Abstract:

Objective To investigate the characteristics of bone metastasis, prognosis and treatment strategies of non-small cell lung cancer(NSCLC) patients in China. Methods Totally 103 metastatic NSCLC patients with bone as the first metastatic organ seen between July 1, 2010 and Dec. 31, 2013 were retrospectively reviewed. Clinical pathologic characteristics and treatment outcomes were evaluated in the 103 cases. Results Median age of the patients was 59(32~82) years. Among them, 28 patient had bone metastasis as the only relapse site and the remaining were accompanied by involvement of other locations. Most bone metastases(95.1%) were osteolytic. Overall survival of NSCLC bone metastases without visceral metastases was significantly longer than bone metastases with visceral metastases(18 months vs 14 months, P=0.048). Most NSCLC bone metastases(77.7%) were treated with chemotherapy, the response rate was 32.5%, and the clinical benefit rate was 58.8%. In terms of time to progression, there was significant difference between patients who received first-line chemotherapy and those who received the first-line targeted therapy(P=0.000). Conclusion Patients just with bone metastases had better prognosis than bone metastases patients with visceral metastases. Patients with bone metastases should receive individualized anti-cancer treatment.
