Again, another study.

Abstract


The aim of this study was to discover the clinical value of the tumour marker AMDL DR-70 in a group of patients with cancer of the tongue. Serum concentrations of AMDL DR-70 were estimated by enzyme linked immuno-sorbent assay in 52 patients with carcinoma of the tongue and compared with 40 controls and 42 patients with benign lesions in the tongue. Thirty-nine patients with carcinoma of the tongue had results above 6 mg/L (75%), compared with 3/40 (7%) in healthy controls and 4/42 (10%) in those with benign tumours. The concentration of AMDL DR-70 in serum correlated significantly with 3-year survival.

From the above, you can calculate the sensitivity and specificity.

Senstivity = 39 / 52 = 75%

Specificity for those having tumors 83%

for general screening, you would have 10% of all healthy people testing positive. That would be a HUGE number considering the incidence of cancer in the tounge is very low.
