91

Results

ER and tumor length were independent predictive factors for LRFS. Our study suggested that performance of ER prior to CRT improved the local control in patients with c/p T1bN0M0 ESCC. In addition, most of the patients who experienced local recurrence were treated with salvage ER, which contributed to preserving the organs.

Baseline Characteristics

Patients with c/p T1bN0M0 ESCC treated with CRT in our institution from 2004 to 2017.

Participant flow

We retrospectively reviewed the medical charts of 91 patients with c/p T1bN0M0 ESCC treated with CRT in our institution from 2004 to 2017.

Adverse events

Leukopenia was one of the most common acute AEs, and the incidence of grade 3 or higher leukopenia was 14.3% in our study. Other grade 3 or higher acute AEs included esophagitis (3.3%) and fever (1.1%). Grade 3 or higher late AEs included pleural effusion (1.1%) and pericardial effusion (1.1%). Grade 3 or higher pneumonitis was found in 4.4% of patients, and they were all treated with corticosteroids. One patient died from grade 5 radiation pneumonitis (RP) in this study.

Outcome measures

We calculated the overall survival rate, disease specific survival rate, and local recurrence free survival rate.
