Genetic Determinations for Side Effects and Response Rate for Patients Receiving Chemotherapy With Diffuse Large Cell Lymphoma

Candidate Gene Polymorphisms and Response to Rituximab-CHOP in Patients With Diffuse Large Cell Lymphoma

The purpose of this study is to determine whether people have genes that make them more likely to respond to chemotherapy and/or have side effects from chemotherapy for diffuse large cell lymphoma.

Detailed Description

Upon enrollment in the study, patients will have a blood sample collected for genotyping of the FCGR3A gene (immunoglobulin Fc G receptor IIIa), the ABCB1 gene (ATP Binding Cassette Beta 1; also called MDR1), and other candidate genes. Patients will be treated with R-CHOP for six cycles, which is standard therapy for advanced stage DLCL. Response will be monitored by an FDG-PET scan performed after 2 cycles of R-CHOP and restaging exams performed upon completion of chemotherapy. Gene polymorphisms will be analyzed to establish which polymorphisms predict response to R-CHOP.

Description

Inclusion Criteria:

  • Histologically proven diffuse large B-cell non-Hodgkin's lymphoma according to the WHO classification, with measurable or evaluable disease
  • No prior therapy for NHL. Patient may be enrolled in this study after the first cycle of R-CHOP if all screening evaluations were performed prior to the first cycle of chemotherapy.
  • Ann Arbor stage 3 or 4
  • Age greater than or equal to 18 years
  • Patient must give written informed consent.
  • A patient enrolled in another clinical trial may also enroll in this study if the other trial has an R-CHOP treatment arm and the patient is randomized to the R-CHOP only arm. Registration to this study must occur after randomization in the other trial.

Exclusion Criteria:

  • CNS involvement
  • Known HIV positive
  • T-cell lymphoma or history of indolent NHL
  • Patients who will be treated with radiation therapy

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: R-CHOP
Patients receiving R-CHOP via standard of care which consists of cyclophosphamide 750 mg/m2 IV day 1 of each 21 day cycle, doxorubicin 50 mg/m2 IV day 1 of each 21 day cycle, vincristine 1.4 mg/m2 IV day 1 of each 21 day cycle, prednisone 100 mg PO days 1-5 of each 21 day cycle, and rituximab 375 mg/m2 IV day 1 of each 21 day cycle.
Sample Collection for Genotyping prior to cycle 1 treatment of R-CHOP, if patient is enrolled after cycle 1, sample for genotyping should be collected prior to cycle 2.
