Current status of transcatheter management of neoplasms.
Transcatheter arterial infusion and arterial embolization are employed in the treatment of various neoplasms. In patients with carcinoma of the colon metastatic to the liver, the hepatic arterial infusion (HAI) of floxuridine and Mitomycin produced a 55% partial response and a 12% complete response, as well as an improved median survival of 18 months. In metastatic breast carcinoma, a 30% response was achieved. In some cases, proximal embolization of aberrant hepatic arteries was performed to redistribute the hepatic flow to a single vessel to assist infusion of the entire liver using a single catheter. Devascularization by hepatic artery embolization has also been used to treat hepatic neoplasms. Arterial occlusion of renal carcinoma, followed after four to seven days by nephrectomy and hormonal therapy, produced a 36% response rate in 49 patients with distant metastases. In 14 patients with osteosarcoma treated with cis-diaminedichloroplatinum (CDDP) arterial infusion, a 57% response rate was achieved. Benign bone tumors were treated with arterial occlusion with a 60% response rate. Tumors of the pelvis were managed by bilateral internal iliac artery infusion using CDDP. In 21 patients with recurrent bladder carcinoma, control of pain and hematuria and prolonged survival were achieved.
