[Changes in carcinoembryonic antigen and tissue polypeptide antigen in monitoring the post-operative course of some tumor types]. / Il comportamento del CEA e del TPA nel monitoraggio del decorso post-operatorio di alcuni tipi di tumore.

The authors tested TPA in association with CEA in colon rectal, breast and stomach cancer. The results proved the reliability of TPA in these neoplasms and the correct use of TPA in association with CEA test in monitoring breast cancer. It's use proved to be typical screening test both for the high percentage of true positive and the lack of false negative.

[Association of ferritin with the CEA test in post-operative monitoring of colo-rectal, breast and stomach carcinomas]. / L'associazione della ferritina al CEA test nel monitoraggio post-operatorio dei carcinomi del colon-retto, della mammella e dello stomaco.

On the basis of more than 3,000 tests carried out on 1,561 patients suffering from suspected or certain malignant tumours, the authors established the necessity of CEA test in post-operative follow-ups, according to the plentiful literature regarding this matter. New tumoral markers led the authors to verify if it was useful to associate the ferritin to CEA test. From the results and the statistical data, they concluded that it was useful to associate the two markers only in negative CEA test when confronted with clinical suspected metastatic diffusion.
