“…14,15 While the risk of dysplasia increases with polyp size in FAP-associated FGPs, a study of 132 large (> 1-cm) sporadic FGPs with a median follow-up of 3.2 years reported a rate of dysplasia of 2.6 cases per 1,000-person years of follow-up and no carcinoma. 16 This study may have been limited by its short follow-up period, as reports of cancer with sporadic FGPs do exist. 15 In the rare cases of sporadic FGPs with carcinomas, most are small polyps with a mean size of 5.4 mm, suggesting that even polyp size may not predict malignancy risk.…”
