Rituximab dosing in B cell lymphoma
نویسندگان
چکیده
Rituximab has been extensively used in the treatment of CD20-expressing B cell neoplasms in the last two decades. Despite that, its dose and scheduling are still being questioned as they are inadequately supported by data. Our retrospective study of patients with indolent B cell lymphoma showed that older males and patients with higher weight had worse outcomes when treated with first line rituximab-containing chemotherapy, probably due to faster rituximab clearance. This suggests that a subset of patients with indolent B cell lymphoma may be sub-optimally dosed with rituximab as commonly administered. These results are in line with other studies in aggressive lymphoma where rituximab pharmacokinetics were shown to be affected by gender, age and weight and can affect outcomes. Our study also highlights the challenge of presenting the newer anti-CD20 monoclonal antibodies as intrinsically superior to rituximab when they are given at higher dose and more frequent administration.

Development of DOTA-Rituximab kit formulation to be labeled with 90Y for radioimmunotherapy of B-cell Non-Hodgkin Lymphoma
NHL is the most common hematologic cancer in adults. Rituximab is the FDA approved treatment of relapsed or refractory low grade B-cell Non-Hodgkin Lymphoma (NHL). But patients eventually become resistant to rituximab. Since lymphocytes and lymphoma cells are highly radiosensitive, low grade NHL that has relapsed or refractory to standard therapy is treated by RIT in which a beta-emitting radio...

متن کاملDiffuse large B-cell lymphoma: changing treatment paradigms.
Diffuse large B-cell lymphoma (DLBCL) was first cured with anthracycline-based chemotherapy in the 1970s. In the late 1990s, the addition of rituximab to cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) chemotherapy increased 10-year overall survival by approximately 15%. Two decades of variations on chemotherapy regimens and dosing schedules and upfront transplant have demonst...
متن کاملA systematic review evaluating the efficacy of autologous hematopoietic transplantation for diffuse large B cell lymphoma-type Richter syndrome
Background: Chronic lymphocytic leukemia (CLL) can transform into fast growing lymphoma for diffuse large B-cell lymphoma (DLBCL) called Richter's syndrome (RS), which is commonly related to an existence of large B-cells with equal or larger size than macrophage nuclei or more than twice those of normal lymphocyte. We conducted a systematic review of the existing literature to assess the clinic...
متن کاملRituximab in the Management of Follicular Lymphoma
The incidence of follicular lymphoma, a low-grade malignant B-cell lymphoma, is increasing in most Asian populations. Follicular lymphoma is generally considered to be indolent with a life expectancy of approximately 10 to 14 years. However, it is characterised by repeated relapse, and disease progression typically occurs 3 to 5 years after initial treatment. Rituximab, a monoclonal antibody, d...
