    Study Notes

    Mycosis Fungoides (MF) and Sézary Syndrome (SS) Overview

    • Mycosis fungoides (MF) can exhibit few tumors with variable body surface area (BSA) leading to a clinician's paradox in prognosis assessment.
    • The Modified Severity Weighted Assessment Tool (mSWAT) enhances BSA evaluation by integrating skin, lymph node, and blood conditions to better correlate with prognosis.
    • Sézary syndrome (SS) patients are at increased risk for infections, necessitating routine checks for peripheral blood involvement and diagnostic biopsies.

    Treatment Insights

    • Brentuximab vedotin is notable for targeting CD30 in patients with CD30-positive MF, showing significant efficacy in those previously treated.
    • Various treatments are categorized into early-stage and advanced-stage options; recommended treatments include specific drugs based on disease stage and prior therapies.

    Clinical Features and Prognosis

    • Advanced-stage primary cutaneous anaplastic large-cell lymphoma (pcALCL) has a 5-year survival rate of 77%, demonstrating that even skin lymphomas can show a range of outcomes based on their stage.
    • Common clinical features of SS include erythroderma, pruritus, and lichenification, often resembling inflammatory skin conditions.

    Treatment Modalities and Outcomes

    • Narrow-band UVB therapy reported an average response rate of 87.6% with a complete response (CR) of 62.2%.
    • PUVA therapy showed a CR rate of up to 73.8%, indicating strong efficacy, especially in early-stage treatment.
    • The combination of PUVA with interferon alpha-2a resulted in significantly shorter time to CR compared to monotherapy with acitretin and interferon.
    • Bexarotene has been recognized for its efficacy, yielding a response rate between 45-67% across various trials for early and advanced stages.

    Monitoring and Development of Drug Candidates

    • Evaluating T-cell receptor (TCR) clonality forms part of the diagnostic work-up, essential for treatment stratification.
    • Emerging drug candidates like mogamulizumab and romidepsin target preferential expression on malignant T cell populations to improve quality of life by alleviating symptoms of pruritus.
    • CD30 and CCR4 are potential targets as they demonstrate selective expression on malignant cutaneous T-cell populations, paving the way for monoclonal antibody therapies.

    Treatment Response Rates

    • Treatments deliver variable response rates, with Extracorporeal Photopheresis (ECP) demonstrating a 63% median response rate across major studies, indicating its role in managing symptomatic erythrodermic MF.
    • Overall response rates for various agents are summarized, noting distinctions in drug effectiveness and duration of response (mDOR) across treatment modalities for MF and SS.

    Research Directions

    • The ongoing identification of biomarkers and genetic alterations in MF, such as CDKN2A/CDKN2B deletions, aids in categorizing aggressive tumor subsets.
    • Newer approaches to characterizing immunophenotypes might improve the understanding of clinical behaviors in CTCL and assist optimal treatment designs.
