The relationship between hematological malignancy and chemotherapy on the prevalence of antibiotic allergy label (AAL) is ill-defined. We performed a multicenter retrospective case-control study comparing AAL rates among cladribine-treated hairy cell leukemia (C-HCL) cases, non-HCL cladribine-treated controls (control-1), and fludarabine-treated controls (control-2). The prevalence of AALs in C-HCL patients was 60%, compared with control-1 (14%, < .

- Initial concerns were raised about statin use in lymphoma due to laboratory data suggesting it might hinder anti-CD20 antibody effectiveness, but later studies indicated potential benefits, particularly in follicular lymphoma patients.
- This study analyzed data from the PRIMA trial, focusing on 1,135 follicular lymphoma patients, with 10.5% of them using statins at diagnosis to evaluate their impact on treatment outcomes.
- Results showed no significant differences in event-free survival, time to next treatment, or overall survival between patients using statins and those who weren't, indicating that statin use does not affect prognosis in this group.
Purpose: Treatment options for patients with Waldenström macroglobulinemia (WM) and closely related disorders include alkylating agents, purine analogs, and monoclonal antibodies. No large randomized studies have yet been reported comparing any of these approaches.
Patients And Methods: The randomized WM1 study (Trial Comparing Chlorambucil to Fludarabine in Patients With Advanced Waldenström Macroglobulinemia) was undertaken in 101 centers in five countries enrolling 414 eligible patients (339 with WM, 37 with non-mucosa-associated lymphoid tissue marginal zone lymphoma, and 38 with lymphoplasmacytic lymphoma) who were randomly assigned to receive chlorambucil or fludarabine.
In patients with follicular lymphoma treated with single-agent rituximab, single nucleotide polymorphisms in the FCGR3A gene are known to influence response and progression-free survival. The prognostic role of FCGR3A and FCGR2A polymorphisms in patients with follicular lymphoma treated with rituximab and chemotherapy combination remains controversial and has not been evaluated in the context of rituximab maintenance. FCGR3A and FCGR2A single nucleotide polymorphisms were evaluated in, respectively, 460 and 455 patients treated in the PRIMA study to investigate whether these were associated with response rate and patient outcome after rituximab chemotherapy induction and 2-year rituximab maintenance.

We investigated the prognostic significance of PET-CT performed after first-line therapy in patients with FL treated in the prospective Primary Rituximab and Maintenance (PRIMA) study.
Patients And Methods: Results of PET-CT scans performed after induction immunochemotherapy were recorded retrospectively.
Background: Patients with follicular lymphoma can have long survival times, but disease progression typically occurs 3-5 years after initial treatment. We assessed the potential benefit of 2 years of rituximab maintenance after first-line treatment in patients with follicular lymphoma receiving a rituximab plus chemotherapy regimen.
Methods: The randomised, open-label PRIMA study was undertaken in 223 centres in 25 countries.
