RESUMO
AIMS: Two randomised trials have shown that immediate completion lymphadenectomy for sentinel node positive melanoma provides no long-term survival benefit; compared with a follow up regime of intensive nodal surveillance. The aim of this study was to assess the cost and resource implications of introducing this regime for patients with sentinel node positive melanoma in a provincial New Zealand hospital. METHODS: Patients with cutaneous melanoma presenting to Northland District Health Board between 1 January 2012 and 31 December 2014 were identified. The financial and resource burden of standard treatment was assessed, including operative, outpatient and imaging interventions. Theoretical financial and resource costs of intensive nodal observation for a theoretically equivalent cohort were calculated. RESULTS: The cost of standard treatment was $7,147 per patient and the theoretical cost of nodal observation was $5,300 per patient. Standard treatment required more operating theatre time and inpatient treatment. Nodal observation required more outpatient appointments and imaging. CONCLUSIONS: The cost of nodal observation was lower than standard treatment than in our study. There is a shift in resource requirements from operating theatre and inpatient care to outpatient appointment and imaging. The overall resource impact is low and introduction of nodal observation appears achievable.
