ABSTRACT
BACKGROUND: Cutaneous T-cell lymphoma (CTCL), including subtypes mycosis fungoides (MF) and Sézary syndrome (SS), represents a rare group of non-Hodgkin lymphomas. Mogamulizumab is a first-in-class monoclonal antibody that selectively binds to C-C chemokine receptor 4, which is overexpressed on the surface of tumor cells in T-cell malignancies, including MF/SS-type CTCL. OBJECTIVES: This review identifies common diagnostic features of MF/SS, the efficacy and side effect profile of mogamulizumab, and practical management strategies for optimizing the nursing care of patients with MF/SS-type CTCL. METHODS: Case studies are used to describe the role of mogamulizumab in CTCL and to review practical considerations when administering mogamulizumab to patients. FINDINGS: Mogamulizumab is an effective treatment for adult patients with relapsed or refractory MF/SS-type CTCL who have received at least one prior systemic therapy. Infusion reactions and drug eruptions require prompt diagnosis and treatment.

Chronic graft-versus-host disease (cGVHD) continues to be a major complication after allogeneic hematopoietic cell transplantation, significantly affecting patients' quality of life. A regimen of systemic corticosteroids is considered first-line therapy but is often associated with inadequate responses and multiple side effects. In patients with refractory disease, an evidenced-based consensus is lacking as to the single best approach to managing symptoms. Ruxolitinib, a selective JAK1/2 inhibitor, has recently gained favor as a second-line approach in patients with steroid-refractory cGVHD. In this retrospective study, we evaluated the outcomes of 46 patients who received ruxolitinib for cGVHD between March 2016 and December 2017 at our institution, and evaluated ruxolitinib's impact at 6 and 12 months, based on the National Institutes of Health Severity Scale, including organ-specific responses, and mean prednisone dose. Furthermore, we present the first reported probability of ruxolitinib's treatment failure-free survival (FFS) in patients with cGVHD. After 12 months of ruxolitinib therapy, complete response, partial response, and stable disease was observed in 13% (nâ¯=â¯6), 30.4% (nâ¯=â¯14), and 10.9% (nâ¯=â¯5) of patients, respectively. The 1-year probability of FFS was 54.2% (95% confidence interval, .388 to .673), and ruxolitinib use was associated with a reduction in prednisone dose. In conclusion, our data, which represent the largest cohort of patients with cGVHD reported to date, support the use of ruxolitinib for cGVHD refractory to steroids and currently available salvage therapies, discontinued due to lack of response and high cost.
