title: Impact of national health insurance on the survival rate of patients with osteosarcoma in Taiwan: review of 74 patients.
abstract: The 2-year survival rate for high-grade osteosarcoma was 46.9% before the introduction of National Health Insurance (NHI) in Taiwan on March 1, 1995, but increased to 73.8% after the implementation of NHI. The 5-year survival rate also increased, from 37.5% to 63.6%. Between May 1990 and May 2001, 74 patients with high-grade osteosarcoma were treated at our hospital. Median age was 17 years (range, 7-63 years). Inadequate surgical margins, poor histologic response to chemotherapy, advanced stage of disease, and incomplete treatment were strongly associated with poor prognosis. Before NHI, 10 patients had incomplete treatment, mainly because of unaffordable medical fees. After NHI, only three patients had incomplete treatment, due to personal reasons. Patient survival improved dramatically with advances in multiagent chemotherapy, but it was the NHI that enabled patients to complete expensive treatment courses, including preoperative neoadjuvant chemotherapy, limb-salvage surgery, and postoperative adjuvant chemotherapy. The NHI also improved the accessibility of medical care, with more patients presenting in the early stages of disease and, as a result, it not only improved survival rate but also increased the number of patients undergoing limb-salvage surgery. We concluded that the NHI significantly improved the survival rate for patients with osteosarcoma in Taiwan.
