[Tumor markers in malignant anorectal pathology].

The Authors note the limits and the more rational directions of using the several tumour markers that they utilized in the study of the neoplastic pathology of the anus-rectum. They particularly point out the benefit as "dynamic indices" of variation of the tumor mass during the neoplasm's progress and treatment. For these neoplasies any new marker offers advantages of diagnostic accuracy and a greater specificity more CEA. Nevertheless other markers used appear interesting as biochemical parameters for tumour growth. The study and the tumour marker's development supported, in recent years, the introduction of new diagnostic methods that include the utilization of monoclonal localization of the tumour mass.
