Complete resolution of multiple pulmonary metastases of renal cell carcinoma following intravenous drip infusion of r-interleukin 2: a case report.
A 68-year-old man with multiple pulmonary metastases from a right renal cell carcinoma was treated with alpha interferon, but there was no improvement. For this reason, alpha interferon was ceased, and daily monotherapy with recombinant interleukin-2 (1,000,000 units/day) was commenced. After 4 months, plain chest x-ray and chest CT revealed complete clearance of the pulmonary metastases. There were no side effects except general fatigue and slight fever. Immunological studies revealed elevation of the leukocyte count (lymphocytes, eosinophils) and enhancement natural killer activity. At 10 months after discontinuation of the drug, recurrence has not been observed. Our case indicates the potential value of interleukin-2 following treatment with alpha interferon.
