Short term (median follow-up of 16 months) clinical course data were consistent with nm23 RNA levels, in that 2 of 11 low nm23 RNA content patients (including one from the 0 involved lymph node group) developed metastases, while none of the high nm23 RNA patients have experienced recurrent disease.

The present study was designed to investigate whether nm23 RNA was detectable in human tumor tissue, and if it was differentially expressed. nm23 RNA levels in 27 human primary infiltrating ductal breast carcinomas were determined by using Northern blots or in situ hybridization.
