The value of tumor tissue penetration into the renal veins and lymph nodes as anatomical classification and kidney tumor prognostic parameters.
Renal vein invastion (great renal veins and vena cava) does not give such a bad prognosis in renal neoplasia. We could even say that this fact is relatively irrelevant for the prognosis but nevertheless signifies an extracapsular stage of renal tumor with the destiny under question. Lymph node invasion cannot be satisfactorily classified only as N+ and NO as proposed by UICC. The author proposed the classification from N1 to N4 as we must distinguish some stages in lymph node invasion of a renal neoplasm. The very distinct difference is if we have a case with invasion of only some nodes (1--5 in number) or we have a very large invasion making a pack around the great vessels (cava and aorta). In the first group we can have a fairly good prognosis (37% surviving 5 years or more), but in the second group the survival is very low (2%).
