Objective: Narrowband ultraviolet B (NB-UVB) has been recommended as first-line therapy for early-stage mycosis fungoides (MF) in international guidelines. NB-UVB can be used as monotherapy or part of a multimodality treatment regimen. There is limited evidence on the effectiveness and optimal patients of NB-UVB in combination with systemic therapies in MF.

Objective: To determine the prognostic factors and survival outcomes of patients with MF among a cohort in China.
Design, Setting, And Participants: This was a retrospective cohort study of patients with MF who received treatment at a tertiary referral center for skin lymphoma (Peking University First Hospital, Beijing, China) from August 1, 2009, to August 31, 2021.
Cutaneous T cell lymphoma (CTCL) represents a heterogeneous group of non-Hodgkin lymphoma distinguished by the presence of clonal malignant T cells. The heterogeneity of malignant T cells and the complex tumor microenvironment remain poorly characterized. With single-cell RNA analysis and bulk whole-exome sequencing on 19 skin lesions from 15 CTCL patients, we decipher the intra-tumor and inter-lesion diversity of CTCL patients and propose a multi-step tumor evolution model.

To identify the molecular driver of LCT, we collected tumor samples from 133 MF patients and performed whole-transcriptome sequencing on 49 advanced-stage MF patients, followed by integrated copy number inference and genomic hybridization. Tumors with LCT showed unique transcriptional programs and enriched expressions of genes at chr7q.
