Cancer vesicae urinaria is the most common urologic cancer after cancer prostate. The incidence is increasing, and in 2001 1099 new cases were reported in Norway.
Cigarette smoking is the largest known risk factor, and is responsible for 50-66 % of the cases.
When working with this investigation, I read through 134 patient files. These patients have all been treated for cancer vesicae urinaria by the same urologist at Ringerike Hospital between 1994 and 2004. I collected data about the patients age, symptoms, cancer histology and WHO-grading and smoking status and made diagrams showing different connections.
My results showed that 60 % of the men and 55 % of the women were over 70 years by the time of diagnosis. In 65 % of the cases the initial symptom was hematuri. All the patients had transitional cell carcinoma and 84 % of the patients had a superficial cancer type (Tis, Ta and T1). 62 % of the patients were only treated with TUR-B and 16 % of the patients were also treated with BCG. 70 % of the male patients and 45 % of the female patients were smokers, and the distribution in histology and grading were the same as for the non-smokers.
My results are based on only 134 patients, so it is difficult to draw conclusions. When that said, my results are in line with results from earlier studies on the subject, and therefore it could be possible to apply these diagrams on larger patient materials.
