用放射免疫法测定膀胱癌治疗后病人尿中的GEA。治疗前未接受放射治疗的有28例,其中膀胱无残余癌16例,凡无尿路感染者(11例)CEA皆阴性,有尿路感染者皆呈阳性;另12例膀胱有残余癌,无论有无尿路感染,CEA皆呈阳性。另一组膀胱癌病例7人,均无尿路感染,在治疗前后均作CEA测定,其中5例治疗成功者,其CEA均显示下降,反之,2例治疗失败者均增加。总之,在膀胱癌患者只要不合併尿路感染,测定尿中CEA,对诊断和治疗后观察,非常有价值。
Radioimmunoassay in the urine of patients with bladder cancer after treatment of GEA. There were 28 cases without radiation treatment before treatment, of which there were 16 cases with no residual bladder cancer and all cases without urinary tract infection (all 11 cases) were negative with urinary tract infection, while the other 12 cases had residual cancer, CEA was positive regardless of urinary tract infection. Another group of 7 cases of bladder cancer without urinary tract infection, before and after treatment were CEA determination, of which 5 cases of successful treatment, the CEA showed decreased, on the contrary, two cases of treatment failure were increased. In short, as long as patients with bladder cancer do not merge urinary tract infection, determination of urinary CEA, the diagnosis and post-treatment observation, very valuable.
