CYFRA 21-1 as a tumor marker for squamous cell carcinoma of the esophagus.
This study assessed the clinical value of CYFRA 21-1 in comparison with squamous cell carcinoma antigen (SCC-Ag), carcinoembryonic antigen (CEA), and carbohydrate antigen 19-9 (CA19-9) in patients with esophageal squamous cell carcinoma. In 112 primary cancer patients, the diagnostic sensitivity of CYFRA 21-1 (33.9%) was superior to SCC-Ag (28.6%), CEA (12.5%), and CA19-9 (6.3%). Levels of CYFRA 21-1 were closely correlated with TNM stage and wee below the cutoff value in all 21 patients with stage I disease. All 38 patients with a CYFRA 21-1 level over the cutoff value among the 80 patients who underwent esophagectomy had lymph node metastases (pN1). A correlation was found between CYFRA 21-1 levels and clinical response in serial measurements of 21 patients who received chemotherapy or chemo radiotherapy. Our findings suggest that CYFRA 21-1 is not useful for diagnosis, but that it is valuable for monitoring the efficacy of therapy.
