Application value of radionuclide bone imaging in patients with primary pulmonary cancer before and after treatment / 国际肿瘤学杂志

ABSTRACT

Objective To probe the application value of radionuclide bone imaging in pre-treatment selection of therapeutic plan and regular post-treatment follow-up of patients with primary pulmonary cancer.Methods 810 patients with primary pulmonary cancer had radionuclide bone imaging respectively before the treatment. The follow-up radionuclide bone imaging was performed in 492 cases that were treated by surgery in 2 years after the operation. For 318 cases that were treated by non-surgery way,only 142 cases that had no skeletal metastases had follow-up radionuclide bone imaging in 2 years after the treatment. Results 179 cases (22.1%) had skeletal metastases in 810 cases. Multiple skeletal lesions were found in 157 cases and single skeletal lesion found in 22 cases. The majority sites of skeletal metastases were ribs, vertebrae column and pelvis. 57 cases that were treated by surgery had new skeletal lesions in 2 years after the operation. For non-surgery patients,79 cases had new skeletal lesions in 2 years after the treatment. Conclusion Radionuclide bone imaging is useful in the selection of therapeutic plan and staging of primary pulmonary cancer before the treatment.Regular bone imaging after the operation is helpful to detect early bone metastasis and choose the therapeutic plan, and should be regarded as a foremost method to detect the skeletal lesion. Radionuclide bone imaging after the non-surgery treatment maybe help us to conclude the prognosis of the patients.
