PURPOSE: To assess the impact of clinical and nutritional factors on overall survival (OS) and time to disease progression of oesophageal cancer patients treated with neoadjuvant chemoradiotherapy (CRT) and surgery. METHODS: We retrospectively studied and analysed several clinical and nutritional factors, such as performance status, weight changes before and during CRT, dysphagia, nutritional support, and serum albumin to see whether they exerted any impact on OS and time to disease progression. RESULTS: In 107 patients the average weight loss was 9.7% from the onset of signs of disease to the beginning of therapy and 3% during CRT. In univariate analysis, significant unfavorable impact on survival was proved for low performance status, severe dysphagia, need for nasogastric tube insertion, above-average weight loss before treatment, weight loss >5% during CRT, and serum albumin ≤ 35 g/l before or after CRT. Patients supported by oral nutritional supplements (ONS) had higher probability to attain full dosage of CRT and radical resection than did those obtaining dietary advice alone. In multivariate analysis, serum albumin level, nasogastric (NG) tube insertion and pretreatment body weight loss were independent prognostic factors for OS, while serum albumin level after CRT and NG tube insertion were prognosticators for time to progression. CONCLUSION: Serum albumin level can serve as a useful prognostic factor for the outcome of patients with oesophageal cancer treated with neoadjuvant CRT and surgery. Appropriate nutritional support of these patients increased the probability of attaining full dosage of CRT and radical disease resection.
