Abstract
Background
Surgery alone for locally advanced oesophageal cancer is associated with low cure rates. The benefits and risks of neoadjuvant chemoradiation for patients with oesophageal cancer were evaluated.
Methods
A systematic review of publications between 2000 and 2008 on neoadjuvant chemoradiation for oesophageal cancer was undertaken.
Results
Thirty-eight papers comprising 3640 patients met the inclusion criteria. Chemoradiation regimens varied widely with a predominance of 5-fluorouracil/cisplatin chemotherapy. Chemoradiation-related toxicity was reported in only ten studies and consisted mainly of neutropenia. The chemoradiation-related mortality rate was 2Β·3 per cent. The mean R0 resection rate and pathological complete response (pCR) rate were 88Β·4 and 25Β·8 per cent respectively. Postoperative morbidity was not uniformly reported. The in-hospital mortality rate after oesophagectomy following chemoradiation was 5Β·2 per cent. Five-year survival rates varied from 16 to 59 per cent in all patients and from 34 to 62 per cent in those with a pCR. Chemoradiation had a temporary negative effect on quality of life.
Conclusion
Neoadjuvant chemoradiation regimens for oesophageal cancer vary widely. Besides traditional outcome variables (such as survival), other parameters should be analysed (for example toxicity) to assess whether the risks of chemoradiation are sufficiently compensated for by the benefits.
