    Abstract:
    The concentrations of pregnancy protein 1 (SP1), placental-specific tissue protein 10 (PP10), placental-specific tissue protein 12 (PP12) and alpha1-Fetoprotein (AFP) were analyzed in serum samples of 83 patients with bronchial carcinoma at stages II-IV Protein levels were determined by means of single radial immunodiffusion, rocket immuno-electrophoresis, radioimmunoassay and enzyme- immunoassay. PP12 and AFP serum concentrations were significantly increased in the cancer group compared with the control group. PP12 (control group: x=54.08 microg/l; s=61. 70; tumor group: x = 122.52 microg/l; s = 131.16); AFP (control group: x=3.05 microg/l; s=3. 76; tumor group: x = 8.29 microg/l; s = 17.75). SPI was found in only 22 cases of the tumor group. PP10 (control group: x = 2.25 microg/l; s = 0.866; tumor group: x = 2.503 microg/l; s=1.508). Given that at least two of the tested parameters were determined to be in the pathological range, the sensitivity amounted to 0.64 and the specificity to 0.92.
