Treatment Protocols

Treatment recommendations for patients with diffuse large B-cell lymphoma (DLBCL) begin with evaluating the extent of the disease, performance status of the patient, and histologic subtypes. Treatment of localized and advanced disease varies considerably.

Below is a general treatment algorithm for DLBCL, followed by treatment recommendations for different stages of disease and for relapsed or refractory disease. [1, 2, 3]

General DLBCL treatment algorithm

Diagnosis of DLBCL:

  • Staging/IPI score/bulky disease
  • Assess end-organ function
  • Establish therapy endpoints (ie, cure vs palliation)

Stage I/II (nonbulky) disease:

  • Rituximab (R) plus cyclophosphamide, vincristine, doxorubicin, and prednisone (CHOP) for 3-4 cycles
  • Follow with involved field radiation therapy (IFRT)
  • If positron emission tomography (PET) is positive after 4 cycles, administer 2 more cycles before IFRT
  • If relapse occurs, see step 4

Advanced-stage (stage III-IV) or bulky stage II disease:

  • R+CHOP every 21 d for 6 cycles, with or without IFRT for bulky sites
  • Prophylactic intrathecal (IT) chemotherapy in selected cases or
  • Clinical trial with correlative science studies (eg, R+CHOP-like and other biological agents or small molecules and/or other novel monoclonal antibodies [mAbs] or immunoconjugates)

In cases of relapse:

  • Staging/IPI score/bulky disease
  • Assess end-organ function

In relapse patients, collect lymphoid tissue and store for future analysis or current research evaluating gene profiling, proteomic analysis, biomarkers of disease (MUM-1, Bcl-6, and CD10), and preclinical studies with novel agents

Relapse patients eligible for high-dose chemotherapy (HDC) and autologous stem cell transplantation (ASCT):

  • Platinum-based salvage chemotherapy, [4] including rituximab, ifosfamide, carboplatin, and etoposide (RICE) for 2-3 cycles or
  • Rituximab plus cisplatin, cytarabine, and dexamethasone (DHAP) for 2-3 cycles
  • If partial or complete response is achieved, use HDC and ASCT
  • Observation or clinical trials evaluating agents in the maintenance setting may be recommended
  • If patient relapses, consider clinical trials evaluating novel agents (eg, bortezomib, lenalidomide, or immunoconjugates) or
  • Radioimmunotherapy (RIT)

Relapse patients not eligible for HDC and ASCT:

  • Palliative chemotherapy (gemcitabine-based therapyClinical trials evaluating novel agents (eg, bortezomib, lenalidomide, or immunoconjugates) or
  • RIT

Treatment recommendations for early-stage disease

Stage I and selected stage II:

Patients without adverse risk factors present:

  • R+CHOP: Combined therapy with rituximab 375 mg/m2 IV on day 1 plus cyclophosphamide 750 mg/m2 IV on day 1 or 3 plus doxorubicin 50 mg/m2 IV on day 1 or 3 plus vincristine 1.4 mg/m2 (maximum dose, 2 mg) IV on day 1 or 3 plus prednisone 40 mg/m2 PO on days 1-5 or 3-8; every 21d for 3 cycles [5]

  • Radiographic studies including functional imaging (eg, PET scan) to document response to treatment should be done before initiation of IFRT and/or at the end of therapy

  • Always confirm residual PET abnormalities with biopsy before modifying therapy

Patients with adverse risk factors present:

  • R+CHOP: Combined therapy with rituximab plus  cyclophosphamide 750 mg/m2 IV on day 1 or 3 plus  doxorubicin 50 mg/m2 IV on day 1 or 3 plus  vincristine 1.4 mg/m2 (maximum dose, 2 mg) IV on day 1 or 3 plus  prednisone 40 mg/m2 PO on days 1-5 or 3-8; every 21d for 3 cycles followed by IFRT [5] or

  • R+CHOP: Rituximab 375 mg/m2 IV on day 1 plus  cyclophosphamide 750 mg/m2 IV on day 1 or 3 plus  doxorubicin 50 mg/m2 IV on day 1 or 3 plus  vincristine 1.4 mg/m2 (maximum dose, 2 mg) IV on day 1 or 3 plus  prednisone 40 mg/m2 PO on days 1-5 or 3-8; every 21d for 6 cycles with or without IFRT [6]

  • Radiographic studies including functional imaging (eg, PET scan) to document response to treatment should be done before initiation of IFRT and/or at the end of therapy

  • Always confirm residual PET abnormalities with biopsy before modifying therapy

Treatment recommendations for advanced-stage disease

Stages III-IV:

  • R+CHOP: Rituximab 375 mg/m2 IV on day 1 plus  cyclophosphamide 750 mg/m2 IV on day 1 or 3 plus  doxorubicin 50 mg/m2 IV on day 1 or 3 plus  vincristine 1.4 mg/m2 (maximum dose, 2 mg) IV on day 1 or 3 plus  prednisone 40 mg/m2 PO on days 1-5 or 3-8; every 21d for 6 cycles with or without IFRT [6, 7]

  • Consider radiation therapy to bulky sites of disease at the end of chemoimmunotherapy

Prophylactic intrathecal chemotherapy (selected cases)

Prophylactic IT chemotherapy with low-dose methotrexate (eg, 12 mg) should be routinely administered to DLBCL patients with the following characteristics [8, 9] :

  • More than one extranodal site of disease
  • Testicular or breast involvement, regardless of stage
  • Lymphoblastic variants
  • Oropharyngeal or paraspinal sites of involvement
  • Bone marrow involvement
  • Concomitant HIV infection

Treatment recommendations for relapsed or refractory disease

Patients eligible for HDC-ASCT (treatment goal = cure):

A vast number of regimens are used in the treatment of patients with relapsed or refractory DLBCL. These are primarily based on chemotherapy agents that are not cross-resistant to those used in the front-line setting, with or without rituximab. The goal of salvage regimens is to achieve maximum tumor burden cytoreduction in preparation for HDC with ASCT (HDC-ASCT). [10]
