[A case study of metastatic renal cell carcinoma in lungs showing complete response to continuous subcutaneous injection of interferon alpha and gamma].
Previously, we reported a case of complete response (CR) of metastatic renal cell carcinoma with inhalant interferon-gamma. This inhalant therapy was considered effective against metastatic lung hilar tumors. On the other hand, metastatic tumors of the peripheral lung field tumor did not respond to the inhalation therapy. We report, a case of metastatic renal cell carcinoma in peripheral lungs showing complete response to continuous subcutaneous administration of interferon alpha and gamma. A 53-year-old woman was admitted to our hospital because of a large palpable mass in the left upper quadrant in March, 1994. Computerized tomographic (CT) scan disclosed a huge renal tumor. To reduce the tumor size, transarterial embolization, and subcutaneous administration of interferon-gamma were performed. In April 1994, the tumor was completely excised. In the post-operative course, multiple metastases were recognized in the lower peripheral lung field, subcutaneous administration of IFN-gamma and inhalation of IFN-gamma were begun, but the tumor size increased in October 1994. She underwent continuous subcutaneous administration of IFN-alpha and gamma. Three months later, the lung tumor disappeared. She has remained tumor-free as of October 1995. We concluded that this therapy may be effective against metastatic renal cell carcinoma in the lungs.
