肺癌病人放射性核素骨显像

本文利用放射性核素骨显像研究56例肺癌的骨转移情况。其阳性率为62％,肺癌病人骨显像阳性发现早,常在术前及术后8个月以内,且常为多发灶。骨显像被认为是一高灵敏而非特异的检查骨转移的方法,故需仔细判断骨显像中所示阳性区域病灶。可使其假阳性降低为零。骨显像所示骨转移尤其是“隐匿性骨转移”似应与传统骨转移灶相区分,并对其性质、预后及治疗方法进行深入研究,从而使肺癌病人的骨转移得到早期、合理的治疗。

Bone Scintigraphy in Lung Cancer

Bone metastasis was investigated by bone scintigraphy in 56 patients with histological proven lung cancer. The positive rate was 62%. Bone metastasis can be detected by means of scan-positive in lung cancer patient as early as 8 months before or after, surgery in a majority of instances. Multiple foci of bone metastases were the rule at large. Although bone scintigraphy is sensitive enough but not specific in the detection of bone metastasis, careful scrutiny of the implicated area of the scan may minimize the false positive rate to zero. Bone metastases by scintigraphy, especially subtle lesions are apparently distinctive from classic bone metastases. Further studies are needed to investigate their nature and prognosis in order to properly implement timely treatment.
