Patient Understanding of Chemotherapy and Goals of Care as Provided by Different Care Team Members.

Chemotherapy can be challenging and overwhelming for patients, but when patients are knowledgeable about chemotherapy, their comfort level, overall satisfaction, and coping improve. It is currently unknown whether patients prefer information about chemotherapy to be provided by specific care team members and whether demographic characteristics affect learning preferences. We developed a 31-question questionnaire that asked patients when chemotherapy information was discussed and who they wanted that information to come from. The questionnaire was given to 50 patients who had completed 1 cycle of chemotherapy. Patients were evenly distributed among age categories of 45 to 64 years, 65 to 74 years, and 75 years or older. Thirty participants (60%) were women, 33 (66%) had high school degrees, and 23 (46%) were receiving their first chemotherapy regimen. Sixty percent of patients best understood goals of care from oncologists, 70% wanted goals of care to come from oncologists, and 61% best understood and wanted to understand logistics of chemotherapy from oncologists. Sixty-six percent of patients understood adverse effects when they were explained by nursing staff, and 56% wanted explanations of adverse effects to come from nursing staff. Patients did not prefer a specific care team member or information source when receiving financial cost information. Patients often preferred to receive chemotherapy information from their oncologist; however, other members of the care team also provided information to patients in a way that was understood.

The emerging role of lenalidomide in the management of lymphoid malignancies.

Lenalidomide, a novel immunomodulatory drug (IMiD), is a promising therapeutic strategy for patients with relapsed/refractory chronic lymphocytic leukemia (CLL) and B-cell lymphomas. Biologically, the mechanisms responsible for lenalidomide activity are yet to be clearly defined. Based on preclinical models and early correlative studies conducted in parallel to clinical trials, lenalidomide has been found to enhance natural killer (NK)- and T-cell activity against tumor cells, alter the balance of pro- and anti-inflammatory cytokines in the tumor bed, inhibit angiogenesis, and, to a lesser degree, induce cell cycle arrest and apoptosis in cancer cells. Together, all of these biological effects appear to play a role in the activity observed in CLL or lymphoma patients treated with lenalidomide. Given the effect in NK- and T-cell function, lenalidomide is an alternative strategy to enhance the antitumor activity of monoclonal antibodies (mAbs). Clinical responses have been observed in patients with relapsed/refractory CLL, follicular lymphoma, small lymphocytic lymphoma, mantle cell lymphoma (MCL), and diffuse large B-cell lymphoma (DLBCL) treated with lenalidomide single agent. The favorable toxicity profile and route of administration made the use of lenalidomide an attractive therapy for certain types of patients (i.e. elderly, chemotherapy unfit, etc.). The erratic but serious incidence of tumor lysis syndrome and/or tumor flare reactions provides challenges in the incorporation of lenalidomide in the management of previously untreated CLL or CLL/lymphoma patients with bulky adenopathy. Correlative studies and/or retrospective analysis of lenalidomide-treated patients had identified several biomarkers associated with clinical endpoints in CLL (i.e. changes in tumor necrosis factor alpha [TNF-α] or vascular endothelial growth factor [VEGF] levels) or DLBCL (non-GCB phenotype) patients, but need to be validated. Early studies evaluating the efficacy and toxicity of lenalidomide in combination with rituximab in previously untreated indolent lymphoma are promising and warrant further study. In addition, the evaluation of lenalidomide in the maintenance setting or in combination with other target-specific agents (i.e. proteasome inhibitors) in aggressive lymphomas is being addressed in ongoing clinical trials. In summary, lenalidomide is emerging as a biologically active and novel agent in the treatment of B-cell neoplasms. Future translational and clinical studies will further define the role of lenalidomide in the management of de novo or relapsed/refractory CLL or B-cell lymphomas and identify the subset of patients most likely to gain clinical benefit.
