Klatte et al identified prognostic factors for a patient with a clear cell renal cell carcinoma, including cytogenetic factors. This was used to develop a nomogram. The authors are from the University of California at Los Angeles.
Parameters:
(1) T stage
(2) N stage
(3) M stage
(4) Fuhrman grade
(5) loss of 9p

total score =
= SUM(points for all 5 parameters)
Interpretation:
• minimum score: 0
• maximum score: around 330
• The higher the score the worse the prognosis.

Other cytogenetic findings associated with a better prognosis (not significant in multivariate analysis):
(1) deletion of 3p
(2) loss of Y chromosome (in metastatic disease)
Other cytogenetic findings associated with a worse prognosis (not significant in multivariate analysis):
(1) loss of 4p
(2) loss of 14q
Purpose: To evaluate a patient with a clear cell renal cell carcinoma using the prognostic factors of Klatte et al.
