Multivariate logistic regression analysis on parameters associated with metachronous lung metastases
| Parameter | Chi-square value | OR | 95% CI | P-value |
|---|---|---|---|---|
| Age (<65 vs. ≥65 years) | 0.890 | 1.163 | 0.849–1.593 | 0.35 |
| Location of primary cancer (rectum vs. colon) | 31.459 | 2.450 | 1.791–3.351 | <0.0001 |
| Maximum tumor diameter (>40 vs. ≤40 mm) | 0.852 | 0.862 | 0.629–1.182 | 0.36 |
| Depth (T3–4 vs. T0–2) | 0.771 | 1.168 | 0.825–1.654 | 0.38 |
| Regional lymph node metastasis (present vs. absent) | 44.182 | 2.967 | 2.155–4.098 | <0.0001 |
| Distant metastasis (M1 vs. M0) | 50.860 | 4.185 | 2.824–6.202 | <0.0001 |
| Family history of CRC (present vs. absent) | 1.786 | 1.350 | 0.869–2.098 | 0.18 |
OR, odds ratio, CI, confidence interval. CRC, colorectal cancer.
