Objective To explore the effect of 153Sm-EDTMP combined ibandranate in treatment of osseous metastasis of lung cancer.Methods 100 patients with osseous metastasis of lung cancer were randomly divided into two groups.The patients received intervenous drop infusion of 153Sm-EDTMP and ibandranate in treatment group( n =52).The patients received therapy with 153Sm-EDTMP in control group( n =48).The differentces of effect of odynolysis,locomotor activity,improvement of quality of life,recovery of osteolysis,toxical and adverse reaction between two groups were compared.Results The overall response rate 94.2％ in treatment group was significantly higher than that 64.5 ％ in control group( x2 =4.78,P ＜ 0.0.5 ) ;The activity to improve situation 82.6％ in treatment group was significantly higher than that 64.5％ in control group( x2 =4.13,P ＜ 0.05 ) ;The total effective rate of quality of life improve the situation 84.6％ in treatment group was significantly higher than that 62.5％ in control group( x2 =4.58,P ＜0.05 ) ;The side effects had no significant difference between two groups ( x2 =0.345,P ＞ 0.05).Conclusion The treatment of 153Sm-EDTMP combined with ibandranate in the treatment of osseous-metastasis of lung cancer was effective for relieving pain,improvement locomotor activity,improvement of quality of life,recovery of osteolysis.

Objective To investigate the effect of iodine-131(131Ⅰ) therapy on patients with differentiated thyroid carcinoma concurrent metastases.Methods 50 cases with differentiated thyroid carcinoma after operation ac-cording to metastaticsites were given one of fractionated treatment,a total removal of dose(370～740)×107Bq,inter-val of 4 months.Results 35 of 50 patients(70.O%) had successful ablation of residual thyroid tissue after the first administration of radioiodine.Metastatic carcinoma in 18 cases,6 cases(33.3%) were cured,effective treatment was shown in 8 cases(44.4%)and treatment failure in 4 cases(22.2%);Thyroid metastasis before treatment were signifi-cantly higher than non-HTG thyroid metastasis(t=2.715,P<0.01),decreased significantly after treatment(t=2.844,all P<0.01);The contents of CD4+、CD8+、CD4+/CD8++ in treatment group after treatment[(26.5±4.7)%、(39.4±5.7)%、(0.6±0.4)%] were lower than before treatment[(38.3±5.6)%、(29.8±6.9)%、(1.4±0.5)%](t=2.345,t=2.244,t=2.451,all P<0.05).Conclusion Treatment with multiple hlsh doses of 131Ⅰ was safe and effective with little adverse side-effect.
