Abstract
Introduction
To retrospectively analyze the outcome of patients with esophageal cancer treated with neoadjuvant chemoradiation.
Methods
A total of 41 patients received neoadjuvant intent chemoradiation for esophageal cancer. Most patients had a locally advanced disease (T3/4: 82%, N+: 83%, M0: 100%) and squamous cell carcinoma (83%). All patients received concurrent chemotherapy with cisplatin/5-fluorouracil or mitomycin/5-fluorouracil. Median radiation dose was 50.4 Gy in the 25 patients who proceeded to surgery and 57.4 Gy in 16 patients who did not undergo surgery. FDG-PET/CT was used for treatment planning in 24 patients. A second FDG-PET/CT was available for response evaluation in 18 patients.
Results
Median follow-up was 16 months in all patients and 30 months in survivors. Radiotherapy was completed without interruptions >3 days in 90% of patients, and chemotherapy was carried out to >80% in 85% of patients. The 2‑year locoregional control rate was 60%, distant control rate 54% and overall survival rate 50%. Hematological toxicity grade 3/4 was observed in 34%/10% of patients and non-hematological toxicity grade 3/4 in 46%/2% of patients. Perioperative 30-day mortality was 4%. Subgroup analyses revealed that surgery significantly improved locoregional control (74% vs. 39%, p = 0.034), but not the 2‑year survival rate (54% vs. 43%, p = 0.246). In contrast, response based on FDG-PET/CT prior and after chemoradiation significantly predicted improved overall survival (2-year overall survival 61% vs. 40%, p = 0.048).
Conclusion
Outcomes of our cohort were comparable to other series using similar treatments. Surgery significantly improved locoregional control but not survival. Response based on FDG-PET/CT predicted survival and might be used for treatment stratification.
