摘要

Purpose

To review, evaluate and summarize data from the literature presenting the risk of developing gallbladder cancer in patients with PSC and gallbladder polyps.

Methods

The systematic review was performed according to PRISMA recommendations and registered in the PROSPERO database. The PubMed, ScienceDirect, Web of Science, Biomed Central and EBSCOhost databases were used. Studies analysing patients with PSC and gallbladder polyps, their association with malignancy and outcomes were included.

Results

Five retrospective studies and one case-control study with a total of 3415 patients diagnosed with PSC were included. Radiological examination of these 3324 patients with PSC revealed 207 (6.2%) gallbladder polyps, of which 34 (16.4%) were identified as gallbladder mass lesions. Of available histology results, 116 (34%) had gallbladder polyps. Out of these 116 patients with gallbladder polyps, gallbladder carcinoma (GBC) was found in 48 (41.4%) patients. The mean size of gallbladder polyps with adenocarcinoma ranged from 2.1 cm to 2.4 cm, whereas benign polyps ranged from 0.6 cm to 1.5 cm.

Conclusion

Gallbladder polyps with malignant changes are often observed in patients diagnosed with PSC. This supports international recommendations that cholecystectomy should be performed regardless of gallbladder polyp’s size in PSC patients.
