A chest X-ray tomography revealed a metastatic shadow in the left lung of a 56-year-old man with pathologically established right renal cell carcinoma. The shadow was found to be regressed to a fibrous lesion on the 18th day after radical nephrectomy. Because of non-A, non-B, hepatitis, the anticancer treatment with alpha-interferon and 1-(2-tetrahydrofuryl-5-fluorouracil) was started 40 days after the nephrectomy. At that time, only a fibrous lesion was noted at the site of lung metastatic shadow. At present, the patient remains free of disease for 21 months after nephrectomy.
