Quality of life in patients with oesophageal cancer.

There is a growing interest in assessing quality of life in patients with oesophageal cancer because it provides detailed information of the patients' perception of the benefits or harms of treatment. Yet few studies have prospectively measured quality of life using validated appropriate instruments. There are now several questionnaires for patients with cancer, although these are not sufficiently sensitive to small but clinically important changes in quality of life. It is therefore recommended that a disease-specific module is used in conjunction with generic measures. The European Organisation into Research and Treatment of Cancer (EORTC) QLQ-OES24 is currently completing an international validation study. It is used with the EORTC QLQ-C30 core instrument and is designed for patients undergoing potentially curative treatment or palliation of malignant dysphagia. Studies that have assessed quality of life after oesophagectomy have generally found that survivors do regain their former health. Little is known about the effect of neoadjuvant chemoradiation on patients' quality of life. Following endoscopic palliation of dysphagia, quality of life can be maintained and improvement of swallowing is seen. A validated appropriate assessment of quality of life should be included in future palliative trials and in studies of new treatments which may marginally influence survival but cause significant side effects.
