Purpose : Insurance coverage was an important determinant of access to care and was on potential cause of disparities in lung cancer care outcomes. The aim of the study was to clarify the association between National Health Insurance Status (Health insurance vs Medicare) and survival of patients with non-small cell lung cancer (NSCLC) who underwent surgical treatment.
Methods : Among 544 patients who underwent surgical resection for primary NSCLC from January 1997 to July 2017, 116 patients (21.3%) were in the Medicare Group. Data were analyzed to identify the clinical manifestation and to compare the postoperative and oncologic outcomes between two groups.
Results : There was no significant different in distribution of pathologic stage (p=0.89). The rates of squamous cell carcinoma were significantly higher in the Medicare group (43.9% vs 30.9%, p=0.03). Minimally invasive surgical approach was performed more in the Health insurance group (67.3% vs 56.9%, p=0.04). In the Healthy insurance group, the median length of hospital stay was significantly shorter (8 days vs 11 days, p=0.01). Although postoperative mortality rates were not different between two groups (1.7% vs 2.1%, p=0.79), the incidence of postoperative complications was non-significantly higher in the Medicare group (35.1% vs 29.8%, P=0.29). The 5-year overall survival and freedom from recurrence were significantly lower in the Medicare group (63.9% vs 71.1%, p=0.045, 56.5% vs 62.3%, p=0.033, respectively). (Figure. 1)
Conclusion : Socioeconomic status based on National Health Insurance service could have a bad influence on overall survival in patients with surgical treated lung cancer.
