Associations between body composition parameters and tumour immune cell infiltration were analysed using ANOVA.<h4>Results</h4>Patients with low muscle radiodensity (myosteatosis) had a lower proportion of stromal CD45-positive cells than patients with normal muscle radiodensity (21.6% ± 21.90% vs. 34.85% ± 25.55%; p = 0.04). Here, PTPRC is linked to neoplasm.
