Kaplan and Meier plots of patients with cutaneous T-cell lymphoma.

(A) Survival of individuals with cutaneous T-cell lymphoma according to T-cell–receptor immunophenotype. A comparison was made between patients with alpha-beta (dotted line) and gamma-delta (solid line) cutaneous T-cell lymphomas. Significance was determined by the log-rank test. (B) Survival of individuals with cutaneous T-cell lymphoma according to histologic profile. A comparison of survival was made between patients with subcutaneous involvement (dotted line), and epidermotropic and/or dermal involvement (solid line). Significance was determined by the log-rank test. (C) Survival of individuals with cutaneous gamma-delta T-cell lymphoma according to histologic profile. A comparison of survival was made between patients with subcutaneous involvement (dotted line), and epidermotropic and/or dermal involvement (solid line). Significance was determined by the log-rank test. (D) Survival of patients presenting with cutaneous tumors according to T-cell–receptor immunophenotype. A comparison was made between patients with alpha-beta (dotted line) and gamma-delta (solid line) cutaneous T-cell lymphomas. Significance was determined by the log-rank test.
