title: [The value of gastrointestinal antigens in the monitoring of patients with malignant head neoplasms].
abstract: The authors present the results of examinations of test on the sensitivity of biochemical tumor marker (Ca 19-9) in a group of 35 patients with head malignant tumors. The sensitivity (SE) of Ca 19-9 was 22.9% in preliminary study. The values of Ca 19-9 changed from 22.9% to 25.9% in monitoring of tumors. Positive predictive value (PV+) and specify (SP) were 100% in preliminary study and in monitoring. Negative predictive value (PV-) was 50.9% in preliminary study and 51.6% in monitoring. In 25 patients we observed changes in examined parameters: SE--35%, SP--100%, PV(+)--100%, PV(-)--42.1% in monitoring. Our study indicates that serum levels of Ca 19-9 were higher in patients with head tumors than in control group. The surgical treatment of tumors didn't change the values of Ca 19-9.
