Limited resection for carcinoma of the upper thoracic oesophagus is not a realistic option

Aims: Due to its anatomical position, carcinoma of the proximal oesophagus results in early invasion of adjoining structures, often precluding (radica l) resection. We performed a retrospective study to compare the potentially curative and palliative treatment results in patients with proximal (i.e. at or above the carina) vs distal oesophageal carcinoma. Methods: Over a 3-year period 30 patients with proximal and 145 patients wi th distal oesophageal cancer underwent surgery. Results: Microscopically radical resection was achieved in 11/30 patients ( 43%) with a proximal tumour and in 96/145 patients (66%) with a distal tumo ur (P = 0.007). Three-year survival was 13.8% vs 44.3% respectively; locali zation was an independent prognostic factor. Recurrent upper aero-digestive tract symptoms developed in 38% of the patients with a proximal tumour and in 19% of the patients with distal carcinoma (P<0.05). Discussion: Carcinoma of the proximal oesophagus has a worse prognosis than more distal carcinomas. Definite cure is exceptional; many patients are in effectively palliated. In patients with proximal oesophageal carcinoma surg ery should not be performed outside clinical trials testing multimodality t reatment. (C) 2000 Harcourt Publishers Ltd.
