Topical treatments for early-stage mycosis fungoides using Grading Recommendations Assessment, Development and Evaluation (GRADE) criteria: A systematic review

Mycosis fungoides (MF) is a cutaneous lymphoma; most patients present with early, skin-limited disease and are managed by dermatologists. The purpose of this study was to systematically review and assess the evidence on topical treatments for early-stage (IA, IB, IIA) MF. We performed a literature s...

Description
Summary:Mycosis fungoides (MF) is a cutaneous lymphoma; most patients present with early, skin-limited disease and are managed by dermatologists. The purpose of this study was to systematically review and assess the evidence on topical treatments for early-stage (IA, IB, IIA) MF. We performed a literature search via MEDLINE, Embase, Web of Science, and Cochrane databases. Grading Recommendations Assessment, Development and Evaluation (GRADE) criteria were used to assess the certainty of the data. Two searches yielded 1252 references; 26 met the inclusion criteria and included literature on nitrogen mustard, retinoids, corticosteroids, carmustine, fluorouracil, methotrexate-laurocapram, hexadecylphosphocholine, peldesine, ingenol mebutate, topical methotrexate with oxygen flow-assisted LP3 carrier, and resiquimod. Most studies were single intervention, observational series. Nitrogen mustard, with the most published reports, was effective with 12%-82% early-stage MF patients (total n > 1000) achieving complete remission (CR) (low certainty evidence). Clinical CR was achieved among 10%-60% treated with topical retinoids (low certainty evidence). Two moderate-sized retrospective case series on topical steroids had 18%-63% CR (low certainty evidence). Only single studies were available for the other therapies. For most outcomes of interest, the GRADE certainty for topical therapies for early-stage MF was low. Further randomized controlled trials and inclusion of quality of life indicators are needed.
