Purpose : The purpose was to describe trends of surgery for lung cancer patients in South Korea from 2005 to 2016, and to analyze related informatics, patterns of hospital selection, and its efficacy.
Methods : We screened 212,554 patients with code C34 (lung cancer) in the Korean National Health Insurance (KNHI) database from 2005 to 2016. Patients who underwent surgery without adjuvant treatment were selcted. Descriptive statistics and p-for-trend were used to analyze surgical patterns according to gender, ages, residence, and income. Survival analysis for hospital selection using log-rank test and multivariate analysis using Cox regression were performed.
Results : A total of 49,021 patients were selected. Surgery increased especially in patients of female, city and middle-income. Of them, lobectomy was prominent in female, low-income, and patients over 75 years. Except for metropolitan, there was a tendency preferring hospitals out of residence, which led to better survival (all P < 0.000). However, Patients of low-income and over 75 years were not able to keep up with this trend (P = 0.838 and 0.556). Hospital out of residence, living in metropolitan, high-income, and lobectomy (all P < 0.000) were better prognostic factors.
Conclusion : Lung cancer surgery in South Korea is increasing in all classes, especially lobectomy in vulnerable groups. It will change the current distribution of the surgery. The trend preferring hospitals out of their residence had gradually increased, which was reasonable in terms of survival. However, this trend requires improvement as it can cause regional imbalances in medical resources and decrease the clinical outcomes of vulnerable groups.
