ABSTRACT
Objective: To study the recurrence rate of superficial bladder tumors at Cairo university hospitals. Patients and Methods: Sixty-six patients with superficial transitional cell carcinoma who were treated by either Nd: YAG laser therapy (16 patients) or transurethral resection (50 patients) were followed for a mean of 5.5 years. Results: Local tumor recurrence at the same site of the original tumor occurred in 39of patients while remote recurrence occurred in 33of patients. The total recurrence rate was 59. Tumor progression to invasive carcinoma occurred in 7 patients (11); and 3 patients (4.5) died of disease-related causes. Conclusion: The treatment of superficial TCC may be done by relatively minor endoscopic procedures; but the disease itself is a serious condition that merits close long-term follow-up
