Background
Pruritus can be a distressing and even debilitating symptom for patients with cutaneous T-cell lymphoma (CTCL). To date, few studies have evaluated the pathophysiology of this symptom. Due to this, therapy for pruritus in CTCL has mainly relied on those therapies that target and treat the lymphoma. For patients living with CTCL that relapses or becomes refractory to treatment, and who continue to experience severe itch, this lymphoma-targeted treatment may not be enough to combat their pruritus. Therefore, other itch-targeted therapies are needed for use in this disease
Objective
Evaluate the current evidence regarding the mechanism of action and treatments for pruritus associated with cutaneous T-cell lymphoma.
Methods
An explicit and thorough search was restricted to all peer-reviewed literature available through MEDLINE (1950 to September 2011) and pubmed.org. Search terms used were pruritus, cutaneous T-cell lymphoma (CTCL), mycosis fungoides (MF), and Sézary Syndrome (SS). All studies that involved pruritus in either CTCL, MF, or SS were evaluated by all three authors.
Results
The current literature helps to identify therapies and possible mechanisms for treating patients with CTCL associated pruritus. .
Limitation
Most studies were pre-clinical. Only studies involving mechanisms of action or treatment were included
Conclusion
A guideline is necessary to assist in the treatment of pruritus in CTCL and additional studies are necessary to uncover the exact mechanism(s) of action.
