摘要

The authors propose that patients with low-grade papillary bladder tumors could be monitored safely, deferring therapy unless the recurrent tumors increased in size or number. Few patients (6.5%) had stage progression, and more (16%) developed recurrence with higher grade tumors; however, none progressed to muscle-invasive disease. Although this report confirms several recent reports that active surveillance of small papillary bladder tumors might be a reasonable strategy, reducing the burden of frequent transurethral resections, the study had 3 main weaknesses.
