Diffuse Large B-Cell Lymphoma: Relapsed/Refractory

What is Lymphoma?

Diffuse Large B-Cell Lymphoma: Relapsed/Refractory

The term “relapsed” refers to disease that reappears or grows again after a period of remission.

The term “refractory” is used to describe when the lymphoma does not respond to treatment (meaning that the cancer cells continue to grow) or when the response to treatment does not last very long.

High-dose chemotherapy followed by stem cell transplantation can be used to treat patients with DLBCL whose disease is refractory or relapsed following initial chemotherapy. The majority of patients undergoing stem cell transplantation will have an autologous transplant (patient receives his or her own stem cells, collected prior to the procedure). Occasionally, a patient will undergo an allogeneic transplant (patient receives stem cells from a donor).

For those relapsed/refractory patients combination chemotherapy regimens are available. These second-line regimens include:

  • ifosfamide, carboplatin, and etoposide (ICE)
  • dexamethasone, cisplatin, and cytarabine (DHAP)
  • gemcitabine-based therapy
  • bendamustine (Treanda) plus rituximab (Rituxan)
  • lenalidomide (Revlimid) plus rituximab (Rituxan)
  • polatuzumab vedotin-piiq (Polivy)
  • selinexor (Xpovio)
  • tafasitamab-cxix (Monjuvi)
  • epcoritamab-bysp (Epkinly)
  • glofitamab-gxbm (Columvi)

For some relapsed/refractory patients a form of immunotherapy called chimeric antigen receptor (CAR) T-cell therapy, may be a possible treatment option. The approved CAR T-cell therapies include:

  • axicabtagene ciloleucel (Yescarta)
  • Lisocabtagene Maraleucel (liso-cel, Breyanzi)
  • tisagenlecleucel (Kymriah)

To learn more about CAR T-cell therapy, visit the CAR T-Cell Therapy Learning Center or download the CAR T-Cell Therapy Fact Sheet.

For those relapsed/refractory patients who have a subset of DLBCL called primary mediastinal large B-cell lymphoma (PMBCL). These second-line regimens include:

  • pembrolizumab (Keytruda)
