Impact of type 2 diabetes on adenoma detection in screening colonoscopies performed in disparate populations

Table 7 Comparison of colonic lesions (polyps and colorectal cancer) in type 2 diabetes mellitus and prediabetics mellitus (hemoglobin A1c ≥ 5.7%, < 6.5%) patients at an urban public hospital, n (%)

Variables	T2DM n = 529	Pre-DM n = 542	P value
All colonic neoplastic lesions	195 (36.9)	173 (31.9)	0.0959
Location of neoplastic lesions			0.3534
Left-sided only	56 (10.6)	54 (10.0)
Right-sided only	105 (19.8)	92 (17.0)
Both	34 (6.4)	27 (5.0)
Adenomas (not serrated or CRC)	186 (35.2)	168 (31.0)	0.1515
Sessile serrated adenoma	6 (1.1)	3 (0.6)	0.3324
Advanced adenoma (> 1 cm, villous, high grade dysplasia, not including CRC)	29 (5.5)	22 (4.1)	0.3137
High risk adenoma (> 3 adenomas and/or advanced adenoma)	45 (8.5)	39 (7.2)	0.4321
CRC	3 (0.6)	2 (0.4)	0.6858
Hyperplastic polyp only (no additional colonic neoplasia)	66 (12.5)	68 (12.5)	1.0000

CRC: Colorectal cancer; T2DM: Type 2 diabetes mellitus; Pre-DM: Prediabetics.
