[Superficial cancer of the bladder: which controls should follow and for how long the free of tumor patients?].
OBJECTIVE
To answer the following question: what monitoring and for how long should be maintained in patients with Ta-T1 vesical neoplasia and no tumoral relapse?


METHODS
Analysis of relapse probabilities in 123 patients with Ta-T1G1G2G3 primary tumours who had not relapsed for at least three years of follow up after transurethral resection. All patients were treated between January 1976 and December 1986; they all have follow-up potential of over 10 years. Mean follow-up 8.1 years, minimum 4 years, maximum 18 years.


RESULTS
Probabilities of relapse at 3 to 5 years, 6 to 10 years, 11 to 18 years are 18%%, 24% and 13%, respectively. Relapses were superficial in 38 cases (90%), infiltrant in 4 (10%) G1 in 21 (50%), G2 in 12 (29%), G3 in 9 (9%), single in 33 (79%), multiple in 9 (21%), under 2 cm in 35 (83%), over 2 cm in 7 (17%).


CONCLUSIONS
Epidemiologically, individuals with a background of surface vesical tumour have a much higher risk of relapse than the Spanish normal population and therefore they should be monitored for life. Relapses are usually superficial, low grade, single and small in size. Cystoscopy is the monitoring technique offering more possibilities for detection.
