Table 2. Recurrence patterns according to morphology findings.
Recurrence pattern | Total | Morphology of CTCs | |||
---|---|---|---|---|---|
Not detected (n=58) | Single only (n=6) | Cluster (n=17) | P value | ||
No recurrence | 65 (100.0) | 55 (84.6) | 4 (6.2) | 6 (9.2) | <0.01 |
Local | 2 (100.0) | 0 (0) | 1 (50.0) | 1 (50.0) | |
Regional | 7 (100.0) | 3 (42.9) | 0 (0) | 4 (57.1) | |
Distant | 7 (100.0) | 0 (0) | 1 (14.3) | 6 (85.7) |
Data are reported as number (%). Single only, only a single CTC was detected; Cluster, CTC clusters were detected. CTC, circulating tumor cell.
