[Clinico-morphological characteristics of transitional cell carcinoma of the prostate]

Transitional cell carcinoma was identified in 11 out of 600 autopsied cases of prostatic cancer (1.8%). Invasion into adjacent organs and tissues was recorded in 6 out of 11 cases, metastases--in 9 (bone lesions--5 cases). Most of the cases suffered poorly-differentiated transitional cell carcinoma (areas of undifferentiated small-cell tumor in some cases). Transitional cell carcinoma of the prostate is a highly malignant tumor, resistant to hormonal and radiation treatment.
