When does PMBCL relapse?
PMBCL can relapse or prove refractory to therapy early, with a median time to progression of eight months from diagnosis; most cases occur while on therapy or within 12 months of completion.
Does PMBCL return?
When PMBCL Comes Back PMBCL treatments often work well to get rid of this cancer. But if it comes back, you may have other options. The FDA has approved an immunotherapy drug called pembrolizumab (Keytruda) for people whose PMBCL doesn’t respond to chemo or has come back.

In the United States, the CHOP regimen (cyclophosphamide, doxorubicin, vincristine, prednisone) and subsequent R-CHOP (rituximab-CHOP), which are well established in DLBCL, have historically been the standard treatment of PMBCL.
Is PMBCL genetic?
As discussed in “JAK-STAT signaling,” amplification of a well-defined region on chromosome 9p24 has been identified in the majority of cases and can be considered as one of the genetic hallmark events of PMBCL pathogenesis.
How rare is PMBCL?
Primary mediastinal B-cell lymphoma (PMBCL) is relatively rare B-cell non-Hodgkin lymphoma that comprises 6–12% of all diffuse large B-cell lymphomas (DLBCLs) and 2–4% of all non-Hodgkin lymphomas.
How do you treat a DLBCL relapse?
Salvage high-dose chemotherapy followed by autologous stem cell transplantation is the standard of care for chemosensitive relapses in DLBCL. Various salvage regimens are available, but the quest for an optimal regimen continues. The addition of rituximab to the salvage regimen has improved the outcome of RR DLBCL.
What is primary mediastinal?
Primary mediastinal large B-cell lymphoma (PMBCL) is a type of non-Hodgkin lymphoma (NHL). It is sometimes called primary thymic mediastinal lymphoma. PMBCL develops when B-cells become abnormal (cancerous). B-cells are white blood cells that normally help fight infection. They are sometimes called B-lymphocytes.
