Low compliance to guidelines in nonmuscle-invasive bladder carcinoma: A systematic review.

PURPOSE: This systematic review assessed compliance to guidelines for the management of nonmuscle-invasive bladder carcinoma (NMIBC).

METHODS

The PUBMED, Web of Science, Cochrane Library, and Scopus databases were searched in November 2019 in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis statement.

RESULTS

Fifteen studies incorporating a collective total of 10,575 NMIBC patients were eligible for inclusion in this systematic review. We found that the rates of compliance were 53.0% with a single immediate intravesical instillation in patients with presumed low or intermediate risk, 37.1% with intravesical bacillus Calmette-Guerin or chemotherapy in those with intermediate risk, 43.4% with performance of a second transurethral resection in high-risk patients, 32.5% with administration of adjuvant intravesical bacillus Calmette-Guerin in high-risk patients, 36.1% with radical cystectomy in highest-risk patients, and 82.2% with cystoscopy for follow-up.

CONCLUSIONS

Compliance with NMIBC guidelines remains low. Better guideline education and understanding holds the key to achieving high compliance. Strategies to improve guideline compliance at the physician level are urgently required.
