Background and Objectives: Bexarotene has been approved to treat advanced stage cutaneous T-cell lymphomas (CTCL) since 1999. However, very few data have been published on its long-term safety and efficacy profile. The aim of this study is to determine the tolerability to bexarotene and outcomes by collecting the 2nd largest case series to date on its long-term use vs CTCL., Material and Method: This was a multicenter retrospective review of 216 patients with mycosis fungoides (174), or Sézary syndrome (42) on a 10-year course of bexarotene alone or in combination with other therapies at 19 tertiary referral teaching hospitals., Results: A total of 133 men (62%) and 83 women (38%) were included, with a mean age of 63.5 year (27-95). A total of 45% were on bexarotene monotherapy for the entire study period, 22% started on bexarotene but eventually received an additional therapy, 13% were on another treatment but eventually received bexarotene while the remaining 20% received a combination therapy since the beginning. The median course of treatment was 20.78 months (1-114); and the overall response rate, 70.3%. Complete and partial response rates were achieved in 26% and 45% of the patients, respectively. Treatment was well tolerated, being the most common toxicities hypertriglyceridemia (79%), hypercholesterolemia (71%), and hypothyroidism (52%). No treatment-related grade 5 adverse events were reported., Conclusions: Our study confirms bexarotene is a safe and effective therapy for the long-term treatment of CTCL., (Copyright © 2024 AEDV.

Background and Objective: The cost of treating cutaneous T-cell lymphoma (CTCL) in Spain is unknown. With the advent of new treatments, it is more important than ever to gain an accurate picture of the true costs involved. The MICADOS study had 2 primary objectives: 1)to evaluate the impact of CTCL on patient quality of life, and 2)to evaluate the costs associated with the disease. This article reports the results of the cost analysis., Methods: We estimated the cost of treating CTCL over a period of 1year from the perspective of the Spanish National Health System. Twenty-three dermatologists and hematologists from 15 public hospitals analyzed data for adult patients with mycosis fungoides (MF) or Sézary syndrome (SS)., Results: A total of 141 patients (57.4% male) with a mean age of 63.6 years (95%CI: 61.4-65.7 years) were included. The mean direct annual cost of treating CTCL was €34,214 per patient. The corresponding costs by stage were €11,952.47 for stageI disease, €23,506.21 for stageII disease, €38,771.81 for stageIII disease, and €72,748.84 for stageIV disease. The total direct annual cost of treating MF/SS in public hospitals in Spain was estimated at €78,301,171; stageI disease accounted for 81% of all costs, stageII for 7%, and stagesIII andIV for 6% each., Conclusions: The MICADOS study offers an accurate picture of the direct cost of treating CTCL in patients with MF/SS in Spain and shows that costs vary significantly according to disease stage. Patient-borne and indirect costs should be analyzed in future studies., (Copyright © 2023 AEDV. Publicado por Elsevier España, S.L.U. All rights reserved.)

At the onset of the COVID-19 pandemic, the United States Cutaneous Lymphoma Consortium (USCLC) and the European Organisation for Research and Treatment of Cancer Cutaneous Lymphoma Task Force (EORTC-CLTF) developed emergency guidelines for the management of patients with cutaneous lymphomas (CLs) during the pandemic. These emergency protocols were intended to ensure patient safety and called for dose modifications, treatment delays and treatment interruptions as necessary to minimize exposure risks to COVID-19. Because there are no established maintenance protocols for CLs, the impact of such delays or interruptions on disease outcomes was not known. The ISCL created an International Cutaneous Lymphomas Pandemic Section (ICLYPS) to collect data from the institutions around the world to assess the impact of these changes on patients' outcomes and to determine if these measures were effective in preventing infection. We summarize the outcomes from a preliminary cohort of patients from Brazil, Greece, Italy, Spain, Switzerland, the UK and the US. Actively managed patients with an established diagnosis of CL from March to October 2020 were included according to the Institutional Protection of Human Subjects guidelines at the respective centers. We included 149 patients in this retrospective review. The average age was 61.88 years (range: 22–95). 2 patients (1.3%) had diagnoses of CD30+ lymphoproliferative disorders (LyP and pcALCL), 112 (75.2%) had mycosis fungoides (MF), and 35 (23.5%) had Sézary syndrome (SS). 77 patients (68.7%) had stages IA–IIA MF, 23 (20.5%) had Stage IIB MF, 6 (5.4%) had stage III MF, and 41 (27.5%) had Stage IV disease, of which 6 had Stage IV MF (5.4%) and 35 had SS (23.5%). Treatment was delayed for more than half (53.0%) of the patients for a mean of 3.2 months (range: 10 days to 10 months). Treatment delay was associated with a significant risk of disease relapse or progression across all stages (65.8% vs 32.9%, p<0.00001). During follow up, 6 patients (4%) died due to disease progression, including 3 patients with Stage IIB MF, one with Stage IVB MF, and two with SS. Twenty-eight patients (18.8%) had a confirmed COVID-19 infection during the capture period. Two of these cases were definitive hospital-acquired infections following prolonged hospital admission, while the remaining contracted the virus through community exposures. There were no outpatient office-acquired infections. Three of the 26 patients who contracted COVID-19 died of the infection (2 SS and 1 LyP, mean age: 80, range: 66–89). The ICLYPS analysis has revealed that treatment interruptions and delays during the COVID-19 pandemic resulted in significantly worse outcomes in patients with CLs as compared to those who did not experience treatment interruptions. No outpatient office-acquired infections were reported in this extensive review, and patients with CLs who developed COVID-19 did not do worse than expected according to their risk factors. Effective safety measures and protocols can prevent transmission of COVID-19 at physicians' offices. Interruption of therapy leads to negative clinical outcomes and should be avoided, especially in the setting of advanced disease, as the risk of contracting COVID-19 in the outpatient setting did not outweigh the risk of morbidity and mortality due to disease progression. Ensuring continuity of treatment and maintenance therapy appears to be critical to avoiding life-threatening disease progression. [ABSTRACT FROM AUTHOR]

Background: Advanced-stage mycosis fungoides/Sézary syndrome (aMF/SS) has a dismal outcome. The only curative treatment is allogeneic stem cell transplantation (allo-SCT) but this is limited to selected candidates, thus palliative therapy is the most frequent strategy., Objectives: To describe the characteristics of aMF/SS in cases referred to haematology units for advanced/palliative therapy., Materials and Methods: Data from 30 patients were collected from four centres, and descriptive statistics, frequencies and survival analyses were calculated., Results: Eighty-eight per cent of patients received systemic therapy. The median number of therapies was three (range: 1-9). Bexarotene (21%), CHOP-like chemotherapy (10%) and methotrexate (9%) were the more common treatments. The overall survival at a median follow-up of 28 months (range: 8-65 months) for aMF/SS was 56.9%. Survival probability was more favourable for MF (p < 0.02). Nine patients received allo-SCT. Half of the patients (56%) relapsed after allo-SCT but could be rescued with immunosuppression tapering, donor lymphocyte infusions and additional therapy (80%)., Conclusion: There is significant heterogeneity in aMF/SS treatments. Survival is more favourable for MF compared to SS. Current chemoimmunotherapies are insufficient to control disease, making allo-SCT the best therapeutic approach in selected patients.
