  • Title: Serum squamous cell carcinoma antigen levels in invasive squamous vulvar cancer.
    Author: Rose PG, Nelson BE, Fournier L, Hunter RE.
    Journal: J Surg Oncol; 1992 Jul; 50(3):183-6. PubMed ID: 1619942.
    Abstract:
    Squamous cell carcinoma (SCC) antigen levels were studied in 34 patients with primary (N = 27) or recurrent (N = 7) SCC of the vulva. In primary disease, the SCC antigen level was greater than 2.5 ng/ml in only four patients (15%). Elevated antigen levels ranged from 2.7-18.0 ng/ml. All of these patients had advanced disease by either clinical or surgical staging systems. Four of twelve patients with inguinal metastasis had elevated SCC antigen levels. In two of these patients the inguinal nodes were abnormal to palpation. No association of the SCC level and the degree of tumor differentiation was observed. SCC antigen levels were increased slightly (2.7-4.5 ng/ml) in three of six patients with locally recurrent disease. In one patient with distant recurrence the SCC antigen was 15.3 ng/ml. In both primary and recurrent disease all elevated SCC antigen levels decreased with effective therapy. Vulvar cancer is primarily a local disease that is easily assessed by physical examination. An effective tumor marker in vulvar cancer would benefit only the rare patient with distant but not local disease.
