DIAGNOSIS AND STAGING OF BLADDER CANCER

Urinary bladder cancer is a fairly common pathology in the structure of cancer morbidity, both in the world and in the Russian Federation, especially in elderly patients. As is well known, the 5-year survival and disease-free survival rates directly correlate with the stage of the tumor process, which determines the significance of an adequate assessment of the distribution of tumors for planning treatment approach. This article provides an overview of scientific studies on imaging techniques that are used for preoperatively staging of urinary bladder cancer. Currently, the most interesting is multiparametric-MRI, which has a number of advantages over other imaging methods including: non-invasiveness, high tissue and spatial visualization and the absence of ionizing radiation. The appearance of this method contributed to an increase in diagnostic effectiveness in assessing the distribution of urinary bladder cancer. However, there are a number of unresolved issues related to errors in interpreting the depth of invasion and evaluation of regional lymphatic outflow, which require detailed study and analysis.
