Impact of electronic interventions on guideline concordant ordering of rituximab infusion rate.

Introduction: Rituximab carries a boxed warning for severe or fatal infusion reactions; most occurring with the initial infusion. Prior studies established that if the initial rituximab infusion is tolerated, subsequent infusions can be given safely over 90 min. The University of Chicago Medicine (UCM) did not have a standardized method to document infusion reactions for outpatient chemotherapy patients, making it challenging for providers to know a patients' eligibility for rapid infusion.

Implementation of pharmacogenomic testing in oncology care (PhOCus): study protocol of a pragmatic, randomized clinical trial.

Background: Many cancer patients who receive chemotherapy experience adverse drug effects. Pharmacogenomics (PGx) has promise to personalize chemotherapy drug dosing to maximize efficacy and safety. Fluoropyrimidines and irinotecan have well-known germline PGx associations.

Changes in Intravenous Immunoglobulin Usage for Hypogammaglobulinemia After Implementation of a Stewardship Program.

Purpose: Intravenous immunoglobulin (IVIG) is used to replenish immunoglobulins in hypogammaglobulinemia (HG) caused by hematologic malignancies (HM) or their treatment (autologous stem-cell transplantation [ASCT] and chimeric antigen receptor T-cell therapy [CAR-T]), in an effort to reduce the risk of infections. However, there is limited evidence to support this use, and IVIG supplies are limited and shortages are common.

Methods: An IVIG stewardship program (ISP) was implemented with the following requirements for IVIG administration: immunoglobulin G (IgG) level < 400 mg/dL (corrected for paraprotein) for post-ASCT and post-CAR-T patients, or IgG < 400 mg/dL with a history of a bacterial infection within the preceding 3 months for those with HM.

HIPEC with cisplatin in a patient with a prior hypersensitivity reaction to systemic oxaliplatin.

Platinum-based chemotherapeutic agents are commonly used in the treatment of several cancers. While effective, they are often discontinued due to toxicities and hypersensitivity reactions (HSRs) that occur more frequently with repeated exposure. Following discontinuation of one agent, therapy may be continued with a second platinum salt, though the cross-reactivity between agents in this class is not well understood.

Impact of an Oncology Clinical Pharmacist Specialist in an Outpatient Multiple Myeloma Clinic.

Introduction: Improvements in cancer treatment and supportive care, as well as the approval of oral chemotherapy medications over the past decade, have resulted in an increasing number of cancer patients being treated in outpatient settings. Transitioning cancer treatments to the outpatient setting places greater emphasis on proper medication counseling and optimal management of adverse effects. We therefore evaluated the clinical and financial impact of an oncology clinical pharmacist specialist in an interdisciplinary multiple myeloma clinic by using a validated scoring tool.

The impact of initiating posaconazole on tacrolimus pharmacokinetics in allogeneic stem cell transplantation.

Background: Posaconazole reduces the risk of invasive Aspergillus in transplant patients, but significantly inhibits tacrolimus metabolism. One study demonstrated that a three-fold dose reduction of tacrolimus was required to obtain therapeutic concentrations when used with posaconazole. However, with empiric dose reduction, there is a risk of subtherapeutic tacrolimus levels and subsequent graft failure or graft-versus-host disease.

Pharmacy Operationalization of the Intralesional Oncolytic Immunotherapy Talimogene Laherparepvec.

Oncolytic immunotherapy involves the use of viruses to target and destroy cancer cells and to induce immune responses for an enhanced antitumor effect. Talimogene laherparepvec, a genetically modified herpes simplex virus type 1 (HSV-1) that selectively replicates in tumors to induce lytic cell death, tumor antigen release, and the local production of granulocyte-macrophage colony-stimulating factor (GM-CSF), has been approved for the treatment of a defined population of patients with metastatic melanoma. Talimogene laherparepvec is administered as a series of intralesional injections, and specific procedures are implemented to minimize the risk of viral exposure.

Biosimilars in Oncology in the United States: A Review.

Importance: Biosimilars are biological medicines that contain a highly similar version of the active substance of an already approved biologic reference product. The availability of biosimilars might provide an opportunity to lower health care expenditures as a result of the inherent price competition with their reference product. Understanding how biosimilar cancer drugs are regulated, approved, and paid for, as well as their impact in a value-based care environment, is essential for physicians and other stakeholders in oncology.

Impact of a clinical pathway on appropriate empiric vancomycin use in cancer patients with febrile neutropenia.

Objectives Febrile neutropenia management guidelines recommend the use of vancomycin as part of an empiric antimicrobial regimen when specific criteria are met. Often, vancomycin use among patients with febrile neutropenia is not indicated and may be over utilized for this indication. We sought to evaluate the impact of implementing a febrile neutropenia clinical pathway on empiric vancomycin use for febrile neutropenia and to identify predictors of vancomycin use when not indicated.

BK virus infection is associated with hematuria and renal impairment in recipients of allogeneic hematopoetic stem cell transplants.

BK virus (BKV) is an important pathogen and cause of nephropathy in renal transplant recipients, but its significance following hematopoetic stem cell transplantation (HSCT) is less well described. We measured blood and urine BKV in 124 allogeneic HSCT patients (67 had undergone prior HSCT [surveillance cohort]; 57 were monitored from transplant day 0 [prospective cohort]). BK viruria was manifest in 64.
