ABSTRACT

Conclusion:

Our study is the largest case series on UC in Turkey . Due to the large number of patients, we believe that the results reflect the present status of the frequency and stage of UC variants and the gender and age of patients at diagnosis.

Results:

Between 2010 and 2015, 1355 biopsies from 1081 different patients were present with the diagnosis of UC. Totally, 676 patients with recurrence were excluded. Finally, 679 patients were included. When all patients were screened in terms of newly identified variants in the WHO 2004 classification system, 153 patients (22.6%) had UC variants, forming at least 10% of the biopsy specimen. We identified 15 UC variants: squamous differentiation, glandular differentiation, and small cell, micropapillary, sarcomatoid, lymphoepithelioma-like, nested, large nested, large cell neuroendocrine, plasmacytoid, pleomorphic, trophoblastic, rhabdoid, chordoid, and undifferentiated carcinomas.

Methods:

Patients with UC diagnosed in our pathology clinic between 2010 and 2015 were identified using an electronic database. They were re-examined according to the World Health Organization 2004 (WHO ) classification system, and the grade and stage of UC and concomitant UC variants were documented for each patient. In addition to these data, the age and gender of each patient were obtained from the electronic database.

Objective:

In our study, the age and gender of patients and the stage and grade of conventional bladder urothelial carcinoma (UC) and bladder UC variants were investigated.
