作者对166例以各种抑制雄性素治疗的转移性前列腺癌用最初骨扫描的方法来判断预后。在静脉注入~(99m)Tc-MDP 740MBq(20mCi)2～3小时作全身骨骼扫描,依据转移灶的数目或范围(EOD)作半定量分级系统来分析EOD与生存的关系。EOD分五级,其中O:正常或因良性骨病所致的异常;Ⅰ:骨转移灶不到6处,每处大小不及一个椎体的50%(一处病灶有一个椎体大将计为2个病灶);Ⅱ:
The authors evaluated the prognosis of 166 cases of metastatic prostate cancer treated with various androgen-reducing prostate cancers using an initial bone scan. A total body bone scan was performed by intravenously injecting ~(99m)Tc-MDP at 740 MBq (20mCi) for 2 to 3 hours. The relationship between EOD and survival was analyzed by a semi-quantitative grading system based on the number or range of metastatic lesions (EOD). EOD is divided into five grades, in which O: normal or due to benign bone disease; I: less than 6 bone metastases, each size is less than 50% of a vertebral body (one lesion with one vertebral body will count as 2 lesions); II:
