AIM: to appraise the role of volumetric-modulated arc therapy (VMAT) in the neoadjuvant chemoradiotherapy management of advanced medium and distal oesophageal cancer in terms of toxicity and response to treatment. PATIENTS AND METHODS: Thirty patients were treated according to the neoadjuvant chemoradiation followed by surgery versus surgery-alone trial scheme with VMAT radiation therapy. Patients presented mainly T3-T4 stage (80%) and N1-2 (96.6%) disease. The chemotherapy scheme consisted of 3-5 cycles, while a radiotherapy course of 41.4 Gy in 23 fractions was administered to all patients. RESULTS: The median age of patients was 65 years, and there was a predominance of males (80%), smokers or ex-smokers (90%) and modest alcohol habit (80% negative). Primary tumor localisation was in the medium and distal third of the oesophagus in 57% of the cases, the rest being in the gastro-oesophageal junction. Modest toxicity profiles were observed, with limited incidence of grade 2-3 events. Partial or complete response was observed in more than 90% of the cases (radiological/metabolic) and was confirmed after surgical intervention (67% partial or complete and 27% stable response). Tumor down-staging was recorded in 67% of patients and nodal down-staging in 50%. CONCLUSION: VMAT was applied in the context of neoadjuvant chemoradiotherapy for the treatment of medium and distal oesophageal carcinoma with satisfactory results in terms of tolerance and toxicity.
