We conducted a prospectively randomized clinical trial to compare the efficacy and safety of subcutaneous interferon-α2a, subcutaneous interleukin-2 and intravenous 5-fluorouracil as home therapy against oral tamoxifen in 78 patients with progressive metastatic renal cell carcinoma. Treatment courses consisted of interferon-α2a 5 × 106 IU m−2day 1 weeks 1 + 4; days 1, 3, 5 weeks 2 + 3; 10 × 106 IU m−2days 1, 3, 5 weeks 5–8; interleukin-2 10 × 106 IU m−2twice daily days 3–5 weeks 1 + 4; 5 × 106 IU m−2days 1, 3, 5 weeks 2 + 3; and 5-fluorouracil 1000 mg m−2day 1 weeks 5–8. The tamoxifen group received tamoxifen 80 mg twice daily over 8 weeks. Among 41 patients treated with interleukin-2, interferon-α2a and 5-fluorouracil there were 7 complete (17.1%) and 9 partial responders (21.9%), with an overall objective response rate of 39.1% (95% CI, 24.2–55.5). An additional 15 patients (36.6%) were stable throughout therapy. The overall survival was 24 months (range 5–76+). In 37 patients receiving tamoxifen no objective remissions occurred. 13 patients (35.1%) had stable disease and 24 patients (64.9%) showed continued disease progression. The overall survival was 13 months (range 3–73+). In summary, this home-based therapy regimen of interferon-α2a, interleukin-2 and 5-fluorouracil demonstrated significant therapeutic efficacy in patients with progressive renal cell carcinoma when compared to hormonal therapy. © 2001 Cancer Research Campaign  http://www.bjcancer.com

A case of giant hydroureteronephrosis in a man is reported. Diagnostic evaluation included ultrasound, urethrocystoscopy and percutaneous puncture to assess the outline of the urinary tract and to locate a suspected ectopic ureteral orifice. Standard treatment usually consists of primary nephroureterectomy. A review of the literature with respect to etiology, diagnostic criteria and treatment modalities is presented.

Xanthogranulomatous pyelonephritis, a special form of pyonephrosis, is hard to differentiate from other inflammatory or tumourous changes of the kidney. This is due to manifold clinical symptoms and uncharacteristic X-ray findings. The diagnosis is made histologically. The disease was observed in four female patients ages 11 to 53 years. Nephrectomy leads to cure in diffuse forms of the disease. In localised forms organ preserving operations with partial renal resections are sufficient.
