Combined chemotherapy of zoledronic acid and pamidronate in the treatment of bone metastases from nonsmall cell lung cancer and the effects on pain stress and bone metabolic indices.

Objective: We conducted this paper to decipher the efficacy of the combined chemotherapy of zoledronic acid and pamidronate in treating bone metastases from nonsmall cell lung cancer (NSCLC) and the effects on pain stress and bone metabolic indices. Methods: Patients with bone metastases from NSCLC were allocated into Group A and Group B. Patients in the Group A were administrated with pamidronate combined chemotherapy and patients in the Group B were administrated with zoledronic acid combined chemotherapy. The efficacy, pain symptom scores, quality of life scores, serum inflammatory factor, serum bone metabolic indices, serum pain stress indicators, and the occurrence of adverse effects were compared in patients of the two groups. Results: The total effective rate of treatment was higher in the Group B than in the Group A. After treatment, reduced Numerical Rating Scale scores and elevated Karnofsky Performance Score score, reduced serum levels of N‐terminal mid‐fragment of osteocalcin, N‐terminal propeptide of type I procollagen, bone‐specific alkaline phosphatase, and type I collagen hydroxyl terminal peptide β special sequence, reduced serum levels of C‐reactive protein, procalcitonin, tumor necrosis factor‐α, and interleukin‐6, as well as decreased levels of bradykinin, substance P, neuropeptide Y, and β‐endorphin were found in the Group B versus the Group A. No notable difference was witnessed in the rate of adverse reactions between the Group A and the Group B. Conclusion: Zoledronic acid combined with chemotherapy can effectively treat bone metastases of NSCLC and improve pain stress and bone metabolic status, which has value that can be promoted and applied in clinical treatment.
