title: Monitoring endoscopic treatment of superficial bladder carcinoma by postoperative urinary cytology.
abstract: Transurethral resection was the only modality of treatment in 39 patients with long-standing, recurrent, superficial bladder carcinoma. Postoperative urinary cytology was performed within 3 days of each endoscopy. Tumor recurrence was defined by the presence of a positive biopsy or visible papillary tumors on followup cystoscopic examination. Tumor recurred in 38 patients (97.4 per cent) and 1 patient (2.6 per cent) has remained free of disease 74 months following transient positive postoperative cytology. Among the 38 recurrences 15 (39.5 per cent) were positive, 3 (7.9 per cent) suspicious and 20 (52.6 per cent) negative at the postoperative cytological examination. The interval to recurrence did not differ significantly among the 3 groups. The failure of a negative postoperative cytology study to predict a durable response to treatment by transurethral resection reflects the polychronotopic nature of superficial bladder tumors in this select patient population and suggests the need for adjuvant therapy.
