Abstract:
Objective To clarify the significance of chest radiotherapy in the treatment of oligometastatic stage Ⅳ non-small cell lung cancer ( NSCLC ) and to explore the optimal time of interventional therapy during chest radiotherapy. Methods A total of 192 patients with oligometastatic stage Ⅳ NSCLC admitted to Shanxi Provincial Cancer Hospital from 2008 to 2014 were randomly and evenly divided into the chemotherapy alone, radiotherapy+ early intervention, radiotherapy+ middle intervention and radiotherapy+ late intervention groups. Survival analysis was performed with Kanplan-Meier method. Results The median survival of 192 patients with oligometastatic stage Ⅳ NSCLC was 14. 50 months, and the 1-,2-and 3-year survival rates were 57. 4%,24. 0% and 10. 7%, respectively. The median survivalin the chemotherapy alone, radiotherapy+ early intervention, radiotherapy+ middle intervention and radiotherapy+late intervention groups was 10,21,18 and 13 months, respectively. The 1-year survival rates were 34%, 73%,71% and 51%,10%,40%,32% and 13% for the 2-year survival rates, and 0%,24%,16% and 3%for the 3-year survival rates ( P=0. 000) . The median survival of patients with radiotherapy dose ≥ 60 Gy and< 60 Gy was 21 and 13 months, 76% and 53% for the 1-year survival rates, 34% and 21% for the 2-year survival rates, and 17% and 10% for the 3-year survival rates ( P=0. 002 ) . Conclusion Early interventional therapy and high-dose radiotherapy can improve the local control rate and prolong the survival time of patients with oligometastatic stage Ⅳ NSCLC.
