Carcinoma of the Urinary Bladder Treated by Interstitial Radium Implant
Six hundred and six patients with carcinoma of the bladder category T1, T2 and T3 not exceeding five centimetres in diameter were treated by radium implant at the Rotterdam Radiotherapy Institute. As a rule, preoperative irradiation to the category T2 and T3 lesions consisting of 3 × 350 rads is given. The preoperative irradiation does not significantly influence the prognosis in category T1 and T2 lesions but it completely prevents scar implants. In the T3 lesions it improves prognosis and also reduces the incidence of distant metastases in addition to completely preventing scar implants.
