[Immunotherapy of metastatic renal cell carcinoma in Germany. An assessment of the current status].
This survey was established to evaluate everyday use of interferon-alpha (IFN-alpha) and interleukin-2 (IL-2) in metastatic renal-cell carcinoma (mRCC). Of 186 centers (with 2200 patients per year) that responded, 182 support immunotherapy by using it themselves (147 centers) or by referring patients (35 centers). Effectiveness and tolerance are the main reasons for use. 133 centers use IL-2 subcutaneously, 64 by inhalation, 24 use it locally or intratumorally. Continuous intravenous IL-2 is used in 13 centers only. Most centers use subcutaneous combinations of IL-2 and IFN-alpha, either alone or with 5-fluorouracil and/or isotretinoin; IFN-alpha/Vinblastin combinations, IFN-alpha-monotherapy, and IL-2 s.c.-monotherapy are used with similar frequency. Average treatment duration is 3-6 months. Maintenance therapy is used in responding patients in 118 centers. Subcutaneous and local application of IL-2 is standard treatment for mRCC in Germany and subcutaneous IL-2 and IFN-alpha represents the most frequently used combination.
