title: [Urologic tumors in Germany. Initial data of 56,013 cases from clinical cancer registers].
abstract: Since 1985 a special work group involved in the coordination of hospital cancer registries in Germany (AKKK) has been collecting, storing and analysing data on tumour patients, received from cancer centres, oncological departments and specialised practices. The documentation of tumour patients is based, among other things, on information concerning localisation, histological findings and tumour spread. The data are stored in a central database administered by the work group. At present it contains data on approximately 500,000 oncological patients. In the period from 1987 to 1992, 56,013 initial entries were made concerning patients with urological tumours. Of these cases, tumours of the kidney (n = 11,424) constituted 20.4%. In 94.6% of the cases, histological investigation revealed a renal cell carcinoma-pT1: 5.8%; pT2: 53.6%, pT3: 37.2% and pT4: 3.4%. Tumours of the urinary bladder (n = 16,246) constituted 29.0% of all urological tumours. In 93.8% of the cases a transitional cell carcinoma was detected-pTis: 1.0%; pTa: 36.9%; pT1: 29.6%; pT2: 16.9%; pT3: 11.4%; pT4: 4.4%. Transitional cell carcinomas of the ureter or of the collecting system (n = 1,846) constituted 3.3% of the cases. The proportion of testicular tumours (n = 6,594) amounted to 11.8%; 53.6% of these germ-cell tumours (n = 6,281) were seminomas and 46.6% were non-seminomas. In all, 66.3% of the cases were lymph-node negative. Tumours of the prostate (n = 19,903) constituted 35.5% of the cases. In the period from 1987 to 1992, the proportion of lymph-node-positive prostate carcinomas decreased from 39.8% to 16.2%. The detailed analysis of these data shows how the hospital cancer registries can support the discussion regarding diagnosis and therapy of urological tumours.
