Abstract
Experimental pancreatic carcinoma induced in Golden Syrian Hamsters by subcutaneous injections of N-nitrosobis-(2-oxopropyl) amine (BOP) was studied during the different phases of its development by determination of serum CA 19-9 levels and tissue labeling with CA 19-9 TM. Significant differences were observed in the CA 19-9 values between the controls and animals with carcinoma (p < 0.01) and between the latter and animals with cystic or cystic papillary lesions (p < 0.01). Distribution of the deposits of CA 19-9 TM was different in the initial tumoral lesions and in the longer-developed tumors. An important correlation was observed between tissue deposits and serum levels of this tumor marker.
