Long term outcomes of nonmyeloablative allogeneic stem cell transplantation with TSEB TLI and ATG for Mycosis Fungoides and Sezary Syndrome.

Advanced stage (IIB-IVB) Mycosis Fungoides (MF) and Sezary Syndrome (SS) have a poor prognosis with median survival <5 years. We report long-term outcomes of a non-myeloablative allogeneic stem cell transplantation regimen consisting of total skin electron beam therapy, total lymphoid irradiation and antithymocyte globulin. Our prospective cohort consisted of 41 patients with a higher proportion of MF (34MF, 7SS). Acute GVHD Grade 2 to 4 was seen in 31.7% and chronic GVHD Grade 2 to 4 in 24%. The cumulative incidence of non-relapse mortality was 9.8% at 1 year and 12.6% at 2 years. At Day +90 post-transplant 66% of patients had a complete response (CR). With a median post-transplant follow up of 5.27 years, the 5-year overall survival rate was 37.7% (MF 36.7%, SS 57.1%). The 5-year cumulative incidence of progressive disease or relapse was 52.7% in all patients but only 20.8% in those with CR at transplant compared to 70.6% in those not in CR at transplant (p = 0.006). Long term survival is possible in advanced MF and SS with non-myeloablative transplantation and outcomes are improved in patients with CR at transplant.

European dermatology forum: Updated guidelines on the use of extracorporeal photopheresis 2020 - Part 2.

BACKGROUND: Following the first investigational study on the use of extracorporeal photopheresis for the treatment of cutaneous T-cell lymphoma published in 1983, this technology has received continued use and further recognition for additional earlier as well as refractory forms. After the publication of the first guidelines for this technology in the JEADV in 2014, this technology has maintained additional promise in the treatment of other severe and refractory conditions in a multidisciplinary setting. It has confirmed recognition in well-known documented conditions such as graft-vs.-host disease after allogeneic bone marrow transplantation, systemic sclerosis, solid organ transplant rejection including lung, heart and liver and to a lesser extent inflammatory bowel disease. MATERIALS AND METHODS: In order to further provide recognized expert practical guidelines for the use of this technology for all indications, the European Dermatology Forum (EDF) again proceeded to address these questions in the hands of the recognized experts within and outside the field of dermatology. This was done using the recognized and approved guidelines of EDF for this task. All authors had the opportunity to review each contribution as it was added. RESULTS AND CONCLUSION: These updated 2020 guidelines provide at present the most comprehensive available expert recommendations for the use of extracorporeal photopheresis based on the available published literature and expert consensus opinion. The guidelines were divided into two parts: PART I covers Cutaneous T-cell lymphoma, chronic graft-vs.-host disease and acute graft-vs.-host disease, while PART II will cover scleroderma, solid organ transplantation, Crohn's disease, use of ECP in paediatric patients, atopic dermatitis, type 1 diabetes, pemphigus, epidermolysis bullosa acquisita and erosive oral lichen planus.

The PROCLIPI international registry of early-stage mycosis fungoides identifies substantial diagnostic delay in most patients.

BACKGROUND: Survival in mycosis fungoides (MF) is varied and may be poor. The PROCLIPI (PROspective Cutaneous Lymphoma International Prognostic Index) study is a web-based data collection system for early-stage MF with legal data-sharing agreements permitting international collaboration in a rare cancer with complex pathology. Clinicopathological data must be 100% complete and in-built intelligence in the database system ensures accurate staging. OBJECTIVES: To develop a prognostic index for MF. METHODS: Predefined datasets for clinical, haematological, radiological, immunohistochemical, genotypic, treatment and quality of life are collected at first diagnosis of MF and annually to test against survival. Biobanked tissue samples are recorded within a Federated Biobank for translational studies. RESULTS: In total, 430 patients were enrolled from 29 centres in 15 countries spanning five continents. Altogether, 348 were confirmed as having early-stage MF at central review. The majority had classical MF (81·6%) with a CD4 phenotype (88·2%). Folliculotropic MF was diagnosed in 17·8%. Most presented with stage I (IA: 49·4%; IB: 42·8%), but 7·8% presented with enlarged lymph nodes (stage IIA). A diagnostic delay between first symptom development and initial diagnosis was frequent [85·6%; median delay 36 months (interquartile range 12-90)]. This highlights the difficulties in accurate diagnosis, which includes lack of a singular diagnostic test for MF. CONCLUSIONS: This confirmed early-stage MF cohort is being followed-up to identify prognostic factors, which may allow better management and improve survival by identifying patients at risk of disease progression. This study design is a useful model for collaboration in other rare diseases, especially where pathological diagnosis can be complex.

'It's a traumatic illness, traumatic to witness': a qualitative study of the experiences of bereaved family caregivers of patients with cutaneous T-cell lymphoma.

BACKGROUND: Cutaneous T-cell lymphomas (CTCL) are rare cancers, which can be difficult to diagnose, are incurable and adversely affect quality of life, particularly in advanced disease. Families often provide care, but little is known about their experiences or needs while caring for their relative with advanced disease or in bereavement. OBJECTIVES: To explore the experiences of bereaved family caregivers of patients with CTCL. METHODS: Single, semi-structured qualitative interviews were conducted with bereaved family caregivers of patients with CTCL recruited via a supra-regional CTCL clinic. Transcribed interviews were analysed thematically, focusing on advanced disease, the approach of death and bereavement. RESULTS: Fifteen carers of 11 deceased patients participated. Experiences clustered under four themes: (1) complexity of care and medical intervention; (2) caregiver roles in advanced CTCL; (3) person-centred vs. organization-centred care in advanced CTCL and (4) knowing and not knowing: reflections on dying, death and bereavement. Caregivers often had vivid recollections of the challenges of caring for their relative with advanced CTCL and some took on quasi-professional roles as a result. Advanced disease made high demands on both organizational flexibility and family resources. For many caregivers, seeing disease progression was a prolonged and profoundly traumatic experience. The extent to which they were prepared for their relative's death and supported in bereavement was highly variable. Sub-themes within each theme provide more detail about caregiver experiences. CONCLUSIONS: Family caregivers should be considered part of the wider healthcare team, acknowledging their multiple roles and the challenges they encounter in looking after their relative with CTCL as the disease progresses. Their experiences highlight the importance of organizational flexibility and of good communication between healthcare providers in advanced CTCL.

Global patterns of care in advanced stage mycosis fungoides/Sezary syndrome: a multicenter retrospective follow-up study from the Cutaneous Lymphoma International Consortium.

BACKGROUND: Advanced-stage mycosis fungoides (MF)/Sézary syndrome (SS) patients are weighted by an unfavorable prognosis and share an unmet clinical need of effective treatments. International guidelines are available detailing treatment options for the different stages but without recommending treatments in any particular order due to lack of comparative trials. The aims of this second CLIC study were to retrospectively analyze the pattern of care worldwide for advanced-stage MF/SS patients, the distribution of treatments according to geographical areas (USA versus non-USA), and whether the heterogeneity of approaches has potential impact on survival. PATIENTS AND METHODS: This study included 853 patients from 21 specialist centers (14 European, 4 USA, 1 each Australian, Brazilian, and Japanese). RESULTS: Heterogeneity of treatment approaches was found, with up to 24 different modalities or combinations used as first-line and 36% of patients receiving four or more treatments. Stage IIB disease was most frequently treated by total-skin-electron-beam radiotherapy, bexarotene and gemcitabine; erythrodermic and SS patients by extracorporeal photochemotherapy, and stage IVA2 by polychemotherapy. Significant differences were found between USA and non-USA centers, with bexarotene, photopheresis and histone deacetylase inhibitors most frequently prescribed for first-line treatment in USA while phototherapy, interferon, chlorambucil and gemcitabine in non-USA centers. These differences did not significantly impact on survival. However, when considering death and therapy change as competing risk events and the impact of first treatment line on both events, both monochemotherapy (SHR = 2.07) and polychemotherapy (SHR = 1.69) showed elevated relative risks. CONCLUSION: This large multicenter retrospective study shows that there exist a large treatment heterogeneity in advanced MF/SS and differences between USA and non-USA centers but these were not related to survival, while our data reveal that chemotherapy as first treatment is associated with a higher risk of death and/or change of therapy and thus other therapeutic options should be preferable as first treatment approach.

Phase II multicentre trial of oral quisinostat, a histone deacetylase inhibitor, in patients with previously treated stage IB-IVA mycosis fungoides/Sézary syndrome.

BACKGROUND: Quisinostat is a hydroxamate, second-generation, orally available pan-histone deacetylase inhibitor. OBJECTIVES: To evaluate the efficacy and safety of oral quisinostat in patients with previously treated cutaneous T-cell lymphoma (CTCL). METHODS: Patients received quisinostat 8 mg or 12 mg on days 1, 3 and 5 of each week in 21-day treatment cycles. Primary efficacy end point was cutaneous response rate (RR) based on the modified Severity Weighted Assessment Tool (mSWAT). Secondary end points included global RR, duration of response (DOR) in skin, progression-free survival (PFS), pruritus relief, safety and pharmacodynamic markers. RESULTS: Eight of 26 (25 evaluable) patients achieved ≥ 50% reduction in mSWAT score at least once, with confirmed cutaneous response in six (RR 24%). There was a low global RR of 8%. DOR in skin ranged from 2·8 to 6·9 months. Median PFS was 5·1 months. Pruritus relief was more frequent in cutaneous responders (67%) than nonresponders (32%). Serial tumour biopsies revealed an increase in acetylated tubulin, indicating a target effect of histone deacetylase 6. Twenty-one of 26 (81%) patients were withdrawn from the study before or at clinical cut-off; five (19%) continued to receive treatment with quisinostat. The most common drug-related adverse events were nausea, diarrhoea, asthenia, hypertension, thrombocytopenia and vomiting. Grade 3 drug-related adverse events included hypertension, lethargy, pruritus, chills, hyperkalaemia and pyrexia. CONCLUSIONS: Quisinostat 12 mg three times weekly is active in the treatment of patients with relapsed or refractory CTCL, with an acceptable safety profile. Combination therapy with other drugs active in CTCL may be appropriate.

'We had to change to single beds because I itch in the night': a qualitative study of the experiences, attitudes and approaches to coping of patients with cutaneous T-cell lymphoma.

BACKGROUND: Primary cutaneous T-cell lymphoma (CTCL) is a rare but prevalent condition which can have a significant impact on many aspects of quality of life. However, there is little evidence of patients' lived experience of CTCL. OBJECTIVES: To understand in greater depth patients' experiences of living and coping with CTCL, and to inform the development of models of care for this population in line with U.K. METHODS: Semi-structured interviews were conducted with a purposive sample of patients with CTCL who attended an inner-city teaching hospital. Participants were purposively selected according to their disease stage, age, sex and ethnicity. RESULTS: Nineteen patients with CTCL (stages IB-IVB), aged between 41 and 83 years, participated in a single interview. This included 10 men; 15 people identified themselves as white British. Interviews lasted a median of 55 (range 28-170) min. Two main themes emerged: issues regarding diagnosis, particularly a perceived delay in diagnosis, and the impact of CTCL (subthemes related to physical well-being, practical concerns and psychological and social well-being and coping). CONCLUSIONS: Findings from this study illuminate the diverse effects of CTCL on patients' lives. The universal experience of delays in diagnosis was striking and a concern to patients. The disease, particularly its physical symptoms, had a significant impact on patients' lives, including employment, leisure and relationships. Despite the symptom burden and its impact, participants described effective coping strategies such as drawing on social support, maintaining normal lives and becoming well informed about CTCL. Proactive holistic assessment and management of the range of patient concerns is needed in providing care for patients with CTCL and their family and friends.

'We're all carrying a burden that we're not sharing': a qualitative study of the impact of cutaneous T-cell lymphoma on the family.

BACKGROUND: Cutaneous T-cell lymphoma (CTCL) is a rare, progressive cancer that can be life limiting and highly disfiguring. Patients with CTCL experience poor quality of life; however, there is little published about the experiences of their families. OBJECTIVES: To describe the impact of CTCL on family members and how they cope and adjust, to inform support services. METHODS: Semistructured qualitative interviews were conducted with adult informal caregivers of patients with CTCL recruited via a supraregional CTCL clinic. Interviews explored the history of each patient's illness, the impact of CTCL on the patient and the family, and views about family support. Data were analysed thematically using the Family Adjustment and Adaptation Response model as an interpretative framework. RESULTS: Fourteen caregivers were interviewed (11 spouses, one friend, two daughters; 10 women, four men; all white British; aged 39-85 years). Three key themes emerged: (i) demands of CTCL (the disease, caregiving, financial impact, physical and emotional intimacy); (ii) family capabilities (family support, information, healthcare provider support, other coping strategies); and (iii) adjustment and adaptation (acceptance, changes in patient-caregiver relationship and family dynamics). CTCL was central in many aspects of caregivers' lives, particularly relationships, communication and intimacy. CONCLUSIONS: Our findings demonstrate the multiple demands that CTCL places on caregivers, the capabilities and resources they draw upon to cope, and the significant impact of CTCL on the family. To support families and patients, easily accessible services are needed that include the family in the unit of care, provide support and information, and understand the process of family adjustment and adaptation.

Management of paediatric tuberculosis in leading UK centres: unveiling consensus and discrepancies.

SETTING: Large specialist paediatric TB clinics in the UK. OBJECTIVE: To evaluate clinical practice and compare with national and international guidelines. DESIGN: A survey based on an electronic questionnaire on the management of latent tuberculous infection (LTBI) and tuberculosis (TB) disease was conducted in 13 specialist paediatric TB clinics. The consensus and discrepancies were evaluated by descriptive analysis. RESULTS: Practice was reportedly different when choosing age limits for preventive treatment for TB contacts with initially negative tuberculin skin tests (TSTs), interpretation of TST results and use of interferon-gamma release assays (IGRAs) in the context of LTBI. In relation to management of children with TB disease, practices varied for duration of treatment of osteoarticular TB, monitoring for ethambutol ocular toxicity and use of pyridoxine. There was limited experience with multidrug-resistant TB (MDR-TB), and over half of the clinics monitored MDR-TB contacts without giving preventive treatment. CONCLUSIONS: The survey showed heterogeneity in several aspects of clinical care for children with TB. Available paediatric TB guidelines differ substantially, explaining the wide variations in management of childhood TB. Prospective paediatric studies are urgently required to inform and standardise clinical practice, especially in the context of evolving drug resistance.

Impact of extracorporeal photopheresis on skin scores and quality of life in patients with steroid-refractory chronic GVHD.

There are few prospective studies evaluating the role of extracorporeal photopheresis (ECP) in chronic GVHD (cGVHD) and only occasional reports of the effect of ECP on patients' quality of life (QoL). We report a single-centre prospective study of patients undergoing fortnightly ECP for moderate or severe cGVHD. Response was assessed after 6 months of treatment using NIH scoring criteria and reduction in immunosuppression. QoL assessments were undertaken at baseline and at 6 months using the chronic GVHD symptom scale (cGVHD SS) and dermatology life quality index (DLQI). An intention-to-treat analysis showed that 19/38 (50%) of patients had a complete or partial response. Twenty-seven out of 38 patients completed 6 months of ECP treatment and 70% (19/27) had a complete or partial response. Eighty per cent of patients who completed 6 months of ECP treatment had a reduction in immunosuppression dose. A subset of patients completed QoL questionnaires. Seventeen out of 18 patients (94%) showed an improvement in scores. The mean cGVHD SS and mean DLQI score were both significantly lower after 6 months of ECP (22 compared with 36, P=0.012 and 3.4 compared with 6.9, P=0.009, respectively). This study confirms that ECP can lead to objective clinical responses and, in addition, may lead to an improvement in QoL in cGVHD.

What are the supportive and palliative care needs of patients with cutaneous T-cell lymphoma and their caregivers? A systematic review of the evidence.

BACKGROUND: Primary cutaneous T-cell lymphoma (CTCL) is progressive, can cause significant symptoms, and impacts on quality of life. Therefore supportive and palliative care might have a role in the care of patients and families. OBJECTIVES: To identify and appraise the available peer-reviewed evidence on the supportive and palliative care needs of patients and their caregivers. METHODS: A systematic review of the literature was conducted. Extracted data from eligible papers were collated in themes relating to supportive and palliative care needs and outcomes for patients, informal caregivers, health professionals and reported service models. RESULTS: Eighteen retained papers reported a symptom or quality-of-life measure. Five reported only these measures, 13 reported outcomes in relation to an intervention. Systemic therapy targeted at disease remission was the most commonly reported intervention (12/13). No quality-of-life tool was consistently used. Pruritus was frequently reported as an outcome (n = 9) often using the visual analogue scale, VAS itch. Psychosocial, spiritual and caregiver needs were reported infrequently or not at all. CONCLUSIONS: No measure is routinely used to measure supportive and palliative care outcomes in CTCL. Physical needs, particularly pruritus, were reported commonly; however, qualitative evidence of experience is limited. Caregivers' needs are rarely explored. To compare outcomes from clinical studies, a single multidimensional tool used in routine practice would be useful. Further work is needed to explore a model of service that meets the specific physical, psychosocial and spiritual needs of this group of patients and their carers.

A cutaneous lymphoma international prognostic index (CLIPi) for mycosis fungoides and Sezary syndrome.

BACKGROUND: There is no prognostic index for primary cutaneous T-cell lymphomas such as mycosis fungoides (MF) and Sezary syndrome (SS). METHOD: Two prognostic indices were developed for early (IA-IIA) and late stage (IIB-IVB) disease based on multivariate data from 1502 patients. End-points included overall survival (OS) and progression free survival (PFS). External validation included 1221 patients. FINDINGS: Significant adverse prognostic factors at diagnosis consisted of male gender, age >60, plaques, folliculotropic disease and stage N1/Nx for early stage, and male gender, age >60, stages B1/B2, N2/3 and visceral involvement for late stage disease. Using these variables we constructed two separate models each defined using 3 distinct groups for early and late stage patients: 0-1 (low risk), 2 (intermediate risk), and 3-5 factors (high risk). 10 year OS in the early stage model was 90.3% (low), 76.2% (intermediate) and 48.9% (high) and for the late stage model 53.2% (low), 19.8% (intermediate) and 15.0% (high). For the validation set significant differences in OS and PFS in early stage patients (both p<0.001) were also noted. In late stage patients, only OS differed between the groups (p=0.002). INTERPRETATION: This proposed cutaneous lymphoma prognostic index provides a model for prediction of OS in early and late stage MF/SS enabling rational therapeutic choices and patient stratification in clinical trials.

Skin lesions in adult liver transplant recipients: a study of 100 consecutive patients.

BACKGROUND: The surgical advances made in the area of organ transplantation along with the use of more efficacious immunosuppression have meant an increase in patient survival. This longer-living transplant population has started to exhibit cutaneous problems, some of which lead to an increased mortality while others lead to a decline in the quality of life. OBJECTIVES: The primary objective was to determine the different types of cutaneous lesions encountered in the adult liver transplant population. Secondary objectives were to determine the impact, if any, of the duration of transplant, the type of immunosuppression involved and the degree of sun exposure and skin phototype, on the skin cancers encountered in this transplanted population. METHODS: Two dermatologists examined 100 consecutive liver transplant recipients (LTRs) attending the transplant outpatient department. Skin examination included the face and whole body and lesions found were categorized into the following groups: cutaneous malignancies, squamoproliferative lesions, cutaneous infections and others that did not fall into any of these categories. RESULTS: The reasons for organ transplantation were numerous. The mean age at transplantation was 42.5 years. The average time since transplantation was 5.5 (range 0.75-16 years). Four patients developed skin cancers; among them there were a total of seven skin cancers (one squamous cell carcinoma, six basal cell carcinomas). Fungal infections accounted for 19% of all cutaneous infections seen, viral infections 2% and bacterial infections 5%. Triple-drug immunosuppressive therapy (ciclosporin A, azathioprine and prednisolone) was used in 35% of LTR patients, while dual therapy (tacrolimus and prednisolone) was used in 48% and monotherapy (tacrolimus) was used in 17% of LTRs. CONCLUSIONS: Immunosuppressive therapy is believed to be one of the most important risk factors in the development of skin cancer in solid organ transplant recipients. The relatively low prevalence of skin cancer in our liver transplant population may in part be explained by the relatively high percentage of recipients on dual and monotherapy (48% and 17% respectively), and the shorter duration of therapy. Our study suggests that although LTRs are at higher risk of developing nonmelanoma skin cancer than the general population, the risk is comparable with other solid organ transplant recipients.
