Description

Background: Due to their synergistic action and non-overlapping toxicity profiles, the combination of Rituximab and Fludarabine is the treatment of choice for advanced stage chronic lymphocytic lymphoma (CLL)/small lymphocytic lymphoma (SLL). As such, we have designed this protocol to better understand the genetic basis of CLL/SLL, to identify predictors of treatment response and to study the molecular effects of Rituximab Fludarabine on the leukemic cells. A new technology utilizing complementary deoxyribonucleic acid (cDNA) microarrays now permits the simultaneous quantitation of the exp...

Eligibility criteria

  • INCLUSION CRITERIA:
  • Diagnosis of chronic lymphocytic lymphoma (CLL)/small lymphocytic lymphoma (SLL) will be made according to the World Health Organization (WHO) diagnostic classification. A lymphocyte count in excess of 5000/mcl is typically found in the leukemic variant but is not a pre-requisite for a diagnosis of SLL. Low, Intermediate or High-Risk Category of CLL/SLL, using the Modified Three-Stage Rai Staging System as follows:
  • Risk Category: Low Risk
  • Rai Stage: 0
  • Clinical Features: Elevated blood and marrow lymphocyte numbers only (L). (lymphocytes greater than 5000/microl in blood, and lymphocytes greater than 30 percent in marrow).
  • Risk Category: Intermediate Risk
  • Rai Stage: I
  • Clinical Features: L + enlarged lymph nodes (LN)
  • Risk Category: Intermediate Risk
  • Rai Stage: II
  • Clinical Features: L + enlarged spleen or liver
  • Risk Category: High Risk
  • Rai Stage: III
  • Clinical Features: L + anemia (Hemoglobin less than 11 gm/dl)
  • Risk Category: High Risk
  • Rai Stage: IV
  • Clinical Features: L + thrombocytopenia (platelets less than 100,000/microl)
  • Patients in the modified Rai high risk group and select patients in the intermediate risk group will undergo treatment with Rituximab Fludarabine. To meet treatment criteria patients in the intermediate risk group should have evidence of active disease as demonstrated by at least one of the following criteria:
  • massive or progressive splenomegaly or lymphadenopathy;
  • presence of weight loss greater than 10% over the preceding 6 months;
  • constitutional symptoms of extreme fatigue, night sweats or recurrent fever of greater than 100 degrees F (documented fevers must be occurring without evidence of specific infection), and bone pain;
  • progressive lymphocytosis with an increase of greater than 50% over a 2 month period, or an anticipated doubling time of less than 6 months;
  • chronic infections either increased number or prolonged infections;
  • other high risk prognostic indicators such as excess elevation of beta-2-microglobulin, cluster differentiation 38 (CD38) expression and adverse cytogenetics may be used to better appraise the risk in each individual patient.
  • Patients with a diagnosis of CLL/SLL who do not meet the eligibility criteria for receiving Rituximab and Fludarabine (are not intermediate- or high-risk CLL/SLL), can enroll on the protocol for the purpose of donating cellular products. Such patients will not receive rituximab and fludarabine chemotherapy. At a later date, if it is documented that the patient does meet the criteria, then the patient may receive Rituximab and Fludarabine (after discussion with the Principal Investigator).
  • In a limited number of cases, patients with low-risk CLL/SLL may be initiated on Rituximab and Fludarabine treatment. For example, individuals who are candidates for bone marrow transplantation may be started on Rituximab Fludarabine as an induction regimen prior to transplantation. Additionally, some low-risk patients may be started on Rituximab and Fludarabine for psychological reasons (patient insistence on starting chemotherapy prior to disease progression). However, it must be stressed that low-risk CLL/SLL patients will be discouraged from initiating therapy except in these specific cases.
  • Age greater than or equal to 18 years of age.
  • Patients must have received no prior cytotoxic or monoclonal antibody therapy.
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2.
  • Required initial laboratory tests: Blood urea nitrogen (BUN) and Creatinine values must be less than or equal to 1.5 times the normal values; alternatively, patients with creatinine clearance of greater than 50 ml per minute will also be eligible. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) values must be less than or equal to 2.0 times normal values; patients with laboratory values greater than these levels may be enrolled on the protocol (after a specific approval from the Principal Investigator) if the values are due to a known, pre-existing liver disease. Bilirubin must be less than or equal to 2.0 mg/dl unless due to Gilbert's disease.
  • The patient must be competent to sign an informed consent, and sign the protocol consent form.
  • EXCLUSION CRITERIA:
  • Patients must not be pregnant or breastfeeding.
  • Patients with active autoimmune hemolytic anemia (AIHA)) grade III or higher (transfusion or steroids indicated) or immune thrombocytopenia (ITP) grade III or higher (platelets less than 50,000/microL) shall not be enrolled. Patients with a history of prior therapy to control either AIHA or ITP will be eligible, provided they do not require maintenance corticosteroids, and have not received monoclonal antibody therapy in the past 6 months. Patients developing AIHA or ITP on protocol may be managed as medically indicated on protocol but will generally not undergo fludarabine/rituximab treatment until resolution of hemolysis or thrombocytopenia to less than grade III.
  • Any patient with a medical condition that requires chronic use of corticosteroids shall not be enrolled.
