摘要: PURPOSE: To present a decision model that describes the clinical and economic outcomes of node-positive breast cancer with without postmastectomy radiation therapy (PMRT). METHODS: A Markov process was constructed to project natural history following mastectomy in premenopausal women. Biannual hazards local distant recurrence PMRT were derived from large meta-analysis adjuvant systemic trials for cancer. The addition reduced risk disease relapse by an odds ratio 0.69. Costs ($11,600) recurrent ($4,250 16,200/year) estimated available literature. projected number recurrences, relapse-free overall survival, costs 15 years, using discount rate 3%. Cost-effectiveness ratios calculated per incremental year life quality-adjusted gained. One- two-way sensitivity analyses performed determine results t...
