Time to progression (TTP) after first therapy. (A) Patients with a complete response (CR), unconfirmed CR, or nodular partial response (Nod PR) experienced a significantly better TTP (51% at 3 years) than patients with a partial response (median TTP 14 months, P = .001 vs CR/Nod PR). Three patients with a partial response were not assessable due to inadequate follow-up of disease status. (B) Survival after first therapy. Patients with a complete response (CR), unconfirmed CR, or nodular partial response (Nod PR) experienced significantly better survival (86% at 3 years) than patients with a partial response (median survival 28 months, P = .05 vs CR/Nod PR) or patients with no response to treatment (median survival 20 months; P = .001 vs CR/Nod PR; P = .13 vs partial response).
