[Study of large cross sections of infiltrating renal cell carcinoma (pT3) and long-term observation (more than 4 years)].
In a series of 59 consecutive renal cell carcinomas (pT3) cross sections were performed and grading was reevaluated on a cytological basis as described by Thoenes. Follow-up was at least 4 years. Only 20.3% of all tumors revealed monoform grading (92 resp. 93), while 79.9% consisted of more than one grading (G1+G2, G2+G3: 45.8%; G1+G2+G3: 33.9%). Prognosis in this series depended highly significantly (p less than 0.002) on the percentage of G3-area of the vital tumor (NED greater than 4 ys.: 11.4%; DOD less than 2 ys.: 51.6%). It is concluded that measuring different G-areas in cross section of renal cell carcinomas raise considerably prognostic value of histopathology.
