Abstract

Background: Preoperative chemoradiotherapy (CRT) is a standard treatment for stage II/III esophageal cancer. Preoperative chemotherapy is also considered a standard treatment for stage II/III esophageal squamous cell carcinoma (ESCC) in patients who undergo radical lymph node dissection. We conducted a feasibility study of preoperative CRT with cisplatin plus 5-fluorouracil (CF) and elective lymph node irradiation followed by esophagectomy with radical lymph node dissection in patients with stage II/III ESCC. Methods: Patients with clinical stage II/III, excluding T4, ESCC (International Union Against Cancer TNM classification system, 6th edition) were eligible. Chemotherapy comprised two courses of CF infusion repeated after 4-weeks. Radiation therapy was concurrently administered to the primary tumor, metastatic lymph nodes, and regional lymph nodes at a dose of 41.4 Gy. After the completion of CRT, transthoracic esophagectomy with 2–3 fields lymphadenectomy was performed. The primary endpoint was the completion rate of protocol treatment with R0 resection. Results: Thirty-one eligible patients were enrolled. During CRT, the most common grade 3 or 4 toxicities were leukopenia (65%), neutropenia (65%), anemia (13%), thrombocytopenia (13%), febrile neutropenia (13%), anorexia (16%), esophagitis (16%) and hyponatremia (16%). Thirty patients (96.8%) underwent surgery. One patient received palliative chemotherapy because of appearance of lung metastasis during CRT. The completion rate of protocol treatment was 93.5% (29/31). There was one treatment-related death after surgery. Pathological complete response was achieved in 42% (13/30). Conclusion: Preoperative CRT with CF and elective lymph node irradiation showed an acceptable toxicity and promising activity especially in ESCC.
