Methods for diagnosing hematological cancers

Abstract

The present disclosure relates to methods for diagnosing hematological cancers. In particular, the present invention relates to a method for diagnosing a hematological cancer in a patient comprising i) detecting the presence of CD45RARO NK cells in a sample obtained from the patient and ii) and concluding that the patient suffers from a hematological cancer when the presence of CD45RARO NK cells is detected in the sample and the presence of at least one phenotypic marker indicates the nature of the haematological cancer.
