Abstract
Objective: The aim of this study is to determine whether there is a genetic predisposition in young patients
with transitional cell carcinoma (TCC) of the bladder.
Material And Methods: Data were collected from a total of 652 patients who underwent transurethral
resection of bladder tumor (TUR-BT) between January 2010 and January 2021. Seven patients under the age
of 40, non-smokers, and without occupational predisposing factors to urinary tract TCC were included in the
study. Age, body mass index (BMI), sex, occupation, and five-year follow-up were collected retrospectively.
A total of 403 cancer-related genes were analyzed from the patients’ blood samples. The Clinical Exome
Sequencing test was used to identify genetic mutations.
Results: Six of the patients were male and one patient was female. The mean age and BMI were 31.42 ± 2.12
(22-39) years and 21.72 ± 33.14 (22-27.7) kg/m2, respectively. None of the patients had a first-degree relative
with urinary tract TCC. Of all the patients, only one patient had a deletion of exons 1 to 17 in the breakpoint
cluster region gene.
Conclusion: Genetic predisposing factors in young bladder TCC have not been clearly identified. Although
our study included a limited number of patients, our results showed no genetic predisposition in young
patients with bladder TCC without family history of bladder cancer. To evaluate the exact relationship,
prospective randomised controlled trials with larger numbers of patients are needed.
