One group wastreated with radiotherapy alone, the other was treated with a combination of radiotherapy and intravenousinjection of 10 % Brucea javanica emulsion. The results showed that the median survival duration (15months in the test group, 10 months in the control group) and the quality of life of the patients in the com-bined (test) group was much better than in the radiotherapy alone (control) group. The results suggest the10 % Brucea javanica emulsion exhibits a synergic action with the radiotherapy in the treatment of brain-metastasis as a complication of lung cancer.展开更多

This study explored the clinicopathological characteristics of the G719 X mutation and investigated the efficacy of EGFR-tyrosine kinase inhibitor(TKI) treatment and chemotherapy in patients with the G719 X mutation; the survival rate after these different treatment modalities were then analyzed in order to provide evidence for clinical treatment.Methods Clinical data of 41 patients with the G719 X mutation admitted in the Beijing Chest Hospital, Capital Medical University from September 2014 to July 2018, were collected and the EGFR mutations were detected by amplification refractory mutation system-polymerase chain reaction(ARMS-PCR). The clinicopathological characteristics of the G719 X mutation were analyzed, and the relationship among the G719 X mutation, the efficacy of different treatment modalities, and the progression-free survival(PFS) was analyzed. Results Of the 41 cases, 24(58.5%) were G719 X single mutations and 17(41.5%) were compound mutations, including G719 X/S768 I, G719 X/L861 Q, G719 X/19 del, and G719 X/c-Met compound mutation. The objective response rate(ORR) of first-line EGFR-TKI therapy was 50%(6/12), the disease control rate(DCR) was 83.3%(10/12), and the median PFS(mPFS) was 9 months. After resistance to EGFR-TKI in the previous treatment, the ORR(71.4%, 5/7) and DCR(100%, 7/7) were still high following EGFR-TKIs, by an mPFS of 8 months. The ORR of chemotherapy was 33.3%(2/6), the DCR was 100%(6/6), and the mPFS was 6 months. Conclusion G719 X is an uncommon mutation of the EGFR gene and is sensitive to many EGFR-TKIs. It can be treated with the second-or third-generation EGFR-TKIs after resistance to the first-generation EGFR-TKIs. G719 X mutation also showed favorable effect to chemotherapy.展开更多
