International study of treatment efficacy in SS shows superiority of combination therapy and heterogeneity of treatment strategies. Blood Adv 2023; 7:6639-6647. [PMID: 37648672 PMCID: PMC10628811 DOI: 10.1182/bloodadvances.2023011041] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2023] [Revised: 08/22/2023] [Accepted: 08/22/2023] [Indexed: 09/01/2023] Open
Abstract
Despite increasing availability of therapies, patients with Sezary syndrome (SS) commonly endure multi-line treatment journeys, mostly with partial responses of short duration. Measuring clinical benefit is challenging; time-to-next-treatment (TTNT) provides a robust, objective measurement of efficacy. This international observational study examines patterns of clinical care and therapeutic benefit as measured by TTNT. TTNT was calculated for monotherapies and combination therapies, with consideration to treatment line. 178 patients with SS (73% de novo, 27% secondary) were included, receiving 721 lines of systemic therapy, with median follow-up of 56.9 months. Across all lines, 58 different therapeutic regimens were prescribed (54 were systemic therapies) and classified into 17 treatment groups. The most common first-line treatments were extracorporeal photopheresis (ECP)-containing combination therapy (20%) and retinoid monotherapy (19%). Median TTNT for all first-line therapies was short (5.4 months). First-line, combination therapies had longer median TTNT than monotherapies, 10.0 vs 5.0 months (P = .004), respectively. Later delivery of combination therapies was associated with shorter clinical benefit, with median TTNT reduced to 6.2 and 2.2 months for mid-line (2nd-4th line) and late-line (≥5th line), respectively (P < .001). First-line ECP-containing treatments were associated with longer median TTNT than non-ECP-containing treatments, 9.0 vs 4.9 months (P = .007). For both ECP-monotherapy and ECP-containing combination therapy, significant reductions in TTNT were seen in later lines. These data suggest therapeutic benefit from first-line delivery of combination therapy for SS and favor early inclusion of ECP in the treatment algorithm for those who can access it.

Abstract
Mycosis fungoides (MF) and Sézary syndrome (SS) are cutaneous T-cell lymphomas. MF is the most common cutaneous lymphoma, and it is classified into classic Alibert-Bazin MF, folliculotropic MF, pagetoid reticulosis, and granulomatous slack skin, each with characteristic clinical presentation, histopathological findings, and distinct clinical behaviors. SS is an aggressive leukemic variant of cutaneous lymphoma, and it is characterized by erythroderma, lymphadenopathy, and peripheral blood involvement by malignant cells. There is a wide range of dermatological manifestations of MF/SS, and prompt recognition is essential for early diagnosis. Skin biopsy for histopathology and immunohistochemical analysis is imperative to confirm the diagnosis of MF/SS. Histopathology may also provide information that may influence prognosis and treatment. Staging follows the TNMB system. Besides advanced stage, other factors associated with poorer prognosis are advanced age, male gender, folliculotropism in histopathology of patients with infiltrated plaques and tumors in the head and neck region, large cell transformation, and elevated lactate dehydrogenase. Treatment is divided into skin-directed therapies (topical treatments, phototherapy, radiotherapy), and systemic therapies (biological response modifiers, targeted therapies, chemotherapy). Allogeneic bone marrow transplantation and extracorporeal photopheresis are other treatment modalities used in selected cases. This review discusses the main clinical characteristics, the histopathological/immunohistochemical findings, the staging system, and the therapeutic management of MF/SS.

Cost-Effectiveness of Extracorporeal Photopheresis for the Treatment of Patients With Erythrodermic (Stage T 4, M 0) Cutaneous T-Cell Lymphoma in the Australian Setting. VALUE IN HEALTH : THE JOURNAL OF THE INTERNATIONAL SOCIETY FOR PHARMACOECONOMICS AND OUTCOMES RESEARCH 2022; 25:965-974. [PMID: 35667784 DOI: 10.1016/j.jval.2021.11.1364] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Revised: 10/19/2021] [Accepted: 11/10/2021] [Indexed: 06/15/2023]
Abstract
OBJECTIVES Cutaneous T-cell lymphoma (CTCL) is a rare and incurable disease, and patients currently experience a lack of treatment options in Australia. This analysis evaluated the cost-effectiveness of extracorporeal photopheresis (ECP) compared with standard of care therapy for the treatment of patients with erythrodermic (stage T4, M0) CTCL, who are refractory to previous systemic treatment. METHODS A Markov model was developed from the perspective of the Australian government. Health states were treatment specific and transition probabilities were modeled from time-to-next-treatment data from a published Australian observational study of ECP and comparator treatments. Quality of life utility values were based on psoriasis as a proxy for CTCL, which was validated by consultation with local clinicians. The time horizon for the model was 5 years. The ECP treatment regimen was compared with a weighted treatment comparator based on results of a treatment survey and Australian prescribing data. RESULTS ECP as a second-line treatment option for CTCL was less costly and more effective than other treatment strategies. ECP had an average cost saving of $37 592 and incremental quality-adjusted life-year gained of 0.20 to 0.21, attributed to patients being able to better tolerate ECP thus avoiding subsequent treatment with high-cost alternatives. CONCLUSIONS This is the first published cost-utility analysis of ECP for CTCL. This analysis demonstrates that ECP is a cost-effective option for the treatment of patients with erythrodermic CTCL in Australia.

Abstract
BACKGROUND Mycosis fungoides and Sézary syndrome are the most common non-Hodgkin lymphomas that manifest primarily in the skin. Although early-stage disease has an excellent long-term survival rate, advanced disease carries a poor survival rate. Given the lengthy and complex clinical course, nurses are at the forefront of education and supportive care management for patients and caregivers. OBJECTIVES This article aims to provide an overview of mycosis fungoides and Sézary syndrome and to highlight practice considerations for optimal nursing care. METHODS Clinical presentation, diagnosis, management, and nursing consideration are discussed. FINDINGS Oncology nurses have a vital role in educating patients and their caregivers about the side effects of cancer treatment, appropriate skin care, and infection risk.
