Fig. 2From: Tumor microenvironment-derived S100A8/A9 is a novel prognostic biomarker for advanced melanoma patients and during immunotherapy with anti-PD-1 antibodiesHigh numbers of S100A8/A9 positive cells are associated with metastasis of primary melanoma. Dot plot showing the proportion of S100A8/A9 positive myeloid cells in nevi (N = 50), non-metastasizing primary melanomas (NMPMM; N = 41), and metastasizing primary melanomas (MPMM; N = 13) on TMA 1. Black horizontal lines indicate median proportions of S100A8/A9 positive cells. P values were calculated using two-sided Whitney-Mann U test. Abbreviations: MPMM = metastasizing primary melanoma, NMPMM = non-metastasizing primary melanoma, P = P-value, TMA = tissue microarrayBack to article page
