全身化学療法が奏効したCA19-9産生尿管移行上皮癌の1例

Abstract

We report a case of CA19-9 producing transitional cell carcinoma of the right ureter effectively responsive to combination chemotherapy (methotrexate, vinblastine, doxorubicin and cisplatin (M-VAC) regimen) in a 53-year-old woman. The maximum level of serum CA19-9 showed 3, 000 U/ml and clinical staging of the tumor was T4 N3 M0. Marked regression of the tumor was identified by computed tomographic scan and the level of serum CA19-9 returned to the normal range after 3 courses of M-VAC therapy. Right total nephro-ureterectomy and partial cystectomy was done and the surgical specimen revealed no viable tumors. She is alive without evidence of local recurrence or metastasis at 6 months after resection. The serum CA19-9 level was useful for monitoring the clinical course.
