Treatment planning in cutaneous T-Cell lymphoma

DERMATOLOGIC THERAPY, Issue 4 2003
Eric C. Vonderheid
ABSTRACT:, Effective long-term management of cutaneous T-cell lymphoma (CTCL) requires administration of skin-directed therapies such as topically applied nitrogen mustard or photochemotherapy to achieve a complete response in clinically early disease (patch and thin-plaque-phase mycosis fungoides, MF) and often the concomitant administration of well-tolerated drugs with systemic effects such as interferon alfa, bexarotene, methotrexate or extracorporeal photopheresis in more advanced, but not highly aggressive/nontransformed disease (thick plaque or tumor phase MF or erythrodermic CTCL). The author's approach is provided as a guide for dermatologists in private practice. [source]

Cutaneous T-cell lymphoma

ABSTRACT Cutaneous T-cell lymphoma (CTCL) is a neoplasm of helper T cells whose first manifestations usually appear in the skin. The various forms of CTCL are distinguished by both clinical features and histopathology. Early on, the diagnosis may be difficult to establish because of its numerous, and often non-specific, clinical presentations. Further, the pathological findings of early lesions may lack the diagnostic features observed in well-developed or advanced disease. The diagnosis of CTCL must be considered in any patient with a chronic, therapy-resistant condition of the skin. In patients with non-specific histological findings, a high index of suspicion and multiple biopsies may eventually lead to a diagnosis of CTCL. Once the diagnosis of CTCL is established, accurate staging is essential both for its effect on treatment decisions and for its prognostic value. In general, CTCL is a chronic, slowly progressive disease with a long evolution. The development of tumours is a poor prognostic sign, as is erythroderma. The Sezary syndrome is a distinct form of erythrodermic CTCL that is characterized by exfoliative erythroderma, lymphadenopathy, lymphocytosis, intense pruritus, and circulating large, abnormal lymphocytes (Sezary cells). When death does occur, it is most often due to septicemia. Treatment of CTCL must be tailored to the individual patient. The most commonly employed treatment options are photochemotherapy and topical chemotherapy. [source]

Treatment of advanced mycosis fungoides/Sézary syndrome with fludarabine and potential adjunctive benefit to subsequent extracorporeal photochemotherapy

Summary Background Purine analogues [fludarabine monophosphate (FAMP); deoxycoformycin and 2-chlorodeoxyadenosine) and extracorporeal photochemotherapy (ECP) have been suggested to be active agents in advanced cutaneous T-cell lymphoma (CTCL) patients. Objectives To explore further the clinical efficacy and safety of FAMP monochemotherapy in advanced CTCL and to evaluate if the sequential association of ECP to FAMP in selected patients may improve the response rate (RR) and/or lengthen the remission duration. Patients and methods Forty-four CTCL patients [17 Sézary syndrome (SS); 26 mycosis fungoides (MF), stage IIB,IV or with peripheral blood involvement; one MF associated with lymphomatoid papulosis (LyP)] were enrolled in this pilot cohort study. All the patients received FAMP 25 mg m,2 5 days monthly; 19 patients (43·2%) underwent ECP after FAMP was discontinued. The majority of patients with erythrodermic CTCL or peripheral blood involvement underwent the combined FAMP,ECP schedule. Results After a median follow-up of 4·2 years, the overall FAMP RR was 29·5% (13/44); a higher RR was obtained in SS (35·3%) than in MF patients (25·9%). According to the treatment group, the RR of the FAMP,ECP group (63·2%) was significantly higher than that of the FAMP monotherapy group (24%; P = 0·021). No statistically significant difference was found in time-to-progression (TTP) or survival by therapy group, even if the TTP of the patients treated with the FAMP,ECP combination therapy was higher (median 13 vs. 7 months). A decrease or a normalization in the CD4+CD26, circulating subset was observed in responding patients, paralleling the reduction in the circulating Sézary cells. Conclusions FAMP confirms its clinical activity as a single agent in SS; conversely, FAMP results do not compare favourably with other therapeutic approaches for advanced stage MF patients. The sequential association of ECP after FAMP seems to increase the RR, even if future randomized studies are needed to confirm these results. [source]

Extracorporeal photopheresis: what is it and when should it be used?

CLINICAL & EXPERIMENTAL DERMATOLOGY, Issue 7 2009

Summary Extracorporeal photopheresis (ECP) is a technique that was developed > 20 years ago to treat erythrodermic cutaneous T-cell lymphoma (CTCL). The technique involves removal of peripheral blood, separation of the buffy coat, and photoactivation with a photosensitizer and ultraviolet A irradiation before re-infusion of cells. More than 1000 patients with CTCL have been treated with ECP, with response rates of 31,100%. ECP has been used in a number of other conditions, most widely in the treatment of chronic graft-versus-host disease (cGvHD) with response rates of 29,100%. ECP has also been used in several other autoimmune diseases including acute GVHD, solid organ transplant rejection and Crohn's disease, with some success. ECP is a relatively safe procedure, and side-effects are typically mild and transient. Severe reactions including vasovagal syncope or infections are uncommon. This is very valuable in conditions for which alternative treatments are highly toxic. The mechanism of action of ECP remains elusive. ECP produces a number of immunological changes and in some patients produces immune homeostasis with resultant clinical improvement. ECP is available in seven centres in the UK. Experts from all these centres formed an Expert Photopheresis Group and published the UK consensus statement for ECP in 2008. All centres consider patients with erythrodermic CTCL and steroid-refractory cGvHD for treatment. The National Institute for Health and Clinical Excellence endorsed the use of ECP for CTCL and suggested a need for expansion while recommending its use in specialist centres. ECP is safe, effective, and improves quality of life in erythrodermic CTCL and cGvHD, and should be more widely available for these patients. [source]
