  • Title: Skeletal disease contributes substantially to morbidity and mortality in patients with lung cancer.
    Author: Hirsh V.
    Journal: Clin Lung Cancer; 2009 Jul; 10(4):223-9. PubMed ID: 19632938.
    Abstract:
    Lung cancer is one of the most common cancers diagnosed worldwide. As the disease progresses, patients with lung cancer can develop metastasis to the bone. However, because early-stage bone disease may be asymptomatic, bone metastases often go undiagnosed, resulting in delayed initiation of treatment to prevent skeletal complications. In the absence of bone-targeted therapies, patients with metastatic bone disease are at increased risk for potentially debilitating skeletal-related events (SREs) including pathologic fracture, spinal cord compression, hypercalcemia of malignancy, and the requirement for surgery or radiation therapy to bone. The majority of patients with bone metastases from lung cancer will develop SREs, and this number is expected to increase with the improvement of primary therapies that are prolonging the lives of patients. Zoledronic acid is the only bisphosphonate that has been extensively studied in patients with bone metastases from lung cancer, and it has demonstrated efficacy in delaying the onset and reducing the risk of SREs in this setting. Preventing SREs with zoledronic acid may preserve the quality of life and functional independence of these patients. Recent exploratory analyses of a phase III study in patients with bone metastases from lung cancer or other solid tumors revealed that zoledronic acid also normalizes biochemical markers of bone metabolism and may also improve survival in specific patient subsets. Additional ongoing clinical trials are assessing further benefits and antitumor activity of zoledronic acid in the adjuvant setting in the prevention of bone metastases in patients with lung cancer.
