  Purpose

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die.

PURPOSE: Phase II trial to study the effectiveness of gemcitabine in treating patients who have recurrent chronic lymphocytic leukemia.


Condition Intervention Phase
Leukemia
Drug: gemcitabine hydrochloride
Phase 2

Study Type: Interventional
Study Design: Primary Purpose: Treatment

Study Start Date: February 2000
Primary Completion Date: April 2008 (Final data collection date for primary outcome measure)
Detailed Description:

OBJECTIVES: I. Determine the rate and duration of complete and partial remission in patients with recurrent B-cell chronic lymphocytic leukemia treated with gemcitabine. II. Assess the toxicities of this regimen in these patients.

OUTLINE: Patients receive gemcitabine IV over 30 minutes on days 1 and 8. Treatment repeats every 4 weeks for a minimum of 3 courses. Patients achieving clinical complete remission, complete remission, nodular partial remission, or partial remission following 3 courses of therapy, receive 2 additional courses of therapy. Patients achieving complete remission or further improvement following the 2 additional courses of therapy, receive another 2 courses of therapy. Patients are followed every 3 months until disease progression or relapse. Patients achieving complete remission are followed every 6 months for 1 year.

PROJECTED ACCRUAL: A total of 15-30 patients will be accrued for this study within 6-12 months.

Criteria

DISEASE CHARACTERISTICS: Diagnosis of B-cell chronic lymphocytic leukemia manifested by all of the following: Minimum threshold peripheral lymphocyte count of at least 5,000/mm3 Small to medium sized peripheral blood lymphocytes with no greater than 55% prolymphocytes Bone marrow aspirate and biopsy containing at least 30% lymphoid cells Immunophenotypic and biopsy evaluation of peripheral blood lymphocytes demonstrating monoclonality of B lymphocytes B-cell markers with CD5 antigen (e.g., T-1, T-101) in the absence of other pan T-cell markers (e.g., CD3, CD2) Expression of CD19, CD20, and CD23 B cell surface markers B-cell expression of kappa or lambda light chains Active disease with at least one of the following criteria: One or more disease related symptoms: At least 10% weight loss within the past 6 months Fever greater than 100.5 F for at least 2 weeks without evidence of infection Night sweats without evidence of infection Evidence of progressive marrow failure as manifested by the development of or worsening of anemia (hemoglobin less than 11.0 g/dL) and/or thrombocytopenia (platelet count less than 100,000/mm3) (i.e., any stage III or IV disease) Autoimmune anemia and/or thrombocytopenia poorly responsive to corticosteroid therapy Massive (i.e., greater than 6 cm below the left costal margin) or progressive splenomegaly (i.e., a greater than 50% increase over two months) Massive (i.e., greater than 10 cm in longest diameter) or progressive lymphadenopathy (i.e., a greater than 50% increase over two months) Progressive lymphocytosis with an increase of greater than 50% over a 2 month period (unrelated to corticosteroids) or an anticipated doubling time of less than 6 months No marked hypogammaglobulinemia or the development of a monoclonal protein in the absence of any criteria for active disease Previously treated with at least a fludarabine or cladribine based regimen and a prior alkylating agent with evidence of recurrent or progressive disease
