About
RATIONALE: Sometimes the cancer may not need treatment until it progresses. In this case, observation may be sufficient. Giving combination chemotherapy together with bortezomib, thalidomide, and rituximab before an autologous peripheral stem cell transplant stops the growth of cancer cells by stopping them from dividing or killing them. Giving colony-stimulating factors, such as G-CSF, helps stem cells move from the bone marrow to the blood so they can be collected and stored. More chemotherapy is then given to prepare the bone marrow for the stem cell transplant. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy.
PURPOSE: This observational and phase II trial is studying how well giving combination chemotherapy together with bortezomib, thalidomide, and rituximab followed by two autologous peripheral blood stem cell transplants works in treating patients with Waldenstrom macroglobulinemia.
Full description
OBJECTIVES:
Primary
- To assess the progression-free and overall survival of patients with symptomatic Waldenstrom macroglobulinemia treated with bortezomib, dexamethasone, thalidomide, cisplatin, doxorubicin hydrochloride, cyclophosphamide, and etoposide (VDT-PACE) in combination with rituximab, followed by single or tandem autologous peripheral blood stem cell transplantation and maintenance therapy.
- To assess the confirmed and unconfirmed response in patients treated with this regimen.
Secondary
- To evaluate the feasibility and toxicity of this regimen in these patients.
- To correlate the time to symptom development and overall survival with standard prognostic factors and cytopenias.
- To examine the natural history of Waldenstrom macroglobulinemia.
- To identify, in a preliminary fashion, biological correlates that may relate to progression or to symptomatic disease.
OUTLINE: This is a multicenter study. Patients with asymptomatic disease at study entry proceed directly to observation. Patients with symptomatic disease at study entry proceed directly to induction therapy.
- Observation: Patients with asymptomatic disease undergo observation monthly for 3 months and then every 3 months for up to 3 years. Patients who develop symptomatic disease proceed to induction therapy within 28 days of onset of disease symptoms. Patients who continue to have asymptomatic disease after 3 years of observation are removed from the study.
- Induction therapy: Patients receive oral dexamethasone and oral thalidomide on days 1-4; cisplatin IV, doxorubicin hydrochloride IV, cyclophosphamide IV, and etoposide IV continuously on days 1-4; bortezomib IV on days 1, 4, 8, and 11; and rituximab IV on days 1, 8, and 15. Treatment repeats every 6-8 weeks for 2 courses in the absence of disease progression or unacceptable toxicity.
- Peripheral blood stem cell (PBSC) collection: Patients receive filgrastim (G-CSF) IV beginning on day 9 of course 1 of induction therapy and continuing until WBC counts are adequate for apheresis. Patients also receive G-CSF IV beginning on day 6 of course 2 of induction therapy and continuing until apheresis is complete.
- First autologous PBSC transplantation*: Beginning approximately 4-6 weeks after the completion of induction therapy, patients receive conditioning therapy comprising high-dose melphalan IV and bortezomib IV on days -4 and -1. Patients undergo autologous PBSC transplantation on day 0 NOTE: *Patients who will receive a single transplant (for medical, insurance, or other reasons) will not receive melphalan and bortezomib, but will receive conditioning with carmustine, etoposide, cytarabine, and melphalan (BEAM) and will proceed to Maintenance Therapy.
- Second autologous PBSC transplantation: Beginning approximately 56-90 days after the first transplant, patients receive conditioning therapy comprising carmustine IV over 2 hours on day -5; etoposide IV over 1 hour and cytarabine IV over 1 hour on days -5 to -2; and melphalan IV on day -1. Patients undergo autologous PBSC transplantation on day 0.
- Maintenance therapy: Beginning after platelet counts recover, patients receive bortezomib IV on days 1, 4, 8, and 11 and rituximab IV over 2 hours on day 11. Treatment repeats every 3 months for 2 years in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed every 6 months for up to 5 years.

Inclusion and exclusion criteria
DISEASE CHARACTERISTICS:
-
Diagnosis of Waldenstrom macroglobulinemia (WM)
-
Measurable disease as determined by IgM protein quantification
-
Must be registered to the treatment portion of the study within 28 days of experiencing disease-related symptoms* AND must present with ≥ 1 of the following disease-related symptoms:
- Hemoglobin ≤ 11 g/dL
- Platelet count ≤ 100,000/mm³
- Marked tumor mass, defined as lymphadenopathy > 2 cm, palpable hepatomegaly, splenomegaly, or significant marrow involvement (> 50%)
- Serum albumin < 2.5 g/dL
- Persistently elevated beta-2-microglobulin > 3.0 mg/L in the absence of renal impairment or active infections
- Presence of B symptoms (i.e., fever, night sweats, or weight loss of > 10% from baseline)
- Appearance of new or worsening neuropathy manifested by numbness and tingling or pain
- Symptomatic cryoglobulinemia (i.e., Raynaud phenomenon, skin ulcers, cold urticaria, or skin necrosis)
- Symptoms of hyperviscosity, if measured viscosity > 4 cp (i.e., new headaches, vertigo, ataxia, dizziness with or without evident causes of changes in funduscopic exam, including retinal vein engorgement, hemorrhages, or exudates)
-
NOTE: *Appearance of any of the above symptoms caused by WM with no other obvious cause is a trigger for treatment initiation. Symptoms need not persist for any specified time frame.
PATIENT CHARACTERISTICS:
-
Zubrod performance status 0-2 (Zubrod performance status 3 allowed provided it is based solely on morbidity due to WM)

- Patients with evidence of amyloidosis (i.e., periorbital perforation, proteinuria not attributable to Bence-Jones protein, unexplained arrhythmias, increased liver function tests, peripheral neuropathy, carpal tunnel syndrome, and/or macroglossia) must have an ECHO, rather than MUGA, performed to evaluate for cardiac amyloidosis (septal thickness, diastolic dysfunction, granular sparkling, or low-voltage QRS complexes)
