Effects of palliative resection and Lenti-MTSS1 on pulmonary metastasis
| Group | The total number of solitary pulmonary nodule | Lung metastatic extent (Grade)* | ||
|---|---|---|---|---|
| (n) | I | II | III-IV | |
| Palliative Resection | 35 | 12 | 11 | 12 |
| Sham Operation | 33 | 19 | 8 | 6 |
| Black Control | 32 | 20 | 7 | 5 |
| BBS | 32 | 9 | 10 | 13 |
| Lenti-GFP | 31 | 8 | 11 | 12 |
| Lenti-MTSS1 | 30 | 15 | 10 | 5 |
NOTE: All pulmonary metastases were verified via histological examination when mice were sacrificed 2 weeks following palliative resection, or receiving BBS, Lenti-GFP, or Lenti-MTSS1. Lung metastatic extent was graded by number of tumor cells counted in the maximum section of the solitary pulmonary metastatic nodule. *P = 0.039 or 0.041 when Palliative Resection group or Lenti-MTSS1 group was compared among Control groups, respectively
