Executive Summary of the American Radium Society Appropriate Use Criteria for Extranodal Natural Killer/T-cell Lymphoma.

Extranodal natural killer/T-cell lymphoma is a rare and aggressive extranodal non-Hodgkin lymphoma. These evidence-based recommendations for natural killer/T-cell lymphoma by the American Radium Society were developed by a multidisciplinary panel of medical and radiation oncologists to propose treatment approaches. This guideline was based on a literature review with a consensus methodology to rate the appropriateness of treatment recommendations for each natural killer/T-cell lymphoma clinical presentation. Six variants highlight the recommended treatment strategies.
