。
dCCRT 后添加化疗可提高 OS。较高的放疗剂量改善了 LRFS，但对 OS 没有影响。dCCRT 后应考虑辅助化疗以获得更好的疗效。
