Disease progression patterns according to BRAF mutational status and primary tumor location
| Disease progression pattern, N (%) | BRAF-WT (N = 54) | BRAF-MT (N = 12) | Left-sided tumor (N = 70) | Right-sided tumor (N = 16) |
|---|---|---|---|---|
| New lesion/s | 6 (11.1) | 1 (8.3) | 8 (11.4) | 1 (6.3) |
| Progression of target lesion/s | 13 (24.1) | 3 (25.0) | 18 (25.7) | 4 (25.0) |
| Progression of non-target lesion/s | 1 (1.9) | 1 (8.3) | 1 (1.4) | 1 (6.3) |
| New lesion/s and progression of target lesion/s | 3 (5.6) | 0 (0.0) | 4 (5.7) | 0 (0.0) |
| New lesion/s and progression of non-target lesion/s | 2 (3.7) | 0 (0.0) | 1 (1.4) | 1 (6.3) |
| Progression of target and non-target lesions | 2 (3.7) | 3 (25.0) | 6 (8.6) | 3 (18.8) |
