This study was performed to determine the quality of life and cost-effectiveness of therapeutic options for patients with locally recurrent rectal carcinoma, determined from the perspectives of patients and health care providers.
We reviewed the records of patients (N = 68) with locally recurrent rectal carcinoma evaluated from 1992 through 1995. We constructed a decision-analytic model incorporating outcomes, survival, and costs. Utilities were elicited from convenience samples of health care providers and patients using the standard gamble technique.
The median survival for patients undergoing surgical resection (n = 40) was 42 months, compared with 16.8 months for patients undergoing diagnostic or palliative surgery (n = 16) and 18.3 months for patients treated nonoperatively (n = 12; P < 0.005). The mean cost of treatment per patient was $19,283 for the nonoperative group, $45,647 for the diagnostic or palliative surgery group, and $70,878 for the surgical resection group. The diagnostic or palliative surgical strategy was dominated by the nonoperative strategy because the former had greater costs with fewer health benefits. The incremental cost-utility ratio of surgical resection compared with nonoperative management using health care provider utilities was $109,777 per quality-adjusted life year gained; it was reduced to $56,698 using per quality-adjusted life year using mean patient utilities.
Patients with recurrent rectal carcinoma view surgery and morbidity to be less severe than health care providers. Diagnostic or palliative surgery is expensive and affects quality-adjusted survival adversely compared with nonoperative therapy. Surgical resection may be a cost-effective use of resources, particularly when cost-effectiveness is calculated using patient preferences.
