Evaluación de los costes asociados a la enfermedad de pacientes con linfoma cutáneo de células T en España: análisis en función del estadio clínico (estudio MICADOS) / Cost of Treating Cutaneous T-Cell Lymphoma in Spain: Analysis of MICADOS Study Data by Disease Stage

Antecedentes y objetivo No se dispone de datos españoles sobre el coste asociado al linfoma cutáneo de célulasT (LCCT). Además, la incorporación de nuevos tratamientos hace necesario analizar el coste real de la enfermedad. El estudio MICADOS analizó dos objetivos principales: Por un lado, evaluó el impacto en la calidad de vida en los pacientes con LCCT, y por otro lado, estudió los costes de la enfermedad. En esta publicación se recoge el segundo de los objetivos del estudio. Métodos El coste de la enfermedad se estudió bajo la perspectiva del Sistema Nacional de Salud (SNS) con un horizonte temporal de un año. Participaron 23 dermatólogos y hematólogos de 15 hospitales públicos españoles. Se incluyeron pacientes adultos con LCCT del tipo micosis fungoide (MF) y síndrome de Sézary (SS). Resultados Se incluyeron 141 pacientes, el 57,4% masculinos, con una edad media de 63,6 años (IC95%: 61,4-65,7). Los costes directos anuales medios por pacientes del estudio fueron de 34.214€, siendo de 11.952,47€ en estadioI, 23.506,21€ en estadioII, 38.771,81€ en estadioIII y 72.748,84€ en estadioIV. El coste anual directo total estimado de todos los pacientes en España con MF/SS resultó en 78.301.171€, donde el 81% de los costes fueron atribuibles a pacientes en estadioI, el 7% al estadioII, el 6% al estadioIII y el 6% al estadioIV. Conclusiones Este estudio ofrece una evaluación precisa del coste directo del LCCT en pacientes con MF/SS en España, mostrando costes que varían sustancialmente en función del estadio. Los costes soportados por el paciente y los costes indirectos deberán considerarse en futuras investigaciones (AU)

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 (AU)

The changing therapeutic landscape, burden of disease, and unmet needs in patients with cutaneous T-cell lymphoma.

Cutaneous T-cell lymphomas (CTCLs) have a chronic, relapsing course, and the most common subtypes are mycosis fungoides and Sézary syndrome. The disease causes visible skin alterations and can also cause alopecia, pruritus and pain, all of which can impact patients' health-related quality of life (HRQoL). The goal of treatment is to reduce symptoms and prevent disease progression. However, treatment recommendations are often based on low levels of evidence due to the lack of well-designed randomised clinical trials and treatment guidelines, and approved drugs vary considerably across different countries and regions. Currently, available treatments rarely lead to durable remissions and eventually become less effective, meaning patients often require multiple therapy changes. Skin-directed therapies (SDTs) are first-line treatments for early-stage CTCL, whereas systemic therapies may be needed for early-stage disease that does not respond to SDT or for advanced-stage disease. However, patients can experience significant side-effects with these treatments or may be unable to tolerate them. Hence, there is an unmet need for effective therapies with good safety profiles for the treatment of early- and late-stage CTCL. Here, we review current treatment guidelines, investigational and approved treatments, the impact of CTCL on patients' HRQoL, and the treatment of pruritus.

Healthcare resource utilization, costs of care, and treatment of mycosis fungoides cutaneous T-cell lymphoma patterns in a large managed care population: a retrospective US claims-based analysis.

PURPOSE: To evaluate health care utilization, treatment patterns and costs among patients with mycosis fungoides-cutaneous T-cell lymphoma (MF-CTCL). METHODS: This retrospective cohort study queried the HealthCore Integrated Research Database to identify patients ≥18 years with ≥2 diagnoses of MF-CTCL (ICD-9-CM code 202.1x, 202.2x) between 07 January 2006 and 07 January 2013. Index date was defined as first MF-CTCL diagnosis. Patients were continuously enrolled ≥6 months before and ≥12 months after index date. Severe MF-CTCL was identified via systemic therapy use postindex. Generalized linear model (GLM) was used to estimate the relationship between MF-CTCL severity and healthcare costs controlling for selected factors. RESULTS: A total of 1981 MF-CTCL patients were evaluated: 493 (24.9%) severe and 1488 (75.1%) with mild to moderate disease. GLM analysis indicated severe MF-CTCL patients incurred higher all-cause healthcare total costs compared to patients with mild-to-moderate MF-CTCL (coefficient estimate: 4.19, p < .0001). About 51% of patients did not receive any MF-CTCL-specific treatment within 60 days after MF-CTCL diagnosis. CONCLUSIONS: MF-CTCL severity was associated with greater healthcare resource utilization and costs. These findings suggest that about half of MF-CTCL patients do not receive MF-CTCL-specific treatment within 60 days following initial diagnosis. Future studies are needed to understand reasons for delayed treatment initiation.

An exploratory cost-effectiveness analysis of systemic treatments for cutaneous T-cell lymphoma.

PURPOSE: To conduct an exploratory cost-effectiveness analysis of systemic treatment options for more advanced cutaneous T-cell lymphoma (CTCL). METHODS: A cost-effectiveness model compared systemic bexarotene, denileukin diftitox, interferon-α, methotrexate, pralatrexate, romidepsin, vorinostat, and extracorporeal photopheresis (ECP) treatment of CTCL. Treatment effectiveness data were extracted from published studies and/or US product labeling. Overall response, the primary effectiveness measure, was defined as the proportion of patients achieving complete or partial response. Costs were based on wholesale acquisition cost (medications) and Medicare reimbursement rates (ECP, medication administration, adverse drug effect treatment). The perspective of the study was from that of a payer. RESULTS: Methotrexate was the lowest cost option [mean $436; standard deviation (SD) $284], followed by interferon-α (mean $32,174; SD $27,582), denileukin difitox (mean $40,107; SD $18,598), and ECP (mean $40,985; SD $45,633). Other treatments had costs greater than $50,000, ranging from vorinostat ($65,958; SD $40,637) to bexarotene ($239,424; SD $178,881). The incremental cost-effectiveness ratio per successfully treated patient was $396,725 (interferon) and $213,416 (ECP). Denileukin diftitox, romidepsin, and vorinostat were less effective and cost more than methotrexate. CONCLUSION: Methotrexate is the most cost-effective option for CTCL; however, its low cost is offset by its limited effectiveness in advanced stages of CTCL. ECP and interferon appear the next most cost-effective therapies.

Assessing clinical outcomes in cutaneous T-cell lymphoma.

It is apparent that multiple end points are required to adequately describe the response to therapy for CTCL. Investigators may differ as to which end points are best suited for their data. In general, multiple end points provide a better overall view of response to treatment as compared with a single end point. Regardless, measures of response and end points should be clearly defined and the methods of calculating end points clearly stated.
