Cyfra 21-1: a serological help for detection of distant metastases in head and neck cancer.
Local and neck recurrences of squamous cell carcinoma of the head and neck (SCCHN) can mostly be detected early when the patient has regular follow-ups. Distant metastases though usually remain undiscovered until they produce clinical symptoms. Since Cyfra 21-1 correlates with the tumor size and stage in SCCHN, we looked for possible connections between Cyfra 21-1 increases and the development of distant metastases. The sera of 830 patients with SCCHN were tested for Cyfra 21-1. The levels were compared with the clinical run of the patients. When Cyfra 21-1 levels rose above the threshold of 3.3 ng/ml (71 out of 830) staging procedures were performed. Tumor growth was found in 50 out of 71 patients with elevated Cyfra levels (70.4%). Cyfra serum levels in those cases either represented development of distant metastases (27 out of 71), or local and neck recurrences. The results of this study show that Cyfra 21-1 is a suitable and helpful serological parameter for the follow-up of patients with SCCHN. In the event of an elevation of Cyfra 21-1 above the threshold during follow-up, we would recommend the performance of a thoracal CT-scan and abdominal omi ultrasound as staging procedures.
