RESUMO
OBJECTIVE: To evaluate the cost-effectiveness of samarium [153Sm-EDTMP] (Quadramet) compared to conventional therapy in the treatment of pain in patients with prostate cancer and bone metastases. METHOD: A decision tree model for the treatment of bone pain due to metastases was adapted to the Spanish context. The model represents the standard treatment patterns in Spain for the study population. The time-course of the model is 4 months and it computes an estimate for the cost of pain control per patient. The effectiveness data for the model derive from a randomised trial. The current treatment patterns have been established according to the consensus opinions of a group of medical experts. RESULTS: The cost of pain control per patient is euro 12,515.39 for conventional therapy and euro 5,595.52 for samarium-153 (Quadramet) therapy. The incremental cost-effectiveness analysis shows that samarium-153 (Quadramet) is a dominant therapy. It presents lower costs and higher efficacy than the conventional strategy. The sensitivity analyses showed these results to be robust. CONCLUSION: Samarium-153 (Quadramet) is cost-effective in treating pain in patients with prostate cancer and bone metastases.

Objetivo. Realizar un análisis coste-efectividad de samario [153Sm-EDTMP] (Quadramet®) respecto a la terapia convencional, para el tratamiento del dolor causado por metástasis óseas en pacientes con cáncer de próstata. Metodología. Se ha adaptado un modelo de árbol de decisión, que representa el tratamiento del dolor óseo metastásico, al contexto español. El modelo muestra las opciones terapéuticas habituales en el contexto sanitario español para la población del estudio. El horizonte temporal del modelo es de 4 meses y calcula el cociente coste-efectividad por paciente controlado. Los datos de eficacia del modelo provienen de un ensayo clínico aleatorizado. Las pautas de tratamiento habituales en España han sido indicadas por varios especialistas médicos. Resultados. El coste por paciente controlado para la terapia convencional es de 12.515,39 y para la terapia con samario-153 (Quadramet®) es de 5.595,52 . El análisis coste-efectividad incremental muestra que samario-153 (Quadramet®) es una terapia dominante, es decir, que presenta una mayor eficacia y un menor coste que la terapia convencional. Los resultados obtenidos han demostrado ser robustos en un extenso análisis de sensibilidad. Conclusiones. La terapia con samario-153 (Quadramet®) es eficiente en el tratamiento del dolor de pacientes con cáncer de próstata y metástasis óseas
