Extraordinarily elevated serum levels of CA 19-9 and rapid decrease after successful therapy: a case report and review of literature.

چکیده
Carbohydrate antigen 19-9 is most valuable as a serum marker for pancreatic and biliary cancer, but increased concentrations occur in several other gastrointestinal malignancies. A carbohydrate antigen 19-9 value of >1,000 U/ml usually indicates a digestive cancer and has been reported to have a specificity greater than 99% for pancreatic cancer; nevertheless, false-positive results owing to benign diseases such as pancreatitis or liver cirrhosis have been noted. We present a patient with cholelithiasis and choledocholithiasis with acute cholangitis who had very high serum levels of carbohydrate antigen 19-9 (9586 IU/ml). The rapid decrease in carbohydrate antigen 19-9 after successful treatment was as interesting as the pretreatment high serum level of carbohydrate antigen 19-9.

Florid Adnexal Polypoid Endometriosis Associated with Very High Serum Ca - 125 Levels Mimicking Ovarian Malignancy
We report a case of florid polypoid endometriosis presenting with advanced bulky disease in pelvis with serum CA – 125 levels of 7844U/ml. The extent of tumor, CT scan findings, elevated serum CA – 125 levels were suggestive of ovarian malignancy. Histopathology demonstrated endometrial glands and stroma.

متن کاملGiant hydronephrosis due to a ureteral stone, and elevated serum levels of CA 19-9.
CA 19-9 is a widely used tumor marker. However, an elevation in serum CA 19-9 can occur in some patients with benign disorders such as cholecystolithiasis in the absence of tumor. We treated a case of acquired ureteral stone-induced giant hydronephrosis with markedly elevated serum CA 19-9 values. After nephrectomy, the serum CA 19-9 level returned to normal. No malignant cells were found in th...
