The primary objective of this study is to answer the question "Is it possible to inject the Combig-DC vaccine in a renal tumour without getting unacceptable side effects"? Patients newly diagnosed with metastatic renal cell carcinoma will get Combig-DC vaccinations at two occasions in a two weeks period (day 1 and day 14). After another two weeks the kidney will be eliminated. Adverse events will be registered, as well as changes in vital signs(heart rate, blood pressure and body temperature) and lab parameters. Immunologic response will be evaluated by measuring immunologic markers in blood and tumour tissue, and measuring the size of the metastases three months after nephrectomy.
