Health-Related Quality of Life (HRQL) in Cutaneous T-Cell Lymphoma: Psychological Burden and Influencing Factors from Mycosis Fungoides and Sézary Syndrome Patients in China

Abstract

Introduction: Mycosis fungoides (MF) and Sézary syndrome (SS) are the most common subtypes of cutaneous T-cell lymphomas (CTCL). However, beyond the clinical and economic burden, psychological burden from CTCL patients in China has not been reported and requires further evaluation. Methods: The analysis used data from adults (≥18 years) clinically diagnosed with MF or SS, and have been receiving or have received disease-related treatment in the past year. MF patients with stage IA-IIA, patch or plaque phase were categorized into early stage, while stage IIB-IVA, tumor phase were late stage. All SS patients are late stage. HRQL data from the EQ-5D-5L, Skindex-29 and Functional Assessment of Cancer Therapy - General (FACT-G) were analysed at the item level and scored according to instrument guidelines. Multivariate analyses were used to identify factors associated with poor HRQL. Results: Data were collected from a quantitative survey of 56 MF patients and 5 SS patients residing in 38 cities of 21 provinces across China: 56% were male, with a mean (SD) age of 39 (13) years (median was 38, ranged 19 to 74 years old). 51% were late stage. Based on emotional domain questions of Skindex-29, among all patients, 39% always or often worried about the disease progression, while 45% of late-stage patients were always and often worried. 36% of all patients often or always felt CTCL was annoying. Based on FACT-G, in physical well-being domain, 39% of all patients, and 48% of late-stage patients felt they were ill in “quite a bit” or “very much” scale, respectively. In social well-being domain, 35% of all, and 39% of early-stage patients felt “not at all” or only “a little bit” satisfied with their sex life. In emotional well-being domain, 38% of all patients were “not at all” or “a little bit” satisfied with their coping with the disease, while 36% of all patients “quite a bit” or “very much” worried about the condition getting worse. In the functional well-being domain, 29% of all patients felt they were “not at all” or “a little bit” able to work. In multivariate analysis, regression on EQ-5D-5L score showed that younger patients were more likely to report severe anxiety and depression. Skindex-29 score showed that female patients worried more that the disease get more serious and causing scars on their skin. Conclusions: In China, psychological burden with MF and SS, included anxiety, depression, worrying about disease progression, unable to work, and unsatisfied sex life. Younger patients and female patients reported greater psychological impact of the disease. Optimal medical management of MF and SS should address psychological impacts of the disease.
