Table 1. Clinicopathologic parameters of eight CRC patients.
| Case | Age/sex | MSI status | Location | Diameter of primary cancer (cm) | Differentiation | T | N | M | TNM | Associated adenomas | Tumor cell content (%) |
|---|---|---|---|---|---|---|---|---|---|---|---|
| MSS1 | M/69 | MSS | Sigmoid | 6.0 | Poor | 3 | 2 | 1 | IVA | Tubular, high grade | >70 |
| MSS2 | M/61 | MSS | Sigmoid | 11 cm | Well | 4 | 0 | 0 | IIB | Tubulovillous, high grade | >70 |
| MSS3 | F/69 | MSS | Transverse | 8 cm | Well | 2 | 0 | 0 | I | Tubular, high grades | >70 |
| MSS4 | F/80 | MSS | Ascending | 4.5 cm | Moderate | 3 | 0 | 0 | IIA | Villous, high grade | >70 |
| MSU1 | M/68 | MSI-H | Ascending | 10 cm | Mucinous | 3 | 0 | 0 | IIA | Tubulovillous, high grade | >70 |
| MSU2 | M/66 | MSI-H | Cecal | 7.0 cm | Mucinous | 3 | 0 | 0 | IIA | Villous, high grade | >70 |
| MSU3 | F/51 | MSI-H | Transverse | 5.0 cm | Moderate | 3 | 0 | 0 | IIA | Tubulovillous, high grade | >70 |
| MSU4 | F/76 | MSI-H | Ascending | 9.5 cm | Moderate | 3 | 2 | 0 | IIB | Tubulovillous, high grade | >70 |
The eight cases are distinguished into four MSS (microsatellite stable) cases (MSS1-4) and four MSU (microsatellite unstable) cases (MSU1-4) with MSI-H (microsatellite instability-high) according to the MSI calls.
