62例肺癌骨转移

Sixty-two cases of lung cancer with bone metastasis

报道62例肺癌骨转移。96．8％的患者有骨痛。63．3％的患者骨痛出现时间晚于呼吸道症状。肺癌骨转移的部位以胸骨最常见（占70．1％），其次为脊柱（69．3％）和骨盆（45．2％）。骨x线片对病灶的检出率为64．3％，且以单灶为多（68．6％），平均检出病灶数为1．6±0．2个。骨核素显像的检出率为100％，且能检出多灶（占59．1％），平均检出病灶数为2．8±0．1个。骨X线片和核素显像结合应用可提高骨转移灶的定性、定位诊断。

62 cases of lung cancer with bone metastasis were reported. 96.8% of them had ostalgia and bone tenderness. The common sites of skeletal metastasis were sternum (70.1% ), spine (69. 3% ) and pelvis (45. 2% ) . 64. 3% of lesions could be found in bone x-ray examination, 68. 6% of them were solitary. The mean discovering lesions were 1. 6 ±0. 2. The sensitive of bone scintigraphy was 100% in bone metastasis, 59. 1 % of them were multiple lesions, and the mean discovering foci were 2. 8±0.1. The combination of bone x-ray examination and scintigraphy contributed to diagnose bone metastasis of lung cancer.
