【 摘 要 】

Purpose We explored and compared the clinical effects of whole-brain radiotherapy (wbrt) with and without elemene liposomes in patients with multiple brain metastases from non-small-cell lung carcinoma (nsclc). Methods We retrospectively analyzed 62 patients with multiple brain metastases from nsclc who received wbrt (30 Gy in 10 fractions) at Shengjing Hospital of China Medical University from January 2012 to May 2013. In 30 patients, elemene liposomes (400 mg) were injected intravenously via a peripherally inserted central catheter for 21 consecutive days from the first day of radiotherapy. Overall survival (os) and nervous system progression-free survival (npfs) for the two groups were compared by Kaplan–Meier analysis. Factors influencing npfs were examined by Cox regression analysis. Chi-square or Fisher exact tests were used for group comparisons. ResultsThe median os was 9.0 months in the wbrt plus elemene group and 7.8 months in the wbrt-alone group ( p= 0.581); the equivalent median npfs durations were 5.2 months and 3.7 months ( p= 0.005). Patient treatment plan was an independent factor associated with npfs ( p= 0.002). Tumour response and disease-control rates in the wbrt plus elemene group were 26.67% and 76.67% respectively; they were 18.75% and 62.5% in the wbrt group ( p= 0.452). Compared with the patients in the wbrt-alone group, significantly fewer patients in the wbrt plus elemene group developed headaches ( p= 0.04); quality of life was also significantly higher in the wbrt plus elemene group both at 1 month and at 2 months ( p= 0.021 andp= 0.001 respectively). ConclusionsThe addition of elemene liposomes to wbrt might prolong npfs in patients with multiple brain metastases from nsclc, while also reducing the incidence of headache and improving patient quality of life.
