| No. of Patients | No. of Relapses (%) | PFS Rate at 2 Years (95% CI) | p Value by log rank test | |
|---|---|---|---|---|
| CTC-positive | 27 | 7 (26%) | 75% (0.6–0.9) | 0.03 |
| CTC-negative | 23 | 1 (4%) | 92% (0.8–1.0) | |
| No. of patients | No. of deaths (%) | OS rate at 2 years (95% CI) | ||
| CTC-positive | 27 | 3 (11%) | 91% (0.8–1.0) | 0.09 |
| CTC-negative | 23 | 0 (0) | 100% |
Abbreviations: CI, confidence interval; CTC, circulating tumor cells; No, number; PFS, progression-free survival; OS, overall survival.
