Objectives. To evaluate the prognostic value of chromosomal aberrations in
muscle invasive bladder cancer, because they are of diagnostic and prognost
ic significance in superficial bladder cancer.
Methods. One hundred ninety patients, who underwent radical cystectomy beca
use of squamous cell carcinoma (SCC) of the urinary bladder in 94 cases and
transitional cell carcinoma (TCC) in 96 cases, were studied retrospectivel
y. Numerical aberrations of chromosomes 7, 9, and 17, p53 positivity, histo
logic stage and grade, histologic tumor type, lymph node status, and the pr
esence of bilharzial eggs were investigated as possible prognostic factors.
Results. Univariate analysis demonstrated the prognostic significance of al
l parameters analyzed, excluding chromosome 9, Multivariate analysis reveal
ed only T category (P = 0.01095266), lymph node involvement (P = 0.00054877
), and p53 positivity (P = 0.0316974) to be independent prognostic factors
in muscle invasive SCC and TCC.
Conclusions. Although chromosomal aberrations are associated with progressi
on-free survival, they are not independent prognostic factors and give the
clinician no additional information on patients with muscle invasive bladde
r cancer. UROLOGY 53: 1005-1010, 1999, (C) 1999, Elsevier Science Inc. All
