The following are multiple choice questions (with answers) about medical knowledge.   Cholecystectomy for GB polyps that are larger than 10 mm is generally recommended because of the high probability of neoplasm. In contrast, a follow-up strategy is preferred for GB polyps smaller than 10 mm. However, there are no treatment guidelines for polyps that grow in size during the follow-up period.STUDY: We retrospectively investigated 145 patients with GB polyps who underwent at least 1 ultrasonographic follow-up examination over an interval greater than 6 months, before cholecystectomy at Samsung medical center, South Korea, from 1994 to 2007. The growth rate was determined based on the change in size per time interval between 2 ultrasonographic examinations (mm/mo). The median age of the patients was 48 years (range: 25 to 75). One hundred twenty-five non-neoplastic polyps and 20 neoplastic polyps were found. Neoplastic polyps were more frequently found in patients older than 60 years, those with hypertension, a polyp size greater than 10 mm, and a rapid growth rate greater than 0.6 mm/mo. On multivariate analysis, however, the growth rate was not related to the neoplastic nature of a polyp, but older age (>60 y) and large size (>10 mm) were significantly associated with neoplastic polyps.   **Question:** Can the growth rate of a gallbladder polyp predict a neoplastic polyp?   (A) Yes   (B) No   (C) Maybe
