TABLE 3.
Disease burden at time of baseline CTC draw vs PFS and OS
| Locally advanced disease | 0 CTCs (n = 19) | ≥1 CTCs (n = 6) | P value |
|---|---|---|---|
| Median PFS a (range), mo | 41.00 (4‐71) | 38.50 (25‐69) | .975 |
| Median OS b (range), mo | 44.40 (5‐72) | 40.30 (26‐70) | .555 |
| Metastatic disease | 0 CTCs (n = 7) | ≥1 CTCs (n = 4) | P value |
|---|---|---|---|
| Median PFS a (range), mo | 4.00 (1‐7) | 2.50 (1‐19) | .927 |
| Median OS b (range), mo | 11.13 (3‐21) | 5.37 (1‐19) | .412 |
Abbreviations: CTC, circulating tumor cells; OS, overall survival; PFS, progression‐free survival.
a
PFS is until disease progression or last available follow‐up.
b
OS is until death or last available follow‐up.
