Abstract

To evaluate the prognostic value of CCND1 polymorphism in superficial and invasive transitional cell cancer of the bladder. CCND1 polymorphism of blood DNA from patients with transitional cell cancer of the bladder was evaluated using the polymerase chain reaction-restriction fragment length polymorphism method. No statistically significant difference was found in the recurrence-free survival of patients with superficial (pTa-T1) transitional cell cancer after transurethral resection among different genotype groups (AA versus GG, P = 0.746; GA versus GG, P = 0.979). In patients with superficial bladder cancer, the occurrence of primary carcinoma in situ was significantly greater in patients with the AA genotype compared with those with the GA or GG genotypes (P = 0.006, chi-square test). No statistically significant difference was found in disease-specific survival after radical cystectomy among the different genotype subgroups (AA versus GG, P = 0.245; GA versus GG, P = 0.649). Although CCND1 polymorphism is not able to serve as a prognostic marker for bladder cancer, the CCND1 variant A allele may recessively increase the risk of carcinoma in situ incidence in patients with superficial bladder cancer.
