Solid tumors frequently metastasize to bone. This results in debilitating skeletal complications such as intractable bone pain, pathologic fractures, spinal cord compression, and hypercalcemia. Patients frequently require palliative radiation therapy or orthopedic surgery. Bisphosphonates have been shown to delay the incidence and decrease the frequency of skeletal-related events. Zoledronic acid is the only bisphosphonate that has provided benefits for patients with bone metastases secondary to a broad range of solid tumors. Among patients with metastatic breast or prostate cancer, zoledronic acid has demonstrated significant reductions in pain and skeletal morbidity compared with placebo. Zoledronic acid has also shown significant reductions in skeletal morbidity in patients with lung cancer or other solid tumors compared with placebo. Zoledronic acid is generally well tolerated. Flu-like symptoms which are manageable with standard treatment can occur. Renal monitoring is recommended, with dose reductions for patients with renal dysfunction. Osteonecrosis has been reported in patients receiving bisphosphonates and might be avoidable with appropriate dental care.

Patients with metastatic bone disease are at risk for developing skeletal-related events that can negatively influence quality of life, contributing to loss of autonomy and functional capabilities. Bisphosphonates have become an important component in the treatment of patients with bone metastases as they delay the onset and reduce the risk of skeletal-related events and also palliate or control bone pain in multiple cancer types, thus preserving quality of life. Zoledronic acid has proven efficacy and safety in patients with bone lesions from breast cancer, prostate cancer, lung cancer, and other solid tumors, as well as in patients with multiple myeloma. Current data suggest that early treatment with zoledronic acid (before the onset of bone pain) may provide additional clinical benefits and also positive effects on survival in subsets of patients who have elevated levels of N-telopeptide of type I collagen (NTX), a biochemical marker of bone resorption. Studies have shown that in patients with breast cancer, prostate cancer, lung cancer, or other solid tumors, normalization of elevated levels of NTX was observed in the majority of patients who received zoledronic acid. Furthermore, normalization of NTX values correlated with extended survival.

Thirty-65% of patients with metastatic lung cancer will develop bone metastasis. Bone metastases cause considerable skeletal morbidity, including bone pain, pathologic fractures, spinal cord compression and it is necessary to develop the effective treatment against bone metastasis. We reported cases of non-small-cell lung cancer who had dramatic improvements of pathologic fractures with gefitinib. In addition, gefitinib treatments elevated levels of serum Bone ALP, ICTP and ratio of Bone ALP/ICTP in patients with bone metastasis. Gefitinib may have inhibitory effects against bone resorption as well as antitumor effects.

Many solid tumors metastasize to bone, leading to debilitating skeletal complications such as intractable bone pain and pathologic fractures. Patients who experience a skeletal-related event (SRE) are at higher risk for subsequent events. After an SRE such as a pathologic fracture, spinal cord compression, or the requirement for orthopedic surgery or palliative radiation therapy, a patient's quality of life and functional independence could decline substantially. Prevention or delay of skeletal complications provides clinical benefit to patients with bone metastases secondary to solid tumors. Treatment for the prevention of the first SRE might substantially improve patients' quality of life, functional independence, and pain throughout the course of their disease. Bisphosphonates have shown a palliative benefit in this setting. In particular, zoledronic acid is the only bisphosphonate that has provided benefits for patients with bone metastases secondary to a broad range of solid tumors. Among patients with metastatic breast or prostate cancer, zoledronic acid has demonstrated significant reductions in pain and skeletal morbidity compared with placebo. Zoledronic acid has also shown significant reductions in skeletal morbidity in patients with lung cancer or other solid tumors compared with placebo. Pamidronate, oral clodronate, and ibandronate compared with placebo have each shown significant benefits in reductions of pain and skeletal complications for patients with metastatic breast cancer. Further improvements in the management of skeletal health in patients with malignant bone disease could be achieved through ongoing bisphosphonate investigations to optimize dose, timing, and duration of treatment.

Bone metastases are common in patients with advanced-stage cancer; they can lead to skeletal complications (ie, pathologic fractures, spinal cord compression, tumor-induced hypercalcemia, and severe bone pain) that often require orthopedic surgery or palliative radiation therapy and negatively affect quality of life. The primary role of bisphosphonates for the management of bone metastases in patients with advanced-stage cancer is the prevention of these painful skeletal complications. In placebo-controlled trials, a number of bisphosphonates, including oral clodronate, oral and intravenous (I.V.) ibandronate, I.V. pamidronate, and I.V. zoledronic acid, have been shown to significantly reduce skeletal complications in patients with bone metastases from breast cancer. Furthermore, zoledronic acid provided benefit compared with pamidronate in patients with bone metastases from breast cancer in a large, comparative trial. Zoledronic acid also provided long-term benefits in randomized placebo-controlled trials in patients with bone metastases from prostate cancer, lung cancer, and other solid tumors, whereas other bisphosphonates that have been investigated have failed to demonstrate objective long-term benefits in placebo-controlled trials. In addition, although systemic analgesics and radiation therapy are primary treatments for the management of bone pain, bisphosphonates can also play an important secondary role in reducing bone pain associated with skeletal metastases. Notably, several economic analyses of bisphosphonate therapy have demonstrated that these agents are cost-effective by reducing health-care costs associated with skeletal complications and providing clinically significant quality of life benefits to patients with malignant bone disease.

Healthy donors (HDs) who were mobilized using lenograstim (LENO) and who were undergoing peripheral haematopoietic progenitor cell collection with apheresis (HPC-A) were enrolled in a surveillance protocol. In all, 184 HDs have been assessed with a median follow-up of 62 months (range 2-155). HDs received LENO at a median dose of 10 microg/kg (range 5-15). Bone pain was reported as the most frequent short-term adverse event (71.2%). Other commonly observed short-term symptoms included fatigue (19.0%), fever (5.4%), headache (27.7%), nausea (12.0%) and insomnia (22.3%). Spleen size increased in 4.3% of the donors. No vascular disorders or cardiac disease occurred. Long-term follow-up included monitoring of adverse events, neoplastic disease or other pathologies. Transit ischaemic attack occurred in one donor (39 months post-donation). One autoimmune event was reported at 28 months post-recombinant human granulocyte (rhG)-CSF (ankylosing spondylitis); one donor with a history of chronic obstructive pulmonary disease developed secondary polyglobulia (50 months post-rhG-CSF). One donor was diagnosed with lung cancer at 19 months post-donation. No haematological disease was observed. In conclusion, the short-term safety appears to be verified, whereas, although the study identified no increased risks of malignancy among HDs who received rhG-CSF, long-term safety requires more complete data sets, especially a longer follow-up and a larger number of HDs.

Lung cancer is the leading cause of cancer death in the United States. Fifteen percent of patients are asymptomatic at diagnosis. Symptoms usually indicate advanced disease. Signs include chronic cough, hemoptysis, wheezing, dyspnea, vague chest pain, hoarseness, pleural effusion, cardiac arrhythmias and bone pain. Significant surgical advances have reduced operational mortality rate. Early detection and surgery can increase survival rates for some patients.

Bone metastases occur in 20-40% of patients with lung cancer. Recent studies demonstrate a direct antiproliferative effect of 3rd generation bisphosphonates (BPs) on lung tumors, which may influence the survival. Therefore, we examined the clinical impact of zoledronic acid (ZOL; Zometa), a 3rd generation BP, with a focus on the survival, time to progression and pain effect in lung cancer patients with bone metastases. Lung cancer patients (n = 144, Stage IV) with evidence of metastasis bone scan were included. Eighty-seven of 144 experienced bone pain and received ZOL, 4 mg i.v. every 21 days (Group A), whereas the other 57 patients received no ZOL (Group B). All patients were treated with a combination chemotherapy consisted of docetaxel 100 mg/m(2) and carboplatin AUC = 6. It was found that Group A had a statistically significant longer survival (p < 0.01) when compared to Group B. A statistically significant positive correlation was found between the number of cycles of therapy with ZOL and total patient survival (p < 0.01, Pearson correlation) and time to progression (p < 0.01). Pain effect of ZOL had no significant difference between the 2 groups of patients (p > 0.05). Urine N-telopeptide of type I collagen (NTx) levels decreased in patients with NTx < or = 29 nM BCE/mM creatinine at baseline after treatment with ZOL. The results of our study suggest that the addition of ZOL increases overall survival in lung cancer patients with bone metastases. The longer period of receiving ZOL, the better effect on survival and time to progression.

Finger clubbing, which involves distal phalanx thickening and nail convexity, has been known since antiquity. Observations made in modern times by Bamberger (1889), Pierre Marie (1890), and other investigators led to identification of various causes of this digital anomaly which can be the first manifestation of a severe organic disease. Undoubtedly, this somatic abnormality, often associated with arthralgia and bone pain (full-blown hypertrophic osteoarthropathy -- HOA), is most often a harbinger of lung cancer. Paraneoplastic HOA is probably the best known and the most extensively studied paraneoplastic syndrome in human pathology. The familial or idiopathic HOA (pachydermoperiostosis) appears at puberty and is not associated with other underlying diseases. We present the case of a 58-year-old male with HOA, associated with spinocellular lung cancer, who survived 25 years after pneumonectomy.

Approximately 30-40% of NSCLC patients develop bone metastases. Bone metastases are associated with a significant increase in skeletal-related events (SREs), including severe bone pain, hypercalcemia, pathological fractures, spinal cord compression. These SREs result in impaired mobility, reduced quality of life, and frequently require therapeutic intervention (radiation therapy, surgery and systemic treatments). The normal balance of formation of new bone by osteoblasts and the resorption of old bone by osteoclasts becomes imbalanced and/or uncoupled, leading to the development of lesions that are osteolytic, osteoblastic, or a combination of both. The current National Comprehensive Cancer Network (NCCN) Clinical Practice Giudelines in Oncology recommend palliative external-beam radiotherapy for the treatment of bone metastases in patients with NSCLC and healthcare professionals treating such patients are urged to consider bisphosphonate therapy. Zoledronic acid is the first and only bisphosphonate that has proven efficacy for the treatment of bone metastases from a broad range of solid tumor types, including lung cancer.
