title: [Oral administration of 5-fluorouracil (5-FU) with intravesical chemotherapy as prophylaxis against recurrence of superficial bladder tumors].
abstract: The oral administration of 5-FU together with the intravesical instillation of carboquone and cytosine arabinoside was attempted in cases of superficial bladder tumor for the purpose of prophylaxis against postoperative recurrence. The recurrence rate in 25 patients treated by this intravesical chemotherapy and oral 5-FU administration was 9.1% after one year, 14.0% after two years and 27.8% at three to five years. The recurrence rate in 13 patients with intravesical chemotherapy alone was 8.7% after one year, 31.5% after two years and 58.9% at three to four years. The recurrence rate in six patients with oral 5-FU administration alone was 18.2% after one year, 41.6% after two years and 100% after three years. These results suggest that oral administration of 5-FU in combination with intravesical chemotherapy is useful as prophylaxis against recurrence of superficial bladder tumors.
