282例癌全身骨显像的骨转移发生率及好发部位分析

The Incidence of Metastatic Carcinoma of Bone and Its Predilection Site An Analysis of 282 Cases on Radionuclide Image

对２８２例肿瘤患者全身骨显像资料进行骨转移率和好发部位分析。结果：（１）骨转移率为７１．３％，文献报道为２４％～７８．７％；其相差较大的主要原因与鼻咽癌高发区，显像仪器是否先进和癌是否晚期有关。（２）好发部位分析，除按文献方法对脊柱、胸廓、骨盆、四肢骨及颅骨转移灶的总体分析外，还对单个椎体和单根肋骨进行了详细的对比分析。认为这种单个分析可明确排定好发部位依次为腰椎、胸椎，肋骨和颈椎，不同于文献报道的肋骨。

An analysis of the incidence of metastatic tumor of bone and its predilection site was made on radionuclide images of bones of the whole body in 282 patients with carcinoma.The results showed:(1)The rate of metastasis to bone was 71.3%,while it was 24%-78.7% reported in literature.The cause of difference might be correlated to the predilection area of carcinoma of nasophargnx,the availability of imaging apparatus and the stage of the carcinoma.(2)The analysis of predilection sites revealed that besides general analysis on the metastases of the vertebral column on those of the thorax,pelvis ,bone of the limbs and skull according to literature,detailed comparative analysis was made on individual vertebra and ribs.It is suggested that the latter analysis may confirm and arrange the predilection sites in order,being lumber vertebrae,thoracic vertebrae,ribs and cervical vertebrae respectively and different from what reported in literature,being ribs,lumber.vertebrae and thoracic vertebrae respectively.
