Overall survival (OS, A) and progression-free survival (PFS, B) in the entire group. Analysis of OS (C) and PFS (D) by extranodal, nodal, and PCFCL groups shows no significant differences (P = 0.565, P = 0.627). Analysis of OS (E) and PFS (F) by t(14;18)−status shows better OS and trend for longer PFS than in t(14;18)+ cases (P = 0.019, P = 0.131). PCFCL indicates primary cutaneous follicle center lymphoma.
