| Popis: | To estimate the extent of local tumor spread is a main goal in the diagnosis of prostate cancer (PC). The value of this criterion is that its clinical stage plays a key role in choosing a treatment policy. Overestimation of the clinical stage of cancer leads to the fact that specialists refuse radical and its underestimation gives rise to its recurrence. Our trial defined criteria for the diagnostic efficiency of magnetic resonance imaging (MRI) in 150 PC patients who had undergone radical prostatectomy. The findings were as follows: the diagnostic sensitivity of the method in determining the spread of the cancer beyond the organ was 76.8 %; its diagnostic specificity and accuracy were 80.2 and 78.7 %, respectively. The positive predictive value in detecting the extra-organ spread of the tumor was equal to 76.8 %; the negative predictive value was 80.2 %. A prognostic classification of a risk for locally advanced PS has been developed using the independent clinical and MRI signs found. |
