Abstract

Extranodal natural killer/T-cell lymphomas (NKTCL) is a rare and aggressive extranodal non-Hodgkin lymphoma. These evidence-based recommendations for NKTCL by the American Radium Society were developed by a multidisciplinary panel of medical oncologists 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 NKTCL clinical presentation. Six variants highlight the recommended treatment strategies.
