Patterns of initial transitional cell recurrence in patients after cystectomy.
OBJECTIVE
We characterized initial relapse patterns in patients who underwent cystectomy for transitional cell carcinoma of the bladder at our institution.


METHODS
Between June 1995 and December 2001 a total of 417 patients underwent radical cystectomy for transitional cell carcinoma. Of the 399 patients treated with orthotopic diversion or incontinent cutaneous diversion, recurrent TCC developed in 86 (21.6%). We retrospectively examined this population to determine if any perioperative variables influenced the first site of disease recurrence.


RESULTS
Of the 86 patients in whom metastatic disease developed after cystectomy, the mean followup was 22.1 months. Mean time to disease recurrence was 15.1 months. Recurrence was most commonly initially in the pelvis (30.2%). Other common sites of first recurrence included the viscera (26.7%), the retroperitoneum (16.3%) and the skeletal system (16.3%). The site of first recurrence did not correlate significantly with gender, age, diversion type, pathological stage, nodal status, prostatic involvement or the presence of a positive surgical margin. Lymphovascular invasion was more prevalent in the pelvic recurrence group (62%) than in the retroperitoneal (36%), visceral (22%) or skeletal metastases (29%) groups (p = 0.03).


CONCLUSIONS
While the pelvis is the most common site of disease recurrence following radical cystectomy, TCC of the bladder recurs in an unpredictable pattern and aggressive surveillance is indicated. Patients with local pelvic recurrence had a higher percentage of lymphovascular invasion on cystectomy than the other recurrence site groups.
