Analysis of the metastasis rate and survival time of LLC-1 xenograft mice.
| All cases (%) | Metastasis (%)a | p valueb,c | |
|---|---|---|---|
| Total | 31 (100%) | 5 (16.1%) | |
| Water type | 0.048 | ||
| DI | 17 (54.8%) | 5 (100%) | |
| PIA | 14 (45.1%) | 0 (0%) | |
| Survival days (mean ± SD) | |||
| Total | 6.34 ± 0.41 | ||
| Treatment | |||
| DI | 4.62 ± 0.71 | ||
| DI + Cs | 6.38 ± 0.61 | 0.081 | |
| PIA | 6.57 ± 0.66 | 0.118 | |
| PIA + Cs | 8.01 ± 0.77 | 0.009 | |
aLung metastasis was examined by gross observation of the whole lung.
bp values were analyzed by a two-tailed Fisher test.
cp values were analyzed by a log-rank test compared to the DI (DI water alone, n = 9) group and DI + Cs (DI water plus cisplatin, n = 8), PIA (PIA water, n = 7), or PIA + Cs (PIA water plus cisplatin, n = 7) group.
