The use of chemoradiotherapy in oesophageal cancer

Abstract The results of treatment for oesophageal carcinoma remain poor and few patients are curable by surgery alone. The use of chemoradiotherapy (CRT) given as a definitive treatment or in combination with surgery may improve locoregional control and survival, when compared with radiotherapy or surgery alone. Using the keywords “chemoradiotherapy” and “radiochemotherapy”, a Medline-based literature review (1980–2001) was performed. Additional literature was obtained from original papers and published meeting abstracts. Two-year survival rates of 28–72% in squamous cell carcinoma and 14–29% in adenocarcinoma from definitive CRT were reported. This is comparable to results achievable by surgery alone. The use of preoperative CRT followed by surgery may further improve survival, but current data are insufficient to justify this approach within routine clinical practice. Acute treatment-related toxicity is increased with CRT. In selected patients with localised unresectable oesophageal cancer, definitive CRT is recommended. There are uncertainties about the role of routine surgery following CRT in patients with resectable disease. For the future, the pretreatment staging of patients needs to be improved and standardised, the optimal CRT regimen needs to be defined and the role of predictive markers for CRT response needs to be developed.
