Elevated serum CA-125 levels in patients with nephrotic syndrome-induced ascites.

CA-125 is a sensitive, but not a specific, tumour marker especially used in the diagnosis and follow-up of ovarian cancer. Because of the elevated levels of CA-125 encountered during the etiological investigation of nephrotic syndrome (NS) a clinical study was designed to investigate the probable relationship between elevated CA-125 levels in patients with NS, with and without ascites. Twenty-four patients with NS due to non-tumoural pathologies, aged 24 to 56 (15 females and 9 males), were investigated. We detected elevated levels of serum CA-125 (275.92 +/- 154.71 U/mL) in 14 (70%) NS patients with ascites (p < 0.05). In the other 10 NS patients without ascites (Group 2) and in the control group, consisting of 52 age and sex-matched healthy volunteers, the serum CA-125 levels were found to be 13.60 +/- 5.12 U/mL and 8.50 +/- 5.02 U/mL, respectively (p > 0.05). There was no statistically significant difference between the control group and the patients without serosal fluids (p > 0.05). We concluded that serum CA-125 levels were elevated in NS patients with ultrasonographically detected ascites in the absence of an ovarian tumour or other diseases known to increase the levels of CA-125.

Synchronous primary malignant neoplasms of colon and bladder.

Extracolonic and synchronous malignancies are rare in colorectal carcinomas. We report a 68-year-old man with complaints of rectal bleeding and hematuria. Endoscopic biopsies revealed synchronous adenocarcinoma of the colon and transitional cell carcinoma of the bladder. The patient was started on chemotherapy, and is alive (with disease) nine months later.

The importance of serum and ascites fluid alpha-fetoprotein, carcinoembryonic antigen, CA 19-9, and CA 15-3 levels in differential diagnosis of ascites etiology.

BACKGROUND/AIMS: Clinical usage of tumor markers is being limited due to low specificity. Elevated plasma levels of tumor markers may be seen in diseases other than malignancy, i.e., kidney, liver or circulatory disturbances. METHODOLOGY: In our study, we studied serum and ascites fluid alpha-fetoprotein, carcinoembryonic antigen, CA 19-9, CA 15-3 levels in patients with chronic liver disease, spontaneous bacterial peritonitis, malignancy, tuberculous and congestive heart failure in a total of 76 patients. RESULTS: The sensitivity and specificity for ascites fluid alpha-fetoprotein levels were 28.5% and 100%, for serum alpha-fetoprotein levels 28.5% and 98.1%, for ascites fluid carcinoembryonic antigen levels 38.0% and 98.1%, for serum carcinoembryonic antigen levels 57.1% and 90.0%, for ascites fluid CA 19-9 levels 19.0% and 94.5%, for serum CA 19-9 levels 33.3% and 21.8%, for ascites fluid CA 15-3 levels 28.5% and 92.7%, and for serum CA 15-3 levels 47.6% and 81.8%, respectively. CONCLUSIONS: In conclusion, the sensitivity of serum and ascites fluid tumor markers was found to be low. High specificity may be due to low number of study participants. Serum and ascites fluid tumor markers are not found to be useful in the differential diagnosis of ascites etiology.
