Abstract

Purpose: To review data for patients with stage T4 and/or M1 lymph node (lym) esophageal cancer who have been treated with definitive chemoradiotherapy since 2000 at a high-volume center in Japan. Patients and methods: We retrospectively reviewed all patients with T4 and/or M1 lym esophageal cancer who were treated by definitive chemoradiotherapy between 2000 and 2010. The eligibility criteria included (1) histopathologically proven esophageal cancer, (2) T4 and/or M1 lym (UICC 2002), (3) 20−79 years of age, (4) having undergone at least 1 cycle of concomitant chemotherapy, (5) having been irradiated with ≥50 Gy, and (6) having no other active malignant tumor during treatment. Toxicity was graded according to the Common Terminology Criteria for Adverse Events (CTCAE v3.0). Results: Data from 128 patients (70 with clinical stage III, 58 with clinical stage IV) were used for analysis in this study. The median observation period for survivors was 46.3 months. The 2- and 4-year overall survival rates were 32.8 and 24.4 %, respectively. The overall survival of patients without M1 lym was significantly better than that of patients with Ml lym (4-year, 32.6 vs 11.7 %, log-rank test; p = 0.04). Overall survival in more recent patients (2006–2010) did not show improvement when compared with past patients (2000–2005). Eight patients had late toxicities of grade ≥3. Conclusions: T4 patients without M1 lym showed a relatively good 4-year survival rate of approximately 33 %; however, the results did not show significant improvement after 2000.
