Objective To evaluate the efficacy of zoledronic acid combined with radiotherapy for bone meta-static cancer. Methods 71 cases with bone metastatic cancer were randomly divided into observation group (40 ca-ses) and control group (31 cases). The observation group was treated with zoledronic acid, 4 mg intravenously and local radiotherapy. The control group was treatd by radiotherapy alone. Results Pain relief was noted in 90% pa-tients in the observation group and 83.9% in the control group, respectively. The statistical difference was not signif-icant(P > 0.05). After the treatment had finished 3 months pain alleviation situation:Pain relief was noted in 87.5% patients in the observation group and 67.7% in the control group, respectively. The difference between the two groups was significant(χ2 =4.09, P =0.043). No serious radiotherapy and serious adverse drug reactions was found. Conclusion Zoledronic acid combined with radiotherapy was superior to radiotherapy alone for metastatic cancer bone pain relief, analgesic effect maintain a longer time.

Objective To evaluate the efficacy and safety of induction chemotherapy and three-dimensional conformal radiation (3D-CRT) combined with endostar in the treatment of locally advanced non-small cell lung cancer (NSCLC).Methods Thirty patients with locally advanced NSCLC were enrolled and divided into observation group (15 cases) and control group (15 cases).In the observation group,the patients received induction chemotherapy and 3D-CRT combined with endostar.Chemotherapy:Vinorelbine 25mg/m2 on day 1 and 8,DDP 30mg/m2 on day 2 to 4.Endostar 7.5mg/m2 on day 1 to 14,which was used again after 7 days for 2 to 4 cycles.In the control group,the patients received induction chemotherapy and 3D-CRT at the same dosage.All patients were treated with 3D-CRT and the prescription dose was 60 ～ 68Gy per fraction.The responses were evaluated according to WHO criteria.The shortterm efficacy between the 2 groups was compared.Results The overall effective rate of the two groups were 66.7％ and 60.0％,respectively (P ＞ 0.05).The median progression-free survival time was 12 months in the observation group and 10 months in the control group.The median survival time was 20 months in the observation group and 18 months in the control group.The 1 year overall survival rate was 80.0％ in the observation group and 73.3％ in the control group(P ＞ 0.05).The main toxicities in the two groups were marrow suppression,gastrointestinal symptoms,acute radiation pneumonitis and acute radiation esophagitis.There was no significant difference between the two groups (P ＞ 0.05).Conclusions The combination of endostar with induction chemotherapy and 3D-CRT can improve the short-term efficacy rate of locally advanced NSCLC,the adverse events of which are tolerable,but the improvement is not significant in both groups.The result pending further randomized multi-center phase Ⅲ clinical study.
