Treatment of renal cell carcinoma with renal infarction, delayed nephrectomy, medroxyprogesterone, and xenogeneic immune RNA.

The authors have used xenogeneic immune ribonucleic acid (RNA) in the treatment of patients with renal cell carcinoma. This has been used in conjunction with renal artery embolization, delayed nephrectomy, and progestational therapy, using immune RNA derived from sheep cell lymphocytes immunized with patient's tumor. Four of 5 patients with Stage I disease had extremely large primary tumors. This group is alive with no evidence of disease at twelve to twenty-four months. There are no Stage II tumors in this group. One patient with Stage III tumor is alive at twenty-two months without evidence of disease. Three patients with metastases are stable at five to twenty-two months. Two patients have progressive disease at three and six months. This treatment has not been effective in patients with massive tumor burden. The results in the other groups are encouraging.
