TCR Clonality Results and T-Classification of MF
| T-classification | TCRG (positive/total) | TCRB (positive/total) | TCRG and TCRB* (positive/total) | TCRG or TCRB† (positive/total) |
|---|---|---|---|---|
| T1 | 3/10 (30%) | 6/10 (60%) | 2/10 (20%) | 7/10 (70%) |
| T2 | 10/11 (90.9%) | 7/11 (63.6%) | 7/11 (63.6%) | 10/11 (90.9%) |
| T3 | 11/15 (73.3%) | 9/15 (60%) | 9/15 (60%) | 11/15 (73.3%) |
| T4 | 6/8 (75%) | 6/8 (75%) | 6/8 (75%) | 6/8 (75%) |
| MF (total) | 30/44 (68.2%) | 28/44 (63.6%) | 24/44 (54.5%) | 34/44 (77.3%) |
T-classification system: T1, patches/plaques <10% body surface area; T2, patches/plaques ≥10% body surface area; T3, tumors (rounded or dome-shaped lesions >1 cm in diameter); T4, generalized erythroderma (>80% of body surface is affected).
*
A final positive test result was called for a certain sample when both TCRG and TCRB tests were positive, and a final negative test result was called when at least one test was negative.

A final positive test result was called for a certain sample when at least one test was positive, and a final negative test result was called when both tests were negative.
