[A case of pulmonary metastasis from renal cell carcinoma in which complete remission was achieved by interferon therapy (r-IFN-alpha A, Ro 22-8181)].
A case of pulmonary metastasis from renal cell carcinoma in which complete remission was achieved using interferon therapy is herein reported. A 54-year-old male underwent left nephrectomy following diagnosis of left renal cancer. Radiotherapy and hormonal therapy were performed postoperatively. Solitary pulmonary metastasis was found in the right lobe 4 months after surgery. The interferon (recombinant human leukocyte A interferon, rIFN-alpha A, Ro 22-8181) was initially administered i.m. at a dose of 3 X 10(6) units per injection every day. Marked response was observed one month after starting the interferon therapy (total: 183 X 10(6) U) and complete disappearance of the tumor was obtained 2 months after commencement of therapy (total: 345 X 10(6) U). The interferon was later injected at a dose of 6 X 10(6) U., 3 times a week because of general fatigue. The duration of complete response has lasted 8 months.
