Significant impact of cutaneous T-cell lymphoma on patients' quality of life

Assessing Health-Related Quality of Life in Mycosis Fungoides and Sézary Syndrome: Unmet Needs

Mycosis fungoides (MF) and Sézary syndrome (SS) can impair multiple dimensions of health-related quality of life (HRQoL). Currently, there is no standardized assessment tool for measuring HRQoL in patients with MF/SS. Here, we describe the existing literature on multiple dimensions of HRQoL in MF/SS with a special focus on the gaps in the current knowledge and identify future directions necessary to assess the HRQoL of patients with this disease.

Characterization of cells and mediators associated with pruritus in primary cutaneous T-cell lymphomas

Patients with primary cutaneous T-cell lymphoma (CTCL) often experience severe and difficult-to-treat pruritus that negatively affects their quality of life (QoL). However, the mechanisms of pruritus in CTCL, including mycosis fungoides (MF), remain largely unknown, and detailed characteristics of CTCL-associated pruritus is not fully elucidated. To characterize pruritus in CTCL, cutaneous B-cell lymphoma (CBCL), and large plaque parapsoriasis (LPP), and to identify potential itch mediators involved in the pathogenesis of pruritus in CTCL patients. Clinical data and blood samples were collected from 129 healthy subjects and 142 patients. Itch intensity, QoL impairment, psychological distress, and sleep quality were assessed using validated questionnaires and instruments. Blood levels of BDNF, CCL24, GRP, IL-31, IL-33, sST2, substance P, TSLP, tryptase and total IgE were measured using ELISA or ImmunoCAP. Pruritus was prevalent in CTCL, LPP and CBCL patients, with higher prevalence and severity observed in CTCL. In CTCL, pruritus correlated with significant impairment in QoL, sleep, psychological distress. Compared to healthy controls, elevated levels of IL-31, IL-33, substance P, total IgE, tryptase, and TSLP were found in MF patients. A comparison of MF patients with and without pruritus revealed higher levels of IL-31, substance P, GRP, and CCL24 in the former. Itch intensity positively correlated with IL-31, GRP, CCL24, and tryptase levels. Pruritus significantly burdens CTCL patients, necessitating appropriate therapeutic management. Our findings suggest that various non-histaminergic mediators such as tryptase and IL-31 could be explored as novel therapeutic targets for managing pruritus in MF patients.

Unmet needs in treating itch: reaching beyond eczema

PURPOSE

Pruritus is an unpleasant sensation that creates the urge to scratch. In many chronic conditions, relentless pruritus and scratching perpetuates a vicious itch-scratch cycle. Uncontrolled itch can detrimentally affect quality of life and may lead to sleep disturbance, impaired concentration, financial burden, and psychological suffering. Recent strides have been made to develop guidelines and investigate new therapies to treat some of the most common severely pruritic conditions, however, a large group of diseases remains underrecognized and undertreated. The purpose of this article is to provide a comprehensive review of the challenges hindering the treatment of pruritus.

METHODS

An online search was performed using PubMed, Web of Science, Google Scholar, and ClinicalTrials.gov from 1994 to 2024. Included studies were summarized and assessed for quality and relevance in treating pruritus.

RESULTS

Several barriers to treating pruritus emerged, including variable presentation, objective measurement of itch, and identifying therapeutic targets. Itch associated with autoimmune conditions, connective tissue diseases, genodermatoses, cutaneous T-cell lymphoma, and pruritus of unknown origin were among the etiologies with the greatest unmet needs.

CONCLUSION

Treating pruritus poses many challenges and there are many itchy conditions that have no yet been addressed. There is an urgent need for large-scale controlled studies to investigate potential targets for these conditions and novel therapies.

Health-related quality of life and its influencing factors in patients with primary cutaneous B-cell lymphomas: A multicentric study in 100 patients

BACKGROUND

Primary cutaneous B-cell lymphomas (CBCL) are a group of rare malignant skin diseases that represent approximately 20%-30% of all primary cutaneous lymphomas (PCL). Previous studies revealed impaired health-related quality of life (HRQoL) in patients diagnosed with primary cutaneous T-cell lymphoma (CTCL). Currently, only small-sized studies investigated HRQoL in CBCL patients and lacked detailed analysis of respective subtypes.

OBJECTIVES

This study aims to investigate HRQoL in CBCL patients to identify independent factors of HRQoL impairment in CBCL patients.

METHODS

One hundred CBCL patients were recruited from eight German PCL centres in this multicentric, cross-sectional study from 2021 to 2022. The patients completed the dermatologic HRQoL questionnaire Skindex-29 and an investigator-designed 'CBCL-Questionnaire' with additional questions on HRQoL and clinical characteristics.

RESULTS

The Skindex-29 revealed that HRQoL in CBCL patients is impaired on a mild to moderate level. The multiple regression analysis identified parameters like worries about dying, feeling prejudiced/discriminated and impairment of daily activities to be independently associated with impairment of HRQoL. Highest scores for HRQoL impairment were found in patients with primary cutaneous follicle centre lymphoma while on rituximab treatment and in patients with primary cutaneous marginal zone lymphoma while on watchful waiting.

CONCLUSIONS

HRQoL is impaired in CBCL patients, even though, in the face of indolent disease course and favourable prognosis in the majority of cases. Of note, our investigator-designed tool identified worries about dying, feeling prejudiced/discriminated, and the type of treatment to have a negative impact on patients' HRQoL. Our study highlights the importance of a thorough patient-doctor communication to capture overall disease burden because generic HRQoL tools might lack of disease-specific items.

GZ17-6.02 interacts with bexarotene to kill mycosis fungoides cells

GZ17-6.02, composed of curcumin, harmine and isovanillin, has undergone phase I evaluation in patients with solid tumors (NCT03775525) with an RP2D of 375 mg PO BID. The biology of GZ17-6.02 in malignant T cells and in particular those derived from mycosis fungoides (MF) patients, has not been studied. GZ17-6.02 alone and in combination with standard-of-care agents was effective in killing MF cells. All three components are necessary for optimal killing of MF cells. GZ17-6.02 activated ATM, the AMPK, NFκB and PERK and inactivated ERK1/2, AKT, ULK1, mTORC1, eIF2α, and reduced the expression of BCL-XL and MCL1. GZ17-6.02 increased ATG13 S318 phosphorylation and the expression of Beclin1, ATG5, BAK and BIM. GZ17-6.02 in a dose-dependent fashion enhanced autophagosome formation and autophagic flux, and tumor cell killing. Signaling by ATM and AMPK were both required for efficient killing but not for the dose-response effect whereas ER stress (eIF2α) and macroautophagy (Beclin1, ATG5) were required for both efficient killing and the dose-response. Knock down of the death receptor CD95 reduced killing by ~20% and interacted with autophagy inhibition to further reduce killing, collectively, by ~70%. Inhibition of autophagy and knock down of death-mediators downstream of the mitochondrion, AIF and caspase 3, almost abolished tumor cell killing. Hence in MF cells, GZ17-6.02 is a multi-factorial killer, utilizing ER stress, macroautophagy, death receptor signaling and directly causing mitochondrial dysfunction.

Transcriptomic and proteomic analysis of tumor suppressive effects of GZ17-6.02 against mycosis fungoides

Mycosis fungoides (MF) is the most common form of cutaneous T-cell lymphoma (CTCL). Despite having a wide variety of therapeutic agents available for the treatment of MF, patients often suffer from a significant decrease in quality of life and rarely achieve long-term remission or complete cure, highlighting a need to develop novel therapeutic agents for this disease. The present study was undertaken to evaluate the efficacy of a novel anti-tumor agent, GZ17-6.02, which is composed of curcumin, harmine, and isovanillin, against MF in vitro and in murine models. Treatment of HH and MyLa cells with GZ17-6.02 inhibited the growth of both cell lines with IC50 ± standard errors for growth inhibition of 14.37 ± 1.19 µg/mL and 14.56 ± 1.35 µg/mL, respectively, and increased the percentage of cells in late apoptosis (p = .0304 for HH; p = .0301 for MyLa). Transcriptomic and proteomic analyses revealed that GZ17-6.02 suppressed several pathways, including tumor necrosis factor (TNF)-ɑ signaling via nuclear factor (NF)-kB, mammalian target of rapamycin complex (mTORC)1, and Pi3K/Akt/mTOR signaling. In a subcutaneous tumor model, GZ17-6.02 decreased tumor volume (p = .002) and weight (p = .009) compared to control conditions. Proteomic analysis of tumor samples showed that GZ17-6.02 suppressed the expression of several proteins that may promote CTCL growth, including mitogen-activated protein kinase (MAPK)1, MAPK3, Growth factor receptor bound protein (GRB)2, and Mediator of RAP80 interactions and targeting subunit of 40 kDa (MERIT)40.

Chlormethine gel in combination with other therapies for treatment of mycosis fungoides: a review with patient cases

Topical chlormethine gel has been approved as monotherapy for treatment of adult patients with mycosis fungoides (MF), the most common form of cutaneous T-cell lymphoma. In clinical practice, chlormethine gel is often combined with other skin-directed or systemic therapies to optimize response and target recalcitrant lesions. Positive outcomes with combination regimens using chlormethine gel and topical corticosteroids, phototherapy, retinoids, methotrexate, or interferon-α have been reported in literature. However, there are no treatment guidelines on the use of combination regimens with chlormethine gel. To provide real-world evidence and guidance on the use of chlormethine gel combination regimens, several cases of patients treated with chlormethine gel combined with phototherapy (n = 5), retinoids (n = 16), or mogamulizumab (n = 3) are presented. These different combination regimens showed promising results. Most patients had a complete or partial response following treatment and the combinations were well-tolerated over extended treatment periods. Patients receiving chlormethine gel with retinoids had long-term periods of remission, even after treatment discontinuation. Durations of response of up to 3 years were observed in these patients. This long-term disease control may be the result of disease-modifying effects of chlormethine. Previous studies have shown targeted reductions in malignant T-cell clones in patients treated with chlormethine gel as well as improved post-treatment responses. Further research is needed to determine the effectiveness and safety of combination treatment regimens with chlormethine gel and to assess the impact chlormethine gel has on disease control.

Psychological Distress and Treatment Outcome in Patients With Early-Stage Mycosis Fungoides

BACKGROUND

Skin diseases have been shown to worsen psychological distress, which, in turn, may be detrimental to treatment outcomes. Both the impact of psychological distress on response to treatment in mycosis fungoides (MF) and the effect of treatments on psychological well-being are unclear.

OBJECTIVES

To evaluate (1) the association between pretreatment psychological morbidity and treatment outcome in early-stage MF and (2) the impact of response to treatment on psychological well-being.

METHODS

This was a prospective cohort study of patients with early-stage MF who started a new stage-directed treatment for their disease. The response was determined using the modified severity-weighted assessment tool, and psychological distress was assessed using the 12-item General Health Questionnaire (GHQ-12) and Penn State Worry Questionnaire (PSWQ). Participants were followed for 1 year.

RESULTS

In all, 24 consecutive patients were recruited. Objective response rate was 71% (17/24), consistent with existing literature. Prior to treatment, 9 patients (38%) had clinically significant psychological distress on the GHQ-12, while 8 (33%) demonstrated high-level worry on the PSWQ. Of these patients, 6 had pathologic scores on both instruments. Patients with significantly less baseline anxiety/depression on the GHQ-12 responded better to treatment than patients with higher levels (P = .004). In addition, responders' mean GHQ-12 scores decreased by 39% and their PSWQ scores by 17%, whereas nonresponders' GHQ-12 scores increased by 93% (P = .042) and their PSWQ scores by 11% (P = .019).

CONCLUSIONS

These findings suggest that (1) baseline psychological distress is associated with worse outcomes in patients with early-stage MF and that (2) effective treatment improves psychological morbidity.

An update on mechanisms of pruritus and their potential treatment in primary cutaneous T-cell lymphoma

Primary cutaneous T-cell lymphomas (CTCL), which include mycosis fungoides (MF) and Sézary syndrome (SS), are a group of lymphoproliferative disorders characterized by clonal accumulation of neoplastic T-lymphocytes in the skin. Severe pruritus, one of the most common and distressing symptoms in primary CTCL, can significantly impair emotional well-being, physical functioning, and interpersonal relationships, thus greatly reducing quality of life. Unfortunately, effectively managing pruritus remains challenging in CTCL patients as the underlying mechanisms are, as of yet, not fully understood. Previous studies investigating the mechanisms of itch in CTCL have identified several mediators and their corresponding antagonists used for treatment. However, a comprehensive overview of the mediators and receptors contributing to pruritus in primary CTCL is lacking in the current literature. Here, we summarize and review the mediators and receptors that may contribute to pruritus in primary CTCL to explore the mechanisms of CTCL pruritus and identify effective therapeutic targets using the PubMed and Web of Science databases. Studies were included if they described itch mediators and receptors in MF and SS. Overall, the available data suggest that proteases (mainly tryptase), and neuropeptides (particularly Substance P) may be of greatest interest. At the receptor level, cytokine receptors, MRGPRs, and TRP channels are most likely important. Future drug development efforts should concentrate on targeting these mediators and receptors for the treatment of CTCL pruritus.

Unveiling the hidden struggles: Exploring the profound impact of advanced stage cutaneous T-cell lymphoma on quality of life

Erythrodermic mycosis fungoides and Sézary syndrome are chronic, relapsing-remitting diseases that greatly impacts patients' quality of life (QoL). Mogamulizumab-kpkc (Mogamulizumab) is a novel therapeutic agent for cutaneous T-cell lymphomas with a notable impact on progression-free survival. Qualitative assessment methods allow a broader exploration and greater insight in individual patient experience than quantitative studies. However, there is limited data on the impact of mogamulizumab on health-related QoL. To investigate the impact of erythrodermic cutaneous T-cell lymphoma (E-CTCL) on QoL and the effect of mogamulizumab on the QoL. Semi-structured interview were conducted with seven patients with E-CTCL that were receiving mogamulizumab treatment. Five major themes arose: Diagnosis and the diagnostic delay and uncertainty experienced by participants; Physical functioning due to the high symptom burden; Psychological and social functioning considering the significant impact on daily life; Treatment and the effect of mogamulizumab; and Support by family, friends and health professionals. Mogamulizumab therapy resulted in a significant decrease of symptoms. The small sample size should also be taken into account although data saturation was reached. This study gives a broad insight into the large impact of E-CTCL and the major consequences on the physical functioning as well as on the emotional/psychological and social well-being. Mogamulizumab appears to have a positive effect on symptoms.

Accessibility and readability of online patient education on cutaneous lymphomas

Background

Patients facing a cutaneous lymphoma diagnosis frequently turn to the internet for information but finding patient-accessible education may be a challenge.

Objective

To investigate accessibility and readability of patient-oriented online education on cutaneous lymphomas, including cutaneous T-cell and B-cell lymphoma subtypes.

Methods

This study queried a search engine for 11 cutaneous lymphoma terms, resulting in 1083 webpages. Webpages were screened using defined inclusion/exclusion criteria; literature directed to physicians and scientists was excluded. Webpages were stratified by academic/nonacademic and dermatology/nondermatology hosts and assessed by order of appearance. Readability, including text complexity, was analyzed for grade level understanding using 5 established calculators. Overall readability was assessed by Flesch-Kincaid Reading Ease.

Results

Academic webpages had earlier order of appearance. There was a dearth in dermatology-hosted webpages. Rarer cutaneous lymphomas yielded fewer patient-accessible results. Search term readability significantly exceeded the American Medical Association-recommended sixth grade level (P < .001∗), with higher grade levels for cutaneous T-cell lymphoma subtype webpages than cutaneous B-cell lymphoma subtypes.

Limitations

Webpage quality, accuracy, and language were not assessed.

Conclusion

Current online education for cutaneous lymphomas exceeds the American Medical Association's maximum readability recommendation. There is a need for more patient-accessible education amidst predominance of scientific literature, greater dermatology host websites, and enhanced readability of existing online education.

Overall survival in the UK in mycosis fungoides or Sézary syndrome cutaneous T-cell lymphoma: comparative effectiveness of mogamulizumab versus current standard of care

Aim: Due to extensive treatment switching in the MAVORIC trial, lack of UK regulatory licence for the comparator, overall survival (OS) with mogamulizumab was compared with patients with previously treated advanced mycosis fungoides/Sézary syndrome (MF/SS) in real-world setting. Design, setting & participants: Data were from the Hospital Episode Statistics database (all patients in NHS secondary care system in 2009-2019). Patients were selected according to trial inclusion criteria, then trial and HES samples were matched on selected variables with significant imbalance. Outcomes: The analysis indicated significant improvement in OS for mogamulizumab treatment compared with UK clinical practice (hazard ratio: 0.36, 95% CI: 0.24, 0.53). Conclusion: Results suggest an OS advantage for patients with advanced MF/SS treated with mogamulizumab in MAVORIC trial compared with UK clinical practice.

Mechanism of action of chlormethine gel in mycosis fungoides

Mycosis fungoides (MF), the most common type of cutaneous T-cell lymphoma, is characterized by proliferation of malignant skin-tropic T cells. Progression from early-stage disease (skin patches and/or plaques) to more advanced stages (cutaneous tumours, erythroderma or extracutaneous involvement) occurs slowly and can be discontinuous. Prognosis is poor for the ~25% of patients who progress to advanced disease. Patients at any stage of MF may experience reduced health-related quality of life (QoL) via a spectrum of physically and psychologically debilitating symptoms that can impact many aspects of daily life. Allogeneic stem-cell transplantation is a curative treatment option for some patients with advanced disease, but otherwise there is currently no cure for MF; patients are often refractory to several treatments and require lifelong management. The goals of therapy are symptom control, prevention of disease progression, avoidance of treatment-related toxicity and maintenance/improvement of QoL. Although treatment regimens exist it can be difficult to know how to prioritize them, hence therapies are tailored according to patient needs and drug availabilities, following clinical recommendations. International consensus guidelines recommend skin-directed therapies (SDTs) as first-line treatment for early-stage disease, and SDTs combined with systemic therapy for advanced stages. Chlormethine (CL), also known as mechlorethamine, chlorethazine, mustine, HN2, caryolysine and embichin, is a synthetic deoxyribonucleic acid-alkylating agent that was used as a chemical weapon (mustard gas) during the First World War. Subsequent investigation revealed that survivors of mustard gas exposure had lymphocytopenia, and that CL could inhibit rapidly proliferating malignant T cells. CL has since been developed as a topical treatment for MF and prescribed as such for over 70 years. This review aims to summarize the current knowledge regarding the mechanism of action of CL in the cutaneous micro-environment, in the specific context of MF treatment.

Cost-utility analysis of mogamulizumab in advanced mycosis fungoides and Sézary syndrome cutaneous T-cell lymphoma

Aim: This study assessed the cost-utility of mogamulizumab, a novel monoclonal antibody, versus established clinical management (ECM) in UK patients in previously treated advanced mycosis fungoides (MF)/Sézary syndrome (SS). Materials & methods: Lifetime partitioned survival model based on overall survival, next treatment-free survival and the use of allogeneic stem cell transplant was developed. Inputs were from the pivotal MAVORIC trial, real-world evidence and published literature. Extensive sensitivity analyses were conducted. Results: Discounted incremental quality-adjusted life years (QALYs), costs and incremental cost-effectiveness ratio were 3.08, £86,998 and £28,233. Results were most sensitive to the survival extrapolations, utilities and costs after loss of disease control. Conclusion: Mogamulizumab is a cost-effective alternative to ECM in UK patients with previously treated advanced MF/SS.

Gender disparities in health-related quality of life (HRQoL) in patients with cutaneous T-cell lymphoma

Patients with cutaneous T-cell lymphoma (CTCL) often experience debilitating symptoms that impair health-related quality of life (HRQoL). Existing evidence for HRQoL differences with respect to gender is conflicting.

Objective

To investigate potential gender differences in HRQoL for patients with CTCL.

Methods

We performed a cross-sectional study to assess HRQoL in patients with CTCL by partnering with the Cutaneous Lymphoma Foundation to distribute an electronic survey from February to April 2019.

Results

A total of 292 patient responses (66% women, mean age 57 years) were included in the analysis. Most of the cohort had early-stage (IA-IIA) (74%; 162/203) mycosis fungoides (MFs) (87%; 241/279), followed by Sézary syndrome (SS) (12%; 33/279). Women with CTCL experienced significantly worse HRQoL compared with men (Skindex-16: 51±26 vs. 36±26, P ≤ 0.001; FACT-G: 69±21 vs. 77±16, P = 0.005). This gender difference was present even when controlling for stage of disease. Women experienced worse HRQoL in all three of the Skindex-16 subscales (symptoms: β = 14.0, P ≤ 0.001; emotions: β = 15.1, P ≤ 0.001; functioning: β = 11.3, P = 0.006), but only two of the four FACT-G subscales (physical: β =-2.8, P ≤ 0.001; emotional: β = -2.0, P = 0.004).

Limitations

Due to the method of distribution of the survey, we were unable to estimate a participant response rate. Participants' diagnosis and stage were self-reported.

Conclusion

In this cohort women with CTCL experienced significantly worse HRQoL when compared to men. Additional studies are necessary to determine what factors contribute to this gender disparity.

Mycosis fungoides and Sézary syndrome

Mycosis fungoides (MF) and Sézary syndrome (SS) are a distinct disease entity of cutaneous T-cell lymphoma with heterogenous clinical features and prognosis. MF mainly involves skin and usually shows an indolent and favorable clinical course. In patients with advanced-stage disease, extracutaneous involvement including lymph nodes, viscera, and blood, or large cell transformation may be observed. SS is a leukemic form of advanced-stage MF, characterized by generalized erythroderma. Early-stage MF can be treated with skin-directed therapy. However, patients with refractory or advanced-stage disease are associated with severe symptoms or poor prognosis, requiring systemic therapy. Recent progress in understanding the pathogenesis of MF/SS has contributed to advances in the management of these rare diseases. This review aims to describe the clinical manifestations, diagnosis, risk stratification, and treatment strategy of MF/SS, focusing on the recent updates in the management of these diseases.

Differential Response of Mycosis Fungoides Cells to Vorinostat

Mycosis fungoides (MF) is the most common form of cutaneous T-cell lymphoma (CTCL) and is characterized by epidermotrophism of malignant CD4+ T-lymphocytes. When MF advances to a recurrent stage, patients require treatment with systemic therapies such as vorinostat, a histone deacetylase inhibitor. While vorinostat has been shown to exhibit anti-tumor activity in MF, its exact molecular mechanism has yet to be fully discerned. In the present study, we examined the transcriptomic and proteomic profiles of vorinostat treatment in two MF cell lines, Myla 2059 and HH. We find that vorinostat downregulates CTLA-4, CXCR4, and CCR7 in both cell lines, but its effect on several key pathways differs between the two MF cell lines. For example, vorinostat upregulates CCL5, CCR5, and CXCL10 expression in Myla cells but downregulates CCL5 and CXCL10 expression in HH cells. Furthermore, vorinostat upregulates IFN-γ and IL-23 signaling and downregulates IL-6, IL-7, and IL-15 signaling in Myla cells but does not affect these pathways in HH cells. Although Myla and HH represent established MF cell lines, their distinct tumor origin from separate patients demonstrates that inherent phenotypic variations within the disease persist, underscoring the importance of using a variety of MF cells in the preclinical development of MF therapeutics.

Oral Mycosis Fungoides: Report of 2 Cases and Review of the Literature

Oral and laryngeal cutaneous T-cell lymphoma (CTCL) is rare and usually associated with poor prognosis. Here, we discuss 2 cases of oral CTCL that developed in heavily pretreated patients and provide a review of the literature. The first case is of a 46-year-old African American male with rapidly progressive disease, presenting with a lesion on his hard palate 6 months after being diagnosed with a CD4+CD8+ CTCL. His cutaneous disease was widespread with tumors on >80% of his body surface area. Unfortunately, the patient died 2 ½ years after his CTCL diagnosis and 7 months after developing the oral CTCL lesion. The second case is of a 38-year-old African American male with stage IIb CD3+CD4+CD30+ mycosis fungoides (MF), who developed a tumor on the hard palate 6 months after diagnosis. He received palliative radiation to the oral lesion and multiple lines of systemic therapy for pulmonary, laryngeal, esophageal, and gastric involvement. Biopsy of the gastric lesions showed a CD30+ T-cell lymphoma with the same clonal peak as in his skin but with large cell transformation. Brentuximab vendoin was started, and the patient is now in complete remission, 30 months later. From the 76 cases of oral CTCL that have been reported in the English language, six were of transformed MF. The most common sites affected were the tongue and palate, and the most common presentation were erythematous or ulcerated tumors, plaques, or nodules associated with dysphagia and pain. Oral CTCL typically occurs years after the initial diagnosis of CTCL and portend a poor prognosis with an average survival of just over 1 year after development of oral lesions.

Real-Life Barriers to Diagnosis of Early Mycosis Fungoides: An International Expert Panel Discussion

Mycosis fungoides (MF) is a rare, primary cutaneous T-cell lymphoma that is challenging to diagnose due to its heterogeneous clinical presentation and complex histology. The subtlety of the initial clinical appearance of MF can result in diagnostic delays and hesitancy to refer suspected cases to specialist clinics. An unmet need remains for greater awareness and education. Therefore, an international expert panel of dermatologists, oncologists, hematologists, and dermatopathologists convened to discuss and identify barriers to early and accurate MF diagnosis that could guide clinicians toward making a correct diagnosis. Confirmation of MF requires accurate assessment of symptoms and clinical signs, and subsequent correlation with dermatopathological findings. This review summarizes the expert panel's guidance, based on the literature and real-life experience, for dermatologists to help include MF in their list of differential diagnoses, along with simple clinical and histopathologic checklists that may help clinicians to suspect and identify potential MF lesions and reduce diagnostic delays.

Italian Real-Life Experience on the Use of Mogamulizumab in Patients with Cutaneous T-Cell Lymphomas

Mycosis fungoides and Sèzary syndrome are the most studied subtypes common cutaneous T-cell lymphomas. The current treatment objective is to improve the clinical manifestations of the disease in the affected areas, to relieve symptoms and to halt disease progression. Patients with early-stage mycosis fungoides are usually managed with skin-directed therapies, whereas patients with resistant or advanced-stage mycosis fungoides or Sèzary syndrome often require systemic drugs. Over the last decade, new drugs have been developed, increasing the breadth of treatment options for cutaneous T-cell lymphomas patients. Mogamulizumab is a first-in-class defucosylated humanized IgG1 κ monoclonal antibody, which exerts its anti-tumour action by selectively binding to C-C chemokine receptor 4 and increasing antibody-dependent cellular cytotoxicity activity against malignant T-cells. Several clinical trials showed that mogamulizumab is able to effectively control the cutaneous T-cell lymphomas in each site (skin, blood, lymph nodes and viscera), improving patients' symptoms, function and overall quality of life with a manageable safety profile. In this report, we discuss 12 cases of patients with mycosis fungoides or Sèzary syndrome successfully treated with mogamulizumab in real-life clinical practice in Italy.

"Knock Me Out": The Challenges of Managing Pain Due to Cutaneous T Cell Lymphomas: A Case Report

Cutaneous T cell lymphomas are associated with distressing symptoms, including pain and pruritus that negatively impact quality of life. Early involvement of palliative care can provide relief of symptoms and address multifaceted distress. This case highlights the complex management of cutaneous T cell lymphoma pain and associated symptoms, including existential and psychosocial distress. Our patient required frequent titration and rotation of high-dose opioids and adjuvant analgesics, ultimately requiring transfer to the intensive care unit for analgosedation. Total skin loss and disease complications led to his death after a compassionate withdrawal of life support. Cutaneous T cell lymphoma pain can be successfully managed with an interdisciplinary approach, early palliative care, and aggressive pain management. Complications from advanced disease, superinfection, and multidimensional distress complicate the efficacy of a multimodal analgesic approach. Further research is needed to deepen our understanding of how to optimally alleviate suffering within this vulnerable population.

[Quality of life of patients with mycosis fungoides and Sézary syndrome]

Mycosis fungoides as the most common type and Sézary syndrome as a leukemic variant belong to the rare group of cutaneous T‑cell lymphomas. Both diseases are considered incurable and show a chronic course. Since there is no curative treatment, maintaining quality of life and relief of symptoms should be important elements when treating patients with mycosis fungoides and Sézary syndrome. Pruritus, which is a common and burdensome symptom of cutaneous T‑cell lymphoma, may negatively impact quality of life. Pruritus and quality of life can be assessed with established measurement tools. Consistent recording enables physicians to recognize restrictions in physical and psychosocial aspects of quality of life early so that therapy can be adapted.

Primary cutaneous lymphoma: recommendations for clinical trial design and staging update from the ISCL, USCLC, and EORTC

The number of patients with primary cutaneous lymphoma (PCL) relative to other non-Hodgkin lymphomas (NHLs) is small and the number of subtypes large. Although clinical trial guidelines have been published for mycosis fungoides/Sézary syndrome, the most common type of PCL, none exist for the other PCLs. In addition, staging of the PCLs has been evolving based on new data on potential prognostic factors, diagnosis, and assessment methods of both skin and extracutaneous disease and a desire to align the latter with the Lugano guidelines for all NHLs. The International Society for Cutaneous Lymphomas (ISCL), the United States Cutaneous LymphomaConsortium (USCLC), and the Cutaneous Lymphoma Task Force of the European Organization for the Research and Treatment of Cancer (EORTC) now propose updated staging and guidelines for the study design, assessment, endpoints, and response criteria in clinical trials for all the PCLs in alignment with that of the Lugano guidelines. These recommendations provide standardized methodology that should facilitate planning and regulatory approval of new treatments for these lymphomas worldwide, encourage cooperative investigator-initiated trials, and help to assess the comparative efficacy of therapeutic agents tested across sites and studies.

Low-Dose Volumetric Modulated Arc Therapy for a Patient With Head and Neck Involvement of Mycosis Fungoides: A Case Report With a Review of Literature

Mycosis fungoides (MF) is the most common type of cutaneous T-cell lymphoma that slowly progresses over a period of years to decades. In some cases, lesions that spread to the scalp, neck, or facial skin can have a significant impact on cosmetic appearance and a patient's quality of life. Among the various treatments, radiation therapy is one of the most effective treatment modalities for patients with symptomatic cutaneous lesions. We report on an MF patient who had gradually increasing patches and plaques on the scalp, face, and neck and who underwent irradiation with 20 Gy administered in 10 fractions using volumetric modulated arc therapy. After undergoing this highly conformal technique, the patient obtained prolonged local control and significant alleviation of symptoms with acceptable adverse events. This technique constitutes a promising approach for treating a complex target due to its ability to provide homogeneous coverage of irregularly shaped target volumes along with its ability to preserve organs at risk. In addition, we systematically reviewed clinical reports on the management of extensive cutaneous lesions in MF patients undergoing other irradiation techniques.

Quality of Life and Survivorship in Lymphoma

PURPOSE OF REVIEW

With an increasing number of long-term lymphoma survivors, there has been emphasis on optimizing quality of life and identifying survivorship challenges. This review summarizes the latest advancements pertaining to health-related quality of life and survivorship in lymphoma.

RECENT FINDINGS

Quality of life can vary from diagnosis through survivorship though some physical, social, and emotional effects may be persistent. Incorporation of patient reported outcomes enables recognition of factors that significantly impact quality of life. A greater understanding of quality of life and survivorship issues has generated momentum for practice change, improving education, and designing behavior related interventions. Patients with lymphoma face many challenges as they navigate their cancer experience. There is a tremendous opportunity to build upon this work through well-designed prospective longitudinal studies aimed at identifying vulnerable patient groups and impactful points of intervention during survivorship.

Cannabis use among patients with cutaneous lymphoma: A cross-sectional survey

OBJECTIVE

To evaluate patterns of cannabis use in patients with cutaneous lymphoma (CL), as well as the association between cannabis use and itch specifically.

DESIGN

Cross-sectional survey created in partnership with the Cutaneous Lymphoma Foundation (CLF).

SETTING

The online survey was distributed electronically via email to the CLF listserv and links posted to social media over a 2-week period. Main Outcome Measures Respondents were classified as current cannabis users, prior users, and never users. A visual analog scale (VAS) was used to assess itching severity, improvement of itch, and interest in learning about cannabis.

RESULTS

A total of 119 patient responses (61% female, mean age 59y) were included in analysis. The majority had mycosis fungoides or Sézary syndrome (74%; 88/119) and early stage (IA-IIA) disease (56%; 48/86). Mean VAS itch score was 3.2 + 2.8 for the cohort. Over half (55%; 60/110) reported ever having used cannabis, with 22% (24/110) endorsing current cannabis use. Common methods of cannabis use were smoking (54%) and vaporizing (46%). 25% (6/24) of current users reported using cannabis specifically to treat itch; these respondents noted that cannabis resulted in moderate improvement of itching (mean 6.6/10). There was strong interest in learning more about cannabis and cancer, and most desired this information from their CL doctor/nurse.

CONCLUSIONS

Cannabis use is common among patients with CL, and patients report improvement of itching as a result of using cannabis. Further studies are needed to elucidate the risks and benefits of cannabis use in this patient population.

Impact of Mogamulizumab in Real-Life Advanced Cutaneous T-Cell Lymphomas: A Multicentric Retrospective Cohort Study

Simple Summary

Mogamulizumab is a recent monoclonal antibody prescribed in the second line to treat advanced mycosis fungoides and Sézary syndromes. We collected data from all patients who used mogamulizumab in six French university hospitals until 1 September 2021. Our primary objective was to determine the median progression free survival (PFS). Secondary objectives were to consider tolerance regarding side effect occurrence and severity. Twenty-one patients were included, with a median time of follow-up of 11.6 months, and progression-free survival was estimated at 22 months. Twenty patients presented adverse events, of which 10 were severe. The median time between the introduction of mogamulizumab and the first adverse event was 21 days. Our study suggests that mogamulizumab is a significant treatment option to extend PFS in patients with advanced refractory cutaneous T-cell lymphomas (CTCL). The long-term safety of mogamulizumab was determined to be acceptable since we reported few grade III–IV adverse events (AEs) compared to other systemic treatments.

Abstract

Background: Advanced mycosis fungoides (MF) and Sézary syndrome (SS) are rare, aggressive cutaneous T-cell lymphomas that may be difficult to treat. Mogamulizumab is a recent monoclonal antibody targeting the CCR4 receptor expressed on the surface of Sézary cells. It can be prescribed in MF/SS stages III to IV in the second line after systemic therapy or in stages IB-II after two unsuccessful systemic therapies. We lack data on long-term efficiency and potential side effects in real-life conditions. Our study aims to determine efficacy considering the median PFS of advanced CTCL with mogamulizumab. Secondary objectives were to consider tolerance and estimate delay until side effects appeared. Methods: Data on patients with advanced cutaneous T-cell lymphomas were collected since French Authorization, in six French university hospitals. Patients were followed until they stopped mogamulizumab because of relapse or toxicity. For those still treated by mogamulizumab, the end point was 1 September 2021. We excluded 3 patients as they had already been included in the MAVORIC study and data was not available. Results: The median time of follow-up was 11.6 months. Of the 21 patients included, we reported four full-response patients, eight in partial response, one in stability, three in progression, and five were deceased. One patient had visceral progression, and seven had new lymphadenopathy. Progression-free survival was estimated at 22 months. Twenty patients presented adverse events, of which 10 were severe, i.e., grade III-IV. The median time between the introduction of mogamulizumab and the first adverse event was 21 days. Conclusions: Our study suggests that mogamulizumab can give patients with advanced refractory CTCL a consequent PFS, estimated at 22 months. The long-term safety of mogamulizumab was determined to be acceptable since we reported few grade III–IV AEs, comparable with other studies. No other study using real-life data has been performed to investigate the AEs of mogamulizumab.

Top Ten Tips Palliative Care Clinicians Should Know About Caring for Patients with Cutaneous T Cell Lymphoma

Cutaneous T cell lymphoma and its subtypes, mycosis fungoides (MF) and Sézary syndrome (SS), comprise a spectrum of chronic lymphoproliferative disorders in which neoplastic T cells accumulate within the skin and visceral organs. This process is frequently characterized by severe pain, nonpain symptoms, and physical disfigurement. Significant emotional, spiritual, and existential distress is also felt by many of these patients as they experience a chronic, often incurable disease. Patients suffering from these diseases, though not commonly encountered, can benefit greatly from palliative care support. In this article, a team of palliative care clinicians, critical care physicians, and an oncologist specializing in lymphoma offer 10 tips to help palliative care teams to support these vulnerable and often-distressed patients and their caregivers.

Dermatologic Events Associated with the Anti-CCR4 Antibody Mogamulizumab: Characterization and Management

The CCR4-directed monoclonal antibody mogamulizumab has been shown to significantly improve progression-free survival and overall response rate compared with vorinostat in adults with relapsed/refractory mycosis fungoides (MF) and Sézary syndrome (SS). One of the most common adverse events seen with mogamulizumab in MF/SS patients is rash. Because of the protean nature of MF/SS and the variable clinical and histopathological features of mogamulizumab-associated rash, healthcare providers may have difficulty distinguishing rash from disease, and may not be aware of appropriate treatment strategies for this generally manageable adverse event. The objective of this report was to combine results from published literature with experiences and recommendations from multiple investigators and institutions into clinical best practice recommendations to assist healthcare providers in identifying and managing mogamulizumab-associated rash. Optimal management, which includes biopsy confirmation and steroid treatment, requires a multidisciplinary approach among oncology, dermatology, and pathology practitioners.

The impact of gender, age, race/ethnicity, and stage on quality of life in a spectrum of cutaneous lymphomas

PURPOSE

Cutaneous lymphomas (CLs) are a group of rare, potentially disfiguring and disabling cancers that can have a significant impact on quality of life (QoL). While previous studies have shown that mycosis fungoides (MF) and Sézary syndrome (SS) impair QoL, the effect of other types of CL on QoL has not been evaluated.

OBJECTIVE

To determine the impact of disease on QoL in all CL patients and to assess how QoL between the CL sub-types varies by demographic and clinical factors.

METHODS

The Cutaneous Lymphoma Distress Questionnaire (CL-DQ) was used to assess QoL. All CL patients seen in a multidisciplinary CL clinic were screened for eligibility. Questionnaire responses were collected over a 22-month period between 2017 and 2019. A cross-sectional analysis of CL-DQ scores from an initial visit was performed to determine the effect of disease on QoL across CL sub-types and the potential impact of patient demographics, CL sub-type, and type of treatment.

RESULTS

The study population consisted of 151 patients presenting with distinct types of cutaneous B- and T-cell lymphomas. Notable across the study population were the findings of frustration (44%), worry about progress/spread (43%), itching/pruritus (32%), and embarrassment/shame (28%). QoL was found to be most negatively affected in SS patients, females, younger patients, Black patients, and those with advanced stages of MF/SS.

CONCLUSIONS

Impairment of QoL due to CL correlates with gender, age, race/ethnicity, and stage of MF/SS. While the negative impact on QoL is most pronounced in SS patients, other CL sub-types also affect QoL and impact psychosocial distress. Our findings highlight the need for QoL assessment in all CL patients and further examination of disparities noted across demographic groups.

Mycosis fungoides and Sézary syndrome

Mycosis fungoides (MF) and Sézary syndrome (SS) are primary cutaneous T-cell lymphomas (CTCL) with not yet fully understood etiology and pathogenesis. Conceptually, MF and SS are classified as distinct entities arising from different T helper cell subsets. MF is the most common CTCL entity, while SS is very rare. MF presents clinically with patch, plaque and/or tumor stages, but can also evolve as erythroderma, which in turn is pathognomonic for SS. SS is characterized by a detectable tumor-cell burden (Sézary cells) in the peripheral blood consistent with advanced-stage disease and a poor prognosis. In early-stage disease of MF, which is the predominant form, the prognosis is generally favorable. However, in up to 30 % of patients, there is progression of skin lesions, which can ultimately lead to visceral involvement. The histological manifestation of MF can be subtle in early-stage disease and therefore a careful clinicopathological correlation is paramount. The treatment of MF/SS is dependent on the disease stage. Therapeutic options include both skin-directed and systemic regimens. Apart from allogeneic stem cell transplantation (alloSCT), there is as yet no curative therapy for MF/SS. Accordingly, the treatment approach is symptom oriented and aims to reduce the tumor burden and improve health-related quality of life. However, the therapeutic landscape for CTCL is constantly being expanded by the discovery of novel therapeutic targets.

Quality of life in patients with Mycosis Fungoides and Sézary Syndrome: a systematic review of the literature

Cutaneous T‐cell Lymphoma’s (CTCL) are a rare, heterogeneous group of T‐cell lymphomas that primarily manifest in the skin. Mycosis fungoides (MF) and Sézary syndrome (SS) are considered the classic types of CTCL. The diverse manifestation of CTCL results in a wide range of symptoms with a possible mild to severe impact on Quality of Life (QoL) depending on the disease stage. Previous studies on QoL in CTCL patients report diverse patient populations and use many different QoL instruments. In the current literature, a clear overview on the influence of the different stages of disease (early MF, late‐stage MF/SS or total group) on the QoL is lacking. Therefore, a systematic search of the literature was conducted using the PubMed, Embase, PsycINFO and Web of Science databases. Studies were included if they described QoL in patients with MF and SS retrieved by standardized instruments or qualitative interviews. In total, 24 studies were included using 18 different questionnaires to report on dermatology‐specific, cancer‐specific and generic QoL. The effect on QoL was found to be greater in patients with late‐stage disease as compared to early stage disease, with significant impairments on functional, emotional and physical domains. Nonetheless, even in patients with limited disease, QoL was mildly to moderately affected. Overall, pruritus was the most frequent reported and most bothersome symptom. Significant influence of the disease on daily life activities were found, not only in patients but also on caregivers and family. This broad, structured overview on QoL in MF and SS patients underlines the influence of disease stage on QoL, and therefore, recommends future studies to distinguish between disease stages when reporting results. Furthermore, this overview can inform clinicians in clinical practice by creating awareness of QoL deficits according to disease stage.

Lack of impact of type and extent of prior therapy on outcomes of mogamulizumab therapy in patients with cutaneous T cell lymphoma in the MAVORIC trial

Patients with mycosis fungoides (MF) and Sézary syndrome (SS) often require multiple lines of systemic therapy. In the phase 3 MAVORIC study (NCT01728805), mogamulizumab demonstrated superiority to vorinostat in median progression-free survival (PFS) and confirmed overall response rate (ORR) in patients with MF/SS. This post hoc analysis examined the effects of number and type of prior systemic therapies on mogamulizumab response. MAVORIC patients randomized to mogamulizumab (1.0 mg/kg intravenously weekly) or vorinostat (400 mg orally daily) were grouped by number of prior therapies and immunomodulatory activity of immediate prior systemic therapy while also considering time elapsed since treatment. ORR, PFS, and duration of response (DOR) did not vary with number of prior therapies. ORR and DOR remained consistent regardless of immediate prior therapy type. Additionally, immunomodulatory activity of the last prior therapy and time from prior treatment generally did not affect the ORR or PFS observed in response to mogamulizumab.

Integrative medicine use in patients with cutaneous T-Cell lymphoma: A cross-sectional survey study

OBJECTIVES

To characterize patterns of integrative medicine (IM) use and health-related quality of life (HRQoL) in patients with cutaneous T-cell lymphoma (CTCL).

DESIGN

Cross-sectional, online survey, created in conjunction with the Cutaneous Lymphoma Foundation (CLF).

SETTING

A link to the online survey was posted on the CLF Facebook page and emailed to the CLF listserv; 372 survey responses were received.

MAIN OUTCOME MEASURES

The study outcomes were IM use, cancer symptoms, and HRQoL measured via the Skindex-16 and Functional Assessment of Cancer Therapy-General (FACT-G).

RESULTS

A total of 292 patient responses (66 % female, median age 59y) were included in analysis. 87 % had mycosis fungoides and 12 % had Sézary syndrome. A majority (59 %) of patients reported using IM for their CTCL, with 48 % using IM to treat their disease and 47 % using IM to manage their symptoms. The most commonly used IM were vitamins/minerals (32 %), prayer/meditation (26 %), diet (24 %), and exercise/yoga (22 %). Higher itch scores were reported by patients using IM compared to non-users (31 (IQR 10-62) and 18 (IQR 3-46) respectively; p = 0.002). HRQoL was worse among patients who reported IM use; median Skindex-16 scores were 54 (IQR 28-72) among IM users compared to 33 (IQR 19-57) for non-IM users (p < 0.001).

CONCLUSIONS

IM use is common among patients with CTCL, particularly those with worse itching and worse HRQoL. IM interventions require further study given use by CTCL patients to treat disease and ameliorate symptoms.

IL-31 and IL-8 in Cutaneous T-Cell Lymphoma: Looking for Their Role in Itch

The itch associated with cutaneous T-cell lymphoma (CTCL), including Mycosis Fungoides (MF) and Sézary syndrome (SS), is often severe and poorly responsive to treatment with antihistamines. Recent studies have highlighted the possible role of interleukins in nonhistaminergic itch. We investigated the role of IL-31 and IL-8 in CTCL, concerning disease severity and associated itch. Serum samples of 27 patients with CTCL (17 MF and 10 SS) and 29 controls (blood donors) were analyzed for interleukin- (IL-) 31 and IL-8; correlations with disease and itch severity were evaluated. IL-31 serum levels were higher in CTCL patients than in controls and higher in SS than in MF. Also, serum IL-31 levels were higher in patients with advanced disease compared to those with early disease, and they correlated positively with lactate dehydrogenase and beta 2-microglobulin levels, as well as with the Sézary cell count. Itch affected 67% of CTCL patients (MF: 47%; SS: 100%). Serum IL-31 levels were higher in itching patients than in controls and in patients without itching. There was no association between serum IL-8 and disease severity, nor with itching. Serum IL-8 levels correlated positively with peripheral blood leukocyte and neutrophil counts in CTCL patients. Our study suggests a role for IL-31 in CTCL-associated itch, especially in advanced disease and SS, offering a rational target for new therapeutic approaches. Increased serum IL-8 observed in some patients may be related to concomitant infections, and its role in exacerbating itch by recruiting neutrophils and promoting the release of neutrophil proteases deserves further investigation.

Efficacy and safety of mogamulizumab by patient baseline blood tumour burden: a post hoc analysis of the MAVORIC trial

Background

Mogamulizumab was compared with vorinostat in the phase 3 MAVORIC trial (NCT01728805) in 372 patients with relapsed/refractory mycosis fungoides (MF) or Sézary syndrome (SS) who had failed ≥1 prior systemic therapy. Mogamulizumab significantly prolonged progression‐free survival (PFS), with a superior objective response rate (ORR) vs. vorinostat.

Objectives

This post hoc analysis was performed to evaluate the effect of baseline blood tumour burden on patient response to mogamulizumab.

Methods

PFS, ORR, time to next treatment (TTNT), skin response (modified Severity‐Weighted Assessment Tool [mSWAT]) and safety were assessed in patients stratified by blood classification (B0 [n = 126], B1 [n = 62], or B2 [n = 184], indicating increasing blood involvement).

Results

Investigator‐assessed PFS was longer for mogamulizumab versus vorinostat across all blood classes, significantly so for B1 and B2 patients. ORR was higher with mogamulizumab than with vorinostat in all blood classification groups and more markedly so with escalating B class (B0: 15.6% vs. 6.5%, P = 0.0549; B1: 25.8% vs. 6.5%, P = 0.2758; B2: 37.4% vs. 3.2%, P < 0.0001). TTNT was significantly longer for patients treated with mogamulizumab versus vorinostat with B1 (12.63 vs. 3.07 months; HR 0.32 [95% CI 0.16–0.67]; P = 0.0018) and B2 (13.07 vs. 3.53 months; HR 0.30 [95% CI 0.21–0.43]; P < 0.0001) blood involvement. In the mogamulizumab arm, 81 patients (43.5%) had ≥50% change in the mSWAT vs. 41 patients (22.0%) with vorinostat; mSWAT improvements with mogamulizumab occurred most often in B1 and B2 patients. Rapid, sustained reductions were seen in CD4⁺CD26^‐ cell counts and CD4:CD8 ratios in mogamulizumab patients for all B classes. Treatment‐emergent adverse events were less frequent overall with mogamulizumab and similar in frequency regardless of B class.

Conclusions

This post hoc analysis indicates greater clinical benefit with mogamulizumab vs. vorinostat in patients with MF and SS classified as having B1 and B2 blood involvement.

Treatment of early-stage mycosis fungoides: results from the PROspective Cutaneous Lymphoma International Prognostic Index (PROCLIPI) study

BACKGROUND

The PROspective Cutaneous Lymphoma International Prognostic Index (PROCLIPI) study is a prospective analysis of an international database. Here we examine front-line treatments and quality of life (QoL) in patients with newly diagnosed mycosis fungoides (MF).

OBJECTIVES

To identify (i) differences in first-line approaches according to tumour-nodes-metastasis-blood (TNMB) staging; (ii) parameters related to a first-line systemic approach and (iii) response rates and QoL measures.

METHODS

In total, 395 newly diagnosed patients with early-stage MF (stage IA-IIA) were recruited from 41 centres in 17 countries between 1 January 2015 and 31 December 2018 following central clinicopathological review.

RESULTS

The most common first-line therapy was skin-directed therapy (SDT) (322 cases, 81·5%), while a smaller percentage (44 cases, 11·1%) received systemic therapy. Expectant observation was used in 7·3%. In univariate analysis, the use of systemic therapy was significantly associated with higher clinical stage (IA, 6%; IB, 14%; IIA, 20%; IA-IB vs. IIA, P < 0·001), presence of plaques (T1a/T2a, 5%; T1b/T2b, 17%; P < 0·001), higher modified Severity Weighted Assessment Tool (> 10, 15%; ≤ 10, 7%; P = 0·01) and folliculotropic MF (FMF) (24% vs. 12%, P = 0·001). Multivariate analysis demonstrated significant associations with the presence of plaques (T1b/T2b vs. T1a/T2a, odds ratio 3·07) and FMF (odds ratio 2·83). The overall response rate (ORR) to first-line SDT was 73%, while the ORR to first-line systemic treatments was lower (57%) (P = 0·027). Health-related QoL improved significantly both in patients with responsive disease and in those with stable disease.

CONCLUSIONS

Disease characteristics such as presence of plaques and FMF influence physician treatment choices, and SDT was superior to systemic therapy even in patients with such disease characteristics. Consequently, future treatment guidelines for early-stage MF need to address these issues.

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.

Quality of Life Effect of the Anti-CCR4 Monoclonal Antibody Mogamulizumab Versus Vorinostat in Patients With Cutaneous T-cell Lymphoma

BACKGROUND

Sézary syndrome (SS) and mycosis fungoides (MF), 2 types of cutaneous T-cell lymphoma, cause significant morbidity and adversely affect patients' quality of life (QoL). The present study assessed the QoL measurement changes in patients receiving mogamulizumab versus vorinostat.

PATIENTS AND METHODS

A multicenter phase III trial was conducted of patients with stage IB-IV MF/SS with ≥ 1 failed systemic therapy. The QoL measures included Skindex-29 and the Functional Assessment of Cancer Therapy-General. The symptoms, function, and QoL subdomains were longitudinally modeled using mixed models with prespecified covariates. Meaningful change thresholds (MCTs) were defined using distribution-based methods. The categorical changes by group over time and the time to clinically meaningful worsening were analyzed.

RESULTS

Of the 372 randomized patients, mogamulizumab demonstrated improvement in Skindex-29 symptoms (cycles 3, 5, and 7; P < .05) and functional (cycles 3 and 5; P < .05) scales. A significantly greater proportion of mogamulizumab-treated patients improved by MCTs or more from baseline in the Skindex-29 symptoms domain (cycles 3, 5, 7, and 11) and functioning domain (cycle 5). Significant differences in the Functional Assessment of Cancer Therapy-General physical well-being (cycles 1, 3, and 5; P < .05) were observed in favor of mogamulizumab and a greater proportion of patients had declined by MCTs or more at cycles 1, 3, 5, and 7 with vorinostat treatment. The median time to symptom worsening using Skindex-29 was 27.4 months for mogamulizumab versus 6.6 months for vorinostat. In the patients with SS, the time to worsening favored mogamulizumab (P < .005) for all Skindex-29 domains. The time to worsening was similar for the 2 MF treatment arms.

CONCLUSION

The symptoms, function, and overall QoL of patients with MF/SS favored mogamulizumab over vorinostat across all time points. Patients with the greatest symptom burden and functional impairment derived the most QoL benefit from mogamulizumab.

Cutaneous T-Cell Lymphoma: Optimizing Care in Patients Receiving Anti-CCR4 Monoclonal Antibody Mogamulizumab

BACKGROUND

Cutaneous T-cell lymphoma (CTCL), including subtypes mycosis fungoides (MF) and Sézary syndrome (SS), represents a rare group of non-Hodgkin lymphomas. Mogamulizumab is a first-in-class monoclonal antibody that selectively binds to C-C chemokine receptor 4, which is overexpressed on the surface of tumor cells in T-cell malignancies, including MF/SS-type CTCL.

OBJECTIVES

This review identifies common diagnostic features of MF/SS, the efficacy and side effect profile of mogamulizumab, and practical management strategies for optimizing the nursing care of patients with MF/SS-type CTCL.

METHODS

Case studies are used to describe the role of mogamulizumab in CTCL and to review practical considerations when administering mogamulizumab to patients.

FINDINGS

Mogamulizumab is an effective treatment for adult patients with relapsed or refractory MF/SS-type CTCL who have received at least one prior systemic therapy. Infusion reactions and drug eruptions require prompt diagnosis and treatment.

Quality of Life, Anxiety, and Depression in Patients With Early-Stage Mycosis Fungoides and the Effect of Oral Psoralen Plus UV-A (PUVA) Photochemotherapy on it

Background: Little is known about psychological discomfort and quality of life (QoL) in early stage mycosis fungoides (MF) and the effect of psoralen plus UV-A (PUVA) on it.

Objective: To evaluate QoL, anxiety, and depression with validated instruments in early stage MF patients and whether PUVA treatment improves it.

Methods: Patients with stage IA to IIA MF were treated with PUVA twice weekly for 12–24 weeks, followed by maintenance treatment or not, in a prospective randomized clinical trial. Patients completed a questionnaire on DLQI as well as the Hospital Anxiety and Depression Scale (HADS) prior to therapy, after their last PUVA exposure, and after the PUVA maintenance or observance phase.

Results: For 24 patients with early stage MF, completed questionnaires were available and analyzed. Prior to treatment, 17% reported strong (DLQI > 10) and 29% moderate impairment (DLQI 6–10) in QoL; 33% of patients reported HADS scores indicating anxiety, and 21% reported scores indicating depression. PUVA significantly improved overall QoL by reducing mean DLQI scores by 58.6% (p = 0.003), HADS-A by 30% (p = 0.045), and HADS-D by 44% (p = 0.002). Improvements in QoL and psychological well-being seemed to be sustained, irrespective of maintenance treatment or not.

Limitations: Small sample size.

Conclusions: PUVA sustainably improves QoL and psychological well-being in patients with early stage MF.

Clinical trial registration:ClinicalTrials.gov identifier: NCT01686594.

Current measures are not sufficient: an interview-based qualitative assessment of quality of life in cutaneous T-cell lymphoma

BACKGROUND

Cutaneous T-cell lymphoma (CTCL) negatively impacts quality of life (QoL), but existing QoL questionnaires may not comprehensively reflect patients' experience.

OBJECTIVES

To identify the aspects of QoL that are most meaningful to patients with CTCL and to evaluate existing QoL instruments in this context.

METHODS

Semistructured interviews were conducted between May and June 2019 using purposive sampling of patients with CTCL. Data were analysed by an inductive thematic approach using Dedoose Version 8.0.35.

RESULTS

One-on-one interviews lasting a median of 43 min were completed by 18 patients [median age 62 years (interquartile range 52-70); 39% advanced-stage (IIB-IV)]. Itch was the most common clinical symptom reported (16 of 18 patients), followed by pain (12 of 18), skin breaks (11 of 18) and skin flaking (10 of 18). Eleven patients reported that their symptoms interfered with sleep, which impacted daily functioning. Patients also noted a lack of understanding of the disease in the community and felt uncertain (12 of 18), depressed (11 of 18), suicidal (four of 18) and hopeless (nine of 18). Nearly all patients (17 of 18) reported a sense of 'otherness' (not feeling 'normal' or 'like themselves'), and most patients (16 of 18) specifically mentioned concern about their physical appearance. Patients also noted substantial treatment burden. Salient patient concerns, including individual clinical symptoms, concern about appearance and problems with sleep, were not adequately or consistently represented in generic, skin-specific or CTCL-specific QoL measures.

CONCLUSIONS

Incorporating the concerns and priorities that distinguish patients with CTCL from other patient populations will be of paramount importance in developing a comprehensive CTCL-specific measure of QoL that adequately captures patients' experience.

Pathogenesis and Therapy of Primary Cutaneous T-Cell Lymphoma: Collegium Internationale Allergologicum (CIA) Update 2020

Cutaneous T-cell lymphoma (CTCL) is a heterogeneous disease group of unknown etiology with a complex immunological background. As CTCL arises from T cells that have a vital role in the antitumor response, their therapy is largely aimed at reversing the immunological mechanisms leading to or manifesting during this malignancy. Early disease stages can be controlled with skin-directed therapy in most CTCL cases. Still, advanced CTCL has a dismal prognosis and warrants systemic therapy. Despite considerable progress in understanding the pathophysiology of the disease and the numerous systemic treatment options available, long-term remission rates with conventional treatments alone are still low. Allogeneic hematopoietic stem cell transplantation is currently the only curative option for advanced CTCL, including mycosis fungoides and Sézary syndrome. The aims of this review is to summarize the recent findings on the immunology of this heterogeneous disease and to present the advances in its clinical management.

Patient-reported quality of life in patients with relapsed/refractory cutaneous T-cell lymphoma: Results from the randomised phase III ALCANZA study

BACKGROUND

Brentuximab vedotin was approved for adult patients with CD30-expressing cutaneous T-cell lymphoma treated with prior systemic therapy based on improved response rates and progression-free survival with brentuximab vedotin (1.8 mg/kg once every 3 weeks; ≤16 cycles) versus physician's choice (methotrexate/bexarotene; ≤48 weeks) in the phase III ALCANZA study. Quality of life (QoL) in ALCANZA patients was also examined.

METHODS

QoL measures in ALCANZA were based on the Skindex-29, Functional Assessment of Cancer Therapy-General (FACT-G) and European QoL 5-dimension (EQ-5D) questionnaires.

RESULTS

Mean maximum reduction from the baseline Skindex-29 symptom domain score (key secondary end-point) was greater with brentuximab vedotin than physician's choice (-27.96 versus -8.62); the difference, -18.9 (95% confidence interval -26.6, -11.2; adjusted p < 0.001), exceeded the study-defined minimally important difference (9.0-12.3). Mean changes from baseline to end-of-treatment visit total FACT-G scores were similar with brentuximab vedotin and physician's choice (0.15 versus -2.29). EQ-5D changes were also comparable between arms. Among brentuximab vedotin-treated patients with peripheral neuropathy (PN), mean maximum reduction in Skindex-29 symptom domain was -35.54 versus -11.11 in patients without PN. PN had no meaningful effect on FACT-G and EQ-5D QoL scores.

CONCLUSIONS

In summary, brentuximab vedotin produced superior reductions in symptom burden compared with physician's choice, without adversely impacting QoL. QoL was unaffected by the presence of PN in brentuximab vedotin-treated patients.
