Objective To investigate the efficacy and toxicity of chemotherapy of modified INP regimen in the treatment of adenocarcinoma with brain metastases. At the same time,to explore the relationship between expression of β-tubulin-Ⅲ in NSCLC biopsies and sensitivity to this modified INP regimen. Methods The clinical data of 15 adenocarcinoma with brain metastases patients who had been admitted to the first affiliated hospital of Guangzhou medical university from April 2010 to January 2013 were retrospectively analyzed. All patients received modified INP regimen.RECIST 1.0 was taken to know the result. Results For brain metastasis of the 15 patients, complete response (CR) and partial response(PR) were 1 and 5 patients, respectively. 4 patients were stable disease (SD) and progression disease(PD) in 5 patients. The overall response rate(ORR) was 40% and the disease control rate(DCR) was 66.7%. The toxicity was mild. Furthermore, we found NSCLC patients with low β-tubulin-Ⅲexpression had better ORR than those with high expression. Conclusion The modified INP regimen is effective and well-tolerable for brain metastases of adenocarcinoma. The β-tubulin-Ⅲ expression may be associated with the efficacy of this regimen.
