More differentiated information to fine-tune your treatment decision

Axillary management and the relevance of sentinel lymph node biopsy (SLNB) have undergone major changes in the last years. Clinical trials, which have investigated less invasive treatment approaches as a replacement of axillary surgery, indicate that axillary dissection can be omitted in patients with limited metastatic involvement. Consequently, treatment decisions and nodal staging more often have to be based solely on the diagnostic information derived from the sentinel lymph node (SLN).

More than 100 publications provide evidence on the clinical utility of using OSNA and the CK19 copy number for SLN assessment. They show that CK19 provides predictive and prognostic information beyond conventional pathology assessment. This helps clinicians better select who can be safely spared an ALND, allows more personalised treatment decisions and improves patients’ quality of life.
