ABSTRACT
Context Despite the follow-up protocols developed in non–muscle-invasive bladder cancer patients, progression and recurrence could not be prevented.

Aims:

We aimed to investigate whether proteins such as OCT-4, CD47, p53, Ki-67, and Survivin, which increase in bladder cancer cells, can be used as prognostic markers for patients with non–muscle-invasive bladder cancer. Settings and

Design:

The study included a total of 89 patients with newly diagnosed non–muscle-invasive bladder cancer between January 2015 and December 2020. Materials and

Methods:

Levels of OCT-4, CD47, p53, K?-67, and Survivin proteins in cancer cells were determined with a semi-quantitative immunohistochemical experiment. Pathological data and survival rates were compared according to the staining rates. Statistical Analysis Used Data obtained in the study were analyzed statistically with SPSS 22.0 (SPSS, Chicago, IL, USA).

Results:

The mean age of the patients was 64.25 ± 9.91 years, and the median follow-up period was 55 months. Recurrence rate was determined to be 36% (n = 32), and the rate of progression at 40.4% (n = 36). The staining rates were stronger for each marker in the progression group and advanced-stage tumors (p < 0.001). The findings of the multivariate analysis carried out as part of the study showed that older age and higher tumor stage were independent risk factors for recurrence-free survival (HR = 1.048 and 7.074, respectively; P = 0.02). Also, higher tumor stages, diameters, and grades were associated with reduced progression-free survival (HR = 0.105, 0.395, 0.225, respectively; P < 0.05).

Conclusions:

Although immunohistochemical staining rates are promising, it is more appropriate to use tumor characteristics when assessing survival rate in patients with non–muscle-invasive bladder cancer.
