Abstract:
BACKGROUND:Lung cancer has the highest mortality in China. Different treatments are of great significance to the prognosis of patients. By comparing stage Ia non-small cell lung cancer (NSCLC) patients' survival rates for ablation and for sub-lobectomy, we studied the difference in the effects of the two treatments on patient prognosis.
METHODS:Using the Surveillance, Epidemiology, and End Results (SEER) database, we screened eligible patients with stage Ia NSCLC from January 2004 to December 2015. Then, 228 patients treated with ablation and 228 patients treated with sub-lobotomy were then selected based on propensity score matching. After stratification, matching, and adjustment the Kaplan-Meier analysis was performed to compare the overall survival rates of patients treated with the two procedures.
RESULTS:The Kaplan-Meier survival analysis showed that there is a significant difference between the ablation group and the sub-lobectomy group (P<0.05). In the univarlable analysis, the hazard ratio (HR) of sub-lobotomy group was 0.571 (95%CI: 0.455-0.717) compared with the ablation group. Patients treated with sub-lobectomy had a 0.571 times greater risk of adverse outcomes than those treated with ablation. In the multivariable analysis, the HR for sub-lobectomy group was 0.605 (95%CI: 0.477-0.766) compared with the ablation group. Patients treated with sub-lobectomy had a 0.605 time greater risk of adverse outcomes than those treated with ablation. The results suggested that the overall survival rate of patients with stage Ia NSCLC treated with sub-lobotomy was higher than that of patients treated with ablation.
CONCLUSIONS:This study suggests that there is a significant difference in overall survival of stage Ia NSCLC patients treated with ablation and with sub-lobotomy. Patients treated with sub-lobotomy for stage Ia NSCLC had higher overall survival than those treated with ablation.
