扁平上皮癌相关抗原(血清SCC抗原)是诊断扁平上皮癌的肿瘤标记物。作者测定了3例膀胱扁平上皮癌手术前后及复发治疗前后的血清SCC抗原值,认为该抗原对观察治疗效果及估计预后有重要意义。方法用RIA2抗体法(正常值<2.0ng/ml)或RIA固定法(正常值<1.5ng/ml)测定。病例 3例扁平上皮细胞癌均为男性,年龄48～77岁,PT_4 1例PT_(3b)2例。术前测定SCC抗原2例,分别为13ng/ml、8.4ng/ml。3例均作了膀胱部分切除术,其中2例加盆腔淋巴结清扫,1例加肾及输尿管切除术。术后SCC抗原分别下降为0.9ng/ml、2.2ng/ml、2.1ng/ml。3例术后均复发,血清SCC抗
Squamous cell carcinoma associated antigen (serum SCC antigen) is a tumor marker for the diagnosis of squamous cell carcinoma. The authors measured the serum SCC antigen value of 3 cases of squamous cell carcinoma of the urinary bladder before and after surgery and relapse treatment. It is believed that the antigen is of great significance for observing the treatment effect and estimating the prognosis. Methods were determined using RIA2 antibody (normal <2.0 ng/ml) or RIA fixation (normal <1.5 ng/ml). Case 3 cases of squamous cell carcinoma were male, aged 48 to 77 years old, PT_4 1 case of PT_(3b) 2 cases. Preoperative determination of SCC antigen in 2 cases, respectively, 13ng/ml, 8.4ng/ml. All 3 cases underwent partial cystectomy, including 2 cases of pelvic lymph node dissection and 1 case of renal and ureteral resection. Postoperative SCC antigens decreased to 0.9 ng/ml, 2.2 ng/ml, and 2.1 ng/ml, respectively. Three cases relapsed after surgery, serum SCC resistance
