A 77-Year-Old Woman with DLBCL

September 25, 2020

John M. Burke, MD, of Rocky Mountain Cancer Centers, explains the rationale behind treating an elderly woman with relapsed diffuse large B-cell lymphoma with tafasitamab and lenalidomide after R-CHOP chemotherapy.


Case: A 77-Year-Old Woman With DLBCL

Initial Presentation

  • A 77-year-old woman presented with loss of appetite, fatigue and shortness of breath
  • PMH: post-menopausal; DM, medically controlled
  • PE: palpable inguinal lymphadenopathy; splenomegaly
  • ECOG PS 1

Clinical Work-up

  • Labs: Hb 9.8 g/dL; all others WNL
  • FEV1 45 %
  • Hepatitis B, C and HIV negative
  • Core needle biopsy of the inguinal node: CD20-positive diffuse large B-cell lymphoma, non-GCB subtype. FISH panel: t(14;18) with a BCL2 rearrangement; no MYC or BCL6 rearrangement
  • Imaging:
    • Whole body PET/CT scan showed FDG avidity the inguinal lymph node region, largest node 3.3 cm; splenomegaly; and a small suspicious lung lesion
  • Bone marrow biopsy: involvement with DLBCL
  • Conclusion: stage IV DLBCL, non-GCB subtype
  • IPI score high-risk; CNS relapse score intermediate risk

Treatment

  • Treated with R-CHOP for 6 cycles
  • End-of-treatment PET/CT demonstrates a Deauville 2 complete remission
  • 1 year later while in surveillance she presents with new cervical, axillary, mediastinal, and abdominal lymphadenopathy
  • Core needle biopsy of an axillary node confirms a relapse of DLBCL, non-GCB subtype
  • Based on her age of 78 years and performance status, you consider her to be transplant-ineligible
  • You elect to initiate tafasitamab + lenalidomide
