Basic characteristics of patients with postcolonoscopy colorectal cancers (PCCRCs) at the time of diagnosis versus those with prevalent CRCs
| PCCRC (n=147) | Prevalent CRC (n=4960) | p Value | |
|---|---|---|---|
| Mean (SD) age, years | 72.8 (9.1) | 69.9 (11.1) | <0.001 |
| Male gender (%) | 81 (55.1) | 2667 (53.8) | 0.750 |
| Current or former smoker (%) | 34 (23.1) | 1167 (23.5) | 0.911 |
| Family history of CRC (%) | 8 (5.4) | 81 (1.6) | 0.004* |
| Diverticulosis (%) | 70 (47.6) | 1258 (25.4) | <0.001 |
| Coronary artery disease (%) | 58 (39.5) | 1177 (23.7) | <0.001 |
Family history of CRC is defined as one first-degree relative <50 years or at least two first-degree relatives 50–70 years. Diverticulosis is defined as the presence of ≥2 diverticula. Coronary artery disease is defined as a history of myocardial infarction, angina, congestive heart failure or severe arrhythmias.
