Renal Cell Carcinoma is the third most common malignoma in urology. Only little is known about the etiology and risk factors; the age peak lies at 60 and twice as many men than women are affected. The clinical picture presents with a wide spectrum. Over one third of all tumours are detected accidentally by ultrasound or computed tomography in asymptomatic patients. Most common symptoms are hematuria and flank pain, the classical trials including in addition a palpable mass is rare and by mo means an early symptom. Paraneoplastic syndromes include unspecific (increased blood sedimentation rate, weight loss, fever) and endocrine symptoms (hypertension, polyglobulia, hypercalcemia). Diagnosis is based on imaging procedures. By means of sonography renal cysts may be separated from solid, space-occupying tumors. For the latter CT plays a decisive role for staging, therapeutic planning and prognosis. Further radiologic investigations (angiography, MRI) are indicated only in special situations. Rarely a biopsy is necessary for the distinction between renal cell carcinoma and metastases of other primary tumors. The only curative treatment of localized carcinoma is radical nephrectomy. Partial resection is indicated in cases of a single kidney, bilateral tumors and possibly also for tumors smaller than 4 cm in diameter. Radiotherapy is only initiated for palliation of painful skeletal metastases. In case of distant metastases--mainly pulmonary--nephrectomy should only be performed if systemic treatment is planned or if local complaints (pain, hematuria leading to anemia) exist. Chemotherapeutic drugs have no influence on survival. The effect of gestagens on life quality is questionable. Adoptive immunotherapy with cytokines (Interferon-alpha, interleukin-2) appears most promising. These substances, however, not yet been introduced into routine therapy should only be used in prospective studies. Furthermore, renal cell carcinoma is a potential candidate for gene therapy. After tumor nephrectomy follow-up investigations should be performed twice a year, because of the possibility of curative surgical treatment of late solid metastases. Prognosis of tumors restricted to the organ is good. Five year survival after operation is about 90%. However, is distant metastases exist already at the time of diagnosis 5 year survival drops to less than 10%.

A 59-year-old man presented with a 2-month history of left flank pain and a possibility of gross hematuria. Left renal cell carcinoma stage II was diagnosed and radical left nephrectomy was performed. Twenty-two months postoperatively, lung metastases were demonstrated and 6 x 10(6) units of alpha-interferon (IFN-alpha) were administered for 9 months, only to keep the sizes of the metastases unchanged. Thirty-four months after the operation, liver metastases and bone metastasis in the left sacroiliac joint were revealed. The combination cytokine therapy was performed with 1.4 x 10(6) U of interleukin-2 (IL-2) and 3 x 10(6) U of IFN-alpha for 16 weeks, and the left sacroiliac joint metastasis was treated with radiation therapy of 4 Gy per day for 7 days. Six months after the 16 weeks of immunotherapy, computed tomography and bone scintigraphy revealed that the metastases of the lung, liver and bone substantially disappeared and this complete response is still kept after 16 months.
