RESUMO
Objective To investigate clinical therapeutic effect of zoledronic acid combined with chemotherapy to senile lung cancer with bone metastases.Methods Totally 80 cases of senile lung cancer patients with bone metastasis were randomly divided into control group and combined group,40 cases in each group.Limitation of activity to the situation,release of bone pain,adverse e-vents and side effects were observed.Serum Ca2+ concentration,alkaline phosphatase (AKP)levels and the levels of serum inflam-matory cytokines TNF-α,IL-1βwere detected.Results Limitation of activities and pain of patients with combined treatment was significantly ameliorated compared to control group (P <0.05).Serum Ca2+ ,AKP and TNF-α,IL-1β levels were significantly de-creased in patients with combined group in time-dependent manner,and which were significantly lower than control group.Bone ad-verse events and side effects in patients with combined treatment were significantly lower than in patients with control group.Con-clusion Zoledronic acid combined with chemotherapy can enhance the efficacy of chemotherapy,effectively relieve the limitation of activities and pain symptoms and reduce the incidence of bone adverse events and adverse reactions.The effect may be related to the decrease of serum calcium and the inflammatory cytokines.
