| Popis: | Patients with T1G3 bladder cancer have a considerable risk for recurrence and/or progressive disease. Until now no consensus has been achieved on the optimal treatment. Within the Dutch South Eastern Bladder Cancer Study Group, 155 patients with a T1G3 bladder tumour were seen between 1983 and 1988. After review of histology, 121 could be evaluated and recurrence-free interval was studied with regard to prognostic factors. Prognostic factors such as sex, age, blood group, abnormalities on intravenous urography, pretreatment tumour configuration, number of tumours, number of locations involved in the bladder, voided urine cytology, results of random biopsies and mitotic index were evaluated, using a multivariate analysis with the Cox proportional hazard model. During the follow-up period, 70 (58%) patients had recurrent bladder cancer, and of these 30 (43%) had progression into invasive disease. Of the possible prognostic factors analysed, only multiplicity (P = 0.03) and the number of locations of the tumours (P = 0.03) were independent prognostic factors in relation to the risk of recurrence. The recurrence-free interval was influenced by the therapy. For T1G3 tumours, additional intravesical immunotherapy/chemotherapy or radiotherapy after transurethral resection (TUR) increased the recurrence-free interval significantly. Because most other parameters did not show additional prognostic value, the T1G3 tumours can be considered as homogeneous with regard to prognosis. Only multiplicity and the number of locations involved added to the prognostic significance of patients with these bladder tumours. In addition, it is advisable to give patients with T1G3 tumours additional treatment after the initial TUR. |
