Combination of arterial infusion chemotherapy and embolization for the treatment of giant carcinoma of kidney in 32 cases / 中国微创外科杂志

ABSTRACT

Objective To explore the efficacy of arterial infusion chemotherapy combined with embolization for the treatment of giant carcinoma of the kidney.Methods Arterial infusion chemotherapy combined with embolization was performed through the renal artery in 32 cases of giant carcinoma of the kidney from April 1990 to April 2003.The chemotherapeutic agents were epirubicin(30~40 mg),mitomycin(20~30 mg),and 5-FU(500 mg).The embolization was conducted with anhydrous alcohol,sodium morrhuate,and lipiodol plus gelatin sponge.Results The arterial infusion and embolization was successfully administered in all the 32 cases.Surgical resection was accomplished in 8 cases 1~3 months after the embolization,and little or no blood supply to the tumor was seen during the surgery.Pathological findings revealed marked necrosis of tumor cells with inflammatory cell infiltration around and fibrous proliferation as well as capillary embolization.The total response rate(CR+PR) was 87.5%(28/32) and the tumor decreased in size in 90.6% of the cases(29/32).The survival rates at 6 months,1-,2-,and 3-year were 78.1%(25/32),68.8%(22/32),46.9%(15/32),and 31.2%(10/32),respectively.The mean survival time was 41.5 months,with the longest time of 84 months.Conclusions Combination of infusion chemotherapy and embolization through the renal artery for the treatment of giant carcinoma of the kidney offers good clinical effects.
