Squamous cell carcinoma antigen (SCC) is isolated as a heterologic antiserum against cells of cervical carcinoma in 1977 by Kato u Torigoe. It is not specific for cervical carcinoma and rises up in cases of carcinoma vulvae, esophageal carcinoma, carcinoma pulmonum, ext. High levels are detected also in psoriasis, sarcoidosis, liver and kidney diseases. SCC is not a reliable marker in diagnosis and screening. Some trials show a correlation between the preterapeutic levels of SCC and the prognosis, but none of them is randomized. So the predictive value of SCC, except the nodal metastasis, stays on a low level of evidence and recommendation. On the contrary is the data for SCC as a monitoring marker for a local recurrence in patients after primary treatment. The sensitivity and specificity of the marker for a cervical carcinoma recurrence varies between 56 and 86% sensitivity and 83 and 100% specificity. A new possibility for an early recurrence finding in patients with rising SCC gives FDG PET/CT. The method is highly potent in detection of local recurrence and distant metastasis in patients with cervical carcinoma and is suitable for staging, restaging and monitoring of these patients.
鳞状细胞癌抗原(SCC)于1977年由加藤和鸟越从针对子宫颈癌细胞的异种抗血清中分离出来。它并非子宫颈癌所特有,在外阴癌、食管癌、肺癌等病例中也会升高。在银屑病、结节病、肝脏和肾脏疾病中也能检测到高水平的SCC。SCC在诊断和筛查中并非可靠的标志物。一些试验表明SCC的治疗前水平与预后之间存在相关性,但均未进行随机分组。因此,除了淋巴结转移外,SCC的预测价值在证据和推荐水平上仍较低。相反,SCC作为原发性治疗后患者局部复发的监测标志物的数据则不同。该标志物对子宫颈癌复发的敏感性和特异性在56%至86%的敏感性和83%至100%的特异性之间变化。FDG PET/CT为SCC升高的患者早期发现复发提供了一种新的可能性。该方法在检测子宫颈癌患者的局部复发和远处转移方面非常有效,适用于这些患者的分期、再分期和监测。
