Muscle and small intestinal metastasis of renal cell carcinoma markedly responsive to interferon-alpha therapy: a case report.
Skeletal muscle and small intestine are rare sites of metastasis in renal cell carcinoma. Therefore very few reports of interferon-alpha (IFN-alpha) therapy exist for these types of metastasis. Here, a case of metastatic renal cell carcinoma to muscle and jejunum is reported. After IFN-alpha therapy for 9 weeks, muscle metastasis completely disappeared and intestinal lesions were markedly reduced. However, subsequent patient compliance for this therapy was poor, resulting in death after relapse of the RCC.
