CD2+ count predicts OS and RFS. a Kaplan–Meier survival curves for patients with ulcerated melanoma, stratified using median CD2+. Each slide was evaluated twice, independently, by blinded investigators using an ocular micrometer with a 1 mm2 130 grid (Nikon Eclipse E400®) and the number of CD2+ cells in eight high-powered fields (HPF) was averaged to yield a single score for use in subsequent analyses. High CD2+ count correlates with longer OS (p = 0.042) and b RFS (p = 0.0087). In non-ulcerated melanoma, CD2+ count does not correlate with c OS (p = 0.283) or d RFS (p = 0.846). e Representative images of e CD2+ low and f CD2+ high stained with anti-CD2 antibody (shown at 40×, 100×, inset) magnifications
