Factors influencing the prognosis in bladder cancer

In the categories T1, T2 and T3NxM0 bladder cancer, diameter not exceeding 5 cm, the treatment in the Rotterdam Radio-Therapy Institute consists of interstitial irradiation with needles containing radioactive material. The results of treatment and the role of additional external irradiation are discussed. Category T3NxM0 tumors diameter exceeding 5 cm are treated by external irradiation followed by cystectomy; the results are presented here. Factors influencing prognosis appeared to be degree of differentiation, number of transurethral resections (TURs) prior to definitive treatment, intravenous pyelography (IVP), vascular invasion, T category after preoperative irradiation, and postsurgical histopathologically-assessed T category (pT).
