Analysis of bone imaging results of 562 primary lung carcinoma patients

Objective: To evaluate regularity of bone metastasis with bone imaging in different histological types of lung cancer patients. Methods: 99Tcm-methytene diphosphonate (99Tcm-MDP) whole body bone imaging was performed in 562 patients who had been diagnosed primary lung cancer. The bone imaging results of different pathological types of lung cancer were analyzed. Results: Average incidence rate of bone metastasis in all types of lung cancer is 43.06%. Pulmonary adenocarcinoma and small cell carcinoma has higher incidence rate, 45.16% and 55.4% respectively. Incidence rate of bone metastasis in adenosquamous carcinoma and squamous cell carcinoma were 37.93% and 35.19% respectively, less than that of adenocarcinoma and small cell carcinoma. Conclusion: The incidence rate of bone metastasis of lung cancer is higher; lung adenocarcinoma and small cell carcinoma are more susceptible to metastasis to bones. Radionuclide whole body bone imaging is the preferred method for early diagnosis of bone metastasis, and helps judge the progress of disease, select appropriate treatment programs, improve the patients live quality and prolong life expectancy.
