[A case of CA19-9 producing transitional cell carcinoma of the ureter].
We report a case of CA19-9 producing urothelial carcinoma of the right ureter. A 61-year-old male patient who had an extremely high value of serum CA19-9 (1,185 U/ml) with right hydronephrosis was referred to us. Magnetic resonance urography and retrograde ureterography revealed a long irregular filling defect in the right distal ureter. Under the diagnosis of right ureteral tumor, we performed right total nephroureterectomy and pelvic lymphadenectomy. The tumor was histologically diagnosed as grade 1 transitional cell carcinoma and pelvic lymphnodes were positive (pT1N2M0). The tumor cells showed positive immunostaining for CA19-9. The serum CA19-9 level was normalized after the operation and successive adjuvant chemotherapy (M-VAC 2 course). No recurrence was found for 15 months after operation. In this case, the serum CA19-9 level was useful as a tumor marker.
