[Postoperative prophylactic intravesical instillation of tetrahydropyranyl-adriamycin (THP) for superficial bladder cancer].
Intravesical instillation of tetrahydropyranyl-adriamycin (THP) was performed on 51 patients with superficial bladder cancer after transurethral resection (TUR) for prophylaxis of recurrence. The instillation was carried out with 20 mg of THP dissolved in 40 ml of distilled normal saline. Instillation was performed once 24 hours postoperatively, 9 times every 2 weeks, and 8 times every 4 weeks. These drugs were instilled for 30 to 60 minutes. The recurrence-free survival at 1, 2 and 3 years was 74.5%, 64.6% and 58.0%, respectively. Side effects of THP instillation were observed in only 4 cases (7.8%) as slight urinary frequency or micturition pain. Cases involving 5 or more tumors, or tumors measuring 3 cm or larger, more frequently demonstrated recurrence. The cases that did not respond to preoperative intravesical instillation of THP demonstrated a high frequency of recurrence. Intravesical instillation of THP as a prophylaxis against recurrence of superficial bladder cancer was effective in selected patients.
