Fig. 6: Kaplan–Meier curves generated in accordance with the distribution patterns of immune cell infiltration in the study patients with anorectal malignant melanoma (ARMM).

a Patients with a brisk total tumor infiltrating lymphocytes (TIL) (sum of CD3+, CD8+, and Foxp3+ T cell) show better overall survival (OS) rates than those with a non-brisk TIL or absent TIL. b Patients with CD3 + TIL show better OS rates than those with a non-brisk TIL or absent TIL. c, d Patients with an inflamed phenotype have significantly better OS and recurrence free survival (RFS) rates than patients with an immune-desert and immune-excluded phenotype.
