microRNA expression profiles of tumor-positive and tumor-negative sentinel lymph node biopsies from cutaneous melanoma patients

We analyzed microRNA profiles in archival FFPE sentinel node biopsy (SNB) from melanoma patients with different outcomes. Tumor-negative SNB (N), and tumor-positive SNB from patients with (PP) or without disease progression at 5 years follow-up (PN) were analyzed. This is a pilot study assessing 24 sentinel node biopsies from 24 melanoma patients. Each biological group contains 8 samples.
