Table 3. NICD1 staining in peripheral T cell lymphomas.

Tumor Type (N=55 Total Cases)		NICD1 Staining Results
Angioimmunoblastic lymphoma (N=14)		86% positive (N=12; all subset positive)
Peripheral T cell lymphoma, NOS (N=12)		42% positive (N=5; all subset positive)
Cutaneous T cell lymphoma (N=12)		17% positive (N=2; all subset positive)
Anaplastic large cell lymphoma (ALCL, N=7)		14% positive (N=1; subset positive, ALK+ tumor)
		86% negative (N=6, 1 ALK+ tumor, 5 ALK-tumors)
Adult T cell leukemia/lymphoma (N=5)		20% positive (N=1; diffusely positive)
EBV+ T/NK extranodal lymphoma (N=4)		0% positive
Subcutaneous paniculitis-like T cell lymphoma (N=1)		0% positive

NOS, not otherwise specified; ALK, anaplastic lymphoma kinase; EBV, Epstein–Barr virus; NK, natural killer cell

Diffusely positive, ≥80% of cells positive; subset positive, ≤80% of cells positive
