178 Background: Recently, JCOG0502 trial have shown a comparable efficacy with chemoradiotherapy (CRT) and esophagectomy as standard treatment in patients with clinical stage (cStage) I esophageal squamous cell carcinoma (ESCC), showing the standard treatment option of CRT. However, there is few reports for comparison of clinical outcomes with these treatments in real-world. The aim of this study was to clarify the real-world outcomes in cStage I ESCC who performed with CRT or esophagectomy. Methods: This retrospective study included patients with clinical stage I ESCC who received thoracoscopic or open esophagectomy with three-field lymph node dissection or CRT mainly consisted of 5-fluorouracil and platinum with concurrent radiotherapy (50.4 Gy/28Fr or 60 Gy/30Fr) between 2009 and 2017 at National Cancer Center Hospital East. Survival outcomes were calculated using the Kaplan-Meier method, and the differences were evaluated using the log-rank test. Results: Among a total of 156 patients, 128 were male and median age was 68 years old. 120 and 36 patients underwent esophagectomy and CRT, respectively. ECOG performance status 0/1/2 were 138/12/6 patients. Tumor location was Ut/Mt/Lt in 16/87/53 patients. Clinical tumor depth (MM-SM1/SM2-SM3) were 33/123 patients. Patients’ characteristics were similar among treatment groups, except clinical tumor depth (SM2-3; 84.2% in esophagectomy group vs. 61.1% in CRT group, p = 0.005). All patients underwent radical surgery in esophagectomy group, while three patients (8.3%) in CRT group were received additional esophagectomy or endoscopic resection due to residual disease. With a median follow-up of 72 months, 5-year overall survival (OS) and progression-free survival rate were 81.5%/77.0% in esophagectomy group and 82.6/74.4% in CRT group (p = 0.89 and p = 0.48). In safety profile, grade 3 or higher stenosis was observed in 21.7% of esophagectomy group. There was no treatment-related death in both groups. In subgroup analysis for OS, elderly patients (75 years and older) tended to have better 5-year OS rate in CRT group (76.9% in esophagectomy group vs. 81.8% in CRT group), while younger patients ( < 75 years) showed comparable 5-year OS rate in both groups (82.4% in esophagectomy group vs. 82.9% in CRT group). Conclusions: Real-world data reproduced the results of clinical trial, supporting CRT as one of the standard treatment options in patients with cStage I ESCC.

67 Background: Chemoradiotherapy (CRT) of esophageal cancer has been proposed as an alternative to esophagectomy given the favourable survival rate and mild toxicity. However, no comparative study is reported between esophagectomy and CRT in stage I esophageal squamous cell carcinoma. Methods: A total of 54 patients treated by definitive CRT and 116 patients treated by esophagectomy at out institution between February 1995 and August 2008 were included in the analysis. Overall survival and recurrence rates were evaluated. Results: Of 170 patients who had clinical stage I esophageal squamous cell carcinoma and treated by definitive CRT or esophagectomy, 169 patients (99%) were completely followed up. CRT mainly consisted of two cycles of cisplatin and fluorouracil with concurrent radiotherapy of 60 Gy in 30 fractions. Median (range) observation period was 67 (10–171) months in SURG group and 30 (4–77) months in CRT group. In CRT group grade 3 or grade 4 hematological or non-hematological adverse effects were seen in 24 (44.4%) patients. 1-year and 3-year overall survival rates were 97.4% and 85.5% in the SURG group and 98.1% and 88.7% in the CRT group (P = 0.78). By using Cox proportional hazards modelling, overall survival was comparable between the 2 groups after adjusting for age, sex, and size of cancer. Hazard ratio of CRT for overall survival was 0.95 (95% CI: 0.37-2.47). The incidence or local recurrence including metachronous esophageal cancer was significantly higher in the CRT group than the SURG group (P < 0.0001). All recurrences were intramucosal carcinomas and all of them were cured after the salvage treatment mainly using endoscopy. Conclusions: Overall survival rate of CRT was comparable with esophagectomy despite high local recurrence rate. Local recurrent carcinoma is endoscopically treatable in all patients without influence on overall survival. CRT appears to be a reasonable alternative to esophagectomy in patients with stage I esophageal cancer. No significant financial relationships to disclose.
