Transhiatal vs extended transthoracic resection in oesophageal carcinoma: patients' utilities and treatment preferences

To assess patients' utilities for health state outcomes after transhiatal or transthoracic oesophagectomy for oesophageal cancer and to investigate the patients' treatment preferences for either procedure. The study group consisted of 48 patients who had undergone either transhiatal or transthoracic cesophagectomy. In an interview they were presented with eight possible health states following oesphagectomy. Visual Analogue Scale and standard gamble techniques were used to measure utilities Treatment preference for either transhiatal or trans-thoracic oesophagectomy was assessed. Highest scores were found for the patients' own current health state (Visual Analogue Scale: 0.77; standard gamble: 0.97). Lowest scores were elicited for the health state 'irresectable tumour' (Visual Analogue Scale: 0.13; standard gamble: 0.34). The Visual Analogue Scale method produced lower estimates (P <0.001) than the standard gamble method for all health states. Most patient characteristics and clinical factors did not correlate with the utilities, Ninety-five per cent of patients who underwent a transthoracic procedure and 52% of patients who underwent a transhiatal resection on would prefer the transthoracic treatment. No significant associations between any patient characteristics or clinical characteristics and treatment preference were found. Utilities after transhiatal or transthoracic cesophagectomy were robust because they generally did not vary by patient or clinical characteristics. Overall, most patients preferred the transthoracic procedure. (C) 2002 Cancer Research UK
